60 MIL EPDM Flat Roof Installation in Chaska

Flat roofs are not something you can half-do. The system underneath matters just as much as what you see on top - and that's exactly what we're focused on with this flat roof in Chaska.

We're installing a 60 MIL EPDM membrane over fiberboard insulation. The fiberboard layer gives the roof a solid, stable base that helps it hold up against Minnesota's freeze-thaw cycles, heavy snow loads, and the general abuse that comes with living in this climate. Skipping that step is one of the biggest mistakes we see on flat roofs that fail early.

EPDM at 60 MIL is the heavy-duty option. It's thicker, more puncture-resistant, and gives you better long-term performance than thinner membranes. For a flat roof that needs to shed water and stay watertight through brutal winters and wet springs, that thickness is not something we're willing to cut corners on.

You can see the mechanical fasteners laid out in a tight, consistent grid across the fiberboard deck. That pattern is intentional - it locks the system down properly so wind uplift doesn't become a problem down the road. Every piece of this installation is done with the full system in mind, not just the top layer.

Flat roofing done right takes the right materials, the right base, and people who know what they're doing. This is the kind of work we take seriously on every job.
