What Shingle Roofing Involves
Asphalt shingle roofing is the most common residential system in San Ramon, covering homes from the 1970s Spanish-style stucco in Country Club Estates to modern two-story tract homes near Norris Canyon. The work involves removing your old shingles down to the deck, inspecting and repairing any rotted plywood, installing synthetic underlayment (we use GAF Deck-Armor or similar), then laying new shingles with proper nail patterns and flashing at all penetrations. We offer three material tiers: 3-tab shingles (basic, 25-year life), architectural shingles like GAF Timberline HDZ (dimensional look, 50-year life, 130 mph wind warranty), and designer/luxury shingles like CertainTeed Landmark Pro (slate or wood appearance, 50-year life with algae resistance). For San Ramon's hot, dry summers and occasional heavy winter rainstorms, we recommend architectural shingles with an algae-resistant granule coating—this prevents the black streaks you see on older roofs in foggy mornings with coastal moisture.
Signs You Need Shingle Roofing
Your shingle roof needs replacement when you notice missing or curled shingles after a wind event—we see this in Windemere and Canyon Lakes after our occasional hail storms. Granules collecting in your gutters is another clear sign; those granules protect against UV radiation from our 486-foot elevation sun exposure. Attic moisture stains or daylight visible through decking from inside mean the shingles have failed. Ridge sagging indicates structural deck issues that we address during replacement. If your roof is over 20 years old and shingles are brittle or cracking from hot summer stress, it's time to replace. We also see algae discoloration on north-facing slopes in Alcosta due to morning fog—our architectural shingles include algae-resistant warranties.
Our Shingle Roofing Process
Our process starts with a free inspection and photo damage report—we document every issue on your roof, from curled shingles to flashing gaps. Step two is a material consultation: we show you samples of architectural vs. designer options, explain wind ratings (130 mph for GAF Timberline HDZ vs. 110 mph for 3-tab), and help you choose a color that matches your home's style in Bollinger Canyon or Country Club Estates. Step three is the installation: we tear off the old roof, inspect the deck, replace any rotted plywood, install synthetic underlayment, then nail new shingles using a six-nail pattern per shingle for wind resistance. We also install new step flashing at walls and pipe boots, and ridge vent for attic ventilation. Step four is cleanup with a magnetic nail sweep—we pick up every stray nail from your yard and driveway. Step five is final inspection and manufacturer warranty registration, typically within 2-3 days for a standard 2,000-square-foot home.
Cost Considerations in San Ramon
Shingle roof replacement in San Ramon typically costs between $7,500 and $18,000 for a standard single-story home, depending on square footage, material choice, and complexity. We price per square (100 square feet): 3-tab shingles run $350-$450 per square, architectural shingles $450-$600 per square, and designer shingles $600-$800 per square. Labor adds $150-$250 per square. Additional costs include deck repair ($500-$2,000 if rot is found), permit fees (typically $200-$400 from Contra Costa County), and dump fees for old material (included in our quote). We provide a flat-rate quote with no hidden fees—you'll know the exact cost before we start. For custom estate homes on large lots in Country Club Estates, expect higher costs due to steep slopes and complex valleys.
Warranty & Insurance
Our shingle roofs come with manufacturer warranties: 25-year limited on 3-tab shingles, 50-year limited on architectural and designer shingles from GAF, Owens Corning, and CertainTeed. These cover manufacturing defects like granule loss, cracking, and algae discoloration. We also provide a 10-year workmanship warranty on our installation—if a nail pops or flashing leaks due to our work, we fix it at no charge. For storm damage claims, we handle the insurance process: we inspect after hail or wind events, document damage with photos, and provide a written estimate your adjuster can use. We work with all major insurers and can coordinate the claim from start to finish. Our liability insurance covers any accidental damage during installation.

Signs You Need Shingle Roofing
Missing or Curled Shingles
After a wind event in San Ramon, you may notice shingles that have lifted or blown off entirely. This exposes your roof deck to our winter rainstorms, leading to interior leaks.
Granules in Gutters
Finding black sand-like granules in your downspouts means your shingles are losing their UV protection. Our hot summers accelerate this wear, reducing shingle life.
Attic Moisture Stains
Water stains on attic rafters or insulation indicate a failing shingle system. This is common in older homes in Country Club Estates after heavy rain.
Daylight Through Decking
If you see light coming through your attic roof boards, the shingles have deteriorated completely. This requires immediate replacement to prevent structural rot.
Ridge Sagging
A drooping ridge line on your roof signals decking failure, often from years of San Ramon's foggy mornings trapping moisture. We replace damaged plywood during shingle installation.
Algae Discoloration
Black streaks on north-facing slopes in Canyon Lakes are caused by algae feeding on limestone filler in old shingles. Our architectural shingles include algae-resistant warranties.
