Signs your roof needs attention — a checklist

The clearest signs your roof needs attention are slipped, cracked or missing slates, sagging in the roofline, damaged flashing or guttering, and any damp, daylight or staining visible from inside the loft. Spotting one or more of these early is the difference between a quick repair and a large bill, so it pays to know what to look for.

Your roof is doing more than keeping the rain off. It holds the structure of the building together and takes the full force of Scottish weather, year in, year out.

Most of these checks you can do from the ground or, where it is safe, from inside the loft. Only ever use a ladder if you are genuinely competent and confident doing so, and never put yourself on the roof itself. When in doubt, leave it to someone with the right access equipment.

Here is what to keep an eye on.

Quick checklist

• Slipped, cracked or missing slates and tiles
• Sagging or dips in the roofline
• Loose guttering or bits of slate washed into it
• Cracked, lifted or corroded flashing around chimneys and walls
• Blocked or clogged soffits and roof vents
• Daylight visible through the roof from inside the loft
• Damp, pooling water or a musty smell in the loft
• Water stains on the rafters or on upstairs ceilings

Tick off even one of these and it is worth a closer look. Several together usually means it is time to call a roofer.

Outside the house

Slipped, cracked or missing slates and tiles

The most common and most obvious sign. Scan the roof and note anything that has slipped out of line, cracked, split or gone altogether. Each gap is a way in for water, so missing or broken slates should be replaced promptly. After a storm is the time to look — high winds are what lift them.

Sagging or dips in the roofline

A roof should run in clean, straight lines. If you can see a dip, a sag or any waviness in the structure, that points to a problem underneath — often water-damaged timber or a failing support. This one is not a wait-and-see; call a roofer before it worsens.

Damaged or loose guttering

Check the gutters for broken bits of slate or tile that have washed down and lodged there, which is a clue that the roof is shedding material. Gutters that have come loose from the fascia suggest deterioration or the strain of repeated blockages. Both want sorting before they pull away entirely — our gutter maintenance guide covers keeping them clear.

Failed flashing

Flashing is the metal that seals the joins around chimneys, vents and where the roof meets a wall. When it cracks, lifts or corrodes, water gets straight in at exactly the points that are hardest to keep dry. Damaged flashing needs replacing rather than patching, and on older Edinburgh properties this is usually leadwork.

Blocked or clogged soffits and vents

The soffits and roof vents let the roof space breathe. When they clog up, airflow stops, damp builds, and the whole roof suffers from poor ventilation. Cracked vents also let the warmth out and push up your heating bills. Keep them clear and check for cracks.

Inside the loft

Daylight coming through

Pick a bright day and look up from inside the roof space with the light off. If you can see daylight through gaps or holes, water is getting in at those same points. Stand only on the joists, never the insulation or the ceiling below.

Damp, pooling or mould

Unexpected moisture, small pools of water or a musty smell in the loft all point to a leak. Even if you cannot see water, mould and a damp odour mean moisture is finding its way in from somewhere.

Water stains on the timbers

Watch for marks on the rafters and around the nails poking through from the slates. Condensation gathers on cold metal nails and drips onto the wood beneath, and over time that quietly rots the timber. It is a slow problem, which is exactly why it is worth catching early.

Stained or bulging ceilings

Brown or yellow marks on an upstairs ceiling usually mean water has tracked down from a leak above. Left alone it leads to mould, and in the worst case the ceiling itself can give way. If you find a stain, treat it as a leak until proven otherwise — our guide on what to do when your roof is leaking walks through the immediate steps.

How old is your roof?

A roof’s lifespan depends heavily on the material. A natural slate roof, properly maintained, lasts a great deal longer than a concrete tile one — we go into the detail in our guide on slate roof lifespan in Scotland. Whatever you have, an older roof benefits from a regular health check so small faults are spotted before they let water in.

What to do next

If you have ticked off one or two of these and want a professional eye on it, a proper inspection is the sensible next step. A well-maintained roof is a well-protected home. If you already have water coming in, read what to do when your roof is leaking first.
