We’ve been working on finalizing our full building permit with the City and coordinating new water service and underground plumbing. Our recent progress has kept us busy, but unfortunately we’ve been a little behind in our blog posts.
So to catch up, check out our rebuilt back roof. Our back roof is a low slope roof, meaning it has a rise to run ratio of less than 1:12. We installed a bitumen roof with two layers of polyisocyanurate insulation. We installed Johns Manville Energy 3.E insulation board. JM 3.E is unique in that it maintains the same R-Value (insulating factor), but is free of Halogenated Flame Retardants (HFRs). HFRs have been linked to many health and environmental problems- including respiratory issues and cancer. Johns Manville has developed a product that performs to the same level as competing products, without the dangerous HFRs, which aligns perfectly with our goal of prioritizing healthy and environmentally conscious products.
Sourcing an insulation board without HFRs was not an easy task. We worked directly with Johns Manville, but finding a supplier to deliver the product was difficult. We had to correct the wrong product being delivered, the wrong dimension of insulation delivered, and paying almost a 100% markup to finally source the correct product.

- Sheathing in progress
- Materials staged and ready to go in the front of the house- JM Energy 3.e.
- Rolls of tar paper, this is the glue that adheres our insulation to the roof and creates a water tight barrier.
