Asphalt Shingle Roof Replacement FAQs

Roof repair makes sense when damage is isolated to a small area of shingles, a few cracked tabs or a minor flashing issue. A full roof replacement is typically the right call when:

• Your roof is 20+ years old and showing widespread wear
• You have granule loss across large sections (check your gutters for sandy looking debris)
• Multiple shingles are curling, cracking or buckling
• You've had repeated leaks in different locations
• There's soft decking or sagging visible from inside your attic

A professional inspection is the most reliable way to get a clear answer. LOA Roofing offers free inspections with no pressure. It's just honest, professional advice about what we see.

Watch for these red flags, both from the ground and inside your home:

• Curling or cupping shingles — Shingles that curl up at the edges or cup in the middle are losing their integrity.
• Bald spots — Areas where granules have worn away, leaving the dark asphalt exposed.
• Cracked or missing shingles — This can be especially problematic after wind events.
• Dark streaks or moss growth — Algae and moss retain moisture and accelerate deterioration.
• Daylight visible in the attic — It's a clear sign of gaps or damaged roof decking.
• Water stains on the ceilings or walls — Even small stains can indicate an active leak.

Pro tip from LOA: Don't wait for an active roof leak to get an inspection. By the time water shows up inside, structural damage to your decking or insulation may have already occurred. Timely roof leak repair significantly reduces the costs.

Late spring through early fall is generally ideal in Central Texas. Asphalt shingles seal most effectively in mild temperatures between 40°F and 85°F. That said, experienced roofing contractors can work year-round, and waiting for the "perfect season" isn't worth the risk if your roof is actively failing.

Scheduling in late summer or fall also makes sense if you want to protect your home after the storm season but before winter weather hits. The bottom line: don't delay a necessary replacement just to hit a calendar window. The damage from waiting almost always costs more than the savings.

In some cases, yes. This is called a "re-roof" or "overlay", and it's permitted in certain situations where the existing layer is in relatively decent condition. However, most roofing professionals, including the team at LOA, typically recommend a full tear-off for a few reasons:

• A second layer adds significant weight to your structure.
• It traps heat and moisture between layers, shortening the new roof's lifespan.
• You lose the opportunity to inspect and repair the roof deck underneath.
• Many shingle manufacturers void their warranty when products are installed over an existing layer of roofing materials.

Most local building codes also limit roofs to two shingle layers maximum. If your home already has two layers, a full tear-off is required before a new installation.

The cost varies based on the amount of square foot installed, pitch, the shingle grade you choose, and regional labor rates. Generally speaking, homeowners can expect:

• 3-tab asphalt shingles: $4,500 – $8,000 for an average home (1,500–2,000 sq ft of roof area)
• Impact resistant shingles: $4.50-$8.50 per square foot
• Architectural (dimensional) shingles: $7,000 – $14,000 for the most popular mid-range option
• Premium designer shingles: $12,000 – $20,000+ depending on complexity and size

These ranges are strictly estimates that include material and labor. Additional costs may apply for steep roof pitches, extensive decking damage or complex roof lines with many valleys and dormers. The only way to get an accurate number is a proper on-site estimate from a trusted roofing company like LOA.

It depends on what caused the damage. Insurance typically covers sudden, accidental roof damage from hail, wind, falling trees or fire. It generally does not cover damage from age, neglect or normal wear and tear.

Important: Always get your own contractor's inspection before or alongside the insurance adjuster's visit. Having an independent assessment protects you and ensures nothing gets missed. LOA works directly with insurance companies and can help guide you through the claims process.

Several factors can push costs up or down significantly:

• Roof size and complexity — more square footage, steep pitch or many valleys means more labor and material
• Shingle grade — 3-tab vs. architectural vs. impact-resistant premium products
• Tear-off vs. overlay — removing the existing layer adds cost but is usually worth it
• Decking condition — if the plywood sheathing beneath is rotted or damaged, it must be replaced
• Underlayment and ice & water shield — code requirements and quality choices vary
• Ventilation upgrades — improving attic airflow extends shingle life and may be required

A detailed written estimate from a reputable contractor should line-item all of these so there are no surprises.

Yes! LOA Roofing and Construction offers flexible financing options to help make your roof replacement manageable. Beyond our in-house options, homeowners also have access to:

• Home equity loans or HELOCs — low interest rates may be available
• Personal loans — quick approval without tapping into home equity
• Manufacturer financing programs — offered through major shingle brands
• FHA Title I Home Improvement Loans — a government-backed option for qualified homeowners

Ask our team about current financing offers during your free inspection consultation. Delaying a needed roof replacement to save up often results in far greater costs.

