WEB EXCLUSIVE: Proactive Maintenance for Low-Slope Roofs
- Proper drainage – Debris from wind and storms can clog drains and gutters. Drains should be checked and cleaned every six months to one year to ensure proper flow of water.
- Ponding water – Older roof systems, and sometimes systems where insulation was not installed correctly, have the propensity to pond water. Ponding can occur anywhere on the roof deck, stressing the roof and causing premature failure of most membranes.
- Flashings – Identify roof membrane problems at vertical surfaces including walls and curbs. Look for holes in the membrane, open laps, hail damage, or membrane slippage.
- Penetrations – Inspect condition of roof at locations where vent pipes, soil pipes, heater flues, electric conduits, or gas lines pass through the roof. These penetrations and pitch pans are often the first areas to fail on a roof, but their lifespan can be extended indefinitely through proper maintenance.
- Walk pads – Facility managers should request that any individuals accessing the roof use these pads while performing maintenance or repair services to equipment on the roof.
