Repair cost begins with diagnosis
A water stain does not necessarily sit directly below the roof defect. Water can travel along decking, rafters or penetrations.
Common repair categories
| Repair type | Scope question |
|---|---|
| Damaged covering | How much surrounding material must be removed? |
| Pipe/vent flashing | Is the flashing or surrounding roof damaged? |
| Wall/chimney flashing | Can the detail be rebuilt locally? |
| Valley leak | What layers must be opened and restored? |
| Deck damage | How much sheathing or framing is affected? |
Small repairs still have setup cost
Travel, access, diagnostic time, materials and warranty responsibility mean tiny repairs do not always scale neatly by square foot.
When to evaluate replacement
If repairs recur, multiple areas are failing or the roof is near the end of its service life, compare with the repair-versus-replacement guide.
