TrustMark Registered Local Roofing Specialists
Is a leaking roof, cracked ridge tile, or storm damage compromising your property? At Next Generation Insulation, we provide targeted, high-performance roof repairs that secure your home against the elements. Operating across Leicester, Nottingham, Derby, Birmingham, and the wider Midlands, our work is carried out by fully vetted, in-house technical teams.
We blend traditional roofing craftsmanship with advanced insulation and moisture-management expertise. Every project begins with a comprehensive, no-obligation structural survey to identify the root cause of your issue.
Minor roof issues can quickly escalate into extensive structural damage. Water tracking through a single displaced tile can compromise underlay felt, rot structural timbers, and degrade your home’s insulation. We offer rapid, durable repair solutions tailored to the unique architectural styles of the Midlands.
We source high-quality materials to match the existing aesthetic and structural requirements of your property:
Most common on modern Midlands estates. We frequently repair and replace models like the Marley Ludlow Plus, Redland 49, and Russell Grampian. Because water can track along interlocking channels, our team uses advanced leak detection to find the exact source of a fault rather than just patching visible damage
Prevalent on Victorian and Edwardian homes throughout Leicester, Nottingham, and Derby. These require expert double-lap fitting. We meticulously match the colour, size, and camber of replacement tiles to preserve weather protection and historical appearance.
These distinctive, textured plain clay tiles are common on 1920s and 1930s properties. We source genuine matching replacements to maintain the integrity of your roofline.
Common on period and terraced properties. For isolated damage, we use discrete lead or copper tingles to secure new slates. For widespread degradation, we strip, check, and relay the affected section using corrosion-resistant copper or stainless steel nails.
Repointing and Re-bedding: We remove failing mortar, clean the existing ridge tiles, and reset them using a flexible, frost-resistant mortar mix.
Mechanical Fixings (BS 5534): To meet modern building compliance, we introduce stainless steel clips to secure ridge tiles directly to the roof structure. This ensures your roof remains stable during high winds and no longer relies solely on mortar.
Dry Ridge Systems: We can upgrade your roof to a modern dry ridge system. By utilising high-grade plastic unions and mechanical fixings, this system eliminates mortar entirely, removing the need for future repointing work.
Real experiences from real people – featuring our expert team
Flat roofs on extensions, garages, porches, and dormer windows require specialised materials to prevent standing water from penetrating the decking:
| Material Type | Common Issues Addressed | Repair Approach |
| Traditional Felt | Blistering, splitting, cracking due to UV degradation. | Localised patching or strategic section replacement for roofs under 10 years old. |
| EPDM Rubber | Punctures, joint separation, perimeter lifting. | High-durability single-ply membrane splicing and chemical bonding. |
| GRP Fibreglass | Surface cracking, pinholes, structural movement noise. | Seamless resin re-coating and structural reinforcement layers. |
What sets our technical team apart is our comprehensive understanding of the roof as a complete thermal and ventilation system. We do not just fix the external leak: we protect the internal structural envelope.
When performing structural repairs, we adhere strictly to the BS 5250:2021 code of practice for management of moisture in buildings. If a repair requires replacing sections of underlay, we install high-performance breathable membranes paired with correct eaves and ridge ventilation.
This professional approach prevents interstitial condensation (often referred to as “loft rain”), a common side effect in modernised homes where increased insulation traps moisture vapour.
If your roof has been flagged during a homebuyers survey due to compromised timbers, long-term neglect, or poorly applied spray foam insulation, we can help. Our structural recovery process rectifies timber decay and reinstates your roof to a fully mortgageable standard.
We provide the exhaustive technical documentation, ventilation proofs, and structural certificates required by major UK mortgage lenders and insurance companies.
High winds and severe weather can cause immediate, hazardous defects. Our team acts fast across the Midlands to make your property safe and watertight.
Rapid Asset Protection: Temporary tarpaulins and structural bracing are deployed immediately to prevent internal water damage.
Insurance Liaison Documentation: We supply detailed, itemised technical reports alongside comprehensive cost estimates. This transparent evidence simplifies the insurance claim process, providing your provider with exact clarity on required works.
We never sub-contract our roofing services. Every stage of your repair is handled by our in-house, safety-trained professionals.
A qualified surveyor inspects your roof externally and internally via the loft space. We examine tiles, flashing, valleys, timbers, gutters, and current insulation performance.
You receive a comprehensive cost breakdown detailing the exact materials, technical standards, and project timelines. We operate with a strict no-hidden-extras policy so you know exactly what to expect.
Safety is our absolute priority. Our in-house team erects secure, fully compliant scaffolding and edge protection tailored to your property. This ensures a safe working environment that meets all HSE guidelines, protecting both our technicians and your home before any structural work begins.
Our team executes the repairs in strict compliance with BS 5534 for slating and tiling and BS 5250:2021 for moisture control. Waste removal and structural modifications are managed responsibly by our crew throughout the project.
The completed work undergoes a strict quality check. Once approved, the scaffolding is safely dismantled, the site is cleared completely of any debris, and we issue your official Certificate of Guarantee.
The cost of a repair depends entirely on accessibility, structural timber condition, and the specific materials needed. Replacing an isolated cracked tile requires a different level of labour and equipment than scaffolding a property to overhaul a failing mortar ridge line. We avoid guesswork by providing a precise, written quote following our free structural site survey.
Yes, but it requires specialised oversight. Standard roofers often struggle with this because spray foam bonds tiles, battens, and rafters together. Our dual expertise in technical roofing and insulation means we can safely access the leak point, check for hidden interstitial moisture or timber rot, and complete a durable repair without needing external contractors.
A traditional wet ridge uses cement mortar to secure the apex tiles. This mortar naturally cracks over time due to frost cycles and building movement. A dry ridge system uses mechanical screws and weatherproof unions to fasten the tiles securely to the underlying battens. It provides superior wind resistance and satisfies modern building standards without ongoing maintenance.
