This project involves the complete removal and disposal of existing roofing materials on both sloped and flat roofs, including the patio roof. The roof decking will be inspected and repaired as needed to ensure a solid foundation. A white granulated torch-applied Bituthene membrane will be installed on the flat roof for waterproofing, while a 30-pound underlayment will be applied on the sloped roof beneath new 30-year asphalt shingles. Additional components such as metal valley flashing, drip edges, starter strips, plumbing and AC flashings, and ridge caps will be installed to ensure a durable, weather-resistant roofing system that meets owner specifications.
1. Remove and properly dispose of the existing single layer of asphalt shingles on the sloped roof. 2. Remove and haul away the existing single layer roofing system on the flat roof. 3. Remove and dispose of the existing patio roof structure. 4. Inspect all exposed roof sheathing for any damaged or deteriorated sections and replace as necessary to ensure a sound substrate. 5. Install a white granulated torch-applied Bituthene membrane over the exposed wood sheathing on the flat roof to provide a durable waterproof barrier. 6. Install a 30-pound synthetic underlayment over the wood sheathing on the sloped roof to enhance water resistance beneath the shingles. 7. Install 18-inch metal valley flashing to ensure proper water runoff in roof valleys. 8. Install 2-inch by 2-inch metal drip edge along the roof eaves on the sloped roof to protect the edges and direct water away from the fascia. 9. Install starter strips around the roof eaves to secure the initial row of shingles and improve wind resistance. 10. Install 30-year asphalt shingles in a color selected and approved by the owner, ensuring proper alignment and fastening. 11. Install new plumbing and air conditioning flashings to maintain waterproof seals around roof penetrations. 12. Install ridge cap shingles along the roof ridge line to provide a finished appearance and prevent water infiltration.
