Do you need building regs to replace a garage roof?
Replacing a garage roof sounds simple, but many people are surprised to learn that building regulations can apply. The good news is the rules are fairly clear once explained, and a good roofer will handle this for you. Here is what you need to know.
Key takeaways
- Replacing more than 25% of a roof covering can trigger building regs
- The rules focus on insulation and structural safety
- Converting a garage to a room almost always needs approval
- We advise you up front whether your job is affected
The 25% rule
As a general rule, if you replace more than a quarter of a roof covering, building regulations can apply, even on a garage. The regulations are mainly concerned with thermal performance (insulation) and that the structure can safely carry the new covering.
For a small patch repair this usually is not a concern. For a full garage re-roof it may well be, which is why it is worth checking before work starts.
Flat roofs and garages
Many garages have flat roofs, and replacing a flat roof covering in full can bring it within the scope of the regulations, particularly around insulation standards for the deck.
If the garage is attached to the house or you are thinking of converting it into a habitable room, the requirements become more involved and approval is almost always needed.
