Roof Leak Repair in Lewisville, TX
Tracing an active leak from the interior symptom back to the actual point of entry, then correcting it and showing you the before and after.
On a pitched roof the water almost never comes in directly above the stain. It lands somewhere uphill and travels along a rafter until something stops it, which is why a leak patched at the stain so often comes back.
Where the leaks actually come from
- Pipe boots that have split at the collar, the leading cause on any roof between ten and twenty years old.
- Step flashing and counter-flashing at wall intersections that was short, reused or sealed instead of woven.
- Valleys where debris has dammed water and pushed it sideways under the shingle course.
- Chimney flashing and crickets, or the absence of a cricket on a wide chimney.
- Skylight curbs and the seals around them.
- Fastener penetrations from satellite dishes, solar mounts, holiday lighting clips and previous repairs.
How we find it
- 1
We start inside, at the stain, and work out where the water is landing and which direction it is travelling.
- 2
We check the attic side where there is access, following the track back up the decking to the point of entry.
- 3
On the roof we inspect every candidate uphill of that point rather than patching the nearest suspicious thing.
- 4
We correct the source, photograph it before and after, and where there is any doubt we water-test the area before calling it done.
Why leak calls go wrong elsewhere
Sealant is not a repair.
A bead of roof cement over a symptom buys a season and hides the evidence for whoever comes next. Where a repair needs flashing, it gets flashing.
We look for the second one.
Roofs with one failed boot usually have several of the same age, and telling you about the other two now is cheaper for you than three more callouts.
The interior damage gets accounted for.
We will tell you plainly whether the ceiling, the insulation or the decking needs attention as well, even though that is not our invoice.
Questions we get about this work
Usually yes. Staining, rust tracks, damp insulation and daylight in the attic all leave a trail, and the roof-side evidence stays visible long after the drip stops.
Active leaks get priority in the schedule. Call and describe what you are seeing and we will tell you honestly when we can be there.
Yes, where the roof is safe to work on, as a temporary measure until the repair is done.
That depends on how long it has been going on. We photograph the interior evidence as part of the report so you have it if you decide to take it further.
Stop guessing where the water is coming from
We trace it from the stain to the source and show you the photographs at both ends. The evaluation costs nothing.
