Roofing for a 1,500 Sq Ft House

Roofing a 1,500 Square Foot Home

A 1,500 sq ft home is the median-sized American house. With a typical 5/12 pitch, the actual roof area is approximately 1,720 square feet, translating to 17.2 roofing squares. This is a substantial project that most homeowners hire professionals for.

Cost Comparison by Material

Material	Cost per Sq	Total (17.2 sq)	Lifespan
3-tab shingles	$70–$90	$1,200–$1,550	15–20 years
Architectural shingles	$90–$130	$1,550–$2,240	25–30 years
Metal roofing (standing seam)	$300–$500	$5,160–$8,600	40–70 years
Slate	$600–$1,500	$10,320–$25,800	75–100+ years

Professional installation for architectural shingles: $7,500–$12,000 total including tear-off and labor.

When to Replace vs. Overlay

Building codes in most areas allow up to two layers of shingles. Overlaying saves $1,500–$3,000 in tear-off costs but adds weight to the structure and may void manufacturer warranties. If you already have two layers, or if the existing decking has damage, a full tear-off is required.

Pro Tips

• Get 3 quotes minimum. Roofing prices vary 30–50% between contractors. Ask each for a written scope including ventilation, flashing, and ice barrier specifics.
• Time your project for off-season. Late fall and early spring often have lower labor costs. Avoid scheduling in July/August when demand peaks.
• Check for insurance coverage. If damage prompted the replacement, document with photos before any work begins. Many insurance claims cover full replacement minus deductible.
