How this calculator works
Every figure above comes from the formula below, applied to the assumptions listed. Nothing is looked up from a hidden table — you can reproduce the result by hand.
Formula
sloped area = footprint × slope factor, where slope factor = √(rise² + 144) ÷ 12
base cost = sloped area × material rate per sq ft (installed)
tear-off adds sloped area × $1–$2 per sq ft
total = (base + tear-off) × complexity multiplier
Assumptions & limits
- Asphalt shingles are costed at $4.50–$11 per sq ft installed, the widest range of any material here because it spans basic 3-tab through premium architectural and designer shingles.
- Weight is roughly 200–450 lb per square, which almost any existing roof structure already carries — no framing check is normally needed.
- Typical service life is 15–30 years, so this is the one material where a second layer over the old roof is sometimes permitted instead of a tear-off.
- Installed rates per sq ft of roof surface: asphalt shingles $4.50–$11, cedar shake $7–$14, flat membrane $5–$12, metal standing seam $9–$16, tile $12–$25, slate $15–$30. These are 2026 national ranges covering material and labour.
- Tear-off and disposal adds $1–$2 per sq ft and is assumed to be a single existing layer. A second or third layer costs more.
- The complexity multiplier is 1.0 simple, 1.1 moderate, 1.25 complex, standing in for hips, valleys, dormers, chimneys and steep-slope access.
- The split shown is roughly 42% materials, with the rest labour and disposal. Real splits vary by market and by how tight the roofing labour supply is.
- This is a budgeting range, not a bid. It excludes deck replacement, structural repair, gutters, skylights and permit fees — sheathing rot found after tear-off is the most common overrun.
Worked example
A 40 × 30 ft footprint at 6:12 pitch, asphalt shingle, moderate complexity, tear-off included
- Sloped area = 1,200 × 1.1180 = 1,342 sq ft → 13.4 squares
- Material and labour = 1,342 × $4.5 to $11 = $6,039 to $14,762
- Tear-off = 1,342 × $1 to $2 = $1,342 to $2,683
- Moderate complexity × 1.1 → $8,119 to $19,191
Result:About $8,119 to $19,191 installed for a asphalt shingle roof of this size. Get three itemised local bids.

How much does a asphalt shingle roof cost?
Asphalt shingles are the default residential roof in the US because they balance a low installed price with easy, fast installation. Architectural (dimensional) shingles cost a little more than basic 3-tab but last longer and look better, which is why most homeowners choose them today.
As an installed all-in figure, a asphalt shingle roof typically runs $4.50–$11 per square foot. On a 1,957 sq ft roof (about a 1,750 sq ft home at a 6:12 pitch) that is roughly $9,000–$21,500 before any unusual features. The estimate above lets you set your exact roof size, pitch, complexity and tear-off to tighten the range.
cost = roof area × $4.50–$11/sq ft (× complexity) + tear-off · roof area = footprint × slope factor
Typical service life for asphalt shingle is 15–30 years. Once you have a target number, compare it against real local quotes before you commit — and if you're sizing materials for a DIY job, the roofing material calculator gives you squares, bundles and a shopping list.

Frequently asked questions
How much does a asphalt shingle roof cost?
A asphalt shingle roof typically runs $4.50–$11 per square foot installed, all-in. On a 1,957 sq ft roof that works out to roughly $9,000–$21,500. Asphalt shingles are the default residential roof in the US because they balance a low installed price with easy, fast installation. Enter your own roof size and pitch above for an estimate.
How long does a asphalt shingle roof last?
A asphalt shingle roof has a typical service life of about 15–30 years, depending on the product grade, your climate and how well it is installed and maintained. You're paying for low up-front cost, fast install, wide color choice.
What drives the cost of a asphalt shingle roof?
The main factors are roof size, pitch, complexity (hips, valleys, dormers and skylights), and whether the old roof is torn off — tear-off and disposal add about $1–$2 per square foot. Steeper and more complex roofs cost more because the work is slower and needs more safety equipment.
Is a 3-tab or architectural shingle better?
Architectural (dimensional) shingles cost roughly 20–40% more than 3-tab but carry longer warranties, resist wind better and are what most US homeowners now choose. 3-tab is thinner, flatter-looking and increasingly used only on rentals and outbuildings. The $4.50–$11 per sq ft range above spans both, so use the lower half for 3-tab and the upper half for architectural or designer profiles.
Can I put new shingles over the old roof?
Sometimes. Asphalt is the one common material where a second layer is occasionally permitted, and skipping tear-off saves roughly $1–$2 per sq ft. But it adds weight, hides deck rot, shortens the new roof's life and voids some manufacturer warranties, and most codes cap a roof at two total layers. Set tear-off to No above to see the saving, then decide with a roofer who has actually looked at the deck.
How many shingle bundles are in a square?
Three bundles cover one square (100 sq ft) for standard 3-tab and most architectural shingles. Heavier designer and luxury shingles run four or five bundles per square, so check the wrapper before ordering. To size bundles rather than price the job, use the roofing material calculator.
Will my homeowners insurance pay for a new roof?
Insurance generally covers roof replacement when the damage comes from a sudden covered peril — a storm, hail, fallen tree or fire — minus your deductible, and often pro-rated for the roof's age on older policies. It typically will not pay to replace a roof that has simply worn out from age or lack of maintenance. Document storm damage with photos and get a contractor's inspection before filing a claim.
