San Jose Roof & Attic Ventilation - Ridge Venting

Nothing We Do At Certified Roofing Is More Important Than
Removing Heat And Humidity From Your Attic With Properly Installed Roof Ventilation Solutions.

Proper ventilation is a necessary element of a well-built, correctly installed roofing system. It's a crucial part of a healthy and comfortable home or business and it can both extend the lifespan of your roof as well as save you money. Often overlooked or taken for granted, good ventilation (attic vents, roof vents, solar attic fans, etc.) allows the hot air in your attic to escape in the summer and in the winter, it keeps the air cool and moisture-free. Homes and businesses that lack proper roofing ventilation are subject to a number of ailments including:


  • Premature aging of your roofing system (“fried” shingles)
  • Warping, cracking, or breaking down of wood framing
  • Roof deck warping and de-lamination
  • Damage to siding, exterior or interior paint, and wallpaper (all caused by poor venting of moisture)
  • Higher energy costs
  • Streaking, staining, and mildew/mold growth
  • Buckling of shingles and felt
  • Added stress to heating and cooling systems
  • Shortened life span for your roof

If heat and moisture aren't removed from your home by a proper venting system, then serious damage can occur along with higher utility bills! Trapped heat causes your air conditioning to work overtime and eats you alive with higher utility bills. Trapped moisture can mean wet insulation, and wet just doesn't insulation doesn't work when it comes to the health of your roof. Trapped moisture can work itself down into your house and cause paint to crack and peel. It can also steal years of useful service from your roof by creating mildew and rot that damages your home and creates unhealthy conditions. Excessive heat can dry out shingles and rob them of a useful life span.


We've all recently read about serious health problems caused by fungi and molds that grow in the home. These health problems are a direct result of moisture problems caused (in considerable part ) by poor venting. At Certified Roofing, we take ventilation very seriously. If you think an average "low ball" roofing company is going to calculate attic size, compute your CFM (cubic feet per minute) ventilation needs, remove your perimeter plywood, remove the rafter blocks and install intake vents to work with a high performance ridge vent on your roof...pinch yourself because you're probably dreaming!

Our experienced ventilation technicians can install a large variety of quality products to make sure you won't find yourself with problems that result from a poorly ventilated property. These include:

 

Ridge vents are installed at the ridge of the roof, allowing hot air and moisture to escape the home or business property. This is one element of a ventilation system.

 

Electric fans are installed to pump hot air out of the attic cavity. These are available in a variety of shapes, sizes and capabilities.

 

Gable vents and soffit vents are installed to work in conjunction with the ridge vent to move hot air out of the attic and to flow fresh air in.

 

Eyebrow and O’Hagen vents are passive vents that emit an airflow out of the attic, drawing cooler air through other vents in the system to prevent excessive heat and moisture build up in your home.
