Experienced With Northolt Homes
Much of Northolt was built between the 1930s and the 1960s. We know the hipped tile roofs, low-pitched estate roofs and flat-roofed extensions common across UB5.
Roof Repairs Northolt: What's Included
From a single slipped tile to a full re-roof, our professional roofing team covers every job across UB5.
Trusted Roof Repairs
Whether it is slipped tiles, cracked ridge pointing, failing lead valleys and broken ridge caps. Most repairs in Northolt are completed within 24 to 48 hours of your call.
Emergency Roof Repair
Whether it is storm damage, sudden leaks, or a fallen chimney stack — we make the roof safe and weatherproof quickly, then return to finish the full repair.
Flat Roof Repair & Replacement
As you might expect, Many Northolt homes have flat-roofed rear extensions, garages and dormers. In particular, we fit GRP fibreglass (seamless and hard-wearing), EPDM rubber (good for bay roofs and dormers) and torch-on felt for larger, budget-conscious areas.
New Roof Installation
Essentially, full strip-and-reroof to NFRC industry standards, in clay, concrete, natural slate or synthetic slate. Importantly, every new roof includes a written specification and a signed 10-year guarantee.
Chimney Repairs
Understandably, Many of Northolt's interwar semis still have their original chimney stacks, and these need regular attention — repointing, flaunching repair, Lead Sheet Association standard soaker replacement, pot removal and full stack rebuilds.
Guttering, Fascias & Soffits
This includes UPVC, aluminium and cast iron gutter replacement, downpipe re-routing and fascia renewal. In most cases, guttering jobs across UB5 are finished in a single day.
Soffit & Fascia Renewal
Fascia and soffit board replacement on older Northolt properties, including safe removal of asbestos-containing boards in line with HSE asbestos guidance, carried out through licensed waste carriers.

Experienced Roof Repairs for Every Northolt Property Type
Northolt's homes range from 1930s semis to post-war estate houses and maisonettes, so we approach each roof differently.
Northolt Housing Stock
Northolt grew quickly from the 1930s, and much of its housing dates from then or from the estates built after the war, including the Racecourse Estate on the site of the old Northolt Park racecourse. Interwar semis usually have hipped roofs in clay or concrete tiles, while many post-war houses and maisonettes have shallow-pitched or flat roofs. Typical faults are slipped tiles and worn ridges on the older pitched roofs, and splits, blisters and ponding on flat roofs. Northolt Village Green is a conservation area, so we check with Ealing Council before changing roof materials there.
Fast Local Response
Based 10 to 15 minutes from Northolt, we can usually reach an emergency within 2 to 4 hours, any day of the week.
What This Means For Your Roof
In practice, most of our Northolt call-outs are flat roof leaks on extensions and garages, slipped tiles after high winds, and blocked or leaking gutters. If you own a former council maisonette, check whether the freeholder is responsible for the roof before any work is booked.
