Do I Need a New Roof? A Straightforward Guide for Phoenix Homeowners

If you’re wondering whether you need a new roof, you’re probably already seeing signs that something isn’t right.

Maybe you’ve had a leak. Maybe shingles are cracking. Maybe a roofer suggested replacement and you’re not sure if it’s necessary.

Here’s a clear, no-pressure guide to help you understand when a new roof makes sense — and what to expect if it does.

How Long Does a Roof Last in Phoenix?

Roof lifespan depends on material, installation quality, and sun exposure. In Arizona’s climate, heat is the biggest factor.

Typical lifespan ranges:

• Asphalt shingle roofs: 15–25 years
• Tile roofs: 25–50+ years (underlayment often fails before tiles)
• Foam roofs: 15–25 years with proper recoating
• Metal roofs: 30–50+ years

In Phoenix, extreme UV exposure shortens lifespan compared to cooler climates. Even if shingles look intact, the underlayment may be deteriorating underneath.

If your roof is over 20 years old and hasn’t been replaced, it’s worth having it inspected.

Signs You May Need a New Roof

Not every issue requires full replacement. But these signs often indicate it’s time:

• Repeated leaks in different areas
• Widespread cracked or curling shingles
• Soft spots when walking on the roof
• Water stains on ceilings or walls
• Underlayment deterioration (common with tile roofs)
• Major storm or wind damage

If repairs are becoming frequent, replacement may actually cost less over time.

What’s Included in a Roof Replacement?

Many homeowners aren’t sure what “new roof” actually means.

A proper roof replacement typically includes:

1. Removal of old roofing materials
2. Inspection of roof decking
3. Replacement of damaged plywood if needed
4. Installation of new underlayment
5. New flashing around vents and penetrations
6. Installation of new roofing material (shingle, tile, foam, or metal)
7. Cleanup and magnetic nail sweep

If a proposal skips steps like decking inspection or flashing replacement, that’s a red flag.

A roof system is more than just the visible surface.

How Long Does It Take to Replace a Roof?

For most residential homes in Phoenix:

• Shingle roof replacement: 1–2 days
• Tile roof replacement (with underlayment): 2–5 days
• Foam Roofing: 2–4 days depending on size

Weather, complexity, and repairs can extend timelines.

You don’t have to move out during replacement. There will be noise, but professional crews work efficiently and clean thoroughly each day.

How Much Does a New Roof Cost?

Roof replacement cost depends on:

• Size of the home
• Roof pitch and complexity
• Material selected
• Condition of decking
• Type of underlayment

In Phoenix, most residential roof replacements fall within a wide range depending on these factors.

Rather than guessing from online averages, the most accurate way to understand cost is through an inspection. That allows the roofer to assess underlayment condition, ventilation, and structural concerns.

If someone gives you a price without inspecting the roof, that’s not a reliable estimate.

What Warranty Comes with a New Roof?

There are typically two types of warranties:

Manufacturer Warranty

Covers defects in materials.

Workmanship Warranty

Covers installation quality.

Both matter.

A long manufacturer warranty doesn’t help if installation was done incorrectly. Proper flashing, underlayment installation, and ventilation are critical to performance.

Always ask:

• What does the workmanship warranty cover?
• Is it transferable?
• What voids it?

Repair or Replace?

One of the most common concerns homeowners have is being pushed into replacement when a repair would work.

A good roofer should explain:

• What is failing
• Whether repair is viable
• How long a repair would realistically last
• The cost difference over time

Sometimes a repair buys you years. Sometimes it only delays the inevitable.

Clarity matters more than pressure.

When It Makes Sense to Replace

A new roof is usually the right decision when:

• Repairs are stacking up
• Underlayment has reached the end of its life
• Storm damage affects large sections
• You’re preparing to sell your home
• Energy efficiency is a concern

A properly installed roof protects your home for decades. It’s not just an expense — it’s structural protection.
