Flat roofs are found on commercial roofs as well as on some residential homes and apartment buildings. They are popular for their ability to provide easy roof access to employees and service providers for such things as HVAC, communications equipment, and solar panels. They are also popular for their relative affordability. Like all roofs, flat roofs can develop issues over time. Due to their constant exposure to the elements, flat roofs have less ability than sloped roofs to shed water and debris. This extra exposure can lead to issues with the roofing material, including those within flat roofing systems, that should be addressed. Here are some of the problems that can occur over time with a flat roof.

Protecting Your Flat Roof from the Elements

Unlike a sloped roof that may not receive direct sunlight for parts or all of the day, a flat roof can’t avoid the elements. Hot sun, rain, hail, ice, and snow all beat down on a flat roof, making it vulnerable to wear and tear, and even water damage over time. Flat roofs are less able to shed precipitation, putting more strain on the roof system. While the materials on your flat roof are made to stand up to the elements, over time, especially if the roof does not receive regular maintenance, the roof will develop problems. Many problems can be fixed if caught early by your professional roofer. UV damage, for example, can be avoided by using UV-resistant flat roofing materials, such as PVC roofing, or treated by adding a reflective coating that acts as a barrier against the hot rays of the sun. This also helps to reduce the amount of heat entering the building.

Dealing with Leaks on Flat Roofs

Roof leaks are a common problem with flat roofs because drainage is more difficult on the flat surface. Water seeps into the roofing material, breaking it down and allowing water intrusion into the structure below. Your roofer will determine if the leak is locally repairable and, if so, patch it to stop further damage. He may also install better drainage systems where possible to guide water off your roof.

Pooling Water: Understanding and Managing the Risks

Pooling water, like leaks, is a product of the nature of the flat roof and the lack of easy drainage. Pooling water may cause water damage to the roof and the structure below and create issues, such as mold in the building’s attic, ceilings, and walls. It’s a good idea to regularly inspect your roof after a storm to remove pooling water. If the problem is persistent, your roofer may be able to offer solutions for improved drainage systems or other ways to manage the issue.

Preventing Algae and Other Growths on Flat Roofs

Standing water, rotting debris, and moisture that are not removed from roofing materials or the underlying membrane may develop growth of algae, mold, and even plants. This can be minimized with regular cleaning of the roof to reduce the possibility of biological growth taking hold. Regular roof inspections and maintenance by your roofer will help identify and correct problem spots before algae can grow and damage the roof.

Structural Movement: Maintaining Stability in Flat Roofing

Your flat roof naturally expands and contracts with changes in temperature that occur both outside and inside the building, with the heating and cooling of the interior. Over time, this movement can cause the roof membrane to buckle, crack, or split at the seams and around flashing. This opens up the roof to leaks and other issues. This natural process is addressed with proper maintenance to minimize damage, and replacing a worn-out roof when damage cannot be fixed due to age.

Dealing with Cracks and Blistering in Flat Roofs

Cracks in a flat roof can develop from structural movement and from pressure on the roof. This may be from people walking on the roof, the weight of heavy equipment that sits on it, accumulated debris, snow, and ice, or other causes. Cracks lead to leaks into the membrane below and should be sealed by your roofer. If cracking is extensive, a roof replacement may be needed.

Blistering

Blistering can occur when air or moisture get trapped under the membrane that lies across the roof under the roofing material. Blisters can be repaired by your roofer during maintenance to prevent them from bursting or expanding with temperature changes.

Ensuring Proper Flashing Installation and Maintenance

Structural movement, also known as thermal movement, will cause the lining of the roof to shift over time. This may expose the edges of metal flashing such as vents or even cause them to pull away from the roof, leaving gaps for leaks to occur. Regular inspections will catch these situations early. However, once a roof is too old, the damage to the underlying roof materials will be too severe to be able to correct the issues with flashing and a new roof is in order.

Managing Contaminants and Debris on Flat Roofs

Some commercial buildings, such as restaurants, may emit contaminants like cooking oils that settle on the roof and cause damage over time. Similarly, debris, such as tree limbs, leaves, dirt, and other materials, can cause physical damage from impact or through decay over time. The debris may harbor moisture that leads to damage to the membrane, creating leaks, mold, and other problems. Damage can be mitigated with regular cleaning of the flat roof surface.

Whether you have a maintenance staff or rely on your professional roofer to maintain your roof, it is important to keep in mind some Tips for Flat Roof Maintenance. Carry out regular roof inspections and a maintenance schedule. The greatest benefit of flat roofing is that it is easily accessible and safe, making it simple for you to carry out regular cleanup to remove water and debris that accumulate, and to do a visual inspection for any of the above problems.

If you find any problems, call your roofer to carry out repairs. Prompt action to patch or seal the roofing material where there are problems, such as leaks, blistering, or punctures, will extend the life of your flat roof. This will also save you money from more extensive repairs down the road should the problem expand and cause damage to the building structure itself.

Whether or not your roof appears damaged, it’s recommended that you have a professional roof inspection every six months. Your roofer is trained to spot early and emerging issues and will care for your roof so that you can have peace of mind that you are getting the most from your investment in your flat roof.
