THE KNOWLEDGE LIBRARY
Practical answers for better roofing decisions.
This library brings together the systems I work with, the details I inspect and the lessons that repeatedly matter on site. It is written for designers, contractors and building owners who want a clearer view before work begins.
Liquid Waterproofing
Winkler, Res-Tec and Scott Bader roof, balcony and below-ground systems, reinforced GRP, repairs and specialist coatings—selected around substrate, moisture, pressure and detailing.
OPEN SECTION →02Flat Roofing
DANOSA, Ravago and MIDA working ranges, an independent EPDM systems library, and historical Börner and TECHNONICOL archives—organised by build-up, attachment and detailing.
OPEN SECTION →03Pitched Roofing
Eurovent control layers, current MIDA shingles and historical SHINGLAS experience—connecting the covering, underlay, airtightness and critical interfaces.
OPEN SECTION →04Roof Refurbishment
Survey-led strategies that address the cause of failure—not simply the visible leak.
OPEN SECTION →05Inspections & Surveys
Evidence-based condition assessment, defect diagnosis and practical reporting.
OPEN SECTION →06Specification Support
System selection, build-up review and detail coordination from design to installation.
OPEN SECTION →07Building Performance
Project-specific DANOSA acoustic systems for impact, airborne and low-frequency noise across floors, walls, ceilings and building services.

- Perspective
- Product · Specification · Site
I am a roofing and waterproofing technical specialist based in Ireland. My wider construction background extends back to 2007, with my work focused specifically on roofing, waterproofing and building-envelope systems since 2019.
In my current role as Technical Sales Manager — Roofing & Waterproofing, I work between manufacturers, architects, quantity surveyors, contractors, builders merchants and installation teams across Ireland and Northern Ireland.
My experience covers liquid-applied waterproofing, torch-applied and self-adhesive membranes, PVC, EPDM, GRP, insulation, airtightness, breathable pitched-roof underlays and roof ventilation systems.
HOW I APPROACH A ROOF
Knowing the product name is the easy part. The real work is understanding the substrate, moisture, compatibility, detailing, workmanship and conditions in which the system will be installed.

TECHNICAL CONVERSATION
Have a roof question worth looking at properly?
For specification support, system selection, inspection discussions or professional collaboration. Share the key details and I will respond using your preferred contact method.
An initial enquiry does not constitute a project specification or design instruction. Project-specific guidance requires review of the relevant information and site conditions.
