10 Questions To Ask Before You Choose A Roof

Choosing the correct replacement for an aged roof – or identifying the best choice for a new building – is no easy task. The perfect roofing solution for one building may be the worst option for another just down the street. That’s because no two buildings are precisely alike, even if they closely resemble each other. So how do you choose a new roof, given all the choices in the marketplace? You can start by asking a series of questions, before you choose the roof, the roofing contractor or the manufacturer.

1. What is this building’s mission statement?

Before calls are made to roofing contractors or manufacturers, the first item to address is the company’s mission statement as it relates to the building.

Whether you are building new facilities or managing existing properties, you want to be confident that the roofing systems you select deliver the performance you expect. More often than not, the building itself dictates the appropriate roofing system specification.

You need to know as much about the building and its future as possible. Does the company plan to keep this building as part of its real estate assets for the next 10 to 20 years? Are there any plans to expand it in the near future, or to change its use? What are its current and future occupancy, insulation requirements, aesthetic priorities and even the maintenance schedules for rooftop equipment?

These and other mission statement issues will help shape answers to types of roofing to consider and how much of the capital budget is really needed for the job.

Start your questions with what is the building going to be used for. If it’s a spec building, maybe you only need a basic roof. But, if the facility has a special use, such as an airline reservation center with computers in it, then your considerations for roofing options are quite different.

For example, as more companies move toward operating 24 hours daily, seven days a week to satisfy global customers, the data center must never spring a rooftop leak. Water on computer systems generally spells disaster.

A special set of concerns arise for cooling-dominated climates. Does the roof contribute to air conditioning savings and address other key issues? Is it part of a total energy program? There is a growing concern about urban heat islands. Reflective, white roofs have become of interest in those areas for a few reasons. They keep the building cooler, reduce air conditioning costs and also minimize the heat-loading of the surrounding environment.

2. What physical and other elements influence the roofing system selection?

After identifying the goals and mission of a facility, it’s time to evaluate the building itself. You need to begin by looking at the building’s location and the attributes of its surrounding area. You need to examine building codes, weather trends, topography – even the direction the building faces.

The physical characteristics of the building are also crucial: size, shape, design, height and age.
You also need to look at the construction materials used to build the facility and the location of HVAC and fire protection equipment, particularly if either or both of these are partially or totally housed on the rooftop.

When it comes to roof replacement, you need to list the attributes of the roof area itself. It’s best to detail the roof’s size, shape, slope, deck construction, edge detailing, protrusions, rooftop access and existing roofing system. Along with this basic information, you need to find out why the original roof is no longer adequate.

3. What flexible-membrane roofing options are available?

SPRI, the association that represents sheet membrane and component suppliers to the commercial roofing industry, identifies three major categories of membranes: thermosets, thermoplastics and modified bitumens.

Thermoset membranes are made from rubber polymers. The most common is EPDM, often referred to as “rubber roofing.” These membranes are well suited to withstand the potentially damaging effects of sunlight and the common chemicals found on roofs. They are easily identified on the rooftop. Just look at the seams. Thermoset membranes require liquid or tape adhesives to form a watertight seal at the overlaps.
Thermoplastic membranes are based on plastic polymers. The most common is PVC, which is made flexible by adding plasticizers. Thermoplastic membranes have seams that are most commonly formed using heat welding. Most thermoplastic membranes are manufactured with a reinforcement layer, usually polyester or fiberglass to provide increased strength and dimensional stability.

Hypalon thermoplastic begins as a thermoplastic, but cures over time to become a thermoset. Like other thermoplastics, Hypalon materials are heat sealed at the seams.

Another thermoplastic hybrid is thermoplastic polyolefin (TPO), which combines the attributes of EPDM and PVC. TPO membranes do not cure after exposure to the elements and remain hot-air weldable throughout their service life. Most TPO membranes are reinforced with polyester, fiberglass or a combination of the two, but unreinforced TPO membranes are available.

Modified bitumen membranes incorporate the formulation and prefabrication advantages of flexible-membrane roofing with some of the traditional installation techniques used in built-up roofing. Modified bitumen sheets are factory-fabricated, composed of asphalt which is modified with a rubber or plastic polymer for increased flexibility, and combined with a reinforcement for added strength and stability.

