Price ranges by property type and span
Temporary roof pricing is dominated by three things: clear span, hire window, and sheeting type. Here's what we're quoting in 2026 across Essex and Suffolk for fully-engineered, CISRS-built temporary roofs:
| Property / span | Typical cost (8-week hire) | Sheeting |
|---|---|---|
| Bungalow, single hip, 6 m span | £1,800–£2,800 | Reinforced PVC |
| Two-storey semi-detached, 7–8 m | £2,400–£3,800 | Reinforced PVC |
| Two-storey detached, 9–10 m | £3,400–£5,200 | Shrink-wrap or PVC |
| Detached + extension, 10–12 m | £4,800–£7,000 | Shrink-wrap |
| Townhouse / large detached, 12 m+ | £6,500–£12,000 | Shrink-wrap or steel beam |
| Heritage/listed property (any span) | +15–25% premium | Neutral colour required |
What you're actually paying for
A useful temporary roof quote splits the cost into four lines:
- Base scaffold — the working platform the temporary roof sits on. 30–45% of total cost.
- Beam system — aluminium beams (or steel for larger spans), purlins, fixings. 20–30%.
- Sheeting — shrink-wrap or PVC tarpaulin, end gables, ridge cap. 15–25%.
- Hire, inspections and labour — weekly statutory inspections through the hire period. 10–20%.
If a quote is presented as a single round-figure number with no breakdown, ask for it itemised. It's how you compare like-for-like.
What moves the price up
Span beyond 12 m
Aluminium beam systems are economic up to about 12 m clear span. Beyond that you need either intermediate support (which means losing access in the middle of the roof) or steel beam systems (which add £1,500–£4,000 to the quote). Plan the structural sequence around this.
Shrink-wrap vs tarpaulin
Heat-tensioned shrink-wrap is roughly 25–40% more expensive than reinforced tarpaulin. It's worth it for hire windows over 6 weeks, exposed sites, or any heritage job where appearance matters. Tarpaulin is fine for shorter projects in sheltered locations.
Hire extensions
Most quotes assume an 8-week hire window. Extensions sit at £80–£200 per week depending on size. Longer projects should be quoted with a 12 or 16-week hire from the start — it's typically 5–15% cheaper than running short and extending.
Pavement licence and access
Temporary roofs extend beyond the standard scaffold footprint. If the structure sits on or near the public highway, the licence cost typically rises £100–£300 over a standard scaffold, and a wider pedestrian gantry may be needed.
Listed and heritage premiums
Heritage temporary roofs use no through-fixings, neutral-colour sheeting, and protective sleeving on every contact point. A 15–25% premium over the standard rate reflects the additional design and protection work.
What moves it down
- Honest hire window from the start. Don't book 8 weeks if the trade needs 14 — extension rates are higher than baseline.
- Sheltered site. Lower wind loads mean simpler beam designs.
- Vehicle access for the wagon. Reduces hand-balling labour.
- Clear pre-quote spec from the roofer. Beam height, end-gable openings, working area dimensions all locked in before survey.
Real worked example
Three-bed semi in CO9 needing a full re-roof, 7.5 m span, October start, 10-week project:
| Base scaffold (full perimeter, 3 lifts) | £1,150 |
| Aluminium beam temporary roof, 7.5 m span | £950 |
| Reinforced PVC sheeting + end gables | £780 |
| 10-week hire and statutory inspections | £540 |
| Total | £3,420 |
That's representative of an honest 2026 quote on a typical Essex semi. Anyone an order of magnitude cheaper is either uninsured or quoting tarp-on-scaffold rather than a properly designed temporary roof.
Avoiding cost mistakes
- Don't pay for steel-beam systems on a span that suits aluminium. Some firms upsell automatically. Aluminium is correct up to 12 m clear.
- Don't accept a quote without a written design calc. A temporary roof is a structural element; an undocumented design fails insurer scrutiny.
- Don't pay deposits over 25%. Standard is 50% on erect, 50% on strike. Anything above 25% upfront on a job under £8,000 is a red flag.
