The Top 11 Roofing Questions Answered
As a homeowner, it’s essential to stay vigilant about your roof’s condition. It serves as your home’s first line of defense against the elements in Savannah, including wind, rain, and hail. However, whether you have a metal roof or a shingle roof, depending on its age, you will eventually have to replace it.
Below are the top roofing questions we often get at Roofing Experts regarding new roofs and roof replacements in general!
1. What are the signs that it’s time for a new roof?
Quick Signs of New Roof Need:
- Missing or damaged shingles
- Roofs that are 20+
- Roof leaks
One of the primary signs that you may need a new asphalt shingle roof is visible wear and tear, such as missing shingles or cracked or curling shingles. If left unaddressed, these small issues can compromise the integrity of your roof, leading to potential roof leaks and further damage. Even a small section of damaged shingles can allow water to seep in, which may result in costly interior repairs down the line, which means you need a new roof.
Replacing your asphalt shingle roof is often determined by the age of your current roofing system. Most asphalt shingle roofs have a life expectancy of 20 to 25 years, depending on the materials’ quality and the local climate (in Savannah, it can be sooner because of hurricanes). If your roof is nearing or has exceeded this age range, even if it appears in decent condition from the ground, it might be time to start planning for a replacement.
Additionally, look for signs of granules collecting in your gutters or around your home’s foundation, as this indicates that your shingles are deteriorating. Taking action early can save you from more extensive and expensive repairs in the future, so keeping an eye out for these signs is vital to protecting your home investment.
2. How much does a new roof cost based on the roofing material?
Here is the quick answer to average roofing costs based on a standard-sized roof of 1700-2200 square feet in the Savannah area!
🏠 3-Tab Asphalt Shingles
- Cost per sq. ft. (installed): $3 – $5
- Average roof cost (1,700–2,200 sq. ft.): $5,100 – $11,000
- Lifespan: 15–20 years
- Notes: Basic, budget-friendly option; thinner and lighter than architectural shingles. Only rated for 90 MPH winds which is less than ideal for Savannah’s hurricanes.
🏠 Architectural (Dimensional) Shingles
- Cost per sq. ft. (installed): $4 – $7
- Average roof cost: $6,800 – $15,400
- Lifespan: 25–30 years
- Notes: Thicker, more durable, better curb appeal and wind resistance. 130 MPH wind rating is ideal for coastal climates like that in Savannah due to hurricane winds
🔩 Standing Seam Metal Roof
- Cost per sq ft (installed): $9 – $14
- Total cost: $18,000 – $28,000
- Lifespan: 40–70 years
- Pros: Durable, energy-efficient, low maintenance, modern look
- Cons: Higher upfront cost
3. Can you install a new roof over an old one?
The short answer is YES you can install a new roof over an old one, the modern answer is also “NO” you shouldn’t do it! In the past, roofers used to do a Re-roof where they would just install new shingles on the old one. However, this is no longer common practice and not recommended by professional roofing contractors!
Here is why a roof over was done and why we recommend you don’t!
- ✅ Cost Savings
– No tear-off means lower labor and disposal costs. - ✅ Faster Installation
– Less work = shorter project timeline. - ⚠️ Not Always Allowed
– Building codes in some areas limit you to one overlay. - ⚠️ Weight Concerns
– Too much weight can stress your roof structure. - ❌ No Deck Inspection
– Skipping tear-off means you can’t check for rot or damage underneath. - ❌ Shorter Lifespan
– Roof-overs often don’t last as long as full replacements.
4. How many layers of shingles can be on a roof?
The maximum amount of layers of shingles on a roof is two, however, some states mandate a maximum of one. Like our previous answer to a reroof, we don’t recommend it. In the state of Georgia, reroofing (installing new shingles over existing ones) is possible under certain conditions. Still, it’s often discouraged and may not be permitted if the roof already has multiple layers or is damaged. Legally speaking, you can’t install new shingles over old damaged shingles, nor should you! Don’t fall for the “Cheaper” option for shingles.
5. What’s the best roofing material?
The BEST roofing material really depends on a few factors, including your budget, the size of your roof, how long you plan to stay, and HOA requirements. For the Roofing Experts of Savannah, we always say the best choices are either Asphalt Shingles or Standing Seam Metal roofing materials. If you plan to stay at your home for 20+ years, a metal roof will offer the most durability and curb appeal. However, if you are on a budget, dimensional asphalt shingles are a great idea!
Asphalt shingles are the best roofing material for most homeowners due to their affordability, versatility, and ease of installation. Available in various colors and styles, they suit nearly any home design while offering reliable protection against the elements. Architectural shingles, in particular, provide improved durability, wind resistance, and curb appeal compared to basic 3-tab options. They’re also relatively low-maintenance and come with warranties that often span 25–30 years, making them a wise long-term investment.
