Roof Ventilation – Reduce Your Energy Bill & Protect Your Home

roof ventilation

Z Roofing & Waterproofing installs roof ventilation systems in Miami, Florida and the rest of the county.  Roof ventilation systems protect your home from costly repairs by managing air flow in and out of the house.  When done correctly, it lowers cooling costs, improves the lifespan of shingling, and helps to prevent ice build up in colder months by keeping moisture out and helping dry the attic.

Types of Roof Ventilation

Ridge Vents – Ridge vents are low-profile units installed from one side of the roof to another.  Some have a metal ridge, while others go directly over the shingles. This provides even cooling across the entire rooftop surface.

Power Fans – Roof-mounted power fans are colored to match the shingles and have an adjustable thermostat.  Some are electric and others are solar-powered, so pricing varies.  With high-efficiency motors, this type of fan can remove large quantities or warm, humid air from the attic, covering an area of up to 3,000 square feet.

Wind Turbines – Wind turbines are installed on the top of the roof and draw out hot air with the help of wind-power.  These are cheap to install and don’t take up much space, usually only a few shingles.

Gable Louvers – These static vents can match nearly any style of architecture, using angled slats to protect the attic from exposure to the outside.  Most have limited life-time warranties and are sold at the local hardware store, like Home Depot.  They aid in moisture and insect resistance, and they’re fast and easy to install.

Roof Louvers – Simple, generic rooftop vents that help increase airflow to the attic.  These are the cheapest option.

Do You Need Roof Ventilation?

Here’s how you tell if you need roof ventilation installed:

  1. You don’t see them. If you don’t see any of the vents listed above on your roof, call a local company for an inspection.  The energy and cost savings are too large to ignore.
  2. Your ceiling is warm to the touch.  If your ceiling feels like a frying pan, it’s time to install some vents.  Your shingles are probably frying on top of your home and you need better ventilation to lower your air conditioning bill.
  3. You see ice dams on the roof.  After snow falls on your roof, hot air coming from the inside of the house can melt the snow, allowing it to refreeze again to form ice dams.  Ice dams can be heavy, dangerous to people walking near the house, and create excess moisture that you don’t want on your roof.
  4. You see condensation or frost in the attic. If you see frost or condensation in the attic, especially near the ceiling, poor ventilation is most likely the issue.

With properly installed vents in place, the air temperature in the attic will be more stable, saving you money and preventing costly roof repairs.
