Re-roofing is more than just putting new shingles over old. A proper residential re-roof addresses every component of your roofing system, from decking to ridge cap, ensuring your home is protected for decades to come.
Hawaii's climate is exceptionally demanding on roofs. Intense UV radiation degrades materials faster than mainland conditions. Salt-laden trade winds corrode metal components. Heavy tropical rains test waterproofing integrity. High humidity promotes mold and rot. When you're searching for a roofer near me for residential re-roofing, you need contractors who understand these Hawaii-specific challenges.
Why Re-Roofing Matters: Your roof is your home's primary defense against the elements. An aging roof with compromised materials, worn flashings, and deteriorating underlayment can't protect your home effectively. Re-roofing restores that protection with modern materials engineered to withstand Hawaii's demanding environment.
More Than Surface Deep: Quality re-roofing goes beyond the visible roofing material. We address underlayment, flashings, ventilation, and any deck damage discovered during tear-off. This comprehensive approach ensures your new roof performs as designed for its full expected lifespan.
Energy Efficiency: Modern roofing materials offer significant energy efficiency improvements over older products. Reflective shingles, cool roof coatings, and improved ventilation can reduce your HECO bill by lowering attic temperatures and reducing cooling loads.
Home Value: A new roof is one of the best investments for home value. Real estate studies consistently show that new roofs provide strong return on investment, both in terms of resale value and buyer appeal. If you're planning to sell, a new roof removes a major concern for potential buyers.
How do you know when repairs aren't enough and full re-roofing makes sense? These signs indicate it's time:
Roofing materials have expected lifespans, and Hawaii's conditions often shorten them:
Asphalt Shingles: Quality architectural shingles last 20-30 years in Hawaii, though cheaper products may fail sooner. If your shingle roof is approaching 20 years, it's time to plan for replacement.
Metal Roofing: Properly maintained metal roofs can last 40-70 years. If your metal roof is showing significant rust, coating failure, or fastener corrosion, re-roofing may be appropriate.
Tile Roofing: Concrete and clay tiles can last 50+ years, but the underlayment beneath them typically needs replacement every 20-30 years. If your tile roof is 25+ years old, underlayment replacement (which requires removing and reinstalling tiles) is likely needed.
When damage affects a significant portion of your roof, repair costs can approach or exceed replacement costs:
Multiple Leak Sources: If you're experiencing leaks in multiple locations, the problem is likely systemic rather than isolated. Re-roofing addresses the underlying issues rather than chasing individual leaks.
Storm Damage: Severe storms can damage enough of your roof that replacement makes more sense than extensive repairs. Insurance often covers storm-related re-roofing.
Widespread Shingle Failure: If shingles are cracking, curling, or losing granules across the entire roof, spot repairs won't solve the problem. The entire roof surface has reached end of life.
The roof deck (the plywood or boards beneath your roofing material) can deteriorate from moisture intrusion, rot, or age:
Sagging Roof Lines: Visible sagging indicates deck or structural damage that requires immediate attention.
Soft Spots: If areas of your roof feel soft or spongy underfoot, the decking has likely rotted.
Visible Damage: During inspection, visible rot, water staining, or deterioration of decking indicates problems that re-roofing can address.
If you're calling roofers frequently for repairs, the cumulative cost may exceed replacement value:
Repair Frequency: More than one or two repairs per year suggests systemic problems. Track your repair costs. When annual repairs approach 20-30% of replacement cost, re-roofing is the better investment.
Recurring Problems: If the same issues keep returning despite repairs, the underlying roof system has failed and needs replacement.
You can often see signs of roof failure from the ground or attic:
Granule Loss: Check your gutters for accumulated shingle granules. Excessive granule loss indicates shingles are deteriorating.
Curling or Buckling: Shingles that curl at edges or buckle indicate moisture problems or material failure.
Moss or Algae: While common in Hawaii's humidity, excessive moss growth can indicate moisture retention that accelerates deterioration.
Daylight Through Roof: If you can see daylight through your roof boards from the attic, you have serious problems requiring immediate attention.
Quality residential re-roofing follows a structured process that ensures lasting results:
We begin with a thorough inspection of your existing roof, both from above and from the attic space. We assess roofing material condition, flashing integrity, ventilation adequacy, and any visible deck or structural issues. This inspection informs our recommendations and helps identify work that may be covered by insurance.
Based on your preferences, budget, and property characteristics, we help you select appropriate roofing materials. We consider architectural style, coastal exposure, wind requirements, and energy efficiency goals. You'll understand your options and make an informed decision.
