Kahului, HI Roof Installation & Repair | 15+ Years

Roof Replacement

GAF Timberline HDZ shingles with StrikeZone nailing area for Class 4 impact resistance rated to UL 2218. We install the full GAF Roof System. Cobra ridge vent, FeltBuster synthetic underlayment, Starter Match starter strip, and Seal-A-Ridge caps. That qualifies your Kahului home for the Golden Pledge warranty: 25-year workmanship plus 50-year material.

Roof Repair

Step flashing at chimney walls is the number one leak source we see in Kahului. Improper step flashing causes roof leaks. It's that simple. We install new step flashing with a chimney cricket for proper water diversion, sealed with Geocel tripolymer sealant. Fix it once, fix it right.

Storm Damage Repair

Wind speeds over 60 mph cause shingle tab lift and seal failure. Hail over 1" diameter causes fractures through the shingle mat to the fiberglass reinforcement. Our HAAG-trained inspectors know the difference between cosmetic damage and functional damage. That distinction determines your insurance payout.

New Roof Installation

New construction roof installation following IRC Section R905 and local Kahului building code amendments. We calculate ventilation per IRC R806 (1:150 ratio reduced to 1:300 when 50% is within 3ft of ridge. Synthetic underlayment per ASTM D226, ice barrier per ASTM D1970 at eaves in freeze-thaw climate zones. Manufacturer-certified installation locks in the full system warranty.

Metal Roofing

We do metal roof repairs too. Loose panels, failed sealant at transitions, rust spots on older galvanized. Not every metal issue needs a full replacement. Our Kahului crew can usually fix it same-day.

Shingle Roofing

Your shingle choice determines your warranty, your curb appeal, and how your roof handles Hawaii weather. We'll show you samples, explain the differences, and let you pick what fits your budget. No pressure.

Flat Roofing

Flat roofs need special attention. Water doesn't run off, it sits. We install TPO, PVC, EPDM, and modified bitumen systems designed to handle ponding water in Hawaii's climate.

Commercial Roofing

Roof coatings can extend the life of your commercial roof by 10-15 years for a fraction of replacement cost. We apply silicone and acrylic coatings over existing TPO, EPDM, and metal substrates. Not every roof qualifies. We'll be straight with you.

Gutter Installation

Improperly sized gutters cause fascia board rot and foundation erosion. We calculate gutter capacity using the rainfall intensity formula: roof square footage x pitch factor x rainfall rate (inches/hr for Kahului). Standard 5" K-style handles 5,520 sq ft of effective roof area. Bigger roofs or steeper pitches need 6" gutters with 3x4" downspouts. We hang with hidden hangers screwed into rafter tails every 24".

Roof Inspection

Our 27-point roof inspection covers: shingle condition, granule loss, nail pops, lifting tabs, ridge cap integrity, valley flashing, step flashing at walls, drip edge, pipe boot seals, vent function, soffit ventilation, gutter pitch, downspout capacity, fascia condition, decking (from attic if accessible), and visible signs of moisture in the attic. Written report with photos emailed same day.

Emergency Roof Repair

Emergency tarping is the first priority. We cover the exposed area to stop water entry, then schedule the permanent repair once conditions allow. We don't charge extra for emergency tarp jobs. It's part of the repair cost.

Skylight Installation

We install, replace, and repair skylights in Kahului homes. Fogged glass, cracked frames, persistent leaks around old skylights. We fix it all. Sometimes replacing a 20-year-old skylight is cheaper than trying to repair it.
