Experienced With Slough Homes
Slough grew quickly in the 1930s and again after the war, so many roofs here are interwar tiled roofs or post-war estate roofs, with some older terraces near the centre.
Roof Repairs Slough: What's Included
From a single slipped tile to a full re-roof, our professional roofing team covers every job across SL1.
Trusted Roof Repairs
Slipped tiles, cracked ridge pointing, failing lead valleys and broken ridge caps. Most repairs in Slough are completed within 24 to 48 hours of your call.
Emergency Roof Repair
Storm damage, sudden leaks, a fallen chimney stack — we make the roof safe and weatherproof quickly, then return to finish the full repair.
Flat Roof Repair & Replacement
Many Slough homes have flat-roofed rear extensions, garages and dormers. 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
Full strip-and-reroof to NFRC industry standards, in clay, concrete, natural slate or synthetic slate. Every new roof includes a written specification and a signed 10-year guarantee.
Chimney Repairs
Many of Slough'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
UPVC, aluminium and cast iron gutter replacement, downpipe re-routing and fascia renewal. Most guttering jobs across SL1 are finished in a single day.
Soffit & Fascia Renewal
Fascia and soffit board replacement on older Slough 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 Slough Property Type
Slough's homes range from older terraces around the town centre and Upton to 1930s semis and post-war estates such as Britwell, so we approach each roof differently.
Slough Housing Stock
Slough expanded quickly in the 1930s as the trading estate brought work to the town, and again after the war with new estates such as Britwell. As a result, much of the housing has interwar hipped tile roofs or post-war concrete-tiled and low-pitched roofs, with some older slate-roofed terraces near the town centre and Upton. Typical faults are slipped tiles, worn ridge and verge mortar, and leaking flat-roofed extensions. Upton and Colnbrook include conservation areas, so we check with Slough Borough Council before changing roof materials there.
Fast Local Response
Based 20 to 25 minutes from Slough, 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 Slough call-outs are slipped or missing tiles after high winds, leaks on flat-roofed extensions and garages, and gutters blocked by leaves. Slough is the furthest town we cover from our Southall base, so we always confirm an arrival time when you call.
