Roofing Warranties - Valuable or Sales Tool?
[Click to enlarge any image]
Above is a worn-out asphalt shingle roof. This roof is shot, but has actually worn normally and is more than 20 years old. But if a roof wears out, or suffers damage that is likely to reduce its remaining life to less than the anticipated life or warranty period, a warranty claim might be in order.
Don't have high hopes: if the roof was not properly installed the shingle warranty may be void. Other roofing products that have known premature failure problems are also discussed here.
Shingle warranties run from 20 to over
50 years. Although products with longer warranties are usually
of higher quality, in some cases, the longer warranties
are more of a marketing strategy than an accurate predictor
of shingle life.
While the specific terms of the warranty are
important, more important is the manufacturer’s reputation
for warranty service in the local area. All manufacturers
retain the right to void the warranty if installation instructions
are not closely followed, and they can often find a
way to avoid honoring a claim if so inclined.
Background about roof warranties:
Asphalt roof shingles are the most common covering used on residential properties in North America.
Early shingles were made by saturating rag-felts
with asphalt and by coating each side of the saturated felt with an asphalt-mineral filler-coat, covering the top surface of the shingle with
mineral granules (sunlight and weather resistance) and coating the bottom surface with a material to prevent shingles from sticking together in storage or shipment.
Beginning in the 1940's the felt mat was changed to a zero
rag-content using wood fibers and cellulose (newspaper). More recently many manufacturers began producing shingles using a fiberglass mat to replace the felt. The fiberglass mat was thought to have good tear resistance, possibly
slightly better fire resistance, and as the mat was generally thinner than the felt mat, we believe that there were also economic advantages for both the
manufacturer (less asphalt used in the mat) and the roofing installer (lighter material, easier to install).
In certain instances specific roofing products have shown common early failure, failing in a characteristic pattern which is easily identified (such
as the thermal splitting defect. Some manufacturers offer limited warranty coverage of their product. Many roofers also guarantee their work to be free from leaks, but usually for a time period substantially shorter than the manufacturer's rated life of the roof material.
In cases which we've handled in the 1990's to about 2004 and involving thermal splitting or
tearing of fiberglass-based asphalt shingles, some manufacturers (such as GAF) offer a limited product warranty.
Following a fairly involved claims procedure requiring documentation, photographs, and a sample of damaged material the manufacturer may elect to warrant the roofing material on a pro-rated basis
depending on the age of the roof and its warranted life. Sometimes the manufacturer's warranty covers only material cost, not installation cost (labor, demolition, removal of old materials) unless the roofing contractor chooses to extend such coverage.
The cost of roofing material is not the main ingredient in roofing cost. Labor and possibly disposal of old roofing material are significant costs.
Out of concern for future roof life, some roofers are reluctant to install new roofing atop failed material even where additional layers of roofing are permitted by local codes.
Some homeowners are reluctant to install as new roofing the same product which failed early in the first place. Manufacturers might have changed the
formulation of the product to improve durability, but they are understandably reluctant to say so, out of concern for increasing product liability.
assurance from the manufacturer that a product which failed early has been modified to correct the problem, we advise our clients to consider using
alternative products with design and performance expectations having a better track record.
Best Practices Guide to Residential Construction lists several key issues to consider in evaluating a roof shingle warranty:
Is the warranty prorated from the date of installation,
or is there an introductory term of 5 to 10 years when
the full value can be recovered?
How long are warranties valid against wind damage,
algae growth, or other types of damage?
Does the warranty cover a portion of the labor costs of
tear-off, disposal, and installation, or does it cover
Is the warranty transferable?
Perhaps most importantly, does the manufacturer have
a strong reputation for warranty service in the local
When buying clay roof tiles, look for at least a 50-year warranty on both durability and fading.

