Attic ventilation helps eliminate excess heat and moisture from your roof that can lead to several issues in your home. That said, your roof can last longer if your attic has sufficient ventilation. Ensuring good airflow in this part of your home will also help you save on energy bills.
A local roofing and siding contractor shares problems that poor attic ventilation can cause.
Sagging Roof Decking
When moisture doesn’t have a way out in your attic, it can penetrate and accumulate in the decking. Over time, the adhesives holding the decking together may dissolve. As a result, the decking will start warping and sagging.
Reduced Roof Life Span
The heat from a poorly ventilated attic can speed up the deterioration of shingles and the rest of your roofing system. You will know you need to improve your attic ventilation if there are cracked shingles and excessive granule loss. If you see these signs, be sure to contact a professional. Whether you need roof repairs or are planning a window replacement, Shine Construction Inc. is here to help.
HVAC Malfunctions or Failure
Your heating and cooling system will also suffer if your attic doesn’t have sufficient ventilation. The heat from your attic can radiate into your living space, causing your HVAC system to work harder than it should. The added load can put a strain on your equipment, shortening its service life and causing your energy bills to increase.
Ice Dams
Uneven roof temperatures and poor attic ventilation can result in the formation of ice dams. These ice formations keep snowmelt from draining off the roof properly. The warm air trapped in the roof deck causes snow to melt. After ice dams form, water will back up, eventually causing leaks.
