Step-by-Step Asphalt Shingle Installation Tips
Here are detailed steps to ensure proper asphalt shingle installation.
1. Prepare the Roof Deck
Before installing shingles, ensure the roof deck is clean, dry, and free of debris.
• Remove any old roofing material or damaged wood.
• Inspect the deck for signs of rot or damage and replace any weak sections.
• Ensure the surface is flat and smooth to provide a stable foundation for the shingles.
2. Install Drip Edge
A drip edge prevents water from getting under the roofing materials and damaging the structure.
• Start at the edges of the roof.
• Nail the drip edge along the eaves and rakes, ensuring it slightly overhangs the roof edge.
3. Lay Roofing Underlayment
Roofing underlayment acts as a moisture barrier to protect the roof deck.
• Start from the bottom of the roof and work your way up.
• Overlap each row of underlayment by at least 4 inches to prevent leaks.
• Secure it with staples or roofing nails, ensuring it lies flat without wrinkles.
4. Install Starter Strip Shingles
Starter strip shingles are essential for preventing water from seeping under the shingles at the eaves.
• Cut the tabs off the shingles to create a straight edge.
• Install the starter strip along the edge of the roof, ensuring it slightly overhangs the drip edge.
5. Begin Installing Asphalt Shingles
• Start at the bottom edge of the roof and work upward.
• Place the first row of asphalt shingles over the starter strip. Align them carefully for a straight line.
• Use roofing nails to secure each shingle. Place nails about 1 inch above the cutouts (nail line) and ensure they are evenly spaced.
• Overlap each row of shingles by about half the width of a shingle to create a watertight barrier.
• Use a chalk line to guide you and ensure straight rows.
6. Install Flashing Around Valleys and Roof Edges
Flashing is important for areas where the roof meets walls, chimneys, or valleys. It prevents leaks in these vulnerable spots.
• Place metal flashing in valleys and around vents, chimneys, and skylights.
• Nail it securely and seal the edges with roofing adhesive.
7. Install Ridge Cap Shingles
Ridge cap shingles protect the peak of the roof and provide a clean, finished look.
• Bend ridge cap shingles over the roof peak.
• Nail them down securely, overlapping each piece for maximum protection.
Common Mistakes to Avoid When Installing Asphalt Shingles
Even small mistakes can lead to big problems when it comes to roofing. Here are common mistakes to avoid during asphalt shingle installation:
• Improper Nail Placement: Nailing too high or too low can cause shingles to come loose. Always nail along the designated nail line.
• Not Using Underlayment: Skipping underlayment leaves the roof deck exposed to moisture, leading to leaks.
• Poor Overlapping: Shingles must overlap properly to ensure water doesn’t seep through the gaps.
• Not Sealing Flashing: Failing to seal flashing around valleys, chimneys, or vents can lead to water leaks.
• Skipping Starter Strips: Without starter strips, water can seep under the first row of shingles.
