Honest advice
Do You Actually Need Flat Roof Repairs?
When a Shelton Lock roof starts giving trouble, the symptoms point the way. A leaking flat roof in Derby is often repairable — the trick is telling a localised failure from a covering that has reached the end of its life. We assess honestly and repair where a repair genuinely holds. On Shelton Lock roofs the warning signs tend to come early, because shelton lock sits by the derwent and canal, with valley humidity accelerating moss on shaded roofs, so it pays to act promptly here.
Any of these is worth a call:
A single split, blister or lifted lap in otherwise sound felt
Failed mastic around a rooflight or pipe penetration
A leak that traces to one detail — an upstand, outlet or junction
When it is not the answer: If the deck is wet and soft or the covering is failing in several places at once, patching is throwing money at a roof that needs re-covering Read the full guide.
