Flat Roofing Installations in Farnham | Prevent Leaks with These Maintenance Tips

Flat roofs offer a sleek and modern look for homes in the Farnham area. However, proper maintenance is crucial to prevent leaks and ensure the longevity of your flat roof. Without effective care, a flat roofing installation can be more susceptible to leaks than a pitched one, so staying on top of maintenance is important.

Regular Inspections

Regularly inspect your flat roof for signs of damage, such as cracks, blisters, loose seams or ponding water. You might be able to see the roof out of an upstairs window, allowing you to inspect the surface easily. Alternatively, you could use a ladder to get a good view of the roof. Make sure to inspect the flashing around vents, chimneys and other features.

Identifying potential issues early can help prevent leaks and minimise costly repairs.

Address Ponding Water

Flat roofing installations are more susceptible to ponding water, often caused by:

If you notice areas where water pools after rain, contact a professional roofer to prevent roof deterioration and leaks. Repairs may involve adjusting the slope of the roof or installing additional drainage outlets to prevent standing water.

To prevent blocked gutters from becoming an issue at your Farnham home, clear debris, leaves and other obstructions from drains and gutters regularly to maintain a properly functioning drainage system.

Repair Cracks and Blisters

Cracks and blisters are other common problems with torch-on felt flat roofs. These allow water to penetrate and cause leaks, so it’s important to watch for them and repair any cracks or blisters as soon as possible.

You might be able to repair small cracks yourself by:

Blisters may need to be cut open, dried and repaired using similar methods. While DIY repairs are possible, we recommend hiring a roofing contractor for high-quality flat roofing repairs you know will last.

Keep the Roof Clear

The horizontal surface of flat roofs allows leaves, twigs and other debris to collect more easily. If left, they can build up and cause the roof to be constantly damp, leading to mould, algae and structural weakness.

Clear the roof as often as needed using a broom or your hands. More frequent cleaning might be required in autumn as leaves fall from the trees. If there is moss, algae or lichen on the roof, contact a professional roof cleaner in the Farnham area – these organisms hold onto water and can damage the roof.

Prune Nearby Trees

Overhanging tree branches can drop leaves and twigs onto the roof and scrape against your EPDM rubber roofing, damaging the surface. Branches can even puncture flat roofing installations by rubbing or falling.

Prune any trees that are too close to your roof to prevent such issues. Monitor nearby trees so you can be proactive with tree care in order to avoid damage.
