One of the most common roofing problems our roofing company in Pittsburgh, PA, deals with typically stems from poor attic ventilation. It is vital for your roofing contractors in Pittsburgh to properly install attic ventilation to address two important factors involved in home comfort: heat and moisture. Moisture from everyday activities such as cooking, dishwashing, and showering will concentrate in your attic without a means of escaping through attic ventilation. When unaddressed, trapped heat, and moisture results in many problems.
- Shortened roof life. Excessive heat and moisture literally bake the underside of your roof, greatly shortening the life of underlayment and shingles. Cracked shingles and premature granule loss can be signs of improper roof ventilation.
- Decay of framing and decking. Continual moisture in an attic allows dry rot, which weakens the structural components of the roof and decreases roof value.
- Mold and mildew. Unhealthy mold flourishes in humid environments, triggering respiratory and other health problems for occupants and potentially damaging items stored in the attic.
- Damp insulation. When humidity levels are very high in an attic, condensation can form on the roof deck and drip down onto insulation. In the winter, you may even observe frost. Insulation that absorbs moisture can’t insulate as well.
- Air conditioner replacement. With excess heat building in the attic, an air conditioner will struggle to keep the air inside the home cool. This heavy load can wear on the unit and run up cooling bills.
- Ice damming. When warm air rises to the roof deck of a poorly insulated attic in winter, it melts snow on the roof. The snowmelt refreezes as it runs down to the cold lower portion of the roof, creating an icy barrier or “dam.” Subsequent snowmelt then backs up behind the dam, resulting in leaks.
Over time, the issues stemming from improper attic insulation result in a damaged roof, higher utility bills and a potentially unhealthy living environment.
