A typical flat roof is prone to blisters and alligatoring, which result in considerable damages over time. Blisters can happen in all roofing materials, except for concrete tiling or stiff clay, which aren’t generally used on flat roofs. However, there’s a way to repair these problems and prevent them from re-occurring.
While major maintenance and repair jobs are best left to the professionals, here are some easy-to-do blister repairs that you may want to consider:
Clean the area to remove any dirt
Clean the area by sweeping all the dirt and gravel away. Collins Roofing Inc notes that doing so will help you in applying a coating membrane on your flat roof in Utah later.
Release the pressure from the blistered area
You may use a utility knife to release the pressure coming from the bubble. You need to cut away the roof membrane, so you can reapply the membrane material later.
Feel if there’s any moisture inside
Once you’ve removed the bubbles from the blistered area, you may now try to feel if there’s water inside it. If you feel any moisture, you must look for possible sources of leaks along the area and fix them right away. If you think you can’t handle the job alone, call a professional.
Reapply the membrane material
You may then try to reapply the new membrane at least six inches around the blister’s edges. Doing so will ensure that there won’t be any moisture inside the newly applied membrane material. It’ll also ensure that it will remain leak-proof even after it contracts and expands due to varying temperatures.
Repairing the blisters on your flat roof can reduce the chances of even more expensive repairs in the future. You must always ask a roofing contractor to check your flat roofs regularly to keep it in tiptop shape.
