Considerations criteria for roof selection

Before starting a project of construction and deciding which house is right for you, it is critical to think about the functional design of a house, we have to think also about topographic condition, estimate cost, climatic condition, appearance and maintenance cost. For this the important part of house we consider is a roof. The roof defines the look of a house more than any other attribute, and the shape of the roof will determine how the roof protects the house from rain, wind, sun and snow.

I have been asking myself what types of the roof is best for the house whether is flat roof or pitched roof. I love this question because it gets at the logic that can be employed to see how a given house design will predict required maintenance and rain water drainage. We are going to see how we can select the type of roof according to different condition. 

Pitched roof are roof which have greater slope while flat roof is the roof of low slope, However All roofs should be sloped to drain. The roof selection between pitched and flat roof depends from different factor as listed below.

Pitched roof are less expensive to install and easy maintenance and also is taking low cost in repairing. This is because shingle systems are easier to install than membrane systems and shingles cost less. And also have good appearance which attracts people for outlook.

Pitched roof is good for water drain its means pitched roof increased drainage capacity. With severe region thunderstorms, it is important to have a roof that is able to handle large amounts of rain. In addition to the increased drainage that pitched roofs offer, they also afford you the opportunity to create more space inside of the house.

 Only negative effect of pitched roof is very expensive due to additional building materials its means construction of pitched roof increase the cost of materials used. Pitched roofs also place more stress on a home’s foundation than flat roofs.

 Generally, flat roofs are cheaper to install at the time of construction than pitched roofs. Additionally, flat roofs are significantly easier to walk on for maintenance and inspections Not only that, they are also of high quality and high performance, making them the cost-effective option. You can do many things with your flat roof.

Flat roofs, on the other hand, are more suitable for complex buildings or structures with various levels. This is because if you install a pitched roof on this kind of building, it would require a more complicated rafter system. Flat roofs are also more ideal for large spans since building rafters to support large spans are not only complex but also expensive and impractical.

Negative effect of Flat roofs have the tendency to retain water on the top of the home or building and stagnant water can damage not only the exterior of the structure but also the furniture and carpet inside once it finds a way to go down.

Finally according to the geographical location and the need of people, you would be wise to consider the relative benefits and drawbacks of various roof lines as you look at houses to buy.
