How a roof replacement actually runs, week by week

A roof replacement is one of the few jobs where the house stays occupied while its most important layer is opened up to the weather. Done properly, it is a tightly sequenced operation. Here is how a typical family-home roof runs on our contracts in Sweden and Latvia.

Week 0 — inspection and quote

Before anything is priced, we inspect the roof from the inside and out: rafters, battens, underlay, ventilation, chimney and valley flashings. Many “roof problems” are actually ventilation or flashing problems, and replacing tiles without fixing them wastes the whole investment.

You receive a written fixed quote with the scope stage by stage — stripping, carpentry repairs, underlay, battens, covering, flashings, gutters — and a start date we commit to.

Week 1 — scaffolding, stripping, structure

Scaffolding goes up with proper edge protection. The old covering comes off slope by slope — never the whole roof at once — so the house is never left open overnight. This is when hidden damage shows itself: soft rafter ends, sagging battens, old felt turned to dust. Anything found is photographed and priced as a written variation before work continues.

Week 2 — underlay, battens, covering

New breathable underlay and counter-battens go on, then the covering — tile or standing seam. On standing-seam roofs we fabricate flashings on site so every valley, dormer cheek and chimney apron is fitted to the actual geometry, not a catalogue approximation. Integrated solar, if specified, is mounted in the same pass so the roof plane stays unbroken.

Week 3 — details, gutters, handover

Ridges, verges, chimney flashings and gutters are finished, and the site is cleared daily — not only at the end. You get photo updates through the whole job, and at handover we walk the roof line together, close the snag list, and you receive the written warranty: 10 years on workmanship.

A straightforward family-home roof typically takes two to three weeks on site. Weather can add days; poor planning is what adds weeks.
