The Importance Of Roof Ventilation

The Importance Of Roof Ventilation

Many people have trouble with their heating bills because they don’t realize how vital venting is while running their furnaces or boilers during colder months. Sometimes you may be feeling uncomfortable and stuffy since turning the furnace back on in the winter. Your home may not be getting enough ventilation.

Think of science class when you first learned that heat rises, so gases like air expand as they warm up. If there’s no particular way for those gasses to escape, then they become trapped in places such as the attic. Why is this an issue? You should seek professional aid from an expert roofing contractor to prevent your roof from any damage. 

What Is Roof Ventilation?

Ventilation is imperative to the health of your home and can be a life-saver in many different situations. Proper ventilation helps eliminate old, dry air for new fresh air, which reduces humidity and moisture levels inside your house, keeping you comfortable all year round.

Ventilation works by providing an escape route for hot, humid, or warm moist indoor air that cannot cool down enough outside. It simply accumulates into mold spores or condenses on surfaces such as window panes. Clean air is crucial to your health, yet the average person spends over 95% of their time indoors. Thus, proper ventilation in your home can help you breathe better.

Importance Of Roof Ventilation

Proper ventilation can help you eliminate excess heat and humidity that could otherwise cause trouble in your home. In hot climates, the buildup of this type of air is predictable but may cause different problems for homeowners than it does for those living with cold winters. Both groups could suffer the effects of these two conditions:

  • Need Of Proper Insulation

Exposure to the heat of summer can cause a myriad of problems. When down on your roof, it will get hotter inside and outside in your attic. This excessive heat may damage shingles or warp wood that holds up to itching, leading to leaks and inspections into living spaces like kitchens and bathrooms if they are not adequately insulated from this excess temperature.

In cold climates, warm air escaping from the heated living space below rises to the underside of a roof deck. The bottom layer of accumulated snow on top begins melting, and water runs down towards an edge where it refreezes into ice when faced with extreme temperatures. When this happens repeatedly, an ice dam forms along eaves, blocking any escape for other runoff and backing up under shingles once there is nowhere else left for water to go in your home’s plumbing system.

If you want to be prepared for the winter, your home must be adequately insulated with a self-adhered underlayment. This tear-resistant product seals tight around nails and prevents water from entering exterior walls or your attic where floor insulation can get soaked and drywall below.

  • Cooling Equipment In The House Will Be In Good Condition

Have you ever been in a room that felt humid and then walked into an air-conditioned space? The cold temperature will cause the moisture to condense, leaving your skin feeling refreshed. If this occurs gradually over time, such as when humidity enters through leaks or cracks on your home’s roof system, it can lead to mold growth, putting added strain on cooling equipment within the house!

Signs Of Poor Ventilation

You’ll have to look out for the signs of poor ventilation and then seek aid from a professional. Here, we’ve enlisted some of the signs of inadequate ventilation,


Icicles are a sign of an ice dam, and when you notice large icicles forming along the edges, something is amiss. Icicle formation is when water runs down from melting snow above to freeze at its edge, causing more buildup. This issue can cause significant problems including leaks and worse things like mold growth if not addressed soon enough, so be sure to check those roofs before it gets too hot out for any necessary repairs!

Your Air Conditioner Breaks Down

Many people don’t correlate the condition of their air conditioner with the health of their roof. Still, if you don’t have proper ventilation in place, your HVAC system could overwork itself, and shorten its lifespan. If it has broken down more than once, there’s a good chance that this is due to poor ventilation.

Certain Spots Colder/Hotter Than The Others

If you notice that certain spots are consistently colder than others, then it might be time to call a professional to inspect the roof and your heating and cooling system before they do any more damage.

Unwanted Pests Found Inside

Uninvited guests are more common in the summer. How dreadful that buzzing fly or wasp can be? But what about those creatures and rodents who find their way inside? Maybe it’s time to inspect your roof for any damage so you can take care of the problem as soon as possible before an unwanted guest crawls in through a tiny crack or crevice.

Types Of Vents

There are various types of roof vents that can improve your home’s ventilation. They are:

  • Ridge vents, which release hot air from the ridgeline, may be right for you if you live in an area with extreme heat or cold. 
  • Turbine vents take advantage of wind power and remove humid, stale air when cooling is needed. 
  • Power vents use motors to extract hot, stagnant attic air whenever temperatures rise during the summer months. These work best when combined with thermostats, so they only operate at certain times (for instance, days). 
  • Static vent systems rely on convection currents to exchange warm, moist tropical breezes for cooler, dryer ones without moving parts like blades or turbines – this option works year-round but requires substantial room inside your ceiling space.
