The Importance of Proper Roof Ventilation

Roof ventilation is incredibly important to your home’s energy efficiency and comfort. If your roof is not properly ventilated, then you can expect all sorts of problems on the outside and inside of your house. In this blog post, DryTech Roofing, one of the leading roofing contractors in our local area, explains everything you need to know about roofing ventilation.

Why Is Roof Ventilation Important?

Roof ventilation is important because it prevents excess heat and moisture buildup in your attic. Warm air rises. Without ventilation, this warm air ends up trapped in your attic, overheating the roof decking and the ceilings in your home. The exterior roofing materials and shingles on your roof also age more quickly because of prolonged heat exposure. Roof ventilation also prevents condensation buildup in the attic during winter. It also helps prevent ice dam formation.

What Are the Signs of Poor Roof Ventilation?

As one of the most experienced roofing contractors in our area, we look for these signs when checking if an attic is properly ventilated.


  • Damp Insulation – When insulation gets wet, it compresses and it ceases to do its job properly. Wet insulation is often a sign of condensation in your attic,


    • Water Stains Water has absolutely no business being in your attic. If you spot any signs of water damage in your attic, then there’s a good chance that there’s a problem with your insulation.


  • Frost on Wooden Beams and Rafters – This is a clear sign that there is moist air that’s trapped in your attic. Proper ventilation should fix this problem.
  • Ice Dams – Ice dams form because of a combination of inadequate roof ventilation and attic insulation. Your home’s warmth ends up transferring to the roof, where it melts snow. This melted snow ends up refreezing into an ice dam.


If you spot any of these signs, then call us for a roof inspection.
