This is a Mukilteo Presidential Roof Project where we removed another old cedar shake roof and installed CertainTeed's Presidential TL (Triple Laminate) Composition shingles using all CertainTeed's accessories. Noteworthy is the custom wall vent system installed at the roof-to-wall junctions to allow for proper ventilation without installing multiple "can" vents at the lower roofs. Making for an aesthetically pleasing roof.