Question: roof manufacturer offers very limited settlement on asphalt shingles with granule loss
2016/09/08 Spencer Rafferty said:
I have a roof of 12yrs with 25yr shingles on it, I noticed significant granule loss on 90% of whole roof on the single layer part of arc. shingles. I contacted manufacturer and they only offered 384.00, then I contacted local representative and he's only offering about 1,700.
Now I am a Home Inspector and know from experience this is a manufacturers defect because its on 90% of roof and certain parts of each shingle. Problem is I feel they should honor their warranty of full replacement, so how do I go about getting independent testing of shingles to determine if it was manufacturers defect to go after company ?? Any help would be appreciated !
Thanks for the important roof shingle warranty question, Spencer. Now it's time for a dose of painful reality. What follows is my OPINION.
Roof shingle warranties vary, and you don't mention the brand and model of your roof shingles so we don't know what your warranty promised. Usually shingle warranties, even "lifetime" ones, are actually quite limited.
IF the manufacturer agrees at all that the product is defective, you'd expect recover a portion of the shingle material cost, pro-rated based on the percent of roof life promised vs. delivered.When the roof has lost granules such that its remaining life is likely to be reduced and when we are now at 1/2 of the roof's rated life, but the roof is not yet leaking, the manufacturer is going to argue that the roof has not yet "failed" - it's not leaking. So they are re-adjusting the 50% of shingle material cost to a smaller sum which is the manufacturer's own opinion of the amount of reduction from the 25-year life that has been caused by the roof's deterioration. They may not enjoy explaining that to you but that's probably the rationale behind the pathetic warranty offering.
The manufacturer will also adjust the warranty coverage for a roof based on their own observation of installation defects including virtually anything that did not completely follow the manufacturer's installation instructions regarding product selection, underlayment, nailing schedule, condition of the roof deck, flashing details, roof ventilation details and perhaps other conditions (such as mechanical damage from ice dams).
The cost of a roof leak in damaged building insulation, wiring, finish materials, drywall, and potentially mold clean-up can also be a significant cost that won't be covered by roof warranty even if the roof is actually leaking.
The labor to install roof shingles is normally a much greater cost than the materials, a third fact that makes roof shingle warranties of only very limited value.
What we learn from this is that product warranties are more of a marketing feature than something intended to actually protect the consumer. Roof shingle warranties may tell us something about the comparable expected life of different roof products but they're not particularly valuable as insurance against early roof leaks.
See WARRANTIES for ROOF SHINGLES - at inspectapedia.com/roof/Roof_Warranties.php for a series of articles about roof warranties and collecting on them.
In corresponding with readers about this topic for decades now I've seen that just what the roof manufacturer or roof installer offer in settlement varies considerably depending in part on how much trouble the consumer is making and how persistent is the consumer in pressing a claim as well as on the difference between large commercial jobs and residential roof jobs.
Asphalt shingle test labs offer product testing services that can explain why a shingle product is failing or appears defective, such as loss of volatiles, over-heating during manufacture, or other manufacturing or service life defects. You could try asking one of these labs to test representative samples of your roof; you'd need to photo-document the whole roof, document the product, its installation details, and other information, then cut samples, patch the cut area, and send your samples to a test lab.
I would of course be interested in what the lab tells you - we'd all benefit from that if your case were adequately documented. But I warn that YOU are not an important customer to the roof shingle test lab. The roofing manufacturers may use independent asphalt shingle test labs to monitor and assess their own manufacturing process. They, the manufacturers, are far more important customers to the lab than you. Therefore you might find some reluctance on the part of test labs to help you prepare material that will in turn be used to annoy their main client.
Do keep me posted, and do use the page top or bottom CONTACT link to send me sharp photos of the whole roof, varying conditions by roof slope, and close-ups of granule loss on shingle surfaces as well as of the lost -granules that you probably see in your gutters or on the ground.

