A fully covered working deck over the building, so a re-roof or a restoration carries on in the dry instead of stopping every time the weather comes in off the Atlantic. Designed to TG20, erected by our own gangs, priced in writing before it starts.
Meet JJ Cornwall Scaffolding A temporary roof is a free-standing weatherproof cover built over a scaffold, carried on aluminium beams and finished with tensioned sheeting or a cassette roof system, so a building can be opened up and worked on in the dry. It spans the whole structure rather than sitting on it, so the existing roof can come off entirely underneath.
You need one whenever the building will be open to the sky for longer than the weather can be trusted: a full re-roof, storm damage, a conversion, or restoration work on a historic building.
In West Cornwall that is most of the year. Covered work carries on. Uncovered work waits for a dry week, and the waiting is the expensive part.
The standard solution for a re-roof. Beams flown across the scaffold, sheeting tensioned over the top, gables closed in. The roof underneath can be stripped completely and the job runs through rain.
The roof plus the elevations wrapped, so the whole building is enclosed. That is what you want for containment, for dust and debris on a busy street, or where the walls are worked too.
Long-duration covers where the structure stays open for months and the fabric underneath cannot get wet, taken as a specialist subcontractor to conservation builders. See our heritage scaffolding page.
Getting a compromised roof enclosed while the repair is designed and programmed.
Crash decks and birdcage scaffolds under a fragile or asbestos-cement roof, and bridging over conservatories rather than bearing on them.
Temporary roofs go up across West Cornwall on winter re-roofs, on storm-damaged properties, on holiday lets working to a handover date before the season, and on restoration jobs that stay open for months.

Read more on GoogleHonestly couldn't recommend JJ Cornwall Scaffolding enough. I’ve used these guys since they first started and have never had a single problem. They tackle everything from awkward little jobs to bigger projects with the same high standard of work. Great prices and a top notch crew. If you need scaffolding, give them a call. A few examples of the work for me.

Read more on GoogleI would highly recommend this company. They were professional, efficient and punctual, even taking the rig down the day after we had finished with it and on a Saturday! Communication with Jordan was easy, much better than other companies that couldn’t be bothered.
Read more on GoogleVery efficient and professional set up. Thoughtful and thorough ... Jordan even adjusted the top access boards to ensure our builder had easier reach to fit the new flue linings for the chimney. We couldn’t recommend him more highly

Your job finishes on time, in winterTrades work through the rain instead of standing down and waiting for a gap in the forecast. A programme that survives December is worth more than the cover costs.
Your building stays dry while it is openNo water into the loft, the ceilings, the plaster or the electrics while the roof is off, which is where the real money gets lost on an uncovered strip.
Your materials go on dryTimber, insulation and underlay are laid in dry conditions.
Your price is fixed in writing firstScope, cover and hire period on paper before anything is built.
What is coming off and how long the trades need underneath.
Span, roof area, beam system, flying height, tie positions and the exposure of the site.
The scaffold, the beams, the sheeting, the hire period and the conditions that would change the price.

West Cornwall takes Atlantic weather before anywhere else in the country does. The Met Office's 1991 to 2020 climate averages put annual rainfall across Cornwall at over 1,000 millimetres, and the wettest stretch runs from October to January, exactly when most re-roofing programmes are trying to finish. Add salt-laden wind on an exposed coastal elevation and an open roof in a Cornish winter is not a scheduling problem, it is a standing-still problem.
A temporary roof is designed around that. The frame is specified for the exposure of the site it stands on, built to TG20 and erected by gangs working to SG4.
Jordan James owns JJ Cornwall Scaffolding and prices every temporary roof himself from the yard in Penzance. Ten years in scaffolding, Advanced Supervisor qualified, with a background on structures where long-duration weather protection is the job, not an extra. Jordan's experience includes the Dawlish rail reconstruction, South Crofty tin mine, Hayle viaduct and Lloyds Bank in Bristol, working as a subcontractor to larger companies.
“People weigh the cost of a temporary roof against the cost of the scaffold. Weigh it against what a fortnight of standing still costs you in December, and it is not close.”Jordan James, JJ Cornwall Scaffolding
The exposed coastal towns are where a cover earns its keep: St Ives, Marazion, Newquay, Perranporth and St Agnes, along with Newlyn, St Just, Hayle, Helston, Truro and Falmouth. Travel time east is quoted honestly.
There is no published rate, because the price follows the span, the area covered, the beam system and how long it stands. You get a written quote before any work starts, setting out:
If the job changes once the cover is up, you get the price in writing before the work happens.

Tell us what is coming off and when you want to start. We will look at the exposure of the site and price the cover properly, in writing.
