Starter shingles form the first line of defense for any asphalt roofing system. These specialized strips, sometimes called starter courses, are installed along the eaves and rakes of your roof and provide essential protection against wind uplift and water infiltration that standard shingles alone cannot deliver. For Green Bay homeowners facing harsh Wisconsin winters and strong seasonal storms, properly installed starter courses can mean the difference between a leak-free home and major water damage.
Correct starter shingle placement creates a solid foundation for your entire roofing system by sealing the edges, preventing wind from lifting the first row of shingles, and directing water away from vulnerable roof components. Even experienced DIY enthusiasts sometimes miss key steps in this process that are essential for long-term roof performance.
This guide covers everything needed for proper roof starter strip application, from choosing materials and getting tools to mastering the installation techniques that weatherproof your roof edges. Whether you’re tackling a complete roof replacement or making repairs to an existing system, understanding these installation steps will make sure your roofing project begins with the structural integrity and weather resistance needed for lasting protection.
Tools and Materials Needed for Starter Shingle Installation
Before beginning your starter shingle installation project, gathering the right tools and materials is crucial for a successful outcome. For tools, you’ll need:
- Roofing hammer
- Pneumatic nail gun or manual hammer
- Galvanized roofing nails
- Chalk line for marking straight guidelines
- Utility knife with extra blades
- Tape measure
- Pry bar for removing old materials
- Safety equipment: a roof harness system, non-slip footwear, work gloves, and safety glasses
For materials, selecting the right starter shingles for Green Bay’s climate is essential. Look for high-wind rated starter strips designed to withstand Wisconsin’s strong weather patterns. GAF StarterMatch® or Owens Corning Starter Strip Plus shingles offer excellent wind resistance for our region. Calculate how many shingle bundles you need by measuring your roof’s eaves and rakes, then add 10% extra for waste. Most starter strips come in 10-foot sections, making it easy to determine how many bundles you should buy.
Don’t forget additional materials like roofing cement for extra wind protection at corners, an ice and water shield for extra protection from Green Bay’s freeze-thaw cycles, and underlayment. Using compatible products from the same manufacturer ensures your warranty remains intact. Having all materials on-site before beginning prevents mid-project delays and ensures your roof edges are completely protected from the challenging weather conditions we face in Northeastern Wisconsin.
Roof Preparation: Setting the Foundation for Successful Installation
Before placing a single starter shingle, proper roof preparation is essential to ensure your new roofing system performs as intended for years to come. Start by thoroughly inspecting your roof deck for signs of water damage, rotting wood, or structural issues. In Green Bay, moisture problems are common due to winter snow and spring thaws. Replace any damaged decking, as starter shingles require a solid foundation to effectively protect your home.
If you’re removing old shingles, use a tear-off shovel to strip the roof down to the deck, being careful not to damage the wood underneath. Clean the surface completely, removing all nails and debris. A ventilation assessment is crucial at this stage, as inadequate airflow can trap moisture and significantly reduce your roof’s lifespan.
Next, install drip edge along all eaves, followed by ice and water shield, which is particularly important in Green Bay to prevent ice dam damage. This membrane should extend at least 24 inches beyond your home’s exterior wall. Overlap sheets by at least 4 inches and secure them with cap nails. This underlayment creates the ideal base for your starter strips by providing an additional water barrier and even surface for the starter shingles to adhere to, maximizing their wind and water resistance capabilities.
Proper Positioning and Alignment Techniques
Mastering the precision of starter shingle placement will significantly impact your roof’s long-term performance and weather resistance. Begin by measuring and marking clear guidelines using a chalk line along all eaves. For proper water drainage in Green Bay’s heavy precipitation, ensure the starter strips overhang the eaves by 1/4 to 3/8 inch — never more or less, as improper overhang can lead to water infiltration or wind damage during our strong lakefront storms.
When positioning starter strips along the eaves, place them with the adhesive strip facing up and toward the roof’s edge. This orientation allows the self-sealing adhesive to bond with the first course of regular shingles, creating a wind-resistant seal. At the rake edges, install starter shingles after completing the eave installation, overlapping by at least 2 inches to eliminate vulnerable corner points where water could penetrate.
