The project at a glance
Your priorities: replace the aging roof, address vulnerable details and choose a system that feels right for your home and budget.
- Roof area: 28 measured squares (2,800 square feet). A 12% waste allowance brings the order quantity to 31.36 squares, rounded up to 31.5 squares.
- Existing assembly: one layer of asphalt shingles over wood sheathing, with a ridge, valleys, pipe penetrations and one existing skylight.
- Details to address: aging pipe boots, weathered edge metal and worn surface areas. Exposed decking will be assessed after tear-off.
- Ventilation: review the intake and exhaust path before finalizing the ridge-vent installation.
These are fictional measurements and inspection notes for this demonstration, not an assessment of a real property.