How To Identify Cal-Shake Shakes (Cal-Shake, Cal-Slate, Cal-Clay Roofing)
Cal-Shake Shakes are a fiber cement roofing product made to look like wood shakes. Cal-Shake Inc. also manufactured Cal-Slate and Cal-Clay, both of which are included in this settlement. Cal-Shake Shakes were manufactured as shakes and distributed between 1980 and 1995. Please review the information below to see if you have Cal-Shake Shakes installed on your roof. If you take the steps suggested below and are still having trouble determining whether you have a Cal-Shake Shake Roof, please call 1-866-844-0600. Here is a Cal_Shake Claims Form.
Ask the roofer who installed your roof.
Review any invoices, statements, or warranty information that the roofer provided you when the roof was installed or may have been provided to you at the time of purchase by the previous owners of the home.
Review any home-inspection report you may have received upon purchase of your house, which may contain information on the type of roof installed.
Look for broken shakes to see whether the logo "Cal-Shake" is embossed on the top half of the shake.
You do not have a Cal-Shake Shake Roof if:
The shakes on your roof are made of wood
The cement composite shakes on your roof were manufactured by:
Monier, Owens Corning
To be a member of the New Cal-Shake Settlement Class, your Cal-Shake roof must have been manufactured between February 1, 1986 and March 31, 1995. The date of manufacture is not marked on the Shake, but if your roof was installed within this period you are probably a member of the New Cal-Shake Settlement Class. People whose roofs were installed very early in this time period might have Old Cal-Shake roofs.

Watch out: be sure that your roof shingle warranty claim are filed with the roofing manufacturer following the company's procedures and within the time limits provided by the roofing manufacturer's warranty. Otherwise you can expect a response such as this one sent to us by reader Nancy Lescarbeau:
At the end of June 2009, I tore off and replaced the shingles on my roof and opened a claim to CertainTeed. I took 40 some pictures and typed up detailed information for each. I sent in a sample of the bad shingles like Certain Teed asked on their roof warranty claims form. But I never sent in the claim till the winter months, and I received the answer back that states:
"....The warranty may be enforced only by the original homeowner/consumer who purchased the shingles or by an individual who had transferred the warranty during the allowable time period. " (which is two years) ".. CertainTeed Corporation, therefore, is excluded from any liability or obligations to you under the terms of the warranty since you are not the original homeowner/consumer..."
The original owner installed the new CertainTeed roof two years before selling the home to me in 1999. So, even if he had transferred the roof shingle warrantee, the time limit still exceeded CertainTeed's transfer warranty provisions. At the time of my roofing shingle claim (or the claim I wanted to submit), my roof was 12 years old not 10.
And not covered by a warranty at all.

Whiting IN 46394
Globe Shingle appears to have disappeared from the roofing world before 2005; we have not had reports of successful warranty claims since that time; however if your roofer knowingly installed Globe™ shingles after the company's shingle failure was well known, you might ask him/her what he/she is willing offer when re-roofing is needed. Some contractors will re-roof for the cost of the materials alone if they accept responsibility for the Globe shingle roof failure. Also if the shingles were installed on a new home, depending on the U.S. state where the home is located, a new home warranty provision may apply.
Globe Building Materials, Inc. was manufacturer of asphalt and laminated roofing shingles from about 1934 to 2001. In 2000 the company suffered financial difficulties and in January of 2001, Globe filed for Chapter 11 bankruptcy. In April 2001, Globe filed Chapter 7 bankruptcy. The lender was left with a large inventory of finished shingles as well as other assets and liabilities.
ARG, a company that assists corporations in financial trouble, assisted in closing out the bankruptcy, including managing the sale of more than 750,000 bundles (250,000 squares - a square is 100 sq. ft. of coverage) of Globe shingles. However before, during, and after that time we and other researchers heard recurrent reports of Globe shingle defects and early product failures. While ARG considers the Globe shingle merchandising a financial success, it may be that that activity also dates the last sales of Globe roofing shingles to roughly 2001.

Question: looking for independent shingle testing lab

Need an independent lab to test poor shingle performance. The manufacturer may not say anything wrong with their prodeuct. Where can I send the shigles samples for performance.
(Apr 21, 2014) Diane said:
Tried to go to the GAF informtion and the link is broken. Also tried calling the 800.414.4370 number and got a recording unrelated to GAF.
Still looking for information on the GAF Timberline/Royal Sovereign settlement.
Question: GAF Sentinel Shingles failed after 8 years
(May 30, 2014) Charlene said:
GAF Sentinel shingles failed within 8 years. However the warranty only covers materials if you don't notify them that the shingles are defective within 3 years of installation.
How misleading is this? Who's going to peel back the shingles to determine if they are defective within 3 years?
Charlene, I don't think that the warranty expects anyone to remove shingles to look for defects. The defect should appear on the exposed shingle surfaces or should show up as a roof leak.
