After your original roof has been taken off and cleared away, it’s time to fit on the new roof under lead flashing whilst ensuring the conservatory and roofing are fully secured to the connecting household.

You also need to be sure that the materials of your new roofing is secure enough to handle all weather elements, from wind to snow to heat.
If you’re buying reputable material and using established contractors, you shouldn’t need to worry about this as the material will have everything you need, however it’s worth asking whether the company is registered to Fenestration Self-Assessment (FENSA). This is a fantastic company which makes sure your conservatory is energy efficient and depending on your circumstance, you may need to have a Fensa certificate to adhere to building regulations.
