Finding a roofer in Cardiff
Cardiff has a large market for roofing contractors, ranging from sole traders to regional firms. For significant work โ full re-roofs, structural repairs, large flat roof replacements โ NFRC (National Federation of Roofing Contractors) membership is the strongest quality indicator. TrustMark is an alternative government-endorsed quality scheme.
Cardiff's housing stock is varied: Victorian and Edwardian terraces in Pontcanna, Canton, and Roath; 1930sโ60s semis across the suburbs; and newer builds on the outer ring. Each has different roofing characteristics. Victorian slate roofs are still the dominant type in the inner suburbs, while inter-war properties typically have plain concrete tile, and newer properties use profiled concrete or clay tile.
To find a roofer, ask neighbours who have recently had roofing work done โ personal recommendations in Cardiff are reliable. Check Checkatrade, Rated People, and Google reviews for recent Cardiff-specific feedback. The NFRC contractor search at nfrc.co.uk lists registered members by postcode.
Never commission roofing work without scaffolding. Any contractor working off a ladder only is operating unsafely and will produce a poor-quality result. Scaffolding adds to the job cost but is non-negotiable for any significant roof work.
What to check before hiring
Before agreeing to any work, get answers to these questions:
Is scaffolding included? It should be. If a quote seems low, check whether scaffold has been omitted.
What materials are specified? For a Cardiff slate roof, ask whether the replacement slate is Welsh slate (best), Spanish slate (good), or Chinese slate (cheaper but lower quality). For tile roofs, ask about tile make and grade.
What guarantee is offered? A reputable Cardiff roofer should offer 10+ years on a full re-roof and 5+ years on significant repairs. The guarantee should be backed by a deposit protection scheme.
Is the roofer NFRC registered? Verify at nfrc.co.uk. NFRC members operate a deposit protection scheme meaning your money is protected if the contractor ceases trading.
What happens to the old materials? Skip hire and waste disposal should be included in the quote. Confirm this explicitly.

Common roofing jobs in Cardiff
Nail sickness in Victorian slate roofs โ The original iron nails in Cardiff Victorian slate roofs corrode over time, causing slates to slip progressively. A nail sickness repair (stripping and re-nailing with stainless fixings) can significantly extend roof life where the slates themselves are in good condition.
Flat roof replacement โ Many Cardiff extensions and garages have flat roofs that are now at the end of their service life. GRP fibreglass systems are the most popular modern replacement, offering a 25+ year life and a seamless finish. EPDM rubber is a lower-cost alternative.
Lead valley and flashing replacement โ The lead valleys on Cardiff Victorian and Edwardian roofs typically last 60โ80 years. Failed lead is one of the most common causes of roof leaks.
