What is the Average Cost for Shingle Roof Replacement?
On average, the cost for a shingle roof replacement in New Jersey in 2025 ranges from $8,000 to $15,000. This depends on the size of your home, shingle material, and complexity of the job. Basic asphalt shingles are more affordable, while architectural or premium shingles cost more but last longer. Labor and removal of the old roof also factor into the total cost. Remember that cheaper isn’t always better. Cutting corners now may lead to expensive problems in the future.

5 Mistakes That Will Make Shingle Roof Replacement More Expensive
Now that you know the typical cost of a roof replacement in New Jersey, let’s discuss the mistakes that may make your replacement more expensive.
1. Waiting Too Long to Replace Your Roof
One of the most expensive mistakes homeowners make is delaying a necessary roof replacement. Minor issues—like curled shingles, small leaks, or granule loss—can quickly escalate into major problems such as rot, mold, or structural damage if left untreated. The longer you wait, the more extensive (and costly) the repairs become. Acting early can save thousands in long-term repair and replacement costs.
2. Choosing the Cheapest Contractor
Everyone wants to save money, but selecting the cheapest contractor often ends up being more expensive in the long run. Lower bids can mean lower quality, meaning subpar materials, inexperienced labor, or skipping key installation steps. A poorly installed roof won’t last, and fixing mistakes from a bad install could cost you more than the original replacement would have.
3. Not Getting a Written Estimate
Verbal agreements are risky. Without a written estimate, there’s no way to track pricing, hold the contractor accountable, or understand what you’re really paying for. A detailed written quote should outline the scope of work, materials used, labor costs, and any additional fees. This protects both you and the contractor and ensures the job goes as expected and without surprise expenses.
4. Overlooking Ventilation and Insulation
Proper attic ventilation and insulation are essential to the performance of your new roof. Without adequate airflow, heat and moisture can build up in your attic, leading to mold growth, shingle damage, and reduced energy efficiency. During a shingle roof replacement, it’s the perfect time to evaluate and improve your home’s ventilation and insulation for better comfort and long-term durability.
5. Failing to Check Warranty Coverage
Many homeowners assume their new roof is automatically covered by a long-term warranty—but that’s not always the case. Some warranties have strict terms that must be followed, including using certified contractors or registering the warranty within a certain timeframe. If you skip these steps or use a non-approved installer, you could lose coverage and be stuck paying for future repairs yourself.
Shingle Roof Replacement FAQs
How long does a shingle roof replacement take?
A standard replacement usually takes 1 to 3 days, depending on the size and complexity of the roof and weather conditions.
Will my homeowner’s insurance cover a shingle roof replacement?
It depends. If the damage is due to a covered event, such as hail or wind, your insurance may cover part or all of the cost. Wear and tear from age typically isn’t covered.
How do I know if I need a full replacement or just a repair?
A professional inspection is the best way to determine this. Extensive damage, multiple leaks, or an aging roof (15–25 years old) usually mean it’s time for a replacement.
