The window between tenancies — typically 2–6 weeks in East London — is the only time you have unrestricted access to the property without tenant disruption. Use it. A roof maintenance visit during voids prevents emergency call-outs during tenancies, protects your compliance position, and preserves the property's condition for the next letting.
Most landlords focus void periods on painting, cleaning, and cosmetic updates. The roof is invisible and easy to forget — until a new tenant reports a leak in their first week. That call costs you an emergency repair, tenant goodwill, and potentially a fitness-for-habitation challenge.
Tiles and slates: Look for gaps in the roof covering with binoculars. Slipped slates appear as darker lines where the underlay is exposed. Cracked or missing tiles show as bright patches against the aged covering.
Ridge tiles: Check that ridge tiles are aligned and firmly bedded. Rocking or displaced ridges let water straight into the roof structure. Mortar-bedded ridges erode every 15–20 years — dry ridge systems are the permanent replacement.
Flashings: Look at the junction between the roof and chimneys, walls, and dormers. Lifted lead, cracked mortar fillets, or gaps indicate flashing failure — the number one cause of persistent leaks.
Gutters and downpipes: During rain, watch the guttering. Overflows indicate blockages. Drips at joints indicate seal failure. Water running down the wall below a downpipe indicates a broken section. Clear all gutters of debris and test the flow.
Fascias and soffits: Press timber fascias with your thumb. Softness means rot. Check soffit ventilation strips are clear — paint, dirt, and insect debris block them.
Daylight: In the loft during daytime, look for pinpoints of light through the covering. Each point of light is a potential water entry point.
Water staining: Dark marks on rafters and purlins indicate past or active leaks. Fresh staining is darker and damp to touch.
Insulation: Check insulation is evenly distributed and not compressed, displaced, or soaked. Wet insulation is heavy and dark — a sign of an active leak above.
Ventilation: Feel for airflow at the eaves. Blocked eaves cause condensation — the "leak with no hole." If insulation is stuffed into the eaves space, pull it back to restore airflow.
Timber condition: Probe exposed timbers with a bradawl. Softness indicates rot. Look for bore dust (woodworm) — small piles of fine powder below timber surfaces.
Victorian terraces (Hackney, Bow, Bethnal Green): Check for slipped slates (nail sickness), chimney flashing condition, valley integrity, gutter clearance, and loft ventilation. Allow £150–£500 for typical maintenance repairs.
1930s semis (Ilford, Romford): Check concrete tile porosity, hip iron condition, valley mortar, ridge bedding, and flat roof extensions. Allow £150–£600.
Post-war estates (Barking, Dagenham): Check flat roof membrane condition, drainage outlets, parapet copings, and asphalt condition on walkways. Allow £200–£800.
The checklist above covers what you can assess from ground level and the loft hatch. For a thorough inspection including the roof surface itself, call a professional. Our void-period inspection costs £120–£250 and covers all of the above plus a detailed written report with photographs. The fee is credited against any repair work you book.
Schedule the inspection at the start of the void period so any repairs can be completed before the new tenant moves in.

A void-period roof inspection costs £120–£250 and typically identifies £150–£500 of maintenance repairs. Total: £270–£750 for a comprehensive check and fix. Compare that to an emergency call-out during a tenancy: £180–£400 for make-safe alone, plus the permanent repair, plus tenant disruption, potential temporary accommodation, damp remediation, and the compliance documentation you should have had but did not.
The void-period maintenance approach costs less, prevents tenant complaints, protects your compliance position, and preserves the property’s condition. It is the single most cost-effective maintenance strategy a landlord can adopt.
Spring (March–April): Ideal for post-winter checks. Look for storm damage, frost-cracked tiles, and mortar erosion from winter weather cycles. Clear gutters of winter debris.
Summer (June–August): Best conditions for major work. Re-roofing, flat roof replacement, and chimney work all benefit from dry, warm conditions. If a void period falls in summer and the roof needs significant work, this is the optimal time.
