Aluminum siding is a metal siding material that was commonly installed on older residential homes. It is lightweight, does not rot like wood, and can often be identified by its thin metal panels.

Why It Matters

Homeowners may encounter aluminum siding during repairs, storm damage inspections, or replacement planning. Matching older aluminum profiles and colors can be difficult.

Common Problems

Common issues include dents from hail or impact, oxidation, chalking paint, fading, loose panels, open seams, and trim details that no longer seal or align well. Repairs can also be difficult and expensive, if they are possible at all, because older aluminum siding profiles, colors, and compatible replacement panels may no longer be readily available.

Building Codes & Industry Standards

Aluminum siding repairs and replacement should follow product requirements, exterior wall weather-resistance standards, and local code where applicable.

Exterior Echelon Notes
