7 Roofing Questions Homeowners Always Ask (And the Answers They Actually Need)

Intro (Day 1) 

When it comes to roofing, homeowners have plenty of questions—especially when leaks appear, shingles go missing, or it’s time for a full replacement. Over the next 7 days, we’ll break down the most common roofing questions and give you straight, honest answers. Whether you’re patching up storm damage or planning a future upgrade, this series will give you the info you need to make smart roofing decisions.

Day 1: How do I know if my roof needs to be replaced or just repaired?

It’s the most common question—and a valid one. Look for these signs:

• Widespread shingle damage

• Leaks in multiple spots

• Roof is 15-25+ years old

• Sagging or rotting areas

If it’s a small leak or isolated damage, a repair might be enough. But if your roof is aging and repairs are stacking up, replacement may be the smarter investment.

Day 2: How long does a roof typically last? 

Most roofs last 20 to 30 years, depending on:

• Material used (asphalt, metal, slate, etc.)

• Weather exposure

• How well it’s been maintained

Asphalt shingles (the most common material) usually last 20-25 years. Metal and slate roofs can go 50 years or more with proper care.

Day 3: What does a new roof actually cost? 

Roof pricing varies based on size, materials, and labor—but expect:

• Asphalt shingles: $5,000–$12,000

• Metal roofing: $10,000–$20,000+

• Luxury materials (slate, tile): $25,000+

Keep in mind: a cheap roof now can mean expensive problems later. A fair price from a reputable company will always be worth it.

Day 4: What kind of roofing material should I choose?

Each type has pros and cons:

• Asphalt shingles: Affordable, reliable, versatile.

• Metal roofing: Durable, energy-efficient, long-lasting.

• Slate/tile: Elegant, very durable, but heavy and expensive.

• Synthetic options: Mimic high-end looks with better flexibility.

We’ll help you pick what fits your budget, style, and long-term goals.

Day 5: How long does a roof replacement take? 

Most residential roof replacements take 1–3 days, depending on:

• Roof size & complexity

• Weather conditions

• Material type

Day 6: Can I just install new shingles over old ones? 

Short answer: It’s possible—but not always a good idea.

While a second layer may save on removal costs, it can:

• Hide existing damage

• Add extra weight

• Shorten lifespan of the new roof

In most cases, a full tear-off is the best move for long-term performance.

Day 7: Is a roof warranty really worth it? 

Absolutely. A roof warranty protects your investment, especially when it covers:

• Workmanship

• Materials

• Future repairs or issues

At NJ Roofing Maintenance, we even offer roof repair warranty plans you can subscribe to—monthly or annually. It’s peace of mind, on your terms.
