Attic insulation is one of the most vital components of your roofing system. Despite its importance, some myths about it continue to persist. In today’s blog, local residential and commercial roofing contractor Meredith Home Improvements reveals the truth behind the most common misconceptions about attic insulation.

Myth: Spray Foam Is Harmful

This notion stems from the fact that spray foam insulation once contained urea-formaldehyde and is generally found in homes built before the 1970s. At the time, authorities were not yet aware of the dangers of the chemical compound, which is emitted by the foam insulation through a process called off-gassing. Fortunately, today’s foam insulation no longer poses health risks and has been marked as safe for use in residential applications.

Myth: Insulation Is Only Needed for the Colder Months

Attic insulation does help retain indoor heat during the colder months and reduce the need for indoor heating. However, residential roofers note that it also slows down radiant heat, keeping the indoors cool during the hot summer months. In addition to reducing heating costs, a properly-insulated attic can also prevent the formation of ice dams on the roof during the cold months.

Myth: Vapor Barriers Trap Moisture

A vapor barrier is a type of plastic sheeting that protects the insulation from coming into contact with moisture. However, it is not like your ordinary plastic sheeting; it allows moisture to evaporate. Apart from protecting insulation against damage, applying vapor barriers also helps prevent the spread of mold and mildew and lessen the chances of rot from occurring on the roof’s supporting structure.
