Does the warranty cover leaks?

Last updated October 28, 2026

Short answer

The warranty covers water penetration through the treated shingle. It does not cover a roof that was already leaking when it was assessed, because a leak is a repair job and repairs come before any treatment. What follows a treatment is surface failure, not a structural repair.

The covered case

The second thing the warranty names is water penetration through the treated shingle: water getting into the shingle the treatment was applied to, in a way the treatment ought to have prevented.

That is a claim about the surface, made against a roof that was sound and dry on the day it was treated. It is checked by the free inspection that starts the remedy.

The case it does not cover

A roof that is leaking is not treated. That is not a warranty position, it is the order of work: a treatment protects a surface that is still working, and a leak means the roof is not holding water out. The leak is fixed first, and if it points back to a roof at the end of its life, replacement is the honest answer.

Once a roof has been treated, a new leak is looked at rather than assumed. Where it enters decides whether it is a treated-surface matter or a repair.

Where leaks usually start

Most leaks are not in the middle of a shingle field. They start where the roof is interrupted: a chimney, a vent, a skylight, the flashing at a wall, or a valley where two planes meet and water concentrates.

Those are the places the assessment checks, which is also why the repairs list can matter more than the score on a roof that has active water entry.

  • Flashing at walls and chimneys
  • Vents, pipes and skylight surrounds
  • Valleys, where two roof planes meet
  • Missing, lifted or cracked shingles
  • Soft spots, which are a repair question before anything else

What to do if water appears

Start by sending us the details through the form: where the water is showing inside, and roughly where it lines up on the roof. The remedy begins with a free inspection for a reason, because the first question is always where the water is actually getting in.

If the inspection finds a repair rather than a treated-surface failure, that is what we will say.

The one question that decides it

Where is the water getting in? Everything about a leak claim follows from that answer, and the free inspection exists to establish it before anyone starts talking about cover.

Estimate where your roof sits

Two answers give an estimated zone and the coverage that comes with it. The measured Roof Health Score at the assessment decides the rest.
