Roof Insulation Farnborough
Professional Roof Insulation in Farnborough
At Loft Insulation Specialists, we help Farnborough 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 town’s roofs — from the pitched, chimney-stacked Victorian terraces of North Camp and South Farnborough to the post-war semis of Cove and Southwood, where heat escapes fast through an uninsulated roofline.
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 Farnborough homeowners benefit from Roof Insulation
At Loft Insulation Specialists, we fit roof insulation, one of the most effective upgrades available, on a Farnborough home. Heat rises, and without proper insulation at roof level much of the energy you pay for escapes straight through the structure — whether that is a chimney-stacked Victorian terrace in North Camp or a post-war semi in Cove or Southwood, many were built to the thermal standards of their day and now fall short. Whether you have a pitched roof, a converted loft, or a room in the roof, we insulate between and over the rafters with Knauf Earthwool or Superfoil multifoil to suit the build, targeting a 0.16 W/m²K U-value that meets Part L of the Building Regulations. We will recommend the right material and depth after a proper look at your roof.
Why Farnborough Homes Need Upgraded Roof Insulation
Many properties across Farnborough, Cherrywood, Cove, Farnborough Green, Farnborough Park, North Camp, and Southwood were built when roof insulation standards were minimal or non-existent. Even homes that do have some loft insulation often fall short of the current 270mm UK minimum requirement. Inadequate roof insulation means higher heating bills, uneven room temperatures, and a lower EPC rating. Upgrading to properly installed 300mm insulation addresses all of these issues and can deliver annual savings of £200 to £400 on your energy bills. Whether you live in a semi-detached home in Cove or a detached property in Farnborough Park, professional roof insulation is one of the smartest investments you can make.
Knauf Earthwool Mineral Wool Insulation
Knauf Earthwool is a trusted mineral wool insulation that we install to a full 300mm depth, exceeding the 270mm UK building regulations minimum. It is laid between and over the ceiling joists in your loft space, creating a continuous thermal barrier that dramatically reduces heat loss through the roof. Knauf Earthwool is non-combustible, does not absorb moisture, and maintains its performance for decades. It is the ideal choice for most Farnborough properties with standard loft access and joist depth. Typical installation costs for Knauf Earthwool range from £900 to £1,200, and every installation is backed by manufacturer warranties of 10 to 25 years alongside our own workmanship guarantee.
Superfoil Reflective Multifoil Insulation
Superfoil is a high-performance reflective multifoil insulation that is particularly well suited to properties around Farnborough where rafter depth is limited. Unlike bulky mineral wool, Superfoil achieves excellent thermal performance in a thin profile by reflecting radiant heat back into the living space. This makes it an excellent solution for older properties in North Camp and Farnborough Green where maintaining roof headroom is important. Superfoil installations typically cost between £1,200 and £1,800, and come with manufacturer warranties of 10 to 25 years. We do not install spray foam insulation — we specialise in its removal — so you can be confident that we will recommend only proven, regulation-compliant products for your home.
Building Regulations and Certification
All roof insulation work in the UK must comply with Part L of the Building Regulations, which sets minimum standards for energy efficiency. We handle the entire building regulations process on your behalf, from initial notification through to final certification. This means you do not need to arrange your own building control inspections or worry about compliance paperwork. Our three-stage process covers survey and planning, installation and inspection, and final certification, ensuring everything is completed correctly and documented. For cold roof installations, we ensure 25mm eaves ventilation is maintained to prevent condensation problems. At the end of every job, you receive full certification confirming your installation meets current standards.
Warranties and Long-Term Protection
Every roof insulation installation we carry out in the Farnborough area is protected by comprehensive warranty cover. You receive both a workmanship warranty from us, covering the quality of the installation itself for 10 to 25 years, and a separate manufacturer warranty from either Knauf or Superfoil covering the product for 10 to 25 years. This dual layer of protection gives you complete peace of mind that your investment is safeguarded for the long term. We also provide full cleanup after every installation, leaving your loft space tidy and your home exactly as we found it.
