Most roof problems do not announce themselves with an obvious hole or a sudden waterfall through the ceiling. They start quietly - a tile shifts a few millimetres, a lead flashing pulls away from the pointing, or moss builds up against a ridge tile and traps moisture against the mortar. By the time a water stain appears on your bedroom ceiling, the damage is often weeks or months old.
Catching the signs early keeps repair costs low. Ignoring them means a job that might have cost a few hundred pounds can turn into a full section re-lay or, in the worst cases, structural work to damaged rafters. This page walks through what to look for, what causes it, and when to call a roofer.
You do not need to climb onto the roof to spot most early warning signs. A pair of binoculars and a slow walk around the outside of the property will usually tell you a great deal. Look for:
Inside the property, damp patches on ceilings or walls near the eaves, a musty smell in the loft, or felt that has rotted away are all signs that water is getting in. Dark staining on rafters or insulation shows the problem has been active for some time.
Understanding what causes damage helps you know which repairs actually need doing and which fixes will hold. Roof failures rarely come from a single dramatic event - they are almost always the result of gradual deterioration that accelerates when wind, rain or frost hits a weak point.
Ridge tiles are bedded in mortar and are the highest, most exposed part of the roof. The mortar mix used on older properties was often lime-based, which moves with the structure but eventually erodes. On more recent repairs, a hard cement mortar can crack as the roof deck flexes slightly in the wind, leaving the tile loose on top. A loose ridge tile is a common cause of sudden leaks because water can drive under it in heavy rain.
A proper repair means removing the affected tiles, cleaning off the old mortar, re-bedding with a suitable mortar mix, and re-pointing the joints. Some roofers now use a flexible dry-fix system for ridge tiles, which removes the reliance on mortar entirely and tends to hold up better over time.
Natural slate is durable but can be let down by the nails that hold it. Galvanised nails corrode over time - a problem sometimes called nail sickness - and when the nail fails the slate is held only by friction against its neighbours. One wind event is then enough to shift or drop it. Replacing individual slates is straightforward when there are matching slates to hand.
Cracked slates are more often the result of foot traffic - either a previous repair done without the right boards, or debris impact. A crack that runs through the fixing hole will eventually cause the lower half of the slate to drop, so a cracked slate should be replaced rather than left.
The junction between a vertical surface - a chimney stack, a dormer wall, a parapet - and a sloping roof is sealed with lead flashing. Lead is the material of choice because it is malleable and long-lasting, but it is not permanent. It can crack under thermal movement, pull away from the mortar joints it is tucked into (called chases), or lift if the pointing around it fails.
The flat or shallow-pitched roof section over a bay window is often sealed with torch-on felt or older bitumen felt, and the junction with the main wall is typically flashed with lead or, on older properties, with mortar fillet pointing. Both can fail without any obvious visible sign from the ground. If you have a persistent damp patch above a bay window, the flashing or felt membrane is the first place to check.
Moss itself does not damage tiles, but the way it retains moisture does. A thick moss covering keeps the tile surface wet for far longer after rain, and repeated wet-dry-freeze cycles accelerate the breakdown of the surface. On concrete tiles, this leads to surface delamination. On clay, it can cause spalling at the edges. Moss also works its way into tile joints and, when it dies back, leaves a debris plug that channels water sideways rather than down the slope.
Removing moss by high-pressure washing can dislodge tiles and drive water into the roof structure - it is generally not recommended. Biocide treatment that kills the moss and lets it dry out and blow away over a few months is safer for the roof covering. Any repairs to tiles underneath should be done after the moss has cleared, so the full extent of the damage is visible.
Felt flat roofs over extensions, garages and porches have a limited lifespan. Standard built-up felt typically lasts 10-15 years before the surface starts to crack and blister. Splits that appear in summer when the felt expands are often invisible in winter when it contracts, making them hard to spot until a dry spell ends. A good repair involves cutting back to sound material, drying the deck thoroughly, and applying a compatible patch or new layer - not simply brushing on roof paint, which is a temporary measure at best.
