Preventing Leaks and Water Damage Through Roof Maintenance
A well-maintained roof is one of the most important aspects of protecting your home from the elements. It acts as
Your home in Mill Valley has stood through decades of foggy mornings, sun-soaked afternoons, and quiet nights tucked beneath the redwoods. The roof above it has been there for every one of those moments, keeping your family dry, safe, and warm. But roofs grow older, just as we do. And when yours starts showing its age, you deserve a roofing company that treats your home with the same care you’ve poured into it for years.
That’s where Crandall Roofing comes in. Since 1995, we’ve protected homes across Sonoma and Marin Counties, including the unique craftsman cottages, mid-century homes, and hillside retreats that make Mill Valley one of the most beloved communities in the Bay Area. We’re not just here to install a roof. We’re here to help you protect what’s underneath it.
Many Mill Valley homes were built during the era of bell-bottoms and station wagons — and a lot of those original roofs are still hanging on. If yours is starting to show wear, we’d love to take a look. Our team specializes in helping longtime homeowners decide what comes next, with no pressure and no upsell.
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.
Every home in Mill Valley tells a story, and every roof has its own chapter to add. Our roofing services are built around the homes and homeowners we serve; protecting what you’ve built, while honoring the character that makes your house yours.
From a small repair to a full replacement, our crew handles each project with care, precision, and respect for your time. Below are the core roofing services we provide for Mill Valley homeowners.
A roof replacement is one of the most meaningful investments you can make in your home. When the existing roof has reached the end of its life, replacing it restores protection, beauty, and peace of mind all at once. We use Class A fire-rated materials and offer factory warranties up to 50 years, giving you confidence that your roof will protect your family for decades.
New roof construction calls for a steady hand and a clear plan. Whether you’re building a new home in Mill Valley or adding on to an existing one, our team brings the experience to get the structure right from the first nail. We work closely with you to choose materials such as asphalt shingles, tile, metal, or synthetic, matching your home’s character and your long-term goals.
Sometimes a roof doesn’t need replacing. It just needs a thoughtful repair from someone who knows what to look for. Our roof repair services address leaks, missing shingles, storm damage, and the smaller issues that, left alone, become bigger ones. We’ll give you an honest assessment and a clear path forward, whether that’s a quick fix or a longer conversation about what your roof really needs.
A well-maintained roof can outlast its expected lifespan by years, and the right care along the way protects both your home and your investment. Our roof maintenance services help Mill Valley homeowners stay ahead of small issues before they become expensive ones, with thorough inspections and honest guidance from our team. Whether your roof is approaching middle age or already wearing the badges of decades on the job, regular maintenance keeps it doing what it does best.
A roof and its gutters work as one connected system — when one falls behind, the other carries the burden. Our gutter services help Mill Valley homeowners protect their roofline, fascia, and foundation by keeping water moving where it should. From new installations paired with a fresh roof to replacing tired, sagging gutters that have served their time, we handle the work with the same craftsmanship we bring to every project.
Mill Valley business owners deserve the same quality and care we bring to every residential project. Our commercial roofing services cover flat and low-slope systems, working with trusted manufacturers such as Carlisle, Versico, Gaco, and Duralast PVC. We’re factory-certified installers of Silicone Roof Coatings, which can extend the life of an existing low-slope roof, saving you the cost and disruption of a full replacement when it isn’t needed yet.
Diamond Certification isn’t something a company can buy. It’s awarded only to contractors who score above 90% in independent customer surveys every single year. That means hundreds of real Mill Valley-area homeowners have been called, interviewed, and asked one question: Would you hire them again?
Their answer is the reason we’ve kept the rating year after year. When you choose Crandall, you’re choosing a company your neighbors have already vouched for.
You’ve raised a family under that roof. Hosted holidays, weathered hard seasons, and built a life within those walls. Through every chapter, your home has done its quiet work, sheltering the people and memories that matter most. Now, as your roof grows older alongside you, it deserves the same kind of care it has given for so long.
We understand that homeowners in Mill Valley aren’t looking for a quick patch or a flashy sales pitch. You want a roofer who respects the home you’ve built and the life inside it. Someone who’ll handle the job with skill, leave the property cleaner than they found it, and treat your time as carefully as your investment. That’s the standard our crew has held for thirty years, and it’s the reason longtime Bay Area homeowners keep recommending us to their neighbors.
A roof should last. That’s why every Crandall installation is backed by manufacturer warranties of up to 50 years — protection you can count on long after the work is done. Our Diamond Certification means our craftsmanship has been verified by independent reviewers and thousands of real customer ratings.
We use only Class A fire-rated roofing materials sourced from trusted national and local distributors. Combined with factory-certified installation, this gives Mill Valley homeowners the assurance that their home and family are protected, not just today, but for the next chapter of their home’s life.
A new roof is a meaningful investment, and we believe it should be accessible without adding stress to your life. That’s why Crandall partners with Hearth to offer flexible financing options designed around real homeowner budgets.
With Hearth, you can explore monthly payment plans that fit your situation. No hidden fees, no pressure, just clear numbers. Many of our Mill Valley customers find that financing makes it easier to choose the materials and protection they truly want, rather than settling for less.
The cost of your roof replacement will vary based on the size of your home, the pitch and complexity of the roof, and the materials you choose. An asphalt shingle replacement sits at a different price point than a tile or metal system, for example. Rather than quoting a generic range, we’d rather walk your roof, listen to your goals, and give you honest numbers based on your home, not someone else’s.
It can. Many homes in Mill Valley were built decades ago, and older roof structures sometimes reveal surprises once the existing layers come off: older underlayment, outdated flashing, or framing that needs attention. Our crew has been working on Marin County homes since 1995, so we know what to look for and how to handle it without dragging out the project or inflating the cost.
Most residential roof replacements wrap up in two to three working days, depending on the home’s materials and the complexity of the roofline. Homes with steep pitches sometimes take a bit longer. We’ll give you a realistic timeline up front and keep you updated throughout the project.
Yes — and often more than homeowners expect. A new roof signals to future buyers that the home has been well cared for, removes a major item from inspection reports, and protects everything beneath it. For Mill Valley homeowners thinking long-term, a quality roof is one of the most reliable investments you can make in the property.
The right material depends on the style of your home and how long you want the roof to last. We work with asphalt shingle, tile, metal, flat, and synthetic systems from manufacturers such as Owens Corning, GAF, Malarkey, CertainTeed, Gaco, Velux, Carlisle, Versico, and Duralast PVC. During your consultation, we’ll talk through which options fit your home’s character and your budget.
Your roof protects everything you’ve worked hard to build. Don’t wait until a small problem becomes a costly disaster. Whether you’re concerned about aging shingles, recent storm damage, or you simply want to know where your roof stands, we’re here to help. Our expert roofing contractors will assess your roof’s condition, explain what we find in terms you can understand, and recommend solutions that fit your needs and budget.
We’re available Monday through Friday, 8 AM to 4 PM, ready to bring our expertise to your Napa property. Time affects every roof eventually—but with the right care and attention, you can protect your home for years to come.
