About Owens Corning
We’re proud to be a certified Owens Corning installer serving Novato and the North Bay. Since 2007, we’ve installed hundreds of Owens Corning systems on homes across neighborhoods like Ignacio and downtown Novato. Their Duration® shingles give you the strength to handle our coastal winds and fog.
Every Owens Corning roof we install comes with a 25-year workmanship warranty on top of the manufacturer’s coverage. We back that with our own crew’s hands-on experience—no subs, no shortcuts. It’s how we’ve earned a 4.9 Google rating from over 120 reviews.

Product Lineup
We've been installing Owens Corning roofs across Novato since 2007, and we know these shingles inside and out. From the classic durability of Duration STORM to the premium look of Berkshire™, we'll help you pick the right collection for your home.
Our go-to for North Bay weather. Reinforced with SureNail® Technology for wind resistance up to 130 mph. We've used this on dozens of homes in Indian Valley and Ignacio — stands up to our coastal fog and sudden downpours. Backed by a limited lifetime warranty.
A solid mid-range option with a classic look. Features algae resistance and a 30-year limited warranty. We recently installed this on a bungalow on Grant Avenue — clean lines, great value, and the homeowners love the curb appeal.
Premium laminated shingles with a handcrafted, dimensional look. Thicker than standard shingles, with a 50-year limited warranty. We put this on a custom home near Mount Burdell last year — the depth and shadow effect are something else.
Our synthetic slate option for that high-end, natural slate look without the weight or cost. Perfect for historic homes in Old Town Novato. We've done three Truslate roofs on Sherman Avenue alone — fire-resistant, lightweight, and stunning.
Owens Corning Roofing Pricing
We keep our pricing straightforward for Owens Corning installations. As a certified installer, we give you a clear breakdown of costs for materials, labor, and any extras, so you know exactly what you're paying for.
Full Owens Corning roof replacement starts at $8,500 for a standard 2,000 sq ft home, including premium Duration Shingles.
Add-ons like ice and water shield or synthetic underlayment are itemized separately, typically $800 to $1,500 extra.
Labor costs are flat-rate per square foot, not hourly, so there are no surprises during the job.
All estimates are free and no-obligation. Final pricing depends on your roof's size, pitch, and condition. We'll walk you through every line item before work begins.
Why Owens Corning
We’ve installed Owens Corning roofs across Novato for years because they stand up to our North Bay weather—hot sun, heavy rain, and wind. Here’s what makes them a top choice for your home.
Owens Corning shingles resist heat and UV damage, perfect for our sunny North Bay summers. We’ve seen them hold up on homes near the Novato Creek for over a decade.
With Class H wind resistance, these roofs handle gusts that roll through Hamilton and Bel Marin Keys. No worries during winter storms.
Cool Roof technology reflects more sunlight, keeping your attic cooler and cutting energy bills. We’ve recommended it on homes near San Marin Drive for lower AC costs.
Every Owens Corning roof we install comes with a 25-year workmanship warranty from us, plus their own limited warranty. Peace of mind for your Ignacio or downtown Novato home.
Owens Corning shingles are tested for impact resistance, so they stand up to falling branches or hail. We’ve used them on roofs near Mount Burdell for years with zero issues.
We’re Owens Corning certified—meaning we’re trained to install their products right, every time. That’s the difference between a roof that lasts and one that doesn’t.
When we say we're a certified Owens Corning installer, it means we've passed their strict training and quality checks. Not every roofer can say that. It's a promise you're getting a roof backed by the manufacturer's own standards, not just our word.
We've been installing Owens Corning systems since 2007, and we stay current on their latest techniques. That certification means your roof comes with full warranty protection, from us and Owens Corning. It's peace of mind for your Novato home.
Our Certifications

Customer Voice
We had North Bay Roofing Co. install Owens Corning Duration® shingles on our Grant Avenue home last fall. They walked us through every step, explained the SureNail® technology, and the roof handled this winter’s storms like a champ. We finally have peace of mind.
— Mike & Linda, Novato
After a tree branch damaged our roof during that big windstorm, North Bay Roofing Co. came out same day. They recommended Owens Corning Cool Series® for our ranch-style house on Redwood Boulevard. The energy savings are real, and the crew left the yard spotless. Straight-up good work.
— Diane, Petaluma
Verified Reviews
North Bay Roofing Co. replaced our 22-year-old shingle roof in two days flat. The crew was respectful of our landscaping, cleaned up every nail, and the GAF system they installed looks incredible. The price was fair and they filed the permit without us having to chase it. Will absolutely call them again.
After a winter storm tore off two sections of our flashing, North Bay Roofing Co. was on-site within 24 hours. They tarped the exposed decking that same afternoon, walked us through the insurance claim process, and had the permanent repair done by end of week. Honest estimates, no upsell pressure.
I called for a pre-purchase inspection on a home in Petaluma. The inspector found two soft spots the listing agent hadn't mentioned, documented everything with photos, and gave me a written repair estimate I could use in negotiations. Saved me thousands.
