Shingle Starter Course: Foundation For Proper Installation
A well-installed roof starts with more than just shingles—it begins with the right foundation. One of the most important yet often overlooked elements in residential roofing is the shingle starter course. Whether you're building a new home in Villa Ridge or replacing an aging roof, getting the starter course right can mean the difference between a watertight seal and long-term issues.
At Utz Roofing, we understand the nuances of correct shingle installation. This guide will walk you through everything homeowners need to know about the shingle starter course—what it is, why it matters, and how it protects your investment.
What Is A Shingle Starter Course?
The shingle starter course is the first row of shingles installed along the eaves and sometimes the rakes (the sloped edges) of your roof. Unlike the rest of the shingles, the starter course is designed specifically to provide extra waterproofing and structural integrity at the roof’s most vulnerable points.
Starter shingles have a special adhesive strip that helps seal the edges and hold the first course of field shingles in place. They also eliminate gaps created by standard shingle cutouts and ensure correct alignment from the very beginning.
Why The Shingle Starter Course Matters
The shingle starter course plays a crucial role in roof performance. Without it, your roof is left vulnerable to several problems, including:
Wind uplift at the edges
Water penetration under the first row
Misaligned shingles from the start
Reduced manufacturer warranty protection
In Villa Ridge, where wind and rain can hit hard, especially in transitional seasons, a properly installed shingle starter course is critical for a secure and lasting roof.
Common Mistakes With Starter Courses
Even some experienced roofers make errors when installing the shingle starter course. Here are a few common issues we encounter during repairs and replacements:
Using Field Shingles as Starters
Some contractors cut regular shingles and install them upside down as a starter course. While this might appear to save time, these do not have the correct sealant strip placement, which compromises edge adhesion.
Improper Overhang
The starter course should slightly overhang the drip edge by about ¼ to ¾ inch to channel water into the gutters. Too little or too much overhang can cause problems with water management or appearance.
No Adhesive Contact
If the adhesive strip on the starter shingle doesn’t properly bond with the first course of shingles above, the roof’s wind resistance is weakened, especially during storms.
Reversed Placement
Installing the shingle starter course with the adhesive strip on the wrong side or upside down can completely defeat its purpose.
How Utz Roofing Installs Starter Shingles The Right Way
At Utz Roofing, our process for installing the shingle starter course follows best practices recommended by manufacturers like GAF, Owens Corning, and CertainTeed. Here’s how we do it:
Drip Edge Placement: First, we install a drip edge along the eaves to direct water runoff away from the fascia and into the gutters.
Starter Strip Alignment: We use manufacturer-designed starter strips and align them perfectly along the edge, ensuring they slightly overhang the drip edge.
Correct Adhesive Orientation: The adhesive strip is always placed facing up and toward the edge, ready to seal the first course of shingles.
Consistent Nail Placement: Nails are placed according to the product's specifications to ensure holding power without over-penetration.
Double Starter for Rakes: On homes where wind uplift is a major concern—especially in more open areas of Villa Ridge—we often apply starter strips along the rakes as well.
By following this system, we help homeowners maximize their roof’s lifespan and maintain eligibility for full manufacturer warranties.
Starter Course And Wind Resistance
One of the biggest reasons we emphasize the shingle starter course is its role in wind protection. Without a properly adhered starter strip, shingles along the edges of your roof are prone to lifting in high winds. This leads to water intrusion and progressive shingle loss.
For homeowners in Missouri, where wind gusts often exceed 50 mph, a secure starter course is non-negotiable.
Shingle Starter Course And Ice Dams
In colder months, Villa Ridge residents often deal with ice dams. These occur when melting snow refreezes at the eaves, causing water to back up under shingles. A correctly installed shingle starter course, paired with proper underlayment and ice shield membranes, helps minimize the risk of leaks from ice dams.
How Starter Courses Fit Into A Full Roofing System
The shingle starter course may be the first component installed, but it’s part of a larger system that includes:
Ice and water shields
Synthetic underlayment
Drip edges
Ventilation systems
Properly spaced fasteners
Ridge caps and flashing
All of these work together to form a roof that resists wind, water, and weather extremes. Skipping or skimping on the starter course weakens the whole system.
DIY vs Professional Starter Course Installation
While handy homeowners may be tempted to try roofing themselves, the shingle starter course is a step where precision and product knowledge matter. A professional installer like Utz Roofing ensures:
Code compliance
Warranty protection
Proper adhesion and alignment
Seamless integration with other roof components
Mistakes with starter shingles are often invisible until it's too late—when a leak or blow-off occurs.
How To Tell If Your Starter Course Is Failing
If your roof was installed years ago or by someone else, here are signs that your shingle starter course might not be doing its job:
Shingles at the edges lifting or curling
Water stains near eaves or ceilings
Missing shingles after a moderate storm
Sagging areas near roof edges
If you see any of these, call Utz Roofing for a roof inspection. Catching a starter course issue early can prevent thousands in repair costs.
Starter Courses For Different Shingle Styles
Not all starter strips are created equal. We tailor your shingle starter course to match the type of roofing shingles being installed:
Three-tab shingles: Basic straight-line starter courses
Architectural shingles: Require wider starter strips for proper alignment
Designer or luxury shingles: Often require specially made starter components for compatibility
Our crews ensure that every installation respects the unique requirements of your shingle selection.
Cost Of A Shingle Starter Course
The shingle starter course is one of the least expensive components in your roofing system, but one of the most essential. Installed correctly, it adds just a small fraction to total project cost, but it prevents major losses down the road.
At Utz Roofing, we include starter strips in every full roof replacement, and we only use brand-specific, high-quality materials.

Real-Life Case Study: Storm Repair in Villa Ridge
In 2023, a family in Villa Ridge called us after noticing missing shingles and ceiling stains. A windstorm had damaged their roof’s edge. Upon inspection, we discovered their original contractor had skipped the shingle starter course entirely.
We replaced the damaged decking, installed proper ice and water shields, and applied a full starter strip before laying new shingles. The homeowners now have a roof they can trust—with a warranty to match.
Frequently Asked Questions
Can I use leftover shingles as a starter course?
No. Regular shingles don’t have the necessary adhesive strip placement for edge sealing. Starter-specific shingles are engineered for this purpose.
Do all roof edges need a starter course?
At minimum, the eaves require a starter course. Installing them along the rakes is also highly recommended, especially in wind-prone areas.
How long do starter shingles last?
Starter shingles last as long as your roof—usually 20 to 30 years—provided they are installed correctly and not exposed to unusual stress.
