What Drives Your Cost
What a Complete Scope Includes

Preparation

Full tear-off existing shingles

Removing all old roofing layers allows proper inspection and a clean surface for new materials.

Some contractors install over old shingles to save time, which can hide problems and void warranties.
Decking inspected and repaired

Roof decking must be checked and any damaged wood replaced before new roofing is installed.

Skipping this step can trap rot under new shingles and lead to early failure.
Property protection setup

Tarps and coverings protect landscaping, siding, and windows during tear-off.

Without protection, falling debris can damage plants, siding, or outdoor items.

Materials

Shingle brand and grade specified

Naming the exact shingle product ensures you get the quality and warranty you expect.

Vague descriptions allow contractors to substitute lower-quality shingles.
Underlayment type specified

Underlayment protects your home from moisture beneath the shingles.

Cheap underlayment may not hold up to Midwest weather conditions.
Ice and water shield included

This waterproof barrier protects vulnerable areas like eaves and valleys from leaks.

Skipping this can lead to ice dam leaks in cold climates.
Drip edge installed all edges

Drip edge directs water away from fascia and prevents rot along roof edges.

Some contractors skip drip edge on certain edges to cut costs.
Flashing materials specified

Proper flashing around chimneys and walls prevents leaks at roof transitions.

Reusing old flashing can lead to leaks even with new shingles.

Ventilation

Roof ventilation evaluated

Proper ventilation extends roof life and prevents moisture buildup in the attic.

Ignoring ventilation can cause mold, heat buildup, and premature shingle failure.
Ridge vent or vents installed

Vent systems allow hot air and moisture to escape from the attic.

Some contractors reuse old or inadequate vents instead of upgrading.

Installation

Starter shingles installed properly

Starter strips help prevent wind uplift at roof edges.

Skipping starter shingles can lead to shingles blowing off in storms.
Proper nailing pattern used

Correct nail placement ensures shingles stay secure and meet warranty requirements.

Improper nailing can void warranties and cause early failure.
Valleys properly sealed

Roof valleys handle heavy water flow and must be installed carefully to prevent leaks.

Poor valley work is a common source of roof leaks.
Flashing installed at all penetrations

All roof openings like vents and chimneys must be sealed with flashing.

Missing or poorly installed flashing can cause hidden leaks.

Cleanup

Daily jobsite cleanup included

Keeping the site clean reduces hazards and protects your property during the project.

Magnetic nail sweep performed

A magnetic sweep removes nails from your yard and driveway after the job.

Skipping this can leave dangerous nails around your home.
Debris hauled away

All old roofing materials should be removed and disposed of properly.

Permits and Warranty

Permit included in bid

Permits ensure the roof meets local building codes and is inspected.

Contractors suggesting no permit may be avoiding oversight.
Manufacturer warranty documented

You should receive written proof of the material warranty from the manufacturer.

Labor warranty specified

A labor warranty covers installation issues separate from materials.

Some contractors offer little or no labor warranty.

Questions to Ask Every Contractor
  1. Will you do a full tear-off or install over existing shingles?
  2. What exact shingle brand and model are you bidding?
  3. How will you handle flashing around chimneys and vents?
  4. What ventilation improvements do you recommend?
  5. Will you pull permits and provide warranty documentation?
Permits

Most areas require a permit for full roof replacement. Ask your contractor to pull the permit and confirm inspections will be completed — skipping this can create issues with insurance or resale.
