The types of materials
that are used in the making of flat roofs all differ greatly with their
qualities and inefficiencies. Here are just a few of the most popular materials
and the pros and cons;
- Felt
- This is the most popular form for flat roofing systems in Rayleigh SS6 8
because it’s cost efficient. It can be used on any type of roof and has
been used for many years with proveable results. The disadvantages are
that it is not the easiest to repair yourself and it needs heat to install
as bitumen is melted over the seams.
- Asphalt
- Has a long life span thanks to its durable construction and is still
fairly cheap to purchase. The negatives are that because of its overall
weight it needs a strong foundation to support it, it’s fairly rigid, and
it is not easy to repair yourself.
- EPDM
Rubber - Hard wearing, flexible and lightweight making it incredibly
simple to install. The downside is that rubber can shrink over time
causing complications with leaks and it is not the most attractive
material to look at.
- GRP
Fibreglass - Very easy to install thanks to its lightweight composition.
Also very hard wearing and looks nice and is vandalism resistant. The
negatives are it does not not work well on large surfaces and is pretty
inflexible.
- Single
ply membrane - This is any material that can be applied as one layer as
opposed to the multi-layering of something like felt, such as PVC TPO and
PIB. They are all lightweight and flexible and can contour around
difficult shapes easily. However, they are more expensive to install than
other more traditional materials.
