Solution
For the pitched sections, the family went with Landmark from the Viking CertainTeed Asphalt Shingles range. This was chosen because the family liked the soft shadow lines which renders a smooth, refined look that is both striking and classical. They also liked the fact that it was backed by a 30-year product warranty.
For the significant low-slope section of the roof, a robust waterproofing membrane was required. The family decided on Viking Enviroclad as the wide sheets and heat-weldable technology meant fewer seams. This promised a watertight solution, and the product was warranted for a 20-year period which would deliver the assurance the family was looking for.
The Enviroclad Membrane was installed first on the low-slope section of the roof; rising part-way up the pitched sections. Once completed, the CertainTeed Shingles were installed on the pitched sections; overlapping the Enviroclad Membrane sufficiently to negate the chance of any water finding its way into the building.
This allowed the family to achieve the look they desired without making any design concessions.
