As a roofing contractor, you're well aware of the devastating consequences of water damage, particularly during harsh winter conditions. You’ve surely had a recent project where a homeowner's attic suffered significant water damage due to a severe ice dam. Ice dams, in particular, often lead to leaks, mold growth, and structural damage. To mitigate these risks and protect your clients' homes, it's crucial to understand the importance of Ice and Water Shield (IWS) to prevent costly and time-consuming issues.
What is Ice and Water Shield?
IWS is a self-adhering, waterproof underlayment membrane that protects roofs from water infiltration, particularly in vulnerable areas such as eaves, valleys, and around penetrations. It acts as a barrier, sealing around nails to prevent water from seeping underneath the shingles.
Why is Ice and Water Shield Important?
- Ice Dam Prevention: Ice dams form when snow melts unevenly on your roof, causing water to back up under the shingles. IWS prevents this by creating a waterproof barrier that allows water to drain freely.
- Wind-Driven Rain: Strong winds can drive rain beneath shingles, especially at roof edges and valleys. IWS provides an additional layer of protection against this type of water intrusion. A good IWS can can prevent leaks even when strong wind speeds blow shingles off the roof.
- Leak Protection Around Penetrations: Any openings in your roof, such as chimneys, vents, or skylights, can be potential entry points for leaks. Since Ice and water barriers have modified bitumen adhesive back surface, it seals around those areas, reducing the risk of water infiltration.
Choosing the Right Ice and Water Shield: Prioritizing Protection and Proper Installation
Selecting the appropriate Ice and Water Shield (IWS) ensures optimal roof protection. Different roofing applications require specific types of IWS to deliver optimal performance. There are three main types to consider:
- Granular/Sand Surface IWS is ideal for valleys and areas with steep slopes. Its superior slip resistance prevents the material from sliding during installation, ensuring a secure and watertight seal. For example, a granular IWS might be used on a mountain cabin with a steeply pitched roof to provide extra protection in harsh weather conditions.
- Smooth Surface IWS is perfect for low-slope and flat roofs. Its smooth surface ensures seamless integration with other roofing materials, such as shingles or metal panels. For instance, a smooth-surface IWS might be used on a commercial building with a flat roof to prevent water infiltration during heavy rainfall.
- High-Heat IWS is specifically designed for metal roofs. It can withstand high temperatures and thermal expansion, protecting the roof from heat-related damage. A high-heat IWS might be used on a metal barn roof in a hot, arid climate to prevent premature aging and roofing material deterioration.
Choosing high-quality IWS from reputable brands and proper installation ensures optimal performance and longevity. Here are some key points to remember:
- Focus on eaves, valleys, and penetrations where water is most likely to accumulate.
- Follow the manufacturer's instructions, as different IWS products may have specific installation requirements.
- Ensure adequate attic ventilation to minimize ice dam formation.
Accurate Calculation for Optimal Protection
Calculating the right amount of IWS needed is crucial to ensure adequate coverage. Several factors influence this calculation:
- Roof Pitch: Steeper roofs generally require less IWS.
- Climate: Regions with harsh winters and heavy snowfall may necessitate more extensive coverage.
- Local Building Codes: Adhere to local building codes to determine specific requirements.
