Before You Begin: Essential Prep Work

Before beginning installation, be certain you have everything needed: 

• Safety gear: It includes sturdy work boots, gloves, and glasses. In cases involving steep roofs, it would also include harnesses with fall protection systems in case any accidents should arise during work on roof surfaces.
• Tools and Materials: You’ll need a hammer, shingle nailer, utility knife, chalk line, tape measure, margin trowel, shingles, starter strips, roofing nails, underlayment, and ice and water shield (if required).
• Clear weather: Avoid applying shingles in windy, rainy, or freezing conditions.

Step-by-Step Guide to Shingle Application

1. Install the Starter Strip

A starter strip – typically composed of modified asphalt shingles – offers a level and secure foundation for installing the first row of shingles. Begin by aligning it with the eaves (the horizontal edge that overhangs the wall), making sure it extends past it by about 1/2 an inch; use roofing nails according to the manufacturer’s recommendations to secure the starter strip in position.

2. Laying Down the First Course of Shingles

Laying the initial course of shingles is key for creating an even and straight starting line across your entire roof. Start from the lowest edge, working your way upward. Overlap the starter strip by about an inch before using roofing nails according to manufacturer recommendations for secure attachment of each shingle.

3. Shingle Up

When complete, go back over them once more using roofing nails until shingling up! Once the first course of shingles is in place, subsequent courses must follow a specific pattern to overlap properly and waterproof properly. Here’s the general process:

1. Shingle Alignment: Each shingle should overlap its predecessor by 6 inches to replicate its characteristic tabbed design and ensure waterproof protection from leakage.
2. Nailing: To achieve optimal results, utilize the manufacturer-recommended number and placement of nails per shingle. Nails should typically be driven through designated nailing areas to not penetrate the upper layers of shingles above.
3. Staggering: For an attractive appearance and uniform roofing surface, stagger the starting points of each row by half a shingle relative to those below, creating an “ivy-leaf” pattern and eliminating seams running the full length of your roof. This also reduces potential seams at joints between roof panels.
4. Cutting Shingles: Once you reach the edges and ridge of the roof, cutting shingles into place requires precise cuts using both a utility knife and a straightedge for precise cuts. For best results use both devices for making clean cuts.

4. Valley Application

When two sloping roof sections meet, special consideration must be paid when flashing and applying shingles over valley flashing in valley areas. Follow all manufacturer-provided installation and application guidelines when doing this work.

5. Roof Ridge Cap Installation

Ridge caps can add an attractive finishing touch to the peak of a roof by covering its peak and adding proper ventilation underneath it. Follow manufacturer specifications when applying and placing it securely to ensure proper airflow beneath.

6. Cleaning Up

Once the shingle application has been completed, remove and dispose of all debris responsibly. Inspect the roof for loose nails or improperly secured shingles before continuing. Address them before moving on with further steps in this phase.

Important Considerations and Tips

• Always abide by the manufacturer’s installation requirements for each shingle type you install – depending on their shape, installation requirements may differ in regards to overlap, nailing patterns, and ventilation requirements.
• Assuring proper ventilation from the bottom up will allow moisture to escape while also avoiding trapped heat and condensation using caution on steep roofs if working alone may compromise safety issues; always seek professional help first if unsure.
• Never walk directly on newly installed shingles without first using a walking board to distribute your weight more evenly and prevent damaging them.
