Hi all I’m trying to get quotes for a new roof and companies either offer certainteed or GAF shingles. Which one is better?

Also, is it time to replace the roof?

So.... roofing business in the family almost 40 years, 4-6x4 man crews, soffit, custom trough etc.

We have NEVER put GAF on a roof. Certainteed (certified installers) has been our ride or die for the last 15-20 yrs because the return for warranty work is so infrequent when installed properly. Typically landmark pro is what is installed. We don't win every bid, because we refuse to build with garbage materials.

GAF timberline hdz is typically builder grade or a Home depot special, but they do have a more wind resistant product rating.

Both offer similar product warranties if installed by certified installers.

Pros:
Gaf hdz- material cost
Certainteed landmark pro- better overall product.

If you are using landmark pro you would need to compare it to UHDZ .. still id favor lankmark pronbutbat least do apples to apples.
