Build Up Vs Modified Bitumen Vs Rubber Membrane Flat Roofing
January 22, 2019

Flat roofs are one of the most popular roofing designs and yet still one of the best investments for most of the facilities. However, the type of materials used for the flat roofs depends a lot on your locality. For instance, in hot areas where rainfall is scarce, the flat roofing could be constructed with some cement or even brickwork.

Basically, this is because such materials help to deter the hot temperatures. More to that, they are inexpensive as well as easier to install since wooden materials are inaccessible in such areas. On the same note, in locations that are cold and are likely to rain more often some other materials could be used.

The major reason behind this is that: a lot of water could in some cases lead to breaking up of the stonework, cement or the concrete used in the construction of the roof. This being the case, such roofs may not be so suitable in a location that experiences a lot of rainfall. Therefore, below we will discuss everything that you would like to know about the flat roofs.

The Three Major Types of Flat Roofs

Normally, a flat roof would last up to 10 all the way to 20 years. However, when the flat roofing installation is up to very high standards, it can add a few years to the life. That is because it’s not only the quality of the roof installed that matters, with the addition of a professional touch, you will have a roof that will serve you for 20 years or more.

  1. The build Up Roof

Well, this type of low sloped roof is one that is crafted from either 3 or more layers of materials that are water resistant. More to that, these materials are alternated with hot tar as well as ballasted with a layers of what resembles the smooth and flat river stones. With this type of a roof in your premises, you get to make use of more advanced construction materials which include the membranes of fiberglass.

Pros of The Build Up Roof

  • The major benefit of having such a roof in your premises is that: the rocks used in construction are ultimately resistant to fire as well as look striking when used in windows as well as decks. In this case, it gets a lot easier to manage the overall roofing style.
  • Finally, of all the three common flat roofing designs, this happens to be the cheapest of them all.

Cons of The Build Up Roof

  • All in all, there is also a downside to this roof style. This is because it is very heavy therefore the beams need to be strengthened every now and then.
  • Also, this roof is not the ideal one for the busy homes as it has a quite weird smell.
  • In addition to that, it is very messy during installation which gives you zero chance for DIY installation since you won’t find the leakage points easily.
  • Lastly, without the involvement of professional roofing contractors the tiny gravels and rocks could block the gutters easily.
  1. The Modified bitumen

Unlike the previous flat roof style, this one is a single-ply folded roof that resembles the ice and water protections shields although its surface area is saturated with a mineral based wear. This type of a roof could be installed with the cold adhesives, the asphalts or the common torch method.

Pros of The Modified bitumen

  • The main benefit of this kind of a roof is that the peel and stick material is conducive for DIY. In that case, it could be set up by the owners of the property without much strain.
  • In addition to that, this type of a flat roof has a light colored surface that is made of minerals. Therefore, it reflects the temperature and in that case it slashes down the energy bills.

Cons of The Modified bitumen

  • All in all, there is a downside to this flat roof type where the torch down installation method happens to be dangerous. In fact, when used to install the modified bitumen flat roof type, it could easily cause a fire. In that case, this roof type is not recommended for buildings that have been already occupied.
  1. The Rubber Membrane

Also known as the EPDM which stands for Ethylene Propylene Diene Monomer, a rubber that resembles a good inner pipe. The only difference with this one is that it has a property that is resistant to harm from the sun rays. The EPDM is one type of a roof that has very easy installation procedures which include gluing, or mooring it mechanically with nails or ballasting it alongside the stone.

Pros of The Rubber Membrane

  • One thing you’ll love about this flat roof type is the fact that this roof type can be easily installed because the material is generally comparatively light as well as extremely resistant to scratches, scuffs as well as holes.
  • With this type of a roof, you will also have a very easy time patching up any leaks on the roof.

Cons of The Rubber Membrane

  • The only downside to this type of a roof is the fact that the standard dark material that is used to absorb heat and the light covered membrane will add more cost by at least 30 especially in the warmer regions.
  • More to that, this roof type happens to be two times or more expensive than the Modified bitumen or UR.
  • Finally, it is more likely to have punctures and leaks when compared to the other types of roofs that we have discussed in this article.
