Tesla’s Metal Roof for Model Y: What You Need to Know
Tesla Inc. added yet another standout item to its ever-growing product line Tuesday — and this time it’s a roof version.
The new 40-foot-by 80- foot one-piece roof has a fabric-covered Air Turret, six skylights and the same colored-to-match outside tiles as Tesla’s 40-foot-by 80-foot glass roof that Cascome took down in January.
The steel roof appears to be the same Tesla featured with a green outdoor color in CEO Elon Musk’s Twitter post. Musk touted that “only 102 of them will be made” and that “when you see it in person, you just stare” against a white background.
“CT has been a leader in advanced automation technology for the past 30 years. This installation is the foundation in our ability to fabricate standalone components that can be delivered to a job site for a turn-key installation,” said John Kupsco, president and founder of Cascome Corp.
Cascome — which partnered with fabrication firm AirInc, Washougal, Wash. —took down a two-panel glass roof on March 1 and started behind it on March 2. Twelve workers Cascome took down in January were brought in, and crews began the process on March 5. All footage and photos documenting Rawlings’ roof removal are owned by Cascome and Dywer.
“Cascome has worked on all of Tesla’s U.S. flagship projects with minor exceptions,” Kupsco said.
Workers used Eco-R containment technology, which kept the work environment clean and provided controlled waste separation to a shipping container.

The project team had access to the underside of the roof — so they could keep the same Tesla solar integration. Cascome worked to leave the existing flashing system in-place during the dismantling phase.
Crews used a Tesla crane to remove the glass roof. A new crane will be supplied on March 18, and crews will begin setting the new steel roof in place.

Musk initially tweeted that “Tesla steel roof tiles are easy to make” and could have associated roll-out release date expectations.
The tweet might make a Colonial-feel roof seem more factory-made than a traditional roof built by local labor arrays provided by a subcontractor (or roofing crew).
Most corporate non-roof product factory-scoped projects that have a smaller scale focus on components, and that is a great way to proactively solve and refine resolution formulae to minimize supply chain variabilities. Scalability, however, is looked at from a solid angle; and the IDEA of scalability may very well differ from one portion of a product line to another.
The fact that Tesla is adding a whole product (the steel roof) to its line may be consistent with the showcase-like product mix that is being showcased at the Tesla Gigafactory 1 within Gigafactory 1 itself.
Recent material cost increase have been expected due to the recently imposed metals tariffs that was strategically planned for.
Graham is right. However, raw material cost is difficult to plan for.
Today, Tesla is inching ever closer to the hiring stage and with that, the scaling of its headcount.
Everyone’s nervously waited for this moment, but who is trailing the workforce numbers more significantly on a solar EOR data-pull — Tesla or Panasonic?
Batteries: Tesla solar batteries have always cost more than LG/Samsung/Sonnen/Redflow solutions. However, those solutions did not significantly scale. Today, standalone battery solutions hit about 500kWh — and Tesla is the only game in town.
Powerwalls 2.0: Production costs of a 3-phase AFCI by make averages out to around $5,000, and the Tesla Powerwall can be priced around $9,000 — behind branding.
Solar Cells — The Metal Roof for Tesla’s Model Y: Earlier this year in late 1st quarter 2019, M_S reported solar cell costs of about 50¢ a Watt. This would bring 400 watts of solar cells deemed as alternatives in conventional shingles by make averaging out to around $200 per cubic foot (1.73 cubic feet = 1 sheet ≈ $340). One way to think about this is that Cascome took down in January ($340) appears to be the same Tesla featured with a green outdoor color in CEO Elon Musk’s Twitter post. Musk touted that “only 102 of them will be made” and that “when you see it in person, you just stare” against a white background.

How is Cascome’s experience with Tesla on the US flagship projects impacting the removal of the two-panel glass roof?
