Michigan’s harsh winter conditions can be detrimental to roofs. The ice and water shield, although unseen, plays a pivotal role in safeguarding your roof from these extreme conditions. Here’s an in-depth look into the significance of this protective layer and why every homeowner in the Grand Rapids area should consider it.
The Hidden Protectors of Your Roof
Beneath the visible shingles of your roof lie several protective layers that shield your home from potential damage. One of these is the underlayment, which is fastened to the sheathing. This water-resistant barrier is essential for sealing around nail and staple holes, ensuring that water doesn’t seep into the sheathing.
However, the underlayment alone isn’t sufficient, especially for the lower edges of the roof that are prone to snow and ice accumulation. This is where the ice and water shield comes into play. Unlike the underlayment, this shield is completely waterproof and doesn’t have staples. Composed of polymers mixed with bitumen, it offers robust protection, especially for steep-slope roofs. Typically, two rows of this shield are applied along the bottom six feet of a roof, with additional layers placed in the valleys.
Varieties of Ice and Water Shield
There are three main types of ice and water shields:
- Sand-surface or granular: This type is slip-resistant, durable, and self-seals around roofing nails.
- Smooth surface: Slightly thicker than the sand-surface type, it’s suitable for both low-slope and steep-slope roofs.
- High temperature: Despite its name, this type is designed for roofs made of slate, tile, or metal, allowing them to expand and contract without sticking to the shield.
For homes in the Grand Rapids area, the first two types are commonly recommended. However, the choice of shield type is less crucial than ensuring its proper installation and adequate coverage.
The Role of Ice and Water Shield in Winter
During winter, the lower section of steep-slope roofs faces significant challenges. The freeze-and-thaw cycles can cause snow to melt near the roof’s surface, leading to water flowing beneath the snow layer. This water can freeze at the roof’s edge, especially if the gutters are clogged with snow and ice, resulting in ice dams.
When these ice dams melt, the trapped water can seep through the underlayment and sheathing, leading to potential damage in the attic, insulation, and even the living spaces below. This can further result in mold and mildew growth, necessitating emergency roof repair. The ice and water shield acts as a final barrier against this meltwater, ensuring that no water reaches the eaves, keeping your roof dry and safe.
Determining the Presence of an Ice and Water Shield
It’s challenging to ascertain the presence of an ice and water shield just by observing your roof from the ground. However, certain signs might indicate its absence:
- History of leaks, especially around the eaves.
- Increased energy bills during winter due to the HVAC system combating humidity and cold air from water infiltration.
- A professional inspection by a residential roofing contractor, like Guns N’ Hoses Roofing & Siding, can provide a definitive answer.
