New Roof Installation — New Construction & Additions in Southeast Louisiana
Building a new home or planning an addition in Southeast Louisiana deserves a roof that’s designed — not just installed. Our roofing contractor team engineers a code-compliant new roof installation for Gulf Coast wind, rain, and humidity, coordinates cleanly with your GC and permits, and documents every step with photos.

This page focuses on new construction roof installation and roof installation for additions — not replacements on aging roofs. If your existing system is worn or storm-damaged, use our Roof Replacement hub and compare budgets in the Cost of a New Roof in Louisiana guide.
Our Build-First Process
Long-term performance is won at the edges, penetrations, and vents. Before the first shingle goes on, we plan the roof system for water control, ventilation, and clean tie-ins to the new structure.
- Preconstruction review — plans, slopes, drainage, and tie-ins to existing rooflines
- Material submittals — underlayment, shingles, flashings, intake and exhaust components
- Dry-in — synthetic underlayment, membrane at eaves/valleys, and critical flashing prep
- Final installation — correct nailing patterns, ridge/hip finishing, balanced ventilation
- Close-out — photo log, care tips, and simple maintenance schedule
The result is a quiet, durable new roof that sheds heavy rain and resists coastal winds — backed by clear documentation for your records.

Design & Building Science for the Gulf Climate
Southeast Louisiana combines high humidity, wind-driven rain, and heat. We size and place components so the roof system manages moisture and pressure changes — not just “meets code on paper”.
Balanced Intake and Exhaust
We calculate net free area for soffit intake and ridge or roof exhaust, confirm baffle paths over insulation, and keep airflow continuous through hips, dormers, and step-downs. Proper ventilation reduces heat load, protects shingle seal strips, and supports manufacturer wind ratings.
Smart Layout for Additions
Additions change airflow and water paths. We prevent dead zones by aligning new soffit intake with existing eaves, isolating vaulted bays, and avoiding shortcuts like venting into the attic. Clean transitions keep both the new roof and the original roof performing as one system.
Moisture Control & Vented Devices
Bath and kitchen exhausts must terminate outdoors — never into attic spaces. We specify proper hoods, sealed penetrations, and back-draft control so humidity exits the building envelope instead of condensing on decking.
Wind Uplift & Fastener Strategy
We match shingle systems and fasteners to exposure and architecture — six-nail patterns where required, starter alignment at eaves and rakes, and reinforced hip/ridge details for coastal gusts. Details like these are small on paper — and huge during storm season.
Flashings & Penetrations — Where Roofs Win or Fail
Flashing geometry matters more than any brand name. We follow manufacturer specs and local best practices so water always has a clean exit path away from the structure.
- Wall step flashing with counter-flashing and kick-outs at cladding transitions
- Chimney systems with crickets where needed and replaceable counter-flashing
- Pipe boots with protected fasteners and correct shingle integration
- Skylight preparation with approved flashing kits and curb blocking
- Valley metal or woven layouts based on slope, exposure, and aesthetic
Every penetration is photographed during install — a permanent record that simplifies future maintenance and resale disclosures.
Materials & System Options
Every project is different, but our goal is consistent — a durable new roof installation that handles wind-driven rain and looks right on your home.
Underlayments & Seal Zones
We use high-grade synthetic underlayment for the field and apply self-adhered membrane at eaves, valleys, and other risk areas. For added resilience, consider a sealed-deck pathway through our Certified FORTIFIED™ Roof Installation options.
Architectural Shingle Systems & Wind Ratings
Architectural shingles are chosen for color, profile, and wind rating appropriate to the site. We pair them with compatible starters, caps, and approved fasteners — a complete system, not a mix-and-match bundle.
Ventilation & Roof Accessories
Ridge vents, intake solutions, and accessory flashings are selected as a set so airflow, fastening, and warranties align. Where aesthetics matter, we balance low-profile hardware with performance targets.
Skylights, Solar & Future-Proofing
If you’re planning skylights or future solar, we frame and flash with that in mind — proper curb heights, pathways for conductors, and clearances that preserve drainage and ventilation.
Additions & Tie-Ins — Clean Transitions to the Existing Home
Additions create complexity at valleys and walls. We design step-downs, saddles, and shared valleys so water flows away from siding and trim — not into them.
- Tie-ins that preserve valley flow and avoid reverse laps
- Sequencing with siding and WRB so flashing sits in the right layer
- Fast, watertight dry-in that protects interiors while other trades finish
After tie-ins, we re-check ventilation math to keep the combined roof system balanced across old and new spaces.
Scheduling, Permits & Site Cleanliness
We coordinate with your GC and inspectors so the project stays on track — and your property stays tidy from start to finish.
- Confirmed dates tied to framing milestones and fair-weather windows
- Protected landscaping, daily debris removal, and magnet sweeps
- Walkthrough at dry-in and final completion with sign-off photos
You get a clear contact, a predictable schedule, and a site that looks as good as the roof.
Pricing, Proposals & Resilience Upgrades
New-construction pricing depends on roof area, geometry, materials, and the number of penetrations. We provide transparent, line-item proposals with alternates for resilience and ventilation upgrades. If you’re comparing replacement vs. new build on the same property, review our Roof Replacement hub and the Cost of a New Roof in Louisiana guide for apples-to-apples context.

FAQs — New Roof Installation
Below are quick answers about planning and executing a code-compliant roof installation for new construction and additions in Southeast Louisiana.
Do you coordinate with my general contractor?
Yes — we align schedules, submittals, and inspections with your builder so the roof system is ready when framing and mechanicals are ready. Clear coordination reduces delays and protects finished interiors.
Can you design the ventilation for my addition?
Absolutely. We calculate intake and exhaust for the combined attic volume, adjust for vaulted spaces, and verify that baffles keep air moving over insulation — a key to roof longevity in our climate.
What if I want extra storm resilience without changing the design?
Consider sealed-deck pathways, reinforced edges, and upgraded fasteners via our Certified FORTIFIED™ Roof Installation options — low-visibility upgrades that pay off in wind-driven rain.
How do you handle skylights, chimneys, and complex valleys?
We use manufacturer-approved flashing kits, cricket design where needed, and step/counter-flashing sequences that prioritize drainage. Complex geometry is documented with photos so future maintenance stays simple.
