Ponding Water – Flat Roof Problem

The majority of flat roofs are not “flat.” They have just enough of a pitch or slope to drain water from the roof. When water is obstructed by debris or misdirected by damages in the roof, it will naturally find low points in the roof to pond.

If ponding water is left on the roof, it can cause leaks, moss, and algae growth and result in severe damages to the roofing system.

Ponding Water Solutions – The following are actions you can take to correct and prevent water from ponding on your flat roof:

• Keep the roofing system, and all drains free from debris and stored equipment/supplies
• Inspect your roof frequently and immediately after severe weather
• Maintain a commercial roofing maintenance program
• Immediately call for repairs when you detect a problem with your roof (no matter how insignificant it may appear to be)

Tip: If your roofing system uses downspouts, check the entry at the roof connection and the exit at ground level. Make sure they are free of debris or anything that could block water from exiting the roof.

Debris – Flat Roof Problem

When debris (leaves, branches, dust, pollen, etc.) collect on your commercial flat roof, the damages they cause can grow exponentially if not removed quickly.

Debris can clog drains, create barriers that pond water, scratch or tear your roofing system membrane, hold moisture, and deteriorate the roof beneath.

Debris Solutions – The following actions will help you eliminate debris from accumulating and damaging your commercial roofing system:

• Hire a tree service to prune your trees away from the roof and remove dead or diseased limbs
• Inspect your roof frequently
• Create a roof cleaning (clearing) schedule that occurs between regular maintenance visits
• Avoid storing equipment and/or supplies on your roof

Note: When any equipment maintenance is performed on the roof, inspect the work and surrounding area upon its completion to ensure no tools or parts were left behind or unsecured.

Buckling – Flat Roof Problem

Buckling can occur if your commercial structure settles or shifts. A flat roof’s integrity relies on a continuous membrane, and that membrane will settle and shift with your structure, potentially causing it to buckle. The membrane may also buckle if your commercial flat roof was poorly installed.

Buckling Solutions – Your first line of defense from a buckling roof membrane is early detection. This can be achieved by:

• Maintaining your commercial roofing maintenance program
• Following a frequent inspection schedule
• If you suspect that the building has settled or shifted, you should consult an engineer and have a building inspection performed.
• If you suspect that your roofing system is defective, consult your roofer and hold the installers accountable for their work.

Note: The impact of a tree falling on your building, a vehicle crashing into it, or heavy objects carried by severe weather systems can cause this commercial flat roof problem as well.

Shrinkage – Flat Roof Problem

Also known as “alligatoring,” shrinkage occurs in regions where temperatures fluctuate from extremely cold to extremely hot and cause a flat roof membrane to crack, tear, and literally pull itself apart at its seams.

Shrinkage Solutions – While we cannot control the weather, like buckling, early detection of this problem is how to stop it or slow it down. Increase your roof inspection schedule during:

• Seasons with temperature swings between extreme cold and extreme heat
• Rainy seasons accompanied by hot weather
