Most roofing problems are visible before they cause serious damage - if you know what to look for. This guide covers what an Inverness homeowner can reasonably check from ground level, what signs indicate a professional inspection is needed, and what never to do when inspecting a roof.
The vast majority of roof assessment that matters can be done from the ground with binoculars. Getting on a roof without training, correct equipment and experience is genuinely dangerous and unnecessary for a homeowner assessment. Here is what to check from ground level:
Walk slowly around the full perimeter of the property, looking up at each roof slope. You are looking for: missing tiles or slates (obvious gaps in the pattern); displaced tiles that have slipped out of alignment; cracked tiles (visible as a dark line across the tile face); and curling or lifted slates on older properties. On a typical Inverness property, a few displaced tiles is a minor repair. More than 10–15% of tiles showing movement or damage on a single slope suggests a systemic issue - nail sickness on older concrete tile properties, or deteriorating mortar bed on clay tile roofs.
The ridge - the line along the highest point of the roof - is often the first area to show mortar failure. Look for missing or sunken ridge tiles (the mortar bed underneath has failed), tilted or displaced ridge tiles, and any open gaps along the ridge line. Hips - the angled junctions on hipped roofs - are subject to the same mortar failure. In Inverness, ridge mortar checks are most important in spring after the frost season has passed.
Check all four faces of the chimney stack. Look for: pointing that is recessed, cracked or missing (mortar erosion); leaning or tilting of the stack; loose or missing chimney pots; lead flashing at the base of the stack that is lifted, cracked or missing. Lead flashing failure is the most common cause of chimney-area leaks in Inverness properties. A correctly flashed chimney should show lead dressed tightly against the brickwork with no visible gaps.
Check gutters for visible sagging, overflow staining on the fascia below, and debris accumulation. Valleys - the internal angles where two roof slopes meet - are best checked from ground level after heavy rain. Water tracking down the inside of a wall below a valley is a valley failure. In Inverness, valley blockage from leaf debris is the most common autumn cause of leak calls.
If you have loft access, a torch inspection on a dry day reveals a great deal:
Always call a professional roofer if you identify any of the following from your ground-level or loft inspection:
A professional inspection costs £95–£150 for a standalone assessment. In every case above, identifying the issue early is substantially cheaper than allowing it to progress to structural damage or internal water ingress.
Do not attempt to walk on your roof. Falls from domestic roofs are a leading cause of serious DIY injury in the UK. Even on a low-pitch roof, wet tiles are extremely slippery and roof surfaces are not designed to support a standing person without proper equipment. If you need closer access to inspect or repair, call a professional roofer.
Do not use a ladder to inspect the roof surface unless you have had ladder safety training and the ladder is correctly footed and secured. Binoculars from ground level provide a safe and adequate assessment for most purposes.
If your ground-level inspection has identified concerns, or if you would simply like a professional condition report on your Inverness property, call 01463 262835. We carry out free surveys on any roofing project over £300, and standalone surveys from £95 for pre-purchase or condition assessment purposes.
📞 Call: 01463 262835| Month | What to Check | Why |
|---|---|---|
| September | Ridge mortar, valley condition, gutter clearance | Before the Highland frost and storm season |
| November | Gutter blockage, valley debris after leaf fall | Leaf fall blocks valleys - causes most autumn leak calls |
| March/April | Ridge and hip mortar, any tiles dislodged by frost | Post-frost season assessment |
| Any time after storm | Full ground-level visual, loft check | Storm events dislodge tiles and lift flashings |
Whatever the roofing question, the right starting point is a professional survey carried out by a roofer who knows Highland conditions and the local housing stock. A survey costs nothing when combined with any roofing project, and £95–£150 as a standalone assessment. The written condition report that follows gives you a clear picture of the current state of your roof, what needs to happen and in what sequence, and what the costs will be.

No - for a homeowner without training and proper equipment, walking on a roof is dangerous and unnecessary. A ground-level inspection with binoculars covers most of what matters. If you need a close inspection, call a professional roofer. Falls from domestic roofs cause serious injuries every year.
A brief ground-level check twice a year - September before winter and April after the frost season - covers the main risk periods for Highland properties. Always carry out a visual check after any significant storm or prolonged heavy rainfall.
Nail sickness is difficult to identify from ground level in its early stages - the tiles remain in position even as the nails corrode. From loft level, rust staining on sarking boards below tile courses is the clearest indicator. In advanced cases, tiles may begin to slip individually. If your property has concrete tile roofing from the 1970s–1980s and has never been surveyed, a professional inspection is recommended.
From outside: blistering or bubbling of the membrane surface, visible ponding water that remains 48 hours after rainfall, obvious cracks or open joints in the membrane or upstands. From inside: water staining on the ceiling below the flat roof section. Any of these indicate the flat roof needs professional attention.
Call 01463 262835 immediately - we provide 24/7 emergency roofing response across Inverness and Highland.
