How long should a roof last?
Why lifespan varies so much between slate, tile and flat roofs — and how to get the most from yours.
Material matters
Natural slate is among the longest-lasting coverings, though the nails holding it often fail first. Concrete tiles and flat roof membranes generally have shorter lives.
Installation and detailing
A well-installed roof with good flashings and ventilation lasts far longer than the same material fitted poorly.
Maintenance
Clearing gutters and replacing the odd slipped slate early prevents small problems turning into big ones.
Know where you stand
A roof inspection tells you the condition of your roof now and what to plan for.
