A slipped tile after a windy night can look like a minor job from the driveway. But one gap in the wrong place can let rain reach the roof felt, battens and loft insulation long before a damp patch appears indoors. Knowing how to inspect roof tiles from ground level helps you spot problems early, without taking unnecessary risks.
For most homeowners, a regular visual check is enough. You are looking for changes, damage and signs that water is not being carried away properly – not trying to carry out a full roof survey yourself. If something looks wrong, a local roofer can inspect it safely at close range and advise whether it needs a small repair or more substantial work.
Start with safety, not the ladder
Roof work is not a DIY job for most people. Tiles can be slippery even when they look dry, ladders need secure footing, and older roofs may have fragile areas that are not obvious from below. Walking on tiled roofs can also crack sound tiles or dislodge those already weakened by age and weather.
Inspect from the ground where possible, using binoculars or your mobile phone camera zoom. Choose a dry, bright day with little or no wind. Stand well back from the property so you can see the full slope, then look along each row rather than staring at one spot. Changes in the roof line are often easier to see from across the road or from the bottom of the garden.
If you use a ladder to look at the eaves or guttering, do not climb onto the roof. The ladder should be on firm, level ground and properly secured. Where there is any doubt, especially around a chimney, steep roof or high gable, leave the close inspection to a professional.
How to inspect roof tiles from the ground
Start at the ridge – the line of tiles along the top of the roof – and work downwards. A sound tiled roof should look broadly even, with consistent lines and no obvious gaps. You are not expecting perfection on an older property, but you should be able to spot sudden changes.
Look first for tiles that have slipped down, lifted at one edge or disappeared completely. A slipped tile may sit lower than the row around it, while a lifted tile can cast a darker shadow beneath its bottom edge. Missing tiles are usually easier to notice after rain because the exposed underfelt may look darker than the surrounding roof.
Then check whether any tiles are cracked, chipped or broken. Small corner chips do not always mean water is getting in, particularly if the overlap is still covered by the tile above. A crack through the middle, a broken lower edge or a tile split around its fixing point is more concerning. Frost can worsen these defects over winter, and strong winds can lift a damaged tile completely.
Pay attention to the pattern, not just individual tiles. Several tiles sitting unevenly in the same area can point to a fixing issue, worn battens beneath, or movement in the roof covering. This is one reason a quick patch is not always the right answer. The visible tile may be the symptom rather than the whole problem.
Check the ridge and verge tiles
Ridge tiles are exposed to wind and weather from every direction. Look for gaps in the mortar, loose pieces of bedding, cracked ridge tiles or a ridge line that appears uneven. If you can see daylight under a ridge tile from the ground, or parts of the mortar have fallen onto the path below, arrange an inspection promptly.
At the edges of the roof, inspect the verge tiles. These run up the gable end and are more exposed in windy weather. Crumbling mortar, loose tiles or gaps at the edge can allow wind-driven rain underneath the roof covering. On some homes, dry verge systems replace mortar, so look instead for loose caps or sections that have moved out of line.
Look closely around chimneys and roof junctions
Tiles are only one part of keeping rain out. Leaks often begin where the roof meets a chimney, dormer, wall or valley. Check for damaged tiles nearby, but also look for loose flashing, missing mortar or staining below the chimney breast inside the loft.
Valleys are the channels where two roof slopes meet. Leaves, moss and debris can collect there and stop water flowing freely. From ground level, look for a dark build-up, plant growth or water marks on the tiles below. A blocked valley can force rain sideways beneath tiles, so it is worth dealing with before the next spell of heavy weather.
Check the guttering at the same time
A tile inspection is a good opportunity to look at the guttering, fascias and soffits. Water overflowing from gutters can soak the roof edge and make a problem appear to be a tile leak when the gutter is actually blocked, poorly aligned or damaged.
After rainfall, watch where the water goes. It should flow steadily towards the downpipe, not spill over the front or back of the gutter. Look for sagging sections, joints that drip, vegetation growing from the gutter and staining on the brickwork beneath. Also check for pieces of tile, mortar or granules on the ground. They can be useful clues that something higher up has deteriorated.
Moss on roof tiles is common in West Yorkshire, particularly on shaded slopes. A light covering is not automatically a roofing emergency. Heavy moss growth, however, holds moisture and can block gutters as it breaks away. Avoid pressure washing or scraping tiles from a ladder, as this can damage the surface and dislodge the roof covering. A roofer can advise whether cleaning is worthwhile and how to do it without causing further problems.
Use your loft to spot early warning signs
A roof can look fine from outside while allowing small amounts of water through. If it is safe to enter your loft, take a torch and inspect it during daylight. Do not stand on the insulation or ceiling plasterboard – use boarded areas only.
Look for damp staining on timbers, dark marks on the underfelt, wet insulation, mould, or a musty smell. Daylight visible through the roof is another clear sign that tiles, flashing or roof coverings need attention. Check around chimney stacks and along the eaves, as these are common places for water to show first.
Condensation can sometimes be mistaken for a leak. If the dampness is widespread rather than concentrated in one area, poor loft ventilation may be involved. A roofer can help identify the cause, but it may also be necessary to assess ventilation and insulation rather than simply replacing tiles.
When should roof tiles be inspected?
A visual check twice a year is sensible – usually in spring and autumn. Spring checks can reveal damage caused by winter frost and storms, while autumn is a good time to clear gutters and prepare for heavier rain and falling leaves.
You should also inspect the roof after high winds, exceptionally heavy rain, hail or a fallen branch. Do not wait for a ceiling stain if you notice a tile on the ground or hear something moving in the wind. Fast attention can often keep a straightforward tile repair from becoming damaged battens, wet insulation or internal decorating work.
Older roofs may need more regular professional checks. The right interval depends on the tile type, the age of the roof, the amount of tree cover and whether previous repairs have been carried out. A roof that has performed well for decades can still develop isolated faults around ridges, valleys, chimneys and roof edges.
Signs it is time to call a roofer
Call for professional advice if tiles are missing, loose or broken, if mortar is falling from the ridge or verge, or if you see water entering the loft. A roofer should also inspect recurring gutter overflows, a sagging roof line, visible gaps around flashing, and any leak that appears during wind-driven rain.
It is tempting to wait until several repairs can be done at once. That can make sense for cosmetic issues, but not for faults that expose the roof beneath. Water damage rarely stays in the same small area, and timber repairs cost more than replacing one or two tiles while the rest of the roof is dry.
A clear inspection and an honest explanation matter. The best course may be a simple replacement tile, repointing to the ridge, repair to flashing, gutter clearance, or a wider repair where the underlying structure has been affected. It depends on what is found, not on selling work that is not needed.
If something does not look right, take a few clear photos from the ground and get it checked before the weather tests it again. For homeowners in Castleford and the surrounding area, 5 Towns Roofing can assess the condition of a tiled roof and explain the practical options without the guesswork.
