Much of Harrow was built in one rush between the wars. The Metropolitan line opened up the fields around Rayners Lane, North Harrow and Kenton, and builders filled them with semis that share a recognisable roof: hipped, covered in clay or concrete plain tiles, with a tile-hung gable over the front bay. Stanmore and Harrow Weald added larger detached houses on the same theme, and there are whole streets of bungalows in Kenton and Belmont. Older Harrow survives on the Hill around the school, in Pinner's High Street with its timber-framed and brick buildings, and in parts of Wealdstone and Greenhill, where Victorian terraces carry slate. Behind almost every house now sits a kitchen extension or garage with its own flat roof.

On a Metroland semi the classic faults arrive together. The original tiles are porous and flaking, the hips are bedded in mortar that has cracked and fallen out, and the tile-hung bay gable lets water into the bay ceiling once a few tiles go. The neighbour's half of the roof has often been replaced already, so the junction down the party wall needs proper detailing, not a smear of mortar. Bungalows suffer at the valleys and around later roof windows. Flat roofs on the back extensions blister, crack at the upstands and pond where the fall was never right. We repair tiles and hips, rebuild bay roofs, re-roof whole houses with dry ridge and hip systems, lay EPDM and GRP and repoint, rebuild or remove chimneys.

Harrow on the Hill, Pinner and Stanmore have conservation areas, and on those streets we match the original tile and detail and talk through any consent with you before work is booked. Everywhere in the borough the process is the same: you ring 07429 820474 or send the form, Thomas comes out, gets up to the roof and explains what he found, and you get a fixed written price with nothing added later. The family carries out the work, clears the site every day and hands over a 10 year guarantee on every new re-roof. We look after homeowners, landlords with houses split into flats and shops on the parades, Monday to Saturday, 8am to 6pm.

Harrow questions

Next door has already re-roofed our Rayners Lane semi. Is that a problem?

No. We re-roof your half and detail the junction at the party wall so the two roofs meet cleanly and stay watertight. We match the tile colour as closely as the market allows and show you samples before you agree.

Why is the ceiling in my front bay damp?

On Harrow's inter-war semis the bay has its own small roof and tile-hung gable. Slipped tiles, a failed flashing against the main wall or a rotten bay roof deck will all show up in that ceiling. We open it up, find which it is and price the repair in writing.

Do you work on bungalows in Kenton and Belmont?

Yes. Bungalow roofs are everyday work for us: tile and valley repairs, roof windows flashed properly, full re-roofs and dormer flat roofs. The visit and the quote are free.
