Proper attic ventilation is something many people neglect well until winter arrives and snow begins to fall. Poor ventilation traps heat in the attic ceiling and eventually causes snow to melt a lot faster until it ultimate freezes at the eaves. This leads to the formation of ice dams that prevent melted snow from draining into the gutter and instead force it to leak into the roof space and underlying structure. Fortunately, you can prevent the buildup of ice dams and minimize water damage on walls and ceilings by installing high-performance roof exhaust fans. Along with the proper insulation, roof exhaust fans will keep the hot air out of your attic, as the case should be. In some cases, a roof exhaust fan even helps preserve the condition of the roofing systems, especially roof covering materials like asphalt shingles and wood shakes and shingles. Many roof exhaust fans these days are equipped with electronic thermostats that automatically kick in as soon as changes in attic temperatures are detected. However, roof exhaust fans can be operated manually as well. These fans generally require the same set of installation methods even if they come from different brands or manufacturers. Roof exhaust fans can be installed in two ways. Normally, the exhaust fan can be mounted in the gable end or at the edge of the part where two the points meet to form a triangle, also called the roof pitch. The fan is then set behind louvers to protect it from extreme heat or cold. Alternatively, the exhaust fan can be mounted atop of the roof itself, typically at the topmost ridge. Roof fans come from different brands such as the ever reliable Delhi fans. You certainly can’t go wrong with products from a brand that has maintained a good reputation when it comes to fan and blower technology. Meanwhile, apart from residential roofing applications, a lot of manufacturers also offer exhaust fans for specific commercial applications like restaurant kitchens and offices. Improving indoor air quality is what exhaust fans are all about, but they offer more than that. These fans also help ensure adequate ventilation in attic spaces.
