For Roofing Contractors
Price it, get it approved, get it delivered, put it on
TopHat makes retrofit sub-framing for metal-over-metal reroofs and ships it to your jobsite with delivered pricing. Popular sections ship from inventory; others typically in about three weeks.
Quoting
- What to send for a quote: jobsite ZIP, existing panel profile, roof size, purlin spacing, new panel.
- Quick estimating rule: sub-framing over every purlin takes about 100 ÷ purlin spacing (ft) lineal feet per square. At 5-foot spacing, about 20 lineal feet per square, plus extra members where the engineering tightens spacing in edge and corner zones.
Choosing the product
| Job | Product |
|---|---|
| Straightforward reroof, spec calls for a notched zee | Zee Strip (get a quote to compare with Roof Hugger™) |
| Reroof plus added load (solar, sprinklers, rooftop units, higher design loads) | TopHat Subframe (strengthens purlins) |
| Tight wind design in edge and corner zones | Add Deflection Limiters between purlins |
| Corrugated roof: transite, FRP (fiberglass) or corrugated metal | Quik-Clip (the economical overlay for corrugated and low-profile panels) |
When the spec names another brand
Most specs allow an equal with pre-bid approval. Our substitution guide covers deadlines and what to submit; TopHat Zee-Strip was approved by addendum on a 2024 State of Iowa bid.
