When it comes to flat roofs, not every roofing material is appropriate. Usually, materials used on flat roofs need to be more water resistant and durable. For instance, you wouldn't use wooden shakes or terra-cotta tiles on a flat roof. A flat roof is going to experience standing and pooling water, so there cannot be any gaps or areas where water can seep through. Additionally, when it comes to flat roofs, building owners usually aren't too concerned about the style. That is, the roofing material isn't visible from the ground, so it doesn't really matter how it looks. Most building owners are more interested in having a low-maintenance and durable product, rather than having a material that is stylish. This article compares two great materials for flat roof construction: asphalt tiles and spray foam roofs.
First of all, it is important to note that these materials are only used as surface covers for the roof deck. That is, they don't make up the roofing structure. Whether you have wooden or concrete roof decks, these surface materials can be added on top.
Asphalt tiles are used in all types of roofing construction because they are so adorable. Asphalt tile is basically like a sticky piece of sandpaper. Of course, it is far more durable and weather resistant. The pieces are affordable, partly because they are lightweight and very easy to install. They are basically applied to your roof like a sticker. This is something to consider if you are planning on handling your own installation.
Spray Foam Roofs
Spray foam roofing products are also popular for flat top buildings. Basically, a durable layer of foam is sprayed on top of your existing roof material. This foam dries to be hard, like a solid layer of rubber. This creates a waterproof seal that protects your existing roof deck. It is even more water resistant than an asphalt roof.
Usually, the foam will be white, but it can also be painted once it dries. It is much harder to paint an asphalt roof. So, if you want a different color on your foam, the possibilities are endless. The application of the spray foam is definitely something that needs to be done by professionals. But it is very affordable material and installation is simple.
Both asphalt tiles and spray foam can add an important protective layer to your existing roof. They may not be the most attractive products, but they are both durable and perfect for flat roof renovation. To learn more, contact a company that handles commercial flat roof installation projects.Share
