When property owners compare shrink wrap enclosure quotes, they sometimes discover significant price variation that seems unexplained. One common explanation is the roof geometry. Flat commercial roofs and pitched residential or institutional roofs require fundamentally different installation approaches.
Flat Roof Enclosures
Flat commercial roofs typically use a drape-and-seal method: film is laid across the roof field, pulled down the parapet, and heat-fused at overlaps and edges. Penetrations such as HVAC curbs, drains, and vents require individual sealing with formed shrink wrap boots or compatible tape products.
Pitched Roof Enclosures
Pitched roofs require a ridge-anchored tent system: film is attached at the ridge, draped down each slope, and secured at the eave. The geometry creates runoff pathways that direct water away from the building, but the installation requires working on slope, which increases labor time and safety requirements.
Hip and Complex Geometry Roofs
Hip roofs, mansard roofs, and complex multi-slope geometries require custom panel layouts and more heat-fused seams, the most labor-intensive category. StormWrappers estimating accounts for roof geometry in all project bids.
