FAQs
Why should I combine a roof replacement with an insulation upgrade?
Replacing the roof is the ideal time to improve insulation because the roof deck is already exposed. This allows installers to fit high-performance insulation boards or rolls without extra disruption, seal thermal bridges, and add ventilated membranes. Doing both tasks together saves on labour costs, ensures the new roof meets current Part L Building Regulations, and immediately cuts heat loss by up to 25 %, lowering energy bills and carbon emissions.
What insulation materials are best for Manchester’s climate?
For pitched roofs we typically recommend rigid PIR (polyisocyanurate) boards or mineral wool. PIR offers outstanding thermal resistance (λ≈0.022 W/mK) in a relatively thin layer—useful when rafter depth is limited. Mineral wool is cost-effective, non-combustible (Euroclass A1) and excellent for acoustic performance, ideal for homes near busy roads. In flat roofs, high-density PIR or EPS boards topped with a waterproof single-ply or GRP membrane give both insulation and weather protection against Manchester’s frequent rain.
Will I need planning permission for a roof replacement with added insulation?
Most roof replacements with insulation upgrades fall under Permitted Development provided the finished roof height does not increase by more than 150 mm and materials are similar in appearance. However, if your property is listed, in a conservation area, or you plan to raise the ridge height, you will need consent from Manchester City Council. Our surveyor checks local constraints and, if required, helps prepare and submit the planning application.
How long does a typical roof replacement and insulation upgrade take?
A semi-detached house with an average roof area of 80–100 m² usually takes 5–7 working days from scaffold erection to final clean-down, weather permitting. Day 1: scaffold and material delivery; Day 2–3: strip off old tiles and felt, inspect/repair timbers; Day 3–4: install new insulation, breathable membrane, battens; Day 4–5: lay new tiles or slates, fit flashings; Day 6: gutters, verge and ridge finishing; Day 7: snagging, waste removal, final inspection. Larger or more complex roofs may take longer—your quotation will include a customised schedule.
How much does a roof replacement with upgraded insulation cost in Manchester?
Costs vary with roof size, pitch, material choice and insulation depth. As a guide, a standard three-bed semi with concrete interlocking tiles and 150 mm mineral wool insulation costs £7,500–£10,000 + VAT. Premium slate and PIR board upgrades may range from £12,000–£16,000. These figures include scaffolding, waste disposal, building control sign-off and a 10-year workmanship guarantee. We provide free, no-obligation surveys and itemised quotes so you know exactly what you’re paying for.
What warranties and certifications do you provide?
All our roof replacements come with a 10-year insurance-backed workmanship warranty and manufacturer warranties of 30–40 years on tiles or slates. Our insulation products carry BBA certification and fire safety ratings. We are TrustMark and NFRC-accredited and register every project with Manchester Building Control, supplying a completion certificate that confirms compliance with Part L (energy efficiency) and Part C (moisture).
