This page is written for Lafayette homeowners who want to know what a roofing company actually charges here and how we handle the surprises that come with opening up a 1950s or 1960s roof. Travis Oakley runs our crew, and the standard he holds us to is the same on every house: written pricing, background-checked technicians in uniform, and a 365-day guarantee in writing.
Why Brennan Roofing Is Lafayette’s Preferred Roofing Company
Lafayette homeowners call us because we show up when we say we will and the number on the estimate is the number on the invoice. Our Roofing Company team has worked on ranches along Happy Valley Road, two-story traditionals near Acalanes High School, and newer custom homes up in the Reliez Valley hills. Each one taught us something about how this town’s tree canopy and winter storms interact with roofing.
We answer the phone live around the clock. When a February storm tears shingles off the downhill plane of a house on Upper Happy Valley Road, the homeowner talks to a person immediately, not a callback queue. Every technician who steps onto a Lafayette roof is background-checked and in uniform, so you know exactly who is on your property. The work carries the Garrison Standard: a written price before anything starts, and the 365-Day Done Right Promise in writing for a full year. If a repair fails inside that year, we come back free.
We are an independently owned and operated member of the Garrison Partners family, founded in 2000, with dispatch coordinated from our San Francisco Bay Area office. Lafayette is our backyard, not a territory on a map.
Roof Coating in Lafayette
Roof coating in Lafayette typically costs between $2,800 and $6,500 for a single-family home, depending on roof size and the condition of the existing surface. For flat or low-slope roofs, a coating can extend the life of an aging roof by sealing small cracks and restoring reflectivity, which matters during Lafayette’s warm, dry summers when direct sun beats on exposed roofs for months.
Cool Roof Coatings
In Lafayette’s Mediterranean climate, a reflective coating does real work. It cuts surface temperatures on flat roof sections, which reduces heat load on the house and slows the expansion-contraction cycle that cracks aging membranes. We apply coatings to clean, dry surfaces after repairing any blisters or splits.
Coating After Repair
We often recommend a coating after completing repairs on a low-slope roof. The repair fixes the leak; the coating buys time before full replacement. For a Lafayette homeowner with a flat roof section over a garage or addition, this is usually the most practical move when the decking is still sound.
Free Roof Estimate in Lafayette
A free roof estimate in Lafayette means one of our technicians inspects the roof, walks you through what we found, and leaves you with a written line-item price, not a verbal ballpark. There is no charge for the visit and no obligation. Call (361) 320-9467 and we will schedule it around your day.
What the Estimate Includes
The estimate lists materials, labor, decking replacement allowances, flashing work, underlayment, and disposal. If we open the roof and find the decking is rotted or the original underlayment is gone, the allowance we wrote into the contract covers the first layer of scope. Anything beyond that gets priced in writing and approved by you before we touch it.
Why We Write It Down
Lafayette homeowners have been burned by roofers who shift their price at the door. We do not do that. The Garrison Standard means the number goes on paper before any work starts and it does not move unless you approve a written change order. That is the whole point of a free estimate: you walk away with a real number, not a sales pitch.
Trusted Brands We Service in Lafayette
We install materials from GAF, CertainTeed, Owens Corning, and a select set of other manufacturer lines, including Atlas and Boral. For Lafayette homes, GAF Timberline HDZ architectural shingles are a common choice because they hold a high wind rating, which matters on the downhill exposures where winter gusts accelerate through the tree gaps. For tile roof replacements, Boral concrete tile gives homeowners a fire-resistant option that suits the traditional look of many Lafayette neighborhoods. We stock common flashing, underlayment, and drip edge components locally, which means faster turnaround when a storm opens up a section of roof.
Common Roofing Company Problems We See in Lafayette Homes
- Debris-clogged valleys and gutters. Mature oaks and redwoods drop leaves, needles, and small branches year round. When debris dams water in a valley, it backs up under shingles and into the decking during the first heavy November rain.
- Original wood-shake roofs on 1950s to 1970s homes. Many Lafayette ranches and two-story traditionals still carry wood shake roofs that are decades past their service life. Patching individual shakes without replacing the failed underlayment underneath is a temporary fix that fails again in the next wet season.
