Is it Time for New Flat Roof?

By their very nature, ‘flat roofs’ only have a very slight slope and are likely to be in contact with, and therefore under attack from water longer than other types of roof. The integrity of the waterproofing across the whole flat roof surface is therefore essential. However, all roof surfaces have a natural life span, leading ultimately to deterioration, perhaps the need for temporary repair, and the need for replacement.

Common problems with flat roofs include:

Symptoms from the inside
Leaks i.e. running / dripping water.
Damp patches at the edge of the ceiling.
Damp / water damage to walls and upholstery.

Symptoms from the outside
Pooling / standing water. Water can’t drain away, and stays in puddles.
Blisters, bubbles, damaged seams and flashings on the roof surface.
Cracks holes and loose fastenings.

Barriers to flat roof “first aid”
The actual source of the leak may be much more difficult to find, or more extensive that you think. The hole / holes may be covered by gravel / objects on the roof, covered by standing water / ponding, may be in a very inaccessible / dangerous area, may be up the (slight) slope from where you are looking, or you may lack the head for heights, the physical capabilities, or the technical know how and dexterity to conduct an inspection, let alone a temporary repair.

How To Avoid Flat Roofing Worries

Inspect the flat roof surface at least twice a year, from the outside, and from the loft area checking the edges of the roof for leaks.

Minimise other contributing causes to roof damage e.g. keep gutters / drains clean, tend to nearby masonry problems.

Avoid too much climbing or resting objects / machinery on the bare flat roof surface.

Try not to use temporary repairs that are difficult to get off when it comes to replacing e.g. bitumen / tar based patches.

Your flat roof can never be TOO waterproof so don’t waste time and money on false economy repairs and replacements that aren’t going to last. For example, consider replacing with an advanced modern membrane roofing system that has a guarantee for a long period of time.

If possible, carry out flat roofing repairs and replacement before the winter months come around.

Repair / replace as soon as possible after noticing the roofing problems, ideally catch problems early.

Call a professional, preferably a flat roofing specialist.

After replacing the flat roof waterproof surface, why not find a way to use and enjoy the space for more of the year? e.g. consider a green roof, garden / terrace roof, or put attractive timber decking on top of the new roof surface. Discuss the options with your chosen roofing contractor.
