Roofers in Brent who actually turn up.

What Brent roofs go wrong with, and what it costs

Brent is one of London's most varied boroughs, stretching from the dense terraces around Harlesden and Kilburn to the leafier suburban streets of Kenton and Queensbury. Roofs here cover everything from Victorian slate to interwar tile and postwar council stock, and many have had patch repairs rather than a proper overhaul. The result is a mix of ageing slate, worn clay tile, and flat roof extensions that tend to fail at different times and for different reasons.

The houses

In areas like Kilburn, Willesden, and Harlesden, you find a lot of Victorian and Edwardian terraced housing with pitched slate roofs and shared party walls. These roofs often have original slate that has lasted well over a century but is now reaching the point where slipped or cracked slates are common, especially where earlier repairs used mismatched materials. Chimneys on these terraces are frequently shared between neighbouring properties, so any chimney repointing or flashing work needs coordination with next door.

Move further out to Kenton, Queensbury, and parts of Wembley, and the housing shifts to interwar semis and detached houses with clay tile roofs, along with a good number of postwar council-built blocks and maisonettes with flat roof sections. The semis typically have simple gable roofs that hold up well but develop ridge tile and valley problems as pointing and seals age. Flat roofed extensions and garages, common across the borough's newer housing, are usually felt or GRP (fibreglass) roofs that need resealing or full replacement after years of weather exposure depending on how well they were installed.

The jobs we see most

• Slate and tile repairs Replacing slipped, cracked, or missing slates and tiles on Victorian and interwar roofs across streets in Kilburn, Harlesden, and Kenton, matching the existing material where possible.
• Chimney repointing and flashing Repointing shared chimneys on terraced housing and renewing lead flashing where it meets the roofline, a common source of damp in older Brent terraces.
• Flat roof repairs and recovers Resealing or replacing felt and GRP flat roofs on extensions, garages, and some postwar blocks, which tend to need attention more often than pitched roofs.
• Guttering and fascia replacement Clearing and replacing worn guttering and fascia boards, particularly on semis in Queensbury and Wembley where original fittings have reached the end of their life.
• Full roof replacements Stripping back and renewing roofs that have had years of patch repairs, usually on older terraced housing where the underlying structure and timbers also need a check.

Conservation areas and listed buildings

Much of inner London sits within conservation areas, and parts of Brent are no exception, particularly around some of the borough's older residential streets. Where a property falls within one of these areas, roofing work may need to use like-for-like materials such as matching slate or clay tile rather than cheaper modern alternatives, and some changes can require planning permission. The council's planning team can confirm whether a specific property is affected and what restrictions apply before any work starts.

One local tip

If you live in one of Brent's older terraces, get your roof checked after any long spell of heavy rain or strong wind, since shared chimneys and party wall junctions are often where small leaks start long before they show up inside the house.
