Communication is Key

Distribution Center Undergoes Modern Reroof in Dixon, California

by Ali Turner, editorial assistant

Every once in a while, a job comes along that seems larger than life.  For Environmental Roofing & Waterproofing Inc., Campbell, California, that project came its way in mid-2019, when a 300,000 sq.ft. distribution center needed a new roof. 

         Located in Dixon, California, the building had a huge footprint on a busy street within the Northern California city.  Previously occupied by a national retail chain, the property owner, Nearon Enterprises, wanted to update the building to make it more attractive to potential tenants.  In addition to sprucing up the property, the owner wanted to make the building more modern, which meant looking at innovative roofing systems.  Nearon Enterprises contracted with reputable roofing consultant Kelleher, Boyd & Associates, San Ramon, California, who wrote the new roofing specifications.  With Allen Light, lead inspector, the project quickly began to take shape.  Light conducted bi-weekly inspections and was key in organizing the project, outlining the specifications, and monitoring the safety and flow of the project. 

         The overall reroof project was an exercise in communication for everyone involved.  The roof tear off was accomplished by a 40-man crew from B&M Tear Off Company, Brentwood, California, under the supervision of Felipe Bernal.  Environmental Roofing and Waterproofing was instrumental in keeping the project on schedule, including having daily onsite project supervisors as well as three project managers conducting inspections several times a week.  Environmental Roofing and Waterproofing created weekly schedules for B&M, as well as for Roofline Supply, San Jose, California.  Sean Alboriz, branch manager of Roofline Supply was able to utilize that schedule and have the materials loaded, staged, and ready for installation.

         “By working hand in hand with B&M and Roofline Supply, we were able to create a seamless workflow for the duration of the project to ensure no time was lost,” said Kyle Laubach, vice president of operations, Environmental Roofing & Waterproofing. 

         For the roofing system, Kelleher, Boyd & Associates suggested a Sure-Weld® TPO membrane from Carlisle® over DensDeck® roof boards.  Carlisle’s TPO membranes use advanced technology that contributes to the products’ heat weldability and weatherability.  The combination of a strong polyester fabric and TPO plies provides high breaking and tearing strength, as well as excellent puncture resistance.  As an ENERGY STAR®-certified and Title 24-compliant product, Carlisle’s membrane attributes to a building’s reduction in energy use and cooling costs as well.

         Daylighting was the clear choice for this building for a variety of advantageous reasons.  By lowering the amount of artificial light entering a building, HVAC costs and electricity bills are lowered.  Additionally, studies show that workers enjoy improved health when working within a building that utilizes daylighting.  To accomplish this feature, Environmental Roofing & Waterproofing relied on Sunoptics®, a manufacturer of skylights and daylighting systems.  Working closely with Jonah Cross and Mike Lampkin of Building Enclosure Solutions, the roofing team was guided towards Sunoptics’ Signature™ Series Dome Skylight with dual-hinged smoke hatchets.  These skylights provide glare-free and UV damage-free, full-spectrum natural light.  The vast roofing project required 365 total skylights, all expertly installed by Environmental Roofing & Waterproofing.

         Installing the new Sunoptics Signature Series Dome Skylights also meant establishing safety zones on the floor.  Brett Brennan, safety officer for Environmental Roofing & Waterproofing, was onsite daily and provided safe passage of workers and equipment through the busy jobsite.  Working quickly without sacrificing safety or quality was key, and the contractors amazingly installed 110 skylights in just one day, even in summer temperatures that climbed as high as 110º.  By having 40-50 workers on the roof at a time, the reroof and skylight installation went smoothly, despite the intricate itinerary.  Ed Newman, project manager for Environmental Roofing & Waterproofing, conducted quality control inspections and site checks weekly to ensure a successful installation.

         “By keeping in constant communication with the building owner and the other contractors on the job, we were able to exceed expectations,” said Laubach.  “Working closely with Building Enclosures Solutions, too, was key for us.  Having one point of contact for multiple products who could answer technical questions and provide delivery timelines was essential to our success on this job.”

         “Environmental Roofing & Waterproofing is the type of company you want to work with,” said Cross.  “Their team of seasoned veterans make them a tier-one pioneer in the Bay Area.”
