Brand Loyalty is the repeated choice of a brand over others by a customer, built on trust, satisfaction, and positive experiences. Monitoring this metric helps businesses understand the depth of their customer relationships and their commitment level.

Why is it Important

Steady Revenue: Loyal customers mean repeat business and a reliable income stream.

Referral Growth: Happy customers naturally recommend your brand, aiding in cost-effective customer acquisition.

Market Stability: A loyal customer base helps withstand competitive market shifts.

Cost Efficiency: It's cheaper to retain existing customers than acquire new ones, reducing marketing expenses.

Valuable Feedback: Loyal customers often provide critical insights for product or service improvements.

Introduction

“We could not find a nail or shingle after cleanup. We thank them for a great job and highly recommend them.” — a homeowner served by Mast Roofing & Construction. With the Residential Solar Tax Credit (Section 25D), offering a 30% credit, ending after December 31, 2025, many homeowners and roofing contractors are racing against the clock.

If you’re thinking of adding solar panels to your roof—or you’re a roofing contractor coordinating with solar installers—this deadline could mean thousands in savings or losses. Here’s what you need to know, what to do now, and how Mast Roofing & Construction can help.

What Is Changing & Why It Matters

Under the One Big Beautiful Bill Act, signed July 4, 2025, the federal residential solar tax credit is terminated as of December 31, 2025. There is no gradual phase-out.

To claim the full 30% tax credit, your solar system must be fully installed and commissioned by that deadline. If not, the credit is gone.

For commercial solar projects, deadlines are different: construction must begin by July 4, 2026, or the system must be placed in service by December 31, 2027.

What This Means for Roofing & Solar Projects

Roofing plays a critical role in solar installations. Here’s what this situation means in practice:

  • Permits, inspections, and interconnection often cause delays. A roofing delay (repairs, structural reinforcement, or re-roofing) can delay everything.
  • If the roof is not in good condition, repairs or full replacements may be necessary before solar mounting—this adds time and cost.
  • Demand for solar mounting hardware, specialized flashing (for roof penetrations), and roofing materials will surge. Long lead times are likely.

Steps Homeowners Should Take Now

Have your roof inspected — check for damage, age, or structural issues so that you know whether repair or replacement is needed before solar.

Get detailed bids and contracts early — choose contractors who guarantee that the work will be completed and commissioned before December 31, 2025.

Check local permitting & inspection timelines — some municipalities are slow; understand their schedules so you can plan backward from the deadline.

Consider battery storage — if you’re going for battery storage along with solar, make sure it qualifies and can be installed in time.

Here’s how Mast Roofing & Construction is uniquely positioned to help homeowners beat this deadline and get quality roof + solar jobs done:

  • Experienced with storm damage and emergency work — meaning they’re used to tight timelines and urgent repairs[2].
  • Customer-focused communication and project peace of mind — their reviews show clients feel supported and well informed[2].

Key Timelines & Risks

Deadline Requirement:

  • December 31, 2025: Residential solar systems must be fully installed and commissioned to qualify for the 30% federal tax credit.
  • July 4, 2026: For commercial solar: construction must begin by this date for full benefits.
  • December 31, 2027: Commercial systems must be placed in service by this date if they meet the earlier construction-start deadline.

Risks you need to watch for:

Weather delays (especially late-season storms or winter) that slow down roofing or installation.

Material or supply chain delays (solar panels, metal flashings, mounts, etc.).

Permits and inspections taking longer than expected.

Discovering roof issues (structural damage, rot, leaks) late in the process.

Why Acting Before 2026 Is Important for Homeowners & Roofers

For homeowners: After December 31, 2025, you lose the chance for the 30% federal savings. Good roof condition, contract timing, and commission date all matter.
