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 roof doesn’t ask for much. It just shows up every single day — through the heat, the rain, and the years — quietly doing its job. But even the best roofs have a lifespan. And when yours starts showing its age, the worst thing you can do is wait for a roof replacement.
At Crandall Roofing, we’ve been replacing roofs across Santa Rosa and the greater North Bay since 1995. Over 10,000 homeowners have trusted us to protect what matters most to them. We bring that same care, craftsmanship, and honesty to every roof we replace — because your home deserves nothing less.
This is the question we hear more than any other — and it’s a good one. Most homeowners don’t think about their roof until something goes wrong. But if your home was built before 1990, your roof has been working hard for a long time. And the truth is, by the time visible damage shows up, the roof has often been struggling for years.
The good news? You don’t have to figure this out alone. We’ll come take a look, give you an honest assessment, and help you understand exactly where your roof stands — no pressure, no upselling.
Your roof has a way of letting you know when it needs help. Here’s what to watch for.
These are the most common signs — but not the only ones. Every home is different, and some of the most significant roof issues aren’t visible from the ground. If something looks off, trust your gut and give us a call. We’ll take a look and tell you exactly what’s going on.
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.
Answer three simple questions, and we’ll help you figure out whether your roof needs attention — and what kind. It takes less than two minutes.
Every material we install carries a Class A fire rating — the highest level of fire protection available. In a region where wildfire awareness is part of daily life, that’s not a detail we take lightly. We work exclusively with trusted manufacturers such as Owens Corning, GAF, Malarkey, and CertainTeed, and we’re factory-certified to install their materials to exact specifications — which means your warranty is protected from day one.
Here’s a look at the roof replacement options we offer.
Asphalt shingles are the most popular roofing material in the North Bay — and for good reason.

We’ll talk through what we find, answer your questions honestly, and help you understand your options before any decisions are made.
Step 2: Customized Recommendation and Quote Based on what we find, we’ll put together a personalized recommendation for your replacement — including material options, a clear cost estimate, and a realistic timeline. No confusing jargon, no hidden fees. Just a straightforward picture of what your project involves.

Step 4: Expert Installation Our certified crew gets to work — removing old materials, inspecting and repairing any underlying damage, installing new underlayment, and carefully placing your chosen roofing material. Every step is done to manufacturer specifications, protecting your warranty and your investment.
Step 5: Final Inspection and Clean-Up When the work is done, we do a thorough final walkthrough to make sure everything meets our standards — and yours. We clean up completely, leaving your property exactly as we found it. Then we hand things back over to you with full documentation of your warranties.

Every home is different, so every replacement is priced differently. Factors such as the size of your roof, your chosen materials, and any underlying repairs needed all affect the final cost. Most residential replacements in the North Bay range from $5,000 to $15,000 or more for larger homes or premium materials. The best way to get an accurate number is to reach out — we’ll come take a look and give you a clear, honest estimate with no obligation.
Most residential replacements take one to three days, depending on the size of your home and the materials being installed. We’ll give you a realistic timeline during your consultation and do everything we can to minimize disruption to your daily routine.
Most asphalt shingle roofs last 20–25 years. Metal and tile roofs can last significantly longer. If your home was built before 1990 and you’re not sure when your roof was last replaced, that’s worth finding out. We can help determine the age of your existing roof system.
It depends on your roof’s age, the extent of the damage, and what’s going on underneath the surface. As a general rule, if your roof is over 20 years old or the damage is widespread, replacement is usually the smarter long-term investment. We’ll always give you our honest recommendation — even if it means telling you a repair is all you need.
A few simple things go a long way. Clear the area around your home so our crew has easy access. Remove fragile items from your attic and interior walls. And let us know if you have any specific concerns before we start — we want the process to feel as smooth and stress-free as possible for you.
Not necessarily. We’ll walk you through everything before we begin, so there are no surprises. Most homeowners prefer to be home on the first morning — but after that, our crew handles everything professionally and respectfully, whether you’re there or not.
Your replacement is backed by two layers of warranty protection — a manufacturer material warranty of up to 50 years on qualifying products, and our own workmanship warranty covering the installation itself. We’ll walk you through exactly what’s covered before we start.
Choosing the right roofing company makes all the difference — and we don’t take that lightly. Since 1995, over 10,000 North Bay homeowners have trusted Crandall with their most important home investment. We’d love the chance to earn your trust, too.
Reach out today, and let’s start the conversation. We’re here Monday through Friday, 8 AM to 4 PM — and always happy to help.
