Malarkey Roofing Shingles Mid-Pacific Institute Hawaii

The second post in this series of historic building roof renovations, features an iconic building in Manoa Valley on the island of Oahu in Hawaii.

Featured in the above video, Honolulu-based roofing contractor MRC Roofing LLC installed Malarkey’s Legacy® shingles in Midnight Black to replace the roof of Kawaiaha‘o Hall. The hall sits among 32 buildings on the 43 acre-campus of Mid-Pacific Institute, an independent, co-educational, college-preparatory school, with 1,580 students.

The Historic Hall

The 62,000-square-foot building was designed by Henry Livingston Kerr and completed in 1908, according to Robert M. Fox and David Cheever at the Historic Hawaii Foundation. “By 1953 however, it was slated for demolition due to its leaky roof and potential fire problems, but was saved when it was discovered that it would cost more to tear it down and build new than to keep the building. Later, in 1983 the building was gutted inside and extensively remodeled to accommodate areas for music, performing arts, communication and foreign language, as well as refurbishment of the library resource center. The renovation won an award from the American Institute of Architects for Richard Kotake, AIA, a Mid-Pacific alum,” wrote Fox and Cheever.

The hall shares its name with the Kawaiaha’o Fountain and Church in downtown Honolulu. According to the Church, the freshwater spring on its grounds was frequented by the High Chieftess Ha’o and thus the Church bears her name: Ka Wai a Ha’o – the water of Ha’o. Similarly, Manoa Valley is also home to consistent rainfall and flowing streams making it both worthy of the namesake, and a prime location for our reliable polymer modified asphalt roofing shingles.

Perpetuating a Legacy

To preserve the award-winning renovation on this historic building, the Legacy® shingle was specified for this job. MRC Roofing has been in business for 31 years in Honolulu, and is the preferred roofing contractor for the school administration. In addition to the shingles, the MRC crew installed other Malarkey products including underlayment, ice & water barrier and ridge.

“We prefer to install Malarkey roofing products whenever possible.  We trust the high quality of Malarkey products, appreciate their customer service and love the durability of the SBS rubberized Legacy® shingle,” said Jon Vaughn, in Estimating and Sales.


For more than 20 years, the Legacy® laminated architectural shingle has been Malarkey’s most popular line. In fact, the same shingles were recently selected to wrap the exterior of a prominent hotel in Portland, the roof of coastal Oregon lodge, and to defend homes against record hail in Kansas City. These laminated architectural shingles are manufactured with an enhanced profile to produce a three-dimensional appearance on the rooftop. They are made of two shingle layers laminated together with an adhesive. On the laminated architectural shingle, the top layer is cut into a saw tooth pattern and laminated to an uncut second layer, known as the “backer” or “shim.” Malarkey applies five lines of adhesive between the two shingle layers for additional strength.

The shingles also feature two lines of specially formulated SEBS polymer modified asphalt sealant to help hold the shingle in place during high winds and heavy rain. This sealant is in the critical lamination area of the shingle for double protection. SEBS asphalt rain sealant is engineered with adhesive properties to join the shingle together and cohesive properties to prevent it from separating.

Completing the Project

The project, in total, took approximately 90 days to complete. The crew tore off the old, wind damaged, and leaking roof. This work required the erection of scaffolding around the entire 3 and 4 story building with a roof pitch of 7:12, according to Vaughn.

In the end, the customer was “extremely pleased with the results of the project,” he said. “Mid-Pac is a previous customer of ours and we have performed more work there since completing Kawaiaha’o Hall.”

“We perform a lot of value added and design build solutions for the school,” added Vaughn. “I feel the term ‘design build’ is an underutilized phrase in the construction industry. [It] should be music to any contractor’s ears and it should be used more by roof owners, in my opinion.”
