A newer house gives the roof an easier life than an old cottage, because the structure is sound, the pitch is usually adequate and the covering has had little time to wear. Faults still happen, and when they do they follow a short list that we know well.
Q2.1Why do tiles move?
A tile can slip when a clip fails or a batten is poorly nailed, and strong wind then does the rest. One missing tile is a tiny job, but it leaves the underlay exposed to light and rain, so it is worth acting promptly. Our slipped roof tiles page explains what we look for and when a single tile is enough.
Q2.2What fails at ridges and junctions?
Where two roof planes meet, or a slope butts against a wall, a sealed joint carries the load. Sealant ages, lead moves, and a tight valley can overflow in a heavy shower. We re-form the joint with the right metal or board instead of smearing sealant over a gap, since a smear tends to fail again within a season or two.
Q2.3Do the roofline and gutters need replacing?
The boards and gutters at the eaves are plastic on many newer homes. They need clearing, re-aligning and sometimes replacing, though seldom more than that early in a house's life. Spillage at a single corner usually points to a tilt or a blockage, so a full replacement is rarely the first answer. Clearing the run, checking the falls and refitting any loose bracket often cures it.
