Architectural specification starter
A clean base clause for project documentation.
Suggested performance-based wording
Provide and install an approved M4S stone-coated metal roofing system comprising the selected profiled steel tile with corrosion-protective metallic coating, acrylic bonding system, natural stone-granule finish and protective surface coat; including compatible ridges, barges, valleys, flashings, fasteners, closures and all required accessories. Install to the approved roof geometry, support arrangement, fixing pattern, laps, alignment and weathering details, complete in accordance with the product-specific technical data, approved shop information and project requirements.Insert the selected profile, colour, substrate/coating specification, applicable standard, warranty and project-specific performance criteria before issuing the final specification.
Performance basis
Location exposure, design wind actions, rainfall, slope, drainage and intended warranty.
Execution basis
Support system, fastener type and pattern, laps, junctions, tolerances and inspection points.
Close-out basis
Approved submittals, completion review, cleaning, care guidance and handover documents.
Junction planning library
Six details that decide whether the roof feels resolved.
These are coordination subjects—not generic one-size-fits-all construction details. M4S reviews the applicable condition against the selected profile and building geometry.
Ridge
Ridge-line closure, cap alignment, ventilation intent and weather-resistant termination.
Eave
Starter alignment, drip line, fascia relationship, gutter interface and first-course restraint.
Barge
Gable-edge closure, visual straightness, wind exposure and barge-cap termination.
Valley
Valley width, lining, discharge path, tile cuts, side clearance and maintenance access.
Wall abutment
Apron or sidewall flashing, counter-flashing interface and water-shedding sequence.
Penetration
Pipe or service upstand, compatible flashing, sealant restraint and inspection access.
Design responsibility matrix
Clear ownership prevents technical gaps.