We remove existing roofing materials down to the deck. While some contractors offer "overlay" installation (putting new shingles over old), we recommend full tear-off for several reasons:
Deck Inspection: Tear-off reveals any deck damage that must be addressed. Overlaying hides problems that will shorten your new roof's life.
Weight Reduction: Multiple roofing layers add weight that stresses your structure. Hawaii building codes limit the number of allowable layers.
Better Installation: New roofing installs better and lasts longer on a clean, flat deck surface.
Warranty Requirements: Many manufacturer warranties require tear-off to existing deck for full coverage.
With old roofing removed, we carefully inspect the entire deck surface for damage:
Wood Rot: Hawaii's humidity promotes wood rot, especially where leaks have occurred. We replace rotted sections with new plywood or OSB to provide a solid substrate for your new roof.
Shiplap Decking: Older Hawaii homes often have shiplap (1x board) decking rather than plywood. We can repair individual boards as needed or overlay with plywood for a more uniform surface.
Structural Issues: We check rafters and trusses for damage. If structural repairs are needed, we coordinate with appropriate contractors before proceeding with roofing.
Cost Note: Deck repair is typically priced per square foot or per sheet of plywood replaced. Common rates are $40-60 per sheet plus tax for sheathing replacement, or $16-20 per linear foot for fascia and rafter repairs. We identify visible damage during inspection, but additional damage discovered during tear-off is addressed as found.
Before roofing material goes on, we install quality underlayment that provides secondary water protection:
Self-Adhering Underlayment: For superior protection, we install premium self-adhering underlayment like Palisade SA-HT 40mil. This high-temperature underlayment (rated to 250°F) seals around fasteners and provides excellent secondary waterproofing.
Synthetic Underlayment: In some applications, synthetic felt underlayment provides appropriate protection at lower cost than self-adhering products.
Ice and Water Shield: While Hawaii doesn't have ice dams, self-adhering membrane at eaves, valleys, and penetrations provides enhanced protection at these vulnerable points.
Proper attic ventilation extends roof life and improves energy efficiency:
Intake Vents: Soffit or eave vents allow fresh air to enter the attic space.
Exhaust Vents: Ridge vents, turbines, or power vents allow hot air to escape.
Balance: Intake and exhaust should be balanced for optimal airflow. We assess your ventilation and recommend improvements if needed.
We install your selected roofing material according to manufacturer specifications and Hawaii building codes:
Starter Course: Proper starter strips at eaves and rakes provide a foundation for the first course of shingles.
Field Installation: Roofing is installed with proper exposure, alignment, and fastening patterns. High-wind installation protocols use additional fasteners in vulnerable areas.
Hip and Ridge: Hip and ridge caps complete the installation with proper coverage at these high-stress areas.
Quality flashing at all penetrations, transitions, and edges prevents the leaks that most commonly occur at these points:
Drip Edge: Metal drip edge at eaves and rakes directs water away from fascia and into gutters.
Valley Flashing: Valleys where roof planes meet require proper flashing for reliable water management.
Penetration Flashings: Pipe jacks, exhaust vents, and other penetrations receive appropriate flashings rated for Hawaii conditions.
Wall Flashings: Where roof meets wall, step flashings and counter flashings prevent water intrusion.
After installation, we inspect all work to verify proper installation. Magnetic sweepers collect any fallen nails. Debris is removed from your property. You receive warranty documentation and maintenance recommendations.
We work with all major roofing materials appropriate for Hawaii's climate:
The most popular choice for residential re-roofing, quality architectural shingles offer excellent value and proven performance.
CertainTeed Landmark Series: Premium architectural shingles with Class A fire rating, high wind ratings (up to 130 mph), and algae resistance. Available in dozens of colors to complement any home style.
GAF Timberline Series: America's best-selling shingle, featuring dimensional appearance, excellent wind resistance, and comprehensive warranty coverage.
Class 4 Impact-Rated Shingles: For enhanced protection against wind-blown debris, impact-rated shingles like CertainTeed Landmark IR provide extra durability and may qualify for insurance discounts.
Cool Roof Shingles: Reflective granule technology reduces heat absorption, lowering attic temperatures and cooling costs. Particularly valuable in Hawaii's sunny climate.
For maximum longevity and salt air resistance, metal roofing is an excellent re-roofing choice:
Standing Seam: Premium standing seam systems like the Custom-Bilt Metals TITAN SL-1750 offer 40-70 year lifespans with concealed fasteners and Kynar 500 finishes. Ideal for modern homes and coastal properties.
Aluminum Interlock: Extremely popular in Hawaii, aluminum interlock systems provide exceptional corrosion resistance and wind performance with traditional shingle, shake, or tile appearances.
