Approved Specialist GRP Fibreglass Roofing in Ireland
PQ Fibreglassing employees are fully approved and trained contractors for Dryseal® and CrysticROOF® GRP fibreglass systems. Continual professional development and best practice for construction legislation and care of the environment is a key element of our working ethic. Technical and design support on projects is readily available to cost-in value engineering techniques and pass savings on to our customers.
One of the main reasons why we chose Dryseal as our main specialist GRP fibreglass system is the dedicated level of site based roofing expertise on offer for each and every project - regardless of size. Ease of communication, ethical values, exceptionally low embodied carbon footprint, the comprehensive insurance backed guarantee and of course, the stunning looks of the finished product. All add together to make every project a winner.
Living and working in Ireland is as important to us as it is to you. We don´t just travel across the Water for the odd job. We live and breathe Ireland. We understand the legislation. We understand and are involved in the culture. We employ Irish people who we know and trust. We love being in Ireland. And we´d love to do a great roofing job for you.

PQ Fibreglassing is one of the leading GRP (Glass Reinforced Polyester) fibreglass installers in Ireland, offering a comprehensive and competitive range of fibreglassing services nationwide. We travel anywhere in Ireland and endeavour to accommodate all working schedules.

Our main business and specialism is 'flat' roofing, using the Hambleside Danelaw Dryseal® and CrysticROOF® systems. Fibreglass can however be used in lots of applications - its beauty being that it can be moulded to any shape, offering endless possibilities for repair, build or fabrication applications. The list below shows applications in which we´re fully experienced:

  • Flat roofs
  • Roof valleys
  • Non-slip balconies
  • Secret gutters
  • Wet / shower rooms

  • Water tanks
  • Fascias
  • Dormer windows
  • Pond liners
  • Signage


PQ Fibreglassing can assist in a project at various stages to provide budget costs, advice and drawings for detailed elements of the roof:


Dryseal drawings in .dwg and .pdf format and BIM objects are available.


Insulated options are available for Dryseal roofs, without the need for an extra layer of OSB board over the insulation.


With the addition of decorative roll or rib trims, the look of lead or zinc can be achieved at reduced cost.


A certificate of compliance must now be signed off in order to comply with revised Irish building regulations. We´re fully conversant with the Regulations and able to ensure compliance.
