Certainteed Landmark georgetown gray. This was a steep roof that was completed in 3 working days. We tore off the existing 1 layer. The roof deck was composed of old boards with large gaps, the edges were uneven. We decided it would be best, with homeowners consent, to install new plywood over the entire roof deck for a flat surface. Also, we installed an ice and water barrier on the low sloped rear roof and replaced an existing skylight with a new Velux skylight.
