0191 468 3081Loft Insulation North East
Loft insulation can help reduce heat loss. Material options depend on the roof, existing insulation and intended loft use. Contact us to discuss suitable options for your property.
Insulation may be laid between and over ceiling joists where suitable. Existing insulation, ventilation and available space should be assessed before choosing a material and thickness.
We can discuss new loft insulation or a top-up of existing material. Ventilation, access and moisture-control details should be considered alongside the proposed insulation work.
Roof Insulation Boards
For loft conversions, habitable roof spaces, and maximum thermal performance, rigid PIR insulation boards are the premium choice. INFINITE Roofing installs high-performance boards from industry leaders Kingspan and Celotex, delivering exceptional R-values per millimetre of thickness. These boards offer significantly higher insulating performance than mineral wool, making them ideal where space is at a premium — particularly in loft conversions where every centimetre of headroom matters.
We install rigid insulation boards in two primary configurations: between the rafters and over the rafters. Between-rafter installation involves precision-cutting boards to fit snugly between the timber rafters, with all gaps sealed using expanding foam to eliminate thermal bridging. Over-rafter installation, carried out during a roof replacement, places a continuous layer of insulation above the rafters before the battens and tiles are fitted. This method eliminates cold bridges entirely and provides the highest possible thermal performance for North East homes.
Rigid boards may suit a loft intended for living space. The design needs to consider the roof structure, headroom, ventilation and moisture control rather than insulation alone.
Warm Roof vs Cold Roof Insulation
Understanding the difference between warm roof and cold roof insulation is essential when planning your insulation project. A cold roof places the insulation at ceiling level, between and over the joists, keeping the loft space cold and ventilated above. This is the traditional and most affordable method, ideal for properties where the loft is used only for storage. The roof space above the insulation must be ventilated at the eaves to prevent condensation forming on cold timber surfaces and roofing felt.
A warm roof places the insulation at rafter level — either between, below, or over the rafters — keeping the entire roof space within the thermal envelope of the building. This method is essential for loft conversions and habitable roof spaces, as it keeps the room beneath the roof slope warm and comfortable. Warm roof constructions require a vapour barrier on the warm side of the insulation to prevent moisture from the living space reaching the cold outer roof structure and causing condensation.
We can assess your roof and discuss how the loft is used. The insulation layout, ventilation and vapour-control details depend on the design and proposed work.
Roof Ventilation North East
Proper roof ventilation is critical to the long-term health of your roof and the effectiveness of your insulation. Without adequate ventilation, warm moist air from the living spaces below rises into the roof void and condenses on cold surfaces — leading to damp timber, mould growth, and premature deterioration of roofing materials. The North East's cold, wet climate makes this issue particularly prevalent, as the temperature differential between inside and outside creates ideal conditions for condensation.
We offer roof ventilation options including soffit, ridge and tile vents. The appropriate arrangement depends on the roof construction and existing ventilation. Over-fascia ventilation may also be an option where suitable.
Existing ventilation should be considered before adding insulation. Proposed vent upgrades can be discussed and included in the agreed scope of work.

Roof Insulation FAQs
How much does roof insulation cost in the North East?
Insulation costs depend on the roof area, existing material, ventilation and access. Contact 0191 468 3081 for availability and a free, property-specific quote.
What type of roof insulation is best?
Suitable insulation depends on the roof construction, available space and loft use. Mineral wool and rigid boards suit different applications. We can discuss options after assessing your property.
How thick should loft insulation be?
Thickness depends on the material, roof construction and proposed work. Existing insulation, ventilation and moisture control should be considered together rather than applying one depth to every property.
Can you insulate during a roof replacement?
Insulation upgrades can be considered during roof replacement. We can discuss suitable options and include agreed insulation work in your property-specific quote.
Does roof insulation really save money on heating?
Insulation can reduce heat loss, but heating bill changes depend on the property, existing insulation, heating use and energy tariffs. We do not promise a particular saving or payback period.
What is roof ventilation and why is it important?
Ventilation allows air to circulate and helps manage moisture in the roof space. Tile, ridge and soffit vents suit different roof designs. Ventilation should be assessed alongside insulation.
Do you install insulation between rafters?
We offer rigid board installation where suitable for the roof construction. The layout, ventilation and moisture-control details depend on the property and intended use of the space.
