Roof Drainage Systems
A roof drainage system is made up of gutters, downspouts and extensions. The job of this system is to guide rain water and melted snow away from your house, roof and foundation and on into the yard. The drainage system components are most commonly made of aluminum, but can also be made of copper, galvanized steel or plastic.
Your roof drainage system is essential to keeping the inside of your house dry and moisture-free. Without this system of channels and pipes, rain water can collect near your foundation, causing moisture in your basement and damage to the stone or concrete that makes up your home's base. The best drainage systems incorporate a method of moving water several feet away from the house, either by using extensions that connect to your downspouts or by channeling the water underground. (Underground extensions only make sense in climates where the temperature stays above freezing.)
