Pipe Collar Repair

• 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.
