WHAT'S NEW AT THE DRAFTING DESK

The tools have evolved. The one-on-one service remains.

Every drawing is prepared by drafting professionals with 29+ years of experience in the roofing and building enclosure industry, using current AutoCAD and Revit software. AI-assisted tools support routine tasks behind the scenes, while our team performs all drafting and quality reviews for accuracy, clarity, and alignment with project requirements.

2D Drafting in AutoCAD & Revit

Precise 2D shop drawings, roof plans and details, drafted to industry standards on your titleblock and delivered as DWG, RVT or PDF.

3D Modeling in Revit (BIM)

One 3D model drives the roof plan, elevations and details, so drains, crickets and penetrations stay coordinated across every sheet.

Drone & Satellite to Plan

Send an address or your drone footage. We return a scaled roof plan on your titleblock, with no tape measure on the roof.

Scan-to-BIM

Client-provided LiDAR and point-cloud data become accurate as-built models and drawings for reroofs and retrofits. You or your surveyor capture the scan; we take it from there.

Moisture Survey Mapping

Client-provided nuclear, infrared or impedance readings become a contoured moisture map, with dry, moist and wet square footage calculated to your ranges. You perform the survey; we draw it.

Drafting & Drawing Review

Already have drawings, in-house or AI-generated? We’ll review and refine them for clean geometry, dimensional accuracy, drafting quality, and compliance with project specs and manufacturer requirements.
