Start with the roof you actually have
A useful proposal begins with an assessment of your roof, including its covering, pitch, access, visible condition, and problem areas. Share when a leak occurs, whether repairs have been made, and whether you plan to add solar or replace a skylight. Those details can change the work required. A quote based only on floor area cannot explain all of these conditions.
San Rafael properties can present very different access conditions. A narrow driveway, hillside lot, attached garage, or landscaped courtyard can affect material delivery and debris handling. Ask where equipment will go and how the contractor intends to protect paths, plants, windows, and outdoor furniture.
Make each estimate describe the same work
Look for a named roof product and a description of the layers below it. Underlayment, perimeter details, starter material, ridge treatment, and flashing should be addressed alongside the visible roofing. If one estimate includes replacing metal flashings and another assumes reuse, the two totals represent different projects.
Ask how hidden deck damage will be handled once the old roofing is removed. A clear proposal explains how additional work is documented, priced, and approved. Request a distinction between included work, optional upgrades, allowances, and exclusions so that a lower starting price does not obscure an incomplete scope.
Compare the handover as carefully as the installation
The final stages matter: debris removal, ground cleanup, inspection arrangements where applicable, and documentation of the finished work. Ask who will communicate schedule changes and what happens if weather interrupts an open-roof stage. Discuss how temporary protection will be maintained.
Product coverage and workmanship coverage address different issues. Request the actual written terms, including registration responsibilities and exclusions. Keep the signed scope, change approvals, photos, product details, and warranty paperwork together. These records help you maintain the roof and explain its history to a future buyer.
