Tamko Informative - Tamko Heritage 40 Year Shingles
ST. LOUIS, MISSOURI -- In November of 1999 We re-roofed our 20 year old home with Tamko Heritage 40 year shingles because our homes roof was old and the shingles had lived out their life. We expected 40 years. In October of 2007 a Roofer came to our house because we were adding on and needed an estimate to continue with Tamko. This roofer discovered that our 9 year old roof was blistering. We called Tamko. They told us what to do. We did.
They said it would be 12 weeks for them to do the necessary test. With many many phone calls 5 and a half months later they finally ruled against us saying we had improper ventilation. Now another roofer and a builder said that was a bunch of BUNK and they were giving us the runaround.
When I called in disagreement I was hung up on when I said I would have to talk to an attorney.
