If you see ice and water shield being installed you might think it is felt paper.
Roofing felt vs ice and water shield.
Roofing ice and water shield may look like traditional felt paper but it s vastly different in performance.
Such as 1 ply of peel an stick.
Ice and water protector is part of a system working together to protect your roof including the shingles and other underlayments.
Depending on the slope of the roof this product could be installed to cover the bottom 6 feet of the roof or with a very low slope cover the entire roof.
What does felt paper do.
They are also slip resistant which protects our team.
Ice and water shield is a far superior product compared to basic roofing felt paper.
The balance of the roof area is covered with synthetic underlayment that will not wrinkle when exposed to the sun.
Ice and water protector membrane is a superior choice over roof felt for leak protection when properly installed and paired with the right products.
Felt is much safer.
Roofing ice and water shield may look like traditional felt paper but it s vastly different in performance.
They can be installed over low slope roofing and are installed in plies.
If the roof slope is below 3 12 pitch see our previous post on how to determine a roof s pitch the entire roof should be covered but only if the roof is conventionally vented cold roof construction.
Ice and water shield is also installed under shingle roofing when the slope of the roof is 3 in 12 and less.
Felt paper or tar paper is also a rolled material you see roofers nailing down under shingles.
An ice and water shield is a totally impermeable membrane that prevents leakage through the roof in the event of an ice dam.
Gcp invented fully adhered roofing underlayments more than 35 years ago.
The ice and water barrier is much slipper than roofing felt.
Grace ice and water shield fully adhered smooth surface roofing underlayment provides best in class roof leak protection against wind driven rain and ice dams.
Once the high temperature ice and water shield has been laid down you can now add the second underlayment layer.
The grace ice water shield 36 x 36 roll is another product that is recommend in areas that get more rain and snow.
Traditional felt paper does a very good job at stopping most leaks where water gets.
The underlayment creates a secondary water barrier on the roof so leaks and water damage due to rain and storms are eliminated.
It can be very dangerous when the new roofer is tearing off the old shingles and looses his or her footing on the ice and water barrier.
It s an asphalt saturated paper that increases the water resistance of your roof from wind driven rains or blow offs.
