Ice and Water Shield. What is it good for?


While it is natural to focus first on the visible portions of the roof — which is the roofing shingles or alternative material — it is often what lies underneath that is actually more important in terms of protecting the home. Especially in Colorado, and states where more than 12 inches of snow can fall at a time, and temperatures can remain low enough for ice to build on eaves and edges of the roof, insuring a waterproof barrier becomes pivotal, and something that ASAP ROOFING always advises.


According to Research Roofing, a national website designed to inform and educate consumers about roofing, “Roofing Ice and Water shield is a critical component to any new roofing system especially in cold weather climates. Many local building codes require Ice and Water shield and National Building CODE states Ice and water shield must start at the roofs eave edge and extend 2 ft inside heated wall space of a structure.” The website further advises that, “Essentially all the weakest or most prone to leaking areas of a roof should be coated with Ice and Water Shield before installing shingles or any other roofing products.”



There are four major benefits to ice and water shield protection on a roof:




  • Protecting your home structure: By protecting your home structure with ice and water shield the risk of any depreciation due to water damage is mitigated.


  • Avoiding repairs later: Preventing water damage is always a good idea, especially when it comes to roofs, and failure to do so can lead to costly repairs including replacing wood structures, removing mold, and repainting.


  • Creating watertight seal: Ice and water shield underlayment is designed to ensure that there is no water leakage which could lead to mold development, wood decay, and deterioration of existing structures.


  • Improved appearance: Because Ice and water shield barriers lay flatter under roofing shingles, the overall roof appearance is improved.



Because it is the aim of ASAP ROOFING to always inform customers about the best ways to protect their home and ensure no loss due to water damage, the specialists there typically recommend ice and water shield protection for homes.

    Great article! In the Southeast we are seeing heavier snows. With our temperatures changing so rapidly (we went from 60 degrees to a foot of snow the same week) the moisture expansion and subsequent contraction can place stress on the elements of our roof - making even a small opening more prominent.

      Often times, home owners under estimate how damaging the snow load can be.

    It's important to not cover the whole roof surface with ice and water shield. Why? Because a roof must be able to breathe.
