How Long Does a New Roof Take to Fit?

Most new pitched roofs on a typical Sunderland semi or terrace take 3–7 working days to strip and re-cover, weather permitting. A small flat roof can be done in 1–3 days, while a large detached house, complex roof shape or bad weather can push the job to 1–2 weeks.

What “a new roof” actually involves

When people say a new roof, they usually mean a full re-roof: stripping the old tiles or slates back to the timbers, replacing the underlay (felt) and battens, renewing flashings, and re-covering with new or salvaged tiles. That is a bigger job than a repair or a partial re-cover, so the timeline is longer. If you only need a section replaced, or you are weighing up your options, our guide on whether to repair or replace your roof is a good place to start.

Typical timelines by roof type

Every roof is different, but these indicative ranges give a realistic picture for a Sunderland home. They assume reasonable access and dry-enough weather.

Roof / job	Typical time	Notes
Small flat roof (garage, extension)	1–3 days	EPDM, GRP or felt over a modest area
Terraced house, pitched re-roof	3–5 days	Smaller footprint, simpler shape
Semi-detached, pitched re-roof	4–7 days	The most common job we see
Large detached / complex roof	1–2 weeks	Multiple valleys, dormers, steep pitch

These are indicative UK ranges to help you plan, not a quote. An exact timeline and price needs a free survey of your actual roof. For more on budgeting, see our roof cost guide and the page on new roofs.

A typical re-roof, day by day

Here is roughly how a standard pitched re-roof on a semi tends to run. Your job may combine or split these stages.

• Day 1 – Set up and strip. Scaffold is checked, the work area is protected, and the old covering is stripped off and cleared. Felt and battens come off so the team can see the timbers.
• Day 2 – Repairs and prep. Any rotten timber, rafters or fascia issues spotted during the strip are dealt with. New breathable underlay and battens go on.
• Days 3–5 – Re-cover. Tiles or slates are loaded out and laid, with new flashings around the chimney, valleys and abutments. Ridge and verge are finished, ideally with a dry ridge system for a longer-lasting, mortar-free finish.
• Final day – Finish and clean up. Flashings sealed, everything checked over, debris removed and the site left tidy. Scaffold is usually struck a day or two later.

What speeds the job up – or slows it down

The single biggest variable in the North East is the weather. We work Monday to Saturday, but heavy rain or high winds make stripping and working at height unsafe, so the team will pause and protect the roof rather than press on. That can add days to the calendar even though the work itself has not slowed.

Other factors that affect how long a new roof takes:

• Roof size and shape. A simple rectangle is far quicker than a roof with multiple valleys, hips, dormers or a steep pitch.
• Access and scaffolding. Tight terraces, back lanes and tricky access take longer to set up safely.
• Hidden repairs. Rotten battens or damaged timbers only show once the old covering is off; fixing them properly is worth the extra time.
• Material lead times. Specialist or matched tiles and slates sometimes need ordering in.
• Crew size. A bigger team can shorten the on-site time on a larger roof.

Do you have to move out?

No. A re-roof is external work, so you can stay in your home throughout. Expect noise during the day, especially during the strip, and dust around the property. The team keeps walkways clear and tidies the site each day. If you spot a problem mid-job, such as a sudden leak during a downpour, our emergency roofing team can make things safe quickly.

How to get an accurate timeline

The honest answer to “how long will my roof take?” comes after someone has actually looked at it. A free survey lets a roofer measure up, check access, spot likely hidden repairs and give you a realistic schedule and a clear price — not a number plucked over the phone. If you are still deciding whether you even need a full re-roof, the signs you need a new roof guide will help. Flat roof instead? See flat roofs for typical timings on those.
