It’s easy to leave a property viewing remembering the kitchen island and sunny bedrooms. Unless something looks obviously wrong, you barely give the roof a glance.
A dry ceiling on viewing day doesn’t reveal how the house handles heavy rain. Small defects can go unnoticed until a storm exposes them, leaving you with repairs you hadn’t budgeted for.
What you can spot from the ground
According to Connoisseur Roofs, a visual check of the roof can help buyers spot issues that warrant further investigation. Before heading inside, step back and look along the roof lines. Is there a noticeable dip, sag or uneven section? This warrants further investigation because it could point to a roofing or structural problem.
On tiled roofs, look for missing or cracked tiles, which can create openings for water. Visible rust or corrosion on metal roofs needs attention. Damaged fasteners and deteriorating seals are harder to see, but they’re worth having checked. Also look for sagging gutters and obvious debris that interfere with drainage.
These clues don’t mean the property is a poor buy, but they give you a reason to ask questions.
Look inside for clues
During the viewing, look up in every room, including cupboards and tucked-away corners. Water stains or mould suggest previous or ongoing water ingress.
A recently repaired ceiling is worth asking about too. Was the source of the damage fixed, or was the ceiling only patched and painted?
Damp can have several causes, so don’t assume every mark comes from the roof. Equally, don’t dismiss a stain because it feels dry, because some leaks only make an appearance when it rains.
The areas you can’t easily inspect
Some vulnerable areas are difficult to assess from the garden.
Ridge caps along the roof’s peak and hip sections can loosen as their bedding mortar deteriorates. Valleys, where roof slopes meet, carry concentrated rainwater and can develop problems through debris buildup or damage.
Flashing around chimneys, adjoining walls, skylights and other transitions also needs attention. Water can enter at these junctions where the flashing has pulled away.
Poor waterproofing is another easily missed issue. The roof surface can look acceptable while joints and seams are already failing.
Don’t climb onto the roof yourself. Where concerns arise, arrange a professional inspection.
Ask before you make an offer
Ask the seller about previous leaks, damp problems and roof repairs. Request available reports or warranties and find out whether repaired areas have stayed dry through subsequent rain.
