Roof Refurbishment – Hove Court, Lee, Hants

A large residential block close to the seafront in Lee-on-the-Solent, near Gosport , is often subjected to harsh weather conditions. As part of a major external refurbishment and thermal upgrade of the building, it was found the 1000m2 roofs did not have any insulation and the existing felt covered roofs had severely degraded and required removal. Additionally, the roof deck did not meet current Building Regulations standards.

Product brief:

Gosport Borough Council opted to remove the existing coverings and over-deck with new WBP plywood. The council then specified a new cold installed Proteus Pro-Therm Insulation and Proteus Pro-System® seamless waterproofing Built-Up Roof. This provided the most suitable, as well as fast, reliable and high quality solution to extend the lifespan of the roofs within a tight budget.

Key Requirement: High Performance Waterproofing

The roofs were allowing water ingress and required a low maintenance waterproofing overlay. The drainage detailing was changed by removing one perimeter kerb and introducing an external gutter system, so blocking off problematic internal down-pipes. Proteus Pro-System® does not have any joints and minimal maintenance is now required on the roofs.

Key Requirements: Health and safety

Working on occupied buildings, particularly in crowded towns and cities, safety is always of utmost importance. Proteus liquid applied systems are cold installed and meet all health and safety criteria to work on this occupied building whilst minimising the risk of fire. The roofs have a timber deck structure and detailing, support beams as well as other potentially flammable building materials which meant the use of the cold installed Proteus Pro-System® Built-Up Roof removed the risks posed by heat or open roof torch flames.

Key Requirements: Durability

Proteus Pro-System® waterproofing system offers 10, 15, 20 and 25 year durability options which are also available with independently provided insurance. A range of roofing system solutions are available including inverted roofs, green roofs and podium decks.

Key Requirements: Quality Control

Proteus Waterproofing worked in close partnership with its Licensed Contractor to successfully deliver the project to a very high standard and provide the client with long lasting solution.
