How to Install Architectural Shingles
Steps for Installing Architectural Shingles
Does your roofing project involve installing architectural shingles? CedarTech Roofing, Inc. has helped countless property owners with their roofing projects, providing a wide array of outstanding services and valuable insights to make protecting their homes more manageable. We’ll gladly explain how to lay architectural shingles, where to nail the architectural shingles, and all other details of this task. Few homeowners are skilled roofers, and we strongly recommend leaving a roofing installation or reroofing project to seasoned professionals. However, we understand that many people are do-it-yourselfers or simply want to learn more about the topic. Below, we’ve provided helpful information about installing architectural shingles to keep you well-informed.

Start by Preparing for the Installation
This roofing project must begin with an inspection to verify your roof’s quality and ensure you have a solid foundation. Gather your roofing materials and tools before starting, including your starter shingles, which act as a secure foundation for the next set of shingles and prevent wind uplift. Next, you need to prepare the roof surface by removing dirt, debris, and old roofing material. Another crucial step is to repair damaged areas prior to laying your underlayment.
Step One: Install the Underlayment
Start by securing an underlayment across the entire roof deck. This crucial step establishes a vital secondary defense against water intrusion, safeguarding the structural integrity beneath your new architectural shingles. A properly installed underlayment is essential for protecting the wood against moisture damage and ice damming, as well as extending the lifespan of your roof. It also provides a smooth surface for shingle adhesion to ensure uniform application and a clean aesthetic. This foundational layer is integral to creating a resilient, weather-tight system built to withstand harsh conditions for decades.
Step Two: Start Installing at the Bottom
To properly install architectural asphalt shingles, start at the bottom edge of the roof. Align each shingle carefully with the roof’s edge, leaving the recommended overhang as outlined by the manufacturer. Beginning at the lowest point is crucial because it ensures water flows off the roof correctly, preventing leaks and water damage. This method also creates a sturdy base for the next rows, helping the shingles interlock seamlessly as you work upward.
Step Three: Apply Your Starter Shingle Strip
The initial starter strip application along the roof’s eaves is a foundational step, setting the stage for the entire shingle system. Ensure these strips are perfectly level and firmly fastened to provide a solid anchor for subsequent architectural shingles. Orient the sealant strip upward and towards the eave to create a watertight barrier. This careful placement seals the vulnerable edge and acts as a primary defense against wind uplift, significantly enhancing your roof’s resilience to severe weather.
Step Four: Layer Your Architectural Shingles
Begin laying your first full course of shingles directly over the starter strip, ensuring each one is flush with the lower edge. As you move upwards, each new row must overlap the one below it, covering the nail line and creating a watertight seal. This layering technique, often referred to as “staggering,” is critical. Offset the seams between shingles in adjacent rows according to the manufacturer’s guidelines. This staggered pattern enhances the roof’s visual appeal and is essential for preventing water infiltration and strengthening the overall structure against the elements.
Step Five: Use Proper Nailing Techniques
Proper nailing is critical for installing shingles. Below, we’ve described some helpful tips for nailing architectural shingles.
- Select Appropriate Nails – Always opt for roofing nails explicitly manufactured for architectural shingles. They must be long enough to pierce through the roofing material and deck without extending excessively to the underside.
- Maintain Consistent Spacing – Position your nails approximately one inch apart. This precise spacing is vital for securing the shingles firmly to the roof’s subsurface.
- Angle the Application – Drive each nail at a slight angle. This technique ensures a stronger, more reliable grip that anchors the shingles to the roof deck.
- Choose Your Tool Wisely – Employ either a nail gun for speed and efficiency or a hammer for careful placement. Both tools are suitable for fastening shingles, with the hammer offering greater manual control.
Step Six: Cut and Trim
As you progress toward the roof’s peak, you’ll find it necessary to fashion shingles around obstructions like vents, chimneys, and other roof protrusions. A utility knife is your best friend here, helping you achieve exact cuts for a tight seal. This careful approach maintains the roof’s overall soundness by guarding against potential water intrusion or harm.
Step Seven: Install Your Ridge Caps
After you finish laying the shingles on the main sections, your next step is to cover the roof’s peak with ridge caps. These caps add another layer of protection and give the roof a polished appearance while sealing off vulnerable seams to keep out water and other debris. CedarTech Roofing, Inc. will gladly explain why this finishing touch is crucial for ensuring your architectural shingles provide the best possible protection.
Step Eight: Inspect Your Roof and Clean Up
Once the shingle installation is complete, it’s time for a final inspection. Do a thorough walk-through of the entire roof, checking that you’ve securely fastened every shingle and aligned it correctly. After you’ve confirmed everything is in its proper place, clear away all debris, stray nails, and leftover materials from the area. This final cleanup leaves the site looking pristine and gives it a professional-grade finish that boosts your home’s curb appeal.
