What repairs well
Pipe boots. The rubber collar around a plumbing vent dries out and splits at around twelve to fifteen years. It is responsible for a large share of the leaks we see, it leaks long before the surrounding shingle shows any sign of failing, and it is cheap to fix. If you have a leak and the shingles look fine, this is the first thing to check.
Flashing. Chimney, sidewall, step and kick-out flashing all loosen and lift over time. Reseating or replacing flashing is straightforward work and stops a leak that would otherwise rot decking for years.
A small number of blown or missing shingles. After a wind event, replacing a handful of tabs is normal and sensible.
Valley metal. Valleys carry the most water on the roof and the metal in them can be replaced without touching the rest.
Localised impact damage. A falling limb that punctured one area — common under the mature canopy in Richardson — is a repair, not a replacement.
When a repair is throwing money away
We will tell you this at the inspection rather than after you have paid for a patch:
- Brittle shingle. If it cracks rather than flexes when lifted, the crew cannot work on it without creating new damage around every repair.
- Damage across multiple slopes. Scattered hail bruising is not a patch job, and patching it can complicate a claim you were entitled to.
- Repeat leaks in different places. Three leaks in three seasons is a roof telling you something.
- Roof past about eighteen years. Money spent here is rent. It buys time, not life.
- Widespread soft decking. At that point the repair is a replacement with extra steps.
The thing nobody warns you about: colour match
A repair on a roof more than a few years old will not match. Shingle fades with UV exposure, manufacturers revise colour blends, and the granule mix changes between production runs. New shingle set into an aged slope reads as a patch from the street, and there is no way around it.
On a back slope nobody sees, that does not matter. On the elevation facing the street it might, particularly if you are selling. It is worth deciding which you care about before the work rather than being surprised by it — and it is one of the quiet reasons homeowners with an approved claim choose replacement over repair.
Finding the actual leak
Water does not fall straight down. It enters at a penetration, tracks along the underside of the decking or down a rafter, and appears on your ceiling somewhere else entirely — sometimes several feet away and on the other side of a wall.
Which is why a stain in the corner of a bedroom does not tell a roofer where to work. Finding the entry point means going into the attic and following the track back with the roof surface checked from above at the same time. A contractor who quotes a repair from a photo of your ceiling is guessing.
What repairs cost
Small repairs — a pipe boot, a few shingles, reseating a section of flashing — are typically a few hundred dollars. Larger work such as replacing valley metal or rebuilding chimney flashing runs higher. Anything involving decking replacement climbs quickly, because at that point the roof has to be opened.
Whether a repair is even the right call is what the free inspection answers. If the honest answer is that the roof is finished, you will get that answer, with photographs.
