How to Measure A Roof Overhang?
A roof overhang is measured from the building out to the end of the fascia board. Common measurements for a house overhang is 12 inches and 16 inches. On a shop or pole barn, the overhang is normally 18 inches.
While you may have thought about what color and materials you want for your roof, most of the homeowner doesn’t think about their actual roof design. Roof overhangs have not even crossed the minds of most people. The roof overhang is an extension of the edges or eaves of the roof. The roof overhang can extend beyond a house’s exterior walls for several inches or a few feet.
Many designers don’t pay much attention to roof overhangs. Roof overhanging has many essential functions: they can protect doors, windows, and exterior siding from rain, shade windows in the circumstances when solar heat gain is not desirable. This can help keep basements and railings from drying out. A house with unsuitable roof overhanging can overheat in the summer, have problems getting water into windows and doors, and have premature rotting.
What to Consider Before Measuring Roof Overhang?
Roof overhangs provide an effective solution to protect doors, entryways, and windows. When designing the roof overhanging, you will need to consider some key features. These features can be how much shade you want for windows and doors, the rain in the area around your house, and the balance between solar heat gain and desired shade.
Here are some of the things to consider before measuring roof overhang.
- If the roof overhangs are not large enough, the only way to protect these windows, doors, and entryways is to recess them in a thick exterior wall or install unique covers and flashings for each door or entrance.
- There may be a situation where overlap does not provide sufficient protection. This situation where the overhang does not provide adequate protection is especially familiar with more modern architectural styles. The emphasis is on producing sleek, curved buildings or square, wide-angle buildings.
- There is also another problem to consider i.e., the wind. The length of the roof overhang must be adequately designed to withstand upward winds. This is especially true in geographic areas where high winds are a common problem.
- In the worst case, all external damage from rain and splashing will lead to the sides’ premature rotting. If you visit suburban neighborhoods with old houses, you can often see examples of exteriors where the panels seem protruding from the house. This is a clear sign that something is wrong with the dimensions of the suspended ceiling structure.
Making a roof overhang is an important way for homeowners to protect their home’s exterior and preserve its value. It can also include some specific architectural features that play an important role in making the overhangs more than just functional parts of a house. The roof overhang must be designed according to the specific condition and requirements of the building. The most straightforward and most influential roofing strategy is to build a roof large enough to provide protection. If roof overhangs are of the wrong size, the house will overheat in summer and be particularly at risk of water entering doors and windows.
