Strandek® Guarantee – Built for Bristol’s Weather

At Strandek we don’t offer marketing guarantees. We offer real, long-term protection that has protected hundreds of Bristol homes, commercial buildings, and heritage properties for over 50 years.

Every flat roof replacement or qualifying repair we carry out in Bristol comes with:

  • 20-year Strandek® workmanship and system guarantee on materials and installation
  • 10-year FCA-regulated IWA insurance-backed guarantee for extra peace of mind
  • 30+ year expected lifespan, with many Bristol projects still performing after a confirmed 35+ year period

These guarantees are backed by our decades of maritime-inspired craftsmanship and a proven track record of zero major claims on our insurance-backed cover in more than ten years.

The 20-Year Workmanship & System Guarantee

When we install a new flat roof in Bristol we stand behind every detail for a full 20 years.

This covers:

  • Workmanship and installation quality 
  • The roofing system itself (e.g., fibreglass GRP) and associated features such as membrane, insulation, drainage details, flashings 
  • Any defects that arise under normal use and Bristol weather conditions 

Our 20-year guarantee applies to both domestic and commercial projects across all Bristol postcodes and surrounding towns.

FCA-Regulated IWA Insurance-Backed Guarantee

For additional protection we include a 10-year insurance-backed guarantee that is fully regulated by the Financial Conduct Authority (FCA) and underwritten by IWA.

What this actually means for you:

  • Independent third-party backing — not just our word 
  • Protection even if Strandek were no longer trading 
  • Clear claims process with a reputable insurer 
  • Extra reassurance for mortgage lenders, landlords, and managing agents 

This level of regulated insurance backing is one of the strongest available from any flat roofing company in Bristol and the South West.

Proven Performance in Bristol’s Climate

Bristol’s high rainfall, wind-driven rain, and mild but damp conditions put real pressure on flat roofs. That’s why we only install systems we know will last.

Our guarantees are not theoretical. They are backed by:

  • Over 35 years of proven performance on actual Bristol refurbishment projects 
  • Installations from the 1980s and 1990s that are still watertight today 
  • Careful specification of drainage, insulation, and membrane systems suited to local weather 

We have delivered successful projects for local housing teams, private landlords in Clifton and Redland, commercial property managers at Harbourside and Temple Quay, schools, and high-end waterfront developments. Many of these clients return to us because our guarantees deliver real, long-term results.

What Our Guarantees Mean for Bristol Homeowners & Businesses

  • Homeowners — Protection for your biggest investment and peace of mind for your family 
  • Landlords & managing agents — Strong documentation for tenants, lenders, and future sales 
  • Commercial & heritage properties — Reliable cover that respects listed buildings and conservation areas 
  • Architects & surveyors — A guarantee package they can confidently specify 

We have never had a single claim on our insurance-backed guarantee in over a decade. That record comes from doing the job properly the first time.

Frequently Asked Questions About Our Guarantees

How long is the guarantee on flat roof work in Bristol?
We provide a full 20-year workmanship and system guarantee on every replacement and qualifying repair, plus a separate 10-year FCA-regulated IWA insurance-backed guarantee.

Is the insurance backing really FCA regulated?
Yes. Our 10-year insurance-backed guarantee is fully regulated by the Financial Conduct Authority and underwritten by IWA — genuine third-party protection.

What happens if there is a problem after 10 years?
Our own 20-year workmanship guarantee continues to apply. The insurance-backed element provides extra security for the first 10 years.

Will the guarantee transfer if I sell my property?
In most cases yes. Our guarantees are designed to be transferable to new owners, which is very helpful for sales and mortgage purposes.
