About Flat Roof Doctor

Practical repair education, built from real roof projects.

Understand the problem before choosing a repair

Flat Roof Doctor brings together the Ferreira family’s roof-repair videos, project photographs, and field lessons. The aim is to help you identify the roof material, understand the leak, and choose a suitable next step.

What you will find here

• Guides to roof membranes, drains, flashing, skylights, chimneys, and metal details.
• Historical repair videos, with updated written guidance.
• A searchable Bergstrom knowledge catalog and links to product information.
