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

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!

Great Team

Just had my roof replaced this week. Couldn't be happier. The team at Summit Home Improvements when awesome, especially Javier!

Roof Replacement after Hail Damage

So far, the product is awesome. Looks great, was installed quickly but accurately by the Action Exteriors team.

Quality product & expert installation

I replaced this roof in early April 2026 and so far I am extremely pleased with the quality of the product and the installation as well on a roof that was fairly difficult to replace. The silver pledge warranty gives me confidence that this roof will sustain itself for the 50 years in which it is under warranty

I've always known it's the best.

When my contractor recommended GAF Timberline shingles, there was no need to consider options. I was already aware of them and that they are considered the best shingles for a home. Now that my roof replacement is completed, I have some peace of mind as well as a warranty standing behind the product.

They look great

Our old roof was 20 years old, it was at the end of its product lifecycle. Our roofing contractor came in with his best shingle & best price the shingle was GAF when compared to the other 2 contractors shingles that gave us estimates, the GAF shingle was just a better looking & heavier shingle than the other 2 contractors shingles.

Long lasting

I love the color and was easy to work with.

Love my new Roof!

Replaced my roof with GAF shingles and I’m loving my new roof! With GAF 25 year workmanship and 50 year product warranty the decision was a no brainer. Highly recommend GAF for those looking for a new roof !

Bodan roofing was exceptional

The Bodan roofing crew was professional, capable and hard working. They quickly took charge of issues as they presented and did not triumphed over all challenges. A+ service. They will get many referrals from me. And your shingles look great.

Great Job

It was a pleasure doing business with Star Roofing. Their work is excellent and they did a great job. I would highly recommend them. They will explain everything to you and answer any questions. Please reach out to them for a quote. You won’t be sorry.

Roof Replacement

I replaced my roof and Dan Farley Roofing they did an excellent job. They were fast, friendly, on time and had excellent workmanship. They are very professional and responsible. We also did not have to wait long for the job to be scheduled and completed on a large, complicated roof. - Thanks to Dan Farley Roofing for doing a fantastic job.
