Understanding Your Roof Replacement Options
Roof Overlay vs. Roof Tear-Off (and How It Affects Roof Replacement Costs)
There are two primary methods of roof replacement: roof overlay and roof tear-off. Each approach has advantages depending on your specific situation.
Roof Overlay (Re-Roofing)
Roof overlay involves nailing new shingles over existing ones, which is less labor-intensive and faster. This installation method works only when:
You have just one layer of existing shingles
The roof deck underneath is solid with no water damage
Existing shingles lie relatively flat
Local building codes permit overlay
Overlays cost less initially because they skip tear-off and disposal. However, they hide potential problems underneath, add excessive weight to your structure, and typically void premium manufacturer warranties.
Most quality roofing contractors recommend against overlays for long-term performance.
Roof Tear-Off (Complete Replacement)
Roof tear-off requires removing the old roof down to the sheathing, allowing for inspection and repair of any underlying damage. This is the gold standard approach because:
Reveals hidden water damage, rot, or structural issues
Allows proper installation of modern ice and water shield protection
Ensures new shingles lie flat for maximum lifespan
Qualifies for best manufacturer warranties including workmanship warranty coverage
Removes excessive weight from old layers
We strip away old shingles, remove worn valley flashing and metal flashing, pull out thousands of roofing nails, and inspect every inch of your roof deck. Any damaged plywood sheathing gets replaced. Then we build your new roof correctly from a solid foundation.
A full replacement is generally more expensive than a partial replacement due to the increased labor and material costs involved. But it’s the right choice for Long-Island homes facing decades of nor’easters, heavy snow, and summer heat.
Signs You Need a Full Roof Replacement
When Repair Isn't Enough
Most asphalt shingle manufacturers offer warranties ranging from 20–30 years, while some premium options boast 50-year or even ‘lifetime’ warranties. But even within warranty periods, severe damage or age-related deterioration can make replacement more cost-effective than ongoing repair.
Look for these warning signs:
Age-Related Deterioration
Shingles are 20+ years old (nearing the end of typical lifespan)
Dark granules on laminated asphalt shingles absorb the sun’s radiation and push heat into the building, causing accelerated aging
Widespread curling, cracking, or brittleness across the entire roof
Multiple areas showing wear simultaneously
Storm & Weather Damage
Missing shingles after high winds or severe storms
Hail damage creating dimples or exposing granules
Ice dams causing water damage to roof deck and sheathing
Wind storm lifting or tearing existing shingles
Water Infiltration Issues
Active roof leaks in multiple locations
Water stains on ceilings or walls indicating ongoing water damage
Sagging roof deck from moisture saturation
Mold or rot in attic spaces from chronic leaks
Structural Concerns
Excessive weight from multiple layers of old shingles
Plywood sheathing or oriented strand board deterioration
Damaged or inadequate roof deck support
Falling objects damage that compromised structural integrity
Inspecting the current roof helps determine if repair or full replacement is necessary. A contractor should conduct a professional inspection of the roof before providing an itemized estimate. We provide honest assessments—if repair makes sense, we’ll tell you. If full replacement is the better investment, we’ll explain why.
Warranties & Long-Term Protection
Understanding Your Coverage
A manufacturer’s warranty covers defects in the roofing materials themselves, while a workmanship warranty covers the quality of the installation. You need both for complete protection.
Manufacturer Material Warranties:
Standard: 20-30 years against manufacturing defects
Premium: 50-year or “lifetime” limited warranties
Covers defective shingles only, not installation issues
May be prorated after certain years
Workmanship Warranty:
Covers installation quality and labor
Ranges from 1-10 years with most contractors
County Roofing Systems: 25-year workmanship warranty on most projects
Protects against leaks from improper installation
Enhanced System Warranties: Some manufacturers offer more expensive ‘total coverage’ warranties that cover the cost of new shingles and labor to reroof if the roof fails within a set timeframe. These require:
Certified contractor installation (GAF Master Elite, etc.)
Using all components from same manufacturer
Proper ventilation and attic conditions
Regular maintenance
Be sure to read and understand both warranties thoroughly, paying attention to what’s covered, what’s excluded, and any requirements for maintaining coverage.
Warranty Transferability: If you’re buying a house with a new roof, ask for the name of the manufacturer, notify the company of the change in ownership, and find out if the warranty transfers to you. Many warranties transfer with proper notification.
What Voids Warranties: Knowing how long warranties last and if anything would void them, such as pressure washing or inadequate attic ventilation, will help you make an informed decision. Common warranty-voiding issues:
Improper ventilation
Pressure washing shingles
Walking on roof excessively
Adding solar panels without proper integration
DIY repairs or modifications
Post-Replacement: Protecting Your Investment
Maintenance for Maximum Lifespan
Regular maintenance is key to ensuring the longevity of your new roof after replacement.
Annual Inspections:
Check for loose, damaged, or missing shingles
Inspect flashing around chimneys and penetrations
Clean gutters to prevent water backup
Look for moss or algae growth
Verify proper attic ventilation
Regular inspections catch small problems before they become expensive roof leaks.
Storm Damage Checks: After severe weather (high winds, hail, heavy snow):
Inspect for visible damage from surrounding area
Check for lifted or torn shingles
Look for dented vents or damaged flashing
Document damage for insurance claims if needed
Preventive Care:
Keep gutters clean to prevent ice dams
Trim overhanging tree branches
Remove debris that accumulates in valleys
Address small issues immediately to prevent leaks
Maintain proper attic ventilation and insulation
What NOT to Do:
Don’t pressure wash asphalt shingles (voids warranty, damages granules)
Don’t walk on roof unnecessarily
Don’t let moss or algae spread unchecked
Don’t ignore small leaks hoping they’ll stop
Proper ventilation is important during roof replacement to prevent moisture buildup and ensure longevity. We ensure adequate ridge vent and soffit ventilation on every project.

County Roofing replaced my aging roof and all of the gutters. Keith was truly professional, performing the estimate, supervising the work, and keeping me informed at every step. The results were beautiful. I would not hesitate to recommend County Roofing Systems to anyone.
Our roof was a bit of a tricky project, but Keith’s crew handled every nuance flawlessly—right down to protecting the gutters and surrounding landscaping. The workmanship is top-tier; you can see and feel the quality in every shingle. Equally impressive, Keith was completely transparent about costs and timelines, and his quote was the most competitive we received by a mile.
I had County Roofing Systems install new vinyl siding and gutters and leaders. Keith was very professional as well as personable and really knew his craft. Keith was on site the entire time with his crew. The house came out perfect. Just want to say thanks to Keith and I would give 5 stars plus! Thanks again Keith for all your good work.
Had a fantastic experience with County Roofing! Keith was extremely thorough. He walked through every detail, explained all the color options, and offered thoughtful recommendations that made a big difference. His crew did an outstanding job, and our new roof looks absolutely amazing.
Highly recommend County Roofing to anyone looking for a reliable, skilled roofing team!
What impressed me the most was the mix of professionalism and friendliness. Our Firestone flat roofing New York job was complex, but everything was explained clearly and handled carefully. The work speaks for itself, and I wouldn’t hesitate to recommend them to anyone.
Recently had a new roof done by County Roofing, and am so thankful for having met Keith. He is fair with the price, knowledgeable about his work, patient, responsive and professional. It really was a pleasure, and I will definitely be recommending Keith and his crew to anyone I know looking to do roof work.
