Common Questions About This Flat Roof Soffit Vent 

What is a soffit vent? 

A soffit vent is a roof ventilation system designed for use with a traditional soffit board. When combined with other forms of roof ventilation they help protect your home from damages to belongings, timber and attic insulation caused by temperature changes and moisture build-up.

How many soffit vents should I have? 

The general rule for soffit ventilation is that at least one square foot of ventilation is required for every 150 square feet of attic space. There is an exception that it can be 300 square feet if it is shared between soffit vents and roof vents. Soffit vents should be evenly spaced on both sides of the roof under the edge.  

Why do flat roofs need ventilation? 

Installing ventilation to the flat roof is essential to ensure that hot air can effectively escape from the building without causing damage. This means that the temperature of the roof can remain a similar level to that of outside, significantly reducing the risk of condensation and moisture build-up forming on the inside.  

How do I install the flat roof soffit vent? 

Using the fixing holes provided, the flat roof soffit ventilator should be securely fixed to the soffit board and butted up to the outer brick wall. Depending on the soffit detail, the application process can vary. The vent can also be trimmed to create an insect mesh strip for cottage style or open eaves to suit any rafter centres. To install as a fly screen soffit strip, the soffit vent should be secured to the roof trusses through the pre-drilled fixing holes and butted up to the outer brick wall.

Delivery Information

We understand that ordering products online can be daunting, especially when ordering roofing materials. It is for this reason that we make our delivery processes as simple as possible for you. However, there are a few things to know about our delivery processes. These include:

  • When placing an order, you’ll see a breakdown of your delivery charge in your shopping cart. These charges are for the UK mainland only, and additional charges may apply for Northern Ireland, the Scottish Highlands and other regions.

  • Deliveries only take place on working days (Mon - Fri) and do not take place on Bank Holidays. 

  • You’ll find an estimated delivery on the majority of product pages below the 'Add to Basket' button. Whilst we aim to deliver your items within the estimated delivery, it is only an estimate. 

  • You're able to select a preferred delivery date in your shopping basket. Whilst we aim to deliver your items on this date, it is not guaranteed.
  • Orders placed after 12pm, during the weekend, and on a bank holiday will not be processed until the next working day. Please consider this when placing your order as it may impact your delivery date.

  • After you’ve placed your order, you’ll receive an order confirmation by email outlining the details of your order. Please check your order confirmation email and inform us of any mistakes or errors immediately.

  • Shortly after receiving your order confirmation you’ll receive a separate email confirming the planned delivery date.

  • We can only provide a delivery date and are not able to confirm the time delivery will be attempted. Therefore, we ask that somebody is able to accept and sign for your items throughout the started delivery date.

  • If you are unable to accept and sign for an order, it can be left in a safe location in most circumstances. Please email [email protected] if you would like an item to be left without a signature. 

  • Whilst we aim to hold the majority of our products in stock, due to the vast number of products we offer this is not always possible. Because of this we are required to send your items directly from the manufacturer on a small number of occasions, at which point a different delivery charge may apply as standard.  

  • On occasions the items ordered may be shipped from different depots, which could result in seperate deliveries taking place.

If you have more questions about our products or delivery, please contact our team online or by telephone.