4. Which type of membrane and attachment system are best for the building?

Many factors determine the best system for a particular building. For most buildings, there are a number of options and advantages that need to be weighed against the facility’s mission statement. The decision should not be made only on the basis of cost. Other important considerations for membranes are building height, wind exposure, anticipated roof traffic and aesthetics.

The attachment system also depends on the specific building’s characteristics. If the roof deck is able to withstand the weight, a ballasted roof may be the best option. But, if the slope of the roof is greater than 2 inches every foot, this system may not be appropriate. There are other limitations to ballasted systems, such as roof height, proximity to shorelines and other high wind zones, and the availability of ballast.
A steel or wood deck that easily accepts fasteners makes a good substrate for a mechanically fastened membrane. These systems can be designed to provide the necessary resistance to known wind forces and are not subject to slope limitations.

Another alternative is the fully adhered system, in which the membrane is attached to the prepared substrate using a specified adhesive. Depending on the membrane, the adhesive may be solvent- or water-based or asphalt. The finished surface of an adhered roof is smooth.

For those concerned with building aesthetics, colored membranes can make an attractive contribution to the building’s appearance.

5. Does all roofing material delivered to the job site bear the UL label?

If not, specify that it must. This is the only way you can guarantee that the roofing materials installed on your roof are the same materials tested by Underwriter’s Laboratories. Additionally, be sure that the roof assembly you buy or specify, which includes the insulation, is UL-classified and -labeled. Using an insulation other than what was tested with the roofing membrane may void the UL classification. If the UL Building Materials Directory does not list the roofing system you are sold, insist on verification of the classification in the form of a photocopy of the UL’s letter of approval.

Make sure that the product you are getting is the actual product that was tested. You don’t want something that is similar but not equal. Look for the label at the job site and make sure all components of the system were tested together. You want the membrane tested with the insulation that you are using on your building.

6. Does the system require a wind uplift rating?

Wind uplift damage can be extensive and expensive. Accepted as an industry standard, American Society of Civil Engineers Standard 7-95, “Minimum Design Loads for Buildings and Other Structures,” can be used to determine the wind zone of the building. Wind uplift testing, such as that performed at Factory Mutual or Underwriters Laboratories, can be used to determine that the selected roof system meets or exceeds the local wind uplift requirements.

7. How much does the completed system add to the dead load weight of the roof structure?

In choosing any reroofing option, the facility executive should be aware of the load-bearing capacity of the roof deck to make sure the right flexible-membrane option is chosen. In new construction, savings in structural steel can often be achieved by installing one of the lighter flexible-membrane systems.

A ballasted thermoplastic or EPDM roof may require in excess of 1,000 pounds per 100 square feet, while a mechanically attached or fully adhered thermoset or thermoplastic membrane weighs 33 pounds per 100 square feet. A lighter system often allows you to reroof directly over your existing roof, while the heavier ones may require you to tear off the old roof and begin anew. But weight is only one consideration in the selection of a roof membrane and attachment system. A ballasted roof may be the best choice for a given facility. Facility executives must assure that all relevant considerations, including weight, are taken into account in the decision-making process.

8. What are the expertise and financial strengths of the roofing contractor you are considering?

Roofing contractors need to be chosen with great care. The introduction of new roofing materials and application techniques within the past 10 years has led to many changes. A professional roofing contractor should be familiar with different types of roofing systems, to help you make the best decision for your facility, based on your budget.

Ask the contractor if his or her company is a member of a local, state, regional or national industry association. Contractors involved in professional associations generally are better informed on the latest developments and issues of their industry.

Insist the contractor supply you with copies of insurance certificates that verify workers’ compensation and general liability coverages. Check that those coverages are in effect for the duration of your roofing job. If the contractor is not properly insured, your company, as the property owner, may be liable for accidents occurring on the property. Also check your state’s licensing requirements and find out if the contractor is bonded by a surety company.

The installation of different roofing systems varies considerably. Education and training are the most important elements in the installation of roofing systems. Make sure the roofing contractor you choose has had detailed and ongoing training on the system being installed.

One rule of thumb is to find out if the contractor has installed at least 100,000 square feet of the system you want in the past 18 months. Also, make sure the contractor is approved by the manufacturer to install that specific system.

The quality of workmanship is crucial to good roof performance. The National Roofing Contractors Association offers a professional roofing selection guide. In addition, many manufacturers have approved contractor programs with specific qualifications that roofers must complete before approval.

