The short answer
A roof replacement runs in a clear sequence: scaffolding goes up, the old covering is stripped, the timbers and battens are checked and renewed, a new membrane and covering are laid, and the job ends with detailing, a tidy-up and sign-off. Expect noise, dust, a skip outside and scaffolding around the house for the duration — typically a few days to a couple of weeks (see how long it takes). A good contractor protects the property, keeps it watertight overnight, and leaves the site clean.
A re-roof is a big, visible job, and knowing the order of events makes it far less daunting. The work is methodical: roofers do not simply “put a new roof on” in one go but progress through stages, keeping the roof weatherproof at each step. This guide walks through what happens from the first morning to the final inspection, the disruption to expect, and the simple things you can do to prepare. It is general information about a typical project.
What to expect at a glance
- Scaffolding around the house for the whole job
- Skip outside for the old covering
- Noise & dust during working hours
- Roof kept watertight overnight
- Site left clean at the end
The stages of a re-roof
Most full replacements follow the same sequence, whatever the property:
- Scaffolding — erected first so the team can work safely; usually half a day to a day.
- Strip and clear — old tiles or slates, felt and battens removed and skipped.
- Inspect the structure — rafters and battens checked; any rotten timber repaired before re-covering (a common point for extra cost — see new roof cost).
- Membrane and battens — a modern breathable membrane and new battens fitted.
- Lay the new covering — new tiles or slates laid up each slope.
- Detailing — ridge, hips, valleys, flashing around chimneys, and ventilation fitted.
- Tidy-up and sign-off — site cleared, roof inspected, scaffolding removed, and any Building Regulations certification issued.
The disruption to plan for
A re-roof is disruptive but manageable. There will be scaffolding around the house for the duration, which affects access and parking. Expect noise — stripping the old roof and nailing battens is loud — during normal working hours, and some dust and debris, particularly during strip-off. A skip will usually sit outside for the old materials. Inside, you may notice dust in the loft and the odd vibration. None of this is unusual, and a considerate contractor minimises it with dust sheets, careful working and a daily clear-up.
How to prepare your home
A few simple steps make the job smoother. Clear the loft of anything precious or fragile, or cover it, as dust and the odd fragment can come through during strip-off. Move cars off the drive so scaffolding and the skip can be sited and the team can load and unload. Take down or secure wall-mounted items inside that sit against the ceiling, as vibration can dislodge them. If you have pets, plan for the noise. And agree access and working hours with the contractor in advance so there are no surprises. Beyond that, the team handles the rest.
What a good contractor does
The marks of a professional re-roof are consistent: a written quote and schedule, the right safety measures and scaffolding, the roof kept watertight at every stage, daily tidying, clear communication if hidden problems are found, and proper sign-off at the end — including any Building Regulations certificate and a workmanship guarantee. Knowing these standards helps you judge a contractor; our guide on how to choose a roofer sets out what to look for before the work begins.

Frequently asked questions
Do I need to move out during a roof replacement?
No — in almost all cases you can stay in the home during a re-roof. The work is external, and the roof is kept watertight overnight. You should plan for noise, dust and scaffolding, and clear or cover the loft, but moving out is not normally necessary.
Will my house be left open to the weather?
It should not be. A professional roofer strips only what they can make watertight each day and protects the open roof against rain. If a contractor leaves a roof exposed during bad weather, treat it as a warning sign about their standards.
How much mess does a re-roof make?
There is noise, dust and debris, especially during strip-off, and a skip usually sits outside. A considerate contractor uses dust sheets, tidies daily and clears the site fully at the end. Clearing or covering the loft beforehand limits dust inside.
