Roof installation is the complete process of installing a new roofing system on a building structure, whether for new construction or as part of a complete roof replacement requiring tear-off of existing materials. Unlike simple roof repairs or overlay re-roofing, professional roof installation involves systematic construction from the roof deck up through the final protective layer, ensuring structural integrity, weather protection, and long-term performance.
A proper roof installation includes critical components: structural roof decking (plywood or OSB sheathing), waterproof underlayment barrier, ice and water shield in vulnerable areas, drip edge and flashing systems, primary roofing material (shingles, tiles, metal panels, or membrane), ventilation systems for air circulation, and final quality inspection. Each layer serves a specific purpose in protecting your home from water intrusion, weather damage, and thermal stress.
East Bay Roofers specializes in both new construction roof installation and complete tear-off replacement projects. Our licensed contractors (CA #987654) follow California building codes, manufacturer specifications, and industry best practices to deliver roofing systems engineered for the East Bay's unique climate challenges including seismic activity, coastal moisture, summer heat, and winter storms.
Installing roofing systems on newly built structures or additions. Starts with bare roof framing and includes deck installation, complete moisture barrier systems, and coordination with overall construction schedule. Ideal for:
Requires close coordination with general contractors, framers, and building inspectors. Allows optimal material selection without constraints of existing roof structure.
Complete removal of existing roof down to deck, followed by full installation of new roofing system. Recommended over overlay re-roofing for maximum performance and longevity. Best for:
Provides opportunity to inspect and repair deck damage, upgrade ventilation systems, and ensure full manufacturer warranty coverage. Required by most California jurisdictions for permit compliance.
Free on-site consultation to assess your project scope and needs. For new construction, we review architectural plans and coordinate with your builder. For re-roofing, we inspect existing roof condition, deck integrity, and structural considerations. We discuss material options including asphalt shingles, architectural shingles, tile (clay/concrete), metal panels, slate, and flat roofing membranes. Each option is evaluated for East Bay climate suitability, energy efficiency, fire rating, wind resistance, and aesthetic compatibility with your home's architecture.
We handle all building permit applications and coordinate with local building departments across 36+ East Bay cities. Permits ensure compliance with California Title 24 energy code, seismic requirements, fire safety standards, and local building ordinances. Required documentation includes structural calculations, energy compliance forms, material specifications, and installation plans. Typical permit processing takes 1-3 weeks depending on jurisdiction. Once approved, we schedule installation to align with your construction timeline or personal schedule.
Before installation begins, our crews protect your property with ground tarps, cover landscaping, set up debris collection systems, and establish safety perimeters. For occupied homes, we protect driveways, walkways, and vehicles. Safety equipment includes roof brackets, harnesses, scaffolding, and fall protection systems meeting OSHA standards. Materials are delivered and staged for efficient workflow. For tear-off projects, we rent dumpsters sized for complete material removal.
For re-roofing projects, complete removal of existing roofing materials down to roof deck. Systematic removal prevents deck damage and allows thorough inspection. We inspect all decking for rot, water damage, structural deficiencies, and proper fastening. Damaged sections are replaced with new plywood or OSB matching original deck thickness. Deck repairs typically add $200-$800 per sheet depending on access difficulty. This critical step ensures solid foundation for your new roof.
For new construction, installation of structural roof decking over rafters or trusses. We use 7/16" or 1/2" CDX plywood or OSB sheathing depending on rafter spacing and local code requirements. Proper deck installation includes 1/8" spacing between panels for thermal expansion, H-clips for panel support, and ring-shank nails for superior holding power. Deck must be properly fastened to prevent wind uplift and provide stable substrate for roofing materials.
Application of synthetic underlayment or felt paper as primary waterproof barrier. Synthetic underlayment offers superior tear resistance, UV protection, and walkability compared to traditional felt. We install ice and water shield (self-adhering waterproof membrane) in critical areas: eaves (first 3 feet), valleys, around chimneys, skylights, and roof penetrations. This creates secondary protection against ice dams, wind-driven rain, and leak potential. Proper underlayment overlap (6" side laps, 4" end laps) ensures continuous water barrier.
Installation of drip edge along roof eaves and rakes to direct water away from fascia and prevent deck rot. Metal flashing installed in valleys (open or closed valley method), around chimneys (step flashing and counter flashing), at roof-to-wall transitions, and around all penetrations (plumbing vents, bathroom fans, kitchen vents). Proper flashing is critical for leak prevention - most roof leaks occur at flashing failure points, not roofing material failure.
Installation of selected roofing material following strict manufacturer specifications for warranty compliance. Installation methods vary by material: Asphalt shingles installed with 4-6 nails per shingle, proper exposure (typically 5-5/8"), and offset pattern preventing water channeling. Tile roofing requires batten installation, proper overlap, and mechanical fastening in high-wind areas. Metal roofing demands precise panel alignment, concealed fastening, and thermal expansion accommodation. Each material has specific requirements for East Bay's climate and seismic activity.
Completion of ridge caps and hip shingles providing final weather protection along roof peaks and hips. Ridge vents integrated during this phase for continuous ventilation along roof peak. Proper ridge installation prevents wind uplift, water infiltration, and premature material failure. Hip caps require precise cutting and overlap for aesthetics and weather protection.
Installation of comprehensive ventilation system balancing intake and exhaust air flow. California code requires 1 sq ft of ventilation per 150 sq ft of attic space. System includes: Ridge vents for continuous exhaust along roof peak, soffit vents for intake air flow, proper baffle installation preventing insulation blockage, and powered attic fans if needed for large spaces. Proper ventilation reduces cooling costs 30%, prevents moisture accumulation, and extends roof life.
Thorough quality inspection by project supervisor checking installation quality, proper flashing, ventilation function, and adherence to specifications. Building department conducts final inspection verifying code compliance. We complete comprehensive cleanup including magnetic nail sweep (finds 99% of dropped nails), debris removal, gutter cleaning, and property restoration. All materials hauled to recycling facility when possible. You receive warranty documentation, installation photos, maintenance guide, and inspection certification.
