Flat roof maintenance refers to work carried out on a roof to prevent wear and tears and make sure that the roof continues to perform at its optimal performance. It is really important that flat roof maintenance and inspections are conducted twice a year, or following extreme weather. This will determine if there is anything that needs to be repaired or replaced.
Look for obvious signs of damage
You will be able to see any obvious rips, tears or cracks where water may be able to enter the roofing system and cause damage to the property below. Be mindful though that there could be damage that you can’t see. Water will find its way in through any small crack or hole.
Remove and debris
Debris that is blown on to the roof by the wind can scratch, tear or cause other damage to the roof. If you see any debris on the roof, it needs to be removed at which point you can give the roof a quick visual inspection to see if there is any damage sustained.
Inspecting Seams & Membranes
Particularly on felt roofs and older systems, where 2 pieces of material are joined, these seams and membranes can be vulnerable to leakage. Pay particular attention to areas around skylights, roof windows, air conditioning units and air vents. It is not just storm damage and rain that can cause the issue – the sun’s UV rays can break down the membranes which can lead to problems.
Replacing damaged flashings
Where two opposing surfaces meet, flashings are installed to provide extra protection. This flashing adds a further barrier to try and prevent water leaking into vulnerable areas. These flashings can become loose or become damages from their regular exposure to water and require replacing
Clear gutters and downpipes
Make sure that all guttering and drainpipes are kept clear and that they are cleaned out regularly. If the water can’t run off, it will eventually cause damage to the roof.
Look for blistering
Roof blisters are raised, spongy looking spot son the roof which occur when air becomes trapped between the layers. Water can enter when the blister pops and damage the roof.
Standing pools of water
After heavy rain, you may discover standing pools of water that just sit on the flat roof without anyway of draining away. It can dry out leaving a sag, a water mark or a dirt thing. If you notice these marks in dry weather, it means that the water has been pooling regularly and you need to look at a more effective draining system.
Check for splitting & cracking
Any cracking, splitting or visible damage needs to be seen to sooner rather than later. This is how water will enter the roof. Patching it up or trying to repair it yourself is just like putting a plaster over something and it will only be a short while before you are experiencing further issues.
