What flat roof work do we do in Holyhead?
Torch-on felt roofing
Where a flat roof in Holyhead already has a felt covering and the building owner wants like-for-like, torch-on is the natural replacement. The old roof is stripped, the deck checked and the new layers laid, often with warm-roof insulation added when the space below is heated.
Extension and kitchen roofs
Condensation drives some replacements in Holyhead. Older extension roofs were often built cold, with insulation between the joists and no reliable vapour control. Warm air from the kitchen reaches the cold deck, moisture builds up and the timber suffers. A warm roof deals with the cause, not just the stain.
Commercial flat roofing
Owners and agents in Holyhead can plan spending with a phased programme: urgent repairs now, then re-roofing section by section over one or more budget years. Each phase is priced separately in writing, and the survey and quote for replacement work are free, with no obligation to go ahead.

What flat roofs are typical in and around Holyhead?
In a town like Holyhead flat roofs are mostly on shops with flat-roofed rear stores below flats and low-rise post-war blocks of flats. The climate is part of the brief. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Holyhead?
Where approval is needed it goes to Isle of Anglesey County Council building control, or a registered building control approver.
