One small repair or a full tear-off, every job starts the same way: we look at the roof in person and put our recommendation in writing.
Here's how we tell the difference. If you're not sure which side your roof is on, start with an inspection.
Most repairs start small: a leak after a storm, a few missing shingles, flashing that's pulled loose. Caught early, they stay small. Left alone, water reaches the decking and the ceiling below.
When a roof is past the point of patching, we'll tell you, and walk you through materials, timeline and cost before you commit to anything.
Not sure what your roof needs? An inspection tells you whether a repair will hold or it's time to replace.

Real reviews from GM Roofing customers on Yelp.
Giovanni was extremely communicative, was very fast in his response and he and his crew did a great job. We had a leak from pigeon clutter under our solar panels that meant GM had to coordinate a solar contractor to do the removal and reinstall. All went off seamlessly and he also pigeon proofed everything so we can avoid this in the future. They earned a customer for life. Thanks GM!
We cannot recommend Giovanni and his team highly enough. He came the next day to give us his bid, was prepared and able to answer all our questions. His communication was excellent and transparent throughout the process. He shared photos during the work each day to show their progress and at the end shared full documentation including a drone video! The workers were respectful and hardworking and always on time.
Giovanni and his team were amazing. They went well above my expectations. He gave me a very reasonable quote and was totally up front, didn't try to upsell any services. He provided quality pictures of all work before and after, and even had drone footage. They showed up on time and completed the work as promised. I highly recommend GM Roofing.
I recently had a large amount of roof repair to my cement tile roof along with some gutter repair. Giovanni and his crew did excellent work. He was always punctual, friendly, respectful and knowledgeable, and his pricing was very reasonable. The clean up after the project was also outstandingly good. I would hire them again.
GM Roofing easily scores 5 stars, and deserves more. From beginning to end of our roof replacement project, Giovanni was nothing but professional, kind, communicative, punctual, attentive, and a pleasure to interact with. His pricing is more than competitive. We would not hesitate to hire GM Roofing again for any and every roof-related project.

Repair usually makes sense when damage is limited to one area and the rest of the roof is in good shape. Replacement makes more sense when repairs keep coming, damage is spread across the roof or the decking underneath is failing. We inspect the roof in person and give you our recommendation in writing.
Price depends on the roof's size and pitch, the material, how many layers come off, decking repairs and permits. We don't quote from the street or over the phone. After an inspection you get a free written estimate with the full scope and price.
Many single-family shingle replacements take a few days on site. Tile, larger homes, decking repairs and weather can add time. Your estimate includes a timeline for your roof.
In California, reroofing generally requires a building permit from your city or county, and the work is inspected. We'll go over what applies to your property with your estimate.
Tile sheds most of the water, but the underlayment beneath it keeps it out of the house. Years of Sacramento heat can dry that layer out and crack it even when the tile on top looks perfect. Often the tile can be lifted, the underlayment replaced and the original tile reset.
