Asbestos cement roofs are still commonly found on commercial, industrial and agricultural buildings throughout the UK and according the UK’s Land Registry, around 75% of all such roofs ever installed remain in place today, even though most are well past their anticipated life expectancy of 25 to 40 years.

Common Asbestos Roofing Problems

Roof Lights

Many asbestos roofing issues are actually caused by problems with roof sheets, especially the Glass Reinforced Plastic (GRP) type, which degrades far more quickly than asbestos cement.

Therefore, it is often wise to replace the roof lights if they are yellowing and you can see the glass reinforcement on the outside.

With time, the GRP sheets become brittle and will once the top gel coat has degraded, can become susceptible to bird attack and cracking, which of course causes leakage.

Replacement of the degraded roof lights will bring significant amounts of light into the building, which can in turn reduce lighting bills.

Glass Rooflights (Northern Lights) are a particular problem with older asbestos roofs, as they often crack with age which in turn causes leaks.

Because they are often difficult to reach, replacement can prove to be expensive, especially when the metal frames are in poor condition.

However, there is now an economical repair option available that is available via Asbestoseal, which involves cleaning and coating the glass with Glass Protect, a polyurethane based coating that effectively seals existing cracks and protects against total breakage by effectively laminating the surface of the glass.

This stay-clean surface will refurbish old glazed roof lights with relative ease.


Guttering, particularly valley gutters on large roofs are a major source of problems on older industrial properties, particularly when routine maintenance, such as cleaning, hasn’t been carried out.

When the gutters become blocked, the gutters can fill up and, particularly where the roof profile closers are not present, the gutter can overflow into the building.

Similarly, if valley gutters have been damaged through trafficking , impact or, in the case of metal guttering, through rust and deterioration, then leaks and their cause should be quite obvious.

In all cases, it is wise to consider these two important areas before considering major roof works – it may not be the roof itself that is causing the problem, or the issues might not be confined just to the roof.

All of the options are discussed fully on the appropriate pages, which can be reached by using the navigation at the top of this page.
