Hawaii's Trusted Roof Maintenance Company


Free Roof Assessment

After we schedule  your appointment, I will send out a free roof measurement report.  This will give us a rough idea of the size of your roof, and you can keep this report for your reference.

On our initial visit, I will thoroughly inspect your roof, focusing on the following areas:

* algae/moss/lichen growth

*shingle degranulation

*missing/loose/cracked shingles

*roof penetrations 

*metal flashings

*potential leak areas

Following our assessment, I will provide a detailed photo report of my findings and recommendations.

Roof Tune-up & Algaecide Treatment

Our roof tune-up will provide the preventative roof maintenance needed to extend the life of your roof and avoid premature failure.  A few examples of issues I will address are:

*nails backing out of shingles

*securing loose shingles

*replacing gaskets on vent stacks

*sealing cracks to avoid potential leaks

*refastening floating flashings


We will also address the black streaks on your roof, caused by algae called gloeocapsa magma.  Our bleach free algaecide solution is biodegradable and eco-friendly preventative treatment.   


For heavily stained roofs, PV, and gutter cleaning,  we have a exclusive partnership with Envirowash Hawaii, Oahu's first roof washing and Soft Wash Systems Certified company.  Like any other trade, experience counts and Envirowash Hawaii is the only roof cleaning company I would recommend.

Roof Maxx Treatment

Similar to applying moisturizer to dry skin, Roof Maxx is gently sprayed onto your roof where millions of micro-beads will immediately begin rejuvenating and restoring the pliability of brittle asphalt shingles.  For an average home, the treatment is quick and clean and can usually be completed within two hours.  Roof Maxx is 100% safe for plants, pets, and people, because it’s an all-natural bio-based product. Any overspray can simply be rinsed away with a hose or with the next rain. Click here for more information on Roof Maxx.


What's Roof Maxx?

As a roof ages, the petrochemical oils dry out and the
shingles' waterproofing asphalt becomes increasingly brittle. Movement-related stresses cause the shingle to slowly break apart, similar to the way a pothole develops in the road.


Roof Maxx is a powerful scientifically-formulated
all-natural treatment that’s 100% safe for people, pets, property, and the environment.


Soy Fusion technology allows millions of micro-beads of soy methyl esters to quickly penetrate aged roof shingles and restore it's flexibility within 72 hours, allowing the roof to freely expand and contract.

Roof Maxx is the world's first sustainable roofing solution. By extending the roof's life we reduce its carbon and environmental footprint.

Roof Maxx allows homeowners to delay the cost of expensive roof replacements and keeps old roofing material out of the landfills.  A Win-Win situation for everyone!

About Koolau Roof Tech

We come from three generations of residential construction experience.  My grandfather, Taro and my father Mel, have both owned successful construction companies located on the Windward side of Oahu.  I grew up working alongside both of them and bring that priceless experience to Koolau Roof Tech.  My name is Kirt Kobashigawa, I'm the owner and operator of this locally owned small business.  Besides learning how to build a home from the ground up, the most important lesson they taught me was how to treat your customers.  Our family has always prided ourselves on building relationships with our clients, and we will continue to provide that local-style five star service.
