Industrial roofing and cladding work crosses several boundaries: roof to wall, sheet to opening, structure to service and contractor to contractor. A material order can be correct while the project brief remains incomplete at these boundaries. Before selecting a sheet or panel, document the building use, existing conditions and planned penetrations. Coordination exposes missing decisions while they are still practical to resolve.
Define the building and operating conditions
Explain whether the work is new construction, replacement or an extension. Record activities inside and whether operations continue during the project. Note known humidity, heat, dust or other exposures for the design team to assess. Use this description to guide product and system discussions rather than turning it into an unsupported performance specification.
Share available structural and service drawings, identifying which are current. If records are incomplete, list areas requiring survey or verification. Existing supports, connections and deterioration need appropriate inspection. New structural dimensions and the suitability of existing support arrangements require qualified engineering review rather than assumptions based on sheet length.
Make a register of every opening
List rooflights, vents, ducts, pipes, doors and other interruptions to roof or wall. For each, record location, approximate size, responsible party and whether equipment is existing or proposed. Add a required decision date so equipment choices are not left until the roof is fabricated or installed.
Ask who designs and supplies the frame, trimming support, flashing and seals around each opening. An equipment contractor may supply a unit without its roof interface. A roofing contractor may price sheet area while excluding specialist penetration details. Put responsibilities in writing and have the relevant parties review the junction together.
Coordinate roof, wall and rainwater details
Review eaves, ridges, corners, roof-to-wall junctions and transitions between materials. The proposal should identify accessories and details needed for the selected system. Ask how movement is accommodated and incompatible substitutions prevented. Technical claims should relate to the exact proposed product or assembly rather than a broad material category.
Trace rainwater from the roof to gutters, downpipes and the agreed discharge point. Include interfaces with existing drainage and identify who connects them. If part of the system remains outside the roofing package, record its condition and the assumptions the new design relies upon. Unclear drainage ownership leaves a significant interface unresolved.
Control changes during procurement and installation
Use an approved drawing revision and product schedule for ordering. If a service opening moves or a product changes, ask which other details need review. Local adjustments can affect supports, sheet layout and weathering interfaces. Record the decision and distribute updated information to every affected contractor before work continues on that detail.
For an occupied building, agree temporary protection and the sequence for exposing interior areas. At handover, collect the final product schedule, relevant drawings and maintenance guidance. Document variations and unresolved items. Future work on plant or services should refer to these records before anyone cuts a new penetration in the completed roof.
Use this decision checklist
| Decision | What to record | Why it matters |
|---|---|---|
| Operating conditions | Use, exposures and occupied work | Informs system selection |
| Opening register | Location, owner and decision date | Prevents late changes |
| Junction ownership | Supports, flashing and connections | Closes contractor gaps |
| Change control | Drawing and product revision | Protects coordination |

Frequently asked questions
Should openings be confirmed before sheets are ordered?
Confirm them early and record unresolved items. Openings can affect sheet layout, supports, flashing and the work of other contractors.
Are panels and roofing sheets interchangeable?
Do not assume so. Compare the exact system, supporting details, accessories, exposure suitability and project requirements with appropriate technical input.
Who handles penetrations made by another contractor?
Agree responsibility explicitly. Identify who designs, supplies, installs and inspects support and weathering details, even when another package supplies the equipment.