Common alignment mistakes to avoid include improper corner treatments where eave and rake starters meet. These intersections require special attention: cut the rake starter at a 45-degree angle to create a clean joint with the eave starter. When working around valleys, extend starter strips several inches into the valley line for complete water protection. Wisconsin’s freeze-thaw cycles make proper valley protection especially important for preventing damage caused by ice dams. Remember that straight, properly aligned starter courses set the foundation for every subsequent shingle row, so taking extra time with these measurements will create a more protective and visually appealing finished roof.
Nailing Patterns and Securing Methods for Maximum Wind Resistance
When installing starter shingles in windy Green Bay, the right nailing pattern makes a critical difference in roof performance. Each starter strip should receive four nails placed 1 to 3 inches above the roof edge. Space these nails evenly across the starter strip, approximately 3 to 4 inches apart, ensuring they penetrate both the starter shingle and roof deck by at least 3/4 inch for maximum holding power.
For eave installations, drive nails just above the factory-applied adhesive strip without puncturing it. This preserves the sealant’s wind-resistance properties while maintaining secure attachment. At rake edges, place nails about 1 inch in from the edge to prevent future water intrusion paths. Drive each nail straight and flush. Overdriven nails can tear through the material, while underdriven nails may catch on overlying shingles.
During installation, make sure to overlap consecutive starter strips. Butt each section tightly against the previous one without gaps but also without excessive overlapping. In high-wind zones along Green Bay’s lakefront areas, consider adding a quarter-sized dab of roofing cement beneath each starter strip corner for additional security. This reinforcement at transition points creates a continuous seal against both wind uplift and moisture intrusion, which is particularly important during freeze-thaw cycles when ice dams can form along roof edges and damage even properly installed roofing systems.
Transitioning from Starter Shingles to Main Roof Shingles
After installing your starter course, the transition to your first row of regular shingles requires careful attention to maintain curb appeal and improve weather protection. Begin by placing your first regular shingle directly on top of the starter course, aligning its bottom edge flush with the bottom edge of the starter shingle. This creates the crucial double-thickness at the roof edge that prevents water infiltration during Green Bay’s heavy rainfall and snow melt seasons.
For proper water shedding, maintain the recommended overhang established by your starter course. As you install the first row of regular shingles, offset the joints between these shingles from the joints in your starter course by at least 4 inches. This staggered pattern prevents water from finding a direct path through aligned seams — an important consideration in Wisconsin where freeze-thaw cycles can drive moisture upward under shingles.
Pay special attention to valleys and roof intersections during this transition phase. At valleys, trim shingles at a diagonal cut away from the valley centerline and embed the valley end of each shingle in roofing cement. Around dormers and other roof penetrations, weave shingles carefully with flashing to create water-tight barriers. Remember that many roof leaks in the Green Bay area develop at these transition points, so taking extra time with proper shingle placement here provides exponential returns in roof longevity and protection against our challenging northern weather conditions.
Final Inspection and Troubleshooting Common Installation Issues
Completing a thorough final inspection after starter shingle installation ensures your roof will provide reliable protection against Green Bay’s harsh weather conditions. Walk the entire perimeter of your roof, checking that all starter strips maintain a consistent 1/4 to 3/8 inch overhang at the eaves. Verify that there are no gaps between adjacent starter strips, as these can become entry points for wind-driven rain or snow. Examine all nail placement, confirming each nail is properly driven flush with the shingle surface without being overdriven or underdriven.
If you spot gaps between starter strips, apply a small amount of roofing cement beneath the area and press firmly to create a proper seal. For misplaced nails, remove them carefully with a flat pry bar, fill the hole with roofing cement, and re-nail in the correct position. Alignment issues can be more challenging to fix. If starter shingles were installed crooked, it may be necessary to remove and replace them before proceeding with regular shingles.
Watch for common mistakes like reversed starter strips, where the adhesive strip faces downward instead of upward. This significantly reduces wind resistance and requires complete removal and reinstallation. Also, check corner treatments where eave and rake starters meet to ensure water-tight seals. Taking time to identify and address these issues now prevents more serious problems later, especially during Wisconsin’s winter storms.
