How to repair a leaking flat roof

Flat roofs constructed or installed at residential or commercial buildings have a specific lifespan. Harsh weather conditions and environmental factors, such as the sun’s UV rays, rain, extreme temperatures, and snow, can cause damage to your flat roof if you fail to maintain it properly. 

If your roof experience extensive and repeated water pooling, you need to repair it immediately to avoid further damages. Large tears, rips, or cracks can also damage your roof – so, it is wise to hire a professional roofer and fix these problems effectively and quickly. 

Other signs your flat roof needs repair are blistering and bubbling due to adhesion failure, higher moisture levels and leaks inside your home, the presence of algae, moss, mould, and lichen, a damaged topcoat, and the damaged flashing from the roof’s corners. 

Although some residential roofs use materials that can hide the damages, hiring an experienced contractor to identify the issues and fix them on time is essential. Today’s article will discuss how a professional roof repairs a leaking flat roof. Read on! 

Identify the Source of the Leak 

A skilled roofer has the right tools to locate the source of the leak from inside of your home. Sometimes, the water runs along the roof through the hole or crack and accumulates in different areas. 

So, it does not necessarily mean that the source of the leak is an area with the most water. That’s why hiring a professional is crucial to find the exact spot. In addition, the professional uses various tools to take measurements to find the leak on the roof. For example, the roofer looks for damages to the roof membrane near the vents or flashing if there is no apparent sign. 

Perform the Prep Work 

Clean your roof thoroughly if there is dirt, dust, and debris to prevent further damages. Before starting the repair work, make sure you remove foreign objects carefully, especially near the leak. Removing the debris allows you to determine whether a storm damaged the roof or the leak is due to general wear and tear. 

Dry your flat roof, especially the leak area, if there is accumulated water. The purpose is to avoid moisture build-up underneath the patch after repairing the hole. Not focusing on drying the roof can lead to the growth of mould and algae under the roof. 

Identify and Cut the Damaged Area 

The roofer will look for blisters on your roof. Blisters on your flat roof mean air or water has seeped between the different roof layers. The roof may also check for holes and cracks to determine whether the sun’s UV rays have caused the damage. Identifying the type of damage allows the roofer to use a suitable repair method. 

Cut through the damaged membrane if the leak in your flat roof is due to a blister. That way, you can remove the moisture. Our qualified and skilled roofer will cut away all damaged membrane layers without affecting the felt underneath the roof. The roofer will then dry the damaged area before carrying out the next step. 

Applying Roofing Cement 

The roofer will apply the roofing cement to the leak after peeling back the membrane layers cut previously. The purpose is to use the adhesive on the membrane flaps, leading to enhanced resealing of the cut. 

After laying down the flaps of the blister, our roofer will nail them to the roof. It secures the flaps in place and seals the leak. Next, the roofer will use the cement to cover the nails, cracks, or holes. Contact us today for reliable, quality, and affordable flat roof repair services.
