02The honest problem

Roofing bids are decided on U-values, uplift and guarantees.

Commercial roofing tenders are increasingly evaluated against U-value, wind-uplift, BREEAM contribution and long-form guarantee structures — not just the spec name and the install price.

Most roofing subs can deliver the roof. The bid evaluation, though, is now scored by a façade consultant or building services engineer who wants to see U-value calc framing, wind-uplift design, NFRC or SPRA installer competency, and a clear guarantee structure with the manufacturer.

If the bid pack treats roofing as a simple finishes trade, the evaluation drops. If it treats it as a building-envelope engineering decision, the evaluation rises.

03What’s hard about it

The three problems that cost you the appointment.

  1. 01

    U-value & wind-uplift design framing

    Tender evaluations now check U-value calc against the priced build-up and wind-uplift compliance against the building location. A bid pack that frames these properly out-scores one that lists 'Bauder Total Roof' and expects the QS to believe it.

  2. 02

    NFRC / SPRA installer competency

    Membership at company level isn't enough. The bid pack needs named-installer NFRC / SPRA evidence, manufacturer-approved-installer credentials and training records.

  3. 03

    Long-form guarantee structure

    20-year, 25-year or insurance-backed guarantees from the manufacturer are increasingly part of the tender. The bid pack should frame what guarantee you're delivering, what the manufacturer's role is, and how the building owner protects it.

04Sussex market context

Why bid evaluation in Sussex works the way it does.

Sussex sits between the South-East commercial corridor and the South-Coast economic strip. Bid activity is heavier in the Brighton, Crawley, Gatwick Diamond, Worthing and Eastbourne corridors. The mix is commercial fit-out, hospitality refurb, schools and universities, healthcare estates, and a steady stream of council-framework work.

Most Sussex subcontractors win locally on relationships and lose nationally on submissions. The big main contractors running South-East frameworks (Wates, ISG, Willmott Dixon, BAM, Vinci) want the regional sub's site capability — but evaluate the bid pack against the same standard they apply to their tier-1 supply chain. That's where well-priced Sussex firms get out-bid by national rivals with bigger bid teams.

05How it works

From tender on the desk to submission-ready pack.

  1. 01

    You send us the tender

    Brief, scope, return-by date, your draft price.

  2. 02

    We write the proposal pack

    Method statement, programme narrative, commercial roofing-specific compliance evidence, and the supporting documents your evaluator wants to read — in the main contractor's QS language, not yours.

  3. 03

    You review and submit

    Your name on it. Your win.

  4. 04

    You pay only if you win

    £1,500 minimum, 2% of contract value above £75k. Don't win, don't pay.

Founding-team UK firm. Sussex-covering. Karl runs it.

09Frequently asked

Commercial Roofing bid writing — practical answers.

01How much does a no-win-no-fee bid writer cost for a Sussex commercial roofing tender?
£0 if your bid doesn't win. £1,500 minimum if it does, or 2% of contract value on tenders above £75k. There's no upfront fee, no retainer, no hourly rate. The fee is invoiced once you confirm the contract award. Eligible on opportunities over £50k.
02What's included in a commercial roofing proposal pack?
Method statement, U-value and wind-uplift design framing, fall-arrest / safe-working-at-height plan, LPCB / FM Approvals compliance narrative where the tender scores it, NFRC / SPRA installer competency framing, programme narrative tied to weather windows, defect and guarantee structure, and experience matrix mapped to evaluation criteria.
03Do you handle guarantee-backed manufacturer schemes properly?
Yes. If the tender requires a 20 or 25 year manufacturer guarantee, the pack frames the manufacturer's role, the installer's manufacturer-approved status, the survey-and-sign-off protocol, and what the building owner needs to maintain to keep the guarantee live. Generic 'we offer guarantees' lines lose evaluation points.
04How long does a commercial roofing bid pack take to write?
A standard sub-package takes 3–5 working days. Frameworks for distribution-centre or schools work — where the U-value, wind-uplift and guarantee framing is heavier — take 6–10 days. We won't compress that on a tight return.
05Are you tied to any specific roofing manufacturer?
No. We write to whatever system you've priced (Bauder, Sika Sarnafil, IKO, Soprema, Kingspan, Knauf Insulation, Marley Alutec, SPRA-listed single-ply systems). The proposal frames your chosen system's U-value, wind-uplift and guarantee credentials in the main contractor's language.
06Do you understand the Sussex / South-East tender market?
Yes. Sussex is part of our warm geography. We work with the regional supply chains around Gatwick, Brighton, Crawley, Worthing, Eastbourne and Chichester — and the frameworks run out of those corridors (universities, healthcare, schools, council estates). We also cover Surrey and Kent within the same warm region, and we work UK-wide on cold opportunities up to £5m contract value.
