Building Regs Approval for Roofing Works

[Tonberry]

Is building regs approval needed for re roofing works?

The house in question has a pitched roof but there's also a single storey extension to the property with a flat roof of which approximately 70% has been replaced with new asphalt.

Should building control have been consulted and should the work have a certificate?

Pretty sure you are expected to improve the thermal efficiency when re-roofing so building regs probably does apply to the flat roof.

Sounds like a repair to me, so no.

[Mr Whippy]

Isn't there some percentage of roof that classes as needing BR approval.

Was it 40% or 50%?

In any case, 70% of the flat roof is well over 50% of the flat bit. But I'd assume the rule applies to the total roof area, otherwise this would get very complicated very quickly for properties with a complicated roof.

So I assume it does indeed fall under maintenance/repair rather than renewal.

[Tonberry]

I think the introduction of Part L means that even repairs require you to bring up to standard.

These works were carried out in 2021 so should probably have had a building regs application go in. Either that or the roofer self certifies.

It is 50% of the roof according to this.

The planning portal has misquoted the legislation.

It is 50% of the elements surface area

So for a roof which is made of different elements such as pitched and flat it would be 50% of each different roof.

and the roofer cannot self certify

[Mr Whippy]

So is a house with two pitches, two elements, or one double pitched element?

Element is poorly defined, but better than the other website conveyed it.


Also the proper website says about economic feasibility.

If your roof has indeed failed and needs a repair, do you fix it to decent enough regs, or just not fix it because you can’t afford it to latest spec, and live in a damp rotting house?

Or just do what I suspect many do - repair it to the standard that suits you and your budget and then get on with your life.

Functional and economic feasibility, together with when a lesser standard can be acceptable is defined in greater detail in the Approved Document.

That’s incorrect.
