Why Mainland Recommends Attic Ridge Venting:

​

1. Will save you money on your energy bills for the life of the roof

2. Extends the life of your roof

3. Manufactures will void their warranties if not installed

4. They look great, are hurricane and insect/critter proof

 

Poor Attic Ventilation Can Ruin Your Insulation, Destroy Your Shingles, And Raise Your Energy Bills!

​

Why Take Risks?

It is estimated that 9 out of 10 homes in North America do not have proper attic ventilation. Why? Because most people are unaware that attic ventilation can impact the longevity of their entire home and roof!

In the summer, improper ventilation can cause attic heat to build in excess of 160°F. This super-heated air eventually penetrates the ceiling insulation into the living area below. Did you know that inadequate attic ventilation will void all manufacturer warranties!

​

Types of damage that can result include:
Premature aging of your roofing system (“fried” shingles)
Warping, cracking, or breaking down of wood framing
Damage to siding, exterior or interior paint, and wallpaper

 

Higher energy costs
A properly ventilated attic can help reduce the load on your air conditioner by moving the super-heated air out of your attic before it builds up transfers into your property and causes damage.

In the winter, various household appliances, bathtubs, showers, and cooking vapors can contribute to excess moisture build-up. Improperly ventilated attics will allow this moisture to collect and cling to the underside of the roof. The moisture will condense and fall, soaking the attic insulation and reducing its efficiency.

 

Additional structural damage can include:

Roof deck warping and rotting of the wood frame
Mildew growth
Buckling of shingles and felt

Proper Attic Ventilation:

​

Proper attic ventilation systems allow a continual flow of outside air through the attic, protecting the efficiency of the insulation and helping to lower temperatures in the living space.

It consists of a balance between air intake (at your eaves or soffits) and air exhaust (at or near your roof ridge).

The FHA (Federal Housing Administration) recommends a minimum of at least 1 square foot of attic ventilation (both intake and exhaust) for every 300 square feet of attic space. For example, if your attic is 900 square feet, you need a total of 3 square feet of ventilation. This amount should be divided equally between intake and exhaust ventilation (i.e., 1 1/2 feet of each) to insure proper air flow through the attic. To calculate the amount of ventilation you need for your home, follow the example shown below.
