Who We Work With

If You Manage or Own Commercial Property, This Is for You

You’re responsible for buildings where a leaking roof doesn’t just cause damage — it causes tenant complaints, insurance claims, compliance failures, and budget blowouts you didn’t plan for.

You’ve probably dealt with roofing contractors who quote without surveying, install whatever system they carry on the van, leave no documentation, and disappear when something goes wrong. Vanguard works differently.

Managing Agents

Overseeing multiple commercial properties and need one reliable roofing partner across your entire portfolio.

Facilities Managers

Responsible for building maintenance and need proactive roof management that prevents costly disruption.

Commercial Landlords

Protecting your investment with proper waterproofing specification, not reactive patch repairs.

Developers

Need waterproofing designed right first time — compliant, warrantied, and built to last.

Our Philosophy

Most Roofs Don't Fail Because They Were Installed Badly. They Fail Because Nobody Maintained Them.

Blocked outlets, cracked sealant, debris build-up, ponding water — these are all fixable problems that become expensive ones when ignored. And yet most commercial roofs get zero scheduled maintenance until something goes wrong.

Vanguard’s approach puts maintenance at the centre of everything we do. Not as an upsell. As the starting point. Because a roof that’s properly maintained costs you less over its lifetime, lasts longer, and doesn’t generate the emergency calls that blow your maintenance budget.

Proactive Over Reactive

You stop paying for emergency callouts and start managing your roof on your terms.

Asset Value Protection

Your building’s waterproofing envelope is maintained to protect its long-term value and insurability.

Expert Specification

You get the right system for your building, not whatever product we happen to stock.

Extended Lifecycle

Your roof lasts longer because it’s correctly specified, properly installed, and regularly maintained.

Our Approach

Design-Led. System-Agnostic. Process-Driven.

Most roofing contractors sell you a product. We give you a solution. Our process starts with your building — its condition, its use, its exposure — and works backwards to the right specification. That means you get a system chosen because it's correct, not because it's convenient.

Rigorous Assessment First

Every project starts with a detailed survey. Core samples, moisture mapping, photographic documentation. You get a clear picture of what’s happening before any work is quoted.

System-Agnostic Design

We’re not tied to one manufacturer or one product. We specify PVC, TPO, liquid applied, hot melt, or built-up felt based on what your building actually needs.

Standards & Compliance Led

Every specification meets British Standards, Building Regulations, CDM, and manufacturer requirements. You get documentation that stands up to scrutiny.

PI-Insured Design

Our designs carry professional indemnity insurance. If we specify it, we stand behind it. You carry less risk.

End-to-End Accountability

One company manages your project from survey to handover. No finger-pointing between subcontractors. One point of contact. One team responsible.

Best Industry Practice

We maintain warranties and documentation for the life of your roof. You get ongoing support, not a contractor who disappears after the final invoice.

Client Feedback

Don’t Take Our Word for It

We manage 40+ commercial properties across the South East. Vanguard surveyed our entire portfolio, gave us a prioritised maintenance plan, and have been managing the programme ever since. The reporting alone saves us hours every quarter.

Portfolio Director

Managing Agent, WGP Maintenance

We’d been patching the same warehouse roof for three years. Vanguard assessed it, specified a full overlay system, and delivered it in two weeks. Fixed price, no extras, full documentation. Exactly what we needed.

Facilities Manager

Facilities Management, Accor Hotels Group

The survey report was the most thorough I’ve seen from any roofing contractor. Core samples, thermal imaging, detailed photos. It gave us everything we needed to make a decision and present to the board.

Case Study

Nelson House — Entrepreneurs Circle HQ

A five-day roof condition survey across seven roofs totalling 1,100 m² — with electronic leak detection, thermal imaging, and a structured five-year maintenance plan.

Full Roof Condition & Maintenance Report — Seven Roofs, One Building

Nelson House at Blythe Valley Park, Solihull, is a £5 million commercial headquarters with Kingspan KS1000XD composite deck and Icopal 1.2 mm TPO single-ply membrane across four flat roofs and three metal roofs. Our five-day on-site survey uncovered long-term moisture entrapment beneath the TPO membrane, previous non-compliant rubber tile overlays that had voided the original warranty, and areas of active water ingress.

We delivered a prioritised five-year planned maintenance programme — from immediate targeted repairs and localised liquid encapsulation through to medium-term core sampling and long-term full system upgrade options — giving the client a clear, costed roadmap to protect their asset.

Commonly Asked Questions

We Believe You Deserve Honest Answers

Most waterproofing companies are vague on pricing, evasive about problems, and reluctant to tell you when a competitor might be a better fit. We think that's a waste of your time. Here's what we'll tell you upfront.

Pricing & Costs

We publish our pricing logic. No guesswork, no “it depends” without explanation. You’ll understand exactly what drives your project cost before you commit.

Problems We Address

Not every roof needs replacing. We’ll tell you if a repair is sufficient, if maintenance will extend its life, or if you genuinely need a full system replacement. We’re not here to oversell.

The People Behind the Specification

Two Founders. 25+ Years of Getting on
Roofs. Still Doing It.

Stephen Day & Paull Newsome

Vanguard Waterproofing was founded by Stephen Day and Paull Newsome — two flat roofing specialists who’ve spent over two decades solving the problems that other contractors leave behind.

We started this business because we kept seeing the same thing: wrong systems specified for the building, corners cut on installation, no documentation, and clients left holding the risk when things went wrong.

We built Vanguard to do it properly. Survey first. Specify correctly. Install to standard. Document everything. Maintain long-term.

Today, our team includes a technical manager, project managers, estimating support, and a directly managed installation workforce. We’re growing, but the technical standards don’t move.
