Roof repair in Tampa

The stain on your ceiling is not under the hole

This is the first thing worth understanding about a roof leak, because it explains why so many repairs fail. Water entering at a penetration runs along the top of the decking until it meets a rafter, travels down the rafter until something stops it, and only then drops through the insulation onto the plasterboard. The visible stain can be several feet from the actual defect and frequently on a different slope of the roof entirely.

A repair that starts by sealing the area above the stain is a repair that will be back. Finding the entry point is most of the work; the fix itself is often twenty minutes.

Where Tampa roofs actually leak

In rough order of how often they turn up, and none of them are the middle of an open shingle field:

• Pipe boots. The rubber collar around a plumbing vent is the most weathered component on the whole roof, exposed to direct sun with nothing shading it. It hardens, splits at the base, and lets water straight into the deck. Boots reliably fail long before the shingles around them.
• Flashing at wall intersections. Where a roof plane meets a vertical wall, chimney or dormer, the joint is only as good as the metal and the sealant behind it. Sealant is a consumable, not a permanent fix.
• Valleys. Two slopes concentrating their runoff into one channel. Volume, velocity and debris all meet here.
• Broken seal strips. Wind lifts a shingle, breaks the adhesive bond, and lays it flat again. Nothing is visibly wrong. The next wind-driven rain goes underneath.
• Nail pops. Decking moves with heat and humidity, a nail backs out, and the shingle above it tents almost imperceptibly.
• Skylights. Usually the perimeter flashing rather than the unit itself, though older acrylic domes craze and fail in this sun.

What a competent repair looks like

The tell is whether the contractor opens anything up. A repair that consists entirely of sealant applied from above is a repair that treats the symptom. Boots are cut out and replaced, not caulked. Flashing is lifted and re-bedded, not smeared. Shingles around the defect are removed so the deck underneath can be looked at, because if the deck is soft the repair is not a repair.

You should get photographs. Before, during, and after. Any contractor working on a roof already has a camera in their pocket, and a refusal to document what they found is worth paying attention to.

When repairing stops making sense

Repair is very often the right answer, and this site would rather say so than sell you something larger. It stops being the right answer when:

• The decking beneath the leak is soft, delaminated or actively rotten — at that point you are replacing structure, not covering.
• The same slope has now been repaired three or four times in different places, which usually means the covering has reached the end of its service life and is simply failing wherever it feels like next.
• Granule loss is heavy across whole slopes and the shingles have gone brittle enough to crack when lifted. A brittle shingle cannot be repaired without breaking its neighbours.
• You are inside a year of replacing the roof for insurance reasons anyway, in which case the repair money is better kept.

Where the boundary between repair and replacement gets legally interesting is the state's 25% provision, which changes what a large repair triggers. That is covered in the 25% rule guide.
