Roof & Wall Cladding Installation
NLS Contractors installs roof and wall cladding on steel frames in Riyadh, Jeddah, Dammam and Khobar: single skin sheeting, insulated sandwich panels with PU, PIR or rockwool cores, standing seam roofs, flashings, gutters and skylights. Checks cover fire behaviour, wind uplift, water tightness and SBC 601 thermal values. Handover includes panel layouts, a fixing schedule and a water test record.
Cladding is the part of a steel building that people see and the weather tests. This package is the sheeting or panels, the fixings, flashings, gutters, skylights and the sealing between them, installed over a steel frame that is either part of our steel package or already standing.
Single skin sheeting is the lowest-cost option and suits stores and workshops where insulation is not needed. Insulated sandwich panels put two skins around a PU, PIR or rockwool core and suit cold rooms, offices and any building that must keep the heat out. Standing seam roofs use concealed fixings and long continuous sheets, which cuts penetrations and works on low-pitch roofs.
The core decides fire behaviour. Rockwool is non-combustible and is the choice where a fire rating is specified. PU and PIR give more insulation per millimetre of thickness, but the specification has to state what fire performance the panel needs, and Civil Defense requirements apply under SBC 801.
Wind uplift governs fixing spacing. Roof edges and corners see higher suction than the middle of the roof, so the fixing schedule changes by zone. Thermal values for the envelope are checked against the energy conservation requirements of SBC 601. Water tightness depends on laps, sealants, flashings at penetrations and the roof fall, and it is verified by a water test, not assumed.
Roof work needs edge protection, lifelines and safe walkways, and the offer states the access system it uses. The frame survey is requested before panels are ordered, because a frame out of line shows up in the panel joints.
Price depends on area, panel type and thickness, roof pitch and height, the number of flashings and penetrations, and access. Lead time follows the panel type and is stated in the offer. Materials can be sourced through NLS Industries when the client is not supplying them. Send the elevations and roof plan, the panel specification, the fire rating requirement and the site city.

Frequently Asked Questions
Which insulated panel core should I choose?+
Rockwool where a fire rating is specified, PIR or PU where insulation per thickness matters most and the specification allows them. The consultant's fire requirement decides, and the offer prices the core the specification names.
How is a roof tested for leaks?+
By a water test of laps, flashings and penetrations, run before handover and recorded. Any leak found is repaired and retested, and the record goes into the handover file.
What should the client provide before cladding starts?+
A completed frame with bracing, access for lifting equipment, a laydown area, and the approved panel and colour specification. If the frame is not plumb and aligned, panel joints will show it.
Can existing cladding be replaced?+
Often yes, after a survey of the purlins, fixings and frame condition. The offer states what is removed, what is reused and how the building is kept weather-tight during the change.
