Stop Roof Leaks Before They Disrupt Your Business
5-Year Guaranteed Commercial Flat Roof Protection With Fixed Annual Costs
Most businesses never budget for the roof — out of sight, out of mind. We extend the life of your existing roof, giving you protection, cost certainty, and the time to plan for a replacement on your terms.
Is This Your Roof?
Roof Shield™ was specifically designed for buildings where the original protection has broken down. If any of these apply, this programme is built for you.
Your Warranty Has Lapsed
The original guarantee has expired — or it was only 10–15 years and your roof is still going. You've got no cover, no scheduled maintenance, and no plan for when the next leak hits.
Your Contractor Has Gone Bust
The company that installed your roof no longer exists. Their warranty is worthless. You're left with a roof you didn't specify, no maintenance history, and nowhere to turn when something fails.
Your Warranty Has Been Voided
Maintenance wasn't carried out to manufacturer requirements. Unauthorised work was done on the roof. The warranty terms were breached — and the manufacturer has walked away from the claim.
Lapsed. Voided. Abandoned.
It happens far more than anyone admits. The roofing contractor who installed your membrane five, ten, fifteen years ago has closed down. The warranty they gave you is meaningless. Or the warranty is technically still in force — but maintenance was never carried out to the manufacturer's requirements, so they'll refuse the claim.
The result is the same: you're sitting on an ageing roof with no protection, no maintenance programme, and no plan for when the next leak hits. Every heavy rain is a gamble. Every board meeting, someone asks about the roof — and no one has a good answer.
This is exactly where Roof Shield™ comes in. We don't need to have installed your roof. We take over the responsibility for it — as it stands today — and give you a structured, costed plan going forward.

What Happens When You Ignore the Roof
Most building managers know the roof needs attention. But when budgets are tight and nothing is visibly leaking, it's easy to push it down the list. Here's what that decision actually costs over the next five years.
Minor signs appear
£800–£2kSmall ponding, lifting seams, cracked sealant. Nothing urgent. Maintenance request gets deferred. Estimated cost to fix now: £800–£2,000.
First leak event
£3k–£8kWater finds its way through a failed detail. Emergency call-out with scaffolding. Interior damage to ceiling tiles and electrics. Disruption to tenants or operations.
Recurring leaks, patch on patch
£8k–£20k+Multiple call-outs per year. Different contractors each time. No one knows the full history. Each repair is reactive, expensive, and short-lived.
Insulation saturated, deck compromised
£25k–£60kWater has been tracking through the insulation for years. Thermal performance has collapsed. The deck is showing signs of corrosion or rot. A patch repair is no longer viable.
Full strip-and-replace
£80k–£250k+The entire roof system needs to come off. New insulation, new membrane, new details. Plus internal damage remediation, business interruption, and reputational cost.
A £3,000–£6,000 annual Roof Shield™ fee could save you £100,000+ in unplanned capital expenditure.
The question isn't whether your roof will cost you money. It's whether you'll spend it proactively — on your terms — or reactively, in a crisis.
Not Ready to Replace the Roof? That's Exactly the Point.
Roof Shield™ is designed for organisations that need protection and cost certainty now — but aren't ready to commit to a major capital replacement. It gives you a structured, costed 5-year plan that minimises risk, eliminates budget surprises, and buys you the time to plan capital expenditure properly.
Year 1: We Get to Know Your Roof
The first year is dedicated to building a complete picture of your roof's condition, vulnerabilities, and behaviour. Through scheduled inspections, reactive call-outs, and detailed reporting, we identify the most at-risk areas — drainage pinch points, failed details, membrane wear, and insulation performance. Every finding is documented and feeds into your risk profile, so by the end of Year 1, you have a clear, evidence-based understanding of exactly what your roof needs.
Years 2–5: Protection, Certainty, and Planning Time
With the risk profile established, we deliver proactive and reactive maintenance that keeps your roof performing — while you plan your next move. Costs are fixed. Response times are guaranteed. And every year, you get updated data to inform capital planning decisions. Whether you're building a business case for the board, saving for a phased replacement, or simply buying time — Roof Shield™ gives you the breathing room to do it on your terms, not the roof's.
“We don't promise your roof won't leak. We promise you'll be ready when it does — and you'll already know what it costs.”
Risks Identified Before They Become Bills
A thorough condition audit maps every vulnerability on your roof — so you know exactly where you stand before you spend a penny.
Repair Costs Built Into Your Annual Fee
No emergency quotes. No inflated call-out charges. Reactive repair costs are pre-assessed and priced into your fixed annual fee based on your roof's risk profile.
Guaranteed Rapid Response
When something happens, we're there fast. Priority response times are built into every plan — proven across live client sites.
Planned Maintenance Reduces Frequency
Scheduled inspections and minor repairs catch issues early — reducing the number and severity of leak events over time.
One Fixed Fee. Complete Transparency.
No hidden fees. No guesswork. One predictable annual cost that's easy to budget and easy to justify to the board.
Full Audit Trail & Compliance
BS 6229, BS 5250 and BS 8000 compliant. Photo-documented reports for insurers, auditors and asset managers.
Without vs. With Roof Shield™
Two buildings. Same age. Same roof system. Completely different outcomes.

