When it comes to commercial roofing, flat roofs offer a few advantages over sloped roofs. Not only are flat roofs easier and cheaper to install, but they are also easy to access and service. Flat roofing also allows for maximum use of interior space and provides a convenient area for the placement of HVAC units. However, flat roofs are not immune to problems, and leaking is one of the primary concerns. Here are four common causes of roof leaks in flat roofs, and when to schedule roofing repair services.

Poor Drainage

Poor drainage is one of the most common causes of roof leaks on flat roofs, simply because it is easier for melted snow and rain to collect on a flat roof than on a sloped roof. If you do not yet have a good drainage system installed, it is imperative to put one in place immediately. If your roof has already suffered damage from poor drainage and you can see signs of sagging or structural weakness, schedule a professional roofing inspection and consultation right away.

Flashing and Membrane Problems

Proper roof maintenance can do much to prevent and detect early signs of flashing and membrane problems. However, if roofs are not installed properly to begin with or if maintenance services are not kept up over time, tears can form in the membranes and flashing. It is recommended that the flashing on flat roofs be monitored and repaired as needed at least every two to three years.

Age of the Roof

No matter how careful you are to follow a strict maintenance plan, all roofs inevitably age and become more susceptible to leaks over time. How quickly your roof degrades and requires replacement depends on a few factors, including the quality of the initial installation, the roofing material and the harshness of the elements in your area.

If you are concerned about signs of leaks in your roof, it is important to hire professional roofing services to inspect the damage. Depending on how old your roof is and its overall condition, simple repairs or full replacement may be recommended.
