How long does a new roof take?

What decides the timescale

The main factors are:

• Size and shape: hips, valleys, dormers and multiple roof slopes take longer than a simple gable roof.
• Covering: large concrete tiles cover ground quickly; small plain tiles and natural slate take longer to lay.
• Condition underneath: damaged battens are always replaced, but rotten rafters or boards add time.
• Weather: strong wind and heavy rain stop work on exposed roofs.
• Extra work: chimney repairs, new leadwork, fascias, soffits and gutters are often done at the same time.
• Access: scaffolding must be erected before work starts and removed afterwards.

The typical stages of a re-roof

Scaffolding goes up first so the roof can be worked on safely and edges are protected. The old tiles or slates are then stripped, usually a section at a time, along with the old battens and underlay.

With the rafters exposed, any damaged timber is dealt with. New breathable membrane is laid and new battens fixed, which is the stage shown in several of our recent job photos. The roof is weather-protected at this point even before tiles go on.

Tiles or slates are loaded out across the roof and laid, then the ridge, hips and verges are finished. Leadwork around chimneys and walls, ventilation and any roofline work follow. Finally the site is cleared and the scaffold is taken down.

Will my home be exposed to the weather?

A careful roofer strips only as much as can be protected. Membrane and battens are fitted promptly, and any open areas are covered at the end of each day, so the house is not left open to rain overnight.

Can I stay at home during the work?

Most homeowners stay in the property during a re-roof. Expect noise during stripping and some dust in the loft. Clearing valuables from the loft and keeping cars away from the drive while tiles are being removed is sensible.

What can cause delays

Weather is the most common cause. Hidden problems such as rotten timbers or unsound chimney stacks can add time once the roof is opened up. Material supply for particular tiles or slate can also affect start dates, so check this when you accept a quotation.

Planning can also matter. Some properties, such as listed buildings or homes in conservation areas, may need consent for changes to the roof's appearance. Check this before work is booked.

Flat roofs and repairs

Flat roof replacements on garages and extensions are generally quicker than whole pitched roofs because the area is smaller, though they need dry conditions. Straightforward repairs to tiles or flashing are often completed in a single visit.

Questions to ask before work starts

Ask how long the job is expected to take, when the scaffold will go up and come down, how the roof will be protected overnight and what happens if damaged timber is found. Confirm what is included, such as leadwork, ventilation and roofline, and how waste will be removed. Also ask whether the gutters and downpipes will be checked while access is available. Clear answers make it easier to plan around the work and avoid surprises once the old roof is opened up.
