How Much Does a New Roof Cost in Stretford?

Stretford's housing is dense terraced and semi-detached property from the late Victorian and inter-war periods, and those two halves behave differently on a roofing job. The late Victorian terraces are much what you would expect. The inter-war semis have a feature that surprises people when the quotations arrive.

The Hipped Roof, and Why It Costs More

Inter-war semis were very often built with hipped roofs rather than gables — four sloping planes meeting at a ridge and running down to hips at the corners, instead of two planes with a vertical gable wall at each end.

It is a more attractive shape and it sheds wind better. It is also more expensive to cover, for reasons that have nothing to do with area.

Every hip is a cut line

On a gable roof, whole tiles or slates run from one end to the other and the only cutting is around a chimney. On a hipped roof, every single course has to be cut on the rake where it meets the hip — on both sides, on every hip. On a typical semi that is four hip lines, each needing every course cut and fitted individually.

More furniture per square metre

Hip tiles or hip irons run the full length of each hip, and they have to be fixed, aligned and finished. That is material and labour a gable roof simply does not have.

Waste

Cutting produces offcuts, and a hipped roof produces a great deal more of them than a gabled one of the same area. That shows up in the material order.

It is harder to do partially

A hipped roof is a closed form — all four planes read as one object. Replacing one plane leaves a visible difference in a way that doing one side of a gabled terrace does not. In practice this pushes hipped roofs towards being done in full.

The Terraced Half of Stretford

Different considerations, mostly practical rather than geometric.

• Continuous roof planes. Your roof is often part of one unbroken slope across several houses, which raises the question of how new covering meets old at the party line and how that junction is weathered.
• Party walls. Where work involves cutting into or rebuilding above a party wall — a stack on the party line, for instance — the Party Wall etc. Act 1996 may require notice. Straightforward re-covering up to the line normally does not.
• Access. Dense terraced streets often mean no rear access, which governs where the scaffold stands, where the skip goes and how much time goes into moving material.
• Footway licences. Where a scaffold has to stand on the pavement, a licence is needed from Trafford Council.

The Planning Position — and Why It Is Street-Specific

This is one of the few places in Cheshire and south Manchester where we would not give a town-wide answer, because there is not an honest one.

Trafford Council makes Article 4 directions in two categories, one of which covers development affecting areas and buildings of historic interest. Whether roofing rights are withdrawn on a particular Stretford street therefore depends on which direction, if any, applies there. Two streets a few hundred metres apart can be in different positions.

So the honest advice is: ask about your address. Trafford Council can confirm it at no cost, and it is worth doing before you commission quotations if you are considering any change to how the roof looks.

What is not street-specific is the position on a like-for-like renewal. Putting the same covering back 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 — anywhere, under any direction. If the building is listed, listed building consent applies separately and does cover roof coverings.

The Rest of the Variables

• Area, and shape. As above — shape does more work here than most people expect.
• The existing covering, and how long it takes to strip.
• The condition of the timbers. The genuine unknown on any roof. Agree the rate for defective timber in advance and ask to be shown it before it is replaced.
• The covering chosen. Usually the largest single decision.
• Chimneys and valleys. Every junction needs lead, and lead work is slow.
• What else gets done under the same scaffold — fascias, soffits, guttering, chimney repointing.

Building Regulations

Separate from planning and applicable to every re-roof. Replacing a covering renews a thermal element, and regulation 23 of the Building Regulations 2010 requires the thermal performance of a renewed element to be improved where technically and economically feasible. Approved Document L Volume 1 gives a roof U-value of 0.16 W/(m²K) for existing dwellings.

On late Victorian and inter-war housing this is a substantial upgrade, and it is part of the job rather than an optional extra. Sign-off is through building control — Trafford's own service or a Registered Building Control Approver — or by self-certification where the roofer is registered under a competent person scheme.

Comparing Quotations

Three quotations only tell you something if all three are pricing the same roof. On Stretford's stock, start with the questions about shape and about the house next door — those are where quotations diverge most and where standard lists say nothing.

Shape

• How many hip lines does this roof have, and has the cutting on them been priced rather than covered by an area rate?
• How are the hips being finished — a mechanically fixed dry hip system, or bedded in mortar as the original was?
• How much cutting waste is allowed for in the material order?

The house next door

• If only one half of a pair is being done, how is the junction at the party line being weathered — soakers or a secret gutter, or mortar?
• How close a match to the neighbouring half is realistically achievable?
• Would the contractor price both halves together, and what would that save?

Then the scope

• Scaffold included, and for how long — plus a footway licence if one is needed?
• Battens renewed, or the figure assuming the existing ones stay?
• Underlay named, and breathable?
• Lead renewed at chimneys, abutments and valleys, at what code?
• Ventilation provided at eaves and ridge?
• How the roof reaches the required insulation standard?
• Fascias, soffits and guttering in, or separate?
• The rate for defective timber, agreed in writing?
• Who certifies the work, and whether that fee is included?
• The guarantee — what, how long, backed by whom?