9. What is warranted and by whom?

There are two basic categories of roofing warranties. The contractor’s warranty typically covers workmanship. The manufacturer’s warranty covers at least the materials, though many cover additional items. Even if the manufacturer’s warranty is broad, it will not completely protect you if the roof is improperly installed.

Carefully read and understand any roofing warranty offered and watch for provisions that would void it. For example, it’s nearly impossible to avoid all ponded water. Ponded water can be caused by a clogged roof drain or deflection of the roof deck in between the support columns. Proper roof maintenance can help assure that the warranty remains valid. Be aware of warranty language that voids the guarantee.

Most professional roofing contractors will offer periodic maintenance inspections throughout the year. These inspections help ensure your project complies with the standards specified in the warranty. A typical maintenance program consists of a detailed visual examination of the roof system, flashing, insulation and related components to identify any potential trouble areas.

More important than the warranty, however, is getting the right flexible-membrane roof on your building in the first place. If the roof is correctly designed and installed to meet your facility’s needs, building codes and geographical considerations, and the warranty covers those needs, you probably will be enjoying the benefits of a flexible-membrane roof many years after the original warranty expires.

10. After the roof is installed, what after service and educational programs are available for the facilities management team?

Seminars offered by roofing industry associations like SPRI and manufacturers can be invaluable ways for the building’s roofing team to expand their understanding of commercial roofing system types, installation processes and maintenance considerations. Specific courses are available to help building owners and facilities managers learn more about various roofing systems, materials and components; insulation and accessory products; elements of roof design; contractor selection; warranties and maintenance considerations.

In This Economy, Don’t Replace Your Roof If All It Needs Is Roof Repair

Let’s face it – the prospect of a leaking roof, particularly in the middle of winter, is a scary proposition. There is no arguing that a brand new roof will provide you with a greater sense of security than repairing a damaged roof far beyond its serviceable life. Because of this reason, many unscrupulous roofing contractors will use scare tactics to get homeowners to opt for a new roof replacement versus a repair on a roof that has much life remaining. A quick review of a few critical items will help you feel more confident if you should be seeking replacement or looking to repair.

First, you need to evaluate different criteria based on whether your suspicion that you need a new roof is based on either a roof leak or a roof that is dirty (stains, moss, etc.) If the primary reason you think it is time for a new roof is because of a roof leak, you need to clarify a few issues regarding that leak.

Determine whether or not the roof leaks in a single or multiple locations, and whether it is in a location that has leaked and been repaired repeatedly. A single location, leaking for the first time, usually is not by itself going to be an absolute indication of needing to replace the entire roof. More likely that not, a single component of the roofing system (flashing, vent, a mis-nailed shingle) has failed but the rest of the roof still could be in decent condition. Leaks in multiple locations bode more ominous results.

If multiple locations are having shingles loosen, nails rise, flashing fail, the chance of the roof being worn out are much higher. When the same location has leaked and been repaired repeatedly, it may never have been adequately addressed and the same mistaken repair may be continuing to be performed. It will be critical to get an assessment for a roof leak repair expert as to whether there is something un-repairable or if the past repairs addressed the wrong issue. Don’t let one bad spot to cost you an entire new roof!

Next, look at the roof leak location. Is it below, or in somewhat of a direct path below a skylight, vent, or pipe? Is it possibly at a valley or roof intersection where either on sections of roof meets another or where the roof meets a wall? Or rather is it out in middle of roof field? Leaks at intersections and valleys usually do not indicate by themselves that a roof is finished. More likely, there are flashing issues. Leaks in the middle of a roof field with no nearby intrusions into the roof can be a bad sign.

Remember, there are very few leaks that are un-repairable. The issue becomes whether the roof has adequate remaining life to justify the repair’s cost.

If an unsightly roof (fungus or mildew stains or moss growth) is what is making you think you need a new roof, you need to learn more about what is under the stains or moss. There is not always a correlation to a dirty roof and it’s life being over. There are most certainly roofs that will not withstand even the gentlest possible roof cleaning without sustaining damage that puts it in poor condition. Particularly with moss, as experienced in the Portland Oregon area, there are some moss types and infestations that cannot be properly dislodged without stressing a roof. If a roof is on the borderline to start with, such a roof is best left alone and the funds save for going toward a new roof.

That exception being made, most roofs that are simply dirty would benefit for the gentlest cleaning available to solve its particular issue. Cleaning the roof will most often help maintain roof life, specifically where growths such as moss could cause “micro-dams” on the roof and result in damage. Always be sure that the roof has adequate life remaining so that your maintenance dollars will not be wasted.