Standing seam metal roofs are a close second for their superior durability, energy efficiency, and sleek, modern look. Made from interlocking metal panels that resist leaks and harsh weather, they can last 40 to 70 years with minimal maintenance. Though more expensive up front, metal roofs often deliver savings over time thanks to reduced cooling costs and extended lifespan. Metal is a top-tier upgrade for homeowners seeking a high-performance roof on The Islands or Downtown Savannah.
6. What is the process of having a new roof installed?
The new roof installation process is standard when you work with reputable roofing contractors in your area. The process typically follows this flow:
- Setup a time for a free roofing consultation
- Pick out your roofing material, including the type of shingle, color, and style
- Go over the estimate and ratify the roofing contract, including warranty and labor terms
- Order shingles and roofing system including ridge vent, pipe collars, underlayment
- Remove the old roofing system down to your roof decking (plywood)
- Install a new roofing system complete with underlayment, shingles, flashing, drip edge, vents, and more
7. What’s the average cost of a new roof?
The average cost of new roof will vary based on the roofing material, where you live, and the size of your roof. Roofing costs are determined by square foot. According to Smart Roofing Pro, these are the national averages based on the roofing materials:
| Roofing Material | Total Cost Range |
|---|
| Asphalt Shingles | $8,000 – $17,000 |
| Galvanized Steel | $14,000 – $30,000 |
| Cedar Shakes | $14,000 – $32,000 |
| Concrete Tile | $15,000 – $40,000 |
| Aluminum | $16,000 – $34,000 |
| Slate Tiles | $19,000 – $52,000 |
| Clay Tiles | $22,000 – $50,000 |
| Copper | $42,000 – $80,00 |
8. How long does a roof last?
A well-maintained roof that doesn’t have storm damage should last a minimum of 20 years. However, this is all dependent on the roofing material itself. Here is a quick break down by the most popular roofing materials:
🟩 Metal Roof (Standing Seam or Ribbed Panels)
- Lifespan: 40–70 years
- Notes: Extremely durable, resists wind, fire, and corrosion. It can last longer with proper maintenance.
🟧 3-Tab Asphalt Shingles
- Lifespan: 15–20 years
- Notes: Most affordable option, but thinner and less resistant to wind and weather than architectural shingles.
🟨 Architectural (Dimensional) Shingles
- Lifespan: 25–30 years
- Notes: A thicker, layered design offers better durability, wind resistance, and a longer lifespan than a 3-tab.
🟫 Wood Cedar Shakes
- Lifespan: 25–40 years
- Notes: Beautiful and natural-looking, but requires regular maintenance. Vulnerable to moisture, mold, and insects if not properly cared for.
9. How many quotes should you get for a new roof?
We always recommend our clients get at least two quotes, but preferably three roofing quotes. This will help you compare not just the price but the quality of the warranty, the shingle type, and the durability. Remember, cheaper can mean more expensive in the long run because if a roof is installed incorrectly, you will have to fix it in a few years.
10. What warranties come with a roof replacement?
Roofing warranties vary based on the shingle manufacturer and their terms, and most companies offer a limited labor warranty that is dependent on each specific roofing contractor.
Manufacturer’s Warranty (Material Defects)
- Top Shingle Manufacturers include GAF, CertainTeed, Owens Corning
- Standard Coverage: 20–50 years, depending on the shingle type (three tabs vs. dimensional vs. premium).
- Covers: Defects in the shingle materials (e.g., premature cracking, blistering, or granule loss).
- Does NOT Cover: Improper installation or storm damage.
Workmanship Warranty (Installation)
- Provided By: The roofing contractor you work with.
- Typical Coverage: 1–10 years, sometimes longer.
- Covers: Issues caused by poor installation practices.
- Important: Only valid if the contractor stays in business (which is why you should use a long term company).
11. Will homeowners insurance pay for a new roof?
The answer to the homeowners insurance paying for a new roof is YES and NO.
Yes—but only if a covered event, like wind, hail, fire, or a fallen tree, causes the damage. Insurance will typically pay for repairs or replacement if the damage is sudden and accidental from a hurricane, lets say. However, insurance does not cover:
- Normal wear and tear
- Old age or neglect
- Improper installation or maintenance issues
Coverage can vary depending on your policy:
- Replacement cost coverage pays for a brand-new roof.
- Actual cash value coverage deducts for depreciation (you get less money).
To file a successful claim, you’ll usually need:
- Prompt inspection after damage
- Documentation (photos, reports)
- A licensed roofing contractor’s assessment
