Most roofers I speak to don’t wake up wanting a planning seminar. Fair enough. Re-roofs, repairs and a lot of like-for-like work never need one. The paperwork only turns up when the job changes the shape of the roof — a dormer, a raised ridge, a mansard, or a loft conversion that needs consent.

When that happens, clients often assume the hold-up will be design or neighbour comments. Sometimes it is. Just as often, the application doesn’t even get that far because the first drawing in the pack is wrong.

That drawing is usually the location plan.

A location plan is the simple one that shows which property you’re talking about in the wider street, typically at 1:1250 or 1:2500, with the site edged in red. Case officers use it to stop guessing. Is this 14 or 16? Does the red line include the access? Are we looking at the right mid-terrace in a row of near-identical roofs?

If you’ve ever had a job pause while someone “sorts the drawings,” you’ve probably already met these:

• Red line drawn tightly around the house instead of the land needed for the works.
• Wrong plot edged on a street of matching roofs and chimneys.
• Location plan says one thing; dormer elevations say another.
• A phone screenshot used instead of a proper scaled plan.

None of that is the roofer’s favourite part of the job. It still lands on your programme. Scaffold dates slip, the weather window moves, and the client hears “planning delay” when what they actually had was a map delay.

Location Plan First

A useful habit on dormer and loft jobs is to settle the red line once, early, then force every later sheet to follow it. Location plan first. Block plan next. Then the roof layout and elevations. If those disagree, the planning portal will find out before the slate does.

It also helps to be straight with clients about permitted development. Plenty of roofing work sits inside it. Plenty doesn’t. A five-minute check at quote stage beats discovering a consent requirement after the old covering is off.

When a job does need consent, a clean location plan is the cheapest clarity you can buy. Planning Maps UK prepares OS-based location, site and block plans for planning permission, which a lot of homeowners and contractors use when they want the mapping done properly without turning the roofing firm into a cartography department.

Good flashing details and a tidy ridge still matter more than any PDF. The point is narrower than that: if planning is in play, don’t let a fuzzy map be the reason a solid roofing job sits idle. Get the location plan right, keep the pack consistent, and put the attention back where it belongs — on the roof.
