Our company employs only local, North and Mid Wales specialist tradesmen for slate roofing, tiling, lead work, solar and lightning protection. We are able to take on works of any size to the most complex designs and specifications. Established in 1971, by the late Anthony Gallagher Sr, with only a small team of employees.

In 1976 Anthony Gallagher Jr followed in his fathers footsteps, intervened and assisted with the growth and development of the company. By 1981 the firm within 10 years had successfully expanded and to this day is a growing business. A. Gallagher & Son Roofing has enjoyed more than half a century service in North and Mid Wales.

Our company is well respected across the North and Mid Wales and has built up a very good reputation over time, one which members of staff are all very proud of. The company has remained a family business since day one of production and we pride ourselves on providing the best possible service every time no matter how big or small the task in hand.
Services
We offer a whole range of services from general roofing, guttering and repairs to sales of products, lightning protection and roof based renewable energy such as Solar PV and Solar Thermal Hot Water. We combine all our services to bring you low cost roofing packages which are best value for money every time in whatever works you need carrying out.
We also specialise in flat roof instalment and repairs, we're based in Bangor, and carry out works ranging from Gwynedd to Anglesey county's and throughout all of the North Wales region. Using alternate methods of materials to ensure the job is completed to yours and our standards, to the greatest quality in the most efficient and effective way as possible.
Based in Bangor, we specialise in new roofing with everything from the finest slates in production straight from quarries based here in Gwynedd, to the more competitively priced slates and tiles from Spain and Canada. The main areas we cover are Anglesey, Gwynedd and Conwy so contact us today for a free quote or quick estimates based on roof area.
We employ specialist roofers in Gwynedd, Conwy and Anglesey. If your slate or tiled roof is leaking and in urgent need of attention or you just need general roof repairs throughout your existing roof, we can offer a quick response to any repair works which may need carrying out. No job is too big or too small so call for a free quote/estimate.
We can even supply Solar PV Electricity Panels and Solar Thermal hot water if required with your re-roofing package and we are most competitive in Anglesey, Gwynedd and Conwy. Deterioration of a roof could well mean that the covering (slate or tiles), has come to the end of its lifespan. Repairing in some cases can sometimes costs you more in the long run.

Critical: Professionalism, Responsiveness
Spoke to Tony first then his son Darren. I asked for a quote for a new roof Darren said he would come and see me over the weekend. It was a 'No show'. No explanation or request for a new appointment. Really fed up of contractors that say they turn up and then don't.

Can't recommend Gallagher Roofing enough. Real experts at what they do - an old family business, big enough to have the availability, all the matching reclaimed slate, and a meaningful warranty. but small enough that nothing is too much trouble. We had an entire roof repaired/replaced with them, including chimney repairs. They also installed a couple of Velux windows and sorted out some internal work e.g. plastering the areas inside. Everything was great. Darren not only gave the best value quote, he was also just a lovely guy to deal with - flexible and friendly. Gallagher Roofing gave a long
