Flashing Repair in Fresno, CA

Flashing Repair in Fresno, CA

Roof flashing repair in Fresno typically costs between $220 and $480 for most residential fixes, depending on where the leak is and how much flashing needs to come out. Flashing is the metal material, usually galvanized steel or aluminum, that seals the joints where your roof meets a wall, chimney, vent pipe, or valley. When it fails, water gets in. We get it fixed, usually same day, and the price goes on paper before any work starts. Call (559) 785-2160 for a free estimate.

At Brennan Roofing Co Fresno, flashing repair is one part of our broader Roof Repair in Fresno work, and we treat it with the same discipline we bring to full roof replacements. Travis Oakley runs our Fresno operation under The Garrison Standard: written price before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise in writing on every job. Most flashing failures start small. Left alone through a Fresno summer of 100-degree days and a wet winter, they become decking rot and interior damage. We’d rather catch it now.

When You Need Flashing Repair

Flashing is quiet until it fails. You won’t hear it. You’ll see the stain on the ceiling or smell the damp in the attic. Here are the specific situations we see most often in Fresno and the surrounding neighborhoods, from Woodward Park to Tower District to Sunnyside:

• Water stains on the ceiling or walls near a chimney or exterior wall line. This is the classic flashing failure. Water follows the joint between the chimney and roof, or the wall and roofline, and shows up inside. If the stain is directly below a chimney or where a second-story wall meets the roof, flashing is the first place we check.
• Visible rust, corrosion, or separation on exposed metal flashing. Fresno’s dry heat bakes flashing and the winter rain cycles cause expansion and contraction. Over time, metal pulls away from the seam, cracks at the bend, or rusts through. If you can see daylight through a gap or heavy rust flaking off the metal, it’s done.
• Granules from shingles collecting in gutters near valleys and penetrations. When flashing fails and water pools, shingles near the flashing degrade faster. You’ll see granules in the gutter below a valley or pipe boot. That’s not normal shingle wear. That’s water working the seam.
• Leaks around vent pipes, skylights, or roof penetrations on the north-facing slope. North slopes in Fresno hold moisture longer in winter, and pipe boots crack under UV exposure. A failed pipe boot cost us a lot of repairs over the years that could have been caught for under $300.
• Your last roof repair sealed the shingles but the leak came back. If a previous roofer caulked or tarred over shingles and the leak returned in the same spot, the flashing was never addressed. Sealant is not flashing. We see this routinely after bad weather. A good repair replaces the flashing, not the caulk.
• Attic mold or damp insulation near roof-wall intersections. Flashing failures don’t always stain the ceiling. Sometimes they drip into the attic and soak the insulation. If you’re up there and notice a musty smell or damp fiberglass near the eaves, get the flashing checked before the decking rots.

If any of this describes what you’re seeing, the fix is usually straightforward and we can typically get a technician out within one to two days. Call (559) 785-2160 and we’ll set a time. The inspection is free.

Our Flashing Repair Process

We don’t guess. Here’s how flashing repair works when you call Brennan Roofing Co Fresno:

1. Inspection and diagnosis. A background-checked, uniformed technician gets on the roof and locates the failed flashing. We look at every penetration and intersection, not just the one you called about. The inspection is free. We’ll show you photos of what we find and explain it in plain English.
2. Written price before any work starts. No exceptions. You get the number on paper, and that number does not move at the door. If we find something additional after the work begins, we stop and talk to you first. The Garrison Standard exists for this exact moment.
3. Removal of old flashing. We pull the failed metal, remove old sealant and roofing cement, and inspect the underlayment and decking underneath. If the wood is soft, you’ll know before we go further. We show you the damage.
4. New flashing installation. We install new flashing correctly, with proper overlap and new fasteners. We use materials from manufacturers including GAF, CertainTeed, and Tamko, and we match the new flashing to your existing roof system so the repair doesn’t look like a patch.
5. Seal, reinstall, and clean up. We re-seat shingles around the new flashing, seal the seams with the right sealant for our climate, and clean the job site. You won’t find old nails in the yard or flashing scraps on the roof.
6. Written guarantee. You get the 365-Day Done Right Promise in writing. If the flashing fails within one full year, we come back and fix it at no charge. That’s not a verbal promise. It’s the way we work.

Flashing Repair Pricing in Fresno

We give straight numbers because you shouldn’t have to call just to get a ballpark. Here’s what flashing repair realistically costs in Fresno, and for broader context see our full guide on How Much Does Roof Repair Cost? (2026 Price Guide) - Fresno, CA:

• Pipe boot or vent pipe flashing replacement: $220 – $340
• Step flashing repair at a wall intersection (single story): $300 – $480
• Chimney flashing repair or replacement (saddle, apron, step, and counter-flashing): $450 – $850
• Valley flashing repair or replacement: $400 – $700
• Skylight flashing replacement: $380 – $650
• Full flashing replacement on multiple penetrations: $900 – $2,000+

What moves the number? Three things. First, accessibility: a single-story roof in Clovis or north Fresno is faster to work on than a steep two-story pitch in the foothills. Second, the condition of the surrounding materials: if shingles near the flashing are brittle and need replacement, that adds material cost. Third, the type of flashing required: custom-bent metal for a chimney costs more than a Flat Roof Patch or standard pipe boot off the shelf.

