Why Your Home Needs Roof Ventilation

The condition or effectiveness of your roof ventilation may not be something on the forefront of your mind, but inadequate ventilation can negatively impact the lifespan of your home's roofing system and the quality of your life.

How Your Roof Ventilation Works

Intake vents running inside and along the soffits (material underneath your eavestrough) and alternatively, exhaust vents higher up at a roof ridge or peak, allow for a continuous and uninterrupted flow of air through your attic. The soffit vents draw cooler outdoor air, while the roof ridge vents exhaust warmer, more humid air which naturally rises to the highest points of your attic.  This constant flow of air regulates temperatures and air quality throughout your attic and home.

The Importance of Sufficient Roof Ventilation

Suitable ventilation mitigates the buildup of excess heat and moisture that is typically damaging for your home. The degree of heat and moisture buildup may vary depending on a hot or cold climate, with seasonal climates potentially at the highest risk.  Here are a few examples why its integral that your roof or attic ventilation is up to date and in working condition:

  • Hotter days tend to increase attic temperatures which in turn warp roof sheathing and prematurely age shingles. Extreme heat can also radiate down to the general living quarters if your attic floor is insufficiently ventilated.

  • Humidity entering an otherwise cold attic condenses into moisture that can damage the roofing system, structural elements or attic insulation. That same moisture in a warm and humid attic will present a host of other issues, such as the proliferation of mold and mildew and added strain to the air conditioning system.

  • Warm air escaping to the underside of roof decks in sub-zero weather can cause the lower layers of snow to melt, run and ultimately create an ice dam at the eavestrough.  Properly installed, self-adhered underlayment prevents ice dams from occurring by waterproofing the eavestroughs and soffits.

Common Indicators of Inadequate Ventilation

Poor or inadequate ventilation systems can present a multitude of issues that are made apparent in different ways. Here are a few tell-tale signs to look out for:

  • Unexplained increase in utility bills, possibly a result of wet attic insulation.

  • Ice dams forming in the winter along the eavestrough or roof edges as a result of improperly installed, self-adhered underlayment.

  • Warped shingles and roofline curvature from insufficiently ventilated attic floors.

  • HVAC systems in need of more frequent servicing, an indicator that its being overworked due to excess heat not being effectively exhausted or ventilated.

  • Rust or corrosion appearing on metal components in your attic such as HVAC systems, electrical boxes, and light fixtures.

  • An emergence or increase in respiratory illness or allergy symptoms which may be a consequence of the spread of fungi spores from mold growth in your attic.
