Existing layers and roof decking
When planning work on an older Hawthorne home, ask what lies beneath the visible roof covering. If the contractor finds spaced boards, an earlier wood roof, or damaged decking, request a written explanation of the preparation needed for the proposed product.
Compare a roof replacement bid with an itemized allowance for hidden damage. Ask how the crew will price extra decking, photograph it, and obtain your approval. If you want to retain a wood appearance, discuss the maintenance and product options for cedar roofing before choosing a substitute.
Check permits for the property and work
Use the permit planning guide to identify the information your permitting office needs. Confirm the jurisdiction, building type, proposed material, structural changes, and any solar work. Ask about historic or other property-specific reviews separately. A neighborhood name does not establish the fee or approval schedule.
Compare bids with the same scope
Use the Hawthorne quote worksheet to organize contractor estimates. Compare quantities, exclusions, hidden-damage allowances, and access costs before comparing totals. A price from another house may cover a different roof assembly or amount of work.
Check who will perform the work
Before choosing a contractor, match the business name on the bid to its license record. Ask who supervises the installation, how changes need approval, and who handles warranty calls. This site provides information and referrals; the contractor is responsible for the work you agree with them.
