Fast, Reliable Roof Repair Across Ashland
Roof repair in Ashland typically runs $350 – $1,400 for most single-visit fixes like valley re-flashing, vent boot replacement, or a small shingle patch. The bigger variable here isn’t labor, it’s the condition of what’s underneath. Ashland’s hillside homes, many built in the 1950s and 60s, often hide rotted decking beneath what looks like a simple leak. That’s why we write the price down before any work starts, and it doesn’t move at the door. Call (831) 318-8819 for a straight answer and a free estimate.

Why Brennan Roofing Co San Francisco Is Ashland’s Preferred Roof Repair Company
Travis Oakley runs our crews to what we call The Garrison Standard. It’s a written code that covers how we show up, how we price, and what happens if something goes wrong. We don’t ask Ashland homeowners to trust us on vibes. We hand them a written price before any work starts, and we back every repair with a 365-Day Done Right Promise: if it fails within a year, we come back and fix it at no charge.
Our Roof Repair team knows what Ashland roofs actually deal with. We’ve repaired valleys on homes off Webster Street that had been leaking for years, slowly rotting the soffit while the owners thought the stains were just old water marks. We’ve replaced vent boots on Eldridge-area homes where the rubber had cracked so badly you could see daylight. Local knowledge isn’t a marketing phrase here. It’s the difference between patching a symptom and stopping the leak.
Ashland homeowners call us because they’ve been burned by roofers who no-show or raise the price after the tear-off. We answer the phone with a live person every time. We show up when we say we will. And the price you sign is the price you pay.
Styles & brands we work with






Storm Damage Roof Repair in Ashland
Storm Damage Roof Repair in Ashland usually follows the first heavy rain of the season, when wind-driven water finds every weakness that developed during the long dry summer. Ashland’s Mediterranean climate means shingles bake in the sun for months, then get hammered by concentrated winter rains. That combination, repeated year after year, is why so many Ashland homes need repairs at flashings, valleys, and penetrations rather than across entire roof planes. A typical storm-related repair here costs $400 – $1,600 depending on how much decking got wet.
Wind and Rain Damage Assessment
We start by walking the roof surface and the perimeter. Lifted shingles near the eaves, granule loss in the valleys, and damp insulation in the attic tell us where water got in and how far it traveled. Ashland’s sloping lots mean runoff moves fast, so a small flashing gap can soak a large section of decking before anyone sees a stain on the ceiling.
Fast Response and Written Scope
When you call about storm damage, we schedule a visit quickly and put the scope in writing. That means you know the price before we start, and we know exactly what we’re fixing. No open-ended time-and-materials work. No surprises after tear-off.
Metal Roof Repair in Ashland
Metal Roof Repair in Ashland covers everything from resealing a leaking standing-seam panel to replacing rusted fasteners on a corrugated roof. Metal roofs handle Ashland’s dry summers well, but the thermal expansion between hot days and cold nights stresses seams, fasteners, and transition flashings. When a metal roof leaks here, it’s usually at a penetration: a pipe boot, a skylight curb, or the transition where the metal meets a composition shingle eave. Repair costs run $450 – $1,800, with the higher end covering panel replacement or seam re-caulking on steep slopes.
Seam and Fastener Repair
We inspect the seam tolerances and replace any fasteners that have backed out or rusted. On older Ashland metal roofs, we often find that the original installers used neoprene washers that have dried and cracked, letting water wick under the panel. We replace those and reseal the seams with materials matched to your panel profile.

Transition and Penetration Flashing
Most metal roof leaks in Ashland happen where the metal roof meets something else: a chimney, a wall, or a gutter. We re-flash those transitions carefully, because a metal roof is only as dry as its worst joint.
Trusted Brands We Service in Ashland
We stock and install materials from GAF, CertainTeed, and Tamko, which covers the majority of composition shingle roofs in Ashland. When a repair calls for matching an existing architectural shingle, we can usually pull the exact color and profile from local supply stock and have it on your roof the same week. For Ashland homes in the Wildland-Urban Interface zone, we recommend and install fire-rated assemblies that meet current WUI code, and we explain plainly what that means for your specific roof instead of burying you in manufacturer jargon. If your roof currently has a brand we haven’t named here, call us anyway. If the material is still in production, we can source it.

