If you are planning to build a garage or some other building on your property, and you are in the process of deciding which type of roof to put on it, you may be wondering if a flat roof is the way to go. Well, it can be, but it depends on how you do it. Let’s go into that for a second:
Traditionally, flat roofs were used as a design solution in dry areas. You see it in traditional buildings in the Middle East, in African countries and anywhere else people live in dry or desert-like surroundings. The reason why it works here, is because heavy rainfall rarely is an issue. Whenever rain does fall, it usually doesn’t deposit enough water on any flat surface, that a puddle will remain for a long time.
In much of the northern hemisphere however, it is a different story. Here, we typically have a considerable amount of rainfall, and snowfall in the winter. A completely flat roof is hardly practical
in this kind of climate, as water and snow will deposit and slowly enter the underlying construction – which would be your living room. Nevertheless, it is possible to have a roof that is nearly flat, without experiencing severe water damage.
Roofing materials such as roofing felt or roofing sheets are often used for a flat roof design. Even though many of these are very easy to use, it would perhaps be a good idea to hire a professional roofing service to install it, as these people will know how shallow and angle the material can be mounted at without risking water damage. It would be a good idea to request that a roofer let you know in his roofing quote to you, whether or not your choice of roofing material is realistic for installation at a shallow angle. Not all roofing materials are suited for flat roof construction, so don’t expect to be able to have a slate roof at under 10°, or something like that.
Of course, many will be able to install a flat roof themselves, or do flat roof repair themselves, but it does require of you that you carefully read datasheets on roofing materials, and that you carefully follow any instructions given by the manufacturer of your chosen material. If you don’t, you could end up with a perfectly flat, and perfectly useless roof.
