Spring is upon us and that traditionally means unpredictable weather across the country. During this time of year, rain showers tend pop up out of nowhere and dump substantial amounts for rain on an area. According to the United States Geological Survey, 1 inch of rain will produce 27,154 gallons of water for every one acre of land. To put that into perspective, that is equivalent of filling a standard residential bath tub full of water 679 times. With that much water falling with one inch of rain, it is important to make sure your property is prepared.

Below are some tips to help protect your business from heavy rain. These basic preventive maintenance steps will help prevent leaks and ensure roof drainage systems will work properly to protect your business from rain throughout the year.

  • Inspect and clean the roof drainage system. This should be done at least twice a year, ideally during the spring and fall. This includes all gutters, interior drains, and scuppers.
  • Check for water. Check for long‐term standing water in gutters and correct any blockages that may be exist. If there are no blockages but standing water still occurs, ensure the gutter is properly sloped toward to the downspout.
  • Check downspouts. Make sure and inspect downspouts ability to funnel water way from the building and that they do not allow water to accumulate neat the perimeter of the building.
  • Trim Trees. Keep trees trimmed and away from the roof to prevent branches from rubbing against the roof and leaves from accumulation and clogging the drainage system.
  • Remove Debris. Remove loose objects and accumulated debris from the roof that could end up in the drainage system. Also make sure and check under and around all roof mounted equipment, antennas, solar panels, and satellite dishes for debris that could disrupt the drainage system’s water flow or cause ponding.
  • Check gutters for granules. For steep sloped roofs with asphalt shingles and low‐sloped roofs with modified bitumen or built up roofs, remove roof cover granules and pea gravel from gutters as they can accumulate, alter the slope of the gutter and impede the gravitational flow of water.
  • Check air conditioning drains. Ensure that all roof mounted air conditions system drain lines funnel water to a drain.
  • Inspect roof drains. Check for and repair cracks around roof drains.
  • Check the slope of the roof cover system. In the event you have a low sloped roof, ensure the slope of the roof cover system and the insulation boards divert water to internal drains when present or to the edge of the roof.
    Long term standing water is an indication of improper slope.
  • Up‐size gutters. When replacing or purchasing gutters, consider a larger size option to allow for greater flow.

In the event you experience water damage at your property, make sure and utilize an IICRC certified restoration contactor to clean up and dry out your home or building. An experienced contactor will have systems and processes in place to make sure the project goes as smoothly as possible. Until next time my friends, be prepared and stay safe.
