Roof Ventilation Services

A healthy roof needs to breathe, especially in Vancouver's rainy climate. Proper ventilation is an essential component of any high-performance residential roofing system, allowing air to flow freely to prevent the damaging effects of trapped moisture like mold and rot. Paragon Roofing provides expert ventilation repair and installation in Vancouver to ensure your home stays dry, healthy, and energy-efficient.

Why Roof Ventilation Matters in Vancouver Homes

Proper ventilation repair and installation in Vancouver is essential for a healthy, long-lasting roof in our damp climate. Without a balanced system, your home is susceptible to a cascade of serious and costly consequences, including issues like:

âś” Structural Roof Damage: Trapped moist air condenses on the underside of your roof deck. This can cause the sheathing, trusses, and rafters to rot, compromising the structural integrity of your entire roof.


âś” Mold and Mildew Growth: A damp, stagnant attic provides the ideal breeding ground for harmful mold and mildew, which can damage building materials and negatively impact your home's indoor air quality.


âś” Higher Energy Bills: In winter, trapped moisture makes your insulation less effective, forcing your heating system to work harder. In summer, an overheated attic radiates heat downwards, making your home hotter and overworking any cooling systems.


âś” Reduced Shingle Lifespan: The combination of intense summer heat and year-round moisture can essentially "cook" your shingles from the inside out, causing them to become brittle and fail years before their warrantied lifespan.

Our Ventilation Services

From installing a new, balanced ventilation system to repairing existing vents, our team provides comprehensive solutions as part of our complete roofing services for strata properties. We ensure your building has the proper airflow required to prevent moisture damage, improve indoor air quality for all residents, and enhance overall energy efficiency.

New Skylight Installation

Our installation process is meticulously planned to ensure a perfect, leak-proof result that enhances your home. We begin with a structural assessment to determine the ideal placement for maximum light and safety. Our expert installers then create the opening and build a custom curb, preparing the roof for our signature multi-layer flashing and waterproofing system that integrates seamlessly with your roof.

We install a variety of ventilation types, including:




  • Ridge Vents (Exhaust)
  • Static Roof Vents (Box Vents)
  • Powered Attic Fans
  • Solar-Powered Vents

Ventilation Repairs

Our repair service starts by diagnosing the cause of the ventilation failure, whether it's a damaged unit or an airflow blockage. We then perform targeted repairs to restore the system's integrity and protect your home from moisture damage.

Our repair services include:


  • Replacing broken, cracked, or missing vent covers.
  • Sealing leaks around existing vent flashing.
  • Clearing blocked soffits, baffles, or exhaust vents.
  • Fixing or replacing malfunctioning powered or solar attic fans.
  • Addressing issues related to attic condensation and moisture.

Roof Types We Ventilate

We can create a custom, balanced ventilation system for all major residential roofing types, ensuring optimal airflow and protection regardless of your home's design. We commonly work with:

Asphalt Shingle Roofs

We create balanced ventilation systems that are perfectly integrated with options for shingle roof installations. By combining discreet soffit vents with a low-profile ridge vent, we ensure optimal airflow without compromising the classic look of your shingle roof.

Wood roofs require exceptional airflow to prevent moisture from getting trapped underneath, which can accelerate rot. We design specialized ventilation solutions when properly installing cedar shakes to ensure the wood can breathe and achieve its maximum natural lifespan.

Proper ventilation is key to preventing condensation from forming on the underside of metal panels. We incorporate high-airflow ridge vents and soffits into our metal roof designs for homes, protecting the roof deck and ensuring the system's energy-efficient properties are maximized.

  • Why is my attic so hot in winter?

    A warm or hot attic in winter is a red flag. It indicates that expensive heated air from your living space is escaping into the attic due to poor insulation. This warm air then gets trapped because of inadequate ventilation, creating a moist environment that can lead to condensation and mold.

  • Do roof vents help prevent mold?

    Yes, absolutely. Mold thrives in warm, damp, and stagnant environments. A proper ventilation system exhausts the warm, moist air that mold needs to grow, keeping your attic dry and healthy.

  • What types of roof vents are best for Vancouver?

    For most homes, a balanced passive system is best. This typically involves soffit vents under the eaves for air intake and a ridge vent along the peak of the roof for exhaust. This combination creates a natural, continuous airflow without requiring electricity.

  • How can I tell if my home has poor ventilation?

    Common signs include thick ice dams forming on your roof edge in winter, peeling or blistering paint on your exterior siding near the roofline, a stuffy or damp feeling in your attic, and visible frost on the nails or wood inside your attic during cold weather.
