Chimney Flashing Repair & Replacement
Our Chimney Flashing Repair & Replacement service addresses leaks and damages. Ideal for homeowners in Covina, we ensure your chimney is properly sealed against the elements.
Explore →Flashing is the metal work that seals the joint where your chimney passes through your roof — and it’s where most Covina chimney leaks actually start. When flashing rusts, lifts, or was sealed with caulk instead of being built in properly, every rain pushes water into your attic, walls, and ceiling. FlashGuard Chimney Flashing Repair, at 440 N Barranca Ave in Covina, finds the real entry point and fixes it with metal work that’s built to move with your roof — not just smeared over.

You usually can’t see flashing fail from the ground. What you see is what the water does next:
Any one of these is worth a look before the next storm — small flashing failures are cheap, but the rotted decking and mold behind them are not. If the stain is already there, start with our chimney leak repair in Covina page: it walks through every place water gets in at the top of a chimney, and what each fix involves.
Flashing isn’t the only way in, either. A cracked crown or a missing cap lets water pour straight down the flue. That’s why every FlashGuard visit covers the whole top of the chimney — flashing, crown, cap, and mortar — in a single inspection.
Water gets in through five places, and they’re all connected. We handle each of them:
Typical flashing costs in Covina: reseal $250–$500 · partial replacement $500–$1,000 · full replacement $900–$1,800+ — see what chimney flashing repair costs in Covina for the full cost guide.
Most failed flashing we tear out was never really flashing at all — it was a tube of sealant and a prayer. Here is what a proper job looks like:
Individual metal pieces woven into the shingles so water is shed course by course — never a single long strip that traps it.
The top edge is set into a ground mortar joint and pointed over, so the seal is mechanical, not a bead of caulk waiting to split.
The downhill face and the uphill dam get their own pieces; wide chimneys get a cricket to split the flow before it arrives.
Galvanized steel standard, stainless or copper where the roof and budget call for it — and sealant used as a supplement, never the system.
If your flashing was installed with face-nails and tar, a proper replacement is usually a one-day job — see our guide to chimney flashing repair costs in Covina for what it runs, or read more about chimney flashing repair and replacement.
We look at the flashing, crown, cap, and mortar, and photograph what we find.

FlashGuard is based at 440 N Barranca Ave — we’re a Covina company working on Covina roofs: the tile and composition shingles, stucco chimneys, and mid-century fireplaces that fill Downtown Covina, Charter Oak, Covina Heights, North Covina, Covina Hills, South Hills, Covina Park, Cypress Park, and Lark Ellen, plus West Covina, Azusa, Glendora, San Dimas, and Baldwin Park.
Covina’s rain doesn’t fall often, but when a Pacific storm parks over the San Gabriel Valley for three days, marginal flashing fails all at once. Most of our leak calls come in the same week, from the same streets — which is why we push inspections in the fall, before the first real rain.

Here are some common questions about Chimney Flashing Repair Covina CA.
(626) 4795904 →Most repairs run $250–$1,000. Resealing flashing that’s still sound costs $250–$500; replacing one or two sections, $500–$1,000; a full flashing replacement typically runs $900–$1,800 or more, depending on roof access, chimney size, and material. You’ll always get a written price after inspection, before work starts. (Full breakdown: chimney flashing repair costs in Covina.)
Stains that appear on the ceiling near the fireplace, worsen after rain, and sit below the chimney’s roofline almost always trace back to the flashing. Crown cracks and missing caps cause leaks too — which is why we inspect the whole top of the chimney before recommending any repair.
If the metal is sound and only the seal has failed, a reseal is a legitimate fix. If the flashing is rusted through, incorrectly lapped, or was only ever surface-sealed, replacement is the honest answer — resealing dead metal just buys you another leak next season.
Most replacements are completed in a single day. Reseals and single-section repairs usually take a few hours.
