Insurance Backed
Guarantees
When you commission roofing or building work, your investment should be protected. We offer insurance-backed guarantees on eligible works — giving you protection that goes beyond the standard contractor guarantee.
Quick Answer
An insurance-backed guarantee (IBG) protects roofing and building work even if the contractor stops trading, because it is underwritten by an independent insurer. City Building and Roofing Ltd provide insurance-backed guarantees on eligible installations across London and Surrey — including GRP and EPDM flat roofs and full roof replacements — alongside a written workmanship guarantee on all works.
What Is an Insurance Backed Guarantee?
An insurance-backed guarantee (IBG) is a type of guarantee on construction and roofing work that is underwritten by an independent insurer — not just the contractor who carried out the work.
With a standard contractor guarantee, your protection is only as good as the contractor. If the business closes, changes ownership or ceases to trade, your guarantee typically becomes worthless. An IBG removes this risk: because the guarantee is underwritten by an insurer, it remains valid and enforceable regardless of what happens to us as a company.
For homeowners, landlords and property investors making significant investments in roofing or building works, an IBG provides a meaningful additional layer of protection and genuine peace of mind.

Frequently Asked Questions
What is an insurance-backed guarantee (IBG)?
An insurance-backed guarantee (IBG) is a form of guarantee on construction and roofing work that is underwritten by an independent insurer. This means that even in the unlikely event that the contractor who carried out the work ceases to trade, your guarantee remains valid and enforceable — because it is backed by the insurer, not just the contractor.
Which of your roofing works come with insurance-backed guarantees?
We offer insurance-backed guarantees on eligible roofing installations — including GRP fibreglass flat roofs, EPDM rubber flat roofs, full roof replacements and re-roofing projects. Not all minor repair works qualify for an IBG, but we will always confirm which guarantee applies to your project as part of the written quotation.
How long do your guarantees last?
The duration of the guarantee depends on the system installed. Our GRP fibreglass flat roof system comes with a 25-year manufacturer warranty. Full roof replacements are guaranteed for 10 years as standard. All other works are covered by a written workmanship guarantee. Specific terms will be confirmed in your written quotation.
How do I make a claim under my guarantee?
If you experience a problem covered by your guarantee, contact us in the first instance on 020 7118 0095 or by email. We will arrange an inspection promptly and deal with the issue at no cost to you if it falls within the scope of the guarantee. For IBG claims, we will guide you through the insurer process if required.
Are all your roofing works guaranteed?
Yes — all our roofing works come with a written workmanship guarantee as standard. For eligible installations, we also provide insurance-backed guarantees. We will confirm the specific guarantee terms for your project in writing before work begins.
