What is so important about proper ventilation in helping maintain the integrity, life span and warranties of my residential or commercial roof?
Modern home construction results in better insulated and tighter homes. This saves you money on energy bills, but also makes the need for a well ventilated attic more important. Proper ventilation is much more important than many may think.
As a professional roofing contractor in Northern New Jersey, we run across many instances where the severe weather changes have caused unnecessary damage due to improperly installed, or no ventilation. We can tell you firsthand, stories where a simple one or two hundred dollars on an initial roofing job would have saved the homeowners thousands.
Studies show that 90% of all roofs are under ventilated. Read on for an explanation of how improper ventilation can affect a roof, an attic, and ultimately an entire home.
Simple things like normal household activities can become potential problems in a poorly ventilated building.
All these activities generate moisture that damages insulation, rafters, wood decking, underlayment and shingles if an attic isn’t properly ventilated.
Moisture soaked insulation becomes ineffective, thereby requiring excess energy usage. Condensation on wood leads to rotting and expensive repairs. In some cases, entire roof deck replacement is necessary.
Depending on the type of installation or conditions, we recommend from the following types of roof and soffit ventilation systems:
Roof Fan w/ thermostat (Power Vents)
Electric-powered attic vents use a thermostat control to monitor heat and moisture buildup inside the attic. Once properly connected these vents automatically turn on and off when necessary.
The power vents we install have a low-profile metal dome.
These power vents are unobtrusive when installed on the rear side of your home. We strongly recommend electric powered attic vents because they are one of the most effective ways to extend the life of your entire roof and structural system.
Humidistat (Power vent accessory)
Humidistat (Power vent accessory)With humidistat controls, power attic ventilators monitor heat and humidity levels in summer through winter for year-round attic protection from the damaging effects of moisture and heat buildup.
