Loveland Roofing: Article About Ice and Water Shield
There are many water-related problems that can affect a roofing system. Flowing water, falling rain and ice are just a few sources of potential water damage. Roofing contractors generally recommend an underlayment system to combat these issues. Using an ice and water shield product can effectively protect your roof against the elements and keep it in top condition. A reputable Loveland roofing contractor can evaluate your roof and see what type of protection it might need.
Ice and water shield products have been around since the 1980s and have swiftly become the top choice for preventing roof leaks in any type of climate. An ice and water shield resembles standard felt paper in some ways, but its performance is quite superior. Felt paper does an adequate job at stopping leaks by preventing water from coming into contact with the wood that resides beneath the roofing material. However, felt has its share of weaknesses. Nails used in securing the roofing materials can break through the felt paper and cause holes. Water can seep under the head of the nail and down its shaft where it ultimately gets through the hole in the felt. Once the water penetrates the felt, leaks can occur in the home.
Ice and water shields are composed of rubberized asphalt to prevent the problems associated with traditional felt. Each has a backing paper that peels away to reveal a self-adhering surface.

The shield is sticky enough to adhere effectively to both the wood sheathing as well as the layer below when the product is overlapped. Even if a nail penetrates an ice and water shield product, the rubberized material provides a seal similar to a gasket and prevents water from leaking down the shaft.
An ice and water shield can be applied to a variety of roofing materials. You can even apply the shield if you're re-roofing, although the product cannot be applied on old shingles. It's normally applied to the wood sheathing under the shingles. Not only are the main areas of the roof protected, but the regions around skylights, vents and chimney will also be kept safe. These trouble spots can be difficult to protect from leaks, but the shield can be curved around the corners to create a resilient barrier.
Applying an ice and water shield isn't an easy task; in warm weather, the product gets stickier than usual, and it can be difficult to align it properly without wrinkles. The average homeowner usually faces a significant learning curve when first dealing with this material. Working on a steep roof is also a dangerous situation, especially if it's slippery or frosty. It's always safest to have a professional roofing contractor install the ice and water shield on your roof.
