Services
Pitched Roofing
At Alliance Roofing & Building, we undertake pitched roofing projects for homes, businesses and heritage buildings. Our services encompass roof construction, refurbishment, re-roofing and repairs using quality slate and tile materials. We carry out specialist leadwork and flashing around chimneys, valleys and abutments. With over 40 years of experience, we focus on lasting weather protection.
Flat Roofing
We specialise in creating dependable flat roofs for garages, dormers, extensions and larger commercial buildings. Our experienced team installs EPDM membranes, hard-wearing GRP fibreglass and cost-effective multilayer felt systems. Alongside new installations, we undertake repairs, maintenance and re-roofing projects. Every roof is designed to provide effective waterproofing, withstand weather exposure and offer lasting protection.
Roof Repairs
We provide reliable roof repairs for residential and commercial properties, addressing leaks, damaged tiles, faulty flashing and storm damage. Our experienced team works on pitched, flat and older roofing structures. Every repair begins with a thorough inspection to identify the underlying problem. With over 40 years of combined experience, we deliver lasting workmanship without call-out charges.
New Roofs & Re-Roofing
Our new roofing and re-roofing services provide long-lasting protection for properties with ageing or damaged roofs. We work with various materials, including natural slate, fibre-cement slate, clay tiles and concrete tiles. Before recommending replacement, we inspect the roof and explain the available options. Our work carries a 10-year workmanship guarantee, supported by £1 million public liability insurance.
UPVC Installation
We specialise in installing low-maintenance uPVC components that strengthen and enhance your property's roofline. From replacing worn guttering to fitting protective bargeboards and weatherproof cladding, our work addresses essential roofing requirements. Our durable materials help prevent leaks, damp and timber deterioration while maintaining an attractive finish. Each installation combines careful workmanship, lasting performance and a choice of finishes.
Spray Foam Removal
We specialise in safely extracting spray foam insulation to restore roof integrity and address potential mortgage, survey and insurance concerns. Our services cover open-cell and closed-cell materials installed in lofts and roof structures. After removal, we conduct a thorough inspection and offer guidance on any underlying defects. Where necessary, we can replace underlay, install insulation or undertake re-roofing.

I’ve had alliance redo most of my roof and chimney over three separate jobs and they’ve done a nice job overall. Workmanship is good, no issues at all with that. They came back to fix a couple of snags. Mitchell is very helpful with making appropriate suggestions about what is worth doing and what isn’t. My only negative has been with some communication being missed or taking a long time to resolve (e.g. paperwork for building controls).
