Roof Repair or Replace?
Fix it, renew the covering, or replace the whole roof? Answer five questions for an indicative steer and the reasoning behind it. This is a starting frame, not a verdict — a leaking or ageing roof should be assessed on site by a licensed contractor, and any structural sign by a structural engineer.
Typical service life of a rcc flat roof: ~45 years.
- Patch-repairing is no longer the economical answer — the covering or waterproofing layer is near the end of its service life.
- Renewing the whole layer (not another patch over a stain) is where the money is well spent.
- Get 2-3 like-for-like quotes and fix any drainage/slope faults at the same time.
An indicative steer only. A real repair-or-replace decision needs an on-site inspection of the covering, the drainage, the junctions and the structure — things this quick tool cannot see. Use it to frame the conversation, then get a licensed roofing contractor’s assessment (and a structural engineer’s if there is any sign of sagging, spalling or movement). Working at height is dangerous — never inspect a wet, sloping or fragile roof yourself.
