Problem Identification

The existing flat roof covering was in poor condition with splits, cracks and deterioration throughout.

Water ingress was evident throughout the roof area, affecting the retail outlet below.


The three-storey building was based in a pedestrianised town centre location and consisted of several flat roof areas at differing levels with varying amounts of projections and plant throughout.

From experience, we felt that it would have been impractical to remove the existing roof coverings due to the difficult location and it was therefore suggested that a liquid-applied weatherproofing treatment would be the most cost-effective solution.

As an approved installer of specialist liquid coatings supplied by Tor Coatings, we consulted with them to evaluate the roof areas and to provide a specification for one of their high performance systems that would be suitable for application on the felt covering to provide a guarantee.


We proposed to apply a Tor Coatings Elastaseal liquid-applied weatherproofing system in accordance with the manufacturer's specification provided.

The multi-layer system results in a seamless polyurethane barrier membrane which enabled encapsulation of every detail and provided waterproof protection throughout the roof area.

The system is cold-applied by brush or roller and can be applied whilst the building is occupied, meaning no disruption to the building’s operations.
It is also be safer to apply than a traditional torch-on felt system which is reliant on heat.

We have had many years experience successfully using this system on a wide range of roof types and would highly recommend the product.

The specified system would provide a long-term solution with a 10 year guarantee on both materials and workmanship.

It was agreed that this system was the preferred option based on all considerations and was applied during the Spring months due to the product’s temperature restrictions.
