How We Install Your Shingle Roof: A Step-by-Step Process We follow a systematic approach to every shingle roofing project. This process ensures quality, safety, and longevity. Step 1: Free Inspection and Estimate
We start with a thorough inspection of your existing roof. We measure every plane, check decking condition, and note any ventilation issues. Within 48 hours, you'll receive a detailed written estimate with material options and exact pricing. Step 2: Material Selection
We offer three tiers of asphalt shingles. Three-tab shingles cost $3.50 to $5.00 per square foot installed. Architectural shingles run $4.50 to $7.00 per square foot. Premium luxury shingles range from $7.00 to $10.00 per square foot. We'll help you choose based on your budget and desired lifespan. Step 3: Tear-Off and Deck Preparation
Our crew removes all old shingles, underlayment, and flashing. We inspect the plywood deck for rot or damage. Any compromised decking gets replaced with new 7/16-inch OSB or 5/8-inch plywood. This step typically takes one to two days for an average home. Step 4: Underlayment and Ice and Water Shield
We install synthetic underlayment over the entire roof deck. In valleys, eaves, and around penetrations, we apply a self-adhering ice and water shield. This provides a watertight barrier against Novato's winter rains. Step 5: Flashing Installation
We install new step flashing at all roof-to-wall intersections. We use galvanized steel or aluminum flashing at chimneys, skylights, and vents. Each piece is interlocked with the shingle course above. Step 6: Shingle Installation
Our crew installs shingles from the bottom up, following manufacturer specifications. We use four nails per shingle on standard slopes, six nails on steep slopes. Each course is offset by 6 inches for proper water shedding. We maintain a consistent 5-inch exposure. Step 7: Ridge Vent and Hip Installation
We install ridge vents along the peak for balanced attic ventilation. We use shingle-over ridge caps that match your shingle color. This ensures a clean, finished look. Step 8: Final Quality Inspection
Our project manager inspects every square foot. We check nail placement, sealant application, and flashing integrity. We clean all debris with magnets and leaf blowers. ## How Much Does Roof Replacement Cost in Novato? A typical shingle roof replacement in Novato costs $7,500 to $18,000 for most single-family homes. Your final price depends on roof size, pitch, material grade, and accessibility. Cost breakdown for a 2,000-square-foot home:
- Three-tab shingles: $7,000–$10,000
- Architectural shingles: $9,000–$14,000
- Luxury shingles: $14,000–$20,000 We also charge for deck repair at $75–$150 per sheet of plywood. Permit fees in Novato run $200–$500. We include dumpster rental and disposal in our estimates. What factors affect your cost?
- Roof pitch: Steeper roofs require more safety equipment and labor.
- Number of penetrations: More vents, skylights, and chimneys increase labor.
- Tear-off layers: Two layers of old shingles cost more to remove.
- Access: Tight streets or steep driveways may require crane delivery. ### How Long Does a Shingle Roof Replacement Take? Most residential shingle roof replacements take 3 to 5 days from tear-off to final cleanup. A simple ranch-style home with a low pitch might take 2 days. A complex roof with multiple valleys and penetrations can take 7 days. Weather delays happen. We schedule around Novato's rainy season (November through March) and will communicate any changes immediately. ## Why Choose Northbay Roofing Co for Your Shingle Roof?
