When to Replace Rather Than Repair in Harrow
If your Harrow roof has multiple problem areas, persistent leaks that recur after repair, or tiles that are over 60 years old and becoming porous, full replacement often makes more financial sense than ongoing piecemeal repairs. A new roof typically pays for itself through eliminated repair costs and improved energy efficiency within 10-15 years.
Other signs that replacement is needed include visible sagging in the roofline (indicating structural timber issues), widespread moss growth that returns quickly after treatment, and more than 20% of tiles showing cracks or damage. We'll always give you an honest assessment — if repair is the better option, we'll tell you.
