Call (650) 447-1464What Does a Complete Roof Replacement Involve?
A complete roof replacement is far more than laying new shingles over old ones. We remove the existing roofing down to the deck, inspect and repair the underlying structure, install new underlayment and flashing, and then apply your chosen roofing material. This comprehensive approach addresses hidden issues like rot, leaks, or inadequate ventilation that partial repairs cannot fix.
Signs You Need a Roof Replacement
Curling or Buckling Shingle Edges
When shingle edges curl upward or buckle, they lose their seal and become vulnerable to wind uplift and water intrusion. This is a clear sign the shingles have aged past their useful life.
Missing or Broken Tiles on Roof
For tile roofs, cracked or missing tiles expose the underlayment to moisture. In San Jose's climate, this can lead to rapid deterioration of the deck below.
Dark Streaks from Algae Accumulation
While primarily cosmetic, widespread dark streaks from algae indicate prolonged moisture retention, which can accelerate granule loss and reduce shingle lifespan.
Water Stains on Interior Ceilings
Stains on your ceilings are a sure sign of active leaks. If multiple areas are affected, the roof system has likely failed.
Material Options for San Jose Homes
We offer three primary material categories, each with distinct performance and cost profiles for San Jose's unique climate.
Owens Corning Duration STORM Asphalt Shingles
These premium shingles feature a thick, durable construction with SureNail® technology for enhanced wind resistance, and they resist algae growth with StreakGuard® protection. Ideal for suburban neighborhoods, they offer a 10-year StreakFighter® warranty and a lifetime limited warranty.
CertainTeed Landmark PRO Asphalt Shingles
Landmark PRO shingles are a top choice for their dimensional look and superior impact resistance. They are Class 4 impact-rated, which can lower insurance premiums, and come with a lifetime limited transferable warranty.
Monier Lifetile Concrete Roof Tiles
For a long-lasting, fire-resistant option, Monier Lifetile concrete tiles withstand San Jose's wildfire season and seismic activity. They are available in various profiles and colors, and can last 50+ years with proper installation.
Cost Ranges for Roof Replacement in San Jose
Roof replacement costs vary based on roof size, slope, material, and accessibility. As a general guide for San Jose homeowners:
- Asphalt shingles (standard): $6,000–$12,000 for a typical 1,500-2,000 sq ft home
- Premium asphalt (e.g., Duration STORM): $8,000–$15,000
- Concrete tile: $15,000–$30,000 or more, depending on tile type and structural reinforcement
These ranges include tear-off, disposal, underlayment, flashing, and labor. We provide free, detailed estimates after an on-site inspection.
Step-by-Step Roof Replacement Process
Our process ensures quality, safety, and minimal disruption to your daily life.
Step 1: Inspection and Estimate
We inspect your roof deck, attic ventilation, and existing structure. We then provide a written estimate with material options, timeline, and cost breakdown.
Step 2: Permitting and Preparation
We handle all permits. In San Jose, a building permit is required for roof replacement over 10 squares; structural changes need engineered drawings per CBC Chapter 16. We coordinate with the city.
Step 3: Tear-Off and Deck Repair
Our crew strips the old roofing, removes debris, and repairs any damaged decking, rafters, or sheathing. We also install new drip edge and flashings around chimneys, vents, and skylights.
Step 4: Underlayment and Installation
We install a high-quality synthetic underlayment for superior waterproofing. Then, we lay your chosen roofing material, following manufacturer specifications for nailing patterns and overlap.
Step 5: Final Inspection and Cleanup
We perform a thorough quality check, then schedule a final inspection with the city. Our crew cleans the job site daily and performs a magnetic sweep for stray nails.
Insurance and Warranty Information
We are fully licensed (CSLB Class C-39) and insured. All materials come with manufacturer warranties—typically 25–50 years for shingles, 50+ years for tile. We also offer a workmanship warranty covering installation defects for up to 10 years.
Local San Jose Climate Considerations
San Jose's Mediterranean climate presents unique challenges: algae and moss growth from coastal humidity, thermal cracking from extreme UV exposure, wind uplift damage during Santa Ana events, and granule loss from hail or debris impact. We address these by selecting materials with algae resistance, cool roof coatings for energy efficiency compliance, and seismic bracing for tile roofs in earthquake areas where available. Fire-resistant materials are required in wildfire zones, and we ensure compliance with all local codes.