Metal Shingles: Metal panels that mimic the appearance of traditional shingles provide metal durability with a familiar look.
For homeowners wanting the classic Hawaii tile look with exceptional longevity:
Concrete Tile: Durable and versatile, available in flat, low-profile, and high-profile styles.
Clay Tile: Traditional barrel and S-tiles provide distinctive appearance with 50+ year lifespans.
Synthetic Tile: Lightweight alternatives that provide tile appearance without the structural requirements.
For homes with flat or low-slope roof sections:
TPO Membrane: Energy-efficient single-ply membrane ideal for low-slope applications.
Modified Bitumen: Reliable protection for lanais, carports, and additions.
Silicone Coating: For existing flat roofs in serviceable condition, coating systems can extend life significantly.
Hawaii's humidity and occasional roof leaks create conditions that promote wood rot. Addressing deck damage is essential for a successful re-roof:
Installing new roofing over damaged decking is like putting new paint over rotted wood. The problem remains and will eventually cause failure. Quality re-roofing addresses deck issues for lasting results.
Structural Integrity: Rotted decking can't hold fasteners properly. Shingles installed into soft, rotted wood will work loose and fail prematurely.
Flat Surface: New roofing needs a flat, solid surface for proper installation. Damaged decking creates uneven surfaces that affect appearance and performance.
Moisture Prevention: Damaged decking often indicates ongoing moisture problems. We identify and address the source of moisture, not just the resulting damage.
Plywood Replacement: Rotted sections of plywood sheathing are cut out and replaced with new material. We use appropriate thickness (typically 1/2" or 5/8") to match existing decking.
Shiplap Repair: For older homes with board decking, individual rotted boards are replaced. In some cases, overlaying with plywood provides a better substrate for modern roofing materials.
Fascia Replacement: Fascia boards at roof edges often rot from water exposure. We replace damaged fascia with pressure-treated or composite materials for improved durability.
Rafter Repair: If rot has spread to rafters, sister boards or partial rafter replacement restores structural integrity.
Deck repair is typically an additional cost beyond the base re-roofing price:
Sheathing Replacement: $40-60 per 4x8 sheet installed, plus tax.
Fascia and Rafter Repair: $16-20 per linear foot, including materials and labor to match existing.
Additional Layer Removal: If multiple roofing layers exist, additional demo costs approximately $100 per square (100 sq ft) plus tax.
Discovery During Tear-Off: Some deck damage isn't visible until old roofing is removed. We identify obvious damage during inspection, but additional repairs may be needed once tear-off reveals the full picture.

We serve residential re-roofing needs across the entire island:
Mililani and Mililani Mauka: Central Oahu homes face direct storm impact and consistent trade wind exposure. Many Mililani homes are now 30-40 years old, making them prime candidates for re-roofing with modern, high-wind rated materials.
Ewa Beach and Kapolei: West Oahu's intense sun accelerates roofing material deterioration. We recommend high-reflectivity materials for west side re-roofing projects to reduce cooling costs and extend roof life.
Pearl City and Waipahu: Established neighborhoods with diverse housing stock include many homes needing re-roofing. We assess each property's specific needs and recommend appropriate materials.
North Shore (Haleiwa, Kahuku, Laie): Severe coastal exposure requires premium corrosion-resistant materials. Metal roofing and aluminum flashings are particularly appropriate for North Shore re-roofing.
Kaneohe and Kailua: Heavy Windward rainfall means waterproofing integrity is critical. We emphasize quality underlayment and proper flashing for Kaneohe and Kailua re-roofing projects.
Waianae Coast: Extreme sun exposure plus salt air demands materials that handle both UV and corrosion. We specify appropriately for Waianae conditions.
Honolulu and Hawaii Kai: Varied microclimates across Honolulu require location-appropriate material selection. Coastal Hawaii Kai needs salt-resistant materials; inland areas have more flexibility.
If your roof has storm damage, insurance may cover significant portions of your re-roofing cost:
Storm Damage Claims: Wind damage, debris impacts, and water damage from storms are typically covered by homeowners insurance. If your aging roof was damaged by a storm, you may have a valid claim.
Full Replacement: When storm damage is widespread, insurance often covers full roof replacement rather than repairs. The age of your roof affects claim value, but even older roofs can qualify for substantial coverage.
Code Upgrades: If your policy includes "code upgrade" coverage, insurance may pay for improvements required to meet current building codes during replacement.
Matching Requirements: If damaged materials can't be matched, some policies require payment for additional replacement to maintain uniform appearance.
