When constructed to exacting standards by flat roof specialists, as well as properly maintained, your roof will not have any problems, but it is important to know what telltale signs to look for to ensure your roof lasts for years.

Contrary to the name, flat roofs technically are not flat; legally they have to have a small imperceptible incline to allow water to efficiently flow into a drain or gutter, Your roof’s waterproofing will also help with this to keep water moving.

However, if water begins to puddle or pool on your roof, that can be a sign that the roof has either shifted or there is a problem with the waterproof surface. Drain the water as soon as possible to avoid it seeping into your room.

To ensure a flat roof is as flat as possible, the drainage system is often designed to fairly precise specifications. As a result, it is vital that the drains and gutters are clean, clear and well-maintained to avoid potential pooling issues on the edges of your roof.

An issue that is sometimes seen with certain times of roof membrane is when moisture or air gets trapped between the layers, which creates blisters that stretch over the summer as the sun heats the roof up.

Keep an eye on the blisters and make sure they stay intact. If they do break, cut away the blistered material and reapply new membrane material, extended to over six inches past the edge of the blister.
