Sloped Roof Over Flat Roof

Before choosing flat or sloped roof you should know the advantages and disadvantages of both the roofs.

Sloped roof over flat roof.

A sloped roof is more capable of removing water from the building s exterior and can be an attractive alternative to the flat roof. The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches. A roof with one slope historically attached to a taller wall. Flat roofs and sloped roofs both are used frequently in modern constructions.

A roof that is nearly flat or slightly pitched is called a flat roof or low slope roof no roof should be dead flat because it must have at least a slight slope to drain. When it comes to the disadvantages some property owners are being pestered by leaks. To put it in perspective the angle of this slope would be around 30 degrees. An example for a steep sloped roof is 8 12.

Eventually water penetrates the building. These are generally difficult in maintenance as they require special. Generally these roofs have a pitch from 1 2 12 to 2 12 from 4 2 to 16 7. The use of metal retrofit roofs allows the flat roofed buildings to undergo a transformation into a sloped roof building.

Mono pitched roofs pitched here means a roof plane rather than a slope and implies it is not a flat roof mono pitched roof shed skillion lean to roof 2. We can divide roofs into the following categories. Advantages of flat roofs than sloped roofs. Unlike sloped roofs flat roofs are susceptible to ponding water.

Here are some of the advantages of using flat roofs than sloped roofs listed below. Low slope steep slope terms describe roof slope the slant of a roof. A low slope roof is one that has a slope of less than 3 in 12. These new roofs can be either low sloped less than 2 12 functional roofs or high pitched greater than 2 12 architectural roofs depending on the expectations of the building owner.

The slope on a flat roof is too small to shed water and the shallow slope tends to collect leaves and debris that act like dams. Water that stays on a flat roof after it rains will weaken the material over time. Low pitched roofs have the pitch below 4 12 33 3.
