Establish whether wood is suitable
Cedar is not a default choice for every climate or jurisdiction. Confirm code acceptance, required fire classification, exposure, and the proposed product before comparing prices.
Shakes and shingles are different
The terms are sometimes used loosely. Ask which product, grade, dimensions, and installation method the proposal specifies. Appearance and installation requirements depend on those details.
Account for the assembly
Ventilation, underlayment or interlayment details, flashings, fasteners, and deck preparation belong in the scope. Moisture management matters as much as the visible wood.
Budget for care, not only installation
Ask what inspection and maintenance the system needs and who can perform it safely. Product selection, local conditions, and care affect how the roof weathers over time.
Make it specific to your home.
This is general planning information, not a diagnosis, quotation, insurance determination, or promise of product performance. A property-specific assessment and written scope are the next steps.
