Roofing – Flat Roof Materials Explained

[ad_1]

As far as  roofing  options for a flat base are concerned, there are many. In the end, it really all comes down to a matter of personal choice pertaining to what type of material you decide on. Though, there are some types which are better suited for different seasons, budgets, and climates that may affect your end decision. In this article we will outline the three most common types of flat  roofing .

Built-Up  Roof 

The BUR  roof  is the traditional hot tar style that was once quite popular. This material is by far the cheapest solution available and is applied by layering 3 or more stacks of waterproof material with hot tar sandwiched between them, before ballasting the top layer with an additional layer of gravel-type pebbles.

While this method can be very attractive as well as cheap, it is also harder to maintain. Leaks prove rather difficult to location, and often the joists must be straightened in order to hold the bulk weight of the  roof . The work must be completed by a professional and is extremely messy. Sometimes gravel will clog the gutters of the surrounding gutters after a heavy storm, thus adding to the maintenance factors.

Ethylene Propylene Diene Monomer

EPDM  roofs  are made from rubber  materials . These  roofs  are very durable and look quite a bit like the rubber used in inner tubes. There are 3 separate methods used to install; using fasteners, or having them ballasted or glued down.

Maintenance is rather low. Leaks are fairly easy to patch and the material is known for being light weight, but very durable. The black type soaks up a large amount of heat, and is thus, not recommended for hotter climates.

Modified Bitumen

The type involves the attachment of a single ply one, integrated with a mineral-based shield, to the surface of the  roof  itself. Typically, two types of materials are used: torch-adhesion type and the peel and stick method which is much more simplistic.

It is quite possible to perform the peel and stick variety as a DIY task. In addition, the type of material used can greatly reduce heat and energy bills. Even better, it is moderately priced.

When considering your next flat  roofing  installation, it is very important that you consult a professional prior to installation. In this way, you can ensure that the job is done in the correct manner, thus adding to the security and durability of the  roof  for years to come.
