Our Step-by-Step Roof Replacement Process

We follow a proven 6-step process to ensure your new roof is installed correctly and on schedule.

1. Free Roof Inspection & Estimate

We start with a thorough inspection of your current roof, attic, and structure. Our estimator measures your roof's square footage, checks for water damage or rot, and discusses material options. You'll receive a detailed written estimate within 24 hours—no pressure, no hidden fees.

2. Material Selection & Ordering

We help you choose from asphalt shingles, metal roofing, tile, or flat roofing systems. We order materials from local suppliers to avoid delays. Most materials arrive within 5–10 business days.

3. Tear-Off & Deck Preparation

Our crew removes old shingles, underlayment, and flashing. We inspect the wood deck for rot and replace damaged plywood (typically ½-inch OSB). We also install ice and water shield in valleys and eaves for extra leak protection.

4. Underlayment & Flashing Installation

We apply synthetic underlayment (30-lb felt or comparable) and install step flashing, chimney flashing, and pipe boots. All flashings are sealed with high-grade polyurethane caulk.

5. New Roof Installation

We install your chosen roofing material per manufacturer specifications. For asphalt shingles, we use 4 nails per shingle (6 in high-wind zones). For metal roofing, we use hidden fasteners and standing seams. We also install ridge vents, soffit vents, and attic fans as needed.

6. Final Cleanup & Inspection

We sweep the job site, use magnetic rollers to pick up nails, and run a final walkthrough with you. We also provide manufacturer warranties (25–50 years) and our workmanship guarantee.
