Why Building Codes Are Requiring Ice and Water Shield on Homes
Building codes are constantly evolving to keep up with new technologies and address changing weather patterns. One recent change that has been gaining traction is the requirement for ice and water shield on homes in certain areas.
What is Ice and Water Shield?
Ice and water shield is a self-adhering membrane that is installed on the roof deck under the shingles. It helps to prevent water from seeping under the shingles and into the roof deck, which can lead to damage and mold growth.
Why is Ice and Water Shield Important?
There are a few reasons why ice and water shield is becoming increasingly important:
- Climate change: Climate change is leading to more frequent and severe weather events, including increased snowfall and ice dams. Ice dams can cause water to back up under the shingles and into the roof deck, leading to leaks and damage.
- Improved building materials: Modern roofing materials, such as asphalt shingles, are less durable than older materials and are more susceptible to damage from water. Ice and water shield can help to protect these materials from water damage.
- Mold growth: Mold can grow in damp environments, and a leaky roof can provide the perfect breeding ground for mold. Ice and water shield can help to prevent mold growth by keeping the roof deck dry.
Where is Ice and Water Shield Required?
The specific requirements for ice and water shield vary by location. In the United States, the International Residential Code (IRC) recommends the use of ice and water shield in areas where there is a history of ice forming along the eaves. However, many local building codes adopt the IRC and add their own amendments. These amendments can make ice and water shield mandatory in certain areas, even if it is not required by the IRC itself.
For example, in Michigan, the state building code requires ice and water shield to be installed at least 6 feet from the eaves or edge of the roof, and 3 feet from any inner walls. In Florida, the building code only requires ice and water shield to be installed around roof penetrations like skylights and chimneys.
How Has the Building Code Changed Since 2018?
The requirements for ice and water shield have been gradually increasing in recent years. In 2018, the IRC made some changes to its recommendations for ice and water shield. These changes included:
- Requiring ice and water shield to be installed in all valleys, regardless of the slope of the roof.
- Requiring ice and water shield to be installed up to 6 feet from the eaves in areas with a slope of less than 4:12.
These changes reflect the growing awareness of the importance of ice and water shield in protecting homes from damage.
What are the Benefits of Using Ice and Water Shield?
There are a number of benefits to using ice and water shield, including:
- Reduced risk of leaks: Ice and water shield can help to prevent leaks by sealing the roof deck and preventing water from seeping under the shingles.
Improved roof performance: Ice and water shield can help to extend the life of your roof by protecting it from water damage.
- Reduced risk of mold growth: Ice and water shield can help to prevent mold growth by keeping the roof deck dry.
- Peace of mind: Knowing that your roof is protected from ice and water damage can give you peace of mind.
If you are considering having a new roof installed or if you are concerned about the condition of your existing roof, I recommend talking to a qualified roofing contractor about whether ice and water shield is right for you.
