10 Questions to Ask Before Hiring a Commercial Roofing Contractor in NZ

Hiring a commercial roofing contractor is not just a technical decision. It’s about risk, safety, and long-term cost.

For property managers and building owners, asking the right questions early can prevent delays, budget issues, and compliance problems.

At G A Pickford Roofing, we often work with clients across Auckland and Hamilton who want clear answers before starting a project.

Who this guide is for

This guide is most useful if you:

• Manage a commercial or industrial property
• Are planning a roof repair or replacement
• Need to compare contractors with confidence

For large corporate projects, many of these checks sit within formal procurement. But for most NZ buildings, these questions still apply.

1. Are you a Licensed Building Practitioner (LBP)?

This confirms the contractor meets NZ building standards.

Ask:

• Who holds the licence?
• Is it relevant to roofing work?

2. Are you a member of the Roofing Association of New Zealand (RANZ)?

Membership shows commitment to industry standards.

Ask:

• Are you a current member of RANZ?
• Do you follow their best practice guidelines?

This adds another layer of trust.

3. Do you have proven commercial experience?

Commercial roofing is very different from residential work.

Ask:

• Have you worked on warehouses, factories, or offices?
• Can you show similar scale projects?

G A Pickford Roofing focuses on commercial and industrial buildings, where planning and coordination are key.

4. Can you show recent local projects?

Local experience helps with weather, access, and compliance.

Ask:

• Do you have projects in Auckland or Hamilton?
• Can I see before and after photos?

5. What roofing systems do you specialise in?

Not all contractors handle all systems.

Ask:

• Do you install long-run metal roofing?
• Do you work with membrane systems?

The right system depends on your building, not just contractor preference.

6. What is your approach: repair or replacement?

A good contractor will be honest here.

Ask:

• Is repair a short-term fix?
• When does replacement make more sense?

Clear advice helps avoid repeat spend.

7. What safety standards and certifications do you have?

Safety is critical on commercial sites.

Ask:

• What health and safety systems do you follow?
• Are you SiteWise certified?

For example, G A Pickford Roofing is a SiteWise Gold member, which reflects strong health and safety practices.

8. What is included in your quote?

Clarity here avoids issues later.

Ask:

• Does it include materials, labour, and access equipment?
• Are there any exclusions?

9. What warranties do you provide?

This protects your investment.

Ask:

• Do you offer workmanship warranties?
• What do material warranties cover?

10. How will the project be managed?

This is often missed but very important.

Ask:

• Who is your main point of contact?
• How will the work be staged?
• How do you minimise disruption?

Good project management keeps things on track.
