Ventilation
In the same way you breath through your nose and mouth, and a roof breathes through its Intake and Exhaust Ventilation. Your attic is like a big lung, and just like any lung, it constantly requires fresh air circulation or it will suffocate and go bad.
Not having proper ventilation installed for your attic can cause you problems.:
1. Premature shingle deterioration
2. Mould growth in the attic space
3. Paint peeling around the upper perimeter of your house
4. Serious condensation build up during winter time
5. Uncomfortable hot air in the house during summer time
...and as if the above 5 reasons were reason enough to ensure proper attic air ventilation, your shingle manufacturers warrantee can even become null and void if proper Ventilation is not installed. If you are concerned about your roof, or think you require a Calgary Roof Repair, contact us immediately.
The bottom line is, proper ventilation for your attic space is extremely important.
Interesting note: Many roofing companies in Calgary do not know how to calculate whether or not there is sufficient ventilation installed for your attic. For your reference, to calculate the proper amount of ventilation required for your attic, do the following:
a) multiply the total square footage of your attic space by 144
b) now divide by 2
c) now divide by 300
d) your now left with the 'net free' square inch area required for your each your intake ventilation, and your exhaust ventilation
e) you can now divide by this 'net free' square inch area by the 'net free' area provided by a Ventilation Product to determine how many vents your roof needs in order to be properly ventilated
Intake Ventilation is most often found underneath and behind the eaves trough (tiny holes or grills going into the attic, called sofit venting) and Exhaust Ventilation is located at the highest points of the roof. Just as most houses in Calgary are slightly different in style and design, so is the style and design of exhaust vents. The Best Exhaust Vents are installed "hidden" along the ridges of the roof and other exhaust vents (the more common ones) are cut into the side of the roof slopes.
