The first distinction
A roof leak is a symptom, not a complete scope of work.
Water may appear away from the entry point. Flashings, roof penetrations, transitions, drainage, underlayment, surface membranes, tiles, fasteners, and the roof deck can all matter. A useful estimate should explain what the contractor believes failed and what the proposed work does—and does not—address.
Repair and replacement signals
Make estimates comparable
- Which roof area and component is believed to be failing?
- Is the proposal a temporary stabilization, a localized repair, a coating or maintenance scope, or a replacement?
- What materials, preparation, underlayment, flashing, edge, penetration, and drainage work are included?
- What hidden conditions could change the price, and how will change orders be approved?
- Who obtains any required permit, and which inspections are included?
- What workmanship and manufacturer warranties apply, and what can void them?
Flat or low-slope roof questions
Ask the inspector to distinguish a surface-maintenance issue from a membrane, flashing, penetration, drainage, deck, or structural issue. A coating can be part of a valid maintenance or restoration scope, but the proposal should identify substrate preparation, repairs beneath the coating, product, coverage, cure conditions, drainage assumptions, and warranty.
Tile roof questions
Visible tile is only one part of the system. Ask whether the concern is broken or displaced tile, flashing, penetrations, battens, underlayment, deck, or another component. An estimate should state whether tiles will be removed and reset, replaced, or left in place and how color or profile matching will be handled.
