Does My Roof Need Ice and Water Shield?
In the northern United States, many homeowners will install ice and water shield, a self-adhering membrane that protects vulnerable roof areas from ice dams and wind-driven rain. However, if you’re new to the area, you may be asking yourself, “Do I really need this stuff?.” The answer, in most cases, is yes. Here’s why.
Ice dams form when snow on a roof melts and refreezes at the eaves, creating a dam that can back up water under the shingles and into the attic. This can cause serious damage to the roof, the attic, and even the interior of the home. Ice and water shield helps to prevent ice dams by creating a barrier between the shingles and the roof deck. The water-resistant membrane allows water to drain off the roof, preventing it from freezing and forming an ice dam.
How Much Ice and Water Shield Do I Need?
The amount of ice and water shield you need will depend on the size of your roof and the slope of your roof. A general rule of thumb is to install ice and water shield on the eaves and valleys of your roof, as well as any other areas that are likely to accumulate snow and ice. You should also install ice and water shield around any roof penetrations, such as chimneys and skylights.
If you’re not sure how much ice and water shield you need, it’s always best to err on the side of caution and install more rather than less. Ice and water shield is relatively inexpensive, and it can save you a lot of money in the long run by preventing damage to your roof and your home.
The Benefits of Ice and Water Shield
In addition to preventing ice dams, ice and water shield offers a number of other benefits, including:
- Wind Resistance: Ice and water shield can help to protect your roof from wind damage. The membrane’s strong adhesive bond to the roof deck prevents the shingles from being blown off in high winds.
- Water Resistance: Ice and water shield is waterproof, which means it can help to protect your roof from rain and snow. The membrane’s water-resistant properties help to keep water out of the attic and the interior of the home.
- Durability: Ice and water shield is a durable product that can last for many years. The membrane is resistant to UV rays and other environmental factors, which means it will not deteriorate over time.
Tips for Installing Ice and Water Shield
If you’re installing ice and water shield yourself, there are a few things you need to keep in mind:
- Make sure the roof deck is clean and dry before installing the ice and water shield. Any dirt or debris on the roof deck can prevent the membrane from adhering properly.
- Apply the ice and water shield in overlapping strips, starting at the eaves and working your way up the roof. Overlap the strips by at least 6 inches to ensure a watertight seal.
- Roll the ice and water shield firmly into place using a hand roller. This will help to ensure that the membrane is properly adhered to the roof deck.
- Install flashing around any roof penetrations, such as chimneys and skylights. Flashing will help to prevent water from leaking into the attic through these openings.
