Pipe boot replacement on a roof insurance claim
Every plumbing vent penetration needs a new pipe jack (boot) when the roof is replaced, because the flange sits under the shingles and the old boot can't be reused. Adjusters often undercount them from the ground.
Why it gets left off
- —Penetrations on back slopes aren't visible from the street.
- —Boots are counted from a satellite view, which misses small vents.
- —Lead or split boots are treated as reusable.
The code or standard
IRC R903.2: flashing shall be installed around roof penetrations. Existing boots cannot be reused under new shingles.
How to measure it
A count of penetrations from your roof photos or the measurement report's penetration list.
Typical value on a 30-square roof
2 missed boots × $68.00/EA ≈ $136
National ballpark price. On a real claim ClaimGap uses the unit price from the carrier's own estimate.
What to put in the supplement
- One photo per penetration, labeled by slope.
- The count on the estimate versus your count.
Questions
- Can a boot be reused if it looks fine?
- The flange is nailed under the shingle courses, so it comes out with the tear-off. Code requires flashing around penetrations on the new roof.
