Question 1

How much does it cost to replace a 1,500 sq ft roof in Houston?

Accepted Answer

True material + sub-crew labor cost for a 1,500 sq ft (15 square) roof in Houston runs $5,600–$8,100 for architectural shingles. Typical contractor quotes come in at $7,800–$13,000 after overhead, insurance, profit, and commission.

Question 2

Why is there such a big spread between true cost and contractor quote on a 1,500 sq ft roof?

Accepted Answer

On a roof this size the markup stack — overhead, general liability + workers comp insurance, profit margin, and sales commission — typically adds 40–60% on top of true cost. Larger roofs amplify the absolute dollar gap. Knowing the underlying number helps you spot quotes that are markup-heavy vs. fair.

Question 3

What pushes a 1,500 sq ft roof to the high end of the range?

Accepted Answer

Steep pitch (8/12 or higher), multiple stories, complex hip-and-valley geometry, premium shingles (GAF Timberline UHDZ, designer lines), full decking replacement, multiple penetrations or skylights, and step flashing against walls. Each of these adds materials and slows down labor.

Question 4

How long does a 1,500 sq ft re-roof take?

Accepted Answer

A Houston sub-crew can typically tear off and install a 1,500 sq ft asphalt shingle roof in 1–2 days depending on pitch, stories, and weather. Add a day if decking replacement is significant.

Question 5

Can I run this for my exact address?

Accepted Answer

Yes — the calculator above pulls a satellite measurement for any Houston-area address and gives you a true-cost number for your specific home. The 1,500 sq ft figure on this page is a benchmark; your actual roof may be ±10–20% depending on overhangs, hips, and pitch.