Autumn (September–November): Critical gutter clearance period. Heavy leaf fall from London planes, oaks, and maples blocks gutters across East London — especially in Walthamstow, Woodford, and Chingford near Epping Forest. Clear gutters after the main leaf fall in late October.
Winter (December–February): Emergency response only. Avoid planned work in freezing conditions — mortar does not cure, adhesives fail, and wet surfaces are hazardous. Focus on internal loft inspections and documenting any condensation problems.
Every void-period inspection should produce: dated photographs of the roof exterior, loft space, and guttering condition, a written condition report grading each element, an estimate for any recommended repairs, and a completion certificate for any work carried out. Keep these with the property file — they demonstrate ongoing maintenance responsibility and provide a defence against any future fitness-for-habitation claim.
Our inspection reports are formatted specifically for landlord records and include all of the above elements. They are also useful for letting agents who need to demonstrate property condition to prospective tenants.
If you manage multiple East London properties, we offer a portfolio maintenance package. We schedule void-period inspections across your properties as tenancies change, maintaining a central record of roof condition for each property. This proactive approach identifies work that can be batched (e.g. booking scaffold for adjacent properties simultaneously), reducing per-property costs and ensuring nothing is missed.
Void periods are also the right time for planned upgrades that are difficult or disruptive during a tenancy. Upgrading loft insulation from 100mm to 270mm (Building Regulations standard) costs £300–£600 and significantly reduces the next tenant’s heating bills — making the property more attractive and reducing the risk of condensation complaints.
Replacing mortar-bedded ridge tiles with a dry ridge system costs £400–£900 and eliminates the most common source of periodic maintenance calls. Replacing failing felt flat roofs on rear extensions with GRP (£80–£105/m²) during a void prevents the "new tenant, first week, first leak" scenario that damages landlord-tenant relationships from day one.
Victorian terraces (Hackney, Bow, E2–E9): Slipped slates (2–5 per year per slope from nail sickness), chimney flashing separating from mortar, blocked cast iron gutters with vegetation growing in the joints. Average maintenance cost: £250–£500 per void.
1930s semis (Ilford, Romford, IG1–IG3, RM1–RM7): Porous concrete tiles on the weather face, eroded ridge mortar, corroded hip irons, and flat roof extensions with bubbling felt. Average maintenance cost: £200–£600 per void.
Post-war estates (Barking, Dagenham, RM8–RM10): Flat roof drainage blockages, parapet coping displacement, loft insulation gaps, and soffit ventilation blocked by old insulation or paint. Average maintenance cost: £150–£450 per void.
HMOs (Stratford, East Ham, E6–E15): Enhanced condensation risk from higher occupancy, multiple flue penetrations from individual boiler installations, loft conversion fire-rating checks. Average maintenance cost: £200–£700 per void.
Book early. Contact us as soon as you know the void dates. Same-week appointments are available but 1–2 weeks’ notice ensures your preferred date.
Combine with other trades. If you are also having the property cleaned, painted, or refurbished during the void, schedule the roof inspection first. If we find work that involves scaffold, the scaffold can be shared with painters or window cleaners, reducing per-trade costs.
Keep the report. File our inspection report with the tenancy documents. The incoming tenant’s check-in inventory should note the roof condition assessment date. This protects you against any claim that pre-existing problems were present at the start of the tenancy.
Even during void periods, roofs can develop problems — storms, vandalism, or accelerated deterioration on already-weak elements. Ensure your emergency roofer contact is logged with the letting agent, any property guardians, and building management (for flats). Our 24/7 emergency line (0203 441 9626) covers void properties across all East London postcodes. Emergency make-safe costs £180–£400 and prevents minor storm damage from becoming major water ingress into an unoccupied property where no one is there to catch it early.
A void-period roof inspection is the single most cost-effective maintenance action a landlord can take. It prevents emergency repairs, protects your compliance position, preserves property value, and ensures the next tenant moves into a weathertight home. At £120–£250 — credited against any repair work — it is effectively free insurance.
