Fontana Roof Pros provides professional chimney flashing in Fontana, CA for residential and commercial properties across the western Inland Empire. A chimney and the roof around it are two materials moving at different rates every single day. Masonry and framed lumber expand and contract by different amounts, and in a climate with a thirty-degree swing between afternoon and dawn, that joint gets worked hundreds of times a year.
Flashing either accommodates that movement or it fails, which is why the repair we get called to fix most is a bead of sealant smeared where the flashing meets the brick. It looks like a fix for about two summers. Then it chalks, shrinks, pulls off the masonry, and now water is running behind it into the joint instead of over the top of it. Roof cement over the same joint does the same thing faster.
The detail that lasts has three parts. Step flashing woven into the field one piece per shingle course up both sides. A counter-flashing cut into a reglet in the mortar joint, folded, and locked over the step flashing so the water path is mechanical rather than adhesive. And a high-temperature polyurethane or polyether sealant used only to close the reglet, never as the waterproofing.
Anything wider than about thirty inches on the upslope side needs a cricket — a small framed and flashed saddle that splits water around the chimney instead of letting it pond against the back wall. Fontana gets few storms and they arrive hard, so a chimney back that holds water for six hours once a winter rots a deck as thoroughly as steady drizzle would.
Half the chimneys we work on out here are not masonry at all. They are framed chases clad in stucco with a metal chase cover on top, standard on 1990s and 2000s tract housing. The cover is where they leak: flat, unsloped galvanized steel that rusts through at the seams, with sealant around the flue that dried out a decade ago.
A cross-broken stainless or coated cover with the right collar is the fix, and it is not expensive. We check the crown, the flue collar and the spark arrestor while we are up there, and we say plainly when a chimney needs a mason instead of a roofer. Cracked crowns and spalled brick are not flashing problems, and treating them as flashing problems wastes your money twice.
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 chimney flashing
The difference between chimney flashing that lasts and chimney flashing 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.
