Are you choosing a new asphalt shingle roof for an East Bay or South Bay home? Done right, an architectural shingle roof is quiet, clean, and a strong value for the climate. Done wrong, it leaks at the first valley.
We install laminated shingles over synthetic underlayment, with extra waterproofing in the places Bay Area rain actually finds.
If this is the work your home needs, call (925) 722-6494 or send the form for a written estimate. There is no obligation.
Why shingle roofs leak at valleys and flashing
Water concentrates in valleys, at walls, and around pipes. A staple-only install leaves those spots thin. We add extra waterproofing in valleys and eaves, use metal or woven valleys as the roof needs, and replace pipe seals so the first hard rain does not find a gap.
How long architectural shingles last here
A quality laminated shingle on a ventilated roof often runs 20 to 30 years in the Bay Area, depending on sun, trees, and maintenance. Inland heat and heavy shade both shorten that life. We talk through color and ventilation when we estimate.
What a shingle replacement typically costs
Many Bay Area asphalt shingle replacements fall between about $9,000 and $28,000, depending on size, pitch, and access. We use recognizable manufacturers such as GAF when the spec calls for them. Cooler colors help on inland roofs.
What shingle roofing includes

Shingle roofing questions
How long do architectural shingles last here?+
A quality laminated shingle on a ventilated roof often runs 20 to 30 years in the Bay Area, depending on sun, trees, and maintenance. We inspect your current roof before we recommend a full replacement.
Can you overlay new shingles on the old ones?+
Sometimes, if the wood is sound, there is only one layer, and local code allows it. A tear-off is the better long-term job when the wood or underlayment is tired. We tell you which option fits.
Do you use GAF or other name-brand shingles?+
We use recognizable manufacturers such as GAF when the spec calls for them. We will show you the product and color before we order.
Are architectural shingles a good choice in the East Bay?+
Yes, for most neighborhood homes. They handle sun and rain well when the underlayment and flashing are done right. We can also talk through tile or metal if those fit the house better.
