Shingle Roofing 101: Installation, Repair & Cost Explained

When a storm rolls through and the drip-drip-drip starts, you know how fast a small roof problem can turn into a major headache. Whether you’re a homeowner or a business manager, shingle roofing is often your building’s first line of defense. At STL Roofing, we understand the urgency that comes when your roof is at risk—especially in emergency roofing situations.

We’ve installed, repaired, and replaced shingle roofs in every season. Our certified installers know the ins and outs, and we’re here to break it all down for you. No jargon. No runaround. Just the straight facts you need to protect your property.

Types of Shingles: Asphalt, Architectural, Designer 🏠

Shingle roofing is like your building’s outerwear—simple or stylish, but always protective. Here are the main types you’ll see:

Asphalt Shingles

These are the blue jeans of roofing—classic, affordable, and everywhere. Asphalt shingles are made from a fiberglass mat and coated with asphalt and mineral granules. They’re budget-friendly and come in a wide range of colors.

Pros:

• Cost-effective
• Easy to repair
• Widely available

Cons:

• Shorter lifespan (usually 15–25 years)
• More prone to wind uplift

Architectural Shingles

Think of these as the tailored suit of roofing. Thicker and layered, architectural shingles give your roof extra dimension and durability. They’re a step up in both looks and performance.

Pros:

• Longer lifespan (20–30 years)
• Better weather resistance
• Visually appealing

Cons:

• Higher cost than basic asphalt
• Heavier—may need added support for older structures

Designer (Luxury) Shingles

Want your home or business to stand out? Designer shingles mimic the look of slate or wood shakes but use modern materials. They’re the tuxedo of the roofing world.

Pros:

• Highest curb appeal
• Superior durability
• Wide color and pattern range

Cons:

• Highest price point
• Installation takes longer

The Shingle Installation Process: Step by Step

Shingle roof installation is both an art and a science. It looks simple from the street, but every layer matters.

1. Inspection & Prep: Our team inspects the deck (the wood beneath) and repairs any rot, sagging, or leaks.
2. Tear-Off: Remove old shingles, nails, and underlayment. Clean the surface.
3. Underlayment: Install water- and ice-shield barriers, especially along eaves and valleys.
4. Starter Strips: Lay down starter shingles along edges to prevent wind uplift.
5. Shingle Laying: Work up the roof with staggered rows. Nail placement and overlap are key.
6. Flashing & Vents: Install metal flashing around chimneys, vents, and valleys. This prevents leaks.
7. Ridge Caps: Finish the peak with special ridge shingles for a clean, dry seal.
8. Cleanup: Remove debris, run a magnet for stray nails, and inspect for quality.

Best Practices for Shingle Roof Repair

Shingle roofs can be patched, but only if you catch problems early. Here’s what pros look for:

• Missing or cracked shingles: These let water in—fast.
• Curled edges: Signal age or heat damage.
• Granule loss: Check your gutters. More granules means less shingle protection.
• Damaged flashing: Rust or gaps around vents and chimneys are leak magnets.

Repair tips:

• Replace only with matching shingles.
• Always check underlayment for hidden rot.
• Use roofing nails—not staples—for repairs.
• Apply sealant under the shingle tab for wind resistance.

For larger areas, it’s often safer and more cost-effective to call a pro. Shingle repairs require a keen eye and steady hand—especially at height.

Typical Costs and Warranties: What to Expect 💸

Shingle roofing costs can feel like a maze. Here’s what goes into the price:

• Type of shingle (asphalt, architectural, designer)
• Roof size and pitch
• Tear-off vs. overlay (removing old shingles takes more time and labor)
• Decking or structural repairs (if needed)
• Local labor rates and permits

Estimated ranges:

• Asphalt: $3–$5 per square foot installed
• Architectural: $5–$8 per square foot installed
• Designer: $8–$14+ per square foot installed

Warranties:

• Most manufacturers offer 20–30 years on materials.
• Workmanship warranties (from installers like STL Roofing) typically cover 2–10 years, depending on the job.
• Always read the fine print—some warranties are voided by improper installation or poor attic ventilation.

Tip: Go for the longest manufacturer warranty that matches your climate and roof type, but don’t overlook the installer’s workmanship guarantee.

