roof ventilation

What is the most important room in your home? For many people it will be the kitchen, for others the family room. But, in terms of regulating the temperature of your house and conserving energy it is your attic. Without proper ventilation temperatures in your attic can reach 150 degree. This can cause problems both to your roof and throughout your home. Lack of ventilation and your roof Whether your roof is made from traditional shingle or is the more versatile TPO roofing, it has the potential of being damaged by unventilated attic spaces. A build up of heat in your attic can increase the deterioration of roof shingle and cause fixtures and sealants to move, warp and even melt. Winter damage can be just as dangerous and costly. Poor ventilation can create a build up of moisture in the attic. This moisture can cause supporting beams to rot or swell. In turn this could cause external movement in your roof. Further problems can be caused if the moisture causes heat to be distributed unevenly across the inside of the roof. Combined with poor insulation this can cause uneven heat on the outside of the roof, leading to an uneven freeze of thaw of snow and ice. As well as causing problems for your roof this could be dangerous for anyone moving around outside your home. Lack of ventilation and the inside of your home The build up of moisture that results from poor ventilation can affect all areas of your home. It can cause or increase the growth of mould and mildew, and affect air quality within your home. Any damage to your roof or internal roof supports can have a dramatic effect on your home and safety. At the extreme end you could experience a partial roof collapse. There is also the potential for water to get in through cracks and to find its way into electrical systems. What is proper ventilation? There are two critical elements to any ventilation system, these are intake and exhaust vents. The intake vents allow fresh air to enter into the attic space and mix with air that is already in there. this helps to regulate the temperature of the air. Exhaust vents allow air and moisture to escape into the atmosphere. This aids in keeping the air inside the attic drier and prevents further build up of moisture. To work effectively the exhaust vents have to be placed higher than the intake vents, ideally at least 3 feet above them. Installing proper ventilation will regulate the temperature and moisture levels in your attic. It will work towards reducing your energy bills and help your insulation to work more effectively. Ventilation will also help to cut your repair bills and ensure that your warranties and insurances remain valid. ersatile TPO Roofing
