British Standards for Roofing

 

British Standards for Roofing


Keeping track of British Standards can be difficult. Especially due to the risks that come with a large-scale project like roofing it is vital that the project is safe and legal. If you’re trying to work out which British Standards apply to roofing, we at Insulation Bee have the complete guide for you.
The British Standard for Roofing is there mainly to ensure health and safety procedures are followed. They British Standards also aids in helping to improve preservation of energy sources as well as providing environmental benefits.

 

Installing a roof should always be done by a Certified Installer due to the nature of work and expertise needed to carry out such a project. A certified installer is well versed in the regulations and rules as well as being up to date with regulations. This is highly important due to the fact that you are liable if the standards aren’t met and can be penalised alongside needing to re install the roof.

 

A new roof will be required to:

  • resist weather
  • resist the spread of fire from one property to another
  • be able to support loads (weights)
  • provide resistance to heat loss (insulation)
  • be ventilated to protect from condensation (in most cases)
  • have adequate drainage


There are generally two types of roof construction used:

  • Pitch roof - This is where tiles or slates are used, and a void is usually created underneath.
  • Flat roof - This usually consists of felting which has a slight fall to allow rainwater to drain off.

To enable compliance with the requirements of the Building Regulations to be demonstrated, full details of the new roof will be needed - including materials and their dimensions and performance properties.



Covering

The materials used to cover the roof should be durable and capable of resisting the elements of the weather.  With a pitched roof the type of tile or slate you wish to use will be partly governed by how steep or shallow the slope is.  If the roof is close to a boundary, which is often the case, the roof should also have properties to limit the risk from fire spreading across the boundary.


Ventilation

Not all roofs need to be ventilated. Ventilation is not required to a warm roof system, which is where the insulation is placed above the joists or rafters. Otherwise, ventilation is required, and this is known as a 'cold roof system'.

When ventilating a roof, the air should be able to enter at one end and travel through to the other end where it can exit.

 

Re-roofing

If you are preparing to re-roof less than a quarter of your entire roof space, then the likelihood of needing local authority approval for the job is minimal.

On the other hand, you will need government approval in the following cases:

  1. You are planning an extension
  2. Your roofing project will cover more than 25% of your existing roof
  3. You are making structural alterations to your roof
  4. The performance of the new roof will be significantly different to the existing roof
