Every quality roof replacement follows these five stages. Knowing the process protects you from contractors who skip steps.
Initial Consultation
Day 1–3
You call or request a quote online. A reputable contractor will ask about your roof's age, the type of issue you're experiencing, and your timeline. They'll schedule an in-person inspection—never trust a quote given over the phone without seeing the roof. This should be free. Any company charging for an initial consultation is the exception, not the norm.
Roof Inspection
Day 3–7
The contractor (or their estimator) physically examines your roof—climbing on it, checking the attic from inside, inspecting flashing, vents, and valleys. They're looking for: current damage, underlying structural issues, ventilation adequacy, number of existing shingle layers, and complexity factors that affect cost. A thorough inspection takes 30–60 minutes. If someone spends 5 minutes and gives you a quote, they're guessing.
Detailed Written Quote
Day 7–14
You receive a written proposal that should include: specific materials (brand, product line, color), labor costs, tear-off and disposal fees, permit costs, contingency pricing (e.g., cost per sheet for decking replacement), projected timeline, warranty terms, and payment schedule. Compare at least three quotes. The cheapest isn't always the best—look at the scope, materials, and warranty alongside the price.
Installation
Day 14–35 (1–5 days of actual work)
After you sign the contract, permit approval, and material delivery, installation begins. Your contractor should give you a specific start date and estimated completion date. During installation: expect noise from 7 AM–6 PM, brief periods without waterproofing during tear-off (why weather planning matters), and a dumpster in your driveway. A crew of 4–8 workers is normal for residential jobs.
Final Walkthrough and Documentation
Day of completion
When installation is complete, walk the property with your contractor. Check: the roof's appearance from ground level, gutter cleanliness, yard cleanup (magnetic nail sweep should be done), flashing details, and attic interior for any issues. Receive: warranty certificates (both manufacturer and workmanship), permit documentation, proof of inspection (if applicable), and before/after photos. Don't make the final payment until you're satisfied with the walkthrough.
