PABCO Roofing's Premier Advantage shingles garner QARC award with Star House installation
The Star House was originally built by a family as a vacation cabin overlooking the beautiful Pacific Ocean. They wanted to honor their Texas roots so they built the house in the shape of the Lone Star. The original roofing and siding on the home consisted of heavy redwood shakes. The homeowner planned an extensive remodel; they wanted to update the appearance and durability of the exterior products.
Fort Bragg is known to experience high winds, heavy rain and frequent fog. The damp, salt air environment seemed to age the wood shakes, so they felt it prudent to go with a more durable product. The general contractor used PABCO® Roofing Products asphalt shingles on his own home in Esparto, California and cabin in the Sierra Nevada Mountains. He had first-hand experience with asphalt shingles and knew how they perform in challenging climates. They chose the shingle that best fit the strict aesthetic and performance requirements of the Coastal Commission.READ MORE >>
They needed an asphalt shingle that would complement the unique design of the house. With so many asphalt shingle choices, they zeroed in on PABCO's Premier Advantage® in Granite. It weighs about 400 lbs. per square and is about as thick as you can find for a standard laminated shingle because it has granules on the back, instead of sand. They loved the Granite shingle because it complemented the house and the ocean backdrop and did not disappear in the bold design of the structure.
When it came to performance, wind resistance was of utmost importance. The house sits on the cliffs overlooking the Pacfic Ocean and there is no protection from the high winds on stormy days. Premier Advantage has a 130 mph wind warranty when applied with 6 nails, so we were confident that it would stand up to the weather. They were also pleased that it had a limited lifetime warranty for peace of mind.
The final step was to get approval from the Coastal Commission, which ensures that products meet strict standards for performance and aesthetics. The roofing choice was approved and the project proceeded without any issues. The roof design was a bit of a challenge, but the roofing crew had little trouble applying the shingles. Premier Advantage Granite was a perfect choice for this home. It not only looks great, but the homeowners have not had any problems with the shingles during high winds. The guest cottage will undergo similar treatment to complete the transformation.
Basalite Interlocking Pavement: a cost-effective, durable alternative
Interlocking Concrete Pavement as an Alternative to Interlocking Concrete Pavement for Howard Road, Westley, California
The implementation of interlocking concrete pavement in heavily loaded applications has gained significant popularity in recent years. From 1993 to 2008, the Port of Oakland completed eight berths with over 6.5 million square feet of concrete pavers for container handling and storage areas. In 2014 Stanislaus County used 170,000 sf of interlocking concrete pavement to replace poorly performing asphalt on Howard Road in Westley, California. This article provides background to this solution which has broad appeal and decades of applications around the world. This is evidenced by over three billion square feet are installed annually in Europe for pedestrian, municipal, industrial and port applications.READ MORE >>
An early version of interlocking concrete pavement dates back to the Roman Empire when The Appian Way was built from stone paving on an aggregate base in 312 B.C. Used as a main route for military supplies, it connected Rome to Brindisi, Apulia, in southeast Italy. The road is 350 miles long about 20 feet wide and has held up for more than 2,000 years. The entire ancient Roman road system servicing their empire was longer than the interstate highway system in the U.S.
The interlocking concrete pavement system offers the advantages of the high compressive strength of concrete and the flexibility of asphalt pavement. The pavers are attractive and provide a traffic calming effect. Research in the United States and overseas has shown that the combined paver and sand layers stiffen or interlock as they are exposed to greater numbers of traffic loads. The resulting resilient modulus is equivalent to the same thickness of asphalt. In other words, the 3.125 inch (80mm) thick pavers and 1-inch thick bedding sand have an AASHTO layer coefficient equivalent to the same thickness of asphalt.
As City Engineer with the City of Ripon, Matt Machado developed interlocking concrete pavement as a roadway standard, adopted by City Council for all new roads and for some pavement rehabilitations. With the standard in place the City constructed more than 1.3 million square feet between 2005 and 2008. This total included the high-profile Main Street in historic downtown Ripon with 50,000 sf of interlocking concrete pavement.
Based on a life-cycle cost analysis, for Ripon, California streets, concrete pavers are approximately 75% of the cost of asphalt concrete over a 100-year period. Maintenance costs for concrete pavers for the same period are approximately 20% the cost of asphalt concrete. Heavier loaded interlocking concrete pavement streets can have a lower life-cycle cost and shorter return on investment as maintenance is generally higher for roads paved with asphalt concrete.
