Pipe Boot
A rubber or metal collar that seals around plumbing vent pipes where they penetrate the roof. One of the most common sources of roof leaks when the rubber cracks.

Why Pipe Boots Matter for Insurance Claims
Pipe boots seal one of the most common roof penetrations: plumbing vent pipes. Every residential roof has at least one or two vent pipes, and each one requires a pipe boot. When the rubber deteriorates or is damaged by hail, the seal fails and water runs down the pipe into the interior. Pipe boots should be replaced during every re-roof and should be included as line items in the estimate. They are inexpensive individually, but omitting them leads to future leak problems.
Pipe Boots in Xactimate Estimates
Pipe boots appear in Xactimate as individual items under the RFG trade category. The count should match the number of plumbing vent penetrations on the roof. Standard pipe boots (rubber with an aluminum base) are the most common, but some installations use lead or all-metal boots. The pipe diameter (typically 1.5 to 4 inches for residential plumbing vents) determines the boot size. Each boot is a separate line item with its own quantity.
Pipe Boot Options
Standard rubber pipe boots are the least expensive option but have a limited lifespan. Higher-quality options include EPDM rubber boots (more UV-resistant), thermoplastic boots, and all-metal lead pipe flashings. In hail-prone areas, some contractors specify more durable pipe boot materials that resist impact damage. The estimate should reflect the boot type appropriate for the climate and the level of quality that matches the rest of the roofing system.
Frequently asked questions
Yes. Pipe boots are always replaced during a re-roof. They are a wear item with a limited lifespan (typically 10 to 15 years for rubber boots), and reusing old pipe boots on a new roof creates a guaranteed future leak point.
Pipe boots are estimated as individual items (each) in Xactimate. The line item includes the boot material and labor to install. Each plumbing vent penetration gets its own pipe boot. Count all vent pipes during the roof inspection.
The rubber gasket that seals around the pipe deteriorates from UV exposure, temperature cycling, and weathering. Over time, the rubber cracks, shrinks, and pulls away from the pipe, creating a gap where water enters. Hail impact can also crack or split the rubber collar.
