What is Roof Installation?

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.

New Construction Roofing vs. Re-Roofing

New Construction Installation

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:

  • Custom home construction
  • Residential developments
  • Room additions and second stories
  • ADU (Accessory Dwelling Unit) projects
  • Commercial building construction
  • Garage and outbuilding construction

Requires close coordination with general contractors, framers, and building inspectors. Allows optimal material selection without constraints of existing roof structure.

Re-Roofing (Tear-Off Installation)

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:

  • Roofs with existing damage or leaks
  • Homes with 2+ layers of shingles
  • Properties requiring deck inspection/repair
  • Upgrading to heavier materials (tile, slate)
  • Homes needing ventilation upgrades
  • Properties requiring insurance compliance

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.

STEP-BY-STEP PROCESS

Professional Installation Timeline

STEP 1

Initial Consultation & Design

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.

STEP 2

Permit Acquisition & Scheduling

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.

STEP 3

Site Preparation & Protection

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.

STEP 4

Tear-Off & Deck Inspection (Re-Roofing)

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.

STEP 5

Roof Deck Installation (New Construction)

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.

STEP 6

Underlayment & Waterproof Barrier

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.

STEP 7

Drip Edge & Flashing Installation

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.

STEP 8

Roofing Material Installation

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.

STEP 9

Ridge & Hip Installation

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.

STEP 10

Ventilation System Installation

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.

STEP 11

Quality Inspection & Cleanup

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.

YOUR QUESTIONS ANSWERED

Frequently Asked Questions

How much does roof installation cost?
Roof installation costs vary significantly based on roof size, material selection, complexity, and required repairs. For a typical 2,000 sq ft home in the East Bay: Asphalt shingles: $8,000-$12,000 (most economical option with 20-30 year lifespan), Tile roofing: $15,000-$25,000 (premium option with 50-100 year lifespan), Metal roofing: $12,000-$20,000 (40-70 year lifespan with energy efficiency), Flat roofing (TPO/EPDM): $10,000-$16,000 (commercial applications). All estimates include materials, labor, permits, warranty, and complete cleanup. Deck repairs, structural modifications, and complex architectural features add to base cost. We provide free detailed estimates with material options and pricing transparency.
How long does roof installation take?
New roof installation timeline depends on project size, material type, and weather conditions. Simple residential roofs (1,500-2,000 sq ft) typically take 3-4 days including tear-off, deck inspection, and installation. Larger homes (2,500-4,000 sq ft) require 5-7 days. Complex roofs with multiple levels, dormers, or valleys may take 7-10 days. Tile and slate installations take longer (7-14 days) due to material weight and specialized installation. Commercial projects scheduled in phases to minimize business disruption. Weather delays can extend timelines - we never rush installation in poor conditions. For new construction, we coordinate with your builder's schedule for seamless integration with other trades.
What's the difference between re-roofing and tear-off?
Re-roofing (overlay) installs new roofing materials over existing roof without removal. Advantages: Lower cost (saves 20-30%), faster installation, less debris. Disadvantages: Cannot inspect deck condition, limited to one existing layer, shorter warranty, added weight, conceals problems. Tear-off installation removes all existing materials to deck before installing new roof. Advantages: Allows deck inspection and repair, full manufacturer warranty, longer lifespan, required for tile/slate, meets building codes. Disadvantages: Higher cost, longer installation, more debris. We recommend tear-off for most projects because it reveals hidden damage, ensures proper ventilation, and provides longest-lasting results. Most California jurisdictions require tear-off for permit compliance.
Do you install roofs on new construction?
Yes, East Bay Roofers specializes in new construction roof installation for custom homes, residential developments, commercial buildings, room additions, and ADUs throughout the East Bay. We work directly with general contractors, builders, architects, and homeowners. Our new construction services include: Pre-construction consultation reviewing architectural plans and providing material recommendations, Permit acquisition handling all building department requirements, Schedule coordination aligning with construction timeline and other trades, Deck installation proper sheathing over rafters/trusses, Complete roofing system from underlayment through final inspection, Building code compliance ensuring all California requirements, and Final inspection coordination with building department. We understand construction scheduling challenges and maintain flexibility for weather delays and timeline changes.
What permits are needed for roof installation?
All new roof installations in California require building permits to ensure code compliance and safety. East Bay Roofers handles the entire permit process including: Building permit application with project plans and specifications, Structural calculations if required for heavy materials or structural modifications, Energy compliance California Title 24 forms for commercial projects, Fire rating documentation proving Class A fire resistance in wildfire areas, Ventilation calculations demonstrating proper air flow, and Inspection scheduling coordinating rough and final inspections. Permit costs typically range $200-$800 depending on jurisdiction and project scope. Processing time varies 1-3 weeks. Some cities have additional requirements like historical review or HOA approval. We navigate all requirements efficiently.
How do you ensure proper ventilation?
Proper roof ventilation is critical for roof longevity, energy efficiency, and moisture control. California building code requires minimum 1:150 ratio - 1 square foot of ventilation per 150 square feet of attic space (or 1:300 with vapor barrier). East Bay Roofers designs comprehensive ventilation systems including: Ridge vents providing continuous exhaust along roof peak, Soffit vents allowing intake air flow from eaves, Balanced air flow equal intake and exhaust preventing negative pressure, Proper baffles maintaining air channels and preventing insulation blockage, Gable vents supplementing air flow in complex roof designs, and Power vents if needed for large attic spaces. Benefits include: reduces cooling costs 15-30%, prevents moisture and mold, extends shingle life, prevents ice dams, and maintains comfortable interior temperatures.
