Commercial Roofing Questions
Should we replace the roof before putting panels on it?
Compare present roof condition with the array's service planning before installation. Pulling panels to reroof underneath adds a second crew, a second schedule and electrical shutdowns. A roof with a few years of life but dry insulation can sometimes be repaired and coated instead, so a moisture survey comes before the verdict.
Can solar go on a standing seam metal roof without drilling?
Often. Seam clamps grip the raised rib, without roof-sheet penetrations where the engineered system and compatible seam profile permit. The panel profile and the clamp must match, and the clamp rating must fit the wind load. We check seam condition, fastener lines and panel gauge before the clamps go on.
Does adding panels void the roof warranty?
The particular warranty document establishes the requirements. We review approval, inspection and alteration conditions with the owner before a mounting detail is committed. We read the warranty first, flash the penetrations to the manufacturer's detail, and keep a record of every one.
What happens to the array when the roof under it leaks?
Panels come off, in sections where the layout allows. The electrician disconnects, we repair or replace the membrane beneath, and the panels go back on. A layout with aisles and labeled strings makes the job small. A packed layout makes it large.
How do ballasted arrays hold up in a hurricane?
Ballast alone is not the full answer. Designers combine weight, wind deflectors and sometimes tie-downs, evaluated for the actual building, location and applicable design requirements. A qualified designer must establish those loads rather than select them from roof use alone. We inspect the roof edges and the ballast pads after a storm, since a shifted block can damage the membrane under it.
