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

Horrible install

After I hires Comfort and their Subs...which they advertise they dont use. I had them remove ¾ of the underlayment because of debris left under it and nails sticking through. Then, I climbed up and checked the underlayment and gave them the ok to proceed with the roof. After many meeting with Comforts fireman as I call them....putting out little fires. They agreed to do another complete tear off and then put another roof on and that one also fsiled....after they only wanted to give me a cred...

Pleased with the new roof!

Pleased with the new roof, job well done, thank you!

Made my old house look new again!!

My roof was in horrible shape, Chris Willoughby from Topper Roofing gave me a great price to make my roof new again. Carlos (the field supervisor) walked me through every issue with the roof by showing me the pictures of the damaged areas before making any repairs. Carlos and crew performed their work in a completely professional manner and left the property spotless. They roof looks amazing.

GREAT LOOK!!

We received a random call about a free roof inspection and thank goodness we made an appointment!! We knew a new roof was needed when we bought our home so we thought why not! Phalisia Lloyd did out inspection and helped us with financing as well. Although it was a little pricier, it has a lifetime warranty and the guys did an amazing install job. We received the roof and gutters in 2 days!! Thank you so much to Phalisia and Zach!!!!

Love the look of the shingles!

We replaced our roof recently as a result of storm damage.

New roof ! Great Job !

Nick and his crew went above and beyond to make sure we were happy with our new roof. They did the job efficiently and timely.

New Roof

Sabrina of KDCO Home Improvement and her team did an outstanding job. They were efficient and hardworking and Sabrina kept me informed from start to finish. They did excellent work and my roof was installed in one day! I am very happy with my new roof.

My new roof

Eason Roofing put a new roof on my house and did an awesome job. I love the choice of tile that I picked out and it looks great on my house.

Safeguard Roofing is a good choice

Safeguard Roofing replaced my roof on 06/16/2026. Very satisfied with the workmanship. A full crew of six arrived at 7 AM and the job was completed by 4 PM. The workers cleaned all the debris from the old roof and carted it away, replace all objects that had to be removed and were very mindful of the gardens around the house. They removed the awning on the roof and replaced it when finished. If you need a professional roofing company make Safeguard roofing your choice.

Highly recommend them for roofing work!

Great roof!!!...

I replaced my roof a few months back. I love the quality of materials and the look of my new roof.

Great features

Roof was replaced due to April 2026 hail storm. Workers were efficient, kept things cleaned around the yard, and completed the re-roof in one day.

Installers did a great job. Time will tell about the shingle

We contracted with "Fields Above Roofing" to replace our roof shingles. They did a quality, professional job. Time will tell as to whether the shingles they used are any better than the "30-year singles" they replaced, which lasted 13 years, and were facing AWAY from the sun.

Good job!

I have replaced my roof, about a month ago. It’s been exposed to some very hard rain and also some very hot sunny days. It’s looking great and no leaking at skylights, or water from the attic. Off to a good start for a long life on my now very good looking roof. The warranty stands behind my statement!

New roof on the block

Hated my old roof!!! Thank you for such an upgrade. Love the color choice I made

Big Bear is the Best

They were totally professional, on time, efficient, and their work could not have been better. I could not be happier about what they did for us.

Slate to shingle

I have storm damage to our 1862 slate roof. We chose Timberline HDZ for replacement. It has great durability and astetics look to replace our slate.

Gaf Timberline HDZ - steep slope/ Overall appearance/ slate

Repels moss build up/ embers from fires, especailly in Hope BC areas where I am surrounded by large trees, bushes, etc. and fires a strong possibility due to climate change.

Quality

Shingle thickness was consistent and granules embedded very well.once sun did it’s thing the shingles laid flat as well in the valley’s.

Beautiful Look and Great Quality

The shingles look fantastic on our home. The color and texture add great curb appeal, and the quality feels excellent. Installation went smoothly, and we’re very happy with the final result. Highly recommend!
