Koolau Roof Tech

Koolau Roof Tech is a roof maintenance company that extends the life of existing shingle roofs instead of replacing them. Its main services are roof health assessments, roof tune-ups and cleaning, and a shingle rejuvenation treatment meant to restore flexibility and granule adhesion. The family-run business has worked on Oahu's Windward side since 1982, and its eco-friendly products are described as safe for pets and plants.

The process starts with an in-person roof consultation, where a technician checks for leaks, shingle wear, vents and flashing, then delivers a written report and recommendations. Free estimates are offered, and treatments are guaranteed for five years. Service areas include Kaneohe, Kailua, Mililani, Pearl City, Ewa Beach, Waipahu and Hawaii Kai, and the company is based in Kaneohe.
