Installation guide · What to expect
Three to four days, no surprises.
A typical residential metal roof installation takes three to four days. Every project follows the same structured process — from contract signing to final walkthrough — with transparent payment terms and direct communication with Colum throughout. No hidden change orders, no disappearing crews, no upsells.
Step by step
Ten stages, in order.
i.
Contract & payment terms
Once you approve your quote, the contract is signed with a transparent three-stage payment structure: a 10% deposit (flexible and customer-led), a second payment on the day materials are delivered, and the final payment upon completion. Any known issues — rotten decking, chimney work — are discussed and priced upfront on the contract.
ii.
Scheduling & communication
You receive a few days' notice before the crew arrives. Scheduling is weather-dependent, and we communicate proactively by phone, text, or email. If weather delays a start date, you are informed immediately.
iii.
Material delivery & crew arrival
Materials are coordinated for delivery on the same day the job starts. You choose where the materials are placed on your property. The crew arrives at 8:00 AM ready to begin work.
iv.
Roof preparation
Approximately 80% of installations are layover jobs — installed directly over existing asphalt shingles, manufacturer-approved. During a layover, edge shingles, ridge caps, curled shingles, and moss are removed in a cutback process. For the remaining 20% requiring a tear-off, the old roofing is removed down to the deck.
v.
Underlayment & waterproofing
Synthetic underlayment membrane is applied across the entire roof surface. For tear-offs, ice and water shield is added for additional protection against moisture penetration in Ontario's freeze-thaw climate.
vi.
Flashings & detailing
All flashings are installed before the metal panels: chimney flashings (custom bends, sometimes requiring stone cutting), skylight flashings, sidewall and front-wall flashings, and plumbing stack boots (rubber-to-metal sealed). The most detail-intensive phase, critical for long-term waterproofing.
vii.
Metal roofing system installation
Panels installed according to manufacturer specifications. Snow guards are added where needed — above front doors, walkways, hot tubs, and barbecue areas — to prevent sudden snow slides.
viii.
Gutter assessment
Gutters are assessed as part of every project. You receive an honest recommendation on whether to replace them before or after the roof work, depending on their condition. Never a pressure upsell — just practical advice.
ix.
Cleanup & site safety
A dedicated ground crew member handles cleanup throughout the entire installation — not just at the end. A magnetic sweeper collects any stray screws and nails from the lawn, driveway, and walkways. At the end of each day, the site is locked down with a full safety check.
x.
Final walkthrough
Colum personally inspects every completed installation. This final walkthrough ensures every detail meets standards before the project is signed off and your final payment is collected.
Layover vs. tear-off — side by side.
Most homeowners qualify for a layover installation, which saves time and cost. The comparison:
| Factor | Layover (~80% of jobs) | Full tear-off |
|---|---|---|
| Existing shingles | Remain in place — cutback process for edges, ridges, moss | Fully removed down to the deck |
| Underlayment | Synthetic membrane | Ice & water shield + synthetic |
| Warranty | Same manufacturer warranty | Same manufacturer warranty |
| Cost | Lower — no disposal costs | Higher — labour + disposal |
| Timeline | Faster | Additional 1–2 days |
Layover is manufacturer-approved by Ideal Roofing. The only difference is cost — both deliver the same warranty and long-term performance.
Weather handling and property care.
Weather communication
The forecast is monitored closely. If weather threatens mid-installation, the site is secured and tarped to protect your home. Tools are locked down and the crew returns when conditions clear. You’re kept informed at every stage.
Property protection
Gardens and landscaping are protected — platforms are built over delicate areas when needed. A dedicated ground crew member handles cleanup throughout the day, and a magnetic sweeper collects stray fasteners from lawns, driveways, and walkways.
No surprise change orders
A thorough pre-inspection catches most issues before work begins. Rotten decking is discussed and priced upfront on the contract. Chimneys needing masonry work are referred to a qualified subcontractor. You know the full scope before the first panel is installed.
Living at home during installation
You can stay home throughout. Noise levels are comparable to an air gun — noticeable but not overly invasive. Pets and vehicles are fine on the property. Just communicate with the crew if you need to leave during the work day.
Installation questions
What homeowners ask about install day.
How long does a metal roof installation take?
Most residential metal roof installations in Simcoe County take 3 to 4 days. Simple jobs (small roof, straightforward geometry) can be completed in 2 days. Larger or complex projects with multiple dormers, skylights, or steep pitches may take 5 to 7 days.
Can metal roofing be installed over existing shingles?
Yes. Approximately 80% of our installations are layover jobs — installed directly over existing asphalt shingles. This is manufacturer-approved by Ideal Roofing and does not affect warranty coverage. The only difference between a layover and a tear-off is cost. During a layover, edge shingles, ridge caps, curled shingles, and moss are removed in a cutback process before the new roof is applied.
What happens if it rains during my roof installation?
Weather is closely monitored throughout every project. If rain arrives mid-installation, the crew secures the site with tarps, locks down all tools and materials, and returns when the weather clears. Your home is never left exposed.
How much noise should I expect during installation?
The noise level during a metal roof installation is comparable to an air gun — noticeable but not overly invasive. Most homeowners find it manageable and remain in their homes throughout the process.
What are the payment terms for a metal roof installation?
Select Metal Roofing uses a transparent three-stage payment structure: a 10% deposit when the contract is signed (flexible and customer-led), a second payment on the day materials are delivered, and the final payment upon project completion. There are no hidden fees or surprise charges.
What if rotten wood or other issues are found during installation?
A thorough pre-inspection is conducted before work begins to catch potential issues early. If rotten decking or sheathing is identified, it is discussed and priced upfront on the contract — not added as a surprise change order.
Do I need to move my car or protect my garden during installation?
Your vehicle can remain in the driveway — just let the crew know if you plan to leave during the day. Gardens, bushes, and landscaping are protected during the installation process, with platforms built over delicate areas when needed. A dedicated ground crew member handles cleanup throughout the day.
