Asphalt shingle roofing starts with a tear-off: remove old shingles and felt, inspect the plywood roof deck, then install felt underlayment with ice-and-water shield.
Nail architectural shingles with ring-shank fasteners and seal the valleys and ridge cap with roofing cement.
Three-tab and architectural shingles resist Orlando's humidity and summer algae, though architectural's dimensional laminated design handles heat better.
Flashing at chimneys and pipe boots, plus counter-flashing at the soffit line, stops water from wicking into the fascia.
Shingle roofing lasts 20–25 years in Orlando's heat and humidity with ridge vents and soffit ventilation. Ice-and-water shield under the starter course stops summer downpours.
Quality underlayment and flashing prevent water from rotting the plywood sheathing and trusses.
