When assessing the ways in which we can approach the construction of a building to ensure it achieves a long lifespan, we tend to think of deep foundations and a robust building fabric, too-often overlooking the importance of roofing products.  

In actuality, roofing ventilation products play a vital role in the health and longevity of a building as well as maintaining its structural integrity. 

This blog will explore how roof ventilation can extend the lifespan of the property and show how Kytun’s roofing products ensure every element of a roof’s structure achieves the required levels of ventilation.

What is roof ventilation? 

Roof ventilation is any system that creates airflow into an attic / loft or roof space. At Kytun, we have developed a full range of roof ventilation products to ensure complete roof ventilation, regardless of your roof type.  

Our wide range of Pitched Roof Ventilation products ensures no part of your roof is overlooked and includes Slate and Tile Roof Ventilators, Vent-pipe Adaptors, Fascia & Soffit Ventilators, continuous rafter roll ventilators and Bird Eaves Comb when using profiled tiles. We also provide the unique One-Fix System, a 3-in-1 eaves ventilation solution which dramatically reduces labour costs.  

Which roofing elements can be ventilated? 

Every element of the roof’s structure holds an opportunity for ventilation. Whether your roof is Slate or Tile, vents can be added directly to the roof covering and are availableto suit differing slate sizes, different tile profiles or in universal format as an off the shelf solution. Push-fit Pipe adaptors are also available which readily convert a roof vent to a roof terminal suitable for use with ensuite / bathroom fans right through to whole house MVHR systems.  

Soffit ventilation products are another way of ensuring your finished project will have sufficient ventilation. A range of continuous, “spring wing” or twist and lock soffit vents can be used to meet your needs. 

At eaves level, Kytun has developed a highly sophisticated One-Fix Eaves Ventilation to provide a 3-in-1 eaves ventilation solution which combines over fascia ventilation continuous eaves protector and Bird Eaves Comb. This provides an easy-to-install solution for roofers and helps homeowners lower build costs due to the significant reduction in labour time this product achieves.

Why is airflow important? 

There are three main benefits to roof ventilation which enhance the longevity of a building: 

  1. Moisture Control 

Moisture control is one of the biggest challenges in any building.  Warm, moist air from inside the home rises and can enter the loft through various routes. These routes are far more numerous in older properties. This moisture vapour laden air can become trapped in the attic space as a result of insufficient roof space ventilation. A build-up of vapour over time will lead to harmful condensation formation which in turn can lead to mould growth, wood rot and permanent degradation of the loft insulation. 

Combined, these issues not only to shorten the life span of the roof but will weaken the structural integrity of other components of the building. 

  1. Temperature Regulation  

Proper roof ventilation systems will help to moderate attic temperatures in  hot  weather.  

In hotter temperatures, heat can escape through roof vents, preventing the attic  from overheating and also reduces heat transfer into the habitable areas resulting in a more comfortable living area for the occupants. This reduces thermal expansion in roofing materials and leaves these materials less prone to cracking over time.  

  1. Preserving Energy Efficiency 

In an uninsulated home, up to 25% of heat loss is experienced through the roof, so roof structures play an integral part in achieving energy efficiency in the home.  Regulating attic temperatures through roof ventilation eases the burden on heating and cooling systems and prevents unnecessary heat loss, therefore reducing heating bills and improving the EPC rating on the home. 

4 signs your home needs additional ventilation 

Signs that a building may be suffering from inadequate ventilation include:  

  • High temperatures in the attic space during hot weather 
  • Mould or mildew forming in the attic on any cold surface during cold periods 
  • Appearance of rust on nails or other metal fixings   
  • Uneven roof temperature (visible through the patterns of snow melting at different rates) 

With retrofit available across the range, it is never too late to address your roofing ventilation, and our experienced team will be happy to guide you to the correct choice of product for your individual roof. Why not contact us today to find out more. 

Roof ventilation is a vital ingredient in achieving comfortable conditions in the home, ensuring energy efficiency in a building and protecting structural integrity – all of which contribute to longevity for the structure. Whether your project is a new build or the renovation of an existing property, roof ventilation should be high on your list of priorities to ensure a building will stand the test of time.
