What Roof Replacement Involves

A full replacement is not a repair. It is a complete rebuild of your home's first defense against the elements. We start with a tear-off—stripping every old shingle, underlayment, and flashing down to the deck. This exposes the wood so we can spot rot, decay, or sag that a patch job would simply hide.

The new system we install uses GAF Timberline HD architectural asphalt shingles or Owens Corning Duration premium shingles—both carry Class A fire ratings required by California Building Code 1505.2.1. Underneath, we lay a synthetic underlayment that resists tearing better than old felt, plus self-adhered ice-and-water shield in valleys and along eaves. Ridge vents at the peak let hot attic air escape, which cuts summer cooling costs.

Every shingle goes down with ring-shank nails, which grip the deck far better than smooth nails in high winds. We start with a starter course along the eaves, then work up in staggered courses so water sheds off each row instead of seeping between them.

Signs You Need Roof Replacement

Your roof will tell you when it is done. Shingles curling upward at the edges, granule loss that leaves bare spots, and asphalt cracking from thermal cycling are all end-of-life wear. Granules accumulating in your gutters mean the protective coating has eroded—your shingles are now baking in the sun instead of reflecting it.

Water stains on bedroom or attic ceilings are a late-stage warning. Once moisture wicks through the deck, rot spreads quickly. If you can see daylight through gaps in the roof deck, the structure itself is compromised. San Ramon's hot, dry summers stress materials relentlessly, and our occasional heavy winter rainstorms expose every weakness at once.

Our Roof Replacement Process

Step one is a free inspection. We climb up, photograph everything, and give you a written report—no pressure, just facts. If you decide to proceed, we pull the required permit from Contra Costa County. A roofing permit is mandatory before any replacement begins, and we handle it.

On tear-off day, a crew strips the old roof, inspects the decking, and replaces any rotted or sagging wood. We then install the new underlayment, flashing, and shingles, working in staggered courses for maximum water shedding. We back-nail every shingle where code requires, and we hand-seal any exposed fasteners. At the end, we run a magnetic nail sweep across your yard to catch every stray fastener, and we haul away all debris—including dump fees.

Cost Considerations in San Ramon

Roof replacement runs $450 to $700 per square (100 square feet) for architectural asphalt shingles, depending on pitch, accessibility, and deck repairs. A typical 2,000-square-foot home lands between $9,000 and $14,000, plus permit fees. If we find rotten decking under the old roof, that adds $200 to $400 per sheet—but it is far cheaper to fix it now than chase leaks later.

Warranty & Insurance

GAF and Owens Corning both offer 25-to-50-year manufacturer warranties, but only if the system is installed by a certified contractor and registered with the manufacturer. We handle that registration for you. If you are replacing a storm-damaged roof, we document everything for your insurance claim—photos, measurements, and a detailed scope of work—so you get fair treatment.

Signs You Need Roof Replacement

⚠

Curling Shingles

Shingles curling upward at the edges are losing their grip after years of thermal cycling. San Ramon's hot afternoons and cool nights make the asphalt expand and contract until the seal breaks.

⚠

Granules in Gutters

Granule loss from intense California summer UV means the protective coating is eroding. Check your downspout splash pads—if you see black sand, your shingles are aging fast.

⚠

Water Stains on Ceilings

Water stains on bedroom or attic ceilings are a sign that moisture is wicking through the deck. By the time it shows inside, the rot may already be spreading.

⚠

Daylight Through the Deck

Visible daylight through roof deck gaps is a structural emergency. If you can see sky from your attic, the deck has deteriorated and a full replacement is the only safe fix.

⚠

Wind Damage

Wind damage from Santa Ana desert winds can lift and split shingles, leaving exposed fasteners. A single missing tab lets water seep into the underlayment and rot the deck.

⚠

Salt Corrosion

Salt corrosion of metal fasteners is common even in San Ramon, where foggy mornings carry coastal moisture. Rusted nails lose their grip, and shingles start to slide.
