Third-Generation South London Roofing Firm Offers 25-Year Guarantee as Standard, Well Above Industry Norm

Worcester Park, Surrey - August 24th, 2026 — First Rate Roofing Ltd, a third-generation, family-run roofing contractor serving South London, South West London, and Surrey, is offering homeowners a 25-year guarantee as standard on all new roof installations—well above what is commonly offered across the region’s roofing trade.

The company’s new roof guarantee is insurance-backed through its membership of the Confederation of Roofing Contractors (CORC), providing homeowners with protection that extends beyond a standard workmanship guarantee. Roof repairs are also covered for up to 10 years under the same terms.

First Rate Roofing is led by John Quilligan, whose family has worked in the roofing industry across three generations. Based on Park Terrace in Worcester Park, the company provides roof repairs, replacements, inspections, chimney repointing, guttering, and fascia and soffit replacement throughout South London, South West London, and Surrey.

“A lot of the quotes homeowners get are guesses dressed up as certainty,” said Quilligan. “We inspect properly before we recommend anything, often with a drone where the cause of a problem isn’t obvious from the ground, and we back what we do with a guarantee that holds up even if something needed doing again years down the line.”

The insurance-backed nature of the company’s CORC guarantee is designed to provide additional reassurance for homeowners. Rather than relying solely on the roofing contractor’s own workmanship promise, the protection is backed independently, helping give customers greater confidence when making a significant investment in their property.

First Rate Roofing also employs its own uniformed and insured team rather than subcontracting work to third parties. The company is a verified member of both TrustATrader and Checkatrade and currently holds a 4.9 out of 5 rating from more than 36 Google customer reviews.

The company’s focus remains specifically on South London, South West London, and Surrey. Quilligan says this local expertise allows the team to understand the area’s varied housing stock, roofing materials, and local requirements, rather than approaching London as a single, uniform market.

For homeowners considering a new roof, the combination of a professionally installed roof, an established family-run company, and a 25-year insurance-backed guarantee represents significant long-term value. Instead of simply paying for the work itself, customers receive decades of additional protection and reassurance built into the service.

With roof replacement being a substantial investment for most homeowners, having that level of cover as standard can make a considerable difference. The 25-year guarantee means customers can have confidence that their investment is protected well beyond the first few years after installation—without needing to purchase a separate extended warranty.

In an industry where shorter workmanship guarantees can be common, First Rate Roofing’s approach gives homeowners an opportunity to secure long-term protection while working with a local, established roofing company. For those looking for value, durability, and peace of mind from a new roof, the 25-year guarantee offers a compelling package.
