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.
