RJC Roofing & Building provides professional roofing and general building services across London. We work with homeowners, landlords and property managers who want clear advice, dependable workmanship and a job completed properly. From a small roof repair to a larger renovation project, we approach every property with the same care and attention.

Our work covers a wide range of roofing and building requirements. This includes roof surveys, repairs, new roofs, flat roofing, chimney work, leadwork, guttering, fascias and soffits, emergency roofing and general building projects.
Some customers contact us because they’ve noticed a leak after heavy rain. Others are planning an extension, renovating a tired property or need advice before buying a home. Whatever the reason, we start by looking carefully at the property and understanding what the customer actually needs.
London buildings vary enormously. We regularly come across older terraces with ageing slate roofs, converted properties with awkward access, modern extensions with flat roofs and homes where previous repairs haven’t solved the underlying issue. That local experience helps us assess the work properly and recommend a practical way forward.

We believe customers should understand what work is being recommended and why. That means explaining the condition of the roof or structure in plain English, setting out the likely options and avoiding unnecessary work.
Before starting, we’ll assess the property, discuss the scope and provide a clear quotation. Once the project is underway, we keep communication open so you know how the work is progressing.
Good workmanship is important, but so is the way the job is managed. We aim to arrive when agreed, protect the surrounding areas, keep the site organised and leave the property tidy when the work is finished.
Why Us
We take pride in completing roofing and building work to a high standard. The parts that aren’t immediately visible matter just as much as the final appearance, so we pay attention to preparation, materials and correct installation.
Inviting builders or roofers onto your property requires trust. We treat every home and workplace with respect, communicate clearly and carry out the work in a professional manner from the first visit to completion.
Not every problem requires a complete replacement. Where a repair is suitable, we’ll say so. Where more substantial work is needed, we’ll explain the reasons clearly and help you understand the available options.
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’ll begin by talking through the issue or project, including any concerns you’ve noticed and the result you’d like to achieve.
We inspect the property, assess access and look closely at the areas involved. This allows us to understand the condition of the roof or building before making recommendations.
You’ll receive a quotation based on the work discussed. We aim to make the scope clear so you know what is included.
The project is completed carefully using suitable materials and proven methods. We’ll keep you informed, particularly if anything unexpected becomes visible once the work begins.
Before leaving, we check the completed work and clear the working area. We want customers to feel confident in both the finish and the way the project has been handled.
