No Guesswork. No Pressure. Just an Honest Number.
Most Roofers Quote Fast. We Quote Right.
Most homeowners replace their roof once, maybe twice in a lifetime. That’s exactly why so many contractors treat the quote like a formality — get in, throw out a number, close the deal.
That’s not how we operate. Bergens Roofing was built on repeat business and referrals across St. Tammany. Our reputation depends on giving you a quote that actually reflects what your roof needs — not what’s easiest to sell.
- No high-pressure tactics or artificial urgency
- No vague estimates without documentation
- No upselling work you don’t need
- No disappearing after the check clears
Just honest roofing from a team that’s been showing up in this community since 1989.
What Every Bergens Quote Covers
A real proposal isn’t just a price — it’s a roadmap. When we hand you a quote, it includes:
- Roof dimensions, slope, and total square footage
- Underlayment specifications and ice and water shield details
- Ventilation assessment — critical in Louisiana’s humidity
- Decking condition report with photos
- Material options by tier with brand and warranty details
- Full tear-off, haul-away, and cleanup scope
- Labor timeline and crew details
- FORTIFIED Roof eligibility check and grant potential
If another contractor’s quote doesn’t cover these, it’s not a complete quote.
Questions Worth Asking Any Roofer
- Do you show photos of every problem area — not just describe them?
- Do you address attic ventilation or only the shingles?
- Do you offer material options at different price points?
- Is your workmanship warranty in writing?
- Are you a licensed Louisiana contractor with verifiable references?
Why Roof Costs Vary in South Louisiana
St. Tammany roofs deal with things most of the country doesn’t — sustained humidity, brutal UV exposure, and a very real hurricane season. These factors shape every quote we write.
Roof Size and Layout
Square footage is just the start. Hip roofs, multiple valleys, and penetrations all affect labor hours and material waste.
Tear-Off Requirements
Louisiana building code and FORTIFIED certification both require full tear-off. Overlays save money short-term and cost more long-term.
Ventilation Conditions
An under-ventilated attic in Slidell will destroy a new roof in 8-10 years. We always assess this before pricing.
Material Tier
We offer standard architectural, GAF Timberline HDZ, and impact-resistant options — each with different storm performance profiles.
FORTIFIED Certification
Qualifying St. Tammany homeowners may access Louisiana grants up to $10,000 and meaningful insurance premium reductions.
Decking and Flashing Condition
We document what’s under the shingles before we price it — not after we’ve already started tearing off.
What an Asphalt Shingle Roof Costs in South Louisiana
Most roofers won’t put a number on their site. We will. A new asphalt shingle roof from Bergen’s runs $4–$5 per square foot of roof surface, before the waste factor is applied. Where you land in that range depends on the same handful of factors every time:
- Roof pitch — steeper roofs take longer and require more safety staging.
- Roof height — multi-story homes add staging and labor.
- Flashings — chimneys, skylights, walls, and pipe penetrations all need new flashing.
- Ventilation — bringing the attic up to proper intake/exhaust often means new ridge vent and soffit work.
The Waste Factor (7–18%)
Every roof has a waste factor — the extra material we order to cover cuts, valleys, hips, and starter rows. The more complex the roof, the higher the waste.
- 7–10% — simple gable roof, few penetrations, low pitch
- 10–14% — moderate complexity: a couple of valleys, a dormer, standard pitch
- 14–18% — complex roof: multiple facets, valleys, hips, dormers, steep pitch
A 2,800 sq ft roof with a 12% waste factor is priced like ~3,136 sq ft of material.
Price Ranges by Home Size
Small home — ~1,800 sq ft of roof
Simple gable roof, low pitch, minimal penetrations. Waste factor: 7–10%.
Estimated price: $7,700 – $9,900
Medium home — ~2,800 sq ft of roof
Moderate complexity, a couple of valleys, a dormer, standard pitch. Waste factor: 10–14%.
Estimated price: $12,300 – $16,000
Large home — ~4,000 sq ft of roof
Complex roof with multiple facets, valleys, hips, dormers, steep pitch. Waste factor: 14–18%.
