Siding replacement cost by address
Siding is priced per square foot of wall. Your house outline gives the wall length. Add the height, the gable triangles under a peaked roof, and take out windows and doors, and you have the number a contractor measures.

How the estimate works
- Walls. Perimeter of the OpenStreetMap outline × wall height × stories.
- Gables. A gable roof leaves two triangles of wall at the ends: ½ × end width × roof rise. A 30 ft end on a 6/12 roof rises 7.5 ft, so each triangle is about 113 sq ft.
- Openings. Windows and doors aren't sided. The default takes out 15%.
- Price. Net wall area × the installed range for the material, plus removal. The order quantity adds 10% waste, in squares of 100 sq ft.
| Material | Installed, per sq ft | Typical life |
|---|---|---|
| Vinyl | $4–$12 | 30–40 yrs |
| Aluminum | $6–$10 | 25–40 yrs |
| Engineered wood | $7–$12 | 30–50 yrs |
| Fiber cement | $6–$15 | 50–75 yrs |
| Wood (pine, fir) | $5–$15 | 20–40 yrs |
| Cedar | $6–$16 | 20–40 yrs |
| Steel | $7–$16 | 40–70 yrs |
| Stucco | $7–$17 | 50–80 yrs |
Worked example
A 60 × 30 ft one-story ranch with 9 ft walls has 1,620 sq ft of wall (180 ft × 9 ft). The two gable ends add 225 sq ft. Taking out 15% for windows and doors leaves 1,568 sq ft, or about 18 squares to order. Vinyl at $4–$12 plus removal: $7,400–$22,000.
What moves a siding quote
- Tear-off. $0.7–$2 per sq ft. Check that every bid includes it.
- What's behind it. Rotten sheathing or framing found once the old siding is off is billed separately.
- Trim, soffit and fascia. Often quoted as separate line items by the linear foot.
- Height and detail. Second stories, dormers and many corners slow the crew down.
Doing the roof too? Price it with the roof estimate by address and the gutters with the gutter cost tool.

Frequently asked questions
How do I measure my house for siding?
Multiply each wall's length by its height, add the gable triangles (half the end width × the roof rise), then take out windows and doors. Add about 10% for waste when ordering.
How much does it cost to replace siding?
HomeGuide puts installed siding at about $4–$13 per sq ft in 2026: vinyl $4–$12, fiber cement $6–$15, engineered wood $7–$12. Removal of the old siding adds $0.7–$2 per sq ft.
How many squares of siding do I need?
Net wall area plus 10% waste, divided by 100. A one-story 60 × 30 ft ranch needs about 18 squares.
Does a hip roof need less siding?
Yes. A hip roof has no gable walls, so the siding stops at the eaves on all four sides.
Is fiber cement worth it over vinyl?
It costs more but lasts longer. HomeGuide gives fiber cement a 50–75 year life against 30–40 for vinyl.
