What HD Sharman does

HD Sharman Ltd (trading as Sharmans) is a privately held UK manufacturer of metal roof and gutter refurbishment systems, founded in 1985 by Harold Sharman and headquartered at High Peak Works, Chapel-en-le-Frith. The company's single-vendor portfolio is organised around four registered-trademark product families: Plygene Gutterline (a BBA-certified thermoplastic gutter lining system with 25-year guarantee and 39+ years of independent Florida UV testing), Seamsil (a silicone-based cut edge corrosion and bolt encapsulation system using GE Alkoxy technology), Delcote (an inorganic AA fire-rated full roof coating with 10- and 25-year guarantees), and Delglaze (a polyurethane rooflight refurbishment coating). A complementary cladding line (Tikkurila Temadur 20/50) and an ancillaries range (GutterBond, Rooflock tape, Leister and Steinel installation tooling) round out the offering, and a new RoofCare 24/7 remote monitoring service was launched in 2025.

The business sells primarily through a national Approved Contractor Network of 1,000+ certified installers (12 training days per month, field audits as a prerequisite to releasing guarantees), supported by direct inside-sales via 'Get a Quote' and 'Book a Site Survey' flows, free condition reports, two CPD-accredited education programmes (Metal Roof Refurbishment; Why Gutters Fail), and an NBS Source listing that feeds specifications directly into surveyor workflows. Revenue is generated through project-based sale of refurbishment systems at quote-based pricing (10-25 year guarantees), e-commerce sales of ancillaries and installation tools, and managed services through the Approved Contractor programme. Target customers are UK industrial and commercial building owners (warehouses, factories, distribution centres, self storage, transport depots), supported by three primary personas: roofing contractors, property/building managers, and building surveyors/specifiers. In 2025 the company joined Premier Technical Services Group Ltd (PTSG) as part of a change of ownership.

Broad incumbents

• Renolit: European manufacturer of single-ply roofing membranes (including Renolit ALKORPLAN) and waterproofing systems used in commercial roof refurbishment. Competes with Sharmans for commercial roofing projects, particularly where full-membrane replacement is specified over coating-based refurbishment.
• IKO: Global manufacturer of roofing membranes, waterproofing and insulation systems with a UK commercial roofing business. Overlaps with HD Sharman on commercial roof refurbishment but with a much broader product portfolio spanning flat-roof, pitched and built-up systems.
• Carlisle Construction Materials: Major US-headquartered manufacturer of single-ply roofing membranes (EPDM, TPO, PVC) with a growing UK presence. Competes indirectly for commercial roof refurbishment specifications through alternative system architectures versus Sharmans' liquid coatings and gutter lining.
• Sika: Global construction chemicals and waterproofing major with roofing, sealing and coating systems that overlap Sharmans' Seamsil and Delcote ranges. Much broader portfolio and global reach, but competes for the same commercial roofing refurbishment specifications in the UK.

Direct peers

• Bauder: UK-based manufacturer of flat and pitched roof systems including single-ply, bitumen and liquid waterproofing. Overlaps with HD Sharman in BBA-certified commercial roofing systems, UK contractor training, and the specifier-driven specification workflow for industrial and commercial buildings.
• Axter: UK-focused manufacturer of bituminous and single-ply roofing membranes with BBA-certified systems. Competes with Sharmans for commercial roof refurbishment specifications, though primarily focused on flat-roof membrane systems rather than metal-roof coatings.
• Tor Coatings: UK-based manufacturer of roof refurbishment and liquid waterproofing coatings (now part of RPM International's Tremco/Illbruck group). Directly comparable product portfolio to HD Sharman's Delcote and Seamsil ranges, serving UK commercial roofing contractors and specifiers.
• Polyroof Products: UK manufacturer of liquid-applied flat roof waterproofing systems for commercial and industrial buildings. Comparable BBA-certified systems, UK contractor network and project-based commercial sales motion, with overlapping customer segments in property and facilities management.
• Kemper System: Manufacturer of liquid-applied waterproofing and roof coating systems with a strong UK presence. Directly competes with Sharmans' Delcote and Seamsil silicone-based coating systems in cut edge corrosion repair and full roof refurbishment.
• Triflex: European manufacturer of liquid-applied roofing and waterproofing systems used for commercial roof refurbishment. Directly comparable to Delcote and Seamsil in terms of cold-applied liquid systems and BBA-equivalent certifications in the UK market.