Here’s the part that matters most: the price we write down before work starts is the price you pay. If the repair is smaller than expected, the price comes down. If it’s bigger, we talk to you before spending another dollar. Call (559) 785-2160 for an exact quote. Estimates are free.

Roof Flashing in the Fresno Climate

Fresno’s climate is hard on flashing in a way that coastal cities don’t experience. We get 100-plus degree days from June through September, and the metal on your roof expands in that heat. Then the temperature drops at night and the metal contracts. Multiply that cycle by three decades and the metal fatigues at the bends, which is exactly where flashing fails first. Then winter rains arrive and the water finds the microscopic gap.

In Sunnyside and the older Fresno High area, we see a lot of original galvanized flashing from the 1970s and 80s that has simply rusted through. In newer subdivisions like those near Clovis Unified and the Loma Vista area, the issue is more often installation shortcuts: flashing nailed too high, improper overlap, or sealant used as a substitute for metal. Both fail. We replace both with the same standard.

That standard includes material. We install flashing from manufacturers including GAF, CertainTeed, and Tamko, and we’ll explain the trade-offs so you can decide with confidence. Galvanized steel is the workhorse. Aluminum is lighter and won’t rust but costs more. Copper lasts decades and costs considerably more. You’ll get the honest version of this conversation, not a sales pitch for the most expensive option.

Repair or Replace: How We Advise Homeowners

Flashing repair is usually a localized Roof Repair and we don’t push full roof replacement when a $300 pipe boot solves the problem. But there are times when repair alone doesn’t make sense. If the leak has been active long enough to rot the decking, replacing the flashing is not enough. You need the decking replaced and possibly the surrounding shingles. If the flashing failure is widespread, on a roof that’s already 20-plus years old, patching becomes an endless game of whack-a-mole.

Our approach is simple. We’ll tell you what’s needed to stop the leak immediately, and we’ll tell you what’s needed to prevent the next one. Those are sometimes two different numbers. You’ll have both in writing before any work starts. And if your roof needs more than flashing, our Roof Repair in Fresno team handles that too, from underlayment replacement to full re-roofing. We won’t call it repair if replacement is the honest answer.

The Garrison Standard on Every Flashing Repair

Brennan Roofing Co Fresno is an independently owned and operated member of the Garrison Partners family, founded in 2000. We’re local, and we answer to Fresno homeowners. The Garrison Standard is what we call the operating code every technician works under, and it applies to a $280 pipe boot exactly the same as it applies to a $22,000 full roof replacement.

That means the technician who shows up at your door is background-checked and in uniform. You know exactly who is on your roof. It means the price is written down before any work starts, and it does not move. It means the work is backed by the 365-Day Done Right Promise, in writing, for one full year, with a free return visit at no charge if the repair fails within that period. It means when you call at 2 a.m. with water coming through the ceiling, a live person answers. No voicemail, no automated system.

The Garrison Code, the written standard we operate under, is the reason a homeowner in the Tower District gets the same discipline as a homeowner in Woodward Park. It’s not a slogan. It’s how we run the business.

FAQs – Flashing Repair

How much does flashing repair cost in Fresno?

Flashing repair in Fresno costs between $220 and $480 for most single-location fixes like pipe boots and step flashing, while chimney flashing and valley work typically runs $450 to $850. The price depends on accessibility, the type of flashing required, and the condition of surrounding materials. Call (559) 785-2160 for an exact quote. Estimates are free, and the price goes in writing before any work starts.

Can you fix roof flashing the same day?

Yes, in most cases we can repair roof flashing the same day or within 24 hours, especially when there’s an active leak. Call (559) 785-2160 and a live person will answer, 24/7. If water is coming through, we’ll prioritize your call.

Is it cheaper to repair flashing or replace the roof?

Repairing flashing is almost always cheaper than replacing the roof, usually by thousands of dollars. A failed pipe boot costs $220 to $340 to fix, while a full re-roof in Fresno runs $12,000 to $25,000 or more. That said, if the leak has rotted the decking or the roof is at the end of its life, patching becomes false economy. We’ll give you both numbers in writing and let you decide with clear information.

How long does flashing repair last?

Properly installed flashing lasts 20 to 35 years in the Fresno climate, depending on the material and exposure. Cheaper materials and sealant-heavy installs fail much sooner, which is why we install new metal rather than re-caulking old flashing. Our work is guaranteed in writing for one full year under the 365-Day Done Right Promise, and we come back for free if the repair fails within that period.
