Visual Studio

See it on your house before you commit.

Enter your address and we measure the roof from above, in squares and pitch, before anyone comes out. Add a photo of the house and try any color in our catalog on your own roofline, keeping your own light and shadows so it reads like the house rather than a paint chip.

Why Culmen

Specialists, not generalists.

Most roofers install asphalt and will put on a slate or shake roof if you ask. We do the opposite. Lifetime systems are all we install, so every crew, every flashing detail, and every fastener is chosen for a roof that has to perform for half a century or more.

  • Premium-only material

    No builder grades. Every shake, slate, and composite tile is the top of its line.

  • Details built to the same lifespan

    Copper and heavy-gauge flashings, ring-shank fasteners, ventilated underlayment.

  • Manufacturer-backed warranties

    Composite systems carry lifetime limited warranties; we register every one.

  • A clean, respectful jobsite

    Your landscaping, driveway, and neighbors are treated like our own.
