My Certainteed Sealdon 25 year 3 tab shingles I installed in 2003, photo
as it was in 2003, note the continuous ridge vents, there are many eave vents and 3 gable vents as well, there is also a power attic fan.
By 2007-2008 these shingles started looking like this in the areas where direct sun hit, at first I thought maybe it was ice damage... boy was I wrong!
By 2012 it was clear the shingles were severely failing, so I did a google search and found a Certainteed class-action lawsuit, that was when I learned my 25 year shingles were DEFECTIVE. I joined the class and did the paperwork, photos, provided some receipts for the materials that I kept, and sent them one complete shingle as required, here's what the shingles all looked like in 2012, it's easy to see the green granules were now coming completely off in large chunks:
Here's what MY Certainteed 25 year warantee 3 tab shingles looked like last week when I set about replacing it, I installed this roof in 2003;
After I submitted my class-action claim and documentation, I received a check for just about $1200, I used about 16 squares, the green was Sealdon 25 the grey/white I also used was their Custom 30 and even these are failing but not as badly.
The saving grace of why this roof does not leak is due to my using Tamko Moisture guard over the entire deck, even with the 3 tab nail heads all exposed due to curling, the Tamko had sealed around the nails and there are no leaks!
So what's a homeowner to do now? after spending weeks researching, reading reviews and more, I came to the conclusion there isn't one single asphalt shingle roof worth buying, it doesn't matter if it's "laminated" "thicker" what brand makes it, it's all the same JUNK. Every one of the common big manufacturers who sell to your local building supply houses and roofers whether it's Certainteed, Owens-Corning, whatever- have numerous complaints and lawsuits against them for defective products, failing to honor warrantees, giving homeowners the runaround, offering them a lousy amount of money on a claim and stating they completed their warrantee. I've read of people who paid $8,000 to $12,000 for a new roof only to get a check for barely $1,000 for the "warrantee" payoff just a few years later!
So here's what I decided to do, since it's late summer now and I don't have the time/money right now to entirely re-roof my house, I decided to tear off the West slope shown in the first photo which is now down to the crappy recycled PAPER Certainteed used to make these shingles with! And re-shingle it with a different brand and color of 3 tab (3 squares worth) since no one around here even carries 3 tab any more, I had to sort of "special order it" this will get me through the winter water tight, but come next spring I will be installing an aluminum permalock shingle roof.
This stuff comes with a lifetime NON prorated warrantee, it's also a transferrable warrantee. I have thus far not found even one complaint about the product itself and the company making it has been in business since 1948, I only found some complaints about installers of it.
As of today it costs about $225 a square, roughly double that of the cheaply made asphalt junk. It can be installed right over the 3 tab provided the shingles are not all curled up of course, so I won't need to do a tearoff.
The bright bulbs at Certainteed created a "green" product that was supposed to break down quicker in the landfill, instead it started breaking down on my roof just 4 years after it was installed!
