Yes my roof is only 12 years old. Summit

shingles by gp were defective. Do you have a rep to talk to?

Hi, I have a 12 year old GP roof that I thought had hail damage. A reputable roofer said it was defective shingles. Had any luck getting response on your roof? Thanks!

My roof is approx. 16-years old &, same as "GP Summit" author, I found out about widespread blistering following a 'hail inpsection' by my insurance co. (i.e., no hail damage, but blistering throughout roof).

By working through my home builder, & his supplier, I was put in contact w/GP Roofing Claims: Charlotte Williams, 1 800 445-0952.

If your shingles were purchased prior to Jun '94 then you need to talk to Raymond at (404) 652-3748, who will send you a claim package...which is a 'bear' to complete.

If you bought after 1994 and have a claim, per their 800 number, you are to call Atlas Roofing at 1-800-478-0258 for a claim package. Mine is on the way.

Do they have a fiberglass or orgaic matting.

In the manufacturing process cellulose mats can retain moister. Sandwiched in hot asphalt can encapsulate the moister and about ten years on a roof surface the moister can migrate up though the shingle and cause blisters. Those blisters pop, next rain every blister can hold a drop on water that can migrate back down to the mat and the whole process starts again in mass form. Usually the south/west side of the home is affected first. My recommendation is to use any manufacture you would like, but make sure to they use a fiberglass mat and don’t forget to use a product that is (A/R) algae resistant.

Also a foot note; Color plays one of the most import parts of a composition roofs life expectancy and in my opinion, most manufactures oversell there warranties.

My personal observations in the southern states are that regardless of whether you purchase 20,30,40,50 or LifeTime warranty shingles:

22-27yrs. White

20-24yrs. Tans, Light Tones

18-22yrs. Grays, Gray/Blues, Browns

16-20yrs. Blacks

Quality Roofing

i purchased a home in 05 that was built in 1996 using gp shingles. i think the brand is premium 25. luckily i have 3 bags left from the original installation.

after finding a leak in my sunroom, i had several roofing contractors come by and they photographed many shingles with cracks, holes, etc and i have to replace this roof along with the rest of my cape as the same situation exists.

glad i found this site for the phone numbers.

i assume that the warranty was transferable as i have no receipts etc

anyone know about their warranty?

now if course i have to take a crash course in roofing 101.

i've narrowed my choices to certainteeds solaris product or gaf's cool product as they both qualify for the tax rebate

See my 11/02/09 e-m -- "GP Summit cont'd" -- which indicated that I had taken the time to complete & submit a claim package.

I got a response to my package last week: 'No dice.'

GP denied my claim, stating that, in their opinion, my "ventilation is not properly balanced and additional upper ventilation may be necessary."

What now? I don't know. Anyone have any experience / ideas on how to refute GP's opinion on ventilation shortcomings?

I`ve delt with a few venting related denials by the manufacturer of a couple brands. ( independent quality inspector )

The proper way to vent the product is listed on the bag of shingles specifically to pass the responsability to the installer. Most offer an exclusive warantee to installers that have registered and passes manufacturer testing for proper installation and venting of their products. I have this title with GAF and Certinteed.

Any other venting issues are soly the responsability of the installer or homeowner. It`s important to be clear on issues before work on your home begins or signing a contract.

Mold is a ventilation issue all companies want to be exempt of !!

Thanks for the response / input. The problem is that A) I don't have the bag that the shingles came in (since they were installed in '93, I bought the home in '03, & original owner did not leave bag / extra shingles behind), & B) GP's denial of my claim included a copy of the "Limited Warranty," & ALL it says on the subject is, "Warranty Limitations...include...inadequate attic ventilation..."

As I mentioned in my previous post -- Feb 1, 2010 -- GP's denial of my claim states, "...it is [GP's] opinion that your ventilation is not properly balanced and additional upper ventilation may be necessary..."

Is that all that's required of them to deny my claim? Opinion? Where is proper balancing defined? MAY be necessary?

No, It sounds like their test showed excessive heat damage, venting codes vary State to State. You can further demonstrate by asking to meet with a GP rep. Have your attic confirmed by an HVAC co. before you meet.
