Roof repair in Sussex: my honest, no‑nonsense guide

When customers ask me about roof repair, they're usually already worried: there's a stain on the ceiling, a bit of damp in the bedroom, or a tile on the driveway after a windy night in Brighton or Worthing.

In my 18 years on the roof, I've noticed one thing again and again: small roofing problems turn into big, expensive ones when they're ignored. This page is where I walk you through how I look at roof repairs, how I decide what actually needs doing, and how I keep costs under control for you.

First things first: is it really a roof emergency?

I always split problems into two types in my head:

  • Emergency issues – water coming in right now, ceiling sagging, electrics at risk, or active dripping during rain.
  • Non‑urgent issues – stains that have been there a while, loose tiles spotted from the ground, or old flat roofs starting to crack but not yet leaking indoors.

If you've got water actively coming in, my honest advice is: treat it as urgent. Even a small leak can ruin plasterboard, flooring, kitchen units, or electrics surprisingly quickly.

If you're in Brighton, Hove or nearby and water is getting in right now, you can use my priority roof leak repair booking to get straight into my schedule for emergency attendance.

How I actually diagnose a roof problem

A lot of people are scared of calling a roofer because they're worried they'll be told they need a whole new roof when they only need a small repair. If you ask me, I'll tell you straight: you don't replace a roof that can be sensibly repaired.

Here's how I approach every repair job, step by step:

1. Start inside the house

  • I look at stains on ceilings and walls – shape, size, and direction tell me a lot.
  • I check in the loft if possible – wet timbers, mould, daylight through the roof, damp insulation.
  • I look for repeated repairs or bodged fixes from years past.

2. Look at the outside from the ground

  • Missing or slipped tiles or slates.
  • Damaged or sagging gutters overflowing onto brickwork.
  • Cracked or poorly fitted lead flashing around chimneys and walls.
  • Flat roof surfaces that look blistered, crazed, or ponding water.

3. Get safely up to roof level

Once I'm up there, I can usually pinpoint the problem quickly:

  • On pitched roofs: broken tiles, rotten battens, failing felt, lifted ridge tiles, or cracked mortar.
  • On flat roofs: splits at upstands, failed joints, poor detailing around pipes and skylights, or older felt that's simply at the end of its life.
  • On leadwork: slipped or cracked flashings, missing cover flashings, or cement where lead should have been used.

Only once I've gone through this process do I decide whether you need a targeted repair or if it's throwing good money after bad and you'd be better off planning a proper replacement.

Targeted repair vs full replacement: how I decide

Here is my honest advice on how I make that call on site:

When a local repair makes sense

  • The rest of the roof covering is in decent condition for its age.
  • The leak is clearly coming from one small area – a few broken tiles, a cracked flashing, a single bad joint on a flat roof.
  • There is no widespread rot in the timbers, and the underlay/membrane isn't crumbling everywhere.
  • You just need to get another few years out of the roof before a planned extension or bigger renovation.

When I tell people a replacement is more honest

  • The covering is simply worn out – brittle, crumbling felt; tiles that flake in your hand; or decades‑old patch repairs everywhere.
  • Leaks are coming from multiple areas, not just one obvious fault.
  • The batten and felt under a tiled roof are failing across large sections.
  • You've already paid for several repairs in recent years and it's still letting water in.

I know a full replacement sounds scary, but sometimes constant repairs cost more in the long run. When that's the case, I'll explain it clearly, price it properly, and let you decide in your own time.

Common types of roof repairs I carry out locally

Here's how I usually tackle different parts of a typical Sussex roof.

Pitched roof repairs (tiles and slates)

On a pitched roof, a lot of leaks come from fairly predictable spots:

  • Broken, cracked or slipped tiles.
  • Loose ridge tiles along the top.
  • Valleys where two roof slopes meet.
  • Chimney areas and side abutments with poor flashing.

Depending on what I find, a repair might involve:

  • Carefully lifting and replacing a run of damaged tiles or slates.
  • Resetting or rebedding ridge tiles, sometimes with a modern dry ridge system.
  • Repairing valleys – either relining them or replacing damaged tiles around them.
  • Renewing the lead flashing and pointing around a chimney.

If your leak is more about the underneath – rotten battens or torn felt – it may need a section stripped back and rebuilt. When that's the case, I'll usually reference the sort of work I explain on my roof batten and felt replacement service page so you have a clear idea what's involved.

Flat roof repairs

Most flat roof problems I see are on older felt roofs that are:

  • Cracked where the roof meets a wall or upstand.
  • Blistered or crazed from years of sun and weather.
  • Pooling water in the middle because the fall was never set correctly.

For flat roofs, a repair might be:

  • Stripping back and refelting just the failed area with compatible materials.
  • Reforming upstands, corners and details properly.
  • Adding a new cap sheet to give a tired but basically sound roof a few more years.

