 Pipe Collar Repair: Pipe
collars are the flashings that surround the plumbing vent pipes that extend through a home's
attic area and rise above the roof. There are two basic types:
- Neoprene/aluminum - Premium Quality
- Rubber/plastic - Budget Quality
Neoprene/aluminum premium quality pipe collars can last up to ten
(10) years -- The plastic type may last six (6) or seven (7) years if you're lucky.
Plastic pipe collars tend to expand and contract much more than the aluminum type, often
causing problems with adjoining shingles -- and contributing to premature roof
leaks.
It's a good idea to have a professional roofer check your pipe
collars every few years as they are the number one cause for home roof leaks. Home
Restorations' Md Roof Repair Program is a
great, inexpensive way to take care of several leaky pipe collars all at one
once.
Don't ever paint the neoprene or rubber part of a pipe collar
with paint, and don't caulk with petroleum based caulks -- both will result in
premature cracking, and leaks.
