Different Types Of Flat Roofing Systems

In the recent past, flat roofing options have become popular. Business and homeowners are preferring them mainly because they wear better compared to older material. Their long-lasting nature (can last up to 25 years) makes them a darling of many.

Different types of flat roofs exist. The 5 most common ones are:

  • Build-up roofs
  • Modified bitumen roof
  • Rubber membrane roof
  • Spray polyurethane foam roof
  • TPO or thermoplastic membranes

Build-Up Roofs

These are simply the conventional hot-tar-and-gravel roofs. They are built from 3 or more layers of waterproof material. The material is alternated with hot tar coupled with a ballasted layer of fine river stone.

Initially mostly made of tar paper, today’s build-up roofs are gradually utilising more-advanced materials like fibreglass membranes. Of the different types of flat roofing systems, built-up roofs are the most affordable.

Another great highlight about them is the fact that they are attractive for decks and windows that overlook the roof. You can also settle for this option because of its impressive fire-resistant nature.

The drawback of built-up roofs is the fact that they are messy and smelly to install. These roofing systems are also heavy. 

Modified Bitumen Roof

Modified bitumen roof is a solo-ply rolled roofing system that is akin to an ice-and-water buffer. It features a wear surface that is mineral-based.

The torch-down roofing systems entail heating the adhesive as you unroll the material. Today’s peel-and-stick roofs are easier and safer to install.

This option is the best for those that desire an easier to install the type of flat roofing. Another striking attribute about this type is that its light coloured mineral surface normally reflects heat and minimises energy bills.

Its downside is that its torch-down application can be a fire hazard.

Rubber Membrane Roof

The rubber membrane roof is made of authentic rubber. It’s engineered in such a way that it resists damage from sunlight. Professionals mechanically anchor these types of roofs with fastener and then glue or ballast them with stone.

The fact that their leaks are effortless to patch makes them loved by many. Secondly, they are easy to install. The material of this type of roof is relatively light although highly resistant to tears and scuffs. Patching their leaks is a walk in the park.

Because its standard heat-absorbing material is expensive, it adds around 30% of its total cost. Another drawback is that it is more vulnerable to punctures in comparison to other choices.

Spray Polyurethane Foam Roof

With the spray polyurethane foam roof, you get to enjoy a seamless roofing system that does not have cracks, seams, and joints. It prevents any issues related to cold, heat, and moisture. On top of that, you get to enjoy a superior insulating power.

If you want a roofing system that enhances the ability of your roof to resist severe weather, you should consider this one.

TPO or Thermoplastic Membranes

Thermoplastic roofing membranes are mechanically attached to plates and screws. Experts can also adhere them just like with EPDM rubber roofs. They come in different colours such as grey or white.

From a distance, TPO and PVC membranes are difficult to differentiate. They give you building a tight look that resembles rubber roofing.
