O'Brien Contracting installs architectural asphalt shingle roofing in Port Charlotte, Florida. Shingle is the most common residential roof system in the state, and in Florida the details that decide how long it lasts are underlayment, nailing pattern, sealed deck and ventilation — not the shingle brand on the box.
UV load, heat cycling and wind uplift are the drivers. Under-nailed shingles, missing starter course, poor ventilation cooking the deck from below, and skipped flashing details cause most premature failures we see in Port Charlotte. Installation quality matters more than the shingle line.
Shingle installations carry our lifetime workmanship guarantee in addition to the manufacturer material warranty for the system selected.
Shorter than in cooler climates because of UV and heat. Manufacturers publish expected life for each shingle line; ventilation and installation quality move the real-world number significantly.
We do not recommend it. A layover hides deck damage, cannot include a proper sealed-deck detail, and shortens the life of the new roof.
Wind performance is a property of the tested assembly and its installation, not the shingle alone. We install to the manufacturer specification required for the rating claimed on the product approval.
