That combination matters. A material designed for a steeper shingle slope is not automatically the right choice for a flat section. The replacement plan kept the two roof conditions distinct while treating them as one coordinated project.
The existing flat and sloped roofing was removed down to the deck. Once the roof was open, the crew found and replaced deteriorated sheathing before installing the new roofing systems.
Deck condition is one reason a replacement estimate may include an allowance or unit price for concealed wood work. Homeowners can ask how the written scope prices deck repairs that may be discovered during removal.
CertainTeed shingles were installed on the pitched portions of the home. Modified bitumen rolls were installed on the flat roof areas.
Each system served a different roof condition. Roof slope and drainage shaped the material selection for each section.
The completed project pairs CertainTeed shingles on the main pitched roof with modified bitumen on the adjoining flat sections.

Ask the contractor to identify every roof section, the system proposed for each slope, how transitions will be handled, and what happens if deck deterioration is found during removal.
