How we can help?

Installation that works for business

We design and install TPO/PVC systems around your hours, tapered insulation for drainage, code/FM attachment, clean close-out, and warranties that pass inspection.

Replace or recover, whichever saves more

We run core cuts and moisture scans, then recommend the lowest total-cost path (recover or tear-off). New edge metals, welded seams, and documented QA keep your space dry with minimal disruption.

Repairs & maintenance that prevent downtime

Fast leak response, drains cleared, seams/flashings fixed, and scheduled inspections, so you control risk, energy costs, and tenant/customer experience.

Systems That Make Business Sense

Casabella installs commercial roofing systems that match your space’s performance and budget needs in Seattle & the Eastside. Our options are durable, energy-efficient, and built to pass inspection with minimal disruption to operations.

TPO Roofing

TPO is a white, reflective single-ply with heat-welded seams. It delivers a clean look and strong value on large areas. We specify polyiso/tapered insulation, the right attachment (mechanically attached or fully adhered), reinforced perimeters, edge metals, and walk pads to manufacturer/FM standards.

Benefits of TPO

PVC Roofing

PVC excels where grease/chemicals are present, ideal for restaurants and mixed-use over kitchens. Welded seams, reinforced membrane, and robust curb/penetration details deliver long service life under tough exhaust conditions.

Benefits of PVC

Flat & Low-Slope Solutions

Complete TPO/PVC assemblies with tapered insulation and crickets to move water, correctly sized drains/edge metals, and service-route walk pads: reducing ponding and extending roof life.

Benefits of Flat/Low-Slope Systems

Roof Coatings

Silicone/acrylic coatings can restore watertightness on qualified roofs (sound deck, controlled moisture). We reinforce seams/penetrations and apply the specified mil build for manufacturer coverage, often with minimal impact on daily operations.
