This roof replacement came about because the previous 3-tab shingles kept blowing off. The homeowners decide to upgrade to a new Owens Croning Oakridge Trudef driftwood shingle that is rated for 110 mph. Where the previous 3 tab shingles were only rated for 60 mph. The ventilation was also upgraded as well, the old turbines were removed and decked over. There was a ridge vent installed to help better ventilate the house which gives the roof a longer life. This replacement took one full day for both removal and install.
