I have taken my time (more than that..it's been many months) following the installation of my new roof to write a review. George, William and team absolutely 100% delivered. Nice job. Really a great group of people. Fortunate to have found them.

Thank you Signature Roofing!

Working with Signature Roofing was a pleasure as they replaced our old roof. Their cost was the best of the estimates that we received. They let us know via e-mail in the evening what was going on with the job and what would be happening the next day, if anything different. They did an excellent clean-up after the job, also. After the roof installation, we thought we had a leak and Signature was quick to check out the problem. The leak was from another issue and not the roof. We recommend Signature highly.

Signature roofing replaced our roof about 3 years ago. The job was done in a timely manner and the cost was competitive.
Three issues with the job.

1) the addition of wood sheeting and asphalt shingles adds a lot of weight to the roof compared to the previous wood shakes on our 1960 ranch house. There was no caution from Signature to choose thinner and lighter shingles. We chose the triple layer. As a result of the new roof sheet rock has cracked or split in multiple places. There was no warning of this from the roofer and no call back when I called the company about this issue.

2) We have a hip roof and I knew the new roof would be hotter than than the wood shake roof it was replacing. I brought this up to the supervisor or who did the estimate. He said the quantity of O'Hagin vents Signature planned to add would be fine and sufficiently vent the attic. Wrong! We had to add a roof fan even after re-insulating the attic with the highest rated fiberglass insulation. They also did not put an O'Hagin vent in the garage roof so no ventilation there. When I look at our neighbors roofs it appears all have a vent in the garage roof.

3) We recently realized that we could smell kitchen orders in the garage if the range vent had been operating. I climbed up into the loft and found the 6"" vent pipe coming out of the wall from the kitchen completely disconnected from the vertical vent pipe which goes up through the roof.

The roof itself is holding up quite well but I would not recommend Signature Roofing based on our experience.

Great service. Professional and always willing to solve even the most minor issue. Would recommend them without hesitation. Example of a solid local business that goes the extra mile and genuinely takes pride in their work.

I chose Signature Roofing after several friends and neighbors said George and his team were ""The Best.""
Communication from the site visit to completion was beyond my expectations. The estimate was competitive. George, PJ and William responded quickly to every question/concern. Daily updates were greatly appreciated.
The roofing crew were considerate, friendly, efficient and sensitive to neighbors concerns. They cleaned up everyday and did two final sweeps at the end of the project.
All went smoothly and the new roof looks terrific. I highly recommend Signature Roofing.

This is a long overdue review. I would simply like to say that they are great at what they do. Their offer was competitive and communication was as you expected for a ""big"" job. Overall I was happy with the finished product and would not hesitate to recommend them. Keep up the good work!

From the initial request for a quote for a roof on a duplex I own in San Mateo to the completion of the job, Signature Roofing provided exceptional workmanship, as well as, being careful every step of the way to keep me informed of how the job was going. Clean up was perfect even taking into account that two roofs had to be removed. This is the best construction company to do any roof job. I highly recommend Signature without reservation.
