One of the major steps to protect your roof from water damage, leaks, or ice dams is to install an ice and water shield. An ice and water shield is commonly known as a roofing underlayment and is a waterproof, rubberized underlay beneath the shingles. This underlayment acts as a barrier that protects certain areas on your roof and attic space from water damage and leaks. Thankfully, the installation process for the underpayment is not extremely complicated to do but needs precision and accuracy to complete.
How to Install
As previously stated, installing an ice and water shield is relatively simple; if you follow each step, you will not run into any problems.
- Prepare The Roof Deck – the first step is to prepare the area that will be covered and remove all debris.
- Measure And Cut – the next step is to measure the area and cut the ice and water shield to size. It is recommended to leave an extra six inches on each end for overhang.
- Installation – to install, start at the bottom of the roof. Please take off the backing of the shield and stick it to the roof decking. Overlap each row of ice and water shield by at least six inches.
- Install Shingles – after the shield is installed, you will have to reapply the shingles on it.
- Finalize The Installation – after putting the shingles back on, you may install the ridge cap.
