A clearer plan for roof repairs.
A leak, missing shingles or damage around a skylight is a reason to investigate. It does not, by itself, tell you whether the answer is a targeted repair or a replacement. Start with a contractor who handles your roof type and can explain the inspection findings.
Give the contractor a useful starting point.
Describe where you see the issue, when it appears and whether it followed wind, rain or other changes. Include the approximate roof age if known. Photographs taken safely from the ground or inside can help; do not climb onto the roof to prepare an enquiry.
Ask for a diagnosis before agreeing to the repair.
The written scope should identify the suspected cause, the area to be repaired, materials and the limits of the proposed work. Ask what happens if underlying deterioration is discovered. If the recommended work is temporary, make sure the estimate explains that and the next step.
- What inspection findings support the recommendation?
- Does the scope include flashing, seals or adjacent roof components?
- What is excluded, and what could change the price?
- How will the contractor document the completed work?
Compare repair and replacement explanations.
If contractors disagree, ask each to explain their evidence and assumptions. A focused repair may address a local issue; it does not renew unrelated areas of the roof. A replacement recommendation should explain why a repair is inadequate for the condition observed.
Leaks and attic conditions are not always the same problem.
Natural Resources Canada explains how attic air sealing, insulation and ventilation relate to roof and ice-dam performance. This is useful background, but it does not diagnose your property. Ask a qualified contractor to investigate the actual cause.
