Flat Roof Replacement & Repair

If your current flat roof is old and you can see dampness or leaks coming through, it's time to look at replacement.


Ploughcroft offers a range of flat roof systems for all types of spaces and budgets with a life expectancy of up to 30 years.

Refurbishment or replacement of a flat roof is likely to be reportable to Local Authority Building Control (LABC). Part L of the Building Regulations requires additional thermal insulation to be installed when replacing the decking of a roof which is above a heated space. The new roof must achieve a U-Value of 0.18W/M2k.

As members of Competent Roofer, Ploughcroft are able to deal with all building regulations on behalf of our customers. You don’t have to worry about this compliance — because we will deal with it all!

Liquid Roofing

SIKA Verified Contractor, SIKA Aproved Installer, Liquid Plastics Approved InstallerFor large flat roofs, we use Sika Roof Waterproofing Membranes. We typically use these for the covering of existing flat and pitched roofs. The advantage here is that we can apply them without removing the existing roof covering. Being liquid-applied, they are ideal for complicated roof areas where there is a lot of detail.

Sika Roof Waterproofing Membranes are applied cold, eliminating the risk of fire during installation. It is low maintenance, and the application causes minimal disruption.

Small Flat Roofs

Firestone Rubber Roof, Firestone Installers, Flat roof replacementFor smaller flat roofs (such as extensions, garages, dormers etc.) we use Firestone RubberCover. This comes in seamless sheets, is environmentally friendly with high durability, and is also fire-resistant.

Firestone Building Products specially designed the Firestone RubberCover™ EPDM Roofing System for small residential flat-roofing applications.

The system is based on high-performing Firestone RubberCover™ EPDM rubber membranes and a limited range of accessories, offering a watertight and durable roofing solution.

Balconies and Walkways

Flat roofs that can withstand heavy traffic may be specified for balcony surfaces and walkways.

Warm Roofs

We convert flat roofs into Warm Roofs by adding extra insulation. Any flat roof above a habitable part of a house must be insulated to comply with Part L of the Building Regulations. Ever since April 2006, this also applies to the refurbishment of existing flat roofs.

  • Lower heating bills throughout the year and rooms are cooler in the summer;
  • High-tech insulated warm roof which normally achieves a U-value of 0.18W/M2k;
  • Comes with a 20-year waterproof guarantee;
  • Fully complies with Part L of the Building Regulations.

Warm flat roof construction means taking a large amount of insulation up onto your roof. So scaffolding is nearly always necessary for access and safety. Read more about our High-Level Access services here.
