Asphalt Shingle Roof Planning
Compare shingle system, slope, exposure, and accessories.
The useful comparison is broader than a sample or sales claim. Put slope and deck substrate, shingle product and exposure, underlayment and eave treatment, starter, ridge, and ventilation details, and flashing and manufacturer instructions into the same written project record. Stay on the ground or in a safely accessible interior area. Roof access, destructive inspection, and installation belong with qualified people using proper protection.
Planning factors
Five decisions worth documenting
Use the headings as a proposal check. The actions beneath them are specific to this project decision.
Slope and deck substrate
Verify the roof slope and deck type before selecting a shingle assembly. A product intended for one slope range may require a different underlayment approach elsewhere.
Shingle product and exposure
Record the exact shingle, color, exposure, and applicable product classification. Ask how field fastening and sealing follow manufacturer instructions for the actual roof and exposure.
Underlayment and eave treatment
Have the proposal name the underlayment and eave treatment, including how they connect at valleys, walls, penetrations, and edges. These layers are not interchangeable merely because they are hidden.
Starter, ridge, and ventilation details
Starter courses, ridge caps, and ventilation accessories should be identified as products or details. Confirm that the ridge arrangement fits the planned attic assembly.
Flashing and manufacturer instructions
Ask for completed flashing and transition records before relying on a finished shingle photograph. The attractive field surface does not show every water-shedding junction.

Before authorizing work
What record belongs with “slope and deck substrate” before work begins?
Request a dated description and the evidence supporting the proposed treatment. Cross-check entries: shingle product and exposure; underlayment and eave treatment. Named responsibility: starter, ridge, and ventilation details. Closeout file: flashing and manufacturer instructions. Identity check for Asphalt Shingle Roof Planning: confirm the business, applicable County license, roofing insurance, and current Harrison permit steps separately.
