Preserving heat, insulation, and roof integrity through proper attic care.
Did you know that a clean attic can improve your home’s energy efficiency?Damp, chilly winters in the Portland and Vancouver areas can threaten the integrity of roofs. Fortunately, proper attic care can provide protection for rafters and shingles while improving the efficiency of your home.
Empty Attic, Better Insulation
Attic insulation provides protection for the underside of your roof. However, if your attic is stuffed full of stuff, it’s hard to install or replace insulation anywhere in that space. Attics that are used primarily for storage are often neglected, leading to stagnant air that can result in damage when it comes in contact with heat or moisture from the rest of the house.
Installing or upgrading attic vents may seem like the opposite of insulating, but proper air flow is essential to a healthy roof. Vented attics stay cool in the summer so the undersides of roof shingles don’t overheat and dry out. In the winter, ventilation prevents the buildup of mold-causing moisture that can lead to the rotting of roof components. When heat rises from the rest of the house, ventilation keeps condensation from turning into frost and prevents unwanted cycles of freezing and thawing.
Poor insulation in the attic can lead to air and water leaks. An air leak not controlled by ventilation leads to a transfer of air from the attic to the outside and vice versa. This makes the attic colder in the winter and hotter in the summer, creating temperature fluctuations that can lead to internal roof damage.
Water leaks soak insulation, destroying its ability to resist heat radiating up from the rest of the house. Wet insulation lets in ambient heat as well as moisture which makes the attic environment not only inefficient but also unfriendly to your roof. As with poor ventilation, wet insulation can lead to mold growth which wears away at the rafters and may cause even more leaks. Plus, if you do store anything in the attic, leaks and changes in temperature will damage your belongings. Together, damage from poor insulation and leaks can lead to loss of property and high roof repair bills.
