Job takeoff

Eaves and rainwater takeoff

Fascia, soffit, gutter, hangers and guard — five trades off one total eave length.

A takeoff is the trade word for the shopping list a job produces — every material, and how much of each, worked out by its own cited calculator.

Gutter CalculatorGutter sections for every run. The calculator divides one run, so this row's eave length is yours plus 4 m (13 ft) for each gutter run after the first: each run is cut from its own sections and rounds up on its own. The count is never short; it is at most one section over for each run after the first in metric, and at most two in imperial. The row's own eave length and downspout figure describe that longer figure, not your runs.

Gutter Hanger Spacing CalculatorHangers at the standard 36 in (about 900 mm) centres. The calculator hangs one run, so this row's eave length is yours plus 6 ft (1.83 m) for each gutter run after the first: two spaces, for that run's own end hanger and its own rounding up. The count is never short, and at most one over for each run after the first; the row's own eave length and hanger centres describe that longer figure, not your runs. Where snow or ice loads the gutter, use 24 in (about 600 mm), which the hanger calculator offers; the same 6 ft is then three spaces, one more spare per extra run.

Estimates, not a quote. Each row gives its base, the allowance on top, the adjusted figure and what to order; change an allowance on the row, or open its reasoning to see every figure it rests on. A trade's own page carries what it does not cover — open the one you are about to order against.

About this job

The eave is the only part of a house where five different products are all measured along the same line, which makes it the cheapest assembly on the site to get right and the one most often ordered piecemeal. Fascia, soffit, gutter, hangers and guard all follow the total eave length, every eave added together; only the soffit needs a second dimension, only the hangers need a spacing, and the gutter and hangers also need the number of separate gutter runs, because each run has its own ends and is cut from its own lengths.

Soffit is the row that carries the ventilation. A boxed eave with no air path starves whatever is venting at the ridge, and a ridge vent with no intake will pull its air from inside the house instead — which is warm, wet air arriving in a cold roof space. Vented soffit panels are the same length of material and a different product, so the quantity does not change and the outcome does.

Hanger spacing is not decorative. It is what decides whether a gutter full of water in February keeps its fall or sags in the middle and holds a puddle, and it tightens in a climate that gets snow sliding off the roof above it.

The order this happens in

Quantities do not tell you the sequence, and on this job the sequence is where the money goes wrong.

  1. Replace any rotten rafter tails before the fascia hides them.
  2. Fix the fascia to a line, not to the rafter ends — the ends are rarely in one plane.
  3. Fit the soffit into the fascia and the wall channel, keeping the ventilation path clear.
  4. Set the gutter to a fall towards the outlet, checked with a level rather than by eye.
  5. Hang at the spacing, closer where snow or a long run demands it.
  6. Fit the guard last, and only after the gutter has been tested with a hose.

What this takeoff does not cover

  • Downpipes, outlets, shoes and everything below the gutter.
  • Rafter tail repair, which is the commonest hidden cost on this job.
  • The roof covering and its drip edge, which have to be lifted and relaid at the eave.
  • Corners, stop ends and mitres — counted by number rather than by length.
