AfterFast, Reliable Roof Repair Across University of California-Davis
Roof repair in University of California-Davis usually runs $350 – $900 for shingle and flashing work, while decking replacement or solar re-flashing can push a job to $1,200 – $2,800. Most repairs we do here are scheduled within the week. A leak over your kitchen in Old North is not something to let sit, not with the valley oak dropping debris into your gutters and the winter rains coming. Call Brennan Roofing at (361) 320-9467 and we’ll get a written price in your hand before any work starts.
We work all over University of California-Davis, from the 1960s tract homes near Slide Hill Park to the older ranches in College Park and the student rentals west of Highway 113. Each neighborhood has its own roof problems, and we’ve seen most of them. Davis is a small enough town that word travels, and a repair crew that leaves a mess on Russell Boulevard hears about it for years. We don’t operate that way.
Every Brennan Roofing technician who steps onto a University of California-Davis roof is background-checked and in uniform. The price goes on paper before work begins. If it’s not done right, the 365-Day Done Right Promise means we come back and fix it, in writing, at no charge for a full year. That’s the Garrison Standard, and it applies the same on a $400 valley repair as it does on a full re-roof.
Why Brennan Roofing Is University of California-Davis’s Preferred Roof Repair Company
University of California-Davis homeowners call us because we answer the phone with a live person, not a voicemail tree. That matters when you’ve got water coming through the ceiling on a Sunday night. We dispatch crews to University of California-Davis from our Los Angeles office, but the technician at your door knows Davis. He knows what a valley oak does to a gutter system. He knows the difference between a 3-tab shingle from a 1978 tract home and the architectural shingles on a College Park remodel.
Our reputation in University of California-Davis is built on showing up inside the promised window and leaving the job site cleaner than we found it. Homeowners here tend to be methodical, and they appreciate that we hand them a written line-item quote that does not move at the door. The quote includes material, labor, and any decking allowance. When the inspection turns up something extra, we explain it, price it, and get approval in writing before we touch a single shingle.
Travis Oakley, who leads Brennan Roofing, put the 365-Day Done Right Promise in place for a reason. Roof repairs fail quietly sometimes. A flashing leak comes back after the first big storm. Under that guarantee, you call us and we come back free. No argument. That’s what keeps our University of California-Davis customers referring us to their neighbors.
Metal Roof Repair in University of California-Davis
Metal Roof Repair in University of California-Davis typically costs $450 – $1,400 depending on what failed. Most metal roofs in Davis are standing seam or corrugated panels on newer builds and solar-heavy homes near campus. These roofs hold up well to Davis’s 100°F summers, but the fasteners, sealants, and flashings around penetrations age faster than the panels themselves. A leak near a vent boot or a solar mount on a metal roof is usually a failed gasket or a loose seam, not the metal itself.
Fastener and Penetration Failures
On metal roofs in Davis, the rubber gaskets under fasteners dry out and crack after ten to fifteen years of intense UV. That lets water creep under the panel edge, and the first sign is often a stain near a ridge or a pipe boot. We replace the failed fasteners and boots, re-seal the penetrations, and check the surrounding panels for movement.
Seam and Flashing Repairs
Metal roof seams that were crimped or seal-tapped years ago can separate, especially on low-slope sections that hold water during the wet season. We re-secure the seam and install new flashing where the metal meets a wall, chimney, or skylight. On Davis homes with solar arrays, we re-flash the mounts before re-seating any panel that had to be lifted.
Commercial Roof Repair in University of California-Davis
Commercial Roof Repair in University of California-Davis runs $900 – $4,500 for typical flat and low-slope roof work, with larger TPO or modified bitumen repairs beyond that. Davis has a mix of small retail buildings downtown, apartment complexes east of campus, and light industrial spaces near the railroad tracks. These buildings often have flat or low-slope roofs that pond water after heavy winter rains, which means a small membrane puncture turns into a big interior problem fast.
Flat and Low-Slope Membrane Work
University of California-Davis commercial roofs take a beating from the valley sun, which degrades TPO and modified bitumen surfaces faster than coastal California cities. We locate punctures, seam failures, and blisters, then patch them with materials matched to the existing membrane. If the insulation underneath is waterlogged, we cut out the wet section and replace it before re-seaming the surface.
Drainage and Ponding Corrections
Flat roofs that pond water near drains or scuppers in Davis will fail repeatedly until the drainage is fixed. We repair or replace drain baskets, clear clogged downspouts, and build small crickets where needed to move water off the roof. For commercial properties with rooftop HVAC units, we inspect and re-flash the curb penetrations as part of every repair, since those are the most common leak source on flat roofs.
