A single slipped tile can let rain reach the roof structure long before you see water dripping through a ceiling. That is why knowing how to spot roof storm damage soon after high winds, heavy rain or hail can save you from a much larger repair bill. The safest approach is to inspect what you can see from ground level, look indoors for early warning signs, and arrange a professional assessment where anything appears damaged or uncertain.
Storm damage is not always dramatic. A roof may still look broadly intact from the driveway while cracked tiles, lifted flashings or a blocked gutter are allowing water into vulnerable areas. Acting promptly protects the roof covering, timbers, insulation and the rooms below.
Start safely after the storm
Do not climb onto the roof, use a ladder in wet or windy conditions, or try to refit loose tiles yourself. Storm-damaged roofs can be unstable, and a minor repair is never worth the risk of a fall. Instead, wait until conditions are calm, then walk around the property and inspect the roof from several angles using daylight and, if helpful, binoculars.
Keep clear of fallen cables, damaged trees and any loose materials at height. If part of the roof is visibly hanging, water is entering rapidly, or a ceiling is bulging under the weight of water, treat it as urgent. Move valuables away from the affected area, contain drips where it is safe to do so, and call a trusted roofing contractor.
Taking clear photographs from the ground can also be useful. They provide a record of the condition immediately after the storm and help a roofer identify likely problem areas before attending.
How to spot roof storm damage from outside
The most obvious signs are usually missing, broken or displaced roof tiles and slates. Look for uneven lines in the roof covering, bare patches, fresh fragments on the ground, or tiles that appear raised compared with those around them. Wind can loosen fixings without removing a tile completely, so an area that looks slightly lifted deserves attention.
Roof valleys need particular care. These channels carry rainwater down the roof, and even a small obstruction or dislodged tile can force water underneath the covering. Check for leaves, branches and debris gathered in valleys or around chimney bases. Do not attempt to clear difficult-to-reach areas yourself.
Damaged ridge tiles and mortar
Ridge tiles run along the top of a pitched roof and are exposed to the full force of wind. Cracked mortar, gaps beneath the ridge, leaning tiles or pieces of mortar on the ground can all indicate movement. Older roofs may have traditional mortar bedding that has weakened gradually, then failed during a storm.
A loose ridge tile can become a falling hazard as well as a route for water ingress. It should be checked and secured quickly by an experienced roofer.
Flashing problems around chimneys and roof joints
Flashing is the material fitted around chimneys, dormers, skylights, vents and wall junctions to keep water out. Strong winds can lift lead flashing, split sealant, or loosen the mortar around chimney flashings. From ground level, you may notice a flashing edge that is curling up, a visible gap, or staining on the brickwork below.
These areas are common sources of leaks because water naturally collects and changes direction around them. A repair may be relatively straightforward when found early, but delayed action can allow damp to spread into roof timbers and internal finishes.
Guttering, fascias and soffits
Storm damage is not limited to tiles. Gutters can sag, separate at joints, overflow or pull away from the fascia board under the weight of rainwater and debris. Downpipes may become blocked or disconnected, leaving water to run down external walls rather than safely into drainage.
Look for water marks on brickwork, overflowing gutters during the next rainfall, loose brackets, cracked joints and sections that are visibly out of line. Check fascias and soffits for gaps, peeling paint, damp staining or bird entry points. These components help protect the roof edge and support effective drainage, so neglecting them can lead to avoidable damage.
Check indoors for early signs of a leak
A roof can leak for days or weeks before the problem becomes obvious. After a storm, inspect the loft first if it is safe and accessible. Take a torch and look for damp insulation, wet timbers, water trails, dark staining and droplets on roofing felt or membranes. A musty smell can also point to trapped moisture.
Do not mistake every mark for a new leak. Some older properties have historic stains from repairs completed years ago. The key question is whether the area feels damp, looks fresh, or has changed since your last inspection. Photograph anything suspicious so you can monitor it or show it to your roofer.
Inside living spaces, look closely at ceilings near chimneys, exterior walls, skylights and the upper corners of rooms. Brown or yellow marks, peeling paint, bubbling plaster and unexplained mould are all possible signs of water ingress. If a ceiling is bowed, soft to touch or actively dripping, keep people clear of the area and seek urgent help.
Different roofs show damage in different ways
Pitched roofs commonly suffer from cracked, slipped or missing tiles, damaged ridges and failed flashing. The type of tile matters: concrete tiles may crack under impact, while slate can split or lose its fixing. A professional inspection is the best way to establish whether isolated tiles can be repaired or whether wider deterioration is affecting the roof covering.
Flat roofs require a different check. Heavy rain can reveal ponding water that remains for more than 48 hours after dry weather returns. Look from a safe viewpoint for standing water, split seams, blisters, tears, lifting edges and damaged roof outlets. Water pooling does not automatically mean a roof has failed, but persistent ponding adds stress to the surface and may indicate poor drainage or a sagging deck.
If your property has a garage, extension or porch with a flat roof, do not overlook it simply because it is smaller. These roofs often sit beneath trees or beside taller roofs, making them more exposed to debris and concentrated runoff.
Know when damage needs prompt professional repair
Some issues should not wait for a convenient time. Arrange a prompt roofing inspection if you find missing tiles, damaged flashing, loose ridge tiles, a leaking ceiling, overflowing gutters, exposed felt, or debris that may have punctured a flat roof. The same applies if a tree branch has struck the property, even where the impact mark seems minor.
It depends on the extent of the damage whether you need a small repair, renewed flashing, gutter work or more substantial roof restoration. A reputable contractor should explain what has failed, show you the affected area where possible, and provide a clear quotation before work begins. Be cautious of anyone who calls uninvited after a storm, demands immediate cash payment, or insists a complete new roof is needed without a proper inspection.
Temporary weatherproofing can be valuable when rain is expected, but it is not a long-term solution. A correctly completed repair should restore the roof’s watertight protection and address the underlying cause, whether that is broken tiles, failing fixings, poor drainage or ageing materials.
Prevent the next storm from causing the same problem
Regular maintenance gives your roof a better chance of coping with British weather. Keep gutters and downpipes clear, particularly in autumn and after nearby trees shed branches. Have loose mortar, cracked tiles and worn sealants repaired before winter storms put them under greater pressure.
A visual check twice a year is sensible for most homes, with an extra inspection following severe weather. Properties with mature trees, older roof coverings, flat roofs or exposed locations may benefit from more frequent professional checks. Good maintenance is usually far more cost-effective than waiting for a leak to damage insulation, plasterwork and possessions.
