Installing asphalt shingles correctly is crucial for the longevity and durability of your roof. Here are ten essential steps to follow for a successful installation:
- Prepare the Roof Deck:
Remove any old roofing material and ensure the roof deck is clean, dry, and free of any protruding nails or debris.
- Install Drip Edge:
Install a drip edge at the eaves to ensure water runoff is directed away from the fascia and into the gutters.
- Lay Underlayment:
Roll out and secure the roofing underlayment across the entire roof deck, overlapping each row by a few inches to create a waterproof barrier.
- Install Drip Edge on Gable Ends:
Now install the drip edge along the gable ends of the roof, securing over the underlayment.
- Lay the Starter Course:
Lay your starter course of shingles along the eaves, ensuring they overhang the edge by about a centimetre. The starter course prevents water from seeping into the roof deck.
- Lay the First Course of Shingles:
Starting at the lower corner of the roof, begin installing your first course of shingles, working from the bottom up and following the manufacturer’s instructions for proper placement and nailing.
- Cut the First Shingle of Each Row:
To create a staggered pattern and avoid leaks, cut the first shingle of each row. The cut should be different for each row.
- Install Flashing:
Install flashing around any roof penetrations like vents, chimneys or skylights, and anywhere two roof surfaces meet, to prevent leaks.
- Install the Ridge Vent and Cap:
To ensure proper attic ventilation, install a ridge vent along the peak of your roof, then cover with cap shingles.
- Clean Up and Final Inspection:
Clean up any debris and give your roof a final inspection. Check for and correct any raised nails or misaligned shingles.
