Abstract

Choosing the right method of repair for a defective flat roof is as important as choosing the right roofing system in the first place. In many ways, repair probably calls for a greater level of skill than starting from scratch because there is no standard solution - each roof must be treated as an individual problem. Repairs to a flat roof can mean anything from a patch to total replacement. Part 2 advises on how to repair defective bitumen felt and mastic asphalt flat roofs. Many sound roofs are renewed when a repair would be sufficient - and there are many excellent techniques and products available to make minor repairs. Patch repairs of the covering can also allow time to organise re-roofing at the right time of year. But repairs are worthwhile only if they are cheaper than the effective cost per year of a new roof covering. If the problems are due to normal ageing, or to bad design, materials or workmanship, it makes sense to re-roof. It also gives an opportunity to improve the roof's performance. The first essential is to find out the cause of failure; this was discussed in Part 1. This Part considers the various levels of repair that could be needed and the most appropriate remedies for both bitumen felt and mastic asphalt roof coverings.
