Roofing in Market Harborough carries a constraint that is easy to miss until the scaffold is up.
In Little Bowden the Article 4 direction covers front elevation alterations, and a roof covering is part of the front elevation as far as the street is concerned. Changing the material on a front slope, or altering the detail at the eaves or the verge in a way that reads differently from the ground, is not a neutral act there. We check before quoting rather than after, and we quote what will actually get through rather than the cheapest option.
Technically the town divides the usual way. The older housing is slate or clay tile on cut timbers, with the failures concentrated at valleys, abutments and chimney stacks rather than in the field of the roof. A valley patched for twenty years will keep failing at the same point until the lead is renewed properly.
The estate housing is concrete tile on trussed rafters, where the verge and the flashings are the weak points after several decades, and a dry verge system fixes a recurring gable end leak permanently for far less than the re-roof people assume they need.
Re-covering triggers a Building Regulations requirement to look at insulation, and we arrange that inspection and see it through to sign off. More on our roofing page.
