A roof is one of the most critical parts of a building envelope. It covers the building towards the top to protect it against weather agents and animals. They insulate the house against harsh weather elements and provide drainage for falling water, Different roofs adopt different roofing designs depending on the purpose of building (whether residential roofing or commercial roofing) and roofing materials available. Generally, a roof consists of two main parts:
a) Support structure: Consists of beams and joists which are made of structurally strong materials.
b) Outer layer: This is the part we mostly see. In most cases roof shingles are mainly used as the outer layer.
The process of constructing a roof is very complex as it involves calculating expected loading on the roof and one should have knowledge of roofing materials and their limiting functionalities. Proffesional Roofing contractors like Lsroofers provide the best roofing services and it is best to consult their services when constructing a roof. The design of a roof involves the use of local building codes.
The loads factored in roof construction include the weight of support structure and roof covering and environmental loads (rain, snow or wind). Generally, the support structure is constructed first. There are different types of support structures for the residential roofing systems. The main ones include beam and truss roofs. In most cases timber is the main material used for the roof construction of support structure in the residential building. As for commercial roofing, steel girders are more commonly used. This is because the roof loading is way higher.
Afterwards, the roof covering is laid upon the support structure. Roofing shingles are mainly used as roof coverings. These elements are rectangular and flat and are laid from the bottom edge of the roof towards the top. The shingles normally are made to overlap the joints below. The main functions of the roof covering are to drain out water. The main types of roof covering are distinguished by the roofing material used. These include:
a) Asphalt shingles: Easy to install and are cheap and long lasting
b) Wood shingles: Not commonly used as they are fire hazards
c) Stone shingles: Expensive to install but are very long lasting and can be recycled in another house.
d) Metal shingles: Easily affordable
e) Fiber cement shingles: Encouraged since it is fire-resistant.
f) Plastic shingles: They are light, non-brittle but are a fire hazard.
Another type of roof is the green roof. This is an environment-friendly element where the roof is partly or fully covered with vegetation and a constant growing element. These are grown over a waterproof membrane. This kind of roofing serves to:
a) Absorb rainwater
b) Insulate the house (allows better heat retaining in cold seasons and reflects and absorb solar energy in hot seasons)
c) They create a habitat for wildlife and provide a natural scenic beauty
However, green roofs are quite expensive to put up and maintain.