Signs It’s Time for Replacement

How do you know when repairs just won’t cut it? Look for these warning signs:

• Bald spots: Shingles missing most of their granules.
• Widespread curling or cracking: Not just a few, but many.
• Frequent leaks: Especially after storms.
• Sagging roof deck: The “dip” is never good.
• Moss or algae growth: Often means trapped moisture.

Age matters too. Most asphalt shingle roofs need replacing after 20–25 years, even if they look okay from the ground.

Tips to Maximize Shingle Roof Lifespan

Every roof gets old, but you can stretch those years:

• Keep gutters clear: Water backup wrecks shingles.
• Trim overhanging branches: Stops shade, debris, and critter damage.
• Annual inspections: Look for small problems before they grow. STL Roofing offers seasonal checkups.
• Attic ventilation: Prevents heat and moisture buildup, which can void warranties.
• Fast leak repairs: Water damage spreads fast—don’t wait.

Choosing the Right Warranty for Your Roof

Not all warranties are created equal. Here’s how to choose:

• Manufacturer warranty: Covers the shingles themselves. Longer is better, but check what’s excluded.
• Workmanship warranty: Covers the installation. If your installer cuts corners, this is your backup.
• Transferability: If you sell your property, can the next owner keep the warranty?

Ask for both—and get it in writing.

Shingle Roofing for Homes and Businesses

Shingle roofs aren’t just for suburban homes. Many commercial buildings use them too, especially small offices, retail, or apartments. STL Roofing installs and repairs shingle roofs for both, using certified crews for each property type.

Residential:

• Asphalt and architectural shingles are most common.
• Curb appeal is key.

Commercial:

• Heavier-duty shingles or specialty products.
• Focus on durability and energy efficiency.

Our emergency roofing teams are ready for both. Whether it’s a midnight leak or a planned replacement, STL Roofing delivers.

Quick Safety Checklist Before You Touch the Roof

Before you—or anyone—gets on a roof, check these:

• Wear slip-resistant shoes
• Use a properly secured ladder
• Never work alone
• Watch for overhead power lines
• Avoid steep or wet roofs

OSHA guidelines recommend harnesses for any roof work above 6 feet. Safety isn’t optional, it’s essential.

DIY vs. Call a Pro

Some repairs look simple, but shingle roofs can be tricky. DIY works for:

• Replacing a single shingle (if you’re comfortable at height)
• Clearing minor gutter blockages

When to call STL Roofing:

• Multiple damaged shingles
• Leaks in the attic or ceiling
• Flashing or vent repairs
• Storm or wind damage

Remember: Falls are the #1 cause of construction injuries. If you’re not sure, leave it to certified installers.

What Pros Do On Arrival

When STL Roofing arrives, here’s what you can expect:

• Full inspection—rooftop and attic
• Moisture scan for hidden leaks
• Assessment of underlayment and flashing
• Photo documentation (before/after images)
• Detailed repair or replacement plan

We bring the right tools, follow code, and keep you updated every step.

Prevention & Maintenance

A little attention goes a long way:

• Schedule annual roof inspections—spring and fall are ideal.
• After storms, check for missing shingles or clogged downspouts.
• Invest in Downspout Installation near you to direct water away from the foundation.
• Clean gutters regularly or use gutter guards.

The National Roofing Contractors Association recommends twice-yearly inspections (see NRCA guidelines).

Costs & Time Factors

Every roof is different. Here’s what affects project duration and price:

• Roof complexity: More valleys, dormers, or skylights = more time.
• Weather: Rain or snow can delay work.
• Material availability: Specialty shingles may need to be ordered.

Typical timeframes:

• Simple repair: 1–2 hours
• Full replacement: 1–3 days (weather permitting)

Unexpected structural repair, decking, or storm damage restoration may add time. Our crews work efficiently, but never cut corners.

Local/Seasonal Considerations

If you live where temperatures swing or storms hit hard, shingle choice matters. In snowy areas, proper roof ventilation and ice shields are critical. In hot, sunny climates, opt for lighter-colored shingles to reflect heat.

STL Roofing’s teams are trained for all weather. We follow local building codes and manufacturer specs for every install.
