Maplewood Multifamily.
Overview
22 households. 22 different routines.
A 22-unit multifamily building in Roswell with a chronic ponding-water issue and seam separation that had triggered three insurance claims in 18 months. The board approved a full re-roof but only if residents could stay in their units.
We installed an 80-mil mechanically-attached TPO with a re-engineered tapered insulation scheme that redirected drainage from the formerly-pooling NW corner to two new scuppers. Hand-delivered notices to every unit, posted a daily project log in the lobby, kept noise-impact windows to 9am-4pm Mon-Fri, and the residents never had to leave.
Drainage redesign
Three claims, one root cause.
A roof that finally drains.
The NW corner had been a problem since 2007 original construction set the slope at 1/8":12 and over time the deck deflected another 1/4". Three roofers before us patched the resulting ponds.
We re-engineered the slope with tapered polyiso (1/2":12 from new high points), added two scuppers through the parapet, and tied it into the gutter system below. The roof drains in 14 minutes after a 1" rain event. It used to take 8+ hours.

Three roofers told us the ponding was just "how it is." Premier solved it on day one of design. That alone paid for the project.
