Pitched To Flat Roof Conversion

If you know the angle of the roof in degrees you can find the roof pitch by converting the angle in degrees to a slope then finding the rise by multiplying the slope by 12.

Pitched to flat roof conversion. Roof span snow load drainage type of membrane are just a few. There are many instances where a flat to pitched roof conversion is a fairly simple job for someone who knows what they re doing. Flat roofs are about 10 20 more expensive to install than a pitched roof after the conversion. Most projects will see a flat roof being turned into a pitched one by using a trussed roof with two angled planes.

Pitched roofs are usually much heavier than flat roofs so an easy replacement may not always be possible. If you own a building with a flat roof the first thing your contractor will do is consult a structural engineer to make sure your structure can handle the conversion. This system is designed to collect the required design loads and transfer them to the existing structure. The roof pitching is essentially how steep the roof is going to be they are either going to be flat or pitched in this instance we want to take a look at how this can be changed and improved with the help of a roof pitch chart.

They last 25 50 years while a flat roof membrane will last about 15 20 years. On houses new pitched roofs typically are supported by the exterior walls as with standard sloped roof construction. This is because the membrane is more expensive to manufacture as well as the need for more specialized labor. This has to happen whether you re just removing the pitched roof or adding another floor with a flat roof.

First find the slope by finding the tangent of the degrees eg. You can tear off the existing roof remove the trusses and strengthen the joists. There are a couple of different ways to go about a conversion. There are a few ways to dealing with a pitched roof if you choose to convert to a flat roof.

The typical way is to remove the existing roof and add new framing to the home that create a pitched roof over the old flat roof area. The slope conversion process is accomplished by installing a light gauge steel sub framing system. There are all sorts of things you have to take into consideration depending on where the building is. Add slope to the flat roof.

Pitched roofs have about a 40 longer life than flat roofs.
