Owners around St Mellons, Old St Mellons and Castleton often ask whether their roof has years left or is on borrowed time. The honest answer depends on materials, exposure and what has been done to it before. You can gather useful clues without leaving the ground, and a survey then turns those clues into a straight recommendation.

What you can see from the ground

Stand back across the road or in the garden and look along the slopes. Sagging ridge lines, patches where tiles have slipped, missing pieces, heavy moss and tiles with a rough, bleached surface all tell a story. Check gutters for gritty granules or tile fragments and look at the fascia line for stains or overflow marks. Please do not climb a ladder or step onto the roof to look closer; ring us for a survey instead.

What the loft tells you

The loft is often more revealing than the outside. With a torch from the hatch, look for daylight through the roof, dark patches on timber, damp insulation and drips. Felt that has split or hangs loose between rafters points to a covering at the end of its working life. Also watch for condensation on the underside of the roof after cold nights, which signals poor airflow rather than a leak, though the two can look alike.

Age, material and exposure

A roof of slate behaves very differently from concrete or clay. Good slate can outlast its fixings, concrete tiles tend to suffer in the surface, and older felt perishes regardless of the tile above. Open ground on the edge of Cardiff takes more wind and driven rain than sheltered streets, which speeds up wear on ridges, verges and fixings. Previous repairs matter too, since patched areas often fail again beside the patch.

What a proper survey checks

When we survey, we look at the whole system, not only the covering: battens, felt, flashings, ridge, verges, valleys, gutters and the roof edge. We note which faults are local and which are widespread. You get a plain recommendation with the reasons behind it, not a sales pitch. We also photograph what we find where we can, so you can see the same things we saw rather than taking our word for it.

Repair now, or plan a replacement?

A roof with a few isolated faults and sound underlay is a good candidate for repair. One with repeated leaks, failing felt or widespread tile damage is not. Delaying a necessary re-roof usually means timber damage, which makes the eventual job larger. If you are unsure, call us and we will survey it and tell you honestly where it stands.
