What is roof replacement?
Roof replacement is the complete removal of your existing roofing system down to the deck, followed by installation of new underlayment, flashing, and shingles or panels. Unlike an overlay, a full replacement lets us inspect and repair the decking, correct ventilation issues, and install ice and water shield in compliance with Michigan building code.
- Lifespan: 20 to 70 years depending on material. Asphalt runs 20 to 30 years; metal 40 to 70 years.
- Michigan code: Most homes are limited to two shingle layers. A second layer present requires full tear-off before reinstallation.
- Ice and water shield: Installed at eaves, valleys, and penetrations as required by Michigan building code.
- Completion time: Most residential replacements in Metro Detroit finish in one day with a full crew.
Built into every replacement.
Michigan freeze-thaw cycles, heavy snow loads, and ice dams demand a roof that is installed right. Here is what goes into every iSwitch replacement.
Complete tear-off
Every layer removed down to the deck. No layering over old shingles. No shortcuts that void manufacturer warranties.
Deck inspection and repair
Every board inspected. Soft, rotted, or damaged decking replaced before new material goes down. You receive documentation of what we found.
Ice and water shield
Installed at eaves, valleys, and penetrations. Required by Michigan building code and critical for preventing ice dam leaks through freeze-thaw cycles.
Material selection
Architectural asphalt, impact-resistant, and metal options. You choose the profile, weight, and color. We source what you pick.
50-Year Material & Workmanship Warranty
If our installation fails inside ten years, we return and repair it at no cost. Written warranty paperwork on every job.
One-day installation
Most residential replacements complete in a single day. Your home is dried in and the site cleaned up before our crew leaves.
Tear-off vs overlay: which does your roof need?
An overlay adds new shingles over existing ones. A tear-off removes everything down to the deck. Both are legal in Michigan up to two layers total, but they are not equivalent in performance, lifespan, or code compliance.
| Factor | Full tear-off | Overlay |
|---|---|---|
| Existing layers removed | Yes, down to deck | No |
| Deck inspection | Full inspection included | None |
| Ice and water shield | Installed per Michigan code | Cannot be added |
| Michigan code compliant | Always | Only if under 2 layers total |
| Full manufacturer lifespan | Yes | Reduced 5 to 10 years |
| Best for | Aging or damaged roofs, second layer already present, ice dam history | Single layer in good condition, short-term budget constraint |
Choose a full tear-off when:
- Your roof is 15 or more years old
- A second shingle layer is already present
- You have a history of ice dam leaks
- You are selling the home
- The deck has soft or rotted boards
An overlay may work when:
- Your roof has a single layer in good condition
- You are renting or plan to sell within 3 to 5 years
- Budget is a short-term constraint
- Note: Michigan limits most homes to two layers maximum

FREQUENTLY ASKED QUESTIONS
Common roof replacement questions
How much does a roof replacement cost in Metro Detroit?
Asphalt shingle replacements in Metro Detroit typically run $8,000 to $15,000 for an average-sized home, depending on square footage, pitch, material grade, and any deck repairs needed. Metal roofing replacements start around $15,000. We provide itemized estimates at no obligation before scheduling any work.
How long does a roof replacement take?
Most residential replacements are completed in one day. We arrive with a full crew, remove the old shingles to bare deck, install underlayment and new shingles, and clean up by end of day. Larger or steeper roofs may take two days.
Will my homeowners insurance cover a roof replacement?
If your roof was damaged by a covered storm event such as hail or wind, your homeowners insurance may cover replacement minus your deductible. We document conditions with photos, measurements, and inspection reports so your claim is well-supported. We work alongside your adjuster but do not negotiate claims on your behalf.
What is the difference between a roof overlay and a full tear-off?
A roof overlay adds new shingles on top of existing ones without removing the old layer. A full tear-off removes everything down to bare deck. We perform full tear-offs on every job. Overlays trap moisture, hide deck damage, and shorten the life of the new roof. Most manufacturer warranties require tear-off installation.
How long will my new asphalt roof last in Michigan?
Quality architectural shingles last 25 to 30 years under typical Michigan conditions. Premium shingles are rated for 40 to 50 years. Ice and water shield at eaves and valleys protects against ice dam damage, which extends performance through Michigan winters. Proper attic ventilation also extends shingle life significantly.
Do I need to be home during the replacement?
No. We need exterior access only. We handle permitting, material delivery, and cleanup without requiring you on site. We schedule a final walkthrough with you when the job is complete to confirm everything meets your expectations before we leave.
What does your workmanship warranty cover?
Our 10-year workmanship warranty covers installation defects. If our work fails within 10 years, we return and repair it at no cost. Manufacturer material warranties transfer directly to you and run 30 to 50 years depending on the shingle line selected.
