Flat roof repair: You Should Know 7 Ways to Repair a Flat Roof 

Flat roofs are a common feature in commercial and residential buildings. They offer many benefits, such as increased living or storage space, easy access, and easy installation. However, flat roofs are susceptible to damage over time like any other roof. It can be caused by weather, wear and tear, or poor installation. When your flat roof becomes damaged, it’s important to repair it as soon as possible to prevent further damage and costly repairs. Here are seven ways to flat roof repair.

Inspect the Roof Regularly

The first step to flat roof repair is to inspect the roof regularly. Doing so lets you catch any damage early and prevent it from worsening. During the inspection, look for signs of damage, such as cracks, tears, or bubbles. You should also check for water stains on the ceiling or walls, a sign of water damage. If you notice any damage, take note of it and plan to repair it as soon as possible.

Clean the Roof

Before you begin the repair process, cleaning the roof thoroughly is important. It will help you identify any damage and ensure the repair materials adhere properly to the roof. Use a broom or a pressure washer to remove any dirt, debris, or leaves that may have accumulated on the roof. Be careful not to damage the roof membrane during the cleaning process.

Repair Cracks and Tears

Cracks and tears in the roof membrane can cause water to leak into the building, leading to further damage. You must clean the damaged area and apply a patch to repair these. You can use various materials to patch the roof, such as a peel-and-stick patch, roofing cement, or a liquid membrane. Ensure the patch is large enough to cover the damaged area and properly adhere to the roof.

Fix Blisters and Bubbles

Blisters and bubbles on the roof membrane are caused by trapped air or moisture. Over time, they can lead to cracks and tears, which can cause water to leak into the building. To fix blisters and bubbles, you must cut an X-shaped incision over the blister or bubble and remove the trapped air or moisture. Then, apply roofing cement to the area and smooth it out.

Replace Damaged Flashing

Flashing is used to seal the roof against the wall or chimney. It is also used around skylights and vents. If the flashing becomes damaged, water can leak into the building. To repair the flashing, you will need to remove the damaged flashing and replace it with new flashing. Ensure the new flashing is the same size as the old one and properly sealed.

Apply a Reflective Coating

A reflective coating can help to protect the roof from the sun’s UV rays and reduce energy costs by reflecting heat away from the building. To apply a reflective coating, clean the roof thoroughly and apply the coating using a paint roller or a spray gun. Ensure that the coating is evenly spread and covers the entire roof.

Seek Professional Help

Flat roof repair can be complex and dangerous, especially if you need to familiarise yourself with roofing techniques. If you are unsure how to repair your flat roof or are uncomfortable working at heights, it’s best to seek professional help. A roofing contractor can inspect your roof, identify any damage, and recommend the best repair solution for your roof.
