Company info

Hi, my name is Garry and together with my two sons Alex and Calvin (hence ALCO roofing) we run a family business. On a personal note I have been working in the roofing industry for 28 years and in that time I have worked on all manner of projects from small repairs to re-roofing housing estates. We are polite, honest and above all take real pride in our work.

We are based in Bolton covering all areas within 50 miles of BL3. We are VAT registered.

We undertake all roofing work from tiling and slating to general roofing maintenance and repairs, with no job being considered as too big or too small. We guarantee a high standard of workmanship every time, with outstanding customer care. We adopt an honest approach to roofing where we go up onto your roof and take photos/video of any problems then come down and show you then together we can work out the best way to resolve any issues.

We compile roof reports where we go and take photos of any problems or potential problems, then make a report with attached photos highlighting issues then send to you via email

We also offer free, non obligatory quotes and estimates. We are fully insured and all operatives holding valid skilled construction skills Certificate cards, and CITB Level 2 NVQ diplomas in slating and roof tiling.
We are also members of the government backed COMPETENT ROOFER scheme that allows professional roofing contractors to self certify that there work meets building regulation standards so we can offer independent 10 year insurance backed guarantees on all roof refurbishments for your piece of mind.
We are registered installers of FIRESTONE rubber roof systems and PRO GRP glass fibre roof systems 

We are CHAS Accredited Healthy and Safety. The Director Garry O'Neill has obtained a NVQ Level 3 Diploma in Construction and Roofing. 

Please contact us today to discuss your requirements for free professional, friendly advice. We look forward to hearing from you.
