Know What You Are Looking At

Most roof problems give you advance warning before water actually reaches the ceiling. The difficulty is knowing which signs are urgent and which can wait a few weeks. Getting that wrong in either direction costs money - ignore a warning and a small repair becomes a large one; panic at something cosmetic and you pay for work you did not need.

This page is about the warning signs themselves: what they look like, what causes them, and what a roofer should do when they find them.

Warning Signs You Can See from the Ground

You do not need to go up a ladder to spot most early indicators. A walk around the outside of the house, with a careful look upward, will often show you enough.

• Slipped or missing tiles. A tile that has dropped to one side or slid down the pitch is usually a sign that the nibs (the small hooks that hold the tile to the batten) have broken, or that the batten itself has rotted. One slipped tile is a repair; a cluster of them suggests the batten run needs replacing in that area.
• Cracked or broken tiles. Concrete interlocking tiles crack more easily than clay plain tiles after a hard frost, because they absorb more water before it freezes. A single crack will let water in during heavy rain, but you may not notice until the timber below is already wet.
• Moss and algae coverage. Moss holds moisture against the tile surface and accelerates frost damage. It also grows between tiles and can lift them slightly. Treating moss and keeping gutters clear is genuinely preventative maintenance, not just cosmetic.
• Sagging or uneven roof lines. A roof that looks wavy along the ridge or between rafters is a structural warning. It can mean rotten or undersized rafters, a failed purlin, or long-term damp that has weakened the timber frame. This needs a roofer's eye at close range before you can assess the scope of work.
• Flashings pulling away from a chimney or wall. Lead or aluminium flashing seals the joint between the roof covering and vertical surfaces. When it lifts, opens at a step joint, or loses its mortar pointing, water tracks straight down the inside of the wall. This is one of the most common entry points for persistent leaks.
• Damaged or blocked gutters. Gutters that overflow soak the fascia board, soffit and the timber behind them. Rot in the fascia can spread to the rafter feet, which are structurally important. Gutters are not roofing, but blocked gutters cause roofing damage.

Warning Signs Inside the Property

By the time you see a stain on a bedroom ceiling, water has usually been sitting in the roof space or soaking into insulation for some time. The stain is rarely directly below the entry point - water follows rafters, runs along battens, and can travel a metre or more before dripping.

• Yellow or brown ceiling stains. Fresh stains feel damp to the touch. Old stains that are dry may mean a problem that comes and goes with wind-driven rain rather than steady downpours.
• Damp patches on a top-floor wall, particularly near a chimney breast. Often caused by failed flashing or cracked haunching (the mortar cap on a chimney stack).
• Mould on the underside of the roof deck or on rafters. If you can safely access your loft space, look for black or dark green mould on the timber. It is a sign of ongoing moisture, whether from a leak above or from condensation. A roofer can usually tell which from the pattern.
• A cold or damp smell in a top-floor room. Not conclusive on its own, but worth noting alongside any of the above.

What Actually Causes Roof Problems

Understanding the cause is what separates a lasting repair from one that fails again within a year. The three most common underlying causes are age and weathering, physical damage, and failed workmanship on a previous repair.

Age and Weathering

Roof tiles and slates do not last forever, though they last a long time when the original installation was sound. Clay plain tiles can perform well for well over a century; concrete interlocking tiles typically last 40-60 years before they become porous and start to degrade. When a tile reaches the end of its life, it absorbs water rather than shedding it, and frost breaks it apart from the inside out.

The bedding mortar used under ridge tiles and at verges also deteriorates. Lime mortar from older properties can crumble away over decades; sand-and-cement pointing cracks as the structure moves with temperature changes. Repointing ridge tiles is a straightforward repair, but it needs to be done properly - dry-fix ridge systems using mechanical fixings rather than mortar are now more durable and are worth considering on a full re-ridge job.

Physical Damage

Wind lifts tiles, particularly at verges and ridges where they get less support. A gale does not have to be extreme to shift a tile that was already slightly loose. Falling branches and aerial fixings work loose in wind and slide down the pitch. Any penetration of the tile covering, however small, is a potential leak in the next downpour.

Frost is the other major physical cause. Water gets into a hairline crack in a tile, freezes overnight, expands, and makes the crack larger. After a few cycles the tile splits. This is particularly noticeable on north-facing pitches that do not get enough sun to thaw quickly.

Failed Previous Repairs

A common cause of ongoing leaks is a previous repair that treated the symptom rather than the source. Applying roofing sealant over a cracked tile, for example, may hold for one winter but will not stop water getting under the tile at its edges. Mortar haunching applied over old mortar that has not been fully raked out fails faster than a fresh application on clean masonry.

When a repair keeps failing in the same place, it is nearly always because the actual cause has not been found. A thorough inspection looks at the whole area around the failure, not just the most obvious point.

What a Proper Inspection Involves

A roofer inspecting a repair job should get physically onto or close to the roof - binoculars from the ground are not enough when you need to check mortar condition, flashing laps and tile nail fixings. They should look at the area of reported damage and the area around it, check the loft space if accessible, and explain what they have found and why before starting work.

If there is structural timber damage or extensive tile degradation, the roofer should set out clearly what needs doing and why, so you can make an informed decision.
