Roofing Services

Your roof is the first line of defense for everything underneath it — your family, your belongings, and the structural integrity of your entire home. When it fails, nothing else matters. At Keystone Building Services, we deliver complete roofing services across Sacramento and the surrounding area, including full roof replacements, targeted repairs, storm damage assessment, and preventive inspections that catch problems before they turn into emergencies.

We install asphalt shingle, concrete and clay tile, and standing seam metal roofing systems. Every project starts with an honest assessment of your existing roof. If a repair will solve the problem and buy you another decade of reliable service, we will tell you that. If the underlayment is shot and patching is just delaying the inevitable, we will tell you that too. Owner Gerardo Diaz has over 11 years of hands-on construction experience and a code-first approach — which means the recommendation you get is based on what your roof actually needs, not what generates the biggest invoice.

As a licensed general contractor and licensed electrician, Gerardo Diaz brings a level of building knowledge that most roofing-only companies simply do not have. Roofing is not just about shingles — it is about flashing details around vents and chimneys, proper underlayment and waterproofing, valley construction that channels water instead of trapping it, and ventilation that prevents moisture buildup in your attic. We handle every layer of the system, not just the surface you can see from the street.
