Pitched To Flat Roof Conversion

They last 25 50 years while a flat roof membrane will last about 15 20 years.

Pitched to flat roof conversion.

There are all sorts of things you have to take into consideration depending on where the building is. 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. This system is designed to collect the required design loads and transfer them to the existing structure. Pitched roofs are usually much heavier than flat roofs so an easy replacement may not always be possible.

Add slope to the flat roof. There are several ways to convert a flat roof to pitched. 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. First find the slope by finding the tangent of the degrees eg.

This is because the membrane is more expensive to manufacture as well as the need for more specialized labor. 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. There are a few ways to dealing with a pitched roof if you choose to convert to a flat roof. There are a couple of different ways to go about a conversion.

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. Roof span snow load drainage type of membrane are just a few. Most projects will see a flat roof being turned into a pitched one by using a trussed roof with two angled planes. Flat roofs are about 10 20 more expensive to install than a pitched roof after the conversion.

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. The slope conversion process is accomplished by installing a light gauge steel sub framing system. There are many instances where a flat to pitched roof conversion is a fairly simple job for someone who knows what they re doing. 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.

You can tear off the existing roof remove the trusses and strengthen the joists.
