From the Danforth to Etobicoke, from King St. to Sheppard Ave., flat roofs can be seen in just about every neighbourhood in Toronto. A mark of our city’s most historic buildings and an added subtle touch to some of the city’s most unique modern homes, flat roofs contribute to Toronto’s distinct urban aesthetic. Homeowners in our city have made the best of their flat roofs: taking advantage of their affordability, installing solar panels to generate green energy, and using them as creative recreational spaces such as rooftop decks and gardens. But now that the season for decks and gardens is well over, it is important that homeowners the time to consult Toronto roofing experts, in order to prepare their flat roofs for the coming winter. Harsh winter conditions can exacerbate any existing issues, so the fall is a great time to prevent such common problems as:
Ponding – the pooling of water on flat roofs after heavy rain or snowfall. This is not an issue inherent to flat roof homes, since even flat roofs are built to maintain a degree of slope in order to facilitate water drainage. Ponding water is usually a sign of poor drainage, which should be addressed in order to avoid the premature deterioration of your flat roof. Persistent ponding is most detrimental during the winter months, as ponding water can become trapped in a thaw-freeze cycle on and below the surface of your roof.
Damage Due to a Thaw-Freeze Cycle – a particular hazard of ponding during the winter months. If ponding water solidifies into ice before it can effectively drain off the roof, it may be trapped in a thaw-freeze cycle, gradually penetrating below the surface of your roof. If seeps into cracks and crevices of your roof, the next drop in temperature will cause it to expand as it freezes, creating a wider channel for further seepage and water buildup. This cycle of deterioration can last the entire winter season, resulting in serious damage to your roof. In order to prevent this before it occurs, it is advisable that homeowners seek flat roof repair help in Toronto before winter is properly here.
Leaks – the initial stages of leaks are difficult to detect. Unfortunately, once a leak has become obvious, significant damage to your roof, ceiling and walls has already been done. Even minor leaks can lead to costly repairs if not addressed early. Which is why it is important to hire a professional to inspect for early signs of leaking in your roof. By the winter arrives, the heavy snow and ice buildup can aggravate the leak, resulting in costly issues, such as internal water damage and even the bowing or caving of your roof.
In order to avoid these issues, it is advisable that homeowners in Toronto contact their local expects in flat roof repairs before winter arrives. Given proper maintenance, your flat roof will brave the cold months and keep you safe from the elements for seasons to come.
