Every roof tells a story. The storms it weathered. The summers it stood up to. The decades it spent quietly doing its job while life unfolded underneath. And like everything that’s been working hard for a long time, it eventually needs a little care.
That’s where we come in.
Since 1995, Crandall Roofing has been repairing roofs across Sonoma, Marin, and Napa counties. Over 10,000 Bay Area homeowners have trusted us with the roof above their heads. We’d be honored to be the team you call, too.
Whether it’s a leak that showed up after the last big storm, shingles that have started to lift, or wear that’s been quietly building for years, we’re ready to help.
Some of the most beautiful homes in Sonoma and Marin were built before the trends arrived — and they’ve held up because they were built to.
Crandall specializes in roofing for the homes that define our communities. The classic ranches. The mid-century gems. The character-rich properties that have weathered the decades deserve a roofer who treats them with the same care their owners do. We bring craftsmanship that matches your home’s caliber and a steady, professional approach from the first conversation forward.
Your home has been the constant. Let us be the team that keeps it that way.
Once you submit, we may reach out to you via phone, email, or text to fetch information, which you can opt out of at any time. We will never share your personal information with third parties for marketing purposes. Consent is not a condition of purchase. Message/data rates apply.
This is the question almost every homeowner asks us, and the honest answer is: it depends on the roof, the age, and what’s actually going on up there.
A roof in its early or middle years with isolated damage is usually a great candidate for repair. A roof from the 1970s, 80s, or 90s that’s seeing repeated issues may be telling you it’s nearing the end of its chapter — and a replacement could be the better long-term investment for your home’s value and your peace of mind.
We’ll never push you toward more work than you need. We’ll walk you through what we find, explain your options, and help you make the call that’s right for your home. If repair is the answer, we’ll get to it. If replacement is the smarter path, we’ll help you understand why.
Roofs come in many shapes, materials, and personalities. Ours is a team that knows them all.
The most common roof in the North Bay, and the one we see most often. We address missing or damaged shingles, granule loss, blistering, and flashing deterioration — using premium materials from Owens Corning, GAF, Malarkey, and CertainTeed. Each repair is performed with meticulous attention to detail, so vulnerable areas are reinforced, and your roof’s lifespan is extended for years to come.
Metal roofs are built to last, but loose fasteners, seam separation, panel damage, and corrosion can all cut a long life short. Our metal roof repairs address the surface issue and the underlying cause, so your roof keeps doing what it was built to do.
Clay, concrete, and slate tile roofs each have their own quirks and their own challenges. Cracked tiles, deteriorated underlayment, and compromised flashing are common as tile roofs age. Every tile repair we perform includes a thorough look at the surrounding areas, because tile damage rarely stays in one place.
Flat and low-slope roofs face challenges all their own: membrane tears, seam failures, ponding water, and deteriorated coatings. As factory-certified installers of Silicone Roof Coatings, we can extend the life of existing low-slope top-layer roofing services, often without a full replacement.
Composite shingles, polymer slate, and synthetic cedar shake offer the look of traditional materials with modern performance. Our synthetic roof repairs address current damage and reinforce vulnerable areas, so your roof’s longevity and protective qualities continue for many seasons to come.
Whichever material is over your head, we use Class A fire-rated systems, sourced from trusted nationwide and local distributors right here in Sonoma and Marin counties.
When you call us, here’s what you can expect.
We start with a careful look at what’s going on — not just the symptom, but the cause. We walk you through what we find in plain language, with no pressure and no surprises. We give you a clear, honest price up front (it’s our Simple Pricing philosophy: straightforward rates, no hidden fees). And once the work begins, our seasoned crew handles it with the precision and care that comes from 30 years of doing this in your community.
When we leave, your roof is stronger than we found it — and you have the peace of mind of knowing it was done right.
You can find a roofer almost anywhere. Finding a Diamond Certified one is a different story.
Diamond Certified is awarded only to companies that score above a strict quality threshold, measured through independent, third-party customer research and ongoing performance verification. It’s not a membership we paid for. It’s a reputation we’ve earned, one roof at a time.
When you choose a Diamond Certified roofer, you’re choosing a company that has been independently vetted on workmanship, customer satisfaction, and the kind of follow-through that holds up long after the work is done.
30 years in. Diamond Certified. Still treating every roof like it’s the only one we’ll do that week.
Some roof problems can’t wait. A storm-damaged roof, a sudden leak, a tree limb where it shouldn’t be. These are the moments when you need someone to pick up. We provide emergency roof repair for homeowners across the North Bay, and we’ll be there as quickly as we can with the materials, expertise, and steady hands the moment calls for.
If you’re in a roofing emergency right now, call (707) 744-3744.
30 Years in Your Community.
Since 1995, we’ve been the team Sonoma and Marin homeowners call when their roof needs care. Many of our customers were referred by their neighbors, and we don’t take that lightly.
Diamond Certified.
This isn’t a badge we bought. It’s earned through independent customer surveys and rigorous performance standards. It’s a signal you can trust before you ever pick up the phone.
10,000+ Roofs and Counting.
Over 10,000 Bay Area homeowners have trusted Crandall with the roof above their heads. Each one taught us something. Each one made us better.
Premium Materials, Built-In Warranties.
Every repair uses Class A fire-rated systems backed by manufacturer warranties of up to 50 years. We’re factory-certified to extend these warranties because we install the way the manufacturer intended — every time.
Manufacturer-Certified Installation.
We work with Owens Corning, GAF, Malarkey, CertainTeed, Gaco, Velux, Carlisle, Versico, and Duralast PVC. The names on your roof matter, so we use the ones that have earned their reputation.
Simple, Transparent Pricing.
No runaround. No hidden fees. Just an honest number from a team that’s been doing this the right way for three decades.

Roofs face a lot: wind, rain, hail, sun, the occasional falling branch, and the slow march of time itself. Age, original installation quality, and how regularly a roof has been maintained all play a role in how it holds up.
We repair and replace asphalt shingle, metal, tile, flat, and synthetic roofs — every common material in the North Bay. We’re factory-certified installers for the manufacturers we work with, including Owens Corning, GAF, Malarkey, and CertainTeed.
Yes. Some roof issues need immediate attention to prevent further damage to your home, and we’re set up to respond when those moments come.
That’s one of the most common questions we get, and the honest answer is that it depends on your roof’s age, the type of damage, and how widespread it is. We’ll give you a straightforward assessment and explain your options — repair, replacement, or a phased approach — so you can make the right call for your home.
A yearly look is a good rule of thumb, ideally in spring or fall before the next big season of weather. Catching small issues early is the easiest way to keep them from becoming big ones.
When a repair is performed by a factory-certified installer using approved materials, your warranty stays intact. That’s one of the reasons it matters who you call.
Your home has done a lot for your family. Let us return the favor for the part of it that’s been working hardest of all.
