A Roof Needs to Breathe – Proper Roofing Ventilation

Knowing Your Roof

Whether you are considering a new roof or have been living under the same one for a decade, understanding what goes into your roof is important. It does more than just keep off the rain, snow, and all the rest: it also regulates temperature, and protects the house from the nastier sides of the elements. There is a lot that goes into making a roof reliable, but fortunately, it all has a logic to it. While every part of the structure is important, there are a couple aspects that stand above the rest.

One such aspect of roof durability is ventilation. Just like any other part of your home, you want to make sure that nothing (aside from memorabilia) is building up in your attic. Everyone has seen what happens to a forgotten Tupperware of leftovers in the back of the fridge, no one wants the same thing to happen to their house. Therefore, proper insulation and airflow are key to making a roof effective at dealing with moisture and temperature. As an added bonus, the temperature-regulating properties of a well-made roof will also reduce energy consumption.

Alongside ventilation is a more visible aspect of the roof: the shingles. There are many options available, but the right material for you will depend on your location and personal taste. Although cedar shingles may accentuate the rest of the house perfectly, the climate of your area may be the deciding factor that turns you towards metal. Some types of shingling are more expensive than others, some are more heavy, but a good contractor will be able to help you narrow it down. If indecision is playing a role in getting your house reroofed, remember: asphalt shingles are just as good as anything else. There is a reason why they are the most popular type on the market.


Even the most enduring roof will break down eventually. After all, part of its job is to take a beating. A strong roof can typically be relied upon for around ten years, but as with anything else, it is good to check up on it regularly. Just because there are not any wet spots on the bedroom ceiling does not mean that something might be compromised. Fortunately, though, a damaged roof is easily noted. Shingles that are buckling, lacking the roughness lent by their built-in granules, or that are missing altogether are some common indications that a roof needs attention. Rotted or curling sections of roofing are also reliable signs. When in doubt, get a professional examination. It is better to be sure than to worry about a leaking roof every time rain rolls through.
