Installing Ice and Water Shield
Thank you for visiting the Installing ice and water shield page.Ice and water shield also known as ice and water granulate goes on before all other materials and provides great protection against the elements and water damage. It is often your only protection against ice dams.
Ice dams are where the ice builds up and freezes pushing water underneath of shingles causing leaks. The most common area for ice dams are in areas with a low pitch and by the eaves. That is why it is recommended you use ice and water on any roof with a pitch of less than 4/12. We recommend placing it in all valleys and on all eaves. Ice and water comes in rolls of 66 linear foot.
Installing ice and water shield can be done fairly easy depending on the roof it will require a little hard work and you will want a second set of hands.
Things you will need or want to have
• Ice and Water shield
• Razor blade
• Tap measure
• Galvanized roofing nails
• Optional tools pneumatic roof nailer
• Air compressor, air hose
The first step is to installing ice and water shield is to calculate your roofs square footage if you have not done this please visit our roofing calculator page. Once you have calculated your square footage and purchased your materials we can now begin. Try to avoid walking on the ice and water shield the granulate wears off and can be very slippery.
You will start at yours roofs eave at one edge and work your way across securing the granulate material as you move along try placing as few nails as possible on a warm day the material should adhere well. The ice and water shield has an adhesive on the back side to make sure your sheeting is free of debris. Run the bottom of ice and water even with the bottom edge of your roof and only roll as much as you can handle keep in my mind the adhesive gets a bit tricky.
A very important note is that you will want to do your best to keep the roll straight and prevent bubbles. When installing the ice and water in the valley remember not to put any nails within 10 inches of the valley keep them on the outside.
Additional notes and safety warnings
• If you have any valleys simply run the material using the valley as your center line to split it equally.
• When you come to a point where you run out of ice and water simply over lap the paper from the new roll by about 12 inches.
• When cutting into a new roll of granulate be careful to unroll it a bit so you do not cut into other layers.
• Installing granulate can be dangerous you may want to install toe boards for safety.
• Be careful where you ice and water can rip
• Never walk on wet granulate even if it is only morning dew it can be very slippery
• Consider using toe boards
