Our Process

How Shingle Roof Replacement Works

1

Remove Old Roof

Full tear-off of existing shingles down to the decking โ€” never installed over an old roof.

2

Inspect Decking

Decking is checked board by board for rot or water damage.

3

Replace Damaged Decking

Any rotted or weakened sections are replaced with new exterior-grade plywood before anything else goes on.

4

Install Ice & Water Shield

Manufacturer-matched ice and water shield membrane in leak-prone areas like valleys and eaves.

5

Install Underlayment

Synthetic underlayment across the full roof deck for a secondary moisture barrier.

6

Install Starter Strip & Shingles

Starter strip, field shingles, and ridge cap โ€” all from the same manufacturer system for full warranty eligibility.

7

Flashing & Ventilation

New drip edge, step, and counter flashing, plus proper ridge and soffit ventilation.

8

Final Walkthrough

We walk the finished roof with you and clean up the site before calling the job done.

Shingle Roofing FAQ

Common Questions

Designer shingle lines like GAF Camelot II are heavier, more dimensional asphalt shingles styled to resemble natural slate or wood shake, typically offering a more premium look and stronger warranty tiers than standard 3-tab shingles.
Both are top-tier manufacturers we're certified with. The right choice usually comes down to warranty coverage, budget, and style preference โ€” we'll walk you through both during your estimate.
Yes. Any deteriorated or weakened plywood decking is identified during tear-off and replaced with new exterior-grade plywood before shingles go down.
