Ratings & Reviews for GAF Timberline HDZ Biscayne Blue Algae Resistant Architectural Roof Shingles ( 33.33-sq ft per Bundle )

Great product

I recently replaced my roof and I can already tell the difference in protection from the heat per the reduced temperature in my attic. It also looks great. A big thanks to Texan Roofing of Houston!

Love my new roof!

I replaced my roof with GAF-Timberline HDZ shingles. It looks great and Thompson Roofing in Madison, Al provided excellent service during the installation.

Looks great , I love the way the product is engineered.

I just replace my roof after moving into a new home 20 years ago. I couldn’t be more pleased with the look and the assurance that my home is protected.

Excellent roofing experience

Pujols was a fabulous company to use to redo our roof. We had no idea that what was under the current shingles was a very old and barely a roof any longer. They were so clear in communicating what they were seeing, and helped us navigate from there. Now I rest easy knowing the roof is tight!

Great Replacement Roof

We replaced our roof several months ago. Very pleased with the work completed by the contractor and the roofing materials from GAF. The roof looks sharp and is a great improvement to our home.

Thorough process!

Big Bear not only explained everything, they kept up with the process. The new roof looks great!

Home Value Renovation Inc replaced our roof and gutters. They did an awesome job. There pricing was comparable to the other 2 quotes we received. Home Value Renovation Inc was highly recommended by friends and they did not disappoint.

Satisfied Customer

Just replaced room and workers and product looks great.

Looks nice.

So far all is good. They have only been on for a couple weeks. It was done quickly and they picked up well behind themselves.

Roof replacement

Had my roof done yesterday by Holencik. Project Mgr Ali and his team did a great job. Very professional and worked straight through until the job was done. Clean up was exceptional. I’ve recommended Holencik to 3 friends through my Facebook post. Would definitely use them again.
