Metal Roofing Materials

Metal roofing covers several distinct systems, and the material choice sets the detailing, the fixing centres and the lifespan. On Ash and Ash Vale properties we work in standing seam zinc and aluminium, box profile sheet and metal tile sheet, and the right one depends on pitch, span and what the structure below can carry.

Zinc and aluminium sheet

Quartz-zinc and pre-weathered zinc are normally specified at 0.7mm or 0.8mm gauge for roofing, laid over a ventilated or warm deck build-up. Zinc moves with temperature, roughly 2.2mm per metre over a 100 degree swing, so clips are set as fixed and sliding zones rather than nailed solid. Aluminium at 0.9mm is lighter and takes a coil-coated finish, which suits coastal-facing elevations and exposed gables.

Box profile and metal tile sheet

Box profile steel sheet, typically 0.5mm to 0.7mm with a polyester or plastisol coating, runs on garages, outbuildings and workshops where the pitch is shallow and the run is short. Metal tile sheet gives the look of a tiled roof at a fraction of the dead load, which matters on older timbers that were never designed for concrete tiles. We check the rafter section and the existing purlin spacing before recommending either.

Matching the material to the structure

Before a material is chosen we survey the deck, the ventilation path and the existing wall plate. Condensation risk is assessed against BS 5250, because a cold metal surface with no clear vapour route is where problems begin. If the substrate needs re-boarding, we say so at survey rather than after the sheets are on order.

Standing Seam Roofing Systems

Standing seam is the system most people picture when they think of a modern metal roof: long panels running eaves to ridge, joined by a raised upstand with no fixing penetrating the weathering surface.

How a standing seam roof is built up

The sequence is the same each time. First the deck is checked and made good, usually 18mm plywood or a proprietary board. Then a separation and breather layer is laid. Panels are formed to width, commonly 430mm or 530mm cover, and set out from a datum so the seams land square on the ridge. Clips are fixed at centres calculated for the wind zone under BS 5534, tightening towards verges and eaves. The seams are then double-locked by machine, and the ridge, verge and abutment flashings are formed last.

Angle standing seam and flat lock

Angle standing seam suits pitches from about 3 degrees where the run is short and detailed carefully. Flat lock panels are used on vertical faces, dormer cheeks and small canopies, where the panel is fully supported and the joint is dressed flat. Both rely on the same principle: the fixing sits inside the joint, never through the face.

Noise and movement in practice

A fully supported metal roof over a boarded deck and insulation is not the drumming tin roof people expect. The board, the separation layer and the insulation between them absorb most of the impact noise from rain. Expansion clicking is normal in the first hot spell and settles as the panels bed in.

Metal Cladding and Façades for Ash & Ash Vale Homes

The same panels that weather a roof will clad a wall, and on extensions and dormers the two are often continuous. Our metal roofing work regularly runs down onto vertical faces so the roof plane and the elevation read as one surface.

Dormers, extensions and gable cheeks

Cladding a dormer in zinc or aluminium removes the awkward junction between tile and render that leaks so often on 1960s and 1970s stock. Panels are set out so the seam spacing on the wall lines through with the roof above. Corners are formed on site with a folder rather than bought in as a generic trim.

Copings, fascias and soffits

Parapet copings are folded from the same coil as the roof, with a drip on both faces and a fall back to the roof side. Fascias and soffits can be finished in matching coated aluminium, which removes repainting from the maintenance list. Fixings are colour-matched stainless, not bright steel, because bright steel bleeds rust down a light-coloured panel within a couple of winters.

Planning and appearance

Most re-covering work on an existing roof is repair or maintenance in planning terms, but a change of material, a new dormer or a property in a designated area can need consent. GOV.UK guidance on building regulations approval sets out when a project needs to be notified, and we tell you at survey which route your job falls under rather than leaving you to find out.

Domestic and Commercial Installations

Metal roofing goes on houses, extensions, garages, workshops, stables and small commercial units, and the specification changes with the building.

Domestic work and living around it

Most of the disruption on a house roof is front-loaded. Scaffold goes up first, usually a day. The strip and deck is the noisy part and happens in a defined block, and we sheet and make watertight at the end of each working day rather than leaving an open deck overnight. Panel forming happens on the scaffold or in the drive, which is steady mechanical noise rather than hammering. Nobody needs to move out, and rooms below stay usable other than during the strip above them. Waste goes into a covered skip or bagged, drives are swept daily, and the site is left tidy.

Commercial and outbuilding work

On box profile work over a unit or workshop, sheets are ordered to length so there are no end laps to leak, and fixings are through the crown with bonded washers at the spacings the profile manufacturer sets. BS 5427 covers profiled sheet practice for roof and wall cladding and we work to it. Where an existing garage roof is asbestos cement, we assess it and advise the compliant route under the Control of Asbestos Regulations 2012. We do not carry out licensed removal ourselves.

Coverage across the area

If you are looking for a metal roofer close to home around Ash, Ash Vale, Ash Green or Tongham, our own roofers are local and can get to you quickly. Whether you need metal roofing in Ash & Ash Vale or metal roofing services Knaphill, we cover the whole area with the same teams.

Rainwater Goods and Roof Accessories for Ash & Ash Vale Homes

A metal roof sheds water fast, and the gutter has to be sized for it rather than inherited from the tiled roof it replaced.

Sizing and seamless aluminium gutter

Outlet and gutter capacity is calculated to BS EN 12056 against the effective roof area and the local rainfall intensity. Seamless aluminium gutter is rolled on site to the exact run, so a 12 metre elevation has no joints along its length and therefore no joints to fail. Brackets go at 800mm to 1000mm centres depending on profile, closer at outlets.

Flashings, snow guards and roof accessories

Abutment flashings, chimney soakers and apron details are folded from sheet to suit the actual opening, and leadwork where it is used follows Lead Sheet Association guidance on sizing and fixing centres. On steeper metal pitches over a door or path, snow guards are worth fitting because a smooth panel sheds snow in one slab.

Accreditations and Manufacturer Approvals

We hold no trade body membership or approved-installer badge, and we do not claim one. What stands behind the work is tenure, insurance and a written guarantee.

What we do hold

• Public Liability Insurance, in force and evidenced on request
• A 25-year written workmanship guarantee on every job, repairs included
• 36 years of Scott's own experience on Surrey roofs, still on the tools and still answering the phone
• Work carried out by our own roofers, never subcontracted out

The guarantee is handed over in writing before the team leaves site, not posted on later.

Standards we work to

Fixing and wind uplift follow BS 5534. Flat and low-pitch build-ups follow BS 6229. Ventilation and condensation control follows BS 5250. Rainwater sizing follows BS EN 12056. Profiled sheet work follows BS 5427. These are the documents that decide clip centres, laps and ventilation gaps, and they are why a metal roof stays tight.

Projects and Case Studies

The work in this area is mostly extension roofs, dormers, garages and outbuildings, with the occasional full house re-cover in standing seam.

Typical jobs in and around Ash

Common pieces of work include a flat or low-pitch extension re-covered in standing seam aluminium, a tired felted garage taken back to deck and re-sheeted in box profile, and dormer cheeks clad in zinc to stop a recurring leak at the render junction. Each one starts with a free survey, including a drone view where the pitch makes it useful, then a fixed price in writing.

How the quote and the job run

Call and a real person answers. We survey, measure and check the deck and ventilation. You get an honest fixed price in writing with no obligation and no charge. If a smaller repair does the job, we say so. Then the work is completed, the site is left tidy and the guarantee is handed over.
