When installing asphalt shingles, start by ensuring the roof deck is clean and dry, then lay down a waterproof underlayment. Nail each shingle in staggered rows from the bottom edge upward, overlapping them to shed water effectively. It's important to align each course carefully to avoid leaks, and to use proper flashing around vents and chimneys to seal everything tight.