AfterCommon Roof Repair Problems We See in Ashland Homes
- Valley and flashing failures from thermal cycling: Ashland’s hot, dry summers expand metal flashings and shingles; the wet winters contract them. Over a decade or two, that movement cracks sealant and opens gaps exactly where water concentrates. We re-flash valleys with proper underlayment so the repair outlasts the original install.
- Moss and moisture retention on shaded low-slope roofs: Many Ashland homes have oak or eucalyptus shade on the north side. Moss grows on those shingle sections, trapping moisture against the granule surface and accelerating decay. The rot underneath often extends into the decking before any leak shows inside.
- Rotted decking beneath old leak stains: By the time most Ashland homeowners see a ceiling stain, the water has been traveling through the decking for months or years. We frequently find decking that crumbles when you touch it. You can’t patch over that; you replace the section.
- WUI code compliance failures at final inspection: Ashland inspectors check roof repairs in the Wildland-Urban Interface zone for fire-safe underlayment and debris-free gutters. We have seen otherwise solid repairs get red-tagged because the gutters were full of dry leaves. We clear the gutters, document it, and walk the inspector through the finished work.

FAQs About Roof Repair in Ashland
Yes. Ashland sits within a Wildland-Urban Interface zone, and roof repairs that involve decking replacement or material changes typically require a permit and inspection. The inspector will check that your underlayment meets fire-safe standards and that gutters are clear of dry debris. If the roof itself is fine but the defensible space isn’t, the final sign-off can stall. We handle the permit paperwork and prep the job so the inspection passes on the first visit. Call (831) 318-8819 if you’re not sure whether your repair triggers the WUI requirements, we’ll tell you straight.
We stop leaks at valleys and penetrations by pulling the old flashing, inspecting the decking beneath, and installing new underlayment and metal before re-shingling. On Ashland’s hillside homes, water concentrates at valleys during winter rain, so we run ice and water shield along the valley lines and up the sidewalls. For penetrations like plumbing vents and attic fans, we replace the boot and re-seal around the base with a properly lapped flashing. The old fix of just caulking over the gap lasts about a season here. We build the repair to outlast the roof’s remaining life.
In roofing, a “square” is 100 square feet of roof surface. When a quote lists three squares, that’s 300 square feet of material. We use the trade term because that’s how shingles, underlayment, and decking are sold, and we’re happy to walk you through the math on your specific estimate. If a quote from another roofer switches between squares and square feet without explaining the conversion, that’s a red flag. Our written estimates show the roof area, the material count, and the labor line by line. Call (831) 318-8819 and we’ll go over any estimate you’ve received and translate it into plain English, free.
Yes, in most cases you can replace individual sheets of damaged decking and rotted soffit sections without tearing off the entire roof. We do this all the time in Ashland, especially on homes where a leak sat unnoticed in one area while the rest of the roof remained sound. We strip shingles only over the damaged decking, replace it with like-for-like plywood or OSB, re-lay underlayment, and shingle to match. The key is getting the seam between old and new decking flashed and supported correctly. If the damage is widespread, a full replacement may cost less per square than piecemeal repairs, and we’ll tell you that plainly.
Yes, and more than most homeowners expect. Ashland’s hillside lots, especially those facing the open slope above the bay or sitting exposed on a ridge, catch wind that never touches the flatland houses down near the boulevard. Architectural shingles with a higher wind rating, such as 110-mph or 130-mph products from GAF or CertainTeed, resist lifting and edge tear-out far better on those exposures. We also inspect and upgrade the drip edge and starter course, because that’s where wind gets its first grip. If your existing roof is losing shingles at the corners or ridges during winter storms, the wind rating on what you’re reinstalling matters.
If you need roof repair in Ashland and want a written price before anything gets torn off, call (831) 318-8819. A live person answers. You’ll get a straight answer about what’s wrong, what it costs, and what we’ll do if it fails within the year. That’s the Garrison Standard, and it applies to every job we run in Ashland.
