Roof Insulation Fareham
Roof Insulation Specialists in Fareham
At Loft Insulation Specialists, we help Fareham homeowners cut heating bills and stay warmer with professional roof insulation, fitted at rafter level to meet Part L building regulations. With over 40 years of experience across Hampshire, we know the area’s roofs — the pitched, accessible lofts of the 1960s and 70s expansion estates around Portchester and Hill Park, and the steeper roofs of the older High Street conservation core. Sitting at the head of Portsmouth Harbour, local roofs take the brunt of wind-driven heat loss off the Solent.
Heat rises, and up to 35% of your home’s warmth can be lost through the roof. We insulate between and over the rafters with 300mm Knauf Earthwool or slimline Superfoil to reach a 0.16 W/m²K U-value, keeping habitable lofts and room-in-roof spaces comfortable year-round and trimming around £200–£400 a year off bills.
We handle the full building control process for you, so there is nothing to arrange yourself. Every job starts with a free, no-obligation survey and a fixed-price quote — no high-pressure sales, no jargon, just straightforward advice.
How Fareham homeowners benefit from Roof Insulation
At Loft Insulation Specialists, we fit roof insulation, one of the most effective upgrades available, on a Fareham home. Heat rises, and without proper insulation at roof level much of the energy you pay for escapes straight through the structure — a real issue across the town’s 1960s and 70s expansion estates and the older, steeper-roofed terraces of the High Street conservation core. Whether you have a conventional trussed loft, a room-in-roof conversion, or a pitched roof you plan to make habitable, we insulate between and over the rafters with Knauf Earthwool or Superfoil multifoil to suit the build. Knauf Earthwool mineral wool is fitted at 300mm depth, exceeding the 270mm government minimum, while slimline Superfoil reaches comparable performance where headroom is tight — both targeting a 0.16 W/m²K U-value that meets Part L of the Building Regulations. On cold-roof constructions we include 25mm eaves ventilation as standard to keep air moving and prevent condensation. We do not install spray foam. After a proper look at your roof, we’ll recommend the right material and depth for your Fareham property.
Why Fareham Homes Need Roof Insulation
Heat escaping through an uninsulated or poorly insulated roof increases your energy bills and makes your home harder to heat evenly. In Fareham, where housing stock includes properties from many different eras, roof insulation levels vary considerably. Upgrading to current standards can make a noticeable difference to comfort and running costs, particularly during the colder months.
Knauf Earthwool Mineral Wool Insulation
Knauf Earthwool is installed to 300mm depth between and over rafters. It provides high-performance thermal insulation along with acoustic benefits and fire resistance. For Fareham properties with standard rafter depths, this is often the most practical and cost-effective option, priced between £900 to £1,200 depending on roof size.
Superfoil Reflective Multifoil Insulation
Superfoil achieves comparable thermal performance in a much thinner build-up than mineral wool. This is particularly useful in Fareham properties where rafter depth is restricted or where maintaining headroom matters. Superfoil also provides a radiant barrier that reflects heat. Typical installation costs range from £1,200 to £1,800.
Building Regulations and Certification
Roof insulation in Fareham must comply with Part L of the Building Regulations, which sets thermal performance standards for building elements. We target a U-value of 0.16 W/m²K and handle the building regulations notification on your behalf. This ensures the work is properly recorded and documented.
Warranties and Long-Term Performance
Our roof insulation installations carry warranties of 10 to 25 years depending on the product used. Both Knauf Earthwool and Superfoil are reliable, well-established products that maintain their performance over the long term when properly installed.
