Has your head been in the gutter lately? A properly installed gutter and downspout system performs a seemingly simple task, collecting water that drains off the roof and directing it away from the home. Quite often, homeowners pay little to no attention to their gutters and downspouts, and the system in turn performs poorly or even fails. Lack of maintenance allows for clogs, leaks, and potentially damage to your home. These issues are more extensive and costly to repair then to prevent with a little maintenance.

Natural ventilation occurs when air enters soffit vents, travels unobstructed along the underside of the roof deck, and exits through a ridge vent, gable vent, and/or hat vent. Mechanical ventilation that is temperature-controlled is also effective at reducing heat buildup inside an unconditioned attic space. Proper natural ventilation can be achieved by following the U.S. Department of Housing and Urban Development (HUD) "Minimum Property Standards" (MPS 403-3):

Gutters and downspouts are an important part of any roof drainage system, used to control rainwater runoff. Gutters and downspouts protect a structure from serious damage, as moisture in the roof, walls and foundation of a building can lead to many problems, including mold and mildew issues. The gutter is the horizontal component designed to collect and channel rainwater away from the roof, directing it to the downspouts. The downspout is the vertical pipe used for carrying the collected rainwater away from the structure. The outlet of the downspout can terminate above or below ground. In above ground terminations, splash blocks are often used to direct rainwater away from the foundation of the building. Many buildings and sites utilize a network of underground piping which connects the downspouts to a city or municipal underground storm system.
