Well-designed gutter systems will channel water away from your home, reducing the risk of soil erosion alongside the walls of the building. They also decrease the risk of foundation damage and basement flooding. Properly maintained they can last up 20 or even 30 years.
Unfortunately, if gutters are not properly maintained, they are prone to clogging with leaves and other debris. Neglected, they might begin to tilt or pull away from the facia boards to which they are attached. Inexpensive gutter covers and regular cleaning are the obvious solutions.
In some instances gutters are optional, in others they are mandatory. If you opt for rainwater harvesting, gutters are essential because they redirect the water through downspouts into rain barrels, or into pipes that lead to cisterns and water tanks. The roof drain system must, though, be designed specifically for this use, in compliance with relevant local codes.
Force Field Roofing Gutter Installation and Requirements
Georgia’s minimum standard code for one- and two-family dwellings is based on the International Residential Code 2012 (IRC) which specifies standards and regulations for roof assemblies including roof drainage. It became effective in 2014 when the IRC was adopted by the State of Georgia.
This code states that unless the roof is sloped so that rainwater is able to automatically drain over the edges of the roof, roof drains must be installed at every low point of the roof. The code also specifies that where roof drains are required, secondary “emergency overflow” drains or scuppers must be installed where the perimeter of the roof extends above the roof in a way that could cause the water to become entrapped if there is a buildup in the primary drain.
The installation and sizing of overflow drains must comply with the International Plumbing Code (IPC) which requires horizontal gutters to be sized according to the flow rate of water from the surface of the roof. Gutter dimensions, slope, and capacity are all specified in the IPC.
The IRC also specifies the requirements for asphalt shingles which include a mandatory drip edge flashing at the eaves and gables of all shingle roofs. This effectively prevents damage to insulation, roof rot, and growth of mold. The requirement also applies to reroofing.
Drip edges provide additional support for asphalt shingles at the perimeter of the roof and direct water away from the facia and, where there is a gutter, into the gutter.
