If you're having issues with ice build-up and you notice little or inconsistent insulation in your attic, then taking the necessary steps to insulate and seal air leaks should be your top priority. Aerosol foam insulation is a great option for preventing ice build-up in an unventilated attic, but it's important to note that this is not a DIY project and should only be done by a licensed professional. Additionally, wrapping any heat sources in fiberglass insulation can help reduce thermal transfer of heat to the attic space. Sealing the air channels in the living space located under the attic is also essential.
Replacing old light fixtures with modern recessed lights that can be fully insulated will help reduce the amount of heat radiated to the attic. It's important to make sure that the roof insulation is properly installed where the roof meets the wall. If space is limited, it's easy to not install enough insulation in these areas. It's also important to note that a cold attic actually means that there are no ice accumulators, while a warm attic means that extra caution must be taken. Overall, as an expert in SEO, I recommend insulating and sealing your attic as a key step to preventing ice build-up on your roof.
