Commercial Metal Roof Restoration

Restoration is a condition-based process that repairs eligible metal panels, fasteners, seams, flashings and penetrations, prepares the surface, and applies a compatible protective or liquid-applied system where appropriate. It is not the same as simply painting the roof.

No. Structural panel failure, severe corrosion, open holes, widespread section loss, failed attachment, wet concealed materials, movement problems or incompatible existing coatings can shift the scope toward selective replacement, retrofit or complete replacement.

Not automatically. Standing-seam systems are designed to move. End laps, transverse seams, penetrations and failed details may require treatment, but vertical standing seams must be evaluated against the panel design and the selected restoration specification.

Loose, missing, backed-out or deteriorated fasteners should be evaluated and corrected before coating. The replacement fastener must be compatible with the panel, substrate, hole condition and restoration system.

No. A coating does not prove that the metal panels, clips, fasteners, substrate or perimeter assemblies meet current project wind pressures. Attachment remains a separate structural and roof-system design issue.

Loose rust, scale and failed coating must be removed or prepared as required. Remaining metal thickness and pitting must be evaluated, and the selected primer or treatment must be compatible with the metal and restoration system.

Potentially, when the metal roof is a qualified substrate and the selected manufacturer allows it. Cleaning, repairs, adhesion testing, primer requirements, seam and fastener treatment, film thickness and warranty requirements still control.

Potentially. Acrylic systems may be appropriate on qualified metal roofs, including reinforced systems, but drainage, surface preparation, adhesion, cure conditions, coating thickness and the manufacturer specification remain important.

Fabric-reinforced systems consume substantially more material than ordinary field coating because material is needed below, through and above the reinforcement as well as at overlaps and details. Standard field-coat coverage rates should not be used.

No. Reflectivity can reduce roof-surface heat gain, but total building energy performance depends on insulation, air leakage, HVAC, interior loads, roof area, color retention and operating conditions.

Aastro uses east of Federal Highway or roughly one-half mile from significant saltwater exposure as a conservative trigger for additional coastal material review. It is an Aastro planning screen, not a universal Florida Building Code distance.

Yes. Aluminum, copper and stainless steel are generally more corrosion resistant than ordinary coated steel, but grade, salt exposure, dissimilar-metal contact, runoff, fastener compatibility, coatings and maintenance still matter.

A retrofit may be considered when the existing roof is not a good coating substrate but the structure and existing system can support an engineered recover assembly. Added load, attachment, condensation, geometry, perimeter details and product approvals must be evaluated.

The existing panel type, condition, repairs, corrosion preparation, fastener and seam treatment, primer, coating or membrane system, coverage and film-thickness requirements, exclusions, wind/attachment boundaries, warranty path, concealed-condition process and closeout documentation.
