Our go-to architectural shingle. Algae-resistant, Class 3 impact rating, and a 130-mph wind warranty. Ideal for residential roofs in Walnut Creek and surrounding neighborhoods.
Premium architectural with deeper shadow bands for a dimensional look. Class 4 impact rating for maximum hail protection. We've installed this on dozens of homes in Alamo and Danville.
Designer laminate that mimics hand-split cedar. Class 4 impact, UL 2218 fire rating, and a 50-year limited warranty. A top choice for Lafayette and Orinda homeowners who want curb appeal without sacrificing durability.

Why Malarkey
Malarkey's rubberized asphalt handles the Bay Area marine layer better than standard shingles. Here's what that means for your home.
NEX Polymer technology flexes through freeze-thaw cycles — critical in Walnut Creek's hill neighborhoods where temperature swings stress standard shingles.
Impact-resistant Class 4 rating reduces insurance premiums for many Contra Costa homeowners — we document this for your carrier at no extra charge.
Malarkey's smog-reducing granules (Scotchgard Algae Barrier) stay cleaner longer in the coastal fog belt — fewer moss calls over your roof's lifetime.
We're a certified Malarkey installer, which means the manufacturer warranty transfers intact — not voided by a non-certified crew's install shortcuts.
Legacy and Vista shingles carry a 50-year limited warranty; our 10-year workmanship warranty stacks on top under license C-39 192109.
Malarkey's heavier mat weight (up to 27% more asphalt) is why we spec it on exposed ridge lines in Lafayette, Orinda, and Moraga — where wind-driven rain tests every seam.
We've been Malarkey-certified since 2015, and roofing Contra Costa since 2008 (license C-39 192109). Certification means factory training, access to genuine materials, and the ability to issue Malarkey's full warranty — not just our own. It's a mark of craftsmanship we've earned.
A lot of companies say they 'use' Malarkey. But only a certified installer can back your roof with the manufacturer's guarantee. Our crews install to Malarkey's exact specs — no shortcuts, no substitutes. That's why we can offer a 10-year workmanship warranty on top of it.

Customer Voice
After the last big storm, our old roof was done. The Walnut Creek crew put on a Malarkey Legacy shingle—handled the wind like nothing. That roof isn't going anywhere.
— John M., Lafayette
We went with Malarkey Vista for the algae resistance. Three years in, still looks like day one. No streaks, no moss. Exactly what we needed in Danville.
— Sarah T., Danville
Verified Reviews
Walnut Creek Roofers 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, Walnut Creek Roofers 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 Orinda. 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.
