When you think about your roof’s ability to withstand Norwell’s winter gales, Hull’s hurricane-force gusts, or Cohasset’s nor’easters, you probably picture sturdy shingles, solid decking, and tough underlayment. But there’s a small, often overlooked component that plays a critical role in keeping your shingles where they belong: starter shingles.
Without them, your roof’s wind resistance can drop dramatically and in coastal Massachusetts, that’s a risk you simply can’t afford.
What Are Starter Shingles?
Starter shingles are the first course of shingles installed at the eaves and sometimes the rakes (edges) of your roof. They:
Provide a solid base for the first row of visible shingles.
Seal the roof’s vulnerable edges against wind and water infiltration.
Help lock the bottom edge of the first row in place to resist wind uplift.
Why They’re So Important in Coastal Massachusetts
In Norwell, Hull, and Cohasset, roofs must withstand unique wind and weather challenges:
Wind-Driven Rain: Starter shingles seal gaps where water could be pushed under your shingles.
Wind Uplift: Strong gusts can catch the bottom edge of shingles; starter shingles create a glued seal to prevent peeling.
Ice Dams: In Norwell winters, starter shingles combined with ice & water shield help block backed-up meltwater.
What Happens Without Starter Shingles?
Skipping starter shingles or using cut-up 3-tab shingles instead can lead to:
Shingles peeling back during storms.
Water infiltration at roof edges.
Shortened roof lifespan and voided warranties.
Starter Shingle Features for Coastal Areas
Adhesive Strip – High-tack adhesive bonds the starter shingle to the first row for maximum wind resistance.
Proper Overhang – Extends slightly past the fascia to direct water into the gutters.
Coastal-Grade Materials – Choose asphalt shingles rated for 130+ mph winds for Hull’s exposed neighborhoods.
Best Installation Practices in Norwell, Hull, and Cohasset
Full-Length Starter Shingles: Avoid piecing together scraps — full-length pieces prevent gaps.
Nailing Pattern: Follow manufacturer’s high-wind nailing specs — usually six nails per shingle.
Sealant Activation: Install in temperatures that allow the adhesive to activate, or hand-seal in colder months.
Town-Specific Considerations
Norwell: Snow load and ice dams make sealing at the eaves especially important.
Hull: High wind exposure demands upgraded starter shingles with reinforced adhesive.
Cohasset: Historical homes may have complex rake edges that require custom starter shingle trimming.
Cost vs. Benefit
Starter shingles cost only a small fraction of the overall roof price but add years of performance and protection. For example:
Adding premium starter shingles may add $200–$500 to a roof job.
Avoiding edge blow-offs after one storm can save $2,000+ in repairs.
Signs of Starter Shingle Failure
Lifting shingles along eaves or rakes after storms.
Water stains on fascia boards.
Gaps visible between the bottom row of shingles and the decking.
Final Word for South Shore Homeowners
In coastal towns like Norwell, Hull, and Cohasset, starter shingles aren’t optional — they’re essential. They may be invisible from the curb, but they’re one of the most important defenses against wind damage. If you’re replacing your roof, ask your contractor exactly what starter shingles they use and ensure they meet high-wind and coastal performance standards.
