Full job description

About Us

Advanced Roofing & Sheet Metal is a premium roofing and metal fabrication company based in Simcoe County, specializing in high-end custom homes, architectural roofing systems, and complex custom projects.

We are looking for a motivated, organized, hard-working assistant to work directly alongside the owner in a fast-paced and constantly changing environment.

This is an ideal opportunity for a college or university student looking for summer work and real-world experience in entrepreneurship, operations, manufacturing, sales, and business management.

What This Role Looks Like

No two days are the same.

One day may involve:

responding to emails and helping manage schedules
driving to meetings, suppliers, or jobsites
organizing projects and helping keep operations running smoothly
assisting with admin work and communication
helping in the shop with metal fabrication and manufacturing
assisting with content creation and marketing
solving problems and handling whatever the day throws at us

This is not a traditional office job.

You will work closely with the owner throughout the day and be involved in many areas of the business. The pace is fast, the expectations are high, and the hours can sometimes be long — but you will learn a tremendous amount about how a growing business operates.

The Ideal Candidate

You are:

highly organized
dependable and punctual
coachable
comfortable working hard
adaptable under pressure
confident communicating professionally
good with technology, email, and organization
willing to jump between office work and hands-on tasks

Bonus points if you:

are interested in entrepreneurship or business ownership
enjoy construction, manufacturing, automotive, or hands-on work
have experience driving trucks or trailers
can operate independently without constant supervision

Requirements

Valid Ontario G driver’s license
Clean and professional appearance
Strong communication skills
Comfortable working flexible hours when required
Must be able to lift and carry materials when assisting in the shop

What You’ll Gain

This role may not be the highest paying summer job, but it offers something many jobs don’t:

direct mentorship from a business owner
exposure to entrepreneurship and operations
real responsibility
hands-on experience
problem-solving skills
insight into how businesses actually grow

If you are ambitious, hardworking, and eager to learn, this position can become far more than just a summer job.

Compensation

$18–$22 per hour based on experience and capability
Overtime available
Opportunity for performance-based bonus
Valuable hands-on business experience

To Apply

Please send:

your resume
a short paragraph about yourself
why this role interests you
any experience you have working hard, solving problems, or taking initiative

We are looking for someone who is motivated, trustworthy, organized, and excited to learn.

Pay: From $20.00 per hour

Benefits:

Casual dress
On-site parking

Work Location: In person

Quick apply
