Pitched To Flat Roof Conversion

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

Pitched to flat roof conversion.

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. Pitched roofs are usually much heavier than flat roofs so an easy replacement may not always be possible. You can tear off the existing roof remove the trusses and strengthen the joists.

This has to happen whether you re just removing the pitched roof or adding another floor with 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. First find the slope by finding the tangent of the degrees eg.

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. Roof span snow load drainage type of membrane are just a few. 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.

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. There are many instances where a flat to pitched roof conversion is a fairly simple job for someone who knows what they re doing. They last 25 50 years while a flat roof membrane will last about 15 20 years. This system is designed to collect the required design loads and transfer them to the existing structure.

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. There are several ways to convert a flat roof to pitched. Most projects will see a flat roof being turned into a pitched one by using a trussed roof with two angled planes. 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 all sorts of things you have to take into consideration depending on where the building is.
