Starter shingles sit at the eaves of an asphalt shingle roof and are designed to provide a secure, watertight first row. This article explores what starter shingles are, their benefits, whether they are strictly necessary, and situations where homeowners might opt to skip them. It also covers installation tips, cost considerations, and practical guidance for choosing the right approach for a durable, weather-resistant roof.
What Are Starter Shingles
Starter shingles are a specialized first course installed along the eaves before the main shingles. They typically come in a peel-and-stick or tabbed design and include an adhesive sealant that helps bond subsequent shingles. The purpose is to create a weather-tight edge, protect against wind uplift, and reduce the risk of leaks at the roof’s perimeter. Some versions are sold as a dedicated starter strip, while others are shaped to resemble a small strip of shingles.
Benefits Of Starter Shingles
Enhanced wind resistance at the rakes and eaves is a primary advantage. The adhesive bond along the starter row aids in preventing shingles from lifting in high winds, which is especially important in exposed areas or regions with strong gusts.
Improved water management by creating a clean, straight edge for the first row helps ensure proper shingle alignment and reduces potential leakage paths that can develop beneath improper edges.
Cleaner installation with a defined starting line reduces the risk of misalignment for the remainder of the roof. This can translate to better overall performance and a more visually appealing roof edge.
Compatibility with underlayment Starter shingles work well with typical asphalt underlayment and roofing felt, providing an extra layer of protection as the roof ages.
Are Starter Shingles Necessary
The necessity of starter shingles depends on factors such as local wind uplift requirements, roof design, and manufacturer recommendations. In many modern installations, starter shingles are advised or required by shingle manufacturers to preserve warranty coverage and optimize performance. DIY guides and professional contractors often emphasize that the starter row helps seal the roof perimeter and prevents common failure points at eaves and overhangs.
However, some builders install a modified approach using a traditional starter course formed from cut pieces of shingles or a self-sealing strip integrated into the first row. In certain minor or low-wind environments, some roofers may omit a dedicated starter row if they implement stringent overhang alignment, high-quality flashing, and a robust ice-and-water shield at the eaves.
In short, starter shingles are highly recommended for most asphalt shingle roofs, especially in regions with high wind speeds or where building codes and warranty terms require them. Skipping starter shingles can save upfront costs but may increase long-term risk and compromise warranty coverage.
Situations When You Can Skip Starter Shingles
There are limited scenarios where omitting a dedicated starter row might be acceptable. These include:
- Diligent use of compatible high-quality flashing along eaves and rakes that provides a continuous seal.
- Installation with a robust ice-and-water shield over the entire eave line, offering moisture protection without a separate starter strip.
- Regional building codes or manufacturer specifications that do not mandate a dedicated starter row for certain shingle lines.
- Professional assessments that determine wind exposure is moderate and a standard edge alignment can be achieved without a dedicated starter.
Even when skipping, ensure that other protective components—such as proper attic ventilation, attic insulation, and a continuous weather barrier—are properly installed to minimize risk.
Installation Tips And Best Practices
- Follow manufacturer instructions. Warranty terms often hinge on using the specified starter method. Use the starter shingles or an equivalent starter strip recommended by the shingle maker.
- Prepare a straight edge. Ensure the eaves are clean and level. A straight line is essential for a uniform starter row and subsequent courses.
- Consider peel-and-stick options. Peel-and-stick starters provide a strong seal at the eaves and reduce the need for nailing in vulnerable locations.
- Use proper nailing patterns. Adhere to recommended nail placements and counts to maintain wind resistance and warranty coverage.
- Ensure proper flashing integration. Install lead-edge flashing and door/window penetrations correctly to prevent leaks where the starter row meets other components.
- Inspect for gaps. After installation, check for gaps or misaligned edges that could allow water intrusion or wind uplift.
Cost Considerations
Starter shingles add modest upfront cost but can influence long-term durability and warranty. Typical cost factors include:
- Material type and brand; peel-and-stick starters often cost more than standard asphalt.
- Labor efficiency; a properly installed starter row can speed up subsequent roofing work and reduce errors.
- Warranty implications; manufacturers may require starter shingles to maintain coverage.
- Regional price variation; wind-prone areas may see higher installation costs due to stricter requirements.
When budgeting, compare the price of a dedicated starter strip against the potential costs of repairs or replacements due to wind uplift or leaks if a starter row is omitted. In many cases, the added protection justifies the investment.
Aesthetic And Color Considerations
Starter shingles can affect the visible edge of the roof profile, especially if a non-matching color option is used. To preserve a cohesive appearance, choose a starter material and color that blends with the main shingles or opt for a dedicated starter that matches the brand’s color family. A well-chosen starter row contributes to a cleaner, more professional finish while maintaining curb appeal.
Maintenance And Longevity
Regular roof inspections should focus on the eaves, rakes, and starter edge. Look for lifted tabs, cracked sealant, or gaps around the starter row after heavy weather. Proper maintenance, combined with a correct installation, can extend roof life and protect against leaks. Keep gutters clear so water can shed properly from the eaves, reducing pressure on the starter area.
Practical Guidance For Homeowners
To determine whether starter shingles are right for a project, consult the chosen shingle manufacturer’s guidelines and local building codes. Engage a licensed roofing contractor who can assess wind exposure, roof pitch, and overall roof design. For most U.S. homes, using a dedicated starter strip is a prudent choice that aligns with best practices for durability and warranty protection.
Summary
Starter shingles provide a defensible edge against wind uplift and water intrusion, support precise alignment, and help preserve warranty coverage. While there are niche circumstances where a skip may be contemplated, for most asphalt shingle roofs, using a dedicated starter row is a recommended standard. Weigh the upfront cost against long-term protection, and follow manufacturer directions to maximize performance and longevity.
