Avoid These Errors with Tips from Local Roofing Companies
If you have an attic in your home, then there’s a good chance that ventilation plays a key part in maintaining that attic space. Along with proper insulation and roofing materials, ventilation is a piece to a larger puzzle of roof care. But roofers in Ottawa are noticing a lot of confusion about exactly the role that ventilation plays, how much is enough, and what it can and can’t fix. Here are some of the biggest mistakes being noticed.
Not enough – or too much
Many people assume that there is a single, golden number for how much ventilation is needed in their attic. When you ask experts in roofing in Richmond or Ottawa, they’ll set the record straight on this one. Every attic needs different things, depending largely on its size, the types of vents being used, and climate. So you want to hire expert Ottawa roofers to figure out exactly how much the right amount is. Too little, and you’ll get moisture buildup in the winter, and poor energy efficiency in the summer. Too much, however, and you begin to invite leaks and other damaging intruders. Being precise will go a long way toward preserving the quality of your attic.
Thinking vents aren’t important in winter
It’s easy to see why some people would question the effectiveness of having an opening in the roof during the winter – you want to keep the warm air inside your house, after all. However, you actually don’t want to let your attic get too warm in the winter. The main reason for this is that it can create ice dams, which can then cause severe water damage to your roof. How this happens is, heat trapped in your attic will rise to the top, warming and even melting snow on the outside. This melt will slide downwards, eventually refreezing in the eaves, creating a dam that prevents drainage. While proper ventilation is not the only factor in preventing an ice dam, Richmond roofing companies recommend making sure the attic is properly ventilated all year round to help prevent this potentially disastrous phenomenon.
The issue with many DIY roofing projects is that you don’t get the experience and knowledge of a seasoned Ottawa roofer. One problem that comes up often is a crooked turbine exhaust. The trick to a turbine exhaust is that it needs to be completely, 100% level when installed; if it’s not, it won’t turn, and it won’t work properly. Another common mistake is not installing enough intake. Ideally, you want a pretty even split of intake-to-exhaust. This sometimes happens because a house has no soffits, in which case alternative intake methods are very important. To get the best results, contact your local Ottawa and Richmond roofing experts with any questions you have.
