Proper roof ventilation is vital to your budget, as well as to the life of your home or business. During the cold season, ventilation keeps a cool roof temperature so that ice dams do not form and crack the shingles. During a hot season, venting is needed to emit hot air from the top of the building, facilitating airflow. Failing to provide proper ventilation reduces a roof’s life expectancy by almost ten years. A professional roofer is knowledgeable about the benefits of installing attic ventilation. Benefits of proper ventilation includes preserving the integrity of your roof and attic, reducing heating and cooling bills, and eliminating health issues like allergies, sinus problems and colds.

No matter what your roof is made of: asphalt, clay, cedar, aluminum – even flat roofs made from weatherproof membranes – ventilation is very important. How do you know if your roof needs increased ventilation? Professional roofers can assess your home or business to see if you need better air flow by way of four distinct methods.

The first process is through ‘natural attic’ ventilation, in which an expert roofing technician can use a combination of insulation and vents to impel the natural flow of outdoor air into the attic. A layer of insulation that is free from gaps can be laid on the attic floor to keep the interior air environment from heat gain or loss. This method is extremely common and very popular, if you’re looking for a straightforward, hassle free way to ventilate your roof, this may be the route for you.

Second up is ‘attic fan’ ventilation. An attic fan brings cool exterior air to cool down your attic while also pushing out the hot air. A certified roofer can tell if your roof and attic are well-sealed, which is integral to making this process work. Innovative fan models are designed with both a thermostat and a humidistat which automatically turns on when it detects a certain temperature or humidity level.

Thirdly, there are ‘venting’ systems. Expert roofers – the craftsmen found at for example – can customize a ventilation system that fits your specific needs and install vents like turbines and ridge vents, soffit eaves vents, and finish it with fascia board, which supports rafters. Both turbines and ridge vents draws out hot and humid air.

Lastly, a ‘skylight’ system allows natural light from the sun onto the roof and into the home for better ventilation. Skylight installation can lower energy bills, it brings sunlight into all parts of the home and it is aesthetically pleasing. A professional roofer can install this system, which will also increase the value of your home or business (not to mention your quality of life). Professional roofers should use quality materials that are conducive to your home and budget. Roofing experts can repair roofing problems and they can install eaves troughs and downspouts to protect your roof, especially flat roofs. Roofing companies should offer 24-hour emergency service, 7 days a week. You should also look for limited warranties on their services covering: labour, materials, tear off, and disposal.
