Why is it important to ventilate underneath the roof?
Proper ventilation in your attic helps address excess heat and moisture that can otherwise wreak havoc on your home. Heat and moisture buildup in an attic cause predictable but different problems in hot and cold climates; areas with hot summers and cold winters can suffer the effects of both.
What happens when a roof is not properly vented?
They say that poor or non-existent ventilation might cause attic temperatures to rise to 150 degrees or higher in the summer. That can lead to damaged shingles and other roofing materials as well as a buildup of condensation and development of mildew and mold.
Do flat roofs need to breathe?
A warm flat roof usually does not require ventilation. What space do I need to allow for the ventilation? To ensure sufficient ventilation, enough space must be provided to allow for the movement of air, preventing the risk of condensation forming within the roof.
Does a rubber roof need ventilation?
Ventilating a Flat Roof Building regulations state that a ventilation gap of at least 50mm must be in place between the insulation and the underside of the flat roof deck. For both a warm and cold flat roof, a vapour control layer must be installed.
Does a roof need to be vented?
Roof vents prevent damage to your shingles. Without proper roof ventilation, you allow the attic to remain at a high temperature. This can damage and crack your shingles well before they should be showing signs of damage.
How do you vent a roof without soffit?
To ventilate your attic without soffits you can use gable vents, eyebrow vents, a venting drip edge, a shingle-over intake vent, wind turbines, or power vents. All are good alternatives if you cannot install soffit vents; however, a very important factor for good ventilation is good insulation.
What is the best way to vent a roof?
For the best results, place roof ventilation near the roof’s peak and soffit vents in the eaves. Air flows in through the soffit vents and out through the roof vents. Vents come in various styles. We chose rectangular, hooded roofing vents and rectangular soffit vents because they’re easy to install.
Can you have too much ridge vent?
It’s possible to have too much exhaust ventilation, but you cannot have too much intake ventilation. If there is more intake ventilation than the attic’s square footage requires, it’s not problematic because any excess intake converts to “exhaust” on the leeward side of the house.
Should flat roofs be vented?
It’s almost always needed, except for houses that already have warm flat roofs. As for cold flat roofs, which are more common, they need this type of ventilation because they collect higher amounts of condensation during the winter.
What type of vent do I need for a flat roof?
The louvered pop vent is also very common among many homes that have a flat roof. The electrical fans can either bring air into the attic area or fresh air intake hoses or allow heated air to be removed from the attic space.
How do I stop condensation on my flat roof?
There are two forms of flat roof construction which can reduce the risk of condensation forming. Essentially, thermal insulation can either be placed above or below the structural roof deck or waterproofing layer.

Can you put rubber roofing on a flat roof?
If you have a flat roof or a roof that has a pitch of less than 4 in 12, you may find yourself more limited in what it is you can install there. One of the most popular options for installing on this type of roof is rubber roofing.
Why do people call it a rubber roof?
Most people refer to a flat roof as a “rubber roof”. The main reason for such popularity of rubber roofs is the lower initial price tag. However, rubber roofs have many inherent problems.
What’s the average life of a rubber roof?
Rubber roofing, when installed professionally, can last 25 years or more. TPO and EPDM roof systems have similar lifespans of 20 to 25 years. High-quality TPO roofing that is reinforced with fiberglass can last even longer. Modified bitumen roofs last an average of 10 to 12 years, and built-up roofs (BUR) last between 15 and 20 years.
