What to Expect

What Actually Happens
During a Roof Tear-Off

Tear-off is the part of the project that determines whether your new roof is built on a sound foundation. Here's exactly what we do — and why every step matters.

Step 1: Setup

Property Protection First

Before a single shingle comes off, we protect your home and landscaping. This is where most contractors cut corners and where homeowners notice it later.

Tarping + Plant Protection

Tarps over landscaping, AC units, pool surfaces, and walkways before any tear-off begins.

Dump Trailer Staged

Dump trailer positioned to collect tear-off debris cleanly — not piled in your yard or driveway.

Magnetic Sweep Setup

Magnets staged for ongoing nail collection throughout the project.

Crew Briefing

Crew walks the project together — scope, hazards, ground rules — before work begins.

Step 2: Tear-Off

Removing the Existing Roof

Full tear-off — not overlay. We remove every shingle, every fastener, and every piece of old underlayment.

Shingle Removal

All existing shingles removed and loaded directly into the dump trailer.

Underlayment Removal

Existing underlayment (usually 30-lb felt) removed. We don't install new underlayment over old.

Flashing Removal

Old flashings removed for reinstall with new ones. Reused flashings are usually a sign of cut corners.

Fastener Removal

Old nails pulled or driven flush. Loose fasteners are a future leak source.

Ongoing Cleanup

Magnetic sweeps run throughout — not just at the end.

Debris Disposal

All tear-off material hauled away by the end of the day. No piles left on your property.

Get Your Roof Tear-Off Quoted Properly

No overlay shortcuts. Real tear-off, real deck inspection, real system install.

Step 3: Deck Inspection

What We Look For Underneath

This is the step that makes tear-off worth doing. Once the old roof is off, we inspect every inch of decking before the new system goes down.

  • Soft spots from previous water intrusion

  • Rot around penetrations and valleys

  • Sagging deck panels indicating structural issues

  • Improper original nailing patterns

  • Areas where deck panels need replacement

Step 4: Dry-In

Getting the Home Watertight Same-Day

We never leave a roof opened up overnight. By end of day, the home is dried-in with synthetic underlayment and leak barriers installed.

Synthetic Underlayment

Installed across the full deck — tear-resistant, water-shedding, and built to outlast the shingle layer.

Leak Barriers

Ice & water shield in valleys, around penetrations, and at eaves — the spots that fail first.

FAQs

Common Questions

We don't recommend it, and we don't do it. Overlays trap heat and moisture, add weight on the deck, prevent deck inspection, and can affect manufacturer warranty eligibility. Every Westmark project is a complete tear-off.

We address it before installing the new system. Decking repair is sometimes a small additional line item — but it's the right thing to do, and we'll always show you what we found.
