Flat Roof Development

Flat Roofs are still a common feature in the UK. They are simply designed with your chosen material upon a particular Sheet Timber, usually Plyboard or OSB. These materials are supported by your Joists underneath which span the length of two walls. Most of the time, depending on the location of a Flat Roof, these joists are boarded and plastered, making it quite difficult to check the condition of the boards towards the end of their life. Getting a repair done on your Flat Roof is definitely an option, however once you start noticing wear and tear on your flat roof (ie, blisters, cracks and peeling) it's probably about time to look for a new alternative. 

Cestria Roofing have a dedicated Flat Roofing Division employed specifically to install the material of your choice. The 3 most popular options are also the highest quality options and our team have collectively installed thousands in their experience.

Bitumen Based Felt

This is sometimes referred to as "Torch on" as it requires a.. you guessed it.. blow torch to generate the right amount of heat to fix to your boards. Typically it’s applied as a 3 layer system usually consisting of a perforated underlay, a 2mm underlay layer, then thick 4-5mm felt . It is certainly the most short lived material, normally lasting around 15 years if it's been fitted correctly. It is still highly popular as its the cheapest option and does the job its designed to do.
