Is Modex a DaVinci Authorized installer?

No. Modex installs DaVinci synthetic slate but is NOT a DaVinci Authorized installer. DaVinci's 50-year limited lifetime product warranty registers in the homeowner's name regardless of installer credential. Our lifetime workmanship warranty (current owner) covers the install. The non-Authorized path doesn't reduce your product warranty.

How much does DaVinci synthetic slate cost in Minneapolis?

$50,000 to $95,000+ for a typical Twin Cities home depending on product and roof size. Bellaforté Slate runs $55K-$90K+ (the most common pick). Bellaforté Shake runs $50K-$85K. Multi-Width Slate runs $60K-$95K+ for the heaviest natural-slate aesthetic. Single-Width Slate runs $55K-$85K for a uniform look. Class 4 impact rating typically qualifies the install for a 10-30% Minnesota insurance premium discount.

Will Country Club or Morningside HOA approve DaVinci synthetic slate?

Usually yes, with proper documentation. Multiple Country Club Tudor and Colonial restorations have been DaVinci-approved. Modex submits product spec, color sample, and install-detail drawings as part of every HOA submission — Country Club, Morningside, Wayzata Bay shoreline review, Edina conservation districts.

How long does a DaVinci synthetic slate install take in the Twin Cities?

Four to ten days on-site for typical Twin Cities homes, depending on roof size, pitch complexity, and dormer count. Material lead time runs four to eight weeks for standard SKUs; eight to sixteen weeks for custom color blends. Owner-led on every install — these projects average $40K+ and warrant direct accountability.

What DaVinci synthetic slate products does Modex install in Minneapolis?

Q: DaVinci synthetic slate vs natural slate for Minneapolis?

DaVinci weighs 2-3 lbs per square foot — the same structural load as standard asphalt shingles. Natural slate weighs 8-10 lbs per square foot and most early-20th-century Minneapolis homes need $5K-$25K in structural reinforcement before installation. Total: DaVinci runs $50K-$90K+; natural slate runs $80K-$150K+ on top of the reinforcement work. DaVinci wins on economics for the vast majority of Twin Cities homes.

Modern Exterior Systems (Modex) installs DaVinci synthetic slate across Minneapolis and the western Twin Cities. DaVinci Bellaforté Slate and Bellaforté Shake are the premium synthetic alternatives to natural slate and cedar — 50-year limited lifetime warranty, Class 4 impact resistance, structural load similar to standard asphalt. We install (not a DaVinci Authorized installer). $50,000 to $90,000+ typical install.

Why Modex installs DaVinci

Modex installs both DaVinci and CeDUR for the synthetic-slate and synthetic-shake categories. DaVinci carries the strongest brand recognition for resale value in Edina and Wayzata real estate comps. When a homeowner in the Twin Cities premium market picks synthetic slate, DaVinci is the default expectation — which is why we install it as our anchor synthetic-slate line.

Honest installer status

We install DaVinci — and we're not an Authorized installer

Modex installs DaVinci synthetic slate using manufacturer-trained methods. We are NOT a DaVinci Authorized installer — that program exists, but we aren't in it. We disclose this on purpose because most contractors who claim "authorized" status aren't. Your 50-year limited lifetime product warranty registers directly with DaVinci in your name through the same pathway regardless of installer credential. Modex's lifetime workmanship warranty (current owner) covers the install.

Why Modex installs DaVinci

Owner-led from measurement through final walk-through. Transparent about our non-Authorized status. Lifetime workmanship warranty stacked on top of DaVinci's 50-year product coverage.

Commitment 1

Owner-led on every DaVinci install

Modex's owner walks every DaVinci job personally — measurement, install, walk-through. These projects average $50K+ and warrant direct accountability.

Modex's owner walks every DaVinci install personally — from the on-roof measurement through the punch-list walk-through. These projects average $50K+, the work is visible on the largest exterior surface of the home, and a tile-by-tile install rewards direct attention. Owner-led isn't a marketing line on a DaVinci roof; it's the reason the install is consistent.

Commitment 2

We install — not a DaVinci Authorized installer

Transparent disclosure: Modex is NOT a DaVinci Authorized installer. We install DaVinci product, but we don't hold the Authorized credential — and your product warranty doesn't care.

Modex is NOT a DaVinci Authorized installer. We install DaVinci product, but the "Authorized Installer" designation is a credential we do not hold. We say so on purpose — most contractors who claim "authorized" status aren't, and the warranty math doesn't change either way. Product warranty is direct from DaVinci, registered in your name, regardless of installer credential.

Commitment 3

Lifetime workmanship on top of DaVinci's 50-year coverage

DaVinci covers the product — 50-year limited lifetime. Modex covers the install — lifetime workmanship, current owner. Two layers of coverage, no gap.

DaVinci's 50-year limited lifetime product warranty covers the tiles. Modex's lifetime workmanship warranty (current owner) covers the install. Together they stack with no gap and no overlap: if a tile fails on the manufacturing side, DaVinci replaces it; if a leak traces to how we set it, we own that on our dime — for as long as you own the home.
