Expert Roofers London

My name's John Quilligan. Roofing's been in my family three generations, and today I lead a team of uniformed, fully insured roofers working across London — with South London, South West London, and Surrey as where we focus most of our work. Every job gets my personal attention — I'm the one who quotes it, and I'm the one who stands behind the work once it's finished — but you're getting a proper team on your roof, not one man on a ladder hoping the weather holds.

Our vans are out on the road every day, our roofers work in matching hi-vis, and safety comes first on every single job — proper scaffolding and access where it's needed, not corners cut to save an hour. When you ring, you're talking to a family business three generations deep, with the trained team and the kit to actually back that up.

When something's wrong with your roof, the last thing you need is someone who quotes off a photo, sends a different face out each time, or "fixes" the same leak three times running. We work the opposite way: I inspect it properly myself — often with a drone if the cause isn't obvious from the ground — tell you exactly what's wrong and what it costs, and my team carries it out to the same standard every time.

No hidden extras. No callback in six weeks for the same leak. Every new roof comes with a 25-year guarantee, and every repair is backed for up to 10 years — in writing, not just a promise on the phone.

Choosing a roofer is a matter of trust. Here's what we bring to every job:

Three Generations of Experience on London Roofs

We've worked on every type of roof you'll find across London and Surrey — Victorian slate terraces in Tooting and Balham, 1930s semis in Sutton and Epsom, mansard conversions in Kingston, and flat roof extensions from Wimbledon to Surbiton. Local housing stock this varied punishes roofers who treat every job the same way. We don't.

We Find the Cause, Not Just the Symptom

A patch job that fails in three months costs you more than getting it right the first time. We inspect thoroughly — often with a drone survey where the cause isn't obvious from the ground — identify the root of the problem, and carry out repairs built to last, not to buy you a few dry weeks before it rains again.

Honest Pricing, No Pressure

You get a clear, written quote before any work begins. What we quote is what you pay — no add-ons, no "while we're up there" surprises at the end. If a repair will genuinely do the job, we'll tell you that instead of pushing a replacement you don't need.

Clean, Tidy Workmanship

We protect your property during every job — garden, driveway, and access paths — and leave the site clean when we're done. All waste is removed and your home is left in the same condition we found it, or better.

Written Workmanship Guarantee

Every new roof we install is backed by a 25-year guarantee. Every repair is covered for up to 10 years, depending on the work carried out. If something isn't right within that guarantee period, we come back and put it right — no arguments, no small print designed to get us out of it.

A roof problem rarely announces itself at a convenient time. Whether it's a leak appearing after a night of heavy rain, slates blown off in a storm, or a flat roof extension that's finally given up after one too many "patch-ups," you need a team that can respond quickly and fix it properly the first time.

We carry out repairs on every roof type found across our patch — slate, tile, flat, pitched, and everything in between. From leaking flashings and cracked ridge tiles to failed felt and blocked guttering backing up under the eaves, we've dealt with it.

What sets us apart is thoroughness. We don't just fix the obvious problem and leave — we check the surrounding area to make sure nothing else is about to fail behind it. A repair that's done properly lasts for years. That's the standard every job on our books gets held to.

How do I know if my roof needs professional attention? Common signs include water stains spreading across ceilings, missing or slipped tiles, moss build-up on a pitched roof, cracked flashing around chimneys or valleys, and roofing material found on the ground after a storm. If something doesn't look right, it's safer — and cheaper in the long run — to have it checked early rather than waiting to see if it gets worse.

Do you charge a call-out fee? No. If it turns out to be a five-minute fix, or your roof turns out to be fine, you're not charged for the visit.

How quickly can you get someone out? Same day, seven days a week, across South London, South West London, and Surrey — genuine emergencies get priority.

Do you use a drone for inspections? Yes. Where the cause of a leak isn't obvious from the ground, a drone survey often finds it in minutes without anyone climbing a ladder first — and gives you photo evidence of exactly what we found.

Are you insured and accredited? Yes — insured through Simply Business, and members of TrustATrader and CORC. Every member of our team is trained, uniformed, and covered under our insurance — not subcontracted out.

Do you offer a guarantee on repairs? Yes. Every new roof we install carries a 25-year guarantee. Every repair is covered for up to 10 years, depending on the work carried out — and it's given to you in writing, not just promised on the phone.

Do you cover North or East London? We're focused on South London, South West London, and Surrey — that's where our team and our knowledge of the local housing stock is strongest.

Between us, our team has worked on Victorian terraces in Tooting, 1930s semis in Sutton and Epsom, mansard conversions in Kingston, and flat roof extensions from Wimbledon to Surbiton. The problems aren't the same on all of them, and treating every roof the same way is how homeowners end up paying for the wrong fix.

Narrow valley gutters on period terraces trap water long before a tile ever fails — one job our team handled recently looked like months of unexplained damp until a drone survey found the real cause in minutes, nowhere near the tiles everyone assumed were the problem. 1930s tile nibs go brittle with age and let go in the first proper gale of the season — we see a run of these every winter, without fail.

Felt roofs from the 60s and 70s have usually been "patched" once already and are due a proper replacement, not a fourth Band-Aid that won't hold past the next wet spell. And London clay moves more than most homeowners realise — it's why chimneys crack and lean here years before anyone thinks to check the roof for it.

Knowing which of these is actually happening on your roof — rather than guessing — is the difference between a £200 repair and an unnecessary £8,000 replacement, or the other way round.
