Preparing for Shingle Installation
Assessing the Roof Deck
Before any shingles can be laid, it’s very important to be sure that the roof deck is in optimal condition. This step is often overlooked but is fundamental to the longevity and performance of your new roof. A thorough inspection of the roof deck allows us to identify any potential issues that could compromise the integrity of the new shingles.
During this assessment, we look for signs of rot, water damage, or structural weaknesses. Any damaged or deteriorated sections of the deck must be repaired or replaced before proceeding. Additionally, we make sure that the deck is clean, dry, and free from any protruding nails or debris that could interfere with the installation process.
It’s worth noting that a solid, well-maintained roof deck provides a stable foundation for your new shingles and also contributes to the overall energy efficiency of your home. A properly prepared deck helps prevent air leaks and moisture infiltration, which can lead to increased energy costs and potential damage to your home’s interior.
Installing the Underlayment
Once the roof deck is deemed suitable, the next critical step is installing the underlayment. This layer serves as a secondary barrier against water infiltration and is inevitable for protecting your roof deck from moisture.
The type of underlayment used can vary depending on climate conditions and local building codes, but typically includes materials like synthetic underlayment or traditional felt paper. The underlayment is rolled out horizontally across the roof deck, starting at the bottom edge and working upwards.
Each row overlaps the one below it to ensure complete coverage and prevent water from seeping between layers. Special attention is paid to :
- Areas around chimneys;
- Vents;
- And valleys where water is more likely to accumulate.
In regions prone to ice dams or heavy rainfall, we often install an additional waterproof membrane along the eaves, valleys, and other vulnerable areas. This extra layer of protection (known as an ice and water shield) adheres directly to the roof deck and provides superior water resistance in critical areas.

The Shingle Installation Process
Starting with the Starter Strip
The installation of the actual shingles begins with the starter strip, a vital component that’s often overlooked in DIY installations. The starter strip is a row of shingles or a specialized starter material that’s installed along the eaves of the roof.
Its primary purpose is to provide a straight edge for the first row of shingles and to fill in the spaces between the shingle tabs in the first course. Proper installation of the starter strip is important for several reasons:
- It ensures that the first row of shingles is properly aligned, setting the stage for straight and even subsequent rows;
- It provides additional protection against wind uplift at the roof’s edge, where wind forces are typically strongest;
- It helps prevent water from seeping under the first row of shingles, protecting the vulnerable edge of the roof deck.
The starter strip is typically installed with the adhesive strip facing up and hanging slightly over the edge of the roof. This overhang, usually about 1/4 to 3/4 inch, allows water to drip off the roof instead of running back underneath the shingles.
Laying the First Course
With the starter strip in place, the specialists can begin laying the first course of shingles. This initial row sets the foundation for the entire roof, so precision is paramount. The first course is typically laid directly over the starter strip, with the shingles aligned flush with the edge of the starter strip.
You should know that one common mistake in DIY installations is failing to properly offset the first course from the starter strip. This offset is necessary for creating a water-tight seal and preventing a straight line where water could potentially penetrate. We ensure that the joints between shingles in the first course don’t align with the joints in the starter strip.
As we lay each shingle, we pay careful attention to the manufacturer’s guidelines for nail placement. Typically, four to six nails are used per shingle, depending on factors like the roof’s pitch and local wind conditions. Proper nailing is important for the shingles’ wind resistance and overall longevity.
Continuing with Subsequent Courses
Once the first course is securely in place, we proceed with the subsequent courses, working our way up the roof. Each new row of shingles overlaps the one below it, typically by about half the shingle’s length. This overlap is Crucial for creating a water-resistant barrier and achieving the classic layered look of a shingled roof.
One of the key aspects of professional shingle installation is maintaining proper alignment and spacing between courses. We use chalk lines to ensure straight rows and consistent exposure (the visible portion of each shingle). This not only enhances the roof’s appearance but also ensures optimal performance and longevity.
Another critical factor in this stage is the staggering of shingle joints. We never allow the joints between shingles to line up in adjacent courses, as this could create a path for water to penetrate the roof. Instead, we use a staggered pattern, typically offsetting each course by 4 to 6 inches from the one below it.
Handling Special Areas and Features
Valley Installations
Roof valleys, where two roof planes intersect, require special attention during shingle installation. These areas are particularly vulnerable to water infiltration and must be carefully waterproofed. There are several methods for shingling valleys, including the “closed valley” and “open valley” techniques.
In a closed valley installation, shingles from both roof planes are woven together or layered over each other. This method creates a seamless look but requires precise cutting and positioning of shingles to ensure proper water flow.
An open valley, on the other hand, uses metal flashing exposed in the center of the valley, with shingles cut back on each side. This method is often preferred in areas with heavy rainfall or snow, as it provides a clear path for water to flow down the roof.
Regardless of the method chosen, proper underlayment and flashing installation in the valley is also essential. We typically use a heavy-duty underlayment or ice and water shield in these areas for added protection.
Installing Around Roof Penetrations
Roof penetrations such as skylights, vents, and chimneys present unique challenges in shingle installation. These areas require careful flashing and sealing to prevent leaks. The process typically involves:
- Installing base flashing around the penetration.
- Carefully cutting and fitting shingles around the obstacle.
- Installing step flashing as each course of shingles is laid.
- Applying a final layer of counter flashing for added protection.
Proper installation around these features is not neglectable for preventing leaks and ensuring the long-term integrity of your roof. It’s often in these areas where DIY installations fall short, leading to costly repairs down the line.
Finishing Touches
Ridge Cap Installation
The final step in shingle installation is the application of ridge caps. These specialized shingles are designed to cover the peak of the roof where two planes meet. Ridge caps not only provide a finished look to the roof but also play a capital role in protecting this vulnerable area from water infiltration and wind damage.
Installing ridge caps requires careful attention to detail. Each cap must be properly overlapped and secured to ensure a watertight seal. In areas prone to high winds, we may use additional adhesive or specialized high-wind ridge caps for added security.
Final Inspection and Cleanup
Once all shingles and ridge caps are in place, we perform a thorough inspection of the entire roof. This final check allows us to identify and address any potential issues, such as misaligned shingles or improper nail placement.
We also take great care in cleaning up the job site and removing any debris or stray nails that could pose a hazard. A clean job site reflects our commitment to professionalism but also ensures the safety of you and your family.
Maintenance and Care for Your New Roof
Regular Inspections
To maximize the lifespan of your newly installed shingles, regular inspections should become a priority. We recommend having your roof professionally inspected at least once a year, ideally before the start of the harshest weather season in your area. During these inspections, a professional roofer will look for signs of damage or wear, such as:
- Cracked, curled, or missing shingles;
- Exposed nails or popped nail heads;
- Signs of water damage or leaks in the attic;
- Damaged or missing flashing around roof penetrations.
Catching and addressing minor issues early can prevent them from developing into major problems that require costly repairs.
Proper Attic Ventilation
Proper attic ventilation plays a fundamental role in extending the life of your shingles and maintaining the overall health of your roof. Good ventilation helps regulate temperature and moisture levels in your attic. Which prevents issues like ice dams in winter and excessive heat buildup in summer.
We recommend you to be certain that your attic has adequate intake and exhaust vents. The exact requirements will depend on factors like your roof’s size and pitch, as well as local climate conditions. A professional roofer can assess your attic’s ventilation and make recommendations for improvements if necessary.
