Most homeowners picture the shingles they see from the street when they think of a roof. A roof, however, is much more than that.
Your roof is made up of a variety of components and materials that work together to create a full roof system. Ice and water shields are one of these essential roofing components.
Every homeowner should be aware of the components that go into the construction of their roof. We’ll discuss the information you need to know about ice and water shields in the following article.
You’ll understand what ice and water shields are by the time you’ve finished reading this, along with three important points.
Ice And Water Shield: What Is It?
Your roof is protected from ice and water damage by a waterproof coating commonly known as an Ice and Water Shield. When water leaks through your roofing material, its main purpose is to protect your roof decking (metal roof, asphalt shingles, etc.).
Ice and water shields must be built on/around specific parts of your roof, such as the valleys, the region surrounding penetrations, and the roofs with a two-twelve, three-twelve, and four-twelve pitch. Every roof needs to have it because of how important it is.
There is also a code for people who live in the US above the snow line. In order to prevent leaks brought on by ice damming after a heavy snowfall or ice storm, this regulation requires the installation of ice and water shields along the margins of your roof, (check here for more info).
If you reside in a region that has significant snowfall, municipal regulations generally require you to install two rows of ice and water shield along the rakes and eaves of your roof.
Understanding The Ice And Water Shield: 3 Things
You are now aware of what ice and water shield is and why your roof needs it. You still need to understand more about it, though. The three things you should know about ice and water shields are as follows.
The Three Varieties Of Water And Ice Shield
There are three different types of ice and water shields: smooth, high heat, and granular/sand surface.
The thinnest of the three varieties is used in roof valleys and is composed of granules or sand. It serves the same purpose and accomplishes the job well despite not being as thick.
Low slope roofs employ ice and water shields with a smooth surface. When a roof has a 2/12, 3/12, or 4/12 pitch, as described in the first section, this style is appropriate.
Protection is important against ice and water on a low-slope roof. High heat ice and water barriers, which are typically used on metal roofs, are constructed of cotton-like fibers. It won’t stick to metal during its expansion and contraction because of the material it is made of.
