Behind Stratum
A roof is the sum of its parts. So is a good team. We bring the right people, materials and attention together — from the first conversation to the final detail.

One roof. Many moving parts.
01The covering
02The supporting layers
03The finishing details
04The ongoing care
Look beyond the surface. Understand the construction. Keep the details connected. That is the thinking behind our approach to every roof.

Bring compatible materials together as a complete roof system.
Share a clear plan, record the work and explain the next steps for ongoing care.
