Alliance Roofing & Building is a local, hands-on roofing company working across Wembley and the surrounding parts of north west London. From small leaks to full roof replacements, our Wembley roofers look after every part of your roof, guttering and roofline so your home stays dry and protected all year round. We replace and repair tiled, slate and metal roofs on properties across HA0, HA9, HA3 and NW10.
Our team combines roofing skill with general building knowledge, so we understand how your roof, walls and drainage all link together. Whether you need a simple repair, a flat roof replacement or a complete new roof, you deal with the same small team from first visit to final sign off. We work cleanly, keep you updated and treat every property as if it were our own.
If your roof is worn out or you are spending money on repairs every year, we supply and fit complete new roofing systems, removing the old coverings, checking the structure beneath and fitting new materials that suit your property and budget. Storm damage and sudden leaks do not wait for office hours, so our emergency roofer service in Wembley can make your property safe and watertight with temporary coverings or securing loose sections, then return to complete a permanent repair once the weather allows.
A small leak rarely fixes itself. Our roof repair team in Wembley deals with missing tiles, split flashings, loose ridges, broken gutters and more. We inspect the roof, take photos to show you the problem and explain your repair options in plain language. The aim is always a lasting fix that suits the age and condition of your roof, not a quick patch that fails at the next round of bad weather.
Our roofers work on all types of pitched roofs in Wembley, including clay and concrete tiles, natural slate and metal sheet systems. We put right slipped tiles, cracked ridges, damaged valleys and worn felt at the eaves. If there are signs of damp in the loft or daylight through the roof, we trace the source properly rather than just patching what you can see from the ground.
Flat roofs on extensions, garages and porches need careful detailing to stay watertight. We repair and replace flat roofs throughout Wembley using modern felt and liquid systems that are designed to shed water and resist pooling. Where the existing deck is sound we may be able to overlay it, giving a fresh surface without the cost of a full strip.
Alongside tiled and slate roofs, we can repair and replace certain metal roofing systems in Wembley, such as sheeted roofs on extensions, garages and small commercial buildings. We inspect the existing metal roof, advise on whether repair or replacement is the better option and quote accordingly, so you get the right solution for the structure rather than a one-size-fits-all answer.
Storms and heavy rain can cause sudden damage to roofs in Wembley, from lifted tiles to ripped flat roof coverings. We provide an emergency roofing service to make your property safe as quickly as we can. That may mean temporary coverings, securing loose areas or isolating damaged sections, followed by a clear quote for permanent repairs once things have settled. You speak directly with a roofer, not a call centre.
Tired timber boards at the roof edge can rot, peel and spoil the look of your home. We replace old fascias, soffits and bargeboards with low-maintenance uPVC on properties across Wembley, inspecting rafter ends, felt and fixings while the boards are off. Poor drainage can lead to damp patches and stained brickwork, so we also repair, replace and clean guttering and downpipes, checking falls, joints and brackets so water runs where it should.
Chimneys take the worst of the weather and are often the first part of a roof to fail, so we repair pointing, flaunching and lead flashings on stacks throughout Wembley and can fit cowls or remove redundant stacks. Spray foam insulation causes problems for many Wembley homeowners when they come to sell or remortgage, so we carefully strip it from rafters and install a breathable solution. We also offer gentle roof cleaning and moss removal, matching the method to your tile type so small problems are spotted early.
