What we do

Whether you're buying a property or concerned about the condition of your roof, we provide thorough roof surveys to identify defects, wear and any repairs that may be needed.

From slipped tiles and storm damage to persistent leaks, we carry out roof repairs that restore your roof's performance while helping to prevent more costly problems.

Well-fitted leadwork helps keep vulnerable parts of a roof watertight, particularly around chimneys, valleys, dormers and roof junctions.

We install, repair and replace flat roofing systems for homes, garages, extensions and commercial buildings, using modern materials designed for long-lasting protection.

Protect your roofline with professionally installed fascias, soffits and bargeboards that improve both appearance and weather resistance.

We repair, replace and install guttering systems that direct rainwater safely away from your property and help prevent damp or structural damage.
Our Process
We believe every successful roofing and building project starts with clear communication and careful planning. From your initial enquiry to the final inspection, our straightforward process ensures quality workmanship, complete transparency, and a hassle-free experience every step of the way.
We begin by discussing your concerns or project requirements and arranging a convenient time to visit your property.
We'll carry out a detailed inspection to assess the condition of the roof or building and identify the work that's required.
You'll receive a straightforward quotation outlining the recommended work with no unnecessary extras.
Our team completes the project using quality materials, proven techniques and careful attention to detail while keeping disruption to a minimum.
Before we finish, we inspect the completed work, tidy the site and make sure everything meets the high standard we expect from our own work.

Every property is different, and that's especially true in London. One day we may be repairing a slate roof on a Victorian terrace in Islington, while the next we're installing new fascias on a semi-detached home in Bromley or carrying out building work on a family property in Barnet.
We work with homeowners, landlords and commercial property owners who want dependable workmanship and honest advice. Before recommending any work, we take the time to inspect the property properly, explain what we've found and discuss the most practical solution.
Whether you need a small repair or a larger building project, we aim to make the process straightforward, keeping you informed from the first visit through to completion.
Choosing the right contractor is about more than finding someone who can complete the work. It's about knowing the job will be carried out professionally, safely and to a high standard.
At RJC Roofing & Building, we take pride in delivering excellent workmanship on every project, no matter the size. We understand the variety of properties found across London and adapt our approach to suit each building rather than treating every job the same.
Our customers appreciate clear communication, reliable appointments and a tidy working environment. We believe in explaining the work in plain English, providing honest recommendations and completing projects with attention to detail that lasts long after we've left site.
