On its surface, the flat roof is a simple structure. But what looks simple is actually a complex system of seams, materials and angles that need to work together to function properly. In the end, flat repair is part science, part art. Identifying the source of the problem and the best way to fix it requires a deep knowledge of construction and geometry. Making sure the problem is resolved in an affordable, dependable way requires experience.
While generally less expensive than pitched roofs, flat roofs don’t last as long—their average lifespan is about 20 years.
Over time, hail, ponding water, the sun’s rays and debris can take their toll on roofs, causing the membranes to crack, tear and seams to pull away from the edges. When this happens, the roof leaks—and it’s time to call a flat repair specialist.
The first and most important step in the process is to find a qualified, experienced roofing company. Attention to detail and a commitment to getting the job done right the first time are critical to flat repair; if the problem is not fixed right the first time, it will quickly return.
Every part of the roof needs to be inspected—starting at the bottom of the structure and working to the top—to identify why your roof is leaking.
- Is the membrane delaminating and sliding?
- Are their cracks or tears on the surface?
- Is the offset correct?
- Is water running off or evaporating properly?
- Are the fasteners properly installed and working?
- Is the flashing properly installed and working correctly, or is it rusting?
- Is the pitch of the roof wrong?
Once the problem—or problems—is identified, it’s important to take a holistic approach to flat repair—and to do so while maintaining the integrity and esthetics of the structure.
