How Long Does a Full Roof Replacement Take?
A full re-roof is a bigger job than a repair, and the timeline depends on the size of the roof, the material, and the weather. Here’s a realistic guide.

Quick Answer
Most full roof replacements on an average semi-detached or terraced home take between 5 and 10 working days, weather and access permitting.
The Stages of a Roof Replacement
Scaffolding and Setup
Scaffold is erected around the whole property for safe access – typically a single day’s work before roofing itself begins.
Strip-Off
The old covering, felt and battens are stripped back to the rafters, usually completed within a day for an average-sized roof.
New Felt, Battens and Covering
A breathable membrane and new battens are fitted, then new tiles or slates laid – typically 2-5 days depending on roof size and complexity.
Ridge, Flashing and Detailing
Ridge tiles, valleys and flashing around chimneys are finished, usually completed within a day.
Clear Down and Final Check
The site is cleared, gutters checked, and a final inspection walked with you before the scaffold comes down.
What Affects the Timeline
Roof size and pitch complexity, material availability (a bespoke tile or slate match can add lead time), weather delays, and whether structural timber work is needed underneath all affect how long a re-roof actually takes.
Living in the House During a Re-Roof
Most re-roofs are completed with the house fully occupied throughout. Expect noise and the property covered in scaffold for the duration, but the inside of the house is rarely disrupted unless structural timber work is needed.
Frequently Asked Questions
Can a roof replacement be delayed by weather?
Yes – strip-off and covering work can’t happen safely in heavy rain or high wind, so a job can run a day or two over in poor weather.
Do I need to move out during a re-roof?
No, almost all re-roofs are completed with the house occupied throughout.
How far in advance should I book a re-roof?
Popular slots, especially before winter, get booked up – it’s worth arranging a survey and quote well ahead of when you need the work done.
