Flat roofing systems are cost-efficient and easy to maintain. In spite of the benefits of this type of roof, the materials that comprise a flat rooftop have a limited lifespan. The sun and moisture could damage the roofing membrane, resulting in a leak.

Identify A Roof Leak

There are many signs that could indicate that your commercial building's flat rooftop is leaking. Water accumulating along the ceiling or dripping onto the top floor of your building could prompt you to delve further into the possibility of a leak.

While inspecting the rooftop, you may take notice of the roofing membrane separating from the other roofing materials. Loose flashing or water accumulation along the roof deck is indicative of a leak.

Schedule A Professional Inspection

A roofing contractor will perform a more extensive inspection than you did. They will determine the location where a leak originated from. They will also determine what may have triggered the damage to the rooftop.

If your building is located in a region that receives direct sunlight or a lot of rain, these variables could have weakened the roofing membrane, the flashing, and other materials that are located along the surface of the rooftop.

Seek A Repair Service

EPM rubber, bitumen, spray polyurethane foam, and felt are materials that are used to construct flat roofing systems. A roofing contractor will dry roofing materials. Failing to perform this step could lead to the weakening of roofing materials that are not already damaged.

A roofing contractor can patch damaged parts of the roof. A patching process will necessitate that the part of the roofing membrane that is damaged is cut away. Cement will be used to patch holes within the roofing system.

If the felt and decking materials that make up the bottom of the roofing system aren't damaged, the contractor will avoid cutting them during the repair process.

Extensive damage may require that all of the layers that comprise part of the rooftop are removed and replaced.

Pursue New Flashing And Membrane Materials

Roof flashing is commonly constructed of galvanized steel. Flashing is used to route water away from the chimney and edge of the rooftop. If any of the flashing materials that comprise the flat roof system are damaged, a contractor will replace them.

New membrane materials will provide protection to all of the layers of a flat roof system. A new membrane will deflect the sun's rays and prevent water from penetrating.
