When homeowners schedule a roof replacement, it’s the perfect time to assess and update any skylights on the home. But many roofing professionals still face the question: should skylights be replaced during re-roofing? At North Star Skylights, we partner with Minnesota roofers to ensure skylight upgrades are done right on time, on budget, and with no callbacks. Here’s what you need to know.
Why Skylight Replacement Makes Sense During Roof Work
Every skylight has a finite lifespan. Even high-quality VELUX skylights are rated for around 20-30 years, depending on exposure and installation quality. Over time, seals deteriorate, flashing systems become outdated, and the glass itself may lose clarity or energy efficiency. If a skylight is nearing the end of its service life, replacing the roof while leaving the original skylight in place invites trouble.
Here’s why we recommend replacement during re-roofing:
- Avoids double labor: Installing a new skylight after a roof has been completed requires cutting into the fresh roofing materials. This not only doubles the labor and cost, but also increases the risk of damaging the roof deck or voiding material warranties. Replacing the skylight during the roofing phase streamlines the process.
- Reduces future leaks: Even a brand-new roof cannot protect against leaks originating from an old skylight. Aging seals, worn gaskets, and brittle glazing materials can all lead to water intrusion. By addressing skylights during re-roofing, you mitigate this risk entirely.
- Preserves warranties: Both roofing and skylight manufacturers have strict installation guidelines. If a skylight is not installed using up-to-date flashing kits or doesn’t meet the latest best practices, warranty coverage can be compromised. Coordinated replacement ensures all components are covered properly.
Replacing skylights while the roof is open is efficient, cost-effective, and ensures a better long-term outcome for both the Minnesota contractor and the homeowner.
Coordinated Install Keeps Your Crew Moving
One of the biggest concerns roofers have is managing trade overlap and jobsite timing. Delays caused by waiting on other trades can slow down production, especially during peak season. That’s where North Star Skylights makes a difference.
We coordinate directly with your project manager or foreman to ensure skylight replacement doesn’t disrupt your flow. Our process is streamlined and designed with your schedule in mind:
- We review skylight age, condition, and replacement suitability in advance, either through job photos or a quick site visit.
- Our installers are scheduled to arrive during your active roofing phase, typically the same day shingles are being removed and decking is exposed.
- We handle removal of old skylights and installation of new units, including flashing systems compatible with the new roofing material.
- If needed, we return after roofing is complete to finish interior trim or drywall work, minimizing on-site overlap.
Because we specialize exclusively in VELUX skylights, we know how to complete replacements efficiently and without the need for supervision. Your crew stays focused on roofing, while we handle the daylighting.
When to Recommend Skylight Replacement
Roofers are not expected to be skylight experts, but a few simple signs can help you know when to recommend an evaluation by North Star Skylights. Keeping an eye out for these indicators can prevent future headaches for both you and the homeowner:
- Glass is foggy, cracked, or yellowed: Discolored or cloudy glass usually indicates seal failure. It also affects daylight clarity and can signal the end of a skylight’s useful life.
- Interior signs of leaks (stains, peeling paint): Staining or bubbling paint near the skylight trim is a red flag. Even if it hasn’t been active recently, signs of moisture damage suggest the unit has been leaking.
- Fixed-glass units in high-moisture areas: Bathrooms or kitchens with fixed skylights often experience condensation buildup. Replacing with venting models can dramatically improve airflow and prevent mildew.
- Homeowners ask about ventilation or energy efficiency: If a customer expresses interest in improving comfort, natural ventilation, or lowering energy bills, it’s a good time to bring in a skylight expert.
Skylights over 15 years old are typically due for replacement. Offering that insight during your roofing consultation positions you as a more knowledgeable and proactive contractor.
Better Outcomes for Homeowners—and Your Reputation
Teaming up with North Star Skylights adds professionalism and confidence to your roofing project. When customers see you working alongside certified skylight experts, they trust that you’re covering all the bases and not just rushing through a job. That reflects well on your reputation and helps prevent costly callbacks down the line.
Some key homeowner benefits include:
- No callbacks: A professionally installed skylight using the proper flashing system prevents future water issues. That saves everyone time and money.
- Energy efficiency: Modern VELUX skylights feature double-pane Low-E3 glass, thermal breaks, and integrated shades that help regulate indoor temperatures and reduce utility costs.
- Smart upgrades: Solar-powered skylights and blinds can be operated by remote or smart home app. Plus, they qualify for a 30% federal tax credit, which offsets the cost of installation.
By proactively offering skylight replacement, you not only improve project quality but also add more value to your bid. Homeowners want options that enhance comfort, performance, and resale value. Skylights check all three boxes.
