Architectural$4–$9 / sq ft installed

What a complete price should include

A useful estimate separates the base installation from preparation, removal and finishing. Check that every bid states the same scope before comparing totals.

  • Exact shingle line, color, starter and ridge products
  • Tear-off layers, disposal and deck inspection
  • Underlayment, ice barrier, valleys, flashings and vents
  • Fastening specification, permits, cleanup and warranty registration

Cost drivers that change the quote

Shingle system

Three-tab, architectural and luxury shingles differ in weight, profile, wind rating and price. A complete compatible accessory system can also affect enhanced warranty eligibility.

Tear-off and deck condition

Multiple layers, brittle material and rotten sheathing add labor and disposal. Ask for a per-sheet deck repair rate before the roof is opened.

Pitch and penetrations

Steep slopes, valleys, chimneys, skylights and wall intersections slow work and increase flashing. A simple square rate should be adjusted to actual roof planes.

DIY versus professional installation

Roof replacement exposes workers to falls and the house to weather. Underlayment and flashing errors may stay hidden until a leak. A qualified roofer should coordinate tear-off, temporary dry-in, code, ventilation and manufacturer requirements.

Questions to put in the written quote

  • Roof-plane measurement, pitch, squares and waste
  • Shingle and accessory product names with coverage
  • Tear-off, deck repair, flashing and ventilation scope
  • Weather plan, fall protection, permits and labor/material warranties

Frequently asked questions

How many bundles make a roofing square?

Three bundles are common for many asphalt shingles, but coverage varies. Use the selected product label instead of assuming.

Does a roof quote include rotten plywood?

Usually the amount cannot be known before tear-off. The quote should state included allowance or a clear unit price for replacement.

Can new shingles cover old shingles?

Some jurisdictions and systems allow limited overlays, but deck inspection, weight, surface condition, flashing and warranty requirements may favor tear-off.

Sources and update basis

Prices vary by location, access and specification. Market-price references establish the planning range; official and industry technical references support the safety, measurement and scope guidance. Neither replaces a local written quote, product instructions or applicable code.
