Complete Roofing Solutions for Every Property
A roof is the single most important element of your home’s structure. When it’s time for a full replacement or a new installation, you need a team that understands both the technical demands and the character of your property — especially across North London’s mix of Victorian terraces, Edwardian villas, and modern extensions.
MJM Roofing delivers complete new roofs and re-roofing projects from start to finish. We handle everything — from the initial survey and scaffolding through to stripping the old covering, inspecting and repairing timbers, installing modern breathable membranes, and laying your chosen material with precision.
We work with natural slate, clay tiles, concrete tiles, and all modern flat roofing systems. Every project is completed to current Building Regulations, including Part L insulation upgrades where required, ensuring your new roof is energy-efficient, weatherproof, and built to last.

The Right Roof for Your Property
We work with every major roofing material, helping you choose the best option for your property’s style, location, and budget.
Natural Slate
The premium choice for London period properties. Welsh and Spanish slate offers unmatched longevity — often lasting 100 years or more — with a timeless appearance that enhances any home.
Clay Tiles
Beautiful hand-made and machine-made clay tiles in a wide range of colours and profiles. Excellent durability with a 60–80 year lifespan, perfect for both traditional and contemporary properties.
Concrete Tiles
A cost-effective and hard-wearing option available in profiles that replicate slate or traditional tile. A strong choice for properties where budget is a key consideration without compromising performance.
GRP Fibreglass
The modern standard for flat roofs. A seamless, fully bonded system that’s completely watertight with a life expectancy of 30+ years. Ideal for extensions, dormers, and garage roofs.
EPDM Rubber
A single-piece rubber membrane that delivers excellent weather resistance for flat roofs. Quick to install with minimal joints, reducing the risk of future leaks. Guaranteed up to 20 years.
Dry Ridge & Hip Systems
Modern mechanical fixings that replace traditional sand-and-cement mortar on ridges and hips. Maintenance-free, storm-proof, and compliant with current regulations. A smart upgrade for any re-roof.
How We Deliver Your New Roof
A clear, structured approach from first contact to final sign-off — so you know exactly what to expect at every stage.
Survey & Consultation
We inspect your existing roof, discuss material options, and assess whether any structural work is needed. You’ll receive a fully itemised quote with no hidden costs.
Preparation
Scaffolding is erected and your property is fully protected. We strip the existing covering and inspect the timber structure, making any repairs before the new materials go on.
Installation
New breathable membrane, insulation, battens, and your chosen covering are installed to manufacturer specifications and Building Regulations. Lead flashings, ridges and valleys are dressed by hand.
Completion & Guarantee
We carry out a final quality inspection, complete a thorough clean-up, and hand over your written guarantee. Scaffolding is dismantled and everything is left immaculate.
