This is the 8th installment of “Ten Things About Roofing You May Not Know!” which you can download as a free eBook.
The Peel and Stick roofing system has been around for many years and is one of the fastest growing types of roofing in the market today. There are some advantages and disadvantages to consider when evaluating a Peel and Stick roof.
Advantages of Peel and Stick Membranes:
- Installation is relatively easy for professionals so the labor costs will be lower in some cases.
- It can be a good choice for roof areas that are often difficult to waterproof.
- Peel and stick membranes don’t require fasteners, which eliminates the possibility of moisture intrusion thru fasteners.
- If severe weather damages your roofing system, the Peel and Stick will demonstrate its superiority, as it adheres to the roof deck better than other products. Your roof material (tile roofs, shingle roofs, etc.) may not be there, but the peel and stick will surely be left behind to protect your valuables!
The main disadvantage of a peel and stick membrane is that although it’s fully waterproof, this product will have the side effect of poor breathability. That means good ventilation is absolutely essential to prevent mildew and rot. PLEASE be aware as to whether your home/condo has or will have Isonene Closed Cell Insulation applied to the underside of the roof decking. If so, you do not want to install a peel and stick roofing system on the top side of your roof deck. This could cause the plywood to rot due to lack of air flow and poor breathability.
