Flat roofs storm more likely.
We will do a quick overview and if you d like to learn more check out our pages detailing each roof type.
Flat roofing is not actually flat.
The slope should be a minimum of 1 in 80 but in practice a minimum slope of 1 to 40 should be used to allow for deflection of the roof and for normal building tolerances.
Sometimes this pressure can build up and if the pressure and stress become excessive it can cause.

Flat roofs that are installed too flat or made of poor quality materials can sag in the middle allowing rainwater to pool.
Systems designed for sloped roofs such as asphalt shingles and concrete or clay tiles are installed by overlapping one row on top of another these systems work cohesively with the pitch of the roof to shed rainwater and snow as it falls from the sky.

If pooling is allowed to linger it s likely to deteriorate the exterior of your roof shortening the lifetime of the flat roof.
Roofs with multiple slopes such as a hip roof 4 slopes perform better under wind forces than gable roofs 2 slopes.