These are the three main tiers of asphalt shingles you'll encounter:

• 3-tab shingles — The traditional, flat, single-layer shingle. They're the most affordable option but have a shorter lifespan (15–20 years) and offer less wind resistance. They've become less common for new roof installations.
• Architectural (dimensional) shingles — These are the industry standard today. Made with multiple layers for a textured, dimensional look. They typically last 25–30 years, carry better warranties and hold up well against the wind and inclement weather.
• Premium designer shingles — The top tier option, often replicating the look of slate, wood shake or tile. They offer the longest lifespan (30–50 years), superior impact and wind ratings and the greatest curb appeal at a higher price point.

For most homeowners, architectural shingles represent the best value. LOA can walk you through specific product options based on your home's style and your budget.

A professional roof replacement generally follows these steps:

1. Inspection and estimate — We assess the roof's condition, measure the area and provide a detailed written estimate.

2. Material selection — You choose your shingle style, color and grade.

3. Permits — They are required in most jurisdictions, but LOA handles this on your behalf.

4. Tear-off — Existing shingles and underlayment are removed and disposed of first.

5. Decking inspection and repair — Any damaged plywood is replaced before new materials go down.

6. Underlayment installation — An ice and water shield and synthetic felt are applied.

7. Shingle installation — Starting at the eaves, shingles are installed course by course.

8. Flashing and trim — Metal flashing is installed around chimneys, skylights and valleys.

9. Cleanup and inspection — Magnetic nail sweep, full debris removal and final walkthrough comes last.

For most average-sized homes (1,500–2,500 sq ft of roof area), a full replacement typically takes one to three days. Larger homes, complex roof lines or significant decking repairs can extend this timeline.

Weather is always a factor as well. Work will pause during rain, which can push completion to the following day. The good news: once the crew starts, they're usually done much faster than most homeowners expect.

No, you don't need to be present for the roof removal and installation. As long as our crew has access to the exterior of the home, work can proceed. That said, it's helpful to be available by phone in case the team discovers unexpected decking damage or has questions about material placement.

We recommend being present at the start of the first day for a brief walkthrough and again at the end of the project to inspect the finished work alongside your project manager before final payment.

A little preparation goes a long way toward a smooth roof replacement:

• Clear the driveway and areas around the home for material delivery and debris removal.
• Move vehicles out of the garage (vibration from nailing can occasionally shift items on shelving).
• Take fragile or hanging items off interior walls near the roofline.
• Protect outdoor plants and furniture near the perimeter with tarps (LOA will provide ground tarps as well).
• Arrange childcare or pet care if needed since it will be loud all day.
• Let your immediate neighbors know work is scheduled. They'll appreciate the heads-up.

Lifespan depends heavily on shingle quality, installation workmanship, climate and ventilation:

• 3-tab shingles: 15–20 years
• Architectural shingles: 25–30 years
• Premium designer shingles: 30–50 years

Proper attic and roof ventilation is one of the most underrated factors in shingle longevity. Without adequate airflow, heat and moisture build up and dramatically shorten a roof's life regardless of shingle quality. LOA inspects and addresses ventilation as part of every roof replacement project.

A new asphalt shingle roof comes with two distinct warranty types:

• Manufacturer's material warranty — Covers the shingles themselves against defects. Standard warranties range from 20 to 50 years. Some premium products offer lifetime coverage. Read the fine print because most have prorated coverage after a certain period.
• Contractor's workmanship warranty — Covers installation errors. This varies by contractor. Quality roofers stand behind their work with a minimum 5-year workmanship warranty. LOA offers a comprehensive 10-year workmanship guarantee on every project.

Important: Manufacturer warranties are often voided if the product is installed by an uncertified contractor or over an existing shingle layer. Always verify that your roofer is a certified installer for the shingle brand you're using.

A proper installation is the foundation, but good roof maintenance also extends your roof's life significantly. Invest in:

• Annual inspections — Catch minor issues before they become major ones, especially after severe storms.
• Keep gutters clean — Clogged gutters back up water under shingles and rot the fascia.
• Trim overhanging branches — Branches cause abrasion, retain moisture and can cause impact damage in storms.
• Address moss or algae growth promptly — Algae-resistant shingles help, but treat any growth quickly if it appears.
• Ensure proper attic ventilation — This reduces heat buildup that degrades shingles from the inside out.
• Don't walk on the roof unnecessarily — Foot traffic can crack shingles and loosen granules.

LOA Roofing recommends scheduling a professional inspection every 1–2 years to stay ahead of potential issues.
