When does replacement make more sense than repairs?
When does replacement make more sense than repairs?
The crossover point is typically when repair costs would exceed 35–40% of full replacement cost, or when the roof is over 30 years old and showing widespread issues. Nail sickness on Shrewsbury’s 1960s concrete tile estates is a clear example — once 20–30% of tiles are affected, a full nail-and-re-fix with new underlay is the economical choice over ongoing individual repairs.
Materials and specifications for Shrewsbury housing stock
For Victorian and Edwardian properties in Belle Vue, Monkmoor and the town centre, reclaimed Welsh slate or clay plain tile is the correct specification. For the 1930s semis of Meole Brace and Copthorne, concrete plain tile or modern clay offers excellent performance. For post-war and 1960s estates in Harlescott and Sundorne, high-quality concrete interlocking tile with breathable underlay is the standard recommendation.
