Products & Services
New Roof Installation
read moreWe carry out professional new roof installations that are built to provide reliable performance for more than 50 years. Every roof is designed to protect against water ingress, improve energy efficiency by reducing heat loss, and restore your property's appearance. We use carefully chosen roofing materials throughout. Most work is completed within two to five days with a 10-year workmanship guarantee.Roof Repair
read moreWe deliver roof repair services that focus on resolving faults quickly to reduce the risk of further damage. Depending on the condition of your roof, we complete anything from minor tile repairs to larger-scale restoration following storms. We match replacement materials to your existing roof for a neat finish. Our detailed survey allows us to explain exactly what work is needed and why.Roof Inspection
read moreOur roof inspection service focuses on identifying defects at an early stage to reduce the risk of further deterioration. Small issues can quickly develop into more significant structural concerns if left unattended. We examine each roof section thoroughly and classify the results as pass, monitor, or repair. A detailed report with photographs clearly presents the condition of your roof.Roof Replacement
read moreWe provide roof replacement solutions for buildings affected by leaks, deteriorating timbers and roofs at the end of their service life. The roof is fully stripped back to the rafters to allow inspection of the deck. We then reconstruct it with new battens, underlay and tiles. Each project carries a 10-year workmanship guarantee. Our work covers Hampshire.Flat Roof Installation
read moreOur flat roof installation in Hampshire takes account of wet winters, warm summers and coastal salt air. Each system is chosen to match roof size, use and exposure. Options include felt, EPDM, GRP and single-ply systems. We ensure correct falls for drainage with a 10-year workmanship guarantee.Gutter Repair
read moreFaulty guttering poses a clear threat to fascia boards. Timber rot may develop rapidly within months when issues persist. Water passing behind fascia can result in stained render and bubbling plasterwork. We offer gutter repair services across Hampshire, locating faults before repair. Early intervention prevents escalation and helps maintain the integrity of the property structure.Chimney Repair
read moreChimney repair is required when weather exposure causes deterioration to stack components. This impacts mortar joints, lead flashing, brickwork and chimney pot. If not addressed, moisture penetrates structure and causes internal damage. We carry out chimney repair work throughout Hampshire. We undertake site visits, diagnose issues and restore components to durable condition matched to property materials.Wall Cladding Installation
read moreAt C J Roofing & Renewables Ltd, we specialise in wall cladding installation that refreshes property exteriors and strengthens weather protection. A properly constructed rainscreen build-up behind the cladding ensures dependable long-term performance and minimal maintenance. We carefully inspect the existing wall structure and select materials that suit both the substrate and surrounding context. All installations are supported by a 10-year workmanship guarantee for added assurance.Rooftop Solar Installation
read moreRooftop solar installation enables conversion of daylight into electrical energy for homes. A well-designed system can operate for up to 25 years before performance decline becomes apparent. This reduces household electricity costs significantly over time overall savings. C J Roofing & Renewables Ltd provides service across Hampshire integrating panels flashings fixings as coordinated roofing job.Reviews Write a Review

We recently engaged CJ Roofing Ltd to undertake several smaller roofing projects on our behalf, and we have been extremely impressed with the quality of workmanship and professionalism demonstrated throughout.
Connor and his team are highly skilled roofing operatives who consistently delivered work to a high standard, whilst maintaining excellent site safety and organisation. Their attention to detail, reliability, and commitment to quality have made them a valued contractor within our supply chain.
As a result of their performance, we intend to continue working with CJ Roofing Ltd on larger and more complex projects across Central London, including schools, museums, hotels, heritage buildings, and other prestigious contracts.
All operatives are fully trained and hold the relevant industry accreditations and certifications required to work on our specialist projects, giving us complete confidence in their ability to meet the demanding standards expected by our clients.
We would have no hesitation in recommending CJ Roofing Ltd for both commercial and domestic roofing projects and look forward to working with Connor and his team on future contracts.

Had roofing, soffits, and guttering done by C J Roofing & Renewables Ltd and couldnt be happier with the result. Reece, Jay, and Alfie were professional, tidy, and great to deal with. They also did my neighbours roof and they were just as pleased with the work. Highly recommend this team.