For composition roofs (the most common type), granules, or lack there of, are the primary indicator of remaining roof life, much like the tread on a tire. If a roof consistently has lost a lot of its granules it is definitely time to replace it. Without an adequate amount of granule, which helps reflect the UV rays and protect the more sensitive lower layers of the material, the roof will soon be leaking. However, if the roof has enough granules that you consistently cannot see the underlying composition layers, the chances are good that, withstanding other issues, it might have more life remaining.

Even with adequate granule, if the roof’s shingles are starting to cup or curl upward, it may also be time to consider replacing. Cupping and curling often are signs of interior ventilation issues that result in excessive attic temperatures. It is a problem you would want corrected with the new roof installation because it takes life off a roof that otherwise might have had more life remaining.

Loose or dislodged shingles may signal an unfortunate, premature death of your roof. Quite often this is a sign that the roofing material was victim of an installation faulty, even if the material itself has more life remaining. Similar to leaks, the number of trouble spots will tell you a lot. If it is only one trouble spot, you will likely only need to go with a repair. Multiple locations, however, indicate the bad installation mentioned above and you will need to get it replaced.

The majority of calls we receive thinking a new roof is needed as a result of homeowner diagnosed issues actually end up being repairs. However, if the homeowner has taken the roof’s age as part of equation (for instance, the roof is near or beyond the manufacturer’s age span,) then the results reverse and we see the majority of those roofs requiring replacement. Quite often, homeowners understandably don’t know age of their roof, for instance if they moved into a pre-existing home where the previous owners were not original owners. In that case, they are very dependent on an expert’s opinion, but it must also be an honest one!

Regardless of what is causing you to thing you may need a new roof, slow down. A day of two of analyzing these critical considerations may save you thousands of dollars.

What Every Homeowner Should Know About Emergency Roof Repair

As tough and durable as it may be, your roof was not designed to stand up to extreme weather. The high winds and driving rains that come with most major storms can do serious damage to the essential structure – not to mention lightning, hail, and falling trees. What should you expect when you request emergency roof repair? Let’s find out.

When To Call

Before we discuss repairs, it’s important to explain what qualifies as a roofing emergency. As we mentioned, damage to the structure during a strong storm is to be expected. But not all damage requires immediate attention. Missing shingles, small leaks, and overflowing gutters do not rate as emergency situations. If you contact a service provider with those problems either during or after a storm, it is highly unlikely they will respond immediately. Those are, after all, issues that can be addressed on a scheduled visit.

As a general rule, immediate attention is needed when the structure is compromised and allows water infiltration. In this instance, the service provider will install a temporary protective covering, such as a tarp, to prevent further interior and structural damage. Permanent roof repair can then be completed at a later date.

When To Expect Service

If you call during a storm, do not expect an immediate response. There’s honestly nothing a crew can do when high winds and heavy rain are raging all around them. In most cases, they must wait until the storm passes before they start making house calls. Depending on the damage and the time of day, the team may either cover the exposed area with a tarp or perform temporary patchwork. They might, for example, use aluminum flashing to cover missing shingles, small holes, and other exposed areas.

Permanent Repairs

When the damage is caused by a fire or a fallen tree, timely roof repair may be impossible. Because both events are likely to cause structural damage, the entire roof may have to be removed and replaced. To determine if complete replacement is required, inspections must be performed on the structure before any work can be done.

How To Proceed

If your phone is still working, you can contact a local contractor and request emergency roof repair, otherwise use the google homepage and send us an email. As we mentioned, they probably won’t show up on your doorstep until the storm passes. You can also report the damage to your insurance provider. This may help expedite the claims process when you submit the estimate for repairs. You should also explore your options once the contractor has completed the initial inspection. Lastly, it is extremely important to document all damage in writing and with photos. This information must be submitted to your insurance provider in a timely manner.

A Word Of Warning

We should also add that attempting any roof repair on your own is an incredibly bad idea. Hundreds of homeowners are seriously injured each year because they think they can fix a minor problem with a little elbow grease. In the end, this dangerous work is best left to the professionals. This goes double when the structure has been compromised and is in need of immediate attention.

