Customers repeatedly highlight how Tony and Steve explain what they’ll do (and why), keep to quoted prices, and leave sites “clean and tidy” with before-and-after photos, whether it’s repointing chimney stacks, repairing lead flashings and zinc work, or replacing broken tiles and tackling tricky damp sources.

What Customers Say

  • Trusted, detailed workmanship: Clients describe Ashmark as “completely trustworthy” and note Steve’s careful approach—everything from chimney pot replacements and air-bricks to stripping back problem areas to locate leaks, with photos and clear explanations.
  • Professional communication & reliability: Reviews frequently mention fast responses and smooth coordination, with Tony arranging scaffolding and paperwork (including Haringey Building Control visits where required) and updating customers throughout.
  • Punctual, tidy, good value: Work is repeatedly described as punctual, efficient and “no nasty extra costs,” with teams such as Paul and Brad praised for being “super professional” and for leaving properties neat after jobs like flat roof renewals, gutter repairs, fascias/soffits and slate bay tiling.

    "We engaged Ashmark to re-cover two flat roofs and also to install an insulated roof on a garden workshop. The whole experience was great, from arranging the initial visit, receiving the quote, organising the scaffolders and carrying out the work. Despite the heatwave, all the work was carried out on schedule. Steve and John were very polite and friendly and they take great pride in the quality of their work, which clearly shows. We're really pleased with the final result and would highly recommend Ashmark Roofing."

    "I have used Ashmark Roofing on a few occasions in the past following a recommendation from a friend. On each occasion, including the latest one, I have felt that whole process (from giving the estimate to completing the work) has been performed professionally and to a high standard. In each case they have explained what they were going to do and why and then left the site clean and tidy. I would have no hesitation in using them again in the future or of recommending them to others."

    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."

    "I have used Ashmark Roofing for roof maintenance over 5+ years. Make sure you use the contact details on this website to prevent contacting the “clone” company. Steve discussed work that I thought needed to be carried out: replacing chimney pots with covers &detailed roof inspection. I received a detailed estimated for the work. It related to the following: -Arrange for the erection of scaffolding to side & rear elevations for access to 2 chimney stacks. -Remove 3 chimney pots & cap remaining. -Supply & bed 3 terracotta half round hoods into the flues. -Make good defects in flaunchings as required. -Rake out & repoint areas of defective pointing. -Check the condition of flashings & report to customer. Repair/replace one broken tile at the top of the side elevation roof slope. Work was carried out by Steve over 2 days. He showed me before & after photographs. I was happy with the friendly and courteous manner of both Steve & Tony (the business owner) & the way they communicated."
