What Ontario Customers Say
"They replaced all our gutters along with the roof. Seamless aluminum, properly pitched. Water actually drains into the downspouts now instead of overflowing at every seam. Night and day difference."
"Our flat roof on the garage had been patched five times by other companies. San Joaquin Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."
Why Ontario Residents Choose San Joaquin Roofing & Maintenance
Storm Damage Specialists
Hail, wind, and monsoon damage are common in CA. Our team includes HAAG Certified inspectors who document damage the way adjusters expect it. We handle the entire insurance claim process so you don't have to.
Free Inspections & Honest Estimates
We don't charge for inspections and we don't pad estimates. If your Ontario roof needs a repair, we'll tell you. If it needs a replacement, we'll explain exactly why. No high-pressure sales, no scare tactics.
No Subcontractors
Every Ontario roof is installed by our own trained crews, not subcontractors pulled from a labor pool. That means consistent quality, accountability, and a crew that knows our standards from the first nail to the last drip edge.
19+ Years of Experience
We've been installing and repairing roofs for over 19 years. That experience shows in how we handle complex roof lines, unexpected deck damage, and insurance claim disputes. We've seen everything and know how to handle it.
