Pitched Root To Flat Roof Line

Increasing roof line pitch roi 50 54 this project doesn t return a lot of bang for your buck either.

Pitched root to flat roof line.

This has to happen whether you re just removing the pitched roof or adding another floor with a flat roof. Low pitched roofs have the pitch below 4 12 33 3. Flat roofs which aren t perfectly flat require a small slope to allow for water runoff. These roofs have a pitch less than 4 12.

Flat roofs operate with the same basic principle but of course their lower angles mean that gravity isn t quite as effective in shedding water rapidly. The roof line defines the look of a house more than any other attribute and the shape of the roof line will determine how the roof protects the house from rain wind sun and snow. Flat roofs and pitched roofs exist side by side as equal partners. There are a few ways to dealing with a pitched roof if you choose to convert to a flat roof.

Generally these roofs have a pitch from 1 2 12 to 2 12 from 4 2 to 16 7. Although referred to as flat they are generally gently pitched. These are found in traditional buildings in regions with a low precipitation modern materials which are highly impermeable to water make possible the very large low pitch roofs found on large commercial buildings. A common question i get during my home inspections is whether flat roofs are less desirable than sloped roofs.

Pitched roofs have peaks and valleys that direct water downward in very specific directions. You can tear off the existing roof remove the trusses and strengthen the joists. Flat roofs are not perfectly flat in reality they need a small slope for water runoff. Generally such roofs have a pitch ranging from 1 2 12 to 2 12.

These are generally difficult in maintenance as they require special materials to avoid leaks. For slopes less than 9 5 we cannot install roof shingles. It has a slope of 2 3. Flat roof connected to pitch roof a flat roof isn t actually flat.

It appears to be flat but it needs a slope to allow the water to drain from the roof. While it does improve the curb appeal of a home and reduce the risk of damaging leaks and expensive repairs changing the roof pitch just doesn t have the same value as adding usable space such as a bedroom bath bonus room etc.