Our Documentation: We thoroughly document storm damage to support insurance claims. Proper documentation often results in larger approved claims than homeowners would receive documenting damage themselves.
We work with all major insurance carriers serving Oahu homeowners:
State Farm. Allstate. FICOH (First Insurance Company of Hawaii). Island Insurance. DTRIC. And all other Hawaii homeowners insurance providers.
Each insurance company has different claim processes and coverage details. Our experience with these carriers helps ensure your claim is documented properly and processed efficiently.
We're not a roofing contractor. We're your local advocate who ensures you get the best outcome for your re-roofing project:
Free Inspections: No obligation inspections for homeowners considering re-roofing. We assess your roof's condition, identify any insurance claim potential, and provide honest recommendations.
Material Expertise: We understand the full range of roofing options and can objectively recommend what's best for your specific situation. No pushing one manufacturer's products because that's what we stock.
Certified Contractor Network: Every contractor we work with is licensed, insured, and holds manufacturer certifications. This means proper installation and access to the strongest available warranties.
Independence: We're not tied to any single roofing company. When you call a roofer directly, they sell their services. We match your project with the best contractor and materials for your needs.
Insurance Navigation: We know how to document damage for insurance claims and work with adjusters to ensure fair claim valuation. Many homeowners leave money on the table by not properly documenting claimable damage.
Competitive Pricing: We help you get competitive bids from qualified contractors. Multiple bids ensure fair pricing without sacrificing quality.
Why should I use Oahu Roof Support instead of calling a roofer directly?
When you call a roofing company directly, they send a salesman who wants to sell their products and services. I independently assess your situation, help you understand your options, and connect you with certified contractors who can offer premium warranties. I also identify insurance claim opportunities that roofing salesmen might miss or not prioritize.
Do I pay more by going through Oahu Roof Support?
No. I help you get competitive bids from qualified contractors. You're getting access to certified installers and premium warranty coverage without paying more. The value is in proper material selection, quality installation, and maximum insurance recovery, not added cost.
How much does residential re-roofing cost in Hawaii?
Re-roofing costs vary based on roof size, material, and deck condition. Architectural shingle re-roofing typically runs $12,000 to $25,000 for average Hawaii homes. Metal roofing ranges from $20,000 to $50,000+. Tile re-roofing (with underlayment replacement) runs $25,000 to $60,000+. We provide detailed quotes based on your specific roof.
How long does re-roofing take?
Most residential shingle re-roofing projects are completed in 2-4 days. Metal roofing may take 4-7 days. Tile projects take 1-2 weeks or more. Weather, deck repair extent, and project complexity affect timeline.
Will my insurance cover re-roofing?
If your roof has storm damage, yes. Insurance covers damage from wind, debris, and related water intrusion. Even older roofs with storm damage can qualify for substantial claim payments. We document damage thoroughly to support your claim.
Should I repair or re-roof?
It depends on your roof's overall condition, the extent of damage, and remaining useful life. If your roof is under 15 years old with limited damage, repairs may make sense. If your roof is older, has widespread problems, or requires frequent repairs, re-roofing is usually the better investment. We help you evaluate the decision honestly.
What's included in the re-roofing price?
A complete re-roofing quote should include tear-off and disposal, underlayment, roofing material, flashings, pipe jacks, ridge caps, and cleanup. Deck repair is typically additional, priced as discovered. We ensure quotes are comprehensive so you're not surprised by add-on charges.
How much deck damage should I expect?
It varies. Some roofs have no deck damage. Others have significant rot, especially around leaks, valleys, and eaves. We identify visible damage during inspection, but additional damage often appears during tear-off. Budget 10-20% above base re-roofing cost for potential deck repairs unless inspection indicates otherwise.
Can I stay in my home during re-roofing?
Yes. Re-roofing is exterior work that doesn't require you to vacate. However, expect noise during working hours and some disruption. We protect landscaping and clean up daily. Most homeowners find the inconvenience minimal.
What warranties come with re-roofing?
Through our certified contractors, shingle re-roofing qualifies for 50-year material warranties and 25-year workmanship warranties backed by CertainTeed or GAF. Metal roofing carries 30-35 year finish warranties. Our contractors provide minimum 7-year workmanship warranties on all projects.
How do I know if re-roofing was done correctly?
Proper installation follows manufacturer specifications and building codes. Our contractors document their work for warranty purposes. We can provide oversight during installation for added assurance. Building department inspections verify code compliance when required.
What if I'm not happy with the contractor's work?
Because I'm independent, I have real accountability. If a contractor in my network does poor work, I address it and find resolution. My reputation depends on connecting homeowners with contractors who deliver quality re-roofing work.
