A roof of a house is often imagined as one with two slopes and a triangular front. Though regular pitch roofs are aesthetically pleasing, they are not exactly the most economically feasible. They cost more and require extensive planning while the construction is time consuming and requires specialized labour. In other words: the greater the surface area of a pitch roof, the greater the cost.

One of the best ways to reduce the surface area of the roof is to reduce the pitch angle and make it as close to the horizontal as possible. This results in a flat roof.

This is one of the most economic roofing methods and can be found widely on commercial buildings. Various materials may be employed to build a flat roof, Asphalt, Bitumen and various polymers are among the most popular. The more unconventional materials include green tops (rooftop gardens), glass and alloy metals. These flat roofing systems are gaining popularity among architects, roofing installer and aspiring home owners alike.

The next method in discussion is slightly more expensive as it involves the entire roof to be built out of solar panels. The economic advantage of this particular type of roofs is not immediately obvious, but in the long run, the power generated by the roof can take off a huge chunk off your electricity bill. The initial design of a solar roof has to take the angle of the sunlight in to account. In tropical areas, the efficiency of the roof increases when the angle of the roof decreases and the sunlight falls in a right angle to the ground. In areas closer to the poles, sunlight tends to fall at an angle thus making pitch roofs and gable roofs more efficient.

The materials which are used as a roof covering act as determinant factors to the cost of the entire roof. Apart from the usual and costly materials such as corrugated asbestos, tiles and timber more economic and advantageous materials are also widely available. PVC corrugated sheets are a lightweight, durable and less expensive alternative to asbestos. These are available in a variety of covers, shapes and sized. Zinc Aluminium sheets and fibre glass are other alternatives which are durable, light weight and donít pile up on the cost.

The selection of a roofing material and a type of roof depends mainly on preference. But with todayís wide range of economically and functionally feasible alternatives everyone can select the roofing method most suitable for them with ease.
