Tile is the broadest category in roofing — the range between the cheapest and the dearest option is very wide, and on some Frodsham properties part of that range is not available to you.
"Tile" covers a lot of ground. A concrete interlocking tile and a handmade clay plain tile are both tiles, and the difference between re-roofing a house in one and the other is substantial in both material and labour. Before a cost figure means anything, it has to be attached to a specific tile.
In Frodsham there is a second question stacked on top of the first, because the town has a designated conservation area with a published appraisal, and inside its boundary the range of appropriate tiles is narrower than it is outside.
The workhorse of post-war British roofing and the lowest-cost route. Large units with an interlocking edge, single-lapped, so relatively few per square metre and quick to lay. Modern ranges are much better looking than their reputation suggests. The known drawback is that the colour is a surface treatment which weathers over time, so a concrete roof twenty years on does not look like it did on day one.
The same principle in fired clay. More expensive as a material, similar to lay, and the colour is in the clay rather than on it, so it holds up. A reasonable middle path where appearance matters but plain tiles are out of reach.
Small, flat, double-lapped tiles — the traditional covering across much of England. Many more units per square metre than any interlocking tile, and correspondingly much slower to lay. That labour is the main reason plain tiling sits at the top of the cost range. What you get for it is the appearance and the detailing: plain tiles can be dressed around hips, valleys and swept features in ways interlocking tiles cannot.
The plain tile format in concrete. Cheaper than clay per unit but with the same high labour content, which limits the saving. Heavier than clay, which matters on an older roof.
| Concrete interlocking | Clay interlocking | Clay plain | Concrete plain | |
|---|---|---|---|---|
| Material cost | Lowest | Moderate | Highest | Moderate |
| Units per m² | Fewest | Few | Many | Many |
| Labour | Lowest | Low | Highest | High |
| Colour over time | Weathers | Holds | Holds | Weathers |
| Weight | Heavy | Moderate | Moderate to heavy | Heaviest |
| Minimum pitch | Lowest | Low | High | High |
| Period appearance | Range-dependent | Good | Best | Fair |
Every tile carries a manufacturer's minimum pitch, below which it is not warranted — because below it, wind-driven rain gets pushed back up the lap faster than the tile can shed it. Plain tiles need a notably steeper pitch than interlocking tiles.
This is worth measuring before falling in love with a tile. It is particularly worth measuring on a rear outrigger or a later extension, which frequently sits at a shallower pitch than the main roof and may need a different covering as a result.
Concrete tiles are heavy — concrete plain tiles especially so. On the older sandstone and brick property in Frodsham, the roof structure was framed for whatever it was originally built with, which was frequently slate. Putting a significantly heavier covering onto that frame is a structural question and should be treated as one rather than assumed.
Where the structure is marginal, the answer is a lighter tile rather than strengthening, in most cases. Modern lightweight interlocking tiles cover a lot of ground here.
Frodsham has a designated town conservation area with a published appraisal. Unlike a bare designation, an appraisal is a document you can actually read: it defines the boundary and describes what the area's special character is taken to consist of, which normally includes the prevailing roofing materials and details.
For a homeowner choosing a tile, that is genuinely useful. It tells you what the authority considers characteristic before you commission a single quotation, rather than after you have accepted one. Cheshire West and Chester Council can confirm whether a specific address falls inside the boundary and point you to the appraisal.
It is worth being clear about what designation does and does not do. It does not make a like-for-like re-roof a planning matter: renewing a tiled roof in the same tile does not materially affect external appearance, so under section 55 of the Town and Country Planning Act 1990 it is not development at all, inside a conservation area or out of it. What designation affects is a visible change of material.
If the property is listed, listed building consent applies separately and does cover roof coverings. That is resolved before pricing, not after.
Renewing a tiled roof renews a thermal element. Regulation 23 of the Building Regulations 2010 requires the thermal performance of that element to be improved where technically and economically feasible, and Approved Document L Volume 1 gives 0.16 W/(m²K) for a roof in an existing dwelling. The work is notified to building control at Cheshire West and Chester Council, or self-certified by a roofer registered under a competent person scheme.
Apex Roofing does not publish a price list, because the honest range on a tiled re-roof is too wide for a published figure to help anyone. What we will do is look at the roof, measure the pitch, check the structure, tell you which tiles are genuinely available to you, and put it in writing.
We will specify a tile that suits the pitch, the structure and — where it applies — the conservation area.

Clay holds its colour and generally suits older property better; concrete costs less and, in interlocking form, lays faster. Neither is better in the abstract. On a period property inside a conservation area, clay is the more likely answer. On modern housing outside it, concrete is perfectly reasonable.
Yes. Frodsham's conservation area has a published appraisal, and Cheshire West and Chester Council can point you to it. It sets out the boundary and describes the character of the area, which usually includes what the prevailing roof materials are. It is a more useful starting point than guessing.
Because there are far more of them. Plain tiles are small and double-lapped, so a square metre takes many units, each individually laid. Interlocking tiles are large and single-lapped. The labour difference is often bigger than the material difference.
No. A like-for-like renewal does not materially affect the external appearance of the building, so under section 55 of the Town and Country Planning Act 1990 it is not development at all — and that holds inside the conservation area as well as outside it. A change of covering is a different question, as is a listed building.
