Three calculators. Each one solves a problem we've personally cursed about on site.
Pitch, ridge height, rafter length, and per-sheet cut lists for gables, skillions, and roofs.

Open DesignerWe built our internal Dynaspan app to make our own quoting, scheduling, and material take-offs faster. Along the way we built calculators we use every week ourselves — rise/run, slab volumes, flashing designs.
There's no reason these should be locked away. If they save you an hour on site, that's a good day. Use them. And if you need a real shed or patio, we're here.
We do the calculations, the engineering, the permits, and the build. 25-year warranty on every job.
