Your Flat Roof, Our Expertise

When it comes to refurbishing a flat roof there are several main factors to consider; overlaying the existing flat roof system, upgrading the existing roof or stripping up the entire failing system and replacing it. The Polyroof team of experts can advise you through the benefits of each option and, as a result, which one is the most suitable you your project.

We understand that our clients are often tasked with many responsibilities during a refurbishment project. Book in a non obligatory consultation with our team, Advise, Design, Support, Guarantee, our experts will guide you through every step of the process. Our aim is to optimise your time and your client’s investment. 

Flat Roof Refurbishment Challenges

 A visual assessment of your roof can sometimes not be enough to detect the issues that your roof is experiencing. When considering the best course of action for your project, the Polyroof Technical Team can arrange for a a full project appraisal of the roof to ensure that the best solution is provided. As part of your survey, our team will use testing methods such as core sampling and moisture mapping to determine the best course of action. Based upon the challenges, demands and budgets of your refurbishment project, recommendations will be provided on whether to overlay, upgrade or replace your roof.


The Polyroof range of liquid waterproofing products are ideal for overlaying failing flat roof systems. As long as the existing roof is structurally sound, dry and free from major water damage an overlay will be possible onto just about any surface. Your overlaid roof will be covered by the trusted Polyroof Guarantee.


If your existing roof build up is sound, but does not meet current thermal performance requirements, we may recommend to upgrade your roof. As well as providing a seamless waterproofing solution, insulation can be installed over the existing roof build up to increase your roof’s thermal efficiencies and meet regulations. 


If your survey provides evidence that the long-term integrity of your roof is compromised, the existing roof will need to be replaced. As a result, our team will advise you on drainage falls, thermal calculations, wind uplift and any other considerations required to replace your roof as quickly and efficiently as possible.

Building Regulations

Let our team of experts advise and support your project at every step to create inspiring, innovative roofing solutions. Building Regulations state that when refurbishing or replacing an existing flat roof covering, the replacement system must also make provision for an upgrade to the thermal properties of the roof.

Polyroof Technical Services can advise on the latest requirements, and make provision for the correct amount of insulation for your project within the bespoke specification that we provide. However, we would recommend that you seek confirmation of our advice from Local Authority Building Control before submitting the specification for tender.
