Consumer feedback

Generated from the text of this trader's consumer reviews

Ashmark Roofing comes highly recommended by long-term customers across Barnet and surrounding areas, with many praising how “quick, efficient, professional and good value” the team is. Tony (the proprietor) and Steve are repeatedly noted for clear communication, detailed explanations of the work, and turning urgent roofing issues around fast—such as emergency parapet repairs with scaffolding erected in a week and the job completed the next day.

What Customers Say

  • Reliable timing and responsiveness: Customers say Tony “quick to reply to my request for a quote,” with work scheduled and completed promptly, including one job where scaffolding and paperwork were arranged and work finished “in under four weeks.”
  • High-quality workmanship and attention to detail: Reviews highlight expert repairs and renewals—lead flashing and filleting, repointing flashings and abutments, bay tiling, moss clearing, gutter repairs, and flat roof replacements—often described as “to a very high standard.”
  • Clean, tidy sites and clear communication: Many mention the team left everything “clean and tidy,” kept residents informed, and shared photos—Steve “sent me photos of all the work he’d done”—with before/after evidence on request.

    Andrew - Image 1 "Quick, efficient, professional and good value work. Repair to parapet between adjoining rooves was treated as an emergency because three heavy cap tiles had already fallen. Job was estimated in a few days, scaffolding erected in a week and the job completed the next day by two experienced professionals."

    "Tony had carried out some repairs to the roof at the front of the house two weeks earlier and I asked him to quote for some repairs to the rear of the house. The job was completed to time and to a high standard. I am really pleased with his work, assisted by Steve. I would have no hesitation in recommending this firm to friends and neighbours."

    "Tony was quick to reply to my request for a quote, which came through as very competitively priced. The job was completed very efficiently and a to a very high standard. I am really pleased with the work done to replace the lead flashing and filleting and have asked Tony to do the same for the back of the house."
