Flat Roof Repairs: Effective Methods To Restore Your Roof

29 August 2023 by Leslie Turner

Flat roofs, while aesthetically pleasing and space-efficient, can present unique challenges when it comes to repairs. Their slight gradient makes them prone to pooling water, leading to potential leaks and damage. Regular maintenance and timely repairs are essential for increasing the lifespan of a flat roof. Here are some effective methods for performing flat roof repairs:

Method 1: Patchwork

Small punctures or cracks can develop on a flat roof due to various reasons, such as falling debris or foot traffic. For these minor damages, using a patch is often sufficient. The process involves cleaning the affected area, applying a primer, and then adhering a patch made of the same material as the roof. This is then sealed to prevent water infiltration. Roofing cement or specially designed adhesive tape can also be used to ensure a tight seal.

Method 2: Liquid Roofing 

Liquid roofing is a method where a high-performance liquid roof coating is applied over the existing roof surface. This method is especially useful for roofs with many protrusions or complex machinery, as the liquid can easily navigate around such obstacles, ensuring a seamless waterproof barrier. The liquid roof coating not only repairs the existing damages but also offers additional protection against UV rays and adverse weather conditions.

Method 3: Reinforced Bitumen Membranes (RBM) 

For flat roofs that have sustained a bit more damage, reinforced bitumen membranes can be an effective solution. RBM consists of layers of bitumen, which are alternated with reinforcing fabrics. This creates a waterproof barrier over the damaged roof. The layers are torched or bonded onto the roof, providing a flexible and long-lasting protective shield against water.

Method 4: Full or Partial Replacement

In cases where the flat roof has sustained extensive damage, it might be more cost-effective to consider a full or partial roof replacement. This would involve removing the damaged sections or the entire roof, inspecting and repairing the underlying structure, and then installing a new roofing system. This method is more labor-intensive and costly but is essential when the damage compromises the structural integrity of the roof.

How To Avoid Repairs In The Future

To avoid significant repairs, regular maintenance of a flat roof is crucial. This includes routine inspections, especially after heavy rain or storms, to check for pooling water or other damages. Clearing debris, ensuring the drainage system is functioning correctly, and addressing minor issues as soon as they arise can prevent more severe problems in the future.