- Missing ice and water shield at valleys and penetrations. Older Lafayette homes were often built before ice and water shield became code. Valleys, chimneys, and vent pipes are the most vulnerable spots when debris dams water, and they leak first.
- Downhill-side wind damage. After a windstorm, the most severe damage consistently shows up on the downhill side of a home, where wind accelerates through gaps in the oak and redwood canopy. Shingles on that exposure need a six-nail pattern and proper underlayment fastening or they lift in the next storm.
Pricing for Roofing Company in Lafayette, CA
A full roof replacement on a typical Lafayette single-family home runs $14,000 to $28,000. A standard asphalt shingle roof on a 1,800-square-foot ranch usually lands between $14,000 and $19,000. Metal roofing runs higher, typically $22,000 to $35,000, and tile roofing is $28,000 to $45,000 depending on whether the existing tile can be reused. Repairs range from $450 for a small flashing fix to $1,800 or more for valley rebuilds or decking replacement. Flat roof coating runs $2,800 to $6,500. The biggest cost variables are roof size, pitch, the condition of the decking, and whether your home requires code-triggered upgrades like edge metal or ventilation improvements. We write allowances for decking and code upgrades into every estimate, so the price does not move mid-job without your written approval.

FAQs About Roofing Company in Lafayette
The downhill roof plane fails first because winter winds accelerate through gaps in the oak and redwood canopy and hit that exposure at full force. In Lafayette, we regularly see lifted shingles, torn flashing, and driven rain on the downhill side while the uphill plane is barely touched. Flatland contractors miss this pattern because they do not work in terrain like ours. We fasten underlayment and shingles on that exposure to a higher standard, using a six-nail pattern on shingles like GAF Timberline HDZ and checking fastening schedules against the manufacturer’s wind rating. If you are seeing granules in your gutters or shingles lifting on the downhill side, call (361) 320-9467 for a free inspection.
Expect the decking and underlayment underneath to need serious attention. Wood-shake roofs from that era were often installed over spaced board sheathing with no ice and water shield, and after 50-plus years under Lafayette’s oaks, the decking is frequently rotted in patches. We budget for decking replacement in writing before we start. The tear-off is also heavier and slower because wood shakes do not come off cleanly. Once the old roof is off, we inspect the sheathing, replace bad sections, lay solid underlayment with ice and water shield at valleys and penetrations, and then install your new roofing material. Most Lafayette homeowners choose fire-resistant architectural asphalt shingles or, if they want the traditional look without the fire risk, concrete or synthetic tile. Call (361) 320-9467 and we will walk you through the options with prices in writing.
Yes, a roof replacement in Lafayette requires a permit, and the permit triggers current building code requirements that your 1960s or 1970s roof probably does not meet. The most common triggers are edge metal at eaves and rakes, ice and water shield at all valleys and penetrations, balanced attic ventilation, and in some cases improved sheathing fastening. These are not optional once the permit is pulled. We handle the permit for you and we write allowances for code upgrades into the estimate, so you see those costs on paper before we begin, not as a surprise after the roof is open. For a question about your specific house, call (361) 320-9467.
Once a year, ideally in late September or October before the rainy season starts. Lafayette’s oak and redwood canopy drops leaves and needles continuously, and by November gutters and valleys are often packed with debris that dams water during the first storms. An annual inspection catches clogged valleys, cracked flashing, lifted shingles, and failing sealant before they become interior water damage. After a major windstorm, a second inspection is worth doing, especially on the downhill exposure. We do not charge for a storm damage inspection. Call (361) 320-9467 and we will put you on the schedule.
A free estimate is an on-site inspection and a written, line-item price for whatever work your roof needs. There is no charge for the visit. A roof coating is a specific product applied to a flat or low-slope roof to extend its life by sealing cracks and reflecting heat. During a free estimate, we may recommend a coating if your flat roof is a good candidate, but you are never obligated. The estimate costs nothing either way. Call (361) 320-9467 and we will come look.
