If you have a property with a flat roof, you may have heard that flat roofs are prone to problems. In theory, a well-built flat roof should be no more trouble than a pitched roof, but poor construction or neglect can lead to significant problems.
Why Gravel Is Used
Gravel or stone chippings are often spread on flat roofs to protect the roofing membrane from UV rays, which can make roofing materials dry and brittle over time. Gravel also acts as ballast, weighing the roof covering down and reducing the risk of damage in high winds.
Getting the Installation Right
On traditional built-up felt roofs, chippings need to be properly bonded to the surface, usually by bedding them into hot bitumen or a suitable adhesive. Loose chippings scattered on a dry surface will simply wash or blow away. This is why it is so important to use an experienced professional roofing company.

Coping with Wind
Flat roofs are often more exposed to the wind than pitched roofs. If the roof covering is not properly fixed and weighted down, strong winds can lift it, leaving the roof deck exposed to the weather.
Regular Checks
Check your flat roof regularly for pooling water, cracks, blisters and loose edges, and clear gutters and outlets so that water can drain away. Catching problems early can save you a costly repair.
