Roof ventilation is an important part of roofing. Proper roof ventilation extends the life of a roof and reduces temperature differential between the roof and the air outside. This roof ventilation allows free flow of air and prevents the entry of water, dust and other pollutants.
Why roof ventilation is important-
Roof ventilation is important because the heat and moisture trapped inside the roof can damage roof system components and personal items located inside the roof. Condensation that forms inside roof can be caused by basic household items like washing machines, dish washers, etc which can cause roof leak. Proper ventilation removes moisture and heat and also reduces condensation.
There are many types of roof ventilators available in the market which comes in a wide variety of size, style and shapes. Some ventilates better than others depending on the roof configuration, attic size, climate, etc.
Advantages of roof ventilation:
Absolute low costs, No maintenance costs & No electricity costs. Maintains hygienic conditions by removing foul smell.It's Leak proof, hence doesn't allow water to enter inside.
Following factors are to be considered while determining ventilation:
 Intake and exhaust ventilation should be installed at an approximate 1:1 ratio.
 The 1/300 rule - 1 square foot of roof ventilation per 300 square feet of roof floor space.
 There should be at least three feet of vertical distance between the intake and exhaust vents.
Hence, proper ventilation is human and environment friendly and is also beneficial for roofs.
