Angel, Central London roofing work
A finished slate and leadwork roof in Angel
This Angel roof replacement shows how the finish of a period London roof depends on more than the slates alone. Leadwork, parapets, gullies and ridge details all have to work together to keep the building weather-tight.
The finished project uses Canadian Glendyone slates with Code 5 lead flashings. The project description also records capped parapets, welded lead gullies and lime mortar ridge details.
The lead gullies and parapet cappings are particularly important because they handle water at the roof edges and junctions. If those details fail, a roof can leak even when the main slate covering still looks sound.
Those details are especially relevant on older London properties, where the replacement needs to protect the building without losing the character of the roof. The right materials and detailing depend on the property and should be confirmed during an inspection.