What Does One Emergency Call-Out Actually Cost?
£3,000–£8,000
Emergency scaffolding
Per mobilisation — often needed just to access the roof
£2,000–£6,000
Emergency leak repair
Reactive patch by whichever contractor is available
£1,500–£12,000+
Interior damage
Ceiling tiles, electrics, stock damage, business disruption
A single emergency event can easily cost £6,000–£12,000 by the time you've paid for access, the repair, and the internal damage. Two or three events in a year — and you're looking at more than a Roof Shield™ programme would have cost for five years.
Typical Roof Shield™ Annual Fee
£3,000–£6,000
Fixed. Predictable. Everything covered.
That's less than the cost of a single emergency scaffolding mobilisation — and it covers you for the entire year.
Nelson House: 7 Leak Events. Zero Surprise Bills.
Within the first six months of our Roof Shield™ programme at Nelson House, the roof experienced seven separate leak events. Not one of them could have been predicted in advance — and that’s precisely the point.
Because the risks had been assessed upfront and the costs built into the annual fee, every event was handled quickly and efficiently. The client received no emergency invoices, no call-out charges, and no surprises. The system worked exactly as designed.
This is what honest roof protection looks like. Not a promise that leaks won’t happen — but a guarantee that when they do, the response is fast, the cost is already covered, and the process is clear.

How Vanguard Roof Shield™ Works
Book Your Free Roof Condition Assessment
We conduct a BS-standard inspection and deliver a photo-documented report outlining your roof's condition, risks, and vulnerabilities. No pressure. No jargon. Just honest, professional insight.
We Assess the Risk Profile
Based on the audit findings, we map the specific risks on your roof — age, condition, exposure, drainage, detailing — and assess the likelihood and cost of reactive events over the programme period.
We Price the Risks Into a Fixed Annual Fee
The cost of responding to and repairing leak events is built into your annual fee upfront. You know exactly what you're paying — and exactly what's covered. No emergency quotes. No budget surprises.
Choose Your Plan
Select from Silver, Gold, Platinum, or Platinum + HydroWatch™ based on your building's risk profile, response time needs, and monitoring requirements.
Your Protection Begins
Scheduled inspections reduce the frequency of events. When something does happen, we respond fast — at the cost you've already agreed. That's the Roof Shield™ model.
HydroWatch™ — Smart Monitoring Between Visits
Even the best inspection programme only sees your roof a few times a year. HydroWatch™ fills the gaps with wireless Tector sensors that sit inside the roof build-up and report moisture levels in real time — so we know about a problem before it becomes damage.
Wireless Sensors
Tector probes installed within the roof construction monitor moisture continuously — no wires, no disruption.
Real-Time Alerts
Data is transmitted to a cloud dashboard. If moisture levels rise above threshold, both you and our team are alerted instantly.
Early Intervention
We can target repairs to the exact location before water spreads — reducing cost, disruption, and long-term damage.
Audit-Grade Data
Continuous moisture records provide BS-standard evidence for insurers, compliance audits, and asset management reporting.
As an official Tector partner, we supply, install, and manage HydroWatch™ sensors as part of your Roof Shield™ programme. Learn more about HydroWatch™ →

“But What About…”
“We can handle maintenance in-house.”
Most in-house teams are brilliant at keeping the building running — but commercial flat roof systems are specialist. Diagnosing membrane failures, assessing insulation saturation, understanding manufacturer detailing requirements, and maintaining a BS-compliant audit trail all need dedicated roofing expertise. In-house teams rarely have the tools, training, or time to do this properly. Roof Shield™ doesn't replace your facilities team — it gives them specialist backup and a documented programme they can point to.
“We're planning to re-roof in the next couple of years anyway.”
That's exactly who Roof Shield™ is for. A re-roof project takes time — board approval, budgeting, procurement, design. That's 12 to 24 months where your existing roof still needs to perform. Roof Shield™ protects you in that gap. And the condition data we gather during Year 1 actually strengthens your capital bid — you'll have evidence-based reporting that shows the board exactly why the investment is needed and what happens if it's delayed.
“We've got a reactive contractor we call when there's a leak.”
A reactive contractor has no knowledge of your roof's history, no access to previous reports, and no incentive to do anything other than patch the immediate problem. Every call-out starts from scratch — and costs accordingly. With Roof Shield™, we already know your roof. We know where the weak spots are, what's been repaired before, and what's likely to fail next. That means faster diagnosis, better repairs, and lower cost over time.
“What if the roof is beyond saving?”
We'll tell you. The free assessment is exactly that — an honest evaluation. If your roof needs replacing now, we'll say so. But most commercial flat roofs have significant remaining service life that can be extended and managed with the right programme. Roof Shield™ is about maximising that remaining life while you plan the next step — not throwing good money after bad.
What Roof Shield Doesn’t Cover
We believe in complete transparency. Here’s what falls outside the scope of every plan:
Everything else? That’s on us. Your free assessment will confirm exactly what’s covered for your specific roof.
