Bi-annual inspections, drainage, membrane upstands and the indicators that tell you a specialist survey is overdue.
Flat roofs on care home buildings carry a higher maintenance burden because of penetrations, higher foot traffic during maintenance, and continuous occupation that means any leak causes immediate disruption. The standard approach of wait-until-it-leaks is not acceptable in a care setting -- proactive inspection is the only viable strategy.
The recommended cycle is two inspections per year: a spring inspection (post-winter) to identify frost damage, split flashings, and winter debris blocking drainage; and an autumn inspection (pre-winter) to clear all drainage outlets and identify membrane deterioration before cold weather prevents repair. Insurance requirements frequently specify annual inspection -- treat this as the minimum floor.
The inspection must physically check: all drainage outlets (clear and free-flowing -- blocked outlets are the single most common cause of water ingress); membrane upstands at parapets (should extend at least 150mm above roof level); flashings at all junctions; penetrations for plant, pipes or services (sealed with purpose-made collars); and the membrane surface for blistering, cracking, ponding or vegetation growth.
A general maintenance inspection catches most obvious failures, but some conditions require specialist assessment: ponding water remaining more than 48 hours after rain; blistering or delamination across more than 10% of the area; or a roof more than 20 years old. A specialist condition survey (typically 400-1,000 for a standard care home roof) is negligible relative to the cost of emergency water ingress during occupation.
Log every inspection with: date, inspector's name, each element checked, any defects with photographs, remedial actions required and timescale, and date remediation was completed. An insurer processing a water ingress claim will ask for the inspection history -- a documented record separates a claim from a dispute.
