What is a pitched roof?
A pitched roof features a sloped design that efficiently sheds rainwater. It is the most common roof type across London's residential and period properties, typically constructed in slate, clay tile, concrete tile, or occasionally metal. Pitches of 20° or above are considered 'pitched' under BS 5534 standards.
How long does a pitched roof last?
With materials like Welsh slate or clay tile, a pitched roof can last 75–100 years or more with correct installation and bi-annual maintenance. Concrete tiles typically last 40–60 years. Regular inspections prevent small issues — such as cracked tiles or failed flashing — from causing structural water ingress.
How do I know if my pitched roof needs repair?
Common signs include missing or slipped tiles, damp patches on ceilings or walls, visible daylight through the loft, moss or algae growth, and damaged or lifting ridge tiles. If you notice any of these signs on your London property, book a free roof survey with Knights Roofing for a professional assessment.

How long does a pitched roof repair take?

What is pitched roof maintenance and do I need it?
Pitched roof maintenance involves bi-annual inspections, moss and lichen removal, re-bedding or repointing of ridge tiles, checking and replacing failed flashing, and clearing valley gutters. For London properties, we recommend an inspection every two years. Early maintenance typically costs £150–£300 and can prevent repair bills of several thousand pounds.
Why are pitched roofs popular in London?
Pitched roofs offer superior rainwater drainage — important in London's climate — and a lifespan significantly longer than flat roofs. They suit the architectural character of Victorian and Edwardian properties that make up the majority of residential stock across South West and West London. They also allow for loft conversion, adding usable space and property value.
