Cost breakdown
This estimate converts a 3,500 sq ft footprint into roof area using a standard pitch multiplier, adds a moderate waste factor, then applies the installed cost range for 3-Tab Asphalt. It is a planning range, not a contractor bid, but it gives homeowners a fast baseline before comparing local quotes.

What 3,500 Sq Ft Means on a Roof
A 3,500 sq ft footprint is about 35 roofing squares. That is the unit roofers actually quote in, order in, and pay disposal by.
A 3,500 sq ft house is usually hip-heavy with gable accents, a covered patio, and wings at different wall heights. Two-story elevations and a steeper main pitch combine, so staging and safety setup take real hours.
At roughly three bundles per square, plan on about 105 bundles on the shingle delivery.
Waste factor
12-15%. Accent gables and steep-pitch hips on the main body multiply factory cuts and cap runs.
Tear-off and dumpster
One layer assumed. 35 squares runs a 30-yard dumpster or two 20-yard pulls once the porch and patio roofs come into it.
Crew and days (shingles)
6-7 person crew, 3 days
Schedule reality
Permit one to two weeks. Install is about three shingle days, more on steep pitches. Special-order tile or standing seam adds weeks of lead time before day one. Inspection within ten days of completion.
Planning checklist at this size
- Confirm the wall-height transitions between wings. Step flashing at those junctions is the highest warranty-claim zone on big hip roofs.
- Plan material staging across two or three drop points. One boom location cannot serve a whole 35-square footprint efficiently.
- Budget temporary protection for landscaping on multiple elevations. Tear-off debris from two stories travels.
What changes the price?
Pitch and access
Steeper roofs require more safety setup, more labor time, and often more waste.
Tear-off layers
Old shingles, decking surprises, and disposal fees can move the final quote.
Valleys and penetrations
Chimneys, skylights, pipe boots, vents, and valleys add flashing detail and labor.
Material grade
3-Tab Asphalt ranges widely by manufacturer, warranty, color, thickness, fasteners, and trim package.
