    (D) standard notes for windstorm construction; and
    (E) additional notes for special construction or special conditions; and
  (4) building product specifications, including:
    (A) building product information;
    (B) model code product evaluation reports;
    (C) product evaluations from other agencies;
    (D) manufacturers' test reports if product evaluations are not available; and
    (E) other data to document compliance with codes and design criteria.
(b) To verify that an ongoing improvement conforms to design documents, an appointed qualified inspector must gather information, including:
  (1) the details of connections to transfer wind loads from the roof to the foundation;
  (2) the specifications of roof-cladding components, including:
    (A) a description of roof coverings (these may include shingles, tile, metal roofs, modified bitumen, and low slope roof assemblies);
    (B) the attachment methods of roof anchorages (fastener type and spacing, or other attachment methods); and
    (C) the material of which soffits are made and their anchorage method (fastener type and spacing);
  (3) the roof and floor diaphragm systems, including:
    (A) the roof deck type and anchorage method (fastener type and spacing);
