Alliance Roofing & Building is a local, hands-on roofing company working across Streatham and the nearby areas. Roofs in Streatham take a beating, whether you are on Streatham High Road, near Streatham Common or tucked away on a side street off Streatham Hill. From small leaks to full new roofs, our Streatham roofers handle every aspect of your roof, gutters and uPVC so your property stays dry, safe and protected all year round. We work on everything from Victorian terraces and maisonettes to newer estates and commercial units across SW16, SW2, SW12 and CR4.
Our team combines roofing and building experience, so we understand how your roof, loft, walls and guttering all work together. We are fully insured, trained for work at height and used to working in tight London streets without upsetting the neighbours. Whether you need a simple repair, a new flat roof or a full re-roof, you deal with the same small team from first survey to final sign off. We turn up on time, inspect the roof properly, show you photos of what we find and send a clear written quote.
If your roof is reaching the end of its life or constant repairs are adding up, we supply and fit complete new roofing systems, removing the old materials, inspecting the structure underneath and installing modern, long-lasting coverings to current building regulations so your home is protected for years, not just the next winter. Storm damage and sudden leaks do not wait for office hours, so our emergency roofer service in Streatham can make your property safe and watertight, stopping water getting in, then return to complete a permanent repair once the weather allows.
We install new tiled, slate and flat roofs across Streatham, built to current standards so your home is protected for years, not just the next winter. When a roof is past saving, we remove the old materials, inspect the structure and timbers underneath and fit a modern covering suited to your property and budget. From Victorian terraces and maisonettes to newer estates and commercial units, we match the right system to the roof and leave you with a finish that lasts.
We repair and replace pitched roofs on terraces, semis and detached homes across Streatham, sorting slipped tiles, worn ridges and tired valleys before they turn into bigger problems. We renew battens and felt where needed and can re-roof full elevations when a patch repair will not last. If your loft is draughty, damp or losing heat, we can also advise on insulation and ventilation so the whole roof performs as it should.
Flat roofs need the right materials and a careful installation. We install and repair flat roofs on extensions, garages and porches across Streatham using felt, fibreglass and rubber systems that are laid to fall and built to cope with South London rain. Before we start, we check falls, outlets and upstands so water drains properly and does not sit on the surface causing future leaks.
From a single missing tile to recurring leaks around chimneys and valleys, our local roof repair team in Streatham finds the cause of the issue and repairs it properly rather than just patching the surface. We locate the source of the problem, whether it is cracked leadwork, damaged flashing, loose ridge tiles or worn pointing, and put a proper fix in place. We always talk you through the options, with photos, before any work starts.
If your roof fails without warning, we provide emergency roofer callouts in Streatham to make the roof safe, stop water getting in and plan a lasting repair with you. Storm damage and sudden leaks do not wait for office hours, so we carry out temporary make-safe works, such as tarping or securing loose sections, and then return to complete a permanent repair once the weather allows. You speak directly with a roofer, not a call centre.
We replace rotten timber fascias, soffits and bargeboards with modern uPVC systems that tidy up the roofline and reduce future maintenance, in a range of colours and styles to suit Streatham properties from period terraces to modern homes. Leaking or sagging gutters can cause damp patches and stained brickwork, so we also repair, realign and replace gutters and downpipes so rainwater runs off your roof and away from the walls instead of overflowing into brickwork and paths.
Chimneys are often the first part of the roof to show signs of age, so we repoint and rebuild chimneys, replace damaged leadwork and deal with loose pots and cracks that often sit behind long term leaks. Old spray foam insulation can cause problems when selling or remortgaging, so we safely strip it back from roofs and lofts, helping the structure dry and breathe as it should. We also clear moss and debris from tiles, clean the roof surface and unblock gutters, using methods suited to your tile type so small problems are spotted early.
