Madison Roofing: Article About Ice and Water Barriers
To protect the home's roof from moisture damage, roofers combat the effects of water infiltration by adding one layer of underlayment under the shingles. Today, roofing felt remains the most popular underlayment product on the market, but contractors often suggest ice and water barriers as a secondary layer. In fact, Madison roofing professionals can add these barriers to almost any home during a roof replacement project. Regardless of local weather patterns, rooftops benefit from extra underlayment layers by dramatically increasing their material lifespans.
Homeowners have two main installation styles to choose from when considering an ice and water barrier. Some residents simply want roof edges to be protected with barriers, so they select a partial installation. Contractors line roof edges with barrier material, which is a similar procedure to the addition of drip edges. Alternatively, contractors can lay a barrier across the entire rooftop during a major renovation. This installation choice protects all wood decking locations from possible moisture penetration throughout the year.
Roofers must remove all surface materials from decking to start a barrier installation. With the wood decking exposed, contractors also pull all fasteners from the surface. Proper barrier installation requires a smooth surface, so no roofing nails can remain in the wood. Reputable roofers pull nails and fill the open holes with roofing cement for a quality barrier installation. Any holes or crevices leading into the home are vulnerable to leaks, even with a strong barrier installed above them.

Ice and water barriers differ from traditional roofing felt because they have adhesive built into one side. Contractors roll barriers out across roof surfaces with the sticky surface facing down. Barriers almost immediately adhere to wood decking, so installation expertise is crucial to prevent unsightly material wrinkles. In fact, contractors even overlap barrier edges for added moisture leak protection, so installation techniques must be sound for quality results.
While the roofing felt and shingles do a good job of creating a seamless layer on the roof, homeowners might be concerned about fasteners piercing their new installation. Contractors drive roofing nails through all material layers to connect them safely with the lower wood decking. As nails pierce barriers, however, the rubber materials actually form a water resistant connection with fasteners. Only poorly installed nails, such as underdriven fasteners, have the potential for leaking through the years.
Ideally, quality roofers must complete barrier installations because these materials can be difficult to manage by inexperienced people. Tacky barrier sides stick to nearly any surface without proper material management, so this challenge makes the barrier vulnerable to wrinkles. Any folds within the material will telegraph to shingles above and compromise the entire roofing system. In the end, hiring experienced professionals contributes to a long lasting installation.
