Advantages of Roof Surveys

There are many types of flat roof substrates used on commercial property in the UK, including felt, concrete, metal, timber, asphalt, single ply systems and more.

Each substrate type has its own advantages and disadvantages, but when a leak occurs one any type of substrate, the result is the same – water inside the building!

Liquasil’s flat roof waterproofing systems are designed to prevent leaks and they are very effective at doing so.

However, before rushing to completely refurbish a flat roof, it’s wise to get it surveyed.

A flat roof survey by an independent and suitably qualified firm (not a roofing contractor) will diagnose any issues on the roof that could be causing water ingress.

This could range from breaches in the current covering, such as felt or single ply, to something as simple as a loose coping stone on a parapet wall.

Just because there is a leak, it doesn’t mean that you have to completely renew the roof covering – though as roof coating manufacturers, we’d like to think you might consider our products.

Before we accept any flat roof waterproofing project using our products, we like to inspect it to make sure that once complete, the roof wil no longer leak.

This allows us the opportunity to examine other aspects of the roof that mightneed attention during the coating works. It also allows us to consider things like flues, drains, upstands, parapet walls and of course, the condition of the structural deck itself.

Nobody wants their waterproofing system to fail, so its best to choose a manufacturer who cares enough to perform some due diligence before a contract starts.

 

Flat roof waterproofing – we strongly recommend a full roof survey, including core sampling to make sure that your waterproofing solution is specified correctly.
