Michigan roofing maintenance and repair costs can add up quickly – especially with weather like Michigan’s. Adding a roof underlayment known as an ice and water shield when replacing your roof in Michigan can save you time and money. We recommend all homeowners installing ice and water shield on their new Michigan roof replacement, learn more about what to look for when replacing your Michigan roof:
Michigan Ice and Water Shield Basics
An ice and water shield – or “protector” – is a self-adhesive roof underlayment that blocks water from entering the structure when ice dams form or from wind-driven rain. Made of slip-resistant, modified bitumen, the ice and water shield provides a watertight barrier around the roof, reducing exposure to water.
Ice and Water Shield Installation
We recommend Michigan homeowners invest in a quality ice and water shield because of increased risk of Michigan roof damage due to ice dams and wind-driven wind. Since eves and roof edges are especially vulnerable to ice and water, shields should be installed around these areas. Additionally, it’s always a good idea to install an ice and water shield around chimneys, vents, skylights, and flashings.
Typically, protectors come in sizes that are 3-feet wide, which is a good standard for installation. However, lower roof slopes may require installing the shield higher. Check with your local roofing professionals to make sure you are installing the right amount of shield, dependent on expected ice dam formation for your home.
Installation Best Practices
When installing an ice and water shield on your Michigan roof, it’s important to know the insulation basics and best practices, so the shield can protect your home from ice and water. Follow these guidelines to ensure proper installation:
- All ice and water protectors should be installed before installation of the roof felt and underlayment. When installing near chimneys and dormers along metal roofs, double check the protector is under the flashing.
- Before installing a drip edge, make sure the ice and water protector adheres to the roof deck and eves. This will ensure a proper watertight seal around your home’s roof.
- Typically, it’s not recommended to apply a protector over your entire roof. As this can be expensive and not necessary, apply a protector to the most vulnerable areas – such as eves, chimneys, vents, skylights, and flashings.
- Install ice and water shield barriers that are at least 3-feet wide from the edge of your roof. If you have a lower roof slope, consider using 6-feet as the rule of thumb.
- Never install ice and water shield over existing shingles. When replacing your Michigan roof, make sure the shield is applied underneath the shingles and felt paper.