Estimated price: $18,200 – $23,600
Pricing above is for asphalt shingle roofs only. Metal, tile, and specialty roofing systems are priced separately. FORTIFIED roof systems, premium GAF designer shingles, and significant decking or rotten-wood repairs may carry additional cost. An on-site inspection is the only way to give you a firm number — every roof is different.

Pricing FAQs
How much does a new asphalt shingle roof cost?
A new asphalt shingle roof from Bergen’s Roofing runs $4–$5 per square foot of roof surface, plus a 7–18% waste factor depending on roof complexity. For a typical Louisiana home, that works out to roughly $7,700–$23,600 depending on roof size, pitch, and how cut-up the roof design is.
What is a waste factor in roofing?
The waste factor is the extra roofing material we order to cover cuts, valleys, hips, and starter rows. A simple gable roof might only require 7–10% extra material. A complex roof with multiple facets, valleys, hips, and dormers can require 14–18%. The waste factor is applied to the measured square footage of the roof to determine how much material is actually ordered and priced.
What affects the final price of my new roof?
Four factors move your price within the $4–$5 per square foot range: roof pitch (steeper roofs cost more to install safely), roof height (multi-story homes need more staging), flashings (chimneys, skylights, walls, and pipe penetrations all need new flashing), and ventilation (bringing the attic up to proper intake/exhaust often involves new ridge vent and soffit work). More complex roof designs — more facets, valleys, hips, and dormers — push the waste factor higher.
Why don't you just give me one flat price per square foot?
Because two roofs of the same square footage can require very different amounts of labor and material. A 2,800 sq ft roof on a single-story ranch with a simple gable is genuinely cheaper to install than a 2,800 sq ft roof on a two-story home with three valleys, two dormers, and a 12/12 pitch. A range plus a free inspection is the honest way to price it.
Will the price change after I sign the contract?
No. Once we inspect the roof and give you a quote, that’s the price — we don’t quote low and then come back asking for more. The only exception is if we open the roof during tear-off and find significant decking damage or rotten wood that wasn’t visible from above. In that case, we stop, show you the damage, and price the repair before continuing. No surprises.
Do these prices cover FORTIFIED roofs?
No. The pricing on this page is for standard asphalt shingle roof replacements. FORTIFIED roof systems — installed to the IBHS FORTIFIED standard for hurricane resilience — require additional materials (enhanced underlayment, sealed deck, ring-shank nails) and inspection certifications. Louisiana homeowners may qualify for the Louisiana Fortify Homes Program grant to offset that cost. Ask us during your free inspection.

Warning Signs in a Low-Ball Quote
They skip ventilation entirely
In Louisiana’s climate, ventilation isn’t optional. A roofer who ignores it is either inexperienced or cutting corners.
No photos from the inspection
If they can’t show you what they found, you have no basis for trusting what they’re proposing to fix.
Handshake deals only
Every scope of work, warranty, and material specification should be documented before any money changes hands.
The price drops the moment you hesitate
That’s not a discount — that’s a signal the first number wasn’t honest.
Storm chasers and out-of-state crews
After a major weather event, contractors flood in from other states. Bergens has been here since 1989 and will be here when you need warranty work done.
No workmanship warranty
We back our work with a 15-year workmanship warranty and GAF material coverage up to 50 years non-prorated.
Repair or Full Replacement? Here’s How We Think About It.
We don’t default to the most expensive option. We look at the evidence and tell you what the roof actually needs.
A targeted repair usually makes sense when:
- Damage is limited to one area and shingles are still performing elsewhere
- The roof is under 10 years old with no prior repairs
- Wind or storm damage is isolated and well-documented for insurance
A full replacement is typically the right call when:
- Shingles are granule-depleted, brittle, or lifting at multiple points
- You’re seeing leaks in more than one location
- The roof is 15+ years old in our climate
- You want to qualify for FORTIFIED certification and Louisiana grant funds
- Your insurer is flagging the roof or denying continued coverage
We lay out the options clearly. The decision is always yours.
Financing That Actually Works
