Choosing the Right Contractor: Questions to Ask Before You Cut a Hole in Your Roof

Installing a skylight can transform a room with natural light, improve ventilation, and even increase the appeal of your home. But before you choose a skylight model or schedule an installation, there is one critical decision to make: selecting the right contractor.

A skylight is only as good as the installation behind it. Even the highest-quality skylight can develop leaks, drafts, or performance issues if it is not installed correctly. That's why homeowners should spend as much time evaluating their installer as they do selecting their skylight.

If you're considering a new skylight, replacement skylight, or upgrading to a modern Velux skylight, here are the questions every homeowner should ask before anyone cuts a hole in their roof.

Why Does the Contractor Matter So Much?

Many roofing contractors can install a skylight. However, not every roofer specializes in skylight installations.

A skylight installation involves more than simply cutting an opening and dropping in a window. Proper sizing, roof integration, flashing systems, underlayment, ventilation considerations, and manufacturer specifications all play a role in long-term performance.

The difference between a successful installation and years of headaches often comes down to experience and attention to detail.

Question #1: Are You Experienced Installing Velux Skylights?

If you're investing in a Velux skylight, your contractor should be familiar with Velux products and installation requirements.

Ask questions such as:

• How many Velux skylights have you installed?
• Have you worked with both fixed and venting Velux models?
• Are you familiar with Velux flashing kits?
• Can you provide examples of recent installations?

Velux designs its skylights as complete systems. The skylight, underlayment, and flashing components are engineered to work together. A contractor familiar with these systems is more likely to follow installation best practices and maximize performance.

Question #2: Will My Manufacturer Warranty Remain Valid?

One of the biggest mistakes homeowners make is assuming all installations automatically qualify for manufacturer warranty coverage.

Ask your contractor:

• Will the installation follow Velux guidelines?
• Are approved flashing kits being used?
• Will all required components be installed?
• How is warranty documentation handled?

Improper installation can create issues that may affect warranty coverage. A qualified installer should be able to clearly explain the process and answer questions about manufacturer requirements.

Question #3: What Flashing System Will You Use?

Many skylight leaks are not caused by the skylight itself. They are caused by improper flashing.

Flashing is the system that directs water away from the skylight opening and safely onto the roof surface. It is one of the most important components of a successful installation.

Ask:

• What flashing system will be used?
• Is it designed specifically for my roof type?
• Is it manufacturer-approved?
• How will the flashing integrate with existing roofing materials?

A contractor who cannot clearly explain their flashing approach may not be the right fit for the project.

Question #4: Do I Need a Permit?

Permit requirements vary by city, county, and municipality.

Before beginning work, ask:

• Is a permit required for this installation?
• Who obtains the permit?
• Will inspections be required?

A reputable contractor should understand local requirements and guide homeowners through the process when permits are necessary.

Question #5: What Type of Skylight Is Best for My Home?

Not every skylight is the same.

Your contractor should discuss options such as:

Fixed Skylights

Designed to provide natural light without ventilation.

Venting Skylights

Allow fresh air into the home and can help release trapped heat.

Solar-Powered Skylights

Offer convenient operation and energy-efficient ventilation.

Replacement Skylights

Designed to upgrade aging or damaged skylights while improving performance.

A knowledgeable installer should explain the advantages and limitations of each option based on your home's layout, roof design, and goals.

Question #6: How Will You Protect My Roof During Installation?

A skylight project involves working directly with your roofing system.

Ask your contractor:

• How will roofing materials be protected?
• What happens if hidden damage is discovered?
• How is weather exposure managed during installation?
• What cleanup procedures are followed?

Professional contractors should have clear processes in place to protect both the roof and the interior of your home.

Question #7: Can You Provide References or Photos?

Experienced contractors should be proud of their work.

Ask for:

• Recent project photos
• Customer references
• Online reviews
• Examples of similar installations

Seeing completed projects can help homeowners better understand installation quality and craftsmanship.

What Are the Red Flags When Hiring a Skylight Contractor?

Homeowners should be cautious if a contractor:

• Cannot explain flashing systems
• Avoids questions about permits
• Has limited skylight-specific experience
• Cannot provide references
• Offers unusually low pricing compared to competitors
• Recommends shortcuts instead of manufacturer-approved methods

Choosing a contractor based solely on price often leads to expensive repairs later.
