The Ultimate Guide to Starter Strip Shingles: What They Are and Why They Matter
When it comes to roofing, every component plays a critical role in ensuring the durability, performance, and aesthetics of your roof. One of the most essential yet often overlooked components is the starter strip shingles. These shingles might be small and thin, but they play a massive role in protecting your home and securing the overall roof system.
If you’re planning a new roof installation or replacement, understanding what starter strip shingles are, why you need them, how they’re installed, and how to choose the best ones can help you make informed decisions and avoid costly mistakes.
What Are Starter Strip Shingles?
Starter strip shingles are the first row of shingles installed along the eaves and rakes (edges) of your roof before the main shingles are applied. Unlike full shingles, starter strips are narrower and designed specifically to create a secure, sealed edge.
Their main purpose is to provide a solid base for the first course of regular shingles and to prevent wind-driven rain and uplift at the roof edges. They act as an underlayer that enhances water shedding and wind resistance.
Why Are Starter Strip Shingles Important?
While they might seem like a minor detail, starter strip shingles are crucial for several reasons:
1. Preventing Wind Uplift
Edges of the roof are the most vulnerable to wind damage. Starter strips secure the first row of shingles, ensuring they stay in place during strong winds, which helps prevent shingle blow-offs and roof damage.
2. Enhancing Water Protection
Starter strips provide an extra waterproof barrier along the eaves and rakes, helping direct water off the roof and preventing it from seeping under the shingles, which can cause leaks and rot.
3. Ensuring Proper Shingle Alignment
They create a straight, level edge for the main shingles to align against, improving the overall appearance and effectiveness of your roofing system.
4. Avoiding Shingle Damage
By providing a smooth base, starter strips reduce the risk of shingle edges lifting or curling at the roof edges, extending the life of your roof.
Types of Starter Strip Shingles
Starter strip shingles come in several types and styles, designed to match various roofing materials and aesthetics.
1. Pre-cut Starter Strips
These are manufactured strips designed specifically as starter courses. They are typically narrower than regular shingles and may come with adhesive strips for easy installation.
2. Cut-from-Standard Shingles
Many roofers cut standard 3-tab or architectural shingles to create starter strips. This option can be cost-effective but requires precision cutting for proper performance.
3. Roll Roofing Starter Strips
Some manufacturers produce starter strips on rolls, making installation faster and easier for large projects.
4. Specialty Starter Strips
For designer or architectural shingles, specialty starter strips with matching granules and shapes are available to maintain a consistent look.
How to Install Starter Strip Shingles: Step-by-Step Guide
Proper installation of starter strip shingles is critical. Incorrect installation can compromise the roof’s integrity.
Step 1: Preparation
- Clean the roof deck and install underlayment or ice-and-water shield along eaves and rakes.
- Measure and plan the starter strip placement.
Step 2: Starting at the Eaves
- Align the starter strip flush with the eave edge, overhanging slightly (usually about ¼ to ½ inch) to help direct water into gutters.
- Nail the starter strip securely using corrosion-resistant roofing nails, typically near the top edge to avoid nail exposure.
Step 3: Along the Rakes
- Continue installing starter strips along the rake edges, overlapping as recommended by the manufacturer.
- Ensure the starter strips form a continuous, sealed edge.
Step 4: Apply the First Course of Regular Shingles
- The first row of full shingles is installed over the starter strips, aligning the shingle tabs with the edges of the starter strips.
- This locks the shingles into place and improves wind resistance.
Common Mistakes When Installing Starter Strip Shingles
1. Skipping Starter Strips Altogether
Some installers skip starter strips to save time or cost, which can lead to edge blow-offs and leaks.
2. Improper Overhang
Not allowing the starter strip to overhang the roof edge can cause water to run behind gutters and damage fascia boards.
3. Nailing in the Wrong Place
Nails placed too low or too high on the starter strips can cause exposed nails, leading to leaks.
4. Using Damaged or Incorrect Starter Strips
Starter strips with missing granules or made from incompatible materials reduce effectiveness and aesthetic appeal.
Benefits of Using Starter Strip Shingles
Using starter strip shingles offers many long-term benefits for homeowners:
- Improved wind resistance, reducing repair costs after storms.
- Enhanced waterproofing, protecting your home from leaks.
- Longer lifespan of shingles by preventing edge damage.
- Cleaner, professional roof appearance.
- Compliance with manufacturer warranties, which often require starter strips.
Do All Roofing Manufacturers Require Starter Strip Shingles?
Most major roofing manufacturers recommend or require starter strip shingles as part of their installation guidelines to qualify for warranties. For example:
- Owens Corning insists on starter strips to ensure wind warranty coverage.
- GAF offers starter strips like their “WeatherBlocker” product to meet warranty standards.
- CertainTeed includes starter strips in their installation instructions for shingle warranty validity.
Always follow your roofing product manufacturer’s instructions.
How Much Do Starter Strip Shingles Cost?
Starter strip shingles are generally affordable compared to the overall roofing cost. Expect:
- Pre-cut starter strips: $15–$30 per bundle (covers about 100 linear feet).
- Cut-from-standard shingles: No extra material cost if using leftover shingles, but extra labor applies.
- Roll starter strips: Pricing varies, generally slightly more than pre-cut strips due to convenience.
Since starter strips are a small portion of the roofing project, the investment is worthwhile for the protection they provide.
When Should You Replace Starter Strip Shingles?
Starter strips should be replaced whenever you replace your roof shingles. If you’re doing a partial repair or patch, inspect the starter strips carefully:
- Look for cracking, missing granules, or curling edges.
- Replace damaged starter strips to prevent leaks and wind damage.
How Starter Strip Shingles Work With Other Roof Components
Starter strips complement other roofing components for a complete weather-tight system:
- Ice and Water Shield: Installed under starter strips in cold climates for additional leak protection.
- Drip Edge: Metal flashing along eaves/rakes to direct water away; starter strips help seal shingles to drip edge.
- Underlayment: Provides a base beneath starter strips and shingles to enhance waterproofing.
Tips for Choosing the Right Starter Strip Shingles
- Match starter strips to your main shingle type and color for a uniform look.
- Opt for pre-cut starter strips from reputable manufacturers for consistent quality.
- Consider starter strips with self-sealing adhesive for easier installation and stronger bonds.
- Confirm compatibility with your roofing system and local building codes.
DIY or Hire a Professional?
Installing starter strips might seem straightforward, but improper installation can cause major problems. Professional roofers:
- Have experience with correct placement, nailing, and flashing.
- Ensure compliance with manufacturer warranties.
- Use safety equipment and follow local code requirements.
Unless you’re experienced with roofing, hiring a professional is strongly recommended.
How Starter Strip Shingles Affect Your Roof Warranty
Many shingle manufacturers void warranties if starter strips aren’t used or improperly installed. This is because starter strips contribute significantly to wind resistance and water protection.
Always verify:
- That your roofing contractor uses the required starter strip shingles.
- Installation follows manufacturer guidelines and local codes.
- You receive warranty documentation outlining coverage details.
Environmental Impact and Starter Strip Shingles
Starter strips are typically made from asphalt-saturated fiberglass, similar to shingles, and can be recycled with other roofing materials. Choosing quality starter strips reduces the likelihood of premature roof damage and waste.
