The clearest signs you need a roofer are damp patches on top-floor ceilings, slipped or missing tiles, displaced ridge tiles, and daylight visible through the roof from inside the loft. Active water ingress or fallen tiles need same-day attention. Most emergencies are the final stage of years of undetected deterioration.
Most roofing emergencies don't come from nowhere. The leak that appears after a winter storm usually has a backstory: a flashing that's been lifting for two years, tiles that were borderline last summer, ridge mortar that crumbled in the previous freeze. Catching the warning signs before a storm or a sustained cold snap turns them into an emergency saves money and prevents secondary damage to your interior.
None of these checks require getting on the roof. They require a pair of eyes, sometimes a torch, and 20 minutes.
Stand back from your property and look at the roofline. Tiles should lie uniformly in level courses. A tile that sits higher than its neighbours, has rotated out of alignment, or is visibly missing has either lost its nail fixing or been displaced by a previous storm. One slipped tile doesn't mean the roof needs replacing, but it does mean someone needs to get up and fix it — and check whether surrounding tiles are similarly unfixed.
On post-war estates across Ashford, Folkestone and Maidstone, slipping concrete tiles are typically the first visible sign of systemic nail sickness.
The ridge — the apex line of the roof — should be straight when viewed from the ground. A ridge line that dips, rises or has individual tiles sitting at different heights indicates either ridge tile mortar failure (the bedding that holds ridge tiles in place) or, in more serious cases, movement in the roof structure beneath. Ridge mortar failure is a maintenance repair. Structural movement is a different matter and needs prompt professional attention.
A damp or stained patch on a ceiling below the roof is the most obvious internal indicator of a roof problem — but the leak source is rarely directly above the stain. Water tracks along rafters, battens and sarking felt before it drips onto the ceiling. A stain above the bedroom window may be sourced from the flashing at the chimney on the other side of the roof. If you see damp patches, the first call is to a roofer, not a plasterer.
On a bright day, go into your loft space with the hatch closed (to eliminate light from below) and look at the underside of the roof. Any pinpoints or streaks of daylight indicate gaps in the tile covering or perforations in the underlay. Small amounts of daylight through old felt underlay are not necessarily urgent — old felt becomes translucent as it ages. But actual daylight through tile gaps indicates displaced tiles or missing mortar that needs attention.

Book Free InspectionWhen you clear your gutters — or when a gutter cleaning company does it for you — pay attention to what comes out. Granules of concrete or fragments of tile material in the gutters indicate surface erosion on concrete tiles. Small amounts are normal on ageing tiles. Heavy granule accumulation indicates accelerating surface degradation. This is not an immediate emergency but it tells you the tiles are in the late stages of their service life.
Moss on a roof surface is common in Kent, particularly on north-facing pitches and in areas with heavy tree cover such as Willesborough in Ashford or the Weald villages. Light moss coverage is largely cosmetic. Heavy, established moss is worth treating for two reasons: it retains moisture against the tile surface (accelerating any existing freeze-thaw damage), and it can work under tile edges and lift them slightly. Thick moss on flat roofing is more serious — it retains water and can penetrate surface defects.
A roof surface that sags between rafters, or a section of roof plane that has visibly dropped relative to the surrounding surface, indicates structural damage or rot in the underlying timber. This is not a cosmetic issue. Sagging roof decking is typically caused by prolonged water ingress that has rotted the boarding or purlins, by woodworm in the structural timbers, or — more rarely — by undersized original structure. Any visible sagging warrants prompt professional inspection.
This is the least obvious sign on this list but it's a real one. A roof that has perished underlay, missing tiles allowing direct air infiltration, or degraded insulation from prolonged moisture exposure loses heat significantly faster than an intact roof. If your heating bills have risen without obvious explanation and other causes (boiler efficiency, windows, doors) have been ruled out, a roof inspection is worth including in your diagnosis.
Ground-level visual inspection: once a year, ideally after the first autumn storms have passed. You're looking for the signs above. This takes 10 minutes and costs nothing.
Professional inspection: every 5–7 years for properties built before 1980, every 8–10 years for modern properties, and every 3–5 years for coastal properties in Folkestone, Hythe and the Kent coast where the salt air environment accelerates deterioration of all metal components.
After any significant storm: always worth a ground-level check the morning after, and a professional inspection if you see anything that concerns you.

Ashford's housing stock spans five decades of construction: Victorian and Edwardian terraces in Newtown and the older town streets, 1930s semis in Kennington and Willesborough, post-war and 1960s estates at Bockhanger, Stanhope and Park Farm, and more recent development across the southern suburbs.
Each era presents different characteristics. Victorian clay tile on period properties requires matching reclaimed material and lime mortar at any repointing work. 1960s concrete interlocking tile on the estates is now 50-65 years old with corroded nail fixings on most unmodified properties. Understanding which housing era a property belongs to is the starting point for any assessment.
These estates are Ashford's highest-volume source of roofing work. The 1960s-70s concrete interlocking tile stock is now 50-65 years old. Nail sickness is present on the majority of unmodified properties. If you live in one of these areas and have not had roofing work in the last 15 years, a free assessment is worthwhile.
The Victorian terraces in Ashford's Newtown area and the older streets around the town centre require period-appropriate specification: reclaimed or reproduction clay tile, lime mortar at chimney repointing, and conservation-aware approach to any work on visible elevations.

For re-roofing projects where deck condition is unknown before stripping, we include a clear provisional allowance for batten replacement rather than presenting you with a surprise on invoice.

Damp patches on top-floor ceilings, slipped or missing tiles, displaced ridge tiles, and daylight visible through the roof from the loft are the clearest signs.
Active water dripping through a ceiling, fallen tiles presenting a safety risk, or visible structural deformation need same-day or immediate attention.
Yes. A loft inspection on a bright day showing daylight, damp staining or perished underlay is the most useful self-check. Ground-level binocular inspection identifies ridge and tile issues.
Most emergencies are the final stage of years of undetected deterioration. Annual inspection and a survey every 5-10 years converts emergency costs into planned maintenance.
