Building Regulations for Roof Replacement
If you replace a significant proportion of your roof covering, it's usually notifiable work — and the certificate at the end is what your buyer's solicitor will want to see.
- Notifiable once a substantial area is replaced
- Thermal upgrade normally expected
- Structure must carry any change of covering
- Ventilation requirements apply
- Certificate issued on completion
- We handle notification as part of the job
When it applies
Replacing a substantial proportion of a roof's covering is generally notifiable building work. Small localised repairs are not. Where you're only doing one slope, whether it triggers the requirement depends on the proportion involved — we assess it at quote stage and tell you which side of the line your job falls, in writing.
What the regulations actually ask for
Three things in practice: that the structure can carry the new covering, that the thermal performance is improved to current standards where reasonably practicable, and that the roof space is adequately ventilated so the construction stays dry. Those requirements are why a proper reroof quote includes membrane type, ventilation provision and any insulation work rather than just tiles and labour.
- ▸Structural adequacy for the covering weight
- ▸Thermal upgrade where practicable
- ▸Ventilation to prevent condensation
The paperwork you should get
At completion you should receive either a competent person scheme certificate or a Building Regulations completion certificate from your local authority, plus the manufacturer product information and our workmanship guarantee. Keep all three with your house documents — missing paperwork is a routine cause of delay when a property is sold.
FAQs
Who notifies the council — me or the roofer?+
We handle it. You shouldn't be chasing a building notice yourself for roofing work you've paid for.
What if my roof can't take extra insulation?+
The requirement is what's reasonably practicable. Where a genuine constraint exists it's documented rather than ignored.
I had a reroof years ago with no paperwork — what now?+
A regularisation application through the local authority is the usual route. We can advise on what's likely to be needed.
