The problem of attic air flow and the amount of ventilation essential is controversial. Based on the study performed to date, the best incidence for ventilating asphalt shingle rooftop encountering the outside air in cold climate or where snow accumulation takes place on roofing for extended duration. Under these conditions, ventilation becomes the best strategy for getting rid of excess dampness from attics, therefore stopping condensation that can harm rooftops while preventing ice formation.


What is this attic ventilation?

It is the system that allows air to flow and limits the quantity of moisture. The most efficient ventilation is under the roof set up, and can provide advantages during the entire year.


Why it is important?

The balanced attic air flow system which consists of soffits, eaves, or fascia’s from the roof, as well as exhausts near the roof ridge, serves two main functions. First, it allows fresh air to get into your attic. Second, it enables damp and hot air to escape.


Impact of improper ventilation is that it may increase power consumption for cooling. The warm attic during summer time will make the temperature to rise within your home – which homeowners will battle by starting the air conditioning system to help keep the living area comfortable. To tackle this additional heat, these products and appliances will have to perform hard during extreme conditions, which cause the spike in expenses during summer.


What happens to your attic that has no vent system during summer time? Incorrect air flow can lead to major issues and costly repairs. In the summertime, badly or low-ventilated attic room could get very warm. When combined with dampness, this heat can cause significant damage to shingles, causing them to curl, deteriorate and buckle.



What are the different options for home ventilation?

Installing vents, which are suited for your home as well as environment, will reduce the risk due to dampness and temperature problems. High quality air vents are most common and therefore are effective for using. They are installed without any obstructions or insulation for air to maneuver freely. They are generally developed to keep bugs as well as other unwanted pests out of your home or commercial place. These air vents permit air to go out of your attic and therefore are installed around the roofing, usually on the higher ridge. You will also have to find out how many vents your roof needs.


How can you Enhance Your Attic Ventilation

The U.S. Federal Housing Administration suggests the minimum of one sq. ft. of attic ventilation (split uniformly) for each 300 sq. feet of attic floor area. This 1/300 principle is the standard and will not affect all structures. It is usually the least suggested standard that should be utilized for ventilating attics. But ensure that you do not over-ventilate, because too much of ventilation could also create problem. Excess roof ventilation may cause leakages as well as other issues during intense climate.