But I won't pretend: if the whole surface is shot, the right answer is usually a new system rather than patching every winter. If you're trying to work out whether repair or replacement is better for your flat roof, I go into more detail on my flat roof repair and replacement service page.

Lead flashing repairs

Lead is one of those parts of the roof that often gets overlooked, but it's critical around:

  • Chimneys.
  • Where a roof meets a wall.
  • Bay windows, dormers and parapet walls.

Common issues include:

  • Cement mortar alone used instead of proper lead work.
  • Short lengths of lead that split with movement.
  • Flashings that have pulled out of the brickwork joint.

A proper lead repair usually means renewing the flashing correctly rather than just smearing more mastic on it. If you want to understand how I approach this in more depth, have a look at my page on professional lead flashing repair and installation.

Gutters, fascias and soffits

Not every "roof leak" actually comes from the roof covering. Very often I'm called out for a leak and discover:

  • Gutters overflowing directly into the brickwork.
  • Downpipes blocked or not connected properly.
  • Old fascia boards rotten so the gutter fixings are pulling out.

A simple gutter repair or replacement can sometimes solve what looks like a much bigger problem. If I suspect that, I'll show you exactly what's happening and talk through options like the work I describe on my guttering and downpipe installation service.

What I look at before I quote for any repair

When I come out to see you, I'm not just looking at the leak itself. I'm thinking about:

  • Access and safety – Can I do it from ladders, or will it sensibly need scaffolding?
  • Future work you have planned – Are you planning a loft conversion or extension?
  • How long you want the repair to last – Are you selling soon, or is this your forever home?
  • Previous repairs – I can usually see what's already been tried and whether it actually helped.

I then use all of that to decide whether to suggest a quick, targeted fix, a more robust repair, or a complete roof replacement.

Costs: how I keep roof repair pricing clear and fair

The roofing trade has a bad reputation for vague pricing and nasty surprises. I run things differently:

  • Instant online estimates – For some types of work, you can get a realistic ballpark price on my website before you even speak to me.
  • Free on‑site inspection – If the estimate looks reasonable, I come out, inspect the roof properly, and confirm what's actually needed.
  • Fixed‑price quote – Once I've seen the job, I give you a written fixed price. No "it might be more on the day" games.

If you want me to take a look at your roof anywhere in Brighton, Hove, Worthing or nearby, you can use my free roof inspection booking page to pick a time that suits you.

What I actually do on site during a repair

When I turn up to repair your roof, here's what you can expect from me step by step:

  1. Walk‑through with you – I start by looking at the problem from inside the house, so we both agree on what we're trying to fix.
  2. Set up access and protection – Ladders, boards or scaffolding if needed, and dust sheets inside if I have to open anything up.
  3. Open up the problem area – Carefully remove tiles, felt, or sections of flat roof around the suspected leak.
  4. Check the timber underneath – If anything is rotten, I replace it properly rather than just covering it up.
  5. Install the repair – Tiles, felt, lead, or new flat roof sections fitted to the correct standards, not just "good enough for today".
  6. Test where possible – I always visually check and, when it's sensible, run water over the area to confirm it sheds correctly.
  7. Show you photos – Through my online client portal, you can see before, during and after photos of exactly what I've done.

Preventing future roof repairs: what you can do as a homeowner

A lot of expensive repairs I'm called to could have been avoided with a bit of simple maintenance. Here are the things I always recommend to my customers:

  • Keep gutters clear – Blocked gutters are one of the biggest causes of damp around roof edges.
  • Look up after storms – If you see a missing tile or something hanging loose, get it checked before the next spell of heavy rain.
  • Don't ignore small stains – A tea‑cup sized mark on a ceiling can mean a lot more going on above.
  • Check flat roofs every year or two – Especially garages and extensions that people forget about until water is pouring in.

If you have an older garage or extension and you're not sure whether it needs repair or replacement, it's worth getting a rough idea of costs ahead of time. You can use my garage flat roof cost calculator to see what a proper solution might look like budget‑wise.

How I keep you in the loop during any repair

A big part of why people are nervous about roofers is that work happens overhead where you can't see it. That's why I use a simple online client portal for every job:

  • Daily photo updates showing what I've done.
  • Clear schedule so you know what's happening and when.
  • All quotes, invoices and warranties stored in one place.

You shouldn't have to climb a ladder to know what's going on with your own roof. My job is to make the whole process as transparent and stress‑free as possible.

When you should definitely call me in

Here are the situations where, in my opinion, you shouldn't put it off:

  • You can see daylight through your loft where the roof covering should be.
  • You have water actively dripping indoors during rain.
  • A patch repair has already been tried and failed.
  • There is visible sagging in the roof line.
  • Mould is appearing on ceilings or high up on walls near the roof.

If you recognise any of these signs on your Sussex home, get in touch. I'll come out, give you a straight explanation of what's going on, walk you through the options, and give you a fixed price so you can decide what makes sense for you and your roof.
