Adequate insulation and an efficient ventilation system in your attic are key to the health of your roof. Without proper attic insulation or ventilation, your roof will suffer and you’ll face a host of problems.
Here’s how proper insulation and ventilation help keep your roof in good shape:
Preserving Wood Decking’s Structural Integrity
Poor attic insulation and ventilation can lead to condensation in the attic. Chronic condensation will weaken roof decking slowly but surely, undermining the overall health of your roofing system. In time, it will lose its strength. Even if your asphalt shingles are fairly new, you might have to replace them if your roof decking fails.
Preventing Shingle Deformation
Your residential or commercial roofing shingles will curl when there’s excessive heat beneath them. High attic temperature accelerates wear and tear, causing shingles to lose their protective seal. A large portion of curled shingles doesn’t only decrease curb appeal, but also provides entry points for water to come inside.
Inhibiting Ice Dam Formation
An overly hot attic makes the majority of your roof warmer than the eaves. The difference in temperature causes the snow that lands on your roof to melt, only to refreeze once it drips down to the edge of your roof, forming ridges of ice. These are called ice dams, and they set the stage for water seepage and put tremendous stress on your roof’s foundation. Apart from keeping your gutters clean, having proper attic insulation and ventilation reduces the chances of ice damming and minimizes the need for roof repair.
