A newly re-issued guide clarifies how you should go about replacing a translucent conservatory roof with any solid roof systems that have LABC Registered Details certification, and outlines the conditions you’re expected to meet to ensure the structure complies with the Building Regs.
Whilst most existing conservatories will be able to support the increased loads, potential pitfalls include inadequate foundations that could move and cause settlement differences between the conservatory and the existing house, leading to cracks and water leakage; inadequate window/door supports to take the loads.
What building control will look at:
- Building control will inspect the existing conservatory to ensure it can take the additional load of the new roof. If there are no signs of distress then it’s unlikely the new roof will cause a failure of the structure to the conservatory. This should already have been assessed by the surveyor of the company before carrying out any work.
- Building control will also check that the existing door supports contain steel inserts to distribute the roof load down to the floor slab. Again, this should already have been assessed by the surveyor of the company before carrying out any work.
- Signs of distress may mean that the existing foundations aren’t sufficient to carry the additional loads and so additional requirements are likely to be imposed on you.
- Your LABC surveyor will also want to ensure that the new roof and supporting structure fully complies with the Regs and the remainder of the extension should be no worse than before.
