It provides structural integrity to your entire building, contributes significantly to thermal efficiency, protects against wind damage, and maintains the value of your property. When roofing problems develop, the consequences extend far beyond the immediate area of damage. Water infiltration promotes timber rot, destroys insulation effectiveness, creates ideal conditions for mould growth, and can ultimately compromise the structural stability of your home.
At JB Contractors, we have spent over fifteen years developing expertise in every aspect of roofing work across Plymouth, Truro, Falmouth, Newquay, and throughout Cornwall. Our team includes specialists in traditional slate roofing, modern tile systems, flat roofing technologies, and expert leadwork. Whatever type of roof covers your property, we have the knowledge, skills, and equipment to maintain, repair, or replace it to the highest standards.
We understand that roofing work represents a significant investment and can cause considerable disruption to your daily life. That understanding shapes our approach to every project. We provide detailed quotations explaining exactly what work is required and what it will cost. We schedule work to minimise inconvenience and maintain clear communication throughout. We treat your property with respect, protecting gardens and access areas, and leaving everything clean and tidy when we finish.
Cornwall's climate presents particular challenges for roofing systems. Atlantic storms bring horizontal rain that tests every joint and seal. Salt-laden air accelerates corrosion of metal components. Extended periods of high humidity promote moss and algae growth that can damage roof coverings over time. Our experience working in these conditions means we specify appropriate materials and installation methods that deliver lasting performance rather than premature failure.
Roofing emergencies do not respect convenient timing. Storm damage at midnight, sudden leaks during important family events, or tiles blown off during gales all require immediate response to prevent further damage to your property. Our 24/7 emergency roofing service operates throughout Plymouth, Saltash, Liskeard, and all of Cornwall. We carry materials for immediate temporary repairs on our vehicles, enabling us to stop water ingress quickly and arrange permanent repairs for the earliest suitable opportunity. When disaster strikes your roof, call us immediately on 07414 228 816.
Learn More About Emergency Repairs →When repairs can no longer adequately address underlying problems, complete roof replacement becomes the most practical and cost-effective solution. Our roof replacement service encompasses the entire process from initial assessment through to final cleanup. We strip the existing covering, thoroughly inspect the underlying structure, repair any damaged timbers, install new underlay and battens, fit your chosen roof covering, and complete all associated leadwork, chimney work, and guttering New Roof Installation. We work with all roofing materials including natural slate, concrete tiles, clay tiles, and specialist materials for listed buildings.
Learn More About Roof Replacement →Many roofing problems do not require complete replacement. Individual slipped or broken tiles, deteriorated pointing along ridges and hips, failed flashings around chimneys and walls, and localised damage can often be repaired quickly and affordably. Our roof repair service addresses specific problems without unnecessary expense, extending the useful life of your existing roof. We serve all areas including Bodmin, St Austell, Camborne, and Redruth.
Learn More About Roof Repairs →Flat roofs on extensions, garages, dormers, and commercial buildings require specialist knowledge and appropriate materials. We install and repair flat roofing systems using EPDM rubber membrane, GRP fibreglass, and high-performance felt. Each material offers specific advantages, and we advise on the most suitable option for your particular application. Our flat roof installations carry comprehensive guarantees and, when properly maintained, provide decades of reliable waterproof performance across Falmouth, Penryn, and beyond.
Learn More About Flat Roofing →Traditional pitched roofs have protected buildings for centuries, and for good reason. The sloping design sheds water naturally, provides excellent ventilation to roof spaces, and creates useful storage or living areas in lofts. We work with all pitched roofing materials including natural Welsh and Spanish slate, traditional clay tiles, modern concrete tiles, and specialist materials for heritage properties. Our craftsmen understand both traditional techniques and modern best practices.
Learn More About Pitched Roofing →Water rarely travels in straight lines through buildings. A leak appearing in one location may originate from a point metres away, having tracked along rafters, across membranes, and through multiple layers before finally becoming visible. Our systematic leak detection approach identifies actual causes rather than treating symptoms. We examine roofs methodically, testing suspected entry points and tracing water paths to locate problems that less thorough investigation might miss.
Learn More About Leak Detection →Chimneys face exceptional exposure to weather, standing proud of the roofline where they receive the full force of wind and rain from every direction. Chimney repairs address deteriorated pointing, failed flashings, damaged pots and cowls, and structural problems. We also apply protective treatments that reduce water absorption and extend intervals between maintenance. Essential service for period properties across Launceston, Bude, and historic towns.
Learn More About Chimney Repairs →Lead remains the premier material for flashings, valleys, and weatherings on pitched roofs. Properly installed leadwork lasts for generations, outliving multiple roof coverings. Our team includes experienced leadworkers who understand this traditional craft and produce work that combines visual appeal with lasting weathertight performance. We fabricate and install lead flashings for chimneys, walls, dormers, and valleys across St Ives, Helston, and all Cornwall.

Most roofers will not put a figure anywhere near their website. We think that is unhelpful. You cannot budget for a roof from a page that tells you nothing, and you should not have to book three appointments to find out whether the work is £500 or £15,000. So here is what the published UK averages say, with the honest caveat that a roof is not a product with a price tag.
| Work | Typical UK cost | Notes |
|---|---|---|
| Full roof replacement, UK average | £8,000 | typical range £4,000 – £19,000 |
| Gable roof replacement | £110 – £260 per m² | around £7,000 – £16,250 for a whole roof |
| Hip roof replacement | £145 – £285 per m² | more cuts and more labour than a gable |
| Roof repairs, concrete tile | £90 – £120 per m² | the cheapest common covering to put right |
| Roof repairs, clay tile | £110 – £160 per m² | brittle with age, so breakages add up |
| Roof repairs, natural slate | £150 – £220 per m² | the usual covering on older Cornish property |
| Ridge tile rebedding | £50 – £70 per metre | a very common repair after a gale |
| Lead flashing renewal | £50 – £70 per metre | stepped flashing to a chimney, £80 – £120 |
| Scaffolding | £700 – £1,300 | hire, erection and removal; unavoidable on most pitched work |
| Stripping the old roof | £1,000 – £2,500 | includes skips and disposal |
| Roofer day rate | £280 – £360 | roughly £35 – £45 an hour |
Where these figures come from. Figures are published UK industry averages from Checkatrade’s cost guides, reviewed August 2026. They are national ranges for guidance only — not a quotation from JB Contractors, and not specific to the South West. Every property differs. The only accurate number is the one on a written quote after we have seen the job.
Difficult access, a third storey, natural slate, a roof with several valleys or hips, chimney work, and any structural timber found rotten once the covering is off.
Straightforward two-storey access, concrete tile, a simple gable roof, and catching a problem while it is still a repair rather than a replacement.
Salt-laden air and driving rain shorten the life of fixings and flashings on this coast. Expect nail sickness on slate roofs earlier than inland averages suggest, and budget for renewing fixings rather than just re-laying slates.
“We had been putting off replacing our roof for years, dreading the disruption and expense. JB Contractors made the entire process surprisingly straightforward. Their quote was detailed and fair, their team were professional and tidy, and the finished roof looks absolutely fantastic. We only wish we had done it sooner.”