Five Reasons To Call A Roofing Contractor ASAP

According to home inspectors, roof issues are among the most common problems they discover in older properties. There are two reasons for this trend. The first is these structures tend to wear out in about twenty years, which is about the same amount of time it takes to raise a family before relocating. The second reason the structure often falls into disrepair is because many homeowners make the mistake of ignoring minor issues. With that in mind, here are five reasons to call a roofing contractor today.

1. Water Leaks

Contrary to popular belief, putting a pot or pan under a leak is not the best way to deal with water intrusion. Far too many homeowners ignore minor leaks because they only occur during a heavy downpour. But the fact is that water intrusion can cause problems, even when it isn’t raining. Because mold and mildew are attracted to moist environments, they may seek out a leak after rainwater resides. Their growth in these areas can not only damage the structure, but they may also put your family’s health at risk. For people with respiratory sensitivities, inhaling mold spores can cause a serious allergic reaction. An experienced contractor can quickly and affordably repair a minor leak. Persistent water intrusion issues, on the other hand, may be a sign that your roof has seen better days and should be replaced in the not-too-distant future.

2. Missing/Damaged Shingles

As sturdy as the structure may be, a roof will not last long without the protection provided by shingles. Depending on the material, shingles have a useful life of twenty or more years. Past that point, shingles may begin to crack, degrade, and fail in vulnerable areas. Because of increased exposure to the sun, shingles on the southern face of the structure often expire before those in other areas. To avoid expensive repair and replacement fees, it’s always a good idea to have your highest level examined by an expert every few years.

3. Worn Flashing

Whenever something protrudes from the roofline, such as a vent stack or chimney, waterproof materials known as flashing are used to protect vulnerable areas from water intrusion. Over time, however, flashing will gradually wear away, leaving these spots unprotected. According to most experts, flashing should be inspected every five years to prevent leaks.

4. Sagging

One sign your structure is nearing the end of its useful life is if it visibly sags in any way. Whether caused by defective materials, improper installation, or age, sagging is both unattractive and potentially dangerous. Always consult a professional roofing contractor if you notice depressions or sunken areas in your roofline.

5. Advanced Age

If your highest level is over twenty years old, odds are it’s nearing retirement. Even if there are no major issues, it may be time to consider replacement. At the very least, you should have the structure examined by an expert every year. In many cases, it may be less expensive to replace the entire upper covering than it is to keep fixing minor problems that will occur with increased frequency in an older home.

An experienced roofing contractor can protect your home and its contents by addressing the aforementioned issues.

Metal Roofing Is Worth the Investment

Metal roofing is a large investment. This material is more expensive than traditional options, such as shingles. It is also, however, a wise investment because it is long-lasting, stylish, and energy efficient. These characteristics make metal, installed by a certified roofing contractor, the best option for homes all over the world.

Valuable Investment

In the long run, you will save money with metal. Other materials require more frequent repairs that offset the more expensive initial investment of metal. For example, asphalt requires re-roofing every 10 to 20 years. With regular maintenance from a trained roofing contractor, no extra services are needed. Furthermore, this material can even lower homeowners insurance bills by up to 35 percent. This product is an investment that will not only protect, but also add value to your home.

Lifespan

A durable metal roof lasts, on average, two to three times longer than traditional options. Replacing this essential component is one of the most expensive repairs a homeowner needs to do to maintain the structural integrity of their home. Non-metal options last, on average, 17 years. You could endure this cost every 17 years or pay for a more durable structure once in your life. Some customers may believe that this choice is more prone to rust, but that is not true. The production process has been engineered to avoid corrosion. Zinc or a combination of zinc and aluminum create a durable coat and a superior product. The lifespan surpasses all other commercial products.

Stylish

Be the envy of the neighborhood with a slate, shingle, shake, tile, or standing seam design. There are colors and designs that will match your aesthetic. Most of these patterns are made to appear similar to more common or classic materials. Most roofing contractors have information about the production process of each design.

Efficiency

Do you want lower utility bills? Metal, no matter the color, reflects heat. This process helps keep heat inside during the summer and also retains heat in the winter. This leads to more money in your pocket. On top of this, many manufacturers have a 25 percent minimum for the recycled content included in the production process. Your new roof will not only be reusing waste, but eventually 100 percent of the material will be recycled. This is, by far, the greenest choice.

Of course, the most important aspect of any repair or renovation project is finding a certified, experienced roofing contractor. Once you find a good match, discuss all the possibilities. Metal just may be the perfect match!
