Inspecting your flat roof before the seasons change can be most beneficial, particularly before winter and summer as we can experience extreme cold and heat that can take its toll on the materials.
Cold temperatures, storms and rain all contribute to the damage of the roofing. In the summer, the solar UV radiation is higher so the roof can be exposed to high heat and thermal shock due to sudden cooling if it rains. Inspecting flat roofing is particularly important after harsh weather as rainfall can settle and create ponding across the roof, causing water damage.
Firstly, you should check the interior of the building. Signs of water staining on the walls or ceiling will show that there is possibly a leak allowing water to get in. you can usually tell if there is a leak as a dark ring of discolouration form around where the water is leaking from. However, this doesn’t mean that the leak is coming from directly above as there are many layers of the roofing that can change the direction of the leaking water. If you have any signs of leaks from the interior of your building, this shows there is deep water damage and a roofing contractor is needed for repair as soon as possible.
It is still important to inspect the exterior of your roof even if you do not see any obvious signs of leaks from the inside. Any cracks or splits in the roof that are allowing water to get in should be dealt with before they cause further internal damage. Simply doing a walk around your flat roof each month is beneficial for a quick inspection, however it is important to be careful where you step as this could cause more damage to areas that are already impaired. If the roof surface feels weak as you are walking along it, this is a sign that the roof isn’t performing to its required standards and should be looked at by a contractor. Always be aware of where you are on the roof and never walk backwards.
Things you should look out for:
- Blocked drainage / gutter systems
- Edge metal damage
- Holes / rips / splits / separations in roofing material
Most leaks occur when the roofing material is deteriorating with age. Any penetrations in the roof such as pipes and flashings are more prone to leaks as they cause a break in the roofing material. If the seals wear away then water can flow through. In the winter, leaking water will expand when it turns to ice. This causes the crack to expand and creates further damage to the roof.
