Ashmark Roofing comes highly recommended across N21 and surrounding areas, with customers repeatedly praising Tony Hewett and the team (including Steve, Paul, Brad, and their assistants) for being quick to respond, clear in their explanations, and genuinely reliable.

What Customers Say

  • Quality workmanship and attention to detail: Work praised includes repointing zinc/flashings, fixing slipped tiles, stripping back difficult leak areas, and installing air bricks and new gutters—described as “neat,” “tidy,” and to a “very high standard.”
  • Clear communication and good value: Many highlight “clear throughout” communication, helpful advice, and solutions tailored to the problem—such as diagnosing damp on a gable end—while also noting they stick to the agreed price and present documentation/guarantees.

    "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."

    Ivor Davies - Image 1 "This is the second time I have used Ashmark Roofing as I was very satisfied with their work previously. Tony diagnosed the source of dampness on the gable end of my house as water running off a rendered section of wall from a poorly executed loft conversion by the previous owner. They installed a new gutter to route the water runoff and installed air bricks to vent two chimney stacks that had been capped off when the loft conversion had been done. They also repointed the wall where required. I'm pretty confident that our problem has been solved at a price that was fair."
