Flat roofs are not actually flat but any roof with a pitch of less than 15 degrees is classified as flat. Due to the material used in their construction, they can be prone to problems. With this in mind, we have found some ways to ensure your flat roof doesn’t fail.
Regular Checks
Regular inspection and maintenance of your flat roof will spot issues early on allowing you to get ahead of the game and stop any serious developments.
Having a close look at the roof in the spring and autumn is a good idea although you should also check the roof after severe weather such as storms or heavy snowfall.
Many flat roofs are covered with a felt-based material and this is susceptible to blistering, splitting and ponding, which is when water gathers in dips in the felt. Dealing with these problems as they occur will help to prevent further damage or leaks into your property.
If you see vegetation growing on the roof this is a sign that there is a build-up of dirt, water, and leaf debris. This will trap moisture on the roof covering and also prevent runoff. Blistering is another issue and is caused by trapped air or moisture under the roof covering.
Most problems are easily spotted from a high vantage point such as an upstairs window or a ladder. You should avoid walking on the roof as most are not designed to hold a person’s weight.
Repairs
Repairs to any damage in the material on your flat roof should be done as soon as you notice a problem. This may be stains on the ceiling inside the property, water collecting on the roof surface or you may see splitting or punctures when you do your visual checks.
Damage caused by blistering or punctures can often be repaired by cutting out the damaged area and patching in some new material. Professional flat roofers will have the equipment and expertise to carry out such repairs.
The flat roof cost for repairs will be significantly cheaper than replacing the entire roof if the need for repair is ignored.
Ponding should never be ignored as not only will it stretch and weaken the roofing material but the freeze-thaw cycle in winter will cause further damage to the integrity of the roof.
Maintenance
One of the best ways to ensure your flat roof doesn’t fail is to carry out good maintenance on your roof. Regular inspections followed by timely repairs are the ideal scenario to protect the longevity of your flat roof and the property underneath.
Keeping the drainage outlets in parapets clear is important to allow proper runoff and any vegetation growth on the roof should be removed immediately.
You can extend the lifespan of your flat roof with regular inspections, prompt repairs and a schedule of maintenance. Always use a qualified flat roofer to carry out any work or repairs on your roof to ensure it doesn’t fail.
