topseal new overlayTopseal have produced their Topseal Overlay system, which is a cold liquid applied membrane for the flat roofing refurbishment market. The system enables a guaranteed watertight roof without having the inconvenience of the old roof stripped off providing that the substrate is in a sound condition.

The Topseal overlay system like all Topseal systems is installed only by Topseal trained and approved installers.

Topseal overlay is not only cost effective for flat roof refurbishments, but as it is a cold-liquid applied system there is no heat or flames used on the roof and it also cuts down on landfill as the system is directly applied onto existing surfaces (felt, asphalt and concrete) which also means that the work can be done with minimal disruption and people can continue with their day to day activities in the building.

The Topseal Overlay system comes with as standard a 20 year product and workmanship guarantee; it is also available with an optional guarantee protection certificate and optional 10 year insurance-backed guarantee.

There are two options for improving the waterproofing on your roof, either strip off the failing current system or to overlay it. Topseal now has systems suitable for both these situations.

This system is currently undergoing testing for BBA Certification.
