As of my last knowledge update in September 2021, Massachusetts building codes, specifically the Massachusetts State Building Code (780 CMR), require the installation of ice and water barriers (often referred to as ice and water shield) in specific areas of the roof. These requirements are intended to address the potential for ice dam formation and water infiltration in regions subject to cold weather and
snowfall, such as Massachusetts.
The building code typically mandates the use of ice and water barriers along the eaves of the roof and in
other vulnerable areas, such as roof valleys, around roof penetrations, and in certain roof pitches and
slopes. The specific requirements for the installation of ice and water barriers are outlined within the
building code and may vary based on factors such as local climate conditions and roof design.
It’s important to note that building codes are subject to updates and revisions, and local jurisdictions
within Massachusetts may also have additional requirements or amendments to the state building code.
Therefore, it’s crucial for homeowners, contractors, and builders to consult the most current version of the
Massachusetts State Building Code and any local building regulations or amendments to ensure
compliance with the specific requirements for ice and water barriers in roofing installations.
For the most accurate and up-to-date information regarding the Massachusetts ice and water barrier
requirements for new roof installations, individuals should refer to the Massachusetts State Building Code
and consult with local building officials or a qualified roofing professional like Millers Pro Roofing and
