There are many different roofing materials that you can use for your house rooftops. It doesn’t really matter whether you own a commercial building or just a regular home where you go to every evening from work. You can put a flat roof for your home or commercial building provided you have the necessary materials for it. When it comes to roofing Toronto many people are now considering flat roofing as a better option compared to the contemporary roofing design.
However, it is also vital to know that flat roofs are more high maintenance than the other regular roofs. They require more work too. They may be simpler to build, but you will sweat keeping them in good shape. If you feel you aren’t up to the task yet, then it’s safe to steer clear of flat roofs for a while. That being said, here are some six problems that you need to watch out for in case you choose to go for a flat roof for your home.
You will immediately know that your flat roof needs replacing when you notice a phenomenon known as alligatoring. When this happens, the asphalt that is used to build up your flat roof ages and loses its elasticity. This then causes it to crack and bubble. In the process, it ends up looking like an alligator’s skin.
2. Leaks and moisture
Leaks and moisture are among the most common known problems associated with flat roofs. But you can deal with leaks and moisture on your flat roof effectively. When water gathers on top of your roof from sources such as the rain, it has nowhere to escape but straight down. This also enables moisture to seep down your roof which also ends up causing you more problems. One, the integrity of your roof will definitely be compromised if you don’t address the issue fast.
3. Buckle in membrane
You may not know this yet, but most asphalt flat roofs are usually constructed like you would see in shingled roofs. Meaning that they are also made of a membrane which is soaked in asphalt. Then laid across on the top of the building. This basically forms your flat roof. So, any excessive movement or shifts in your home will also result in buckles in your roof’s asphalt membrane. In short, you will know in advance that your flat roof’s life is nearing its end.
4. Pooling water
Whenever it rains or snows and water on top of your roof, this precipitated water will basically have nowhere to escape to. Leaving it with no option but to go straight down through your roofing wall. Your roof will also shift over time. Meaning it won’t be as flat and at the same level as it was before. So, water may end up forming a pool on the side shifting more downwards. If left to linger, this pool can end up deteriorating your roof’s integrity.
5. Crack in roof
Flat roofs are also known to have more pressure being exerted on them compared to the slanted roofs. And this pressure can sometimes build up so much that it becomes excessive and cause your roof to crack. The moment you start noticing any cracks on your building’s rooftop, then you should call a professional immediately to assess the situation and see what to do about it.
Like almost every other material, asphalt roofs are also known to contract and expand with changing temperatures and weather. And over time, these changes that occur from expansion and contraction can eventually cause the roof’s flashing to pull away from its edges and corners which will eventually lead to leaks on the roof.
