Cost by Repair Type
Different roof problems have different price tags. Here is a detailed breakdown by repair type:
| Repair Type | Cost Range | What's Involved |
|---|---|---|
| Leak repair (single source) | $300 – $1,200 | Locate leak source, seal or replace damaged area |
| Shingle replacement (small area) | $300 – $600 | Remove damaged shingles, install matching replacements |
| Flashing repair | $400 – $1,000 | Replace or reseal flashing around chimneys, walls, vents |
| Chimney flashing replacement | $600 – $1,500 | Full chimney counter-flashing and step flashing |
| Vent pipe boot replacement | $200 – $500 | Replace rubber boot seal around plumbing vent |
| Valley repair | $500 – $1,500 | Reseal or replace valley flashing and surrounding shingles |
| Ridge cap replacement | $400 – $1,000 | Replace ridge cap shingles along roof peak |
| Storm damage repair | $500 – $4,000 | Emergency tarping + permanent repair of wind/hail damage |
| Flat roof repair (TPO/EPDM) | $400 – $2,000 | Patch membrane, reseal seams, address ponding |
| Skylight leak repair | $500 – $1,500 | Reseal or replace skylight flashing kit |
| Decking/sheathing repair | $50 – $100/sheet | Replace rotted plywood under roofing material |
Most homes need one or two of these repairs at a time. If you are facing three or more issues simultaneously on a roof over 20 years old, it may be time to consider a full replacement instead.
Cost by Damage Severity
Minor Damage: $300 – $800
A few missing shingles, one small leak, a cracked vent boot, or minor flashing separation. These are straightforward repairs that take a few hours and use standard materials.
Common causes: Normal aging, minor wind events, wear around penetrations.
Moderate Damage: $800 – $2,500
Multiple leak sources, a section of damaged shingles (10–15% of roof), chimney flashing failure, or valley deterioration. Requires more extensive work but does not justify full replacement.
Common causes: Storm damage, ice dams, deteriorating flashing on aging roofs.
Major Damage: $2,500 – $5,000+
Large areas of missing or destroyed roofing, structural damage from fallen trees, extensive water infiltration with deck rot, or damage covering 25–40% of the roof. At this level, get both repair and replacement quotes to compare.
Common causes: Severe storms, fallen trees, long-deferred maintenance, ice dam damage.
Common Roof Repairs in Essex County and What They Cost
Based on our project history, here are the repairs we perform most frequently in Essex County, along with typical costs:
Wind-Blown Shingle Replacement ($300–$800)
After nor'easters and thunderstorms, we regularly replace shingles blown off by high winds. For a small area (5–20 shingles), this is a quick, affordable fix. The key challenge is matching the color and style of existing shingles, especially on roofs over 10 years old where the color has weathered.
Chimney Flashing Leak Repair ($600–$1,500)
Chimneys are the most common source of roof leaks on Essex County homes. The flashing (metal seal between chimney and roof) deteriorates over time, especially on older homes in West Orange and Montclair. A proper repair involves removing old flashing, installing new step and counter-flashing, and sealing with high-quality roofing cement.
Ice Dam Damage Repair ($500–$2,000)
New Jersey winters cause ice dams, especially on older homes with poor attic insulation. Ice dams force water under shingles, damaging the underlayment and potentially the deck. Repair involves replacing damaged shingles and underlayment, and we recommend adding ice and water shield to prevent recurrence. Read our ice dam prevention guide to protect your home.
Flat Roof Membrane Repair ($400–$2,000)
Many Essex County homes — particularly multi-family properties in Newark and East Orange — have flat roof sections that use rubber (EPDM) or TPO membranes. Common repairs include patching punctures, resealing seams that have separated, and addressing ponding water issues.
Emergency Storm Tarping ($300–$800)
When a storm opens a hole in your roof, immediate tarping prevents interior water damage while you wait for permanent repair. R&E Roofing provides 24/7 emergency response across Essex County. Tarping is a temporary measure; permanent repair is scheduled and performed separately.
When Repair Isn't Enough
There comes a point when continued repairs cost more than they are worth. Consider replacement instead of repair when:
- 1.Your roof is over 20 years old and you are repairing it more than once a year.
- 2.Repair estimates exceed 40–50% of replacement cost. At that point, the math favors a new roof with a full warranty.
- 3.You have multiple active leaks in different areas, suggesting system-wide failure rather than isolated damage.
- 4.Shingles are curling, cracking, or losing granules across most of the roof, not just in one spot.
- 5.You are planning to sell within 5 years. A new roof adds more value than patching an old one.

Insurance Claims for Roof Repair in NJ
If storm damage caused your roof problem, your homeowners insurance may cover part or all of the repair cost. Here is what you need to know:
What Insurance Covers
Sudden and accidental damage: wind, hail, fallen trees, lightning, ice storms. Your policy's deductible ($500–$2,500 typically) applies before coverage kicks in.
What Insurance Does NOT Cover
Normal wear and tear, gradual deterioration, maintenance neglect, mold, or damage from pre-existing conditions. If your 25-year-old shingles just wore out, that is not a covered claim.

Frequently Asked Questions About Roof Repair Costs
How much does a roof leak repair cost in NJ?
A roof leak repair in New Jersey typically costs $300-$1,200 depending on the source and severity. Simple vent pipe boot replacements run $300-$500. Flashing repairs around chimneys cost $400-$900. Complex valley leaks or multiple leak sources can run $800-$1,500+.
How much does emergency roof repair cost?
Emergency roof repair in NJ costs $500-$2,500+ depending on the scope. Emergency tarping (temporary waterproofing) costs $300-$800. After-hours or weekend service may add 20-50% to standard rates. The permanent repair is then performed during normal hours at standard pricing.
Is it cheaper to repair or replace a roof?
Repairs are cheaper upfront ($300-$5,000) vs. replacement ($8,000-$25,000+), but it depends on your roof's condition. If your roof is under 15 years old with localized damage, repairs make financial sense. If it is over 20 with widespread issues, replacement is usually more cost-effective than ongoing repairs.
Does homeowners insurance cover roof repairs?
Insurance covers roof repair damage from sudden events (storms, hail, fallen trees) but not normal wear and maintenance. Document all storm damage with photos before calling your insurer. R&E Roofing provides detailed inspection reports and works with insurance adjusters to support your claim.
How much does it cost to replace missing shingles?
Replacing a small area of missing shingles (5-20 shingles) costs $300-$600 including materials and labor. Larger areas or hard-to-match older shingles may cost $500-$1,000+. If more than 25-30% of shingles need replacement, a full roof replacement is usually more economical.
How long does a roof repair last?
A properly done roof repair should last 5-15 years depending on the type of repair and overall roof condition. Flashing repairs and vent boot replacements are long-lasting fixes. Patching deteriorated shingles on an aging roof is more of a temporary measure. R&E Roofing warranties all repairs for 5 years.
Should I repair my roof before selling my house?
Yes, addressing known roof issues before listing is strongly recommended. Buyers' home inspections will flag roof problems, potentially reducing offers by more than the repair cost. A recent roof repair or replacement is a strong selling point that can increase your home's value.
How do I know if my roof needs repair?
Warning signs include: water stains on ceilings, missing or curled shingles visible from the ground, granules collecting in gutters, daylight visible through the attic roof, sagging areas, and higher-than-usual energy bills. If your roof is over 15 years old, schedule a professional inspection.