Trusted Brands We Service in University of California-Davis
Our Roof Repair team works with GAF, CertainTeed, and Owens Corning shingles every week across University of California-Davis. That means we can match your existing roof instead of leaving a patch that looks like a band-aid. We keep common valley metals, vent boots, and drip edge pieces stocked so a standard repair doesn’t get held up waiting on a distributor. If your home carries a specific shingle line, like GAF Timberline or CertainTeed Landmark, tell us when you call and we’ll bring the right color and profile with us.
Common Roof Repair Problems We See in University of California-Davis Homes
- Debris dams in valleys and behind chimney flashing. In Old North and College Park, valley oaks and redwoods drop leaves, acorns, and small branches year-round. A clogged valley holds water against the roofing material and rots the decking underneath. By the time you see the stain on the ceiling, the problem has usually been building for a year or more.
- Soft decking hidden under original 1960s and 1970s shingles. Most of the ranches in Davis still have their original 3-tab shingles or are on their first replacement. The decking underneath is often plywood that’s been under a leaking flashing for years. A simple shingle replacement sometimes reveals a decking patch that has to go in before the shingles do.
- Solar penetration leaks on 1970s and 1980s tract roofs. A growing share of homes near campus and along Anderson Road carry rooftop solar. Mounts were often flashed over old underlayment that’s now brittle, so water tracks along the brackets and into the attic. We re-flash the mounts and re-seal the array before replacing any shingles around it.
- Moss and algae streaking that hides underlying rot. The heavy canopy in Old North shades roofs enough that moss grows thick on north-facing slopes. That moss holds moisture against the shingles and slowly degrades the granule surface. When we quote a repair in those neighborhoods, we inspect for organic growth first because it changes the scope.
Pricing for Roof Repair in University of California-Davis, CA
What you’ll pay for roof repair in University of California-Davis depends on what the inspection turns up. A shingle replacement runs $350 – $900 for a typical repair. Flashing repair around a chimney or skylight runs $450 – $1,100. Valley repair, which often includes new metal and re-sealing, runs $600 – $1,500. If decking is soft and needs replacement, add $8 – $14 per square foot of decking. Solar re-flashing on an existing array can add $800 – $2,000 depending on how many mounts need to be lifted and re-sealed.
We don’t give you a number over the phone and then add to it at the door. The written quote you get from Brennan Roofing includes everything we found during inspection. If we open the roof and find something we couldn’t see from outside, we stop, we call you, we price it, and you approve it before we continue. Call (361) 320-9467 for a free estimate, and we’ll put the price in writing.

FAQs About Roof Repair in University of California-Davis
Green streaking is the visible sign that moss and algae are holding moisture against your shingles, and in Old North and College Park it shortens the life of a roof more than any other single factor. The algae itself doesn’t always cause a leak, but the moisture it traps accelerates granule loss and makes the shingle surface more porous. Have us inspect it before you decide to leave it alone, because a moss-covered valley that’s hiding a debris dam below is a repair waiting to happen. Call (361) 320-9467 and we’ll take a look for free.
You should ask the roofer to show you the soft spots before you agree to anything. Decking that’s been wet for years is visible and measurable; it’s not a judgment call. If a contractor won’t let you see the damaged area or won’t put the decking allowance in writing before work starts, find another roofer. Brennan Roofing writes decking into the contract as a per-square-foot allowance, and if we find damaged decking during the repair, we show you before we replace it.
In most cases, yes. We remove only the panels needed to access the mount flashing, re-flash or re-seal the penetrations, and then re-seat the array. Removing an entire solar array is rarely necessary for a roof repair unless the decking under the whole array section is involved. University of California-Davis homes with solar on the south and west slopes see mount leaks most often near the array edges where wind-driven rain and the sun’s heat stress the sealant first.
Your quote should be line-itemed, and it should include the specific material and color being installed, the labor, any decking replacement with a per-square-foot price, any flashing or drip edge work, and the warranty term in writing. If a bid is a single lump sum with no breakdown, you can’t compare it fairly to another. Brennan Roofing gives you that breakdown before any work starts, and the number does not move at the door.
Davis has strict tree ordinances, and in neighborhoods like Old North and College Park, protected valley oaks and redwoods often overhang roofs. A repair crew cannot simply cut back interfering branches without a permit or approval in many cases. We work around the canopy as-is, and if a branch is physically blocking a repair, we tell you what’s needed and you coordinate with the city arborist before any cutting happens. That’s a Davis-specific problem, and it’s one reason local crews who know the rules are worth working with.
