Clean the roof deck thoroughly, removing large debris and using magnetic sweepers to collect stray nails. Inspect the roof deck for any hidden damage that could compromise the integrity of your new shingles. A detailed inspection will identify potential hazards and ensure the surface is ready for shingle installation.

Magnetic devices or metal detectors can find and remove remaining nails, ensuring homeowner safety and project quality.

Installing Drip Edge

Installing a drip edge is crucial for preparing your roof deck. It should extend at least 1/4 inch over the edge to direct water into the gutters. This component helps prevent water damage by ensuring that water is directed away from the fascia and into the gutter system.

Secure and align the drip edge correctly during installation. This enhances the roof’s durability and contributes to a neat, finished appearance.

Removing Old Shingles

Before you install roof shingles, you must remove the old ones. Start the removal process from the peak of the roof, using a roofing shovel to lift the shingles. This tool is designed to efficiently pry up and remove the shingles from the roof deck.

Removing old existing shingles safely ensures a solid foundation for new roofing materials.

Using a Roofing Shovel

A roofing shovel is more efficient than a garden fork for removing shingles. Its design facilitates shingle removal. Insert the blade under the shingle and leverage it to lift the shingle off safely.

Disposing of Old Shingles

Proper disposal of old shingles maintains a clean worksite and adheres to local regulations. Drop the shingles in a trash bin or designated pile for proper disposal. This keeps the work area tidy and ensures compliance with local disposal guidelines.

Installing Underlayment

Underlayment provides additional protection against water infiltration and adds extra insulation to the roof. Complete the application of underlayment and valley flashing before applying roof shingles.

Types of Underlayment

Two main types of roof underlayment exist: asphalt-saturated felt and synthetic. Asphalt-saturated felt, a traditional underlayment, is created by saturating a paper or fiberglass mat with asphalt and is available in grades No.15 and No.30. Synthetic underlayment, made from polymers, offers better longevity and moisture resistance.

Choose between these options based on budget, desired longevity, and moisture resistance needs. Both types provide essential moisture protection, ensuring a durable roofing system.

Installation Process

When installing underlayment, begin at the eave and overlap each course by at least four inches to ensure proper sealing. Ensure it overhangs the drip edge by 1/4” to 3/4”. Avoid creases or bubbles for a smooth surface. This layer acts as a secondary barrier, enhancing the durability and effectiveness of your roofing system.

A chalk line helps maintain alignment while applying underlayment, ensuring a professional and polished finish.

Flashing Installation

Flashing prevents water damage by protecting the seams and intersections of the roof. It acts as a barrier against water leaks around roof structures such as chimneys, skylights, and vents.

Applying roofing cement to the edges of shingles around these structures enhances waterproofing and prevents leaks.

Metal Flashing

A drip edge, a metal flashing, directs water away from the fascia and into the gutter, preventing water damage. Measure the perimeter of the roofing areas to determine the amount of drip edge flashing required. Proper installation places the drip edge under ice and water at the eaves and over it on rakes.

A comprehensive post-installation inspection checks for issues like leaks and structural integrity, ensuring all components are correctly installed.

Ice and Water Protector

The ice and water protector prevents ice dams and adds water-shedding protection, especially in cold climates. Install it along the roof edge, extending at least 24 inches inside the vertical extension of the wall.

Laying the First Row of Shingles

Laying the first row of shingles sets a solid foundation for the rest of the roof. Start by placing a narrow row of shingles along the roof’s edge to establish a base for the first full row.

Proper shingle overlap ensures both aesthetic appeal and functional water resistance.

Starter Strip Shingles

Starter shingles, the first layer at roof edges, ensure water runoff and prevent leaks. These can be either designated starter shingles or standard three-tab shingles used at the roof edges.

Proper installation of starter shingles ensures a durable and waterproof roofing system.

Aligning the First Row

A chalk line helps maintain straightness in shingle arrangement. Snap a chalk line along the bottom edge before laying shingles to establish the first row.

Aligning the first row of shingles ensures a professional finish on your roof.

Installing Shingle Courses

Follow the manufacturer’s suggested layout and mounting technique for a successful installation. Properly cut shingles to ensure a tight fit and prevent gaps that could lead to leaks.

Use a utility knife or specialized shingle cutter to trim shingles for a snug fit around roof features, minimizing gaps.

Overlapping Shingles

Proper shingle overlap prevents potential leaks and moisture ingress. Each course should overlap by at least six inches to effectively channel water off the roof.

Stagger shingles properly to avoid a straight line vertically across the roof, which can compromise integrity and aesthetic appeal.

Nailing Technique

Proper nail placement and driving them flush without cutting into the shingle ensures wind-resistance. Use nails at least two inches long for adequate penetration into multiple layers.

Longer nails, typically at least two inches, are recommended for anchoring ridge cap shingles. Nail down the final ridge cap piece and cover the nail heads with asphalt roof cement for sealing.

Working Around Roof Structures

Properly cut shingles to accommodate these features while maintaining a watertight seal. Proper alignment around these structures prevents water intrusion and maintains the roof’s integrity.

Cutting Shingles to Fit

Use a utility knife for precise cuts when fitting shingles around roof structures. Some installers prefer to cut shingles after they are applied, allowing for precise adjustments along the edge.

A circular saw can be effective for cutting shingles, especially on hip roofs, when combined with a snap line for guidance. Ensure cuts fit around roof features like vents or chimneys for proper sealing.

Sealing Edges with Roofing Cement

Sealing edges with roofing cement prevents water leaks that can cause significant damage. Apply roofing cement along the edges of shingles or flashing, ensuring a good bond to prevent water infiltration.

Ensure the surface is clean and dry before applying roofing cement. Use a putty knife to smooth it out evenly for effective sealing.

Installing Ridge Cap Shingles

Separate ridge cap shingles where perforated and bend them over the roof peak for installation. Properly install by bending the shingles over the ridge and securing them with nails.

Placing Ridge Caps

Installing ridge cap shingles ensures maximum durability and resistance against wind damage. Start at the end opposite the prevailing wind direction for optimum wind-resistance.

Securely nailing down ridge caps maintains the durability and weather resistance of your roof.

Securing Ridge Caps

Use longer nails to ensure proper penetration when nailing ridge cap shingles. Seal the last ridge cap piece by nailing it in place and covering the nail heads with asphalt roof cement.

Finally, seal the last ridge shingle with roofing cement for added protection.

Clean-Up and Inspection

After completing the installation, conduct a thorough clean-up to remove leftover materials and debris. Lay tarps around the work area to collect debris, simplifying the clean-up process.

Place old shingles in a rental trash container to facilitate proper disposal and avoid cluttering the worksite.

Removing Debris

Using a leaf blower can expedite the removal of leaves and debris from the roof surface. It is essential to remove debris safely from the roof to prevent accidents and ensure a clean work area.

Always handle debris with care and dispose of it properly to avoid creating hazards.

Final Inspection

After debris removal, inspect the roof for stains or growths to identify potential issues. Proper disposal of debris not only enhances safety but also prevents potential hazards from sharp or heavy materials left on-site.

Conducting a final inspection ensures that the newly shingled roof is free of issues and ready to withstand the elements.
