02 - How it works

Our process for Roof Energy Efficiency in Cork.

Every project follows a clear inspection, quote, delivery, and quality review path so you know what is happening before work begins.

Our Installation Process for Roof Energy Efficiency
Step 1

Our Installation Process

Every energy efficiency upgrade starts with thermal imaging to identify heat loss points in your roof structure. We use advanced diagnostic equipment to measure current insulation performance and airflow issues. Our installations combine mineral wool insulation with proper eaves ventilation, ensuring your roof stays thermally efficient without moisture problems or mould growth.

Step 2

Thermal Imaging Assessment

Our on-site assessment examines your attic’s current insulation depth, ventilation systems, and heat loss patterns using thermal imaging cameras. We measure existing insulation thickness against the 300mm standard, inspect all roof components for moisture damage, and photograph the attic space for documentation. Most Cork homes built before 2010 have inadequate insulation depth or ventilation blocking that reduces thermal performance. We identify these issues and calculate your potential heating cost savings based on your roof’s size and current condition. You’ll receive a detailed report showing exactly where heat escapes, recommended solutions with transparent pricing, and estimated SEAI grant eligibility. No hidden fees or pressure – just honest recommendations from Cork’s roofing specialists with 17 years of local experience.

Step 3

Professional Installation Service

Professional installation combines high-performance Knauf Earthwool or mineral wool insulation with proper ventilation cards at the eaves to prevent moisture buildup. We install insulation to 300mm depth using cross-layer techniques that eliminate cold spots and thermal bridging. Every installation includes pipe and tank lagging to prevent freezing, insulated attic hatches to stop drafts, and ventilation systems that protect your roof timbers from condensation damage. Most Cork homes are completed in one day with minimal disruption. Our work meets current Building Regulations and SEAI standards, ensuring grant approval and improved BER ratings. All installations include post-completion thermal checks and detailed documentation for your records.
