Starter Shingles: The One Piece That Can Void Your Warranty If Neglected

When most homeowners think about their roof, they picture the shingles on top. But one of the most important components of a properly installed roofing system is something you can’t even see once the job is finished: starter shingles.

At Custom Roofing Solutions, we don’t cut corners. Unfortunately, many storm-chasing or low-bid contractors do—and neglecting starter shingles is one of the most common and damaging shortcuts we encounter.

Why Starter Shingles Matter

Starter shingles are installed along the eaves and rakes—the lower and side edges of your roof. They serve several critical functions:

• Seal the roof edges to prevent wind uplift

• Provide a clean, secure base for the first row of shingles

• Help prevent water intrusion beneath the first course

• Ensure compliance with manufacturer installation requirements

In short, they’re not optional. They’re essential.

Minnesota Code Demands Proper Installation

According to the Minnesota Residential Code (R905.2.4.1), all asphalt shingles must be rated for a 115 mph ultimate design wind speed. To meet this rating, the shingles must be installed in full compliance with the manufacturer’s specifications—which always include starter shingles.

If your roof is missing this component, it may not meet code. More importantly, it may not stand up to the next storm.

Neglecting Starters Can Void Your Warranty

Every major shingle manufacturer—GAF, Owens Corning, CertainTeed—requires starter shingles for their system warranties to be valid. If a contractor neglects this step, your warranty could be voided entirely.

That means if something goes wrong with your shingles, you’re left footing the bill, even if the failure wasn’t your fault.

Why Contractors Cut This Corner

Some roofing contractors neglect starter shingles because:

• They want to reduce material costs

• They assume homeowners won’t notice

• They rely on insurance checks and don’t expect callbacks

But the consequences show up later—when wind lifts the shingles, water seeps in, or your insurance claim is denied due to an improper installation.
