Pitched Root To Flat Roof Line

Pitched roofs have peaks and valleys that direct water downward in very specific directions.

Pitched root to flat roof line.

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. Take one look at a pitched roof versus a flat roof and the structural differences are quite obvious. You can tear off the existing roof remove the trusses and strengthen the joists.

Generally such roofs have a pitch ranging from 1 2 12 to 2 12. This has to happen whether you re just removing the pitched roof or adding another floor with a flat roof. 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. These roofs have a pitch less than 4 12.

Although referred to as flat they are generally gently pitched. A common question i get during my home inspections is whether flat roofs are less desirable than sloped roofs.
