A practical guide for Leicester homeowners — written specifically for Leicester's housing stock and roofing conditions.
GRP stands for Glass Reinforced Polyester — commonly called fibreglass roofing. It is a composite material made from layers of fibreglass matting bonded together with polyester resin and finished with a UV-resistant coloured topcoat. On a flat roof, GRP creates a seamless, monolithic waterproof membrane that is rigid, hard-wearing and maintenance-free under normal conditions.
GRP installation requires the deck to be clean, dry and structurally sound. Moisture in the deck will cause delamination — we carry out a moisture survey before specifying GRP on any existing deck. The installation sequence is: deck preparation and primer application; first layer of fibreglass matting wetted out with catalysed resin; second layer of matting; cure period; upstand and trim detail application; final topcoat application. The entire installation must be completed above 5°C to ensure correct resin cure.
GRP installed to a correct specification on a Leicester flat roof has a design life of 25–40+ years. We have inspected GRP installations from the late 1990s in Leicester that remain fully watertight — over 25 years of field performance. The limiting factor is not the GRP membrane itself but the UV-protective topcoat, which may need recoating after 15–20 years to maintain the full design life. A GRP roof installed in 2025 on a Leicester extension should not need replacing until the 2050s at the earliest.
3-layer mineral felt has a design life of 10–20 years on a Leicester flat roof. GRP has a design life of 25–40+ years. Over a 40-year period, one GRP installation is less expensive than two felt replacements even before accounting for the disruption and consequential damage costs of felt failure. Leicester's post-war and 1960s–80s housing stock has a large volume of felt flat roof extensions now at or past design life — GRP replacement is the standard recommendation for all of these.
Yes. The guidance in this article is written specifically for Leicester housing stock — the Victorian terrace belt, the post-war estates, the 1930s suburban stock and the outer Leicestershire towns. National guidance is referenced where relevant but the Leicester-specific context is the primary focus.

GRP resin requires a consistent temperature above 5°C. Leicester winters restrict GRP installation to approximately March–November most years. EPDM is our recommended alternative for urgent flat roof replacement in Leicester winter months.
£80–£120 per m² installed. A typical Leicester rear extension of 20–25 m² costs £1,800–£3,600. Garage roof (15–20 m²) costs £1,400–£2,800. Confirmed in writing after free survey.
Minimal. The topcoat may benefit from recoating after 15–20 years to maintain UV protection. Annual visual inspection to confirm outlet drains are clear. No mechanical maintenance otherwise.
Yes, if the deck is structurally sound and dry. We carry out a moisture survey before specifying GRP over felt. Where deck moisture is elevated, the felt must be stripped first. Installing GRP over wet felt traps moisture and causes premature deck failure.
We cover all of Leicester city and the surrounding Leicestershire area. Free surveys with no call-out fee, written condition report within 48 hours of the visit. We have been working across Leicester and Leicestershire since 2003, carrying out repairs, re-roofing, flat roofing, lead work, chimney work and emergency call-outs across all property types and all LE postcodes.
NFRC registered (verifiable at nfrc.co.uk), £5m public liability insurance, 10-year written workmanship guarantee on all re-roofing work. No work starts without your written acceptance of the written itemised quote. Call 0116 319 1348 Monday–Friday 8am–6pm or Saturday 8am–2pm. Emergency line 24/7.
Every job starts with a free on-site survey. The written quote follows within 48 hours and specifies every element: scope of work, materials by manufacturer name, access method, guarantee period and payment terms. There are no verbal quotes, no time-pressure acceptance conditions, and no costs added on site without your prior written agreement. This is the standard we have operated to since 2003 and the standard we will continue to operate to. If you have had a poor experience with a Leicester roofer in the past, we would welcome the opportunity to demonstrate what transparent, professional roofing practice looks like.
Understanding the roofing terminology in this guide is most useful when applied to the specific housing stock types that make up Leicester's residential roofscape. Victorian terraces in Highfields, Belgrave and South Wigston (1870s–1900s), 1930s semi-detached in Oadby, West Knighton and Evington, and post-war estate housing in Braunstone, Eyres Monsell and Thurmaston each present the concepts in this guide in different forms. The practical application depends on which era of Leicester property you are dealing with.
This guide provides general information. For advice specific to your Leicester property, a free roof survey is the most reliable next step. The survey covers your specific roof elements — tile specification, lead work, mortar details, structural timbers — and provides a written condition report with prioritised maintenance recommendations. This is more useful than general guidance because every Leicester property is different, and the correct specification depends on what is actually present on your roof rather than what is typical for the era.
We carry out free roof surveys across all of Leicester city and the surrounding Leicestershire area. Surveys are available within 3–7 working days with no call-out fee. Written condition report within 48 hours of the visit. NFRC registered, £5m public liability insurance, trading since 2003. Call 0116 319 1348 Monday–Friday 8am–6pm or Saturday 8am–2pm. Emergency line 24/7.
We cover LE1 through LE19 including all city neighbourhoods (Highfields, Belgrave, Stoneygate, Clarendon Park, West Knighton, Evington, Braunstone, Eyres Monsell, South Wigston) and outer areas (Oadby, Wigston, Hinckley, Loughborough, Melton Mowbray, Birstall, Blaby, Syston). If you have a question about a roofing term and how it applies to your specific property, call us and we will give you an honest answer based on your postcode and property type.
