Fontana Roof Pros provides professional roof leak repair in Fontana, CA for residential and commercial properties across the western Inland Empire. Most leaks in this city are not caused by rain. They are caused by six months of heat opening a joint, and then found by the first honest storm in December. That changes how the repair is diagnosed, because the water shows up months after the damage was done.
The usual culprit is a rubber pipe boot. Ultraviolet light and daily thermal movement crack the collar around the vent stack, and on a roof past twelve summers we expect to find every boot on the house split at the same point. A boot is a small part. Replacing all of them at once, rather than the one over the stain, is the repair that holds.
After boots, the recurring finds are exposed fasteners that have backed out as the metal beneath them expanded and contracted, mastic at a wall-to-roof transition that has chalked and pulled away from the stucco, and a thermal split where a long run of counter-flashing was set with no allowance for movement. None of those is fixed with a tube of sealant over the top, because the material that failed was a sealant.
We diagnose with water. The crew runs a hose in a deliberate sequence, low on the plane first and working uphill, with someone in the attic watching the sheathing rather than the ceiling. It is slower than a walk-around and it is the only way to separate a roof leak from evaporative cooler overflow, a stucco leak, or condensation on ductwork.
Then there is the repair we get thanked for least and mean most. If the roof is at the end of its service life, patching the west plane is spending money to postpone a conversation. We will tell you that on site, in writing, with photographs of the granule cover and the sealed course, and you can decide the timing without a salesperson in your kitchen.
Small leaks stay small here for one reason: no freeze cycle drives water sideways through a ceiling. That works in your favor. We also pull insulation back at the wet rafter bay, since water runs along framing and stains a ceiling several feet from the hole. Call the stain in while it is the size of a dinner plate and the repair is usually a boot, a length of flashing, and an afternoon.
Our licensed and insured team brings the right materials and equipment to every job — cool-rated architectural shingles, high-temperature SBS-modified underlayment, batten-set concrete tile with a one-inch air space, Kynar 500 PVDF standing-seam panels, heat-welded TPO membrane, reflective elastomeric coating — and backs the work with a written workmanship warranty. We serve Fontana and nearby communities including Rialto, Bloomington, Colton, Grand Terrace.

Materials, equipment and how we do roof leak repair
The difference between roof leak repair that lasts and roof leak repair that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with cool-rated architectural shingles, high-temperature SBS-modified underlayment, batten-set concrete tile with a one-inch air space, Kynar 500 PVDF standing-seam panels, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Fontana job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the western Inland Empire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
