proper roofing ventilationIn some cities, summer comes as more of a curse than a blessing. With extremely hot temperatures and humidity levels on the rise, cozying up in your home feels like the best idea. But what if the roof of your house and consequently the interior of your house bake like an oven as well? That’s when proper roof ventilation comes to play. Roof ventilation that allows your house to have a breathing space prevent your roof from buckling under harsh weather conditions.

How can heat damage my roof?

We’ve heard how storm can cause trauma to the roof shingles and how moss can wreck the drainage but another criminal to roofing damage is heat. High temperatures can cause your roof to expand – simple science! But when the expansion happens in joints and beams, it can damage roof flashing and mess up with the roof’s drainage.

On the other hands, shingles can actually shrink and blister in the heat. These blisters can seriously affect the longevity of your roof.

Humidity and moisture are two other important causes of roof heat damage. Humid conditions favor moss and mold growth and we all know what happens from there. Mold and mildew can also make its way into the roof plywood sheathing deck. This can cause damage to the plywood by separating it from its roofing layers. If that happens, you might have to remove and replace both the plywood layer and the shingles layer on top.

Proper Roof Ventilation 

Proper roofing ventilation could be the solution to prevent any damage to your roof or entire home.

There are different kind of roof vents, all working to provide a better breathing space for your roof and thus, your home. Ridge vents, one of the most popular types, fits underneath the roof to prevent both overheating and excess moisture from building up.

Roof vents provide a proper exit of the heat waves through the attic. They prevent roof damage and aid in increasing the lifespan of your roof.
