Roof sheathing - TechShield versus Zip System
We are building a 1,600 sq. ft. addition; it is being added to a 1930's farmhouse in the Richmond, VA area (Zone 4, mixed humid). Detail summary: walls are 6 1/2" SIPs, truss roof (see attached file) with partial cathedral ceilings (1 ft. extra heal height for insulation), roof insulation planned is blown-in cellulose (vented attic), conditioned crawl with 2" thermax at interior foundation walls, etc.
We are in the process of deciding on the roof sheathing. The roofing material will include Energy Star rated shingles. My question concerns the roof sheathing. One of our contractors uses Techshield; another I'm considering is the Zip System roof sheathing. Any thoughts on which way to go?
