As we move into spring and the April showers turn into May flowers, one important consideration for home owners is to make sure that rainwater doesn’t create any damage to the building envelope or the foundation. The purpose of the roof drainage system is to collect rainwater from the roof and direct it away from the building foundation by means of gutters, downspouts, leader extensions, splash blocks, or underground drain lines.

An improperly functioning gutter and leader system contributes to water and ice backing up against fascia and under roof shingles and damaged soffits, resulting in possible discolouration or deterioration of siding materials. This can also lead to soil erosion adjacent to buildings and serious water and foundation displacement problems in basements and crawl spaces.

Flooding problems start when the downspout doesn’t empty into a storm sewer or other drainage system designed to carry the water away from the house. Accumulated rainwater can form pools around shrubbery or even cause leaks into the basement. Downspouts should drain at least 6 feet from a house's foundation; however this is sometimes not possible because of a trip hazard or just a lack of space. Another cure is a concrete splash block, or a fibreglass trough.

Leaders that run into the ground normally run into underground drainage pipes that carry the water into a storm sewer or drainage ditch. However, if the underground piping doesn't hook up to a storm sewer system, you could be increasing your chances of basement problems because the water will remain on the property causing flooding.
