Protecting the character of period homes and listed buildings demands careful roofing that respects original fabric while meeting modern standards. In Midhurst and across the South Downs, many properties sit within conservation areas or carry listed status, so getting consent, materials and methods right is essential. Here is how we approach sensitive conservation roofing to deliver durable results that look authentic and perform for decades.
Understanding consent for heritage roofing
Before any work begins, it is vital to check whether you need permission. Listed Building Consent is usually required for roof alterations on listed properties, even for like-for-like works. In conservation areas, planning consent may be needed if you plan to change materials, alter roof lines or add rooflights. We recommend early conversations with the local planning authority and the conservation officer. In Midhurst this often involves the South Downs National Park Authority and Chichester District Council.
We support homeowners and estates with clear documentation that helps consent move smoothly. This typically includes a photographic condition survey, a schedule of works, samples of proposed materials and a simple heritage statement that explains significance and impact. Where relevant, we can coordinate ecology checks such as bat surveys, as protected species can influence timing and method.
Good practice during approvals
Agree the scope and details in writing, specify materials by source and size, and outline fixings and ventilation. Set out access arrangements, temporary weather protection and how salvage will be handled. This keeps stakeholders aligned and protects the fabric from unnecessary risk.
Choosing materials that respect your building
Authenticity begins with the right materials. Our first step is to identify what is already there, then match it carefully. Salvage is often the best route. We set aside sound tiles and slates for reuse, topping up with reclaimed or suitable new stock.
Clay tiles: Many local roofs use Wealden clay. Hand-made or sand-faced tiles with the correct camber and colour blend maintain the familiar Sussex character. We match size, nib position and patina as closely as possible, using copper or stainless nails to guard against corrosion.
Natural slate: Where slate is original, we look for like-for-like thickness and tone. British slate is preferred where feasible. If alternatives are considered, we agree samples with the conservation officer to ensure visual compatibility.
Stone and special coverings: Some roofs include Horsham stone or distinctive ridge details. Limited new supply can make salvage essential. We catalogue and relay original elements wherever condition allows.
Leadwork: Lead to BS EN 12588, correctly detailed with the right Code for each task, is vital for long-term performance. We follow the Lead Sheet Training Academy guidance and apply patination oil where appropriate to control early weathering.
Mortars and underlays: Lime mortars, often NHL2 or NHL3.5 depending on exposure, provide breathability and flexible bedding for ridges and hips. Vapour-permeable underlays and traditional eaves ventilation help control condensation without trapping moisture in old timbers.
Sustainability and careful sourcing
We favour reuse, quality reclaimed stock and responsibly sourced new materials. Sorting, grading and blending ensure a natural finish that sits comfortably with adjacent roofs and the wider streetscape.
Methods suited to sensitive conservation work
Heritage roofing is as much about method as material. We record the roof before stripping, number special pieces and protect features such as bargeboards, pargetting and joinery. Temporary roofing keeps the structure dry if the programme or season demands.
Fixings comply with BS 5534 for wind uplift while remaining discreet. Where ridges were traditionally mortar bedded, we now add concealed mechanical restraint to satisfy current standards without changing the appearance. Lead valleys, soakers and flashings are detailed to proven rules of thumb for laps, drip heights and ventilation. We never apply foam spray insulation to rafters on historic roofs, as this can trap moisture and harm timbers.
Balanced ventilation in line with BS 5250 helps preserve the roof structure. Insulation upgrades are considered carefully, using breathable build-ups that respect the building’s hygrothermal behaviour.
Safety and access on heritage sites
Designed scaffolds, gentle material handling and clean work areas reduce risk to masonry, gardens and interiors. Where public areas are close by, we plan deliveries and traffic management to minimise disruption.
Working in Midhurst and the South Downs
Midhurst’s mix of medieval, Georgian and Victorian buildings calls for local knowledge. We understand exposure on hilltop plots, the palette of nearby roofs and the expectations of the South Downs National Park. Our relationships with local reclaim yards and specialist suppliers help us source authentic stock promptly.
