Roofing Felt Vs Ice And Water Shield

It creates a waterproof barrier to standing water if installed correctly.

Roofing felt vs ice and water shield.

Install roof drip edge along the eaves add underlayment then place drip edge along the gable end. An ice and water shield is a totally impermeable membrane that prevents leakage through the roof in the event of an ice dam. I have used it for years. This grace ice and water shield self adhered roofing under layment covers 225 sq ft of roofing deck 36 in.

Ice and water protector membrane is a superior choice over roof felt for leak protection when properly installed and paired with the right products. If you see ice and water shield being installed you might think it is felt paper. Traditional felt paper does a very good job at stopping most leaks where water gets. It s an asphalt saturated paper that increases the water resistance of your roof from wind driven rains or blow offs.

The correct installation sequence for drip edge roofing felt and ice and water shield can be confusing since it changes from eaves to gable ends. Felt is much safer. I always install the felt above the ice and water barrier. The rubberized asphalt layer actually seals around roofing nails so they are totally water resistant.

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. The underlayment creates a secondary water barrier on the roof so leaks and water damage due to rain and storms are eliminated. Ice and water protector is part of a system working together to protect your roof including the shingles and other underlayments. Felt paper does not stick to anything.

Here s how to keep it straight. Once the high temperature ice and water shield has been laid down you can now add the second underlayment layer. Ice and water shield is different from felt paper because it s a rubberized membrane that sticks to itself and the wood roof sheathing. Roofing ice and water shield may look like traditional felt paper but it s vastly different in performance.

The ice and water barrier is much slipper than roofing felt. 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. Felt paper or tar paper is also a rolled material you see roofers nailing down under shingles. The best way is to.

I consider it to be the premium roofing water shield on the market especially for shallow pitched roofs that get a lot of snow and ice in the winter.
