Pitched To Flat Roof Conversion

There are many instances where a flat to pitched roof conversion is a fairly simple job for someone who knows what they re doing.

Pitched to flat roof conversion.

They last 25 50 years while a flat roof membrane will last about 15 20 years. There are several ways to convert a flat roof to pitched. 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. 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. There are all sorts of things you have to take into consideration depending on where the building is. You can install a shallow pitched roof over your existing flat roof add a trussed ranch style roof to convert to cathedral walls or even build a new floor and install the pitched roof above that. 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.

First find the slope by finding the tangent of the degrees eg. There are a few ways to dealing with a pitched roof if you choose to convert to a flat roof. Flat roofs are about 10 20 more expensive to install than a pitched roof after the conversion. On houses new pitched roofs typically are supported by the exterior walls as with standard sloped roof construction.

You can tear off the existing roof remove the trusses and strengthen the joists. The slope conversion process is accomplished by installing a light gauge steel sub framing system. There are a couple of different ways to go about a conversion. Pitched roofs have about a 40 longer life than flat roofs.

Roof span snow load drainage type of membrane are just a few. This has to happen whether you re just removing the pitched roof or adding another floor with a flat roof. 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. Add slope to the flat roof.

Realistically speaking to do it right would involve a complete tear off of the roof structure then a re engineering and rebuild of the new flat roof.
