Compression-Free™ rooftop attachment for commercial roofs.

It depends on the attachment. Items installed above the roof are commonly considered overburden and excluded from the roof warranty. The U-Anchor® is a galvanized steel plate with a cover membrane matched to your roofing brand, type and color. It attaches to the roof using the same methods the roofing crew already uses, so it is considered a component of your roof and included in the warranty.

Overburden is anything installed on top of the finished roof that is not part of the roof system itself, such as equipment supports, pavers, walkways, ballast, solar racking and sleepers. Roofing manufacturers commonly exclude overburden from the roof warranty, and removing it to reach a leak is typically at the owner's expense. The U-Anchor® is considered a component of the roof, so it is included in the warranty rather than excluded as overburden.

Both ASCE 7-16 and ASCE 7-22 require nonstructural components and their supports to be positively attached to the structure: bolted, welded or otherwise mechanically fastened, without relying on friction to hold them in place. Weighted or ballasted equipment depends on friction, so it no longer meets code requirements. Rooftop equipment has to be anchored with a reliable load path that carries design forces into the building structure. Every U-Anchor® solution provides that load path, with published capacities for your specific application.

A compression seal keeps water out with pressure from a gasket, a plate or sealant. It stays watertight only as long as that pressure holds. Temperature swings, vibration and aging materials loosen it over time, so it has to be inspected and maintained. A Compression-Free™ attachment does not rely on pressure. The U-Anchor® attaches to the roof as part of the roof system, so nothing requires periodic maintenance to maintain your watertight seal.

Less than 5 minutes each. It is installed by the roof crew already on site, using the same methods their crews already use. There is no curing time, no specialty trade and no sealant to maintain afterward.

Yes. All existing rooftop equipment can be retrofitted, whether the roof is new or years old. Mechanical units, pipe runs, stacks, towers and more can be secured to current wind and seismic requirements without replacing the equipment or the roof. Our existing mechanical tie-down and guyed solutions are built for exactly that.

It comes down to wind uplift conditions, seismic requirements and dead load weight. 2000 and 3000 Series plates let you size the attachment to the actual demand instead of over-specifying. Many of our solutions are pre-engineered, and our engineering partners can assist with any custom attachment.

Single-ply, bituminous and liquid-applied membranes. The cover membrane is matched to the roofing brand, type and color, so the finished U-Anchor® reads as part of the roof it attaches to.
