12'x12' SHED ROOF

JUNIOR AND JOSH DID A PROFESSIONAL JOB ON FIXING AND REPLACING MY LARGE SHED! I WOULD RECOMEND THEM AND HAVE TO MY FRIENDS AND NEIGHBORS!!!

Beautiful looking roof which gives a nice curb appeal.

I replaced my roof with Lockhart Roofing and was very please with the job done and the clean up afterwards.

Great product and contractor

I replaced my roof with the new GAF product and could not be happier with the product and it's curb appeal.

Great looking roof!

We replaced our roof a few weeks ago and it looks amazing!

Exceeded Our Expectations

We replaced our roof earlier this year with a GAF product. Our previous roof was defective and the roof was replaced under a warranty claim with different manufacturer. Our roofing contractor, Ridgeline Construction highly recommended GAF products. So far, we are very pleased with our new roof and Ridgeline Construction. Ridgeline was very professional through very effective communications and high quality workmanship. We would highly recommend GAF and Ridgeline Construction to anyone needing...

Looks beautiful and durable. M2J LLC did an amazing job!

I replaced my roof late June 2026. I’m so happy I did. Lots of peace of mind.

Great architecture style roof tiles

I replaced my roof 2 weeks ago. I am very pleased with the look and especially the quality of materials the new roof is made of.

Best possible experience for getting my roof replaced!

The service I received from the installer and crew was simply exceptional. He provided clear communication that allowed me to understand my options and just what I was investing in. He made me feel very comfortable with the quality and value I was receiving by choosing a GAF roof. Installation was fast and unobtrusive, and my new roof looks beautiful. I will definitely recommend this installer and the GAF system to everyone who needs a roof!

HIghly recommended

Tremendous work! Highly recommended!!!!!!!!!!!!!!!

Looks Great!

Our old roof was the 3-tab type shingles and was over 25 years old. The new Timberline HDZ shingles make the house look so much better. All materials needed to replace our shingles were GAF, rom underlayment to roof venting. All are very good quality. I'm very happy with our new roof.

Great Job!

The company is straightforward and offers an excellent price.

Couldn't have made a better choice!

Product was excellent as where Knox construction. They arrived on time, completed the job and did a very thorough clean up. The roof looks excellent, great product.

I love my new roof!

I replaced my roof last week. We've lost shingles every year with a competitor's product, and I'm really looking forward to that not happening again. I'm very impressed with the GAF shingles and the crew who installed them.

Beautiful roof! Quality materials! Professional job!

I replaced my roof a month ago and am so pleased. Severe storms have hit since then and its comforting to know my home and garage are protected! Live in a windy area and its great knowing my roof is so secure! And it looks great too!

I hope to give it 5 stars in the future

Since only time will tell about the product overall, I gave it a 4-star review. I replaced the roof last year. A storm blew off a section of our shingles. I found a contractor that patched the repair until he could come back and replace the whole roof. I liked their were several colors to choose from and the product felt more durable than the shingles we already had and the 50 year warranty. I also think the product is only as good as the contractor who installed it. I built a good relationsh...

Great product for my roof

John Fincher from Exteriors Plus was great to work with! He brought us several shingle samples and we loved the Pewter Gray. Our roof looks great and we love the color!

Tracys new roof

The men were great, roof looks very nice and cleanup outstanding!

Fantastic!

I absolutely love my roof. The process was super easy. Lots of great communication, cruise were on time, and I was always kept informed of what was going on including pictures when they took the roof up to show how I desperately really needed a new roof. I’m so grateful to not have to think about a leak on a roof and I don’t have to think about shingles flying off during wind storms. Cleanup was awesome, and they even brought their own porta potty for their workers. Overall best experience so fa...

Great service

GAF Timberline HD a great shingle

I replaced my roof 3 weeks ago and the shingles looked great and sealed quickly. A rain storm hit the next week and was glad I had replaced the shingles. Outstanding product.
