Next Generation Insulation Ltd was founded in Leicester by Dean Simpson, who brings over ten years of hands-on roofing experience. His background in property renovation and House in Multiple Occupation (HMO) conversions built a network of time-served tradesmen and a focus on proper residential energy efficiency. The roofing division covers traditional pitched roofing, natural slate installations, agricultural structures and historic timber frame restorations. The back-office team adds over twenty years of operations and finance experience, which keeps every project organised from first enquiry to final sign-off.
The Midlands holds a mix of property ages and styles, and each brings its own roofing demands. Victorian and Edwardian terraces across Leicester and Nottingham often carry natural slate with detailed valley and flashing work. Red-brick semis from the 1930s in Coventry and Derby tend to use clay tiles or concrete tiles. Rural and agricultural buildings around Stafford and Staffordshire call for larger profiled sheet and fibre cement systems. Our teams match regional materials, from Welsh slate to clay tiles, and weatherproof roofs against the wind-driven rain and winter frost common across the region.
The company holds a 5.0 rating from 28 Google reviews and has completed over 227 spray foam removal projects, including 66 combined removals and re-roofs. Across those jobs we hold a 100% lender acceptance record, with completed cases accepted by major lenders including Santander, Nationwide and Barclays.

A roof replacement is guided by condition, not age alone. We install complete roofing systems for houses, extensions, garages and commercial buildings, and we replace roofs once the covering, underlay, timbers, flashing or ventilation reach the end of their service. Each system includes new battens, breathable membrane or felt, tiles or slate, ridge and hip work, lead flashing, valleys and matched fascias, soffits and guttering. Every roof replacement carries a 10 year insurance-backed guarantee.
A leaking roof rarely needs a full replacement. We carry out roof repairs for broken and missing tiles, slipped or cracked slate, failed lead flashing, leaking valleys, cracked ridge and hip tiles, torn felt and damaged membranes. Water can travel along battens and rafters before it shows on a ceiling, so we trace where the water entered rather than patching the nearest tile. Storm damage, chimney junctions and roof windows are all covered.
A flat roof needs a covering matched to its deck and drainage. We install and repair EPDM rubber, GRP fibreglass, felt and single-ply systems on garages, extensions, dormers, balconies and porches. Cracks, blisters, lifted edges, failed seams and ponding water are common flat roof faults. We check the deck, outlets and junctions before we recommend flat roof repair or replacement.
Correct insulation lowers heat loss and supports a dry, healthy roof space. We fit loft and roof insulation for homes and commercial buildings, and we assess ventilation at the same time to reduce the risk of condensation and damp. Qualifying loft insulation can currently attract a 0% VAT rate on the materials until 31 March 2027 and all our insulation work comes with a 10-year guarantee.
Spray foam often stops a surveyor or valuer inspecting the roof structure, which can stall a sale or mortgage. We handle spray foam removal for open-cell and closed-cell foam using controlled mechanical and ice-blasting methods that protect the timber beneath. Our process is built around the evidence lenders ask for, and every removal comes with a certificate and a guarantee that the removal will pass with the mortgage company. We photograph the structure before, during and after the work where required.
The roofline carries rainwater away from the walls and roof edge. We clear, repair and replace guttering, downpipes, fascias and soffits when leaves, moss or age stop water draining correctly. Overflowing gutters can damage brickwork, render and roof edges over time. We check that rainwater reaches the downpipes and drains clear of the building.
Not sure whether you need a repair or a replacement? We inspect the covering, timbers, underlay, ventilation and insulation, then explain the findings in plain terms before any work begins.
Alongside our core work, we cover a wide range of specific roofing repairs and installations:

No, most roof leaks can be fixed without replacing the whole roof. A broken tile, failed flashing, leaking valley or a damaged section of membrane usually needs only a targeted repair. Replacement makes sense where the roof has widespread damage, failed underlay or rotten structural timbers.
The main warning signs are repeated leaks, widespread tile or slate damage, a sagging roofline, failed underlay and rotten roof timbers. Rising repair frequency, persistent loft damp, daylight showing through the roof and spray foam hiding the structure also point towards replacement.
A replacement roof cost depends on the roof size, shape, height, materials, access and structural condition. Scaffolding, waste removal, timber repairs, leadwork, insulation and any spray foam removal also affect the figure. We give a written price after inspecting the property.
No, many roofs can be repaired after the foam is removed. A new roof is only needed when the underlay, battens, timbers or covering have suffered wider damage. We assess the structure during removal and discuss the findings before any further work.
Yes, we repair roofing, membranes, battens, timbers and ventilation once the structure is exposed. Because our background is roofing, we carry out permanent external repairs rather than temporary internal patches. Any extra work is agreed with you first, with no hidden costs.
Yes, we fit suitable loft or roof insulation once the foam is removed and any repairs are complete. We check the loft ventilation at the same time to keep the roof space dry. Our loft insulation carries a 25 year insurance-backed guarantee.
Yes, we hold Public Liability Insurance and an Environment Agency Waste Carrier Licence, and we offer insurance-backed guarantees. Roof replacements carry a 10 year guarantee, loft insulation carries a 10 year guarantee, and every spray foam removal comes with a certificate and guarantee that it will be accepted by the mortgage company.
