Footprint is not roof area
This is where roofing estimates go wrong, and they go wrong in the direction that leaves you short on a Saturday.
A 44 × 52 ft footprint is 2,288 ft² on the ground. At 10/12 the roof over it is 2,978 ft² — the pitch factor is 1.302, which is √(1 + (10/12)²). Pure geometry, no fudge factor.
Order off the footprint and you are 6.9 squares short before waste is even counted.
Squares and bundles
34.3 squares with 15% waste for a hip roof — 103 bundles at three per square.
Waste is not one number. A simple gable cuts only at the rakes. A hip roof cuts along every hip. A cut-up roof with valleys and dormers throws away a fifth of what you buy, and no amount of careful planning changes that.
The two lines everyone forgets
Starter: 2 bundles for 192 ft of eave and rake. Hip and ridge cap: 6 bundles for 109 ft.
These are separate products, not field shingles cut down. Using field shingles as starter voids most manufacturers' wind warranties, which is discovered at the claim rather than at the purchase.
Underneath
4 rolls of synthetic underlayment, and 750 ft² of ice-and-water shield at the eaves — 24 inches inside the exterior wall line, which is what the IRC asks for where it applies. Check whether your jurisdiction requires it.
79 lb of roofing nails at four per shingle, or lb at six for a high-wind zone.
Two things to price before you decide it is DIY
Tear-off: about 9,419 lb of old shingle to strip and skip.
And access. Above 8/12 a roof stops being walkable for most people, and roof jacks, planks or scaffolding cost real money that belongs in the estimate before you decide this is a DIY job.
Notes
- **Footprint is not roof area, and the gap is bigger than people expect.** A 44 × 52 ft footprint is 2,288 ft² on the ground but **2,978 ft²** of roof at 10/12. Ordering off the footprint leaves you 6.9 squares short — and that is before waste.
- The pitch factor is √(1 + (rise/12)²). There is no estimate in it and no manufacturer fudge — it is the hypotenuse. 10/12 gives 1.302.
- 15% waste for a hip roof: every hip is a run of angled cuts. A simple gable wastes least because the only cuts are at the rakes; every hip and valley adds a run of angled cuts that produce offcuts nothing else uses.
- Starter and cap are separate purchases, and they are the two lines that get left off estimates. 2 bundles of starter for 192 ft of eave and rake, 6 bundles of hip and ridge for 109 ft. Using field shingles as starter voids most manufacturer wind warranties.
- At 10/12 this is not a walkable roof for most people. Roof jacks and planks, or scaffolding — and that cost belongs in the estimate before you decide whether this is a DIY job.
- Tear-off is the other half of the job. A single layer of asphalt shingle weighs 200–350 lb per square, so this roof carries about 9,419 lb of old material to remove and skip.
