The Forsyth Boulevard Office Corridor
The Forsyth corridor between Hanley Road and I-170 is the spine of Clayton's commercial district. The office towers here range from 1960s and 1970s concrete-frame buildings with built-up roofing on structural concrete decks to 1990s and 2000s glass-curtain towers with ballasted EPDM or mechanically attached TPO systems that are now in the middle of their expected service lives.
Older towers on the corridor that have not been reroofed since the 1990s are likely carrying 30-year-old membrane with aging insulation and flashing systems that have been repaired multiple times. We see a pattern in these buildings: the membrane field looks acceptable on a visual inspection, but moisture cores in the parapet zones and above the top-floor office space read saturated. A roof that looked fine on a drive-by assessment turns out to need insulation replacement across 40% of the field area. Our inspection protocol is designed to find that before the replacement scope is written.
