Index 01 — Practice

An exterior systems firm operating at the intersection of architecture, construction management, and long-horizon asset stewardship.

We work alongside property managers, owners, developers, and design teams to specify, install, and steward roofing systems engineered to outlast the desert climate they sit beneath. Every engagement is led by a project director, every spec is documented, every deliverable is auditable.

Index 02 — Systems

A working library of roofing systems, matched to building, climate, and lifecycle.

We design specifications around the building's use, structure, and time horizon — not around what a single manufacturer happens to sell.

01

TPO
Single-ply membrane

Application
Low-slope commercial
Thickness
45 / 60 / 80 mil
Warranty
15 – 30 yr NDL

Thermoplastic polyolefin remains the workhorse of the Southwestern commercial portfolio. Heat-welded seams, high solar reflectance, and a service profile that pairs cleanly with rooftop equipment and solar arrays.

02

PVC
Single-ply membrane

Application
Chemical / grease exposure
Thickness
50 / 60 / 80 mil
Warranty
20 – 30 yr

Specified where rooftop conditions are chemically aggressive — restaurants, light industrial, and facilities with sustained grease or hydrocarbon exposure. Greater dimensional stability than TPO in extreme heat cycling.

03

Modified
Bitumen

Application
Plaza decks · podiums
System
SBS / APP, 2-ply
Warranty
20 – 25 yr

For roofs that double as occupied terrace or amenity space, or where redundancy is a structural requirement. Multi-ply assemblies engineered for foot traffic and the realities of intensive equipment loading.

04

Tile, Standing
Seam & Shingle

Application
High-performance residential
Materials
Clay · concrete · Zn-Al · architectural
Warranty
30 – 50 yr

The residential portfolio leans toward standing seam and clay tile — assemblies that hold up architecturally and weather decades of Sonoran sun. Detailed underlayment and flashing standards are non-negotiable on every project.

Each system is paired with a written specification, manufacturer approvals, and a documented installation protocol kept on file for the life of the warranty.

Index 03 — Property Types

The buildings we take on. And how we approach them.

Every property type carries its own failure modes, access constraints, and ownership horizon. These are the ones we're built for.

Tell us about the
building. We'll take it
from there.

Most engagements begin with a thirty-minute conversation and a brief on-site walk. There is no estimating funnel. There is a project director and a written next step.
