A slipped tile can look like a small issue from the ground, yet one gap in the right place may allow wind-driven rain into the roof space. By the time a brown mark appears on an upstairs ceiling, water may already have affected battens, felt, insulation or timbers. Knowing how to inspect roof tiles gives homeowners a sensible way to spot warning signs early, without taking unnecessary risks.
The key word is safely. Most roof checks can and should be completed from ground level using a clear view of the roof, binoculars or a mobile phone camera with zoom. Walking on a pitched roof is not a DIY job. Tiles can crack underfoot, surfaces can be slippery even when they look dry, and a fall can have serious consequences.
Start with a safe ground-level roof check
Choose a dry, bright day with good visibility. Stand well back from the property and look at each slope of the roof from more than one angle. A pair of binoculars can help, but do not become so focused on one tile that you miss the overall shape and condition of the roof.
Start at the ridge, the highest line where the two roof slopes meet, then work your eye down towards the eaves. Tiles should sit in consistent, tidy rows. One tile that is visibly raised, shifted sideways or missing altogether deserves attention. On older roofs, slight variation can be normal, but obvious gaps and uneven lines are not something to ignore.
Do not lean a ladder against the guttering or climb onto the roof for a closer look. Guttering and roof edges are not designed to take that kind of load, and reaching a damaged tile can create further damage. If your inspection suggests a problem, a professional survey is the safer next step.
How to inspect roof tiles for common damage
A roof tile does not always need to be broken to cause trouble. Storms, frost, ageing fixings and repeated weather exposure can all affect how securely tiles sit and how well water is directed away from the roof.
Look for missing, slipped or cracked tiles
Missing tiles are usually the easiest defect to identify. You may see a patch of darker underfelt, timber battens or a clear interruption in the tile pattern. Even a single missing tile can expose the roof beneath to rain and wind, particularly on an exposed elevation.
Slipped tiles often sit lower than the surrounding row or appear out of line. This can happen when nails or clips fail, or when the underlying battens have deteriorated. A slipped tile may still seem to cover the roof, but the overlap that keeps water out may no longer be doing its job.
Cracks can be more difficult to see from below. Look for a tile that has a distinct line across it, a broken corner or an irregular edge. Concrete tiles can become more porous with age, while clay tiles can crack after frost or impact. It is not always possible to judge the full condition from ground level, which is why a close professional inspection can be worthwhile where there are several suspect tiles.
Check the ridge and edge tiles
Ridge tiles and hip tiles sit along the highest and angled edges of the roof. Because they are more exposed, they can work loose over time. Watch for gaps in the bedding, cracked mortar, displaced ridge pieces or sections that appear uneven.
Loose ridge tiles should be dealt with promptly. They are exposed to strong winds and, if they move further, can become a danger to people and property below. Modern dry-fix systems are often used on replacement roofs, but the right repair depends on the existing roof construction and overall condition.
Also inspect the verges, which are the tiled edges at either end of a roof slope. Crumbling mortar, loose tiles or visible gaps here can allow rain to track beneath the covering. Birds can also take advantage of openings around the edges, creating a problem in the roof space.
Pay attention to valleys, chimneys and roof windows
The areas where roof surfaces meet are often where leaks first develop. Valleys carry a high volume of rainwater, so leaves, moss and debris can quickly cause blockages. From the ground, look for vegetation build-up, tiles that seem out of place beside the valley, or staining below it.
Around chimneys, inspect the lead flashing and the surrounding tiles for obvious gaps, lifting or damaged mortar. A leak near a chimney is not automatically a tile problem. It may be caused by flashing, pointing or a fault higher up the roof. The same applies around roof windows, soil pipes and other penetrations. Finding the visible symptom is useful, but the cause needs to be correctly diagnosed before repairs are carried out.
Check from inside the loft as well
A dry-day check inside the loft can reveal issues that are not obvious from outside. Take a torch, step only on boarded areas, and avoid disturbing insulation or wiring. You are looking for signs of water getting past the roof covering, not trying to carry out a repair.
Dark staining on timber, damp insulation, mould, water marks and a musty smell can all point to moisture. Look particularly around chimneys, valleys and roof edges. If possible, inspect after heavy rain as well, but never enter a loft during a storm if conditions feel unsafe.
Bear in mind that condensation can sometimes be mistaken for a roof leak. Poor ventilation in the loft can create moisture on the underside of felt and timbers, especially in colder months. A roofer should assess the roof covering, while ventilation concerns may need to be considered alongside the condition of insulation and the roof space.
Do not mistake moss for the main problem
Moss is common on shaded or north-facing roof slopes across the Midlands. A light covering is not always an immediate concern, but heavy growth can hold moisture, block gutters and lift tile edges as it spreads. It can also hide cracked or damaged tiles from view.
Avoid aggressive pressure washing. This can crack tiles, strip protective surfaces from some concrete tiles and force water beneath the roof covering. Brushing or scraping from the roof is also risky without the right access equipment and experience. If moss is extensive, the roof should first be checked to make sure there are no underlying defects that need repair.
Know when a roof inspection needs a professional
A visual check is useful for routine home maintenance, especially after strong winds, heavy rain or prolonged frost. However, some signs call for a proper roofing inspection rather than watchful waiting. These include repeated leaks, several slipped tiles, loose ridge work, a sagging roof line, crumbling mortar, or daylight visible in the loft.
Age matters too. If the roof is approaching the later part of its expected life, isolated repairs may still be sensible, but the condition of the wider roof needs to be considered. Replacing one tile is very different from addressing worn felt, failing battens and widespread tile movement. A good roofer will explain whether a targeted repair, maintenance work or a larger reroofing project is the most practical option.
For homeowners in Nottingham and the surrounding Midlands, MTF Roofing Ltd can inspect tile roofs, identify the source of problems and provide clear advice on the work required. A proper survey should focus on the condition of the roof as a whole, not simply the first visible defect.
A simple inspection routine helps prevent larger repairs
Inspect your roof from the ground twice a year, ideally in spring and autumn, and again after severe weather. At the same time, look at gutters, downpipes, fascias and soffits. Overflowing gutters can send water onto brickwork and roof edges, while damaged roofline components can make an otherwise sound roof more vulnerable.
Take a few photographs from the same positions each time. This makes gradual movement, worsening moss growth or changes around the ridge easier to spot. There is no need to become an expert in roof construction. The aim is to notice changes early and arrange help before a minor defect turns into internal water damage.
A roof protects everything beneath it, so small warning signs are worth taking seriously. If something does not look right from the ground, leave the close inspection to a qualified, insured roofer and get the issue assessed before the next spell of bad weather.
