Roofing Specials in San Francisco, CA
If you’re looking at roofing costs in San Francisco, call (831) 318-8819 before you commit to anything. Brennan Roofing Co runs a small set of standing offers that make roof work easier to budget for, and we put every price in writing before any work starts. That means the number you’re quoted is the number you pay, whether it’s a repair in the Sunset or a full replacement in Bernal Heights. No door-knock surprises, no change orders hiding in the fine print. Here’s what’s on the table right now.
Styles & brands we work with
Current Offers
Free Roof Inspection with Any Repair
Book any roof repair, and we’ll inspect the entire roof at no charge while we’re up there. That includes checking flashing, decking, underlayment, and drip edge, so you’ll know if anything else is starting to fail before it leaks. The inspection report is yours to keep, whether or not you do additional work.
Valid through March 31, 2027. Mention this offer when you call (831) 318-8819.
No-Charge Revisit Within the 365-Day Done Right Promise
Every repair and installation we do is guaranteed in writing for one full year. If anything we touched fails during that period, we come back and make it right at no charge. This isn’t a coupon in the traditional sense, but it’s the most valuable offer we have, and it’s automatic on every job.
Valid through March 31, 2027. Mention this offer when you call (831) 318-8819.
Free Estimates, Written and Itemized
Every job at Brennan Roofing Co starts with a written, line-item estimate. You’ll see exactly what materials cost, what labor costs, and what the total is, before any work begins. Homeowners in Noe Valley, the Richmond, and across San Francisco tell us this is the part they appreciate most: the price on paper doesn’t move at the door.
Valid through March 31, 2027. Mention this offer when you call (831) 318-8819.
Senior and Military Courtesy
If you’re a senior or an active-duty or retired service member in San Francisco, let us know when you call. We apply a courtesy to your service and explain exactly how it affects your written estimate. It’s our way of saying thanks, without making a production out of it.
Valid through March 31, 2027. Mention this offer when you call (831) 318-8819.
Seasonal Fog-Belt Tune-Up
For homes in the fog belt, the Outer Sunset, the Avenues, and any street that stays damp half the year, we offer a seasonal maintenance check. We clear debris, inspect flashing and seals, and flag anything that looks like it won’t make it through the next winter storm. The written report shows what needs attention now and what can wait.
Valid through March 31, 2027. Mention this offer when you call (831) 318-8819.
First-Time Customer Courtesy
If you’ve never hired Brennan Roofing Co before, mention it on the phone. We’ll apply a first-time customer courtesy to your written estimate and walk you through exactly what it covers. You’ll still get the same written price, the same 365-Day Done Right Promise, and the same background-checked, uniformed technician on your roof.

How to Redeem
Getting the best price starts before we ever arrive on your roof in San Francisco. First, call (831) 318-8819 and tell the live person who answers which offer applies to you. Second, we’ll book a time for a background-checked, uniformed technician to visit and put together your written, line-item estimate. Third, present the offer when your technician arrives, and it gets applied to your written price before any work starts. No codes to enter online, no forms to fill out, no fine print you need a magnifying glass for. Just a live person on the phone and a number on paper.
Travis Oakley, owner at Brennan Roofing Co, runs the same Standard on every job, whether it’s a small flashing repair in the Mission or a full tear-off in Pacific Heights. The Garrison Standard and The Garrison Code govern how we work: every job begins with a written price, every technician is background-checked and in uniform, and every repair or installation is guaranteed in writing for one full year. If it’s not done right, we come back free. That’s the offer that never expires, and it doesn’t need a coupon.
Call (831) 318-8819 to schedule your free estimate. Mention any offer when you call, and we’ll put it in writing before any work begins.
