Metal Roof

Switching from shingle to metal is a material change, one of the situations where a permit is commonly required even where a like-for-like shingle re-roof is exempt. The roof deck gets checked first to confirm the change is feasible.

Metal roofing costs more up front than asphalt shingle but typically lasts far longer, the trade-off Austin homeowners weigh.

Metal roofing systems are part of Zilker Roofing's commercial roofing scope for low-slope and light commercial buildings.

Metal roofing is a long-life replacement system Zilker Roofing installs for Central Texas homes.

A metal roof is delivered as a metal roofing service: panel profile, gauge, finish and attachment are chosen for the structure before any panel is ordered.

Galvalume is the substrate under most modern steel metal roofs: the aluminum-zinc coating grade (AZ50 vs AZ55) sets the corrosion warranty before any panel or paint decision is made.

Metal resists hail well, but a large stone can still dent a panel. On metal the question after a storm is whether the finish, the seams, and the flashings were compromised — a dent alone is not the same as a leak path.

Metal panels handle wind well when they are fastened correctly, so wind failures on metal almost always start at the perimeter — edge metal, terminations, and the fasteners holding them. A panel lifting at an eave after a storm is worth looking at even when nothing is missing.

Metal roofs leak at fasteners, seams, and flashings rather than through the panels. Exposed-fastener panels rely on rubber washers that dry out in the Texas sun; standing seam hides its fasteners and has far fewer of those failure points.

Metal changes the replacement math on age: a metal roof lasts 40 or more years with proper installation, against 10 to 15 for shingle in the Austin sun. A homeowner facing a second shingle replacement is usually the one who should be pricing metal.

Metal systems raise replacement cost relative to asphalt shingle, in exchange for longer service life.

Zilker Roofing installs metal roofing systems as a longer-life residential replacement option.

Metal roofing is among the commercial systems Zilker Roofing repairs and replaces, alongside TPO, PVC, and modified bitumen.

Metal roofs take the EDM flashing kit, whose pieces interlock with the roofing material for a weathertight installation.

When a metal roof is quoted for a house, confirm which system it is: 'metal roof' covers both standing seam and screw-down panel, and the two differ more from each other in lifespan and maintenance than shingles differ from either.

Most metal-versus-shingle math quietly assumes standing seam; run the numbers again if the metal bid is screw-down panel, because its gasket-maintenance clock erodes the lifetime-cost advantage the comparison is usually sold on.

Metal's energy advantage comes from reflective coatings, not the metal itself - an unpainted dark metal roof absorbs heat about like dark shingles do, while a 'cool' coated one can cut summer attic gain sharply.
