How Metal performs in Houston

Old through-fastened R-panel roofs leak at thousands of screw holes as neoprene washers dry out and panels expand. A metal retrofit installs sub-framing over the existing roof and a new 24 gauge standing seam panel on top, often without disturbing the tenant below.

Retrofit framing can also convert a flat roof into a sloped metal roof that sheds water, which is a strong option for buildings with chronic ponding and repeated leak calls.

In most cases, yes. The old roof stays in place as a dust and debris barrier while the new roof goes on above it.

It often avoids disposal and interior protection costs, but framing and panels cost more per square foot. It wins on life-cycle cost more than on day-one price.

Heavier gauge panels and Class 4 rated assemblies resist hail well; cosmetic dents are possible, so we review your policy language on cosmetic exclusions.
