An overhang is a protruding roofing structure that goes beyond the walls of the house or building. A roof overhang may also be called as an eave. Materials commonly used are metals like aluminum, vinyl or soffit and fascia, depending on its type. A fixed overhang is basically the sturdiest and requires less maintenance compared to an adjustable overhang, but the latter is more flexible since it can easily be expanded or condensed depending on the sunlight and the weather. Then, there is also a removable overhang which makes it a lot easier to alter the structure’s exteriors.

Overhang

General Uses of Roof or Window Overhang

  • Keep water from walls, doors and windows.

Rains cause damage to the sidings of a structure causing wall paint to wither while also bringing dirt or potential damage to the windows and doors. Without an overhang, water is more prone to enter the building as it either slowly seeps in through the walls or splash into an open window or door. As rainwater reaches the floor and splashes through the sidings, the lower part will start to rot easily. Iron frames are also more likely to rust when exposed to rain water.

  • Control solar gain/penetration and protection from heat.

The southern side of a building is commonly prioritized for an overhang since it receives a large amount of sunlight at daytime. Overhangs can control the amount of heat and sunlight that enters your home or building with the shadow it provides.

  • Serve as a walkway or shed.

A carefully designed overhang can keep owners and visitors dry from the rain or protected from the sun as they enter the building if it a pathway is covered with an overhang. Patios and balconies may also be shaded with an overhang, keeping these places a perfect area to sit in any weather.

Factors to Consider in Building an Overhang

There are also other factors to consider in building the ideal overhang for a specific structure. The size of the roof or window overhang depends on the area’s climate and solar noon. Its angle and length must also be carefully calculated in order for it to provide the needed protection from sunlight and rain. It is very important as well to take into account the zoning ordinances as some will require a specific distance of setback from the front yard.

Constructing an overhang is both an art and a science. It is a must to consult an expert beforehand to make sure that needs are functionally and aesthetically met. After all, an overhang is a very important structure in your home or any building.
