Building a roof is no easy task and should not be taken on lightly. It is usually the smarter choice to hire professionals to do your roofing. The roof of a building is very important as it keeps the elements out, regulates the internal temperature, and keeps water away from the building. There are different types of roofing materials that can be used – tile, terracotta, thatch, etc. – and the decision will depend on your location, weather extremes, and budget.
This is how a roof is built:
1. Hire a contractor
Find a reputable contractor that has experience in building roofs and has clients that give good reviews. He will be able to help you make the decisions about your roof design and materials.
2. Make design and material decisions
You need to decide what type or style of roof you want. There are many different styles including gable roofs, flat roofs, hip and pyramid roofs, and shed roofs. The choice of design and materials will be strongly influenced by the climate of the country where you live. Different roofs have different weather-related benefits.
The materials you choose will depend on the climate, budget, and style of roof. There are many different materials to choose from, but not all roof styles offer good use of all the materials. You can choose wood or metal trusses. You can choose tile, terracotta, sink, thatch, brick, etc. for your shingles or main roof covering.
3. Measure the size and pitch of the roof
This is where the contractor’s work starts. He will measure the size of the roof that needs to be built as well as the pitch that is needed based on location, materials, and climate.
4. Draw up a plan
The contractor draws up a plan and works out a schedule. A lot of the design and planning phase happen on computers these days and offer very accurate measurements, estimates, and time scheduling.
5. Purchase the materials
The building cannot begin before all the materials have been purchased and arrived. Waiting for materials can delay the whole building process.
6. Start building
There are four main phases involved in roofing: framing, sheathing, underlayment installation, and roof cover installation.
7. Install trusses and rafters
The trusses and rafters form the frame of the roof and need to be put in place first. The rest of the materials will be built on and around this framework.
8. Sheath the roof
The sheathing is added onto the trusses and rafters. This is the first layer that protects the inside of the house.
9. Install the drip edge
The drip edge is what allows water to run off the roof and away from the building. It prevents water from getting inside the roof by covering the edges.
10. Install the underlayment
This is the second protection layer of the roof and is usually made of felt. Its main purpose is waterproofing the roof.
11. Install the roof cover
This is the last layer and will be made of your chosen material. This will be the tile, thatch, terracotta, etc. outside of the roof that everyone can see.
When building a roof, there are many dangers and possibilities of causing damage. Because of that, it is best to hire a professional to do your roofing for you.
