The roof of your home forms part of the building envelope, and it covers the uppermost part of the building. The building envelope provides you shelter from the environment surrounding your outer home, where the roof would be the first defence against rain, hail, snow, frost, wind and the sun.
There are three design elements present in the construction of a roof:
- The Material; of a roof can be anything that is available, and it will also depend on the type of dwelling, or home it needs to cover. Where this home or dwelling is situated in the world will also indicate what materials can and will be used. Materials may range from, straw and seagrass, banana leaves, laminated glass, aluminium sheeting, copper, pre-cast concrete, ceramic tiles and still so much more.
- The Construction; is determined by the amount of support it might need, for instance, tiles that are quite heavy, will need more support, and if the roof has a pitch or is flat. Banana leaves won’t work on a high pitch and our modern type homes, but, it will do well on a dwelling made of nature’s offerings. Some types of roof need a higher pitch, for example, a thatch roof, and others, like pan tiles, will be unstable on too high a pitch.
A flat roof, with a slight run-off, will do fine where there are little rain falls. Drainpipes also help with the drainage of water which makes the slope of your roof irrelevant.
- The Durability; of a home’s roof can become problematic because it is normally the highest part of your home and not easily accessible. If it is damaged by a storm event or should develop an age-related problem, it might turn out to be a costly affair to do repairs or renewals.
When choosing a home, it would be fortuitous to have the roof inspected before purchase and if you are building your own home, do research to make the right decision for roofing in your area.
