How Do You Do A Flat Roof Step By Step?
A flat roof is a roofing system that features horizontal or nearly horizontal surfaces. This type of roof is most commonly found on commercial and industrial buildings but can also be used on residential properties.
Flat roofs are easy to construct and can be built using various materials, making them a versatile option for many buildings.
There are a few key steps to properly constructing a flat roof. First, you will need to Measure your flat roof size and select the right roofing material size. Second, lay down the folded material (EPDM) in the center of your roof.
Thirdly, spread the material across the width of the top. Fourth, allow the membrane to sit for 30 minutes and fold the fabric to the right half of your roof.
- Measure your flat roof size and select the right roofing material size-
Keep in mind the horizontal dimension of your entire top. Also, measure at the center of the roof since your flat roof will likely be placed on the right half of your house.
Next, select the right roofing material size for your project. Three primary materials are used for flat roofs: EPDM, PVC, and asphalt. Each type has advantages and disadvantages, and you should pick one based on specific needs.
EPDM is most commonly used for commercial buildings because it is robust, flexible, and easy to install. On the other hand, PVC is best suited for residential properties as it can last longer than EPDM and provides excellent insulation value.
Asphalt can be used as an alternative to EPDM and PVC. While it is not as strong as the other two, it can last up to 80 years compared to 20 for EPDM and 15 for PVC.
- Lay down the folded material (EPDM)
When laying out your new flat roof, be sure that the finished dimensions are 1-2 inches shorter than the finished dimensions of your house.
Doing this will result in a finished flat roof covering all of your horizontal surfaces and adding an extra layer of insulation on top of your existing roofing system.
- Spread the material across the width of the roof
Next, spread a grid pattern across the width of your new house. Use wood stakes to mark the location of your lines. You should have three lines, each marked 6′ apart.
- Allow the membrane to sit for 30 minutes
While waiting for the material to set, check and ensure that the membrane is appropriately lined up with the wooden stakes.
Also, make sure that your corners are strong and will not be able to be folded over by wind or weather conditions.
You should also inspect any places where you might want to cut out vents since this will allow cold air from underneath your house to get out and prevent mold from forming in these vents.
- Fold the material to the right half of your roof
Once you are convinced that the membrane is securely in place and can withstand any potential wind or weather conditions, it is time to fold your new flat roof.
The first step is to roll back the EPDM away from the edges of your house and take hold of it. Next, unroll it into a flat pattern and line up with all the stake locations. Then turn over so that the EPDM is facing down and pull it up against the top of your house.
