When to repair or replace a leaking roof

One leak does not settle the repair-or-replace decision. The roof's age, the area affected and the condition of the surrounding assembly matter.

Ask the roofer which parts of the roof still look serviceable and what the repair would address. If the proposal is for replacement, ask what broader conditions make patching a smaller area less practical.

If you need help finding the source of a leak or deciding what work to request, ask Dekoven Roofing for a roof assessment.

One leak is not the whole answer

A single leak on a roof in good shape may call for a targeted repair. A roof near the end of its service life, or one that has leaked repeatedly, may be a better candidate for replacement.

Compare three situations

• One isolated defect on an otherwise sound roof: repair is often reasonable.
• Several recurring problems in different places: ask whether the roof as a whole is failing.
• Known moisture damage in the decking or insulation: repair of the surface alone may not be enough.

Questions to ask

• Which parts of the roof still look serviceable?
• What exactly will the repair address?
• What would make a repair impractical?
• How old is the roof and what condition is the decking in?

If you are unsure, ask for a repair scope and a replacement scope so you can compare costs and what each covers.

Frequently asked questions

Is repair always cheaper?

Up front, usually. Over time, repeated repairs on a failing roof can cost more than replacement.
