Most commercial buildings are constructed with flat roofs made of asphalt or metal. These types of roofs often have a shorter lifespan than pitched roofs, which means building owners must be vigilant about any potential damage. Unfortunately, flat roofs can be somewhat more difficult to evaluate, which is why it is important that you know the signs that could indicate the need for flat roof maintenance or repairs.
1. Leaks & Water Damage
Flat roofs are often more susceptible to water damage because they lack the same easy drainage as pitched roofs. Flat roofs, especially larger ones, should be outfitted with proper drainage systems when it rains, but if these systems fail or become blocked, it could lead to significant water damage. If water is left to pool on your roof, it could begin to break down sealants and moisture barriers, leading to interior leaks within the building or moisture damage in the roof itself. You might notice water damage when your roof leaks or when wet spots or mold begin appearing near the roof or in the roof space. Also, if water fails to drain from your roof, you should also seek immediate repairs.
2. Exposed Undercoat
When the outermost stone or tar layer of your flat roof peels away or lifts, it could expose the undercoat of your roof. The undercoat is far less resistant to foul weather and can be easily damaged when exposed to the elements. This can cause the undercoat to tear and pull away if the issue is not immediately repaired. If you notice any lifting or peeling on your roof’s outer layer, make sure you call a roofer immediately.
Most asphalt flat roofs are constructed with a membrane, which can buckle when the building shifts. Buckling might occur because of the building’s age, but any external force or fallen object could also cause it to warp in this way. If you notice your roof losing its structural integrity, it likely needs serious repairs.
4. Cracks and Fissures
Roofs can develop cracks for many reasons, but the most common one is pressure. Flat roofs often sustain more pressure than slanted roofs, which can lead to cracking on the roof itself and near the sides. Structural damage to the commercial building itself can also cause the roof to crack.
5. Damaged Panels
Some commercial roofs are constructed with panels. When these panels drift or slip, either due to age, weather, or some other type of damage, it can make your roof unstable. Sometimes debris or water can get beneath the outer panels, causing them to lose stability, creating an additional hazard. If you notice your flat roof panels lifting or slipping, make sure you make the appropriate repairs quickly.
