Supermarket Flat Roof Repair

This article shows how Rubba-Roof was used on a commercial building flat roof repair.

It is a sad fact that pubs are closing down all around Britain. The recession and changes in social strata and in drinking habits has led to a glut of pubs coming on to the market for sale or lease.

Many are unfortunately left standing empty due to difficulties in reletting or gaining change of use permissions. Empty buildings can rapidly deteriorate and owners are often unwilling to spend money on maintenance without the prospect of revenue.

Some of these closures do result in happier endings because the supermarket giants have recognised their potential for conversion into smaller ‘convenience units’. One such is a large public house in Hornchurch. Occupying a dominant corner site, with a generous frontage lying behind the public footpath, the old Elm Park Hotel is being remodelled and will soon be opening its doors again in its new format.

The rear of the building is a single storey extension with a large flat roof and parapet which the new owners needed to be assured would give no problems for many years.

Rubba-Roof was specified to repair the flat roof and provide a flexible, waterproof membrane over the existing felted and asphalt surfaces.

Cutting FleeceA particular feature of interest in this project is the usefulness and adaptability of Rubba-Roof Reinforcing Fleece.

The joints between the flat roof surfaces and any surrounding parapets are always a potential point of failure. Although most will have had flashings, either felted or lead, incorporated when the roof was constructed, the passage of time and weather will often have degraded these and water ingress can make its way between masonry and roof surfaces. Once water has found its way in behind or under flashing strips, the freeze–thaw cycle and expansion as a result of high summer temperatures can lead to flashings lifting or peeling.

Rubba-Roof compound, used with the special Rubba-Roof Reinforcing Fleece, makes it simple to achieve renewal of joints at parapets and upstands on flat and low-pitched roofs.

Important Tip

As with all liquid rubber roof coating projects – careful preparation is vital to a successful result.

You can see here that the flat roof areas were encumbered with debris. The Rubba-Roof installers took care to thoroughly clean the working areas.

The photograph below shows part of the flat roof after the application of a 1mm thick coat of Rubba-Roof.

Note the seamless membrane that has been achieved around and over the central raised roof dias. This sort of detailing is so easily done with Rubba-Roof cold applied, liquid coatings.

So, a happy and useful transformation of a redundant building to serve the local community. From watering hole to convenience store – but with no watering holes (at least, not in the roof!).
