Three Great Flat Roof Materials


A flat roof needs to be stronger than a pitched roof. This is especially true in climates with a lot of rain or snow. The weight, along with the deteriorating affect of moisture, can definitely take its toll on a flat roof. This is usually due to the fact that it takes longer for a flat roof to dry off. Water doesn't run off as freely, and standing moisture on any surface is going to ultimately cause it to wear down. This is one reason why heartier materials need to be used on flat roofs.

Luckily, flat roofs are generally more hidden and can't be seen from ground level, so style isn't as important as functionality when it comes to the material you choose. This is why most visible roofs have some sort of shingle or tile, but flat roofs have a permanently adhered material whether it is tar, asphalt, foam, or concrete. This article explains the most important differences between the three most common flat roof materials.

Spray Foam

Spray foam is an all-inclusive and affordable solution that also happens to be very practical. The best thing about a spray foam finish is that it has a smooth, colored texture so that it doesn't need to be painted. But, if you do want to paint your spray foam, it is actually very easy to paint. Spray foam is usually the softest material, which actually makes it very easy and safe to walk on, even when it is wet. When properly designed, spray foam roofs will drain well, and moisture damage issues are very rare.


Asphalt sheeting is also practical on flat roofs. Large sheets of asphalt can be rolled on to pretty much any deck surface and glued down for a permanent hold. Asphalt works best on top of concrete flat roofs. Having the layer of asphalt on top can help with insulation and also make it safer to walk on the roof because of the texture provided by the asphalt.


Flat roofs that have exposed concrete can definitely be durable, but they also need to be properly designed so that there is no pooling water. If the draining system is not working, you could have issues with water soaking into the concrete and eventually causing it to crack. This is usually a very long-term issue and one that takes years to actually cause problems.

Ultimately, any of these three solutions could be perfect for your flat roof. Work with a commercial roofing company like Christianson Roofing INC to find the best optionf or your needs.
