When tarping a roof it is important that you cover all parts of it including the eaves.
So, What Exactly Are Eaves?
Eaves are basically the part of the roof that overhangs the walls or exterior siding of a building. It can also be defined as the edge of a roof that extends past the outside walls of a house. Eaves consist of two main portions namely: fascia and soffit. Fascia is the board that covers the rafters, running around the building horizontally while soffit is the lining that forms the underside of the eaves.
What’s The Essence of Installing Eaves on a Building?
The main aim of having eaves on the roofing is to protect the siding and the foundation of a structure. Well protruding eaves allow snow and rain to run off the roof, away from the walls, to the ground. Should water be allowed to run down the walls directly, it could cause leaks both between the joins of the roof and the walls. In the worst case scenario, the rain water could even leak into below-ground storeys, which is a recipe for timber rot or
mold growth on the walls.
Apart from shielding rain away from the walls, eaves provide shading to windows which helps maintain the house’s interior temperatures at comfortable levels. During winter, eaves will ensure you get enough sunlight through
the window while in summer, they will provide the much needed shade to protect you from the scorching sun. So eaves are really an important part of the climate control in any house.
Types of Eaves
The eaves of a roof can take on different shapes. But there are three main types of eaves you can adopt:
– A closed eave: It has a very little or no extension beyond the house’s siding
-An open eave: Features a pronounced overhang, which often reveals projecting roof beams and/or brackets
-A box eave: This type of eave is enclosed with a soffit and usually runs horizontally or from end to end
How Eaves Are Designed and Constructed
When doing roofing, it’s important to remember that the width of the eave needs to be proportional to the pitch or slope of the roof. That means a steeper roof pitch will produce a narrower eave and vice versa. The eaves of north facing windows (which hardly need any shading) should be 45 percent of the total height, measured from the bottom of the window up the top of the eave. This form of eave configuration ensures maximum heat is blocked from the house in summer and sufficient amount of warmth gets in through the window during winter.
Tiny Facts about Eaves That You Should Know
Eaves are one of the most important components of a house that define its style or structure. Decorative overhanging eaves point to Italian style of roofing and there are some that feature Spanish influence too. Brackets and corbels are usually incorporated in this type architecture to make homes appear statelier.
Most bungalows and ranch-style homes usually take on deep eaves while the craftsman bungalows tend to go with wide eaves. A-Frame houses, on the other hand, feature eaves reaching the ground level. The Eichler Houses come with exaggerated eaves that have a touch of modernity. So there are countless of eave options that you can choose to adopt for your home.
Where Can Eaves Be Appropriate?
Eaves are particularly a great addition to the roofing structure of houses in Australia. With the almost extreme Australian climates, eaves can really do much to regulate house temperatures. Shaded windows can help keep a
house cool, something that can reduce the need for artificial cooling while improving on energy efficiency too. Those building houses in northern Australia, where climates are warmer, should really consider making eaves parts of the
