Balconies and terraces are high-risk areas where poor detailing often leads to leaks into rooms below. At JB Roofing Specialists Ltd, we install seamless liquid-applied waterproofing systems designed to withstand foot traffic, standing water, and long-term exposure.
We operate across Herefordshire and Gloucestershire, delivering durable balcony and terrace solutions for both residential and commercial properties.

Warm deck vs cold deck
Warm Deck Flat Roof
- Insulation installed above the structural deck
- Reduces condensation risk
- Improves thermal performance
- Compliant with current building regulations
- Ideal for new builds, extensions, and commercial refurbishments
Cold Deck Flat Roof
- Insulation installed between rafters
- Requires correct ventilation strategy
- Suitable where height restrictions prevent warm deck build-up
We will always advise the correct construction method based on your roof design, usage, and compliance requirements.
Roofing lanterns are a popular addition to flat roofs, allowing natural light to flood the space below while creating a modern architectural feature. When installed correctly, they enhance both the appearance and usability of kitchens, extensions, and open-plan living areas.
At JB Roofing Specialists Ltd, we install roofing lanterns as part of new flat roof systems or refurbishment works, ensuring correct upstands, falls, and full integration with EPDM or liquid-applied waterproofing systems for long-term performance.
Benefits include:
- Increased natural daylight
- Improved sense of space and height
- Enhanced property value and visual appeal
- Optional ventilation for improved airflow
Installed professionally, a roofing lantern is both a practical and visually striking upgrade to any flat roof.
