Sound Familiar?
If any of the below ring true, your roof insulation could be the culprit:
- Upstairs rooms are noticeably colder than the rest of the house
- Your heating bills are high despite other improvements
- Your home loses heat quickly once the heating goes off
- You have a flat roof that’s never been properly insulated
- Your existing roof insulation is old, damaged or insufficient
We survey every property before recommending anything — and if roof insulation isn’t the right fix, we’ll tell you.
What We Offer
Pitched roof insulation
Pitched roof insulation
The most common roof type in the UK. We insulate between and over the rafters using mineral wool or PIR board systems — keeping heat in and bringing your roof up to the current recommended U-value of 0.18 W/m²K.
Flat roof insulation
Flat roof insulation
Flat roofs lose heat quickly and are often overlooked. We install warm deck systems using PIR or EPS boards above the roof deck — thermally efficient, moisture-resistant and built to last.
Roof insulation top-ups
Roof insulation top-ups
If your existing insulation is undersized, deteriorating or simply not doing its job, we can assess what’s there and top up or replace it to the correct specification.

FAQs
Loft insulation sits at floor level in an accessible loft — the most common and cost-effective option. Roof insulation sits between or above the rafters, closer to the roof covering itself. It’s the right choice for rooms in the roof, converted lofts or flat roofs where floor-level insulation isn’t possible.
If your home is hard to heat, upstairs rooms are cold, or your insulation is more than 25 years old, it’s worth getting it checked. Our free survey will tell you exactly where you stand.
Most roof insulation projects are completed in a day or two, depending on roof type and property size. We’ll give you a clear timeframe before we start.
