In the context of roofing, “ice and water shield” is a self-adhering membrane designed to protect roof
structures from water infiltration caused by ice dams and wind-driven rain. In regions with cold climates, such as Massachusetts, ice and water shield is often recommended or required by building codes in
specific areas of the roof.
In Massachusetts, the use of ice and water shield is commonly required in roofing applications, especially
in areas prone to ice dam formation and heavy snowfall. Building codes and local regulations may specify
the locations where ice and water shield must be installed, typically along the eaves, in valleys, and
around roof penetrations such as chimneys, skylights, and vents.
The purpose of ice and water shield is to provide an additional layer of protection in vulnerable areas
where water is likely to collect or be driven under the roofing materials. This can help prevent water
infiltration and damage to the roof deck and interior of the building.
It’s important to note that building codes and requirements can vary by jurisdiction, so it’s essential to
consult the local building department or a qualified roofing professional like Millers Pro Roofing and
Siding, to determine the specific requirements for ice and water shield in a particular area of
Massachusetts. Additionally, following manufacturer’s guidelines and best practices for installation is
crucial to ensure the effectiveness of the ice and water shield in protecting the roof from water damage.
