Paradise Roofers — Commercial & Steep-Slope Roofing Estimating
The Problem & Bottlenecks
System Bottlenecks & Technical Friction
Roofing contractors were losing valuable hours calculating complex roof pitches, hip and valley waste factors, and commercial flat roof membrane rolls by hand, frequently under-budgeting flashing and edge metal accessories on competitive bids.
Our Engineering Approach
Architecture Design & Implementation
We engineered a trade-focused roofing estimation system for Paradise Roofers. The platform calculates true slope surface area from plan pitches, automatically determines required squares of shingle or TPO membrane, and accounts for all ridge cap, starter strip, drip edge, and insulation fasteners.
