Roofing Services in London

Trusted roofing specialists based in Mayfair, covering all of Central London

A solid roof is the one part of your home you don't think about — until it fails. At OneSpace Roofing, we've spent years keeping London roofs watertight, warm and wind-proof. From Victorian terraces in Marylebone to the period properties lining Sackville Street itself, we understand the quirks of Central London roofing: listed-building restrictions, party-wall parapets, mansard slopes, hidden valleys, and the endless parade of seagulls and chimney stacks. This page walks you through every service we offer, so you can figure out what your roof actually needs — and what it'll take to put it right.

What we do

Our work falls into five core areas, and every job we take on is handled by our own roofers — never subbed out to a pop-up crew. Below is a quick overview of each service. Click through to any page to see pricing ranges, timelines, and the signs that tell you it's time to call us.

Flat roof repair and replacement

Flat roofs are everywhere in Central London — extensions, dormers, garage roofs, rear additions — and they fail more often than pitched roofs simply because water has nowhere to go. We repair, patch and fully replace flat roofs using EPDM rubber, GRP fibreglass, and high-performance felt systems. If you've got ponding, bubbling, splits or interior staining below a flat section, this is the page for you. See our flat roof repair service →

Roof leak repair

Leaks rarely come from where the stain appears. Water tracks along rafters, timbers and battens before dripping through, which is why DIY patches almost never solve the real problem. We diagnose the source — slipped slates, failed lead flashing, cracked mortar, blocked valleys, failed felt — and fix it properly the first time. More on leak repairs →

Full roof replacement

When a roof is past saving — widespread slate failure, rotten battens, sagging timbers, or a complete loss of thermal performance — replacement is the honest answer. We handle tear-offs and new builds on pitched and flat roofs, with insulation upgrades to current UK building regs. Roof replacement details →

Chimney repairs and repointing

London's period chimneys take a beating from acid rain, frost and wood-burner heat cycles. Loose pots, cracked flaunching, spalled bricks and failed lead aprons are the classics. We repoint, re-cap, re-flash and rebuild chimneys without disturbing the rest of the roof. Chimney work →

Gutter cleaning, repair and installation

Blocked gutters cause more internal damage in Central London than almost any other roof issue. Plane-tree leaves, pigeon debris, moss from neighbouring properties — it all pools into one overflow event. We clean, realign, repair and replace guttering in cast iron, aluminium and uPVC.

How we work

We keep the process deliberately simple, because roofing is stressful enough without surprise invoices and vanishing tradesmen.

1. Free callout and roof survey. You describe the issue over the phone; we book a visit, usually within 48 hours. For emergencies, same-day where possible.

2. Written quote, no pressure. Valid for 30 days.

 

3. Scheduled work. We show up when we say we will. One crew, one job, from start to finish.

 

3. Post-job walkaround. We show you what we did, hand over any leftover materials worth keeping, and explain the warranty (10 years on most major works).
