Frodsham has a designated town conservation area with a published appraisal, and that appraisal is unusually useful to anyone planning a new roof — because it says, in the council's own words, what the roofs of the town are supposed to look like.
Roofline Solutions provides professional new roof installations in Frodsham, including complete re-roofing, replacement roofs, new slate roofs and new tiled roofs.
What ends most roofs is not the covering. It is the fixings, the battens and the underlay - all of which are present across the whole roof, all the same age, and all of which reach the end of their working lives together.
Frodsham's conservation area was originally designated in 1973 and extended in 1977, with an appraisal adopted in 2006. Unlike a bare designation, an appraisal is a document you can read: it defines the boundary and describes what the area's special character is taken to consist of.
On roofs it is specific. The appraisal records that blue and grey Welsh slate roofs predominate, at varying but not very steep pitches, with some thatch and plain terracotta tile.
Two things follow from “not very steep pitches”. Slate tolerates lower pitches than most tiles do, so a roof that works perfectly well in slate may sit below the minimum pitch for the tile someone wants to put on it. And where the pitch is shallow, the headlap has to increase — which means more slates per square metre, and a quotation that has quietly reduced the headlap to lower the slate count is cheaper for a reason you would not accept if it were spelled out.
None of this makes a like-for-like re-slate difficult. Putting slate back on a slated roof raises no planning question at all. It is a change of covering that needs the conversation.
A complete re-roof means stripping back to the rafters and rebuilding every layer: new breathable underlay, new treated battens at the correct gauge, the new covering fixed to the manufacturer's specification, new lead, mechanically fixed ridge and hip, and ventilation at eaves and ridge. Anything materially less is a different job.
Concrete tiles are coloured with a pigmented surface layer rather than through the body of the tile, so a concrete roof twenty-five years on does not look as it did on day one. Clay takes its colour from the material and holds it. Whether that matters depends on how long you intend to be in the house.
The country of origin matters less than people think. Spanish slate spans an enormous range from excellent to poor, and a well-graded Spanish slate is a better product than an ungraded slate from anywhere. The declared grading tells you far more than the map does.
Replacement is also the moment when everything else on the outside of the house becomes cheap. Fascias, soffits, guttering, chimney repointing and flashing renewal all need the same scaffold. Bundled they cost comparatively little; done separately each one carries its own access.
Look at the exposed lower edge of the units with binoculars. Clean, sharp edges mean the surface is intact. Ragged, flaking or crumbling edges mean frost is getting into a covering that has become porous, and that is not cosmetic.
What you have already spent on a roof tells you something about the roof. It tells you nothing about what you should do next: that money is gone either way, and the only question with any bearing on your finances is which option costs less from today onward.
Going from tile to slate is the easy direction. Slate is lighter than concrete tile and works at lower pitches, so both of the constraints that block the reverse change are on your side. The argument against is cost and time, not physics.
On a larger renovation there is a second regulatory threshold worth knowing about. Beyond the ordinary rule for a renewed roof, work to more than a quarter of the whole building envelope - walls, roof, floors, windows and doors together - counts as a major renovation and brings wider requirements into play.
A new pitched roof on an extension has to be tied into the main roof, and that junction - an abutment, a valley, or both - is where the detailing matters. It is worth asking how it is being formed rather than assuming.
Most people assume a new roof needs planning permission. Usually it does not, and the reason is stronger than permitted development. Under section 55 of the Town and Country Planning Act 1990 — which applies in England and Wales alike — work that does not materially affect the external appearance of a building is not development at all. A like-for-like re-roof therefore falls outside the planning system rather than relying on rights granted by the Town and Country Planning (General Permitted Development) (England) Order 2015.
A change of covering is a different question, because it may materially affect external appearance. That is where conservation area status starts to matter: even with no Article 4 direction in force, inside a conservation area the “not materially affecting external appearance” test is applied a good deal more tightly, so swapping slate for a visibly different tile can need permission on its own merits. Cheshire West and Chester Council can confirm the position for a specific address at no cost.
Frodsham has a designated town conservation area, originally designated in 1973 and extended in 1977, with an appraisal adopted in 2006. The appraisal records that blue and grey Welsh slate roofs predominate, at varying but not very steep pitches, with some thatch and plain terracotta tile.
Frodsham's 2006 conservation area appraisal recommended that an Article 4 direction be considered. A recommendation in an appraisal is not the same as a direction actually being made, so the current position is worth confirming with the council.
If the building is listed, listed building consent is a separate requirement from planning permission and it does cover roof coverings. That should be resolved before the work is priced rather than after.
Building regulations are separate from planning, and they are the part that catches people out. Replacing a roof covering renews a thermal element, and where more than 50% of that element's surface area is renewed — or the work forms part of a major renovation — regulation 23 of the Building Regulations 2010 requires the whole element to be brought up to current thermal standards, so far as that is technically, functionally and economically feasible. A patch repair is not a re-roof and does not trigger it, and neither does a roof over unheated space such as a detached garage, an outbuilding or a carport.
For a roof in an existing dwelling, Approved Document L Volume 1 gives a U-value of 0.16 W/(m²K) for the renovated element. On an ordinary cold loft that is reached by topping up the insulation at ceiling level rather than insulating the roof slope; where the roof space is a habitable room, the insulation has to go at rafter level instead, which is a bigger job and should be priced as one.
The work is signed off in one of two ways: a notification to building control — either Cheshire West and Chester Council's own service or a Registered Building Control Approver — or self-certification by a roofer registered under a competent person scheme, such as NAPIT or CompetentRoofer, now run by the National Federation of Roofing Contractors as the NFRC Competent Person Scheme. Whichever route is used, you should receive a compliance certificate at the end — keep it, because a buyer's solicitor will ask for it.
If your property is inside the conservation area boundary, we will tell you what that means for the covering before quoting rather than after.