Howard Road in Westley, California
Located in Westley, California at exit 441 on I-5, Howard Road handles a tremendous amount of heavy truck traffic. The Stanislaus Public Works Department was faced with the challenge of designing a long-term, economical pavement solution for the frontage road. Given that the asphalt pavement had failed, the County looked at interlocking concrete pavers as the innovative solution.
Given design parameters of an R-value of <5 for the subgrade soils and a Traffic Index of 11, the Public Works staff designed the pavement section that called for the 80 millimeter thick concrete pavers in a herringbone laying pattern. The pavement section required 14 inches of compacted Caltrans Class 2 aggregate and a layer of biaxial geogrid installed over the compacted subgrade for additional structural support.
Stanislaus County received six bids ranging from $4.50 to $6.00/sf to install the concrete pavers manufactured by Basalite Concrete Products, LLC. Earth Shelter Developers was awarded the concrete paver installation. With businesses such as Denny’s, Chevron and Joe’s Travel Plaza open 24 hours per day, an extensive traffic control plan was implemented allowing the contractor to maintain open drive aisles to accommodate the truck traffic during construction. The project went smoothly and was completed in fall 2014.
Follow Up Pavement Inspection
A follow up visit conducted by Basalite and Stanislaus County in August 2015 showed that the concrete pavers are performing well, even with the extreme conditions in Westley, California. In the heat of the summer, it is not unusual for temperatures to reach 110° F. which can weaken asphalt concrete pavement. Truck traffic on the reconditioned road was non-stop during the site visit.
After finding success in Ripon in lighter load applications, interlocking concrete pavement presents a durable pavement rehabilitation project for Stanislaus County. The innovative pavement is cost-effective, attractive and can hold up to even the toughest loading conditions.
Note: Structural design guidance is available in the following national standard: ASCE/ANSI 58-10 Structural Design of Interlocking Concrete Pavement for Municipal Streets and Roadways as well as Tech Spec 4 Structural Design of Interlocking Concrete Pavements from the Interlocking Concrete Pavement Institute as well as other technical bulletins on construction and maintenance.
Pabco Roofing Featured in 2017 ARMA Installation Contest
ARMA Honors Three Projects as Premier Asphalt Roofing Installations in North America
Three projects from across the United States have been recognized as the top asphalt roofing installations by the Asphalt Roofing Manufacturers Association (ARMA). ARMA’s annual Quality Asphalt Roofing Case-Study (QARC) Awards Program seeks out contractors who choose asphalt roofing and install beautiful and high-performing systems. This year, a stunning home in North Carolina, a commercial building in Florida and a firehouse in Washington State have been chosen as QARC Award winners.
Chapel Hill Roofing Company received the Gold QARC Award for its residential project titled The Triangle Home. The North Carolina-based contractor installed a full asphalt roofing system to fit the home’s complex architecture and the homeowner’s desire for a range of color options, protection from the elements and algae resistance, at an affordable price.READ MORE >>
The Silver Award was given to Advanced Roofing Inc. of Fort Lauderdale, Florida, for the second year in a row. Its completion of a 49,955-square-foot roof on the Broward County Addiction Recovery Center’s Stephen R. Booher Building impressed judges with its intricacy. The new high-performance roof system provides weatherproof protection for the building’s residents.
Cascade Roofing Company of Burlington, Washington, was honored with the Bronze QARC Award for its steepslope installation on the Burlington Fire Department firehouse. The building needed a new roof, and required a product that had visual appeal, wind resistance and algae resistance. Cascade Roofing installed a full asphalt roofing system, including a synthetic underlayment and an ice and water shield on the leading edges.
ARMA received a record 40 submissions this year. These projects demonstrated the range of colors and designs that asphalt roofing can achieve, its ability to meet challenging project requirements and to provide reliability in tough climates. Each year, these projects are judged by a panel of roofing industry experts from trade associations, architecture firms and the media. They score projects based on their use of asphalt roofing technology to provide curb appeal, durability and value.
“As the QARC Awards Program has expanded over the last seven years, it has grown increasingly challenging for our judges to choose from the numerous excellent projects we receive,” said Reed Hitchcock, executive vice president of ARMA. “This year, it came down to identifying which projects demonstrated how contractors use asphalt roofing to solve key challenges for building owners and to provide peace of mind with a protective roof system.” The 2017 QARC recipients are:
