Why Roof Insulation Matters
A poorly insulated roof can be one of the biggest sources of heat loss in a home.
At Retrofit Design Ltd, we’ve installed roof insulation nationwide, helping homeowners keep warm in winter, cool in summer and spend less on energy. Whether you have a pitched or flat roof, we can retrofit effective, long-lasting insulation that improves your BER rating and comfort levels.
What Is Roof Insulation?
Roof insulation adds a high-performance thermal layer to your home’s roof structure, preventing warm air from escaping and reducing heat transfer.
We offer solutions for both pitched and flat roofs:
- Pitched Roof Insulation – installed between and over rafters to create a thermal barrier while maintaining ventilation and roof integrity.
- Flat Roof Insulation – can be fitted as a warm roof (insulation above the deck) or cold roof (insulation below the deck). Proper installation also helps prevent condensation, damp and mould, protecting the roof’s structure and extending its lifespan.
