Lightweight Roof Solutions for Non-Traditional Houses

Due to the shortage of traditional building materials and the necessity for rapid completion, over 400,000 houses of non-traditional construction were built throughout the country during the decade immediately following the second world war. There were more than 30 different designs including BlSF, Cornish, Tarran, Hawksley and Blackburn, the latter almost entirely in Scotland.

Their contribution to the post-war housing need estimated at 1,500,000 homes - was vital. But those that have not already been renovated are now showing their age and need refurbishment. Originally roofed with asbestos cement or other profiled sheeting these materials have reached the end of their effective life and are now in need of urgent replacement.
The problem is compounded by the fact that many designs incorporate low pitched roofs which rule out most conventional roof tiles.

One of the major problems in refurbishing these house types is in replacing the roof covering with a material that can be installed without expensive strengthening of the structure or major alterations to fascias, gutters and verges. Ideally, the new roofing material should be lightweight, durable and of traditional appearance.

Before After


The Decra Solution

For more than 30 years, the Decra system has been providing local authorities and Registered Social Landlords with the solution to their problems with non-traditional house refurbishment, against a background of more than 50 years' worldwide roofing experience.

Decra is light - one seventh of the weight of concrete tiles - and can be installed in place of asbestos cement or profiled metal sheeting, at pitches as low as it, in most cases without strengthening the steel frame or structure of the house.

As each tile typically covers 0.46m2 and yet only weighs 3.06kg, the Decra dry-fix system can be installed extremely quickly even in the most adverse weather conditions. For example, a pair of BlSF houses can normally be re-roofed inside two days with the tenants remaining in occupation.

Decra Roof Systems offers a range of tile profiles and colours all sharing a traditional appearance of tiles and slates enabling specifiers to harmonise refurbishment with the predominant roof tones of any residential area.

Decra is permanent and reliable. Approved by the Agrement Board and backed by a thirty-year weather security guarantee, Over twelve million square metres of Decra tiles have been installed in the UK and Ireland since the company was launched in 1977. That’s enough to roof 200,000 average terraced houses, of which many thousands are refurbishments of non-traditional housing.
