Yes, its that fast. Plus, you wont have to worry about customer callbacks when the caulking fails and leaks.

I’m not sure how this can fit into my business. How are other roofers successfully using this product?
One large roofer has switched to a fixed-fee installation model. They bill their regular service charge, plus a flat fee for each Perma-Boot installed, easily increasing their per-job revenue over the typical standard hourly rates and materials markup. Another large roofer immediately installs the Perma-Boot on all new roof installations. They offer a ten year warranty on every roof, and are excited about no longer having to replace damaged pipe boots under warranty. They also no longer have to paint the white vent pipes.

Will PERMA-BOOT work for my home?
PERMA-BOOT can be installed on any home that uses standard 1-1/2 inch, 2 inch, 3 inch or 4 inch vent pipe boots on almost all roof pitches.

How does PERMA-BOOT protect my home?
PERMA-BOOT covers the existing vent pipe boot to prevent leaks that allow water to flow into your attic and cause water damage to the ceilings, interior walls, and sheetrock in your home.

How does PERMA-BOOT compare to a traditional pipe boot repair?
A traditional pipe boot repair is a temporary fix and lasts only as long as the new pipe boot or rubber gasket (about 3 to 7 years under normal weather conditions) before another repair is required. PERMA-BOOT is the only solution guaranteed to last for 30 years and does not require you to remove the old pipe boot or replace any shingles on your roof.

How does PERMA-BOOT compare to a metal boot flashing?
The problem with a metal boot flashing is that it still relies on a rubber gasket to seal it to the vent pipe. The rubberized seal is the most likely part to fail so a metal boot flashing does not really fix the problem. PERMA-BOOT covers the seal and prevents water from entering your attic at the vent pipe so it actually solves the problem.

How is PERMA-BOOT better than a lead vent pipe cover?
PERMA-BOOT is a straight-forward and affordable solution with minimal work involved. A lead boot with a cover is meant to last a long time, but it is more expensive and will most likely require hiring a professional to install it. The installation requires you to replace the old pipe boot and often the surrounding shingles as well.

Do I need to hire a contractor to install PERMA-BOOT?
If you can reach the vent pipe boot safely you can install the PERMA-BOOT without the use of additional tools or roofing tar. Simply slide the PERMA-BOOT over the top of the existing boot and you are done. A urethane sealant can be used at the base to help guard against high wind events and storm conditions if desired.

Will my old PVC pipe break while installing the Perma-Boot?
PVC pipe can become brittle from years of exposure, so handle it carefully. It could snap if you pull on it.

What if I have 1-1/2 inch PVC Pipe?
When installing the Perma-Boot on 1-1/2 inch (inside diameter) pipes, the boot will not fit snugly around the pipe. This is normal, the cap will secure the boot.

What if my PVC pipe moves around while installing the Perma-Boot?
If your PVC pipe moves downward while installing the boot, you may need to pull the pipe up while sliding the boot down so that the boot stays in contact with the roof.

Please read our list of Safety Warnings prior to installation.

How does the Perma Boot adjust to fit different roof pitches?
