Step-by-Step Guide On How To Install Metal Roofing

A metal roof is not difficult to install when you follow some steps.

Step 1: Check Local Codes and Permits

Before starting, you have to ensure your project complies with Calgary building regulations.

Some areas require permits. There are colour or style regulations in some HOAs (Homeowners Associations). Failing to do this step may lead to fines or eviction in the future.

You can review Alberta building standards through the Government of Alberta.

Step 2: Measure the Roof Carefully

Wrong measurements lead to wasted panels.

Measure:

Roof length
Roof width
Slope and pitch

Add extra material for cuts and mistakes. Accurate measurements save time and money.

Step 3: Remove the Old Roofing (If Needed)

Some metal roofs go over shingles. Some roofs require full removal.

Remove old roofing if:

Shingles are damaged
Roof deck is uneven
Moisture is trapped

A clean surface ensures better performance.

Step 4: Inspect the Roof Deck

Before laying metal panels, check the roof deck carefully. Look for soft or rotten wood. Replace any damaged areas.

A well-built foundation is a guarantee that your roof is not going to collapse too quickly. This step can not be neglected and little work today will save much trouble hereafter.

Step 5: Install the Underlayment

Place the underlayment flat on top of the roof. The underlayment is your second line of defense.

It protects against:

Moisture
Condensation
Ice dams

In Calgary, an ice-and-water shield is strongly suggested in areas around eaves.

Step 6: Add Drip Edge and Flashing

Drip edge regulates water flow.

Install it:

Along roof edges
Over the underlayment

Flashing is added around:

Chimneys
Vents
Skylights

This eliminates water leaks and damage. Minor holes lead to major problems in the future.

Step 7: Install Metal Panels

This is the core step in how to install metal roofing.

Start at the bottom edge, one side first. Draw a chalk line along the panels. Overlap properly. Fix with screws and rubber washers:

Do not over-tighten
Keep spacing even

The panels are supposed to overlap to prevent the entry of water.

Step 8: Fasten Screws the Right Way

Wrong screw placement causes leaks.

Always:

Use manufacturer-approved screws
Place screws on flat areas
Tighten until snug, not crushed

Rubber washers must seal properly.

Step 9: Install Ridge Caps and Closure Strips

Cover the roof peak with ridge caps.

Use closure strips to:

Block wind-driven rain
Stop insects
Reduce noise

Secure evenly for a clean finish. This step finishes the roof’s top seal.

Step 10: Final Inspection and Cleanup

Do a full walk-around.

Check for:

Loose screws
Sharp edges
Gaps

Remove metal scraps. Clean gutters.

An inspection check guarantees the performance in the long term.

DIY vs Professional Installation

Installing a metal roof can be done yourself, but it’s not always easy.

DIY works if:

The roof is simple and small
You have some experience
You follow safety rules carefully

Professional installers are better if:

The roof is steep or complex
You want it done faster
You need to follow Calgary building codes
You want a warranty

For many homeowners, paying for expertise is safer than risking leaks or damage.
