Flat Roofing System: Its Types Pros and Cons

Flat roofsFlat roofing system has mainly three kinds. These three includes built up roofs, Modified Bitumen and single ply roofs. Each flat roofing system is designed to protect the roof from rain, heat and snowfall. It helps to prevent the damage to the roof which can be caused from mold, leaks and rot which can lead you to a great expense. Here is the study of three materials which can help you to decide which one to opt and which not to.

  • Built-up-roof

Built-up-roofs were the most common and preferred roofing system before the evolution of single ply roofing system. It is a very damage proof material as it applies multiple layering of tar and gravel over the roof to create a watertight seal. Some of the advantages of the built-up-roofs, so that you can analyze it properly.

  • Tried and true

It is very old method so there is no chance of experimentation. Roofers has been using this system of roofing since 100 years. Thus it is trustworthy.

  • Thick coverage

This roofing offers lot of layering. Thus your home stays protected if one layer gets damaged. Thus you are always sure about your roofs safety as it is multilayered.

  • Highly resistant

This material is durable and keeps you away from the extra maintenance expenses. It’s surface is durable against normal wear and tear.

  • Modified Bitumen

Modified Bitumen was introduced in the mid 1970s. It is nothing but roofing sheets which are made up of asphalt which is advanced with rubber or plastic which gives higher stretch and flexibility. Modified bitumen is installed in multiple layers. Generally it is installed upto 3 layers . Hot air welders are used for joining the material seams which helps in creating a watertight system. It can be also used as a cap on BUR roofing system and this roofing is also known as hybrid roof system. Some of the benefits of modified bitumen for better analysis.

  • Uniformity

There is a remarkable uniformity in the thickness of this material. The reason behind this quality of uniformity is that it is prepared under the tight control of quality.

  • Wider temperature range

It is a special quality of modified bitumen that it can bear extreme temperature changes. It is able to manage extreme rise or fall in temperature. It is better as compared to Built-up-roofs.

  • Single ply roofs

In case of single ply roofs, a layer of sheet or plastic membrane is rolled over the roof surface and then it is welded together by using hot air tools. It results in creation of permanent watertight covering which saves the roof from leaks. Here are some of the benefits.

  • Consistent product quality

Single ply material is prepared in such a way to match up the strict quality standards apart from those used in BUR’s.

  • Ease in installation

The process of installation used in this type of material is really easy and speedy.

  • Energy efficient

This material is very environment friendly. It offers light colors which are generally energy efficient. These colors are cool thus saving your HVAC costs.

  • Light weighted

It is light weighted and thus suits well in today’s construction designs which needs more flexibility.
