Snow brings dilemma for homeowners in an assortment of ways. And with the heavy snow loads and minus temperatures during the winter, many folks would be wondering whether or not their property (especially flat roofs) can endure the severe temperature change. To know does snow affect a flat roof just stick with this tutorial. Read on:
Pitched or Flat Roof
If you think that heavy snow excessively affects flat roofing structures, let’s tell you that this is nothing but just a misconception!
As a matter of fact, snow can question any roof type – no matter whether it’s pitched or flat – to extreme conditions which can cause damage or premature expiry. The roof’s ability to withhold the snow’s weight and remain intact during the winter season will entirely count on the quality of the products used and the workmanship.
Many colder countries with considerable annual snowfall carry on to employ flat roofing structures – the only difference is that they’re structured in a way to withstand any unfavorable weather conditions.
Traditional Flat Roofs
Conventional flat roofs are not able to perform so well in such low temperatures. Homeowners who’re facing issues with their flat roofs during winter season are required to replace their older-style felt roofs or ageing roofs.
After taking all things into consideration, you’ll probably be thinking that what makes the conventional flat roofs vulnerable to snow and ice damage? If yes, then walk through the answer below:
Contrasting to the pitched roof, a flat roof has no ability to depend on gravity to throw snow and ice away. Only one square foot of compacted snow can weigh up to 50 pounds. And increase in such a weight can prove severe on a flat roof, especially on older flat roofs that are generally seen on carports, sheds, and garages.
Massive snowfall that amasses on a typical flat roof can cause puncture wounds or even result in its collapse.
Melting and refreezing of the roof-top snow is another issue that is usually faced by many homeowners during winter. The melting and refreezing take place naturally by sun heat or though the warmth escaping from your home.
Once the snow melts, it frequently refreezes around the edges and other joins. The recurrence of the melting and refreezing process over a period of time can cause your roof to rapidly deteriorate.
Given that water seeps under the shingles it refreezes, so making an even bigger gap for future drainage can raise your shingles. As more melted water pours out, it can create cracks in the wood and walls, which will grow in size and eventually make water leak into your home.
It’s generally more cost effective if your flat roof is well past its sell-by date to opt for a contemporary, better-quality product.
On the other hand, a properly installed and designed flat roof made using up-to-the-minute technology will perform well in any climate. So, to install such type of flat roof in your home, it’s recommended to contact a trusted flatroof manufacturer.
