There’s nothing like the sinking feeling of spotting a damp patch on the ceiling. Or hearing the telltale drip in the attic during a rainy London night.
A leaking roof isn't just annoying – it’s a sign that something’s gone wrong up top. But the big question is: do you need a straightforward repair, or is this the start of a bigger (and pricier) problem?
Let’s take a look at how roof leaks work, when to act, and how to know if you’re in for a quick fix or a full roof replacement.
First Off – Where’s the Leak Actually Coming From?
One of the most frustrating parts about roof leaks? The source isn’t always where the water shows up.
Water can travel along rafters, down under tiles, and drip down somewhere completely unexpected. That’s why leak detection isn’t guesswork—it’s an investigation. At Roof Local, we look for the actual entry point, not just the symptom.
Common culprits include:
Cracked or missing tiles
Damaged flashing around chimneys or skylights
Blocked or overflowing gutters
Valley joints where two slopes meet
Underlayment failure beneath the tiles
Quick Checklist: Signs You’ve Got a Roof Leak
Even before water starts dripping inside, you might notice:
Damp patches on ceilings or upper walls
Peeling paint or bubbling plaster
Mould or mildew smell in loft spaces
Increased heating bills (yes, really—leaks can impact insulation)
Watermarks around chimneys or light fittings
If you spot any of these, don’t wait it out. Roof problems rarely fix themselves.
Repair or Replace? The Questions to Ask
1. How old is the roof? If it’s under 20 years old and generally in good nick, chances are you’ll get away with a repair.
2. Is the leak isolated? A leak in one corner is probably a result of a slipped tile or dodgy flashing. If you’ve got multiple leaks across the roof, that’s a red flag.
3. Has this happened before? Recurring leaks in the same spot may suggest deeper issues, like underlayment failure or poor workmanship.
4. What’s the roof made of? Slate and clay tile roofs are often easier to patch than ageing felt roofs or interlocking systems that rely on precise positioning.
5. Any structural damage? If water’s made its way to your joists or insulation, it could be time to think bigger.
What’s Involved in a Leak Repair?
Every roof is different, but here’s how we usually handle it at Roof Local:
We inspect the loft space and roof exterior
Trace water trails back to the entry point
Remove affected tiles or slates
Replace damaged underlay or flashing
Refit tiles and reseal the area
We always use materials that match or blend with the existing roof, so your repair doesn’t stand out like a sore thumb.
When Replacement Makes More Sense
There are times when constantly patching leaks becomes a false economy. If your roof is 30+ years old, or you’re experiencing multiple points of failure, replacing it might be the most cost-effective option.
Signs it’s time to consider a replacement:
Widespread tile or slate deterioration
Rotten or sagging roof timbers
Leaks in more than one area
Previous patch jobs that didn’t hold
We’ll always give you the facts, not a sales pitch. If a repair will do the job, we’ll say so.
The Emotional Toll of a Leaky Roof
Leaks are more than just a maintenance issue. They trigger stress, anxiety, and even a bit of embarrassment. Who wants to explain that stained ceiling to guests?
At Roof Local, we get that. We don’t just fix leaks—we restore your peace of mind.
Prevention is Cheaper Than Repair
The best way to deal with leaks? Stop them before they start. Regular roof inspections—especially before winter—can catch minor issues before they become disasters.
We offer drone surveys, visual checks, and detailed reports to give you a full picture of your roof’s condition.
Worried that damp patch means serious trouble? Let Roof Local take a look. We’ll track down the source, explain your options, and help you move forward confidently – whether it’s a simple fix or time for something more.
