Managing multiple properties means roofs can be a constant concern. This practical roof repair checklist is written for UK property managers, landlords and facilities teams who need a clear, repeatable process for spotting issues, commissioning repairs and keeping costs under control.
1. Initial visual inspection (external)
Start with a quick external walkaround to identify obvious problems before arranging more detailed work. Carry out these checks after heavy weather and at least twice a year.
- Look for missing, cracked or slipped tiles or slates — these are the most common causes of leaks.
- Check flashings and chimneys for gaps, rust or deteriorated mortar where leaks often start.
- Inspect gutters and downpipes for blockages, sagging or split joints that cause water to back up under the roof covering.
- Note any moss, lichen or algae growth — excessive moss traps moisture and shortens the life of tiles and slates.
- Assess roofline and fascia/soffits for rot, pest damage or detached sections.
2. Safety and access considerations
Roof work carries inherent risk. Confirm safe access and any site-specific hazards before allowing tradespeople on site.
- Risk assessment — identify live electrical lines, fragile roof areas and overhead obstructions.
- Scaffold or edge protection — ensure appropriate fall protection for pitched roofs; use harnesses where scaffold isn’t possible.
- Clear working area — remove vehicles and valuables from the drop zone beneath the roof work.
- Tenant safety — notify occupants of noisy or intrusive work and secure communal areas during repairs.
3. Leak detection and documenting damage
When you suspect a leak, follow a diagnostic process so repairs target the root cause rather than symptoms.
- Locate internal signs — water stains, damp patches, peeling paint and mould on ceilings and walls.
- Perform controlled water tests (roofers can do this) to identify the leak path on complex roofs or flat sections.
- Use drone or harness inspections for accurate photos of high or unsafe roofs — many professional teams offer drone roof inspections to speed up diagnosis.
- Record everything — timestamped photos, notes on weather conditions, and any temporary measures used to limit damage.
4. Common repairs and prioritisation
Not all defects require immediate full replacement. Use this prioritisation to decide urgent vs planned work.
- Urgent (same-day to 72 hours): active leaks, collapsed gutters, large areas of missing covering, storm damage exposing the structure.
- High priority (weeks): failing flashings, cracked valley/gutter linings, significant moss build-up, damaged insulation causing damp.
- Planned maintenance (months): minor slipped tiles, general moss removal and roof cleaning, re-pointing ridge mortar, routine roof coating reapplication.
- Repair types to consider: tile/slate replacement, flashing repairs, ridge re-bedding, gutter repair, flat-roof patching or membrane replacement, EPDM or GRP repairs for non-pitched areas.
5. Materials, durability and warranties
Choose materials that suit the building, budget and expected lifespan. Document manufacturer names and warranties for future reference.
- Match materials — replace like-for-like where possible to maintain performance and appearance (e.g. slate for slate, tiles for tiles).
- Consider weather resistance — use wind-resistant fixings and UV-stable membranes for exposed locations.
- Ask about guarantees — reputable roofing companies provide workmanship guarantees and details of material warranties.
- Energy and insulation — where work exposes the loft or roof void, consider adding insulation or improving ventilation to reduce long-term energy costs.
6. Tendering and choosing contractors
When repairs go beyond minor fixes, obtain competitive quotes and ensure contractors meet standards.
- Request at least three written quotes with clear scope, materials, timescales and payment terms.
- Check local experience — local roofers understand regional wind and rain patterns; Roofing, Roofers and Roofs works with skilled tradespeople across the UK to deliver tailored solutions.
- Verify references and past projects and, if relevant, inspect completed work in person or via recent case studies.
- Insurances and compliance — confirm public liability and employers’ liability cover and that the contractor will comply with health and safety regulations.
7. Post-repair checks and ongoing maintenance
After repairs finish, confirm the job meets the brief and schedule regular upkeep to avoid repeat issues.
- Final inspection — walk the site with the contractor and check that flashings, gutters and fixings are secure and water runs freely.
- Document completion — retain photos, receipts, warranties and maintenance recommendations in your asset management records.
- Set a maintenance calendar — plan biannual inspections, gutter clearing and moss removal; consider an annual roof survey from a professional team.
- Emergency plans — ensure tenants know who to contact for leaks and that you have an emergency call-out arrangement in place for storms or sudden failures.
