Quality Product and Installation.
Would RecommendI replaced my roof at the end of September 2026 and very happy with the product and the smooth installation by Tony Balsamo Contractor Inc.

Perfect!
We replaced with same brand but much better quality. Previous roof only lasted 13 years. GAF, but owner possibly put on a fix before selling. We removed, upgraded, but chose GAF because our installer carried and highly recommended. Would have went with Owens Corning had they offered. Looks great, but exactly like old roof. Only time will tell how well they hold up.
