Roofing Services in Hollister, Gilroy & the Bay Area
A roof that's past its life expectancy is one of those things that doesn't get better with time. SGM Builders handles roofing as part of our full general contracting services re-roofs, repairs, and new roof installations for residential homes throughout Hollister, Gilroy, Morgan Hill, and the greater Bay Area.
Re-Roofing & Full Roof Replacement
If your roof is 20+ years old, has multiple layers of shingles, or is showing widespread wear, a full re-roof is usually the right call. Patch repairs on an old roof can slow down the inevitable, but they don’t stop it.
A full re-roof involves removing the existing material down to the sheathing, inspecting and repairing any damaged decking, installing new underlayment, and applying the new roofing material. We pull permits, schedule the inspection, and make sure everything is documented important for insurance and for any future sale of the home.
Timeline for a standard re-roof on a single-family home: 1 to 3 days for the installation. The full process including permits is typically 1 to 2 weeks.
Roof Repairs
Storm damage, missing shingles, flashing failures around chimneys or vents, leaks around skylights — we diagnose and repair. Some repairs are straightforward. Others require more investigation to find where water is actually entering versus where it’s showing up inside the house.
We’ll give you an honest assessment: if a repair makes sense, we’ll do the repair. If the roof is close to the end of its life and a repair is just buying a year or two, we’ll tell you that too.
Roofing Materials
Asphalt Shingle. The most common residential roofing material in California. Cost-effective, good performance, available in a wide range of colors.
Tile. Clay and concrete tile are common throughout the Bay Area and Central Valley. Longer lifespan than shingle, higher upfront cost. Works well with Spanish-style and Mediterranean architecture.
What to Expect From a Roofing Estimate
When we come out, we’ll get on the roof and look not just assess from the ground. We check the decking, the flashing, the condition of the valleys, and the gutters. After the inspection you’ll have a clear picture of what needs to happen and what it costs.
We don’t use high-pressure tactics. If your roof has three good years left, we’ll tell you. If it needs to be replaced this season, we’ll explain why.

How do I know if I need a new roof or just a repair?
If your roof is less than 15 years old and the damage is localized a few missing shingles, a small leak around a pipe boot repair is usually the right call. If the roof is 20+ years old, showing widespread granule loss, curling shingles, or multiple leak points, a full re-roof is typically more cost-effective than ongoing patch work. We’ll assess your roof honestly and explain what we recommend and why.
How long does a re-roof take?
Most residential re-roofs in Hollister and Gilroy take 2 to 5 days depending on the size of the home and the roofing material. Tile roofs take longer than shingle due to the weight and installation process. We work efficiently and keep disruption to a minimum.
Do I need a permit for a new roof?
In most cities in our service area, yes. A re-roofing permit is generally required and is relatively straightforward to obtain. SGM Builders handles the permit for you as part of the project.
Can you install solar-ready roofing?
Yes. If you’re planning to add solar panels in the future, we can install roofing with that in mind using compatible materials and ensuring the structure supports the additional weight.
