What Is Peel And Stick Roofing Underlayment?
Peel and stick underlayment is made from a mixture of high-density polyethylene or polyester, which are rubberized polymer blends. The elasticity in this material makes it more durable than traditional felt as well as tear-resistant.
As an additional layer of waterproofing protection, this self-adhesive underlayment helps prevent damage and leaks caused by wind-driven rain and ice dams. It has a longer life span compared to the felt underlayment, so it prolongs your roof’s expectancy.
Since this underlayment doesn’t wrinkle, it creates a watertight barrier that blocks any space for water to pool and potentially penetrate its barrier. Another advantage is that this underlayment is easier to install and doesn’t require any nailing.
The best choice for flat and low slope roofs is the modified bitumen peel and stick roll roofing systems since this type of membrane roofing improves built-up roof systems.
It is also easier to install because the reinforcing fabric and bitumen binder are already combined into a single roll. These polymer-modified bitumen roof materials are stronger, more flexible, or more heat resistant.
In order to ensure that this modified bitumen adhesive roll is watertight, it is usually installed in two or three multiple layers. and are perfect for low-pitched roofs where shingles, slate, or tiled roofing would not work as well.
How Long Does This Roofing Last?
When it comes to peel and stick roofing, one common question is how long it lasts. This roofing underlayment is typically rated to last longer, especially since it is an underlayment that goes below other materials.
Generally, peel-and-stick underlayment can last 15 to 30 years, depending on the quality of the installation and materials used.
It comes with at least a 15-year limited warranty up to a 40-year limited warranty for some brands, making it more than twice the lifespan of traditional roofing felt. Another added benefit is the underlayment’s tear strength.
This type of underlayment has a much higher tear strength than traditional asphalt, which makes it less likely to rip in high winds. And because it has reduced water permeability, which prevents rain from leaking to the roof’s deck.
