Full tear-off and replacement with premium roofing systems. We handle everything from decking to ridge cap — properly, completely, and with warranty coverage that protects your investment.
When your roof reaches the end of its life — or when repairs simply no longer make financial sense — a full replacement is the right move. Alter Phase delivers complete roof replacement projects with premium materials, thorough deck inspection, and workmanship you can rely on for decades.
We handle everything: full tear-off and debris removal, deck evaluation and repair, new underlayment, flashing, drip edge, ventilation, and the final shingle system — finished with a clean job site and a comprehensive walkthrough.
We physically inspect your roof, attic, and decking. You receive a detailed, itemized estimate with material options, project timeline, and warranty information — no hidden fees.
Old roofing materials are completely removed and properly disposed of. We don't layer over existing shingles — a proper replacement starts clean, so problems aren't buried.
After tear-off, we inspect every inch of your roof deck for rot, moisture damage, or structural weakness. Any compromised decking is replaced before the new roof is installed.
Ice and water shield, synthetic underlayment, new drip edge, and all flashings (valleys, chimney, skylights, vents) are installed to code before any shingles go on.
Your chosen shingle system is installed to manufacturer specifications, ensuring full warranty eligibility. We offer multiple styles, colors, and performance grades to fit your home and budget.
We do a complete walkthrough with you, clean the job site meticulously (including magnet sweeps for nails), and provide all warranty documentation. Your satisfaction is confirmed before we leave.
We offer a range of high-quality roofing systems to match your home's needs, style, and budget.
