Roofing Instructions

A Qualified Person (QP) must perform a structural analysis of the roof to ensure the load capacity is not exceeded before starting work.
Halt roofing activities promptly during severe weather conditions like strong winds or heavy rain.
Ensure materials and equipment for roofs over 16 feet high are supplied via hoisting devices, stairways, or progressive platforms.

Wood Construction Guidelines

All wood used must comply with building codes and design criteria, with inspections for compliance, especially for temporary platforms or fall protection systems.
Implement temporary restraints, like cleats or straps, before manually raising framed walls 10 feet or higher, and avoid relying solely on anchor bolts for blocking or bracing.
Ensure employees don't work or walk on structural members like top plates or joists until they're securely braced and supported.

EM 385-1-1 Paragraph 27-8 (h.–i).

27-8. General Requirements. (h.–i).

h.  Roofing.  (27-8.h)

(1)  A QP must conduct a structural analysis of the roof to assure that the load capacity of the roof deck will not be exceeded prior to the start of work.

(2)  Stop roof work during severe weather (for example, strong winds, electrical storms, icing conditions, heavy rain, snow) as soon as practical.

(3)  Protect roof openings and holes according to chapters 21 and 24.

(4)  On all roofs greater than 16 feet (4.9 m) in height, provide a hoisting device, stairways, or progressive platforms when supplying materials and equipment.

(5)  Secure all roofing materials and accessories when wind speeds are greater than, or are anticipated to exceed, 10 mph (16.1 km/h).  This includes unattached metal roofing panels stored on the roof.

(6)  Provide access and egress to and on roofs or roof sections according to chapters 22 and 24, as applicable.

(7)  Do not store materials within 6 feet (1.8 m) of the roof edge unless guardrails are erected at the roof edge.  Materials that are to be piled, stacked, or grouped must be stable and self-supporting.  (See chapters 14 and 19)

(8)  Personnel working with hot roofing materials (for example, hot mop roofing bitumen, torch applied roofing membranes) must wear the proper PPE (see chapter 5).

i.  Wood Construction. (27-8.i)

(1)  All wood used for construction must meet applicable building codes and design criteria.  Inspect wood used for temporary work platforms or fall protection for compliance with chapters 21 and 22, since structural lumber from the site may not meet the requirements for protective systems.

(2)  Raising Walls.

(a)  Before manually raising framed walls that are 10 feet (3 m) or higher, install temporary restraints (for example, cleats on the foundation or floor system, straps on the wall bottom plate) to prevent inadvertent horizontal sliding or uplift of the framed wall bottom plate.

(b)  Do not use only anchor bolts for blocking or bracing when raising framed walls 10 feet (3 m) or higher.

(3)  Do not allow employees to work from or walk on top plates, joists, rafters, trusses, beams, or other structural members until they are securely braced and supported.

(4)  For wood type construction, an RPE must design the truss support plates, required spacing, temporary bracing, and connection details.
