The Roof Replacement Process, Step by Step

By Roof Replacement Specialists · 2026-09-12 · Roof Replacement Guide

Knowing what happens on your roof — and in what order — turns a stressful project into a straightforward one. Here is our exact process in Brea, from first call to final walkthrough.

Step 1: Inspection and detailed estimate

We inspect the roof, attic, and ventilation, take measurements and photos, and produce a written estimate with line items — not a single number. You will know exactly what is included and what optional.

Step 2: Material selection and scheduling

You choose material, color, and upgrades. We order materials, pull the CA permit, and schedule your project. Typical lead time is one to three weeks.

Step 3: Protection and tear-off

Landscaping, siding, and AC units get protected. The crew strips all old roofing to the deck in sections, keeping the site clean as they go.

Step 4: Decking inspection and repair

Every inch of exposed deck is inspected. Damaged sheathing is replaced at the pre-agreed per-sheet price, photographed for your records.

Step 5: Dry-in and flashing

Ice-and-water shield at eaves and valleys, synthetic underlayment everywhere else, new drip edge, and all new flashing at walls, chimneys, and penetrations.

Step 6: New roofing installation

Shingles, panels, or tile installed to manufacturer specifications — proper nailing patterns, exposures, and coursing. This is where craftsmanship shows.

Step 7: Ventilation, ridge, and finish work

Ridge vent or exhaust vents, ridge caps, final flashing details, and a complete magnetic nail sweep of your yard and driveway.

Step 8: Walkthrough and warranty registration

We walk the finished roof with you (photos included), register your manufacturer warranty, and hand over all documentation. Final payment only when you are satisfied.

Frequently Asked Questions

How much notice do you need to schedule?

Usually one to three weeks for standard projects. Storm seasons and specialty materials can extend that — book the inspection early even if you are still deciding.

Will the crew clean up every day?

Yes. We clean continuously during work and do a full magnetic sweep for nails at the end of each day and at project completion.
