Your roof is the first line of defence against the elements, yet it is often the most neglected part of a property. Regular roof inspections can identify minor issues before they develop into major structural problems or cause water damage to the interior. This checklist guides you through a systematic roof inspection, covering everything from tiles and flashing to gutters and loft spaces, so you can maintain your roof's integrity year-round.
Why Roof Inspections Matter
A damaged or deteriorating roof can lead to water ingress, insulation failure, structural timber decay, and even mould growth within the living spaces below. Roof repairs caught early typically cost a fraction of what full replacements demand. For homeowners, a well-maintained roof also preserves property value and prevents insurance claim complications. For landlords and property managers, regular roof inspections are part of your duty of care to occupants. Scheduling inspections at least twice a year — ideally in spring and autumn — ensures seasonal weather damage is caught promptly.
The Complete Roof Inspection Checklist
Roof Covering and Tiles
The roof covering is the most visible component and the primary barrier against rain, wind, and snow. Damaged or displaced tiles create entry points for water that can cause extensive internal damage.
- Scan the entire roof surface for missing, cracked, slipped, or broken tiles and slates
- Check for moss, lichen, or algae growth that can trap moisture and accelerate deterioration
- Inspect tile bedding at verges and ridges for crumbling mortar or loose fixings
- Look for signs of previous patch repairs that may indicate recurring problems
Ridge and Hip Tiles
Ridge and hip tiles sit at the highest and most exposed points of the roof. They are particularly vulnerable to wind damage and mortar erosion over time.
- Check ridge tiles along the apex for loose mortar, gaps, or misalignment
- Inspect hip tiles for secure bedding and consistent alignment down the hip rafter
- Look for signs of dry ridge or hip systems that may have come loose at fixings
- Verify that ridge and hip tiles are continuous with no gaps that could allow water entry
Flashing and Seals
Flashing provides watertight seals at junctions where the roof meets walls, chimneys, dormers, and other projections. Failed flashing is one of the most common causes of roof leaks.
- Inspect lead flashing at chimney abutments for lifting, cracking, or corrosion
- Check stepped flashing where the roof meets a wall for gaps or deteriorating mortar
- Examine valley flashings or valley gutters for splits, blockages, or debris buildup
- Verify that all flashing is securely dressed into mortar joints and properly sealed
- Look for signs of previous silicone or sealant repairs that may need replacement
Gutters and Downpipes
The rainwater drainage system carries water safely away from the building. Blocked or damaged gutters cause water to overflow against walls, leading to damp penetration and foundation erosion.
- Clear gutters of leaves, moss, and debris and check for standing water that indicates poor fall
- Inspect gutter joints and brackets for leaks, sagging, or corrosion
- Check downpipes are securely fixed and discharging into drains rather than against walls
- Verify hopper heads and gutter outlets are clear and functioning correctly
Chimney Stacks and Pots
Chimney stacks are exposed to the worst weather conditions and deteriorate faster than most other parts of the roof. Structural movement in chimney stacks can be a serious safety concern.
- Check chimney stacks for leaning, cracked mortar joints, or spalling brickwork
- Inspect flaunching around chimney pots for cracks that could allow water penetration
- Verify chimney pots are secure and fitted with cowls or caps if the flue is not in use
- Look for staining on chimney brickwork that may indicate internal damp or condensation
Fascias, Soffits, and Bargeboards
These components provide the finished edge to the roofline and protect the roof timbers from weather exposure. Deterioration here can allow birds, insects, and moisture to enter the roof space.
- Inspect fascia boards for rot, peeling paint, warping, or insect damage
- Check soffits for holes, cracks, or dislodged ventilation grilles
- Examine bargeboards at gable ends for secure fixation and weather damage
- Verify that soffit ventilation is adequate and not blocked by insulation or debris
Loft Space Internal Inspection
The loft space provides a valuable internal view of the roof structure. Many roof problems reveal themselves inside the loft before they become visible externally.
- Look for daylight showing through the roof covering which indicates gaps or missing tiles
- Check roof timbers for signs of rot, woodworm, or structural movement
- Inspect the underside of the roof felt for tears, sagging, or condensation dripping
- Verify insulation is evenly distributed and not compressed, damp, or displaced
- Look for water staining on timbers or around penetrations such as soil vent pipes
Flat Roof Sections
If your property includes any flat roof sections such as extensions, bay windows, or dormers, these require specific attention as they are more prone to water pooling and membrane failure.
- Check the flat roof surface for blistering, cracking, splits, or ponding water
- Inspect upstands and edge trims for secure fixation and watertight seals
- Verify outlets and drainage channels are clear and water drains away efficiently
- Look for vegetation growth which can indicate trapped moisture beneath the surface
Best Practices for Roof Inspections
- Inspect your roof at least twice a year and after any severe weather events
- Use binoculars for a ground-level survey before considering ladder or scaffold access
- Never walk on a roof unless you have appropriate safety equipment and experience
- Photograph all findings with date stamps for your maintenance records
- Address small repairs promptly to prevent them escalating into costly major works
- Engage a qualified roofer for any repairs involving working at height or structural elements
How Checksheets Helps
Checksheets provides a dedicated digital checklist for roof inspections that you can complete from the ground, on a ladder, or from within the loft space using your mobile device. Capture photographs of problem areas and attach them directly to the relevant checklist item. Rate each element from satisfactory to urgent and generate a prioritised maintenance report. Store your roof inspection history on the platform so you can track deterioration over time and plan repairs proactively. For property managers with multiple buildings, Checksheets gives you a centralised view of roof conditions across your entire portfolio, helping you allocate maintenance budgets effectively.
Do not wait for a leak to tell you there is a problem. Regular roof inspections save money, prevent damage, and extend the life of your roof. Start your free checklist today and keep your property protected from the top down.
