CertainTeed Landmark® & NorthGate® Roofing — Installation in Southeast Louisiana
CertainTeed roofing in Southeast Louisiana is a smart choice for homeowners who want lasting curb appeal and reliable storm performance. Our licensed crews install CertainTeed Landmark®, Landmark PRO, and NorthGate® ClimateFlex® architectural shingles across Baton Rouge, Slidell/Northshore, New Orleans/Jefferson, and nearby Mississippi Gulf Coast communities. We pair premium shingles with clean flashing, balanced attic ventilation, and itemized scopes so you know exactly what you’re getting. To see finishes on real homes, browse our project gallery. For ballpark budgets, review our Louisiana roof cost guide.
Why CertainTeed for Gulf Coast roofing
Our climate brings heat, humidity, heavy rain, algae staining, and seasonal winds. CertainTeed roofing systems address each of these with sturdy mat construction, algae-resistant granules, and a full accessory ecosystem (starters, hip & ridge, underlayments). If you’re pursuing storm-hardening, we can also build to the IBHS FORTIFIED™ Roof details — see the grant steps in our Louisiana Fortify Homes Program guide.
Landmark® vs Landmark PRO vs NorthGate® ClimateFlex®
Each line serves a different need while maintaining that dimensional architectural look homeowners love.
- Landmark® — the classic value leader: dimensional appearance, wide color selection, strong warranty foundation, and dependable performance for everyday Louisiana weather.
- Landmark PRO — upgraded visual depth and enhanced long-term algae resistance. If you want a richer color pop and a longer “clean roof” look on the Northshore, this tier is a great fit.
- NorthGate® ClimateFlex® — polymer-modified shingles engineered for tougher weather and flexible handling. A top pick where impact and temperature swings are concerns.

What’s included in a professional CertainTeed installation
A roof is a system, not just shingles. Here’s how we deliver clean looks and long-term performance:
- Assessment & itemized quote. We measure slopes and facets, check deck condition, document current attic ventilation, and inspect wall/chimney flashings. You get a clear, line-by-line proposal with good/better/best options.
- Protection & tear-off. Landscape protection, safe access, full tear-off (layers noted), and deck inspection to catch hidden repairs before shingles go on.
- Underlayments & edges. Synthetic underlayment on the field, valley/wall membranes at critical transitions, and new drip edge for crisp lines and water control.
- Flashing upgrades. Fresh step-flashings at walls and counter-flashing at chimneys — cleanly integrated instead of “gooped” repairs.
- Shingle system. Manufacturer nailing patterns, straight courses, matched hip & ridge components, and ventilation cutouts as specified.
- Balanced ventilation. We size ridge/soffit ventilation to code and climate for cooler attics and longer shingle life — details in our ventilation guide.
- Cleanup & documentation. Magnet sweep, haul-off, and a photo set for your records.
Performance, warranties, and everyday realism (in plain English)
CertainTeed’s warranty platform pairs material coverage with early-life protection periods, wind coverage, and algae resistance (terms vary by line and accessory use). Practically speaking, that means fewer streaks from algae, better hold-up in driving rain, and stronger ridge lines in gusts — when the whole system is installed correctly. We’ll explain the specific warranty terms tied to the product and accessories you choose.
Costs and what drives them
Total price depends on size and geometry (ridges/valleys), layers to remove, decking repairs, flashing complexity, and ventilation components. We never “bundle” unknowns — your quote is itemized so you can see where money goes. For realistic ranges across Louisiana home sizes, visit our roof replacement cost guide. Thinking about gutters while you’re at it? We fabricate on-site for tight, clean lines — see our seamless gutter service.
Color selection and curb appeal
Landmark and Landmark PRO offer broad color palettes from cool grays to warm browns and bold charcoals; NorthGate ClimateFlex follows suit with premium tones that pair well with brick and stucco. We’ll suggest colors that complement your siding, trim, and brickwork, then show you the look in our local gallery so you can choose with confidence.
FORTIFIED™ path & Louisiana Fortify Homes ($10,000 grant)
If you want storm-smart details — stronger edges, sealed deck, enhanced underlayment — we can align your roof to the IBHS FORTIFIED™ checklist. Homeowners may also be eligible for $10,000 toward upgrades under the state program. Learn how to prep documents, timing, and evaluator coordination in our LFHP grant guide.
Real-world results we target on every install
- Cleaner rooflines with crisp hips/ridges and even courses.
- Dry valleys & walls thanks to proper membranes and flashing upgrades.
- Cooler attics from balanced ridge/soffit ventilation sized to your roof area.
- Less staining from algae-resistant shingles, especially on north-facing slopes.
You can see these details in finished projects throughout our photo gallery.

We serve Baton Rouge, Prairieville, Denham Springs, Gonzales, Zachary, Slidell, Mandeville, Covington, New Orleans/Jefferson, and nearby Mississippi Gulf Coast cities. Unsure if you’re in range? Send a quick note with your address and a couple of photos — we’ll confirm coverage and propose times.
Homeowner checklist: how to compare roofing quotes fairly
- Scope apples-to-apples. Make sure each bid states tear-off layers, underlayments, drip edge, valley/wall membranes, and ventilation.
- Flashing plan. Step-flashing at walls and counter-flashing at chimneys should be replaced — not “sealed over.”
- Accessories match. Confirm manufacturer-matched starter and hip/ridge to support wind and algae warranties.
- Decking policy. Ask how damaged sheathing is handled and priced.
- Cleanup guarantees. Look for daily magnet sweeps and haul-off in writing.
FAQ — CertainTeed Landmark®, Landmark PRO & NorthGate® ClimateFlex®
Which line is the best value for most Louisiana homes?
Landmark® is a great value with strong aesthetics and warranty coverage. If you want a richer look and enhanced long-term algae resistance, Landmark PRO is the next step up.
When should I consider NorthGate® ClimateFlex®?
Choose NorthGate® ClimateFlex® when you want a polymer-modified, impact-resistant option and smooth handling during cooler-weather installs — popular on the Northshore and open exposures.
Can these shingles be used in a FORTIFIED™ roof?
Yes — when the entire roof is installed to the IBHS FORTIFIED™ details (edge metal, sealed deck, underlayment, fasteners, and documentation). See the process and timing in our LFHP guide.
Will better ventilation really matter?
Balanced ridge/soffit ventilation helps lower attic heat and moisture swings, which supports shingle life, improves comfort, and reduces the chance of mildew in the attic.
How do I keep the roof looking clean?
Choose algae-resistant lines and keep gutters and valleys clear. Trim overhanging branches to reduce debris and abrasion.
What does a typical timeline look like?
After your estimate is approved, most single-family homes take 1–3 days on site (weather-permitting). Complex flashing or decking repairs can add time; we’ll note that in your proposal.
