What is the roof drainage?
The primary purpose of the roof is to protect the structure from weather. Rain and melting snow can quickly damage the structure if they are allowed to stand and penetrate the building, causing the disintegration and weakening of the structure. The roof drainage system redirects water from the roof to the ground surrounding the structure to protect the structure from moisture damage. In the dry areas of the world, roofs tend to be flat with a small or no drainage system. The roofs tend to have a sharper spacing or slope in the rain areas of the world to allow the rain from leaking from the roof. Some structures have large overhangs or ceilings that store rainwater far enough from the building to prevent damage to the foundation water. If the overhang of the structure is shorter, as in most of the United States (USA) and Europe, then a drainage system can be installed to redirect the flow of water from the roof and into the ground. Sometimes the pipe system will be connected to the drainage system to direct rainwater far enough from the building that TRThe man will not pay.
When installing a roof drainage system, several factors need to be taken into account. The roof slope determines how gravity aims to flow water from the roof. The reasonable drain size prevents water backup and stagnant water on the roof. Depending on the surface area of the roof, more drainage may be installed. The appropriate number of drains usually prevents backed -up water due to overload on one or two drainage, which could lead to possible leaks into the basic structure.
Local building regulations determine the correct installation and location of the roof drainage systems by taking into account various factors. The contraceptive will consider the sign of the lawn, the type of land and whether the building has a basement. To determine the type of drainage system to be installed, it may also consider the amount of precipitation, how long it tends to rain and the speed that the precipitation will collect during the outflow.
Once nai isThe roof drainage system is unstantled, should be checked regularly to prevent the leaves and residues from blocking. In the cold winter climate, the snow can melt unless the attic is insulated. The melting can run under the remaining snow and re -gutter, where the temperature is colder, causing the ice dams to form and block the drain. When the melting water collects against the ice dam, it has nowhere to go and can penetrate the roof, causing leaks.
