Whether you’re buying an existing home or building from scratch, the roof is one of the few systems that can blindside you with five-figure costs years after you move in. Here’s what to ask, what to look for, and how to plan for the roof you’re about to inherit or build.
If You’re Buying an Existing Home
Before closing, find out three things about the roof:
- Age. Most asphalt shingle roofs in Louisiana last 20–25 years. If the roof is older than 15, you’re within 5–10 years of replacement and need to budget for it.
- Maintenance history. Ask the seller for documentation of inspections, repairs, or maintenance. If they can’t provide any, assume the roof hasn’t been actively maintained.
- The original installer. If the roof was recently replaced, the contractor’s name matters, it tells you whether the workmanship warranty is still valid and who to call if issues come up.
A standard home inspection includes the roof, but the inspector typically isn’t a roofer. For older homes, or if the home inspector flags anything, get a separate professional roof inspection before closing. The cost is modest, and it gives you real negotiating leverage if there are issues. You can ask the seller to credit the price, replace the roof, or split the cost.
If You’re Building New
For new construction, the decisions you make at the roof stage will shape your home’s energy bills, maintenance load, and storm resilience for the next 20+ years. Three things to think through:
Material selection. Asphalt shingles are the default for most Louisiana homes, but metal, tile, and fortified options each offer tradeoffs in cost, lifespan, and storm performance. Choose to fit your long-term plans for the home, not just the builder’s standard package.
Ventilation design. Proper soffit-to-ridge ventilation isn’t optional in our climate, it directly affects attic temperatures, energy bills, and how long the roof will last. Make sure the roofing subcontractor designs ventilation as a system, not an afterthought.
Contractor selection. Your builder typically subcontracts the roof. Ask which company is doing yours, and verify their license, insurance, and manufacturer certifications. Most roof issues that appear in years 3–7 of a new home are installation problems, not material problems.
First-Year Maintenance Basics
Whether the roof is new or just new to you, set up these habits in the first year:
- Schedule an annual professional inspection. Small issues caught early cost a fraction of what they cost after a leak appears.
- Clean your gutters at least twice yearly plus after major storms. Blocked gutters back water up under the roof edge and rot the soffit and fascia.
- Trim back overhanging branches. Branches that touch or rub the roof damage shingles and create entry points for water and pests.
- Keep the roof surface clear. Debris and moss hold moisture against the shingles and accelerate aging.
A consistent roof maintenance routine typically pays for itself many times over through avoided emergency repairs and a longer overall roof life.
What to Do Next
If you’re buying, get a professional roof inspection before you close. If you’re building, ask your builder who’s installing the roof and verify their credentials. Either way, knowing what you’re dealing with up front is far cheaper than finding out later.

Frequently Asked Questions
Should I get a separate roof inspection when buying a home?
A standard home inspection covers the roof briefly, but the inspector typically isn’t a roofer. For homes more than 10 years old, or if the home inspector flags any concerns, a dedicated roof inspection by a roofing professional gives a far more accurate picture of remaining life and current issues. Most reputable roofing companies offer these inspections free or at low cost.
How can I tell how old a roof is?
Ask the seller directly, they should know or have documentation. Property records sometimes show roof permits, which include install dates. A roofing professional can also estimate age within a few years by examining the materials, granule loss, and overall condition. The roof’s age relative to its rated lifespan is one of the most important factors in deciding whether to negotiate replacement into the sale.
Should the seller pay to replace a failing roof?
A failing roof is one of the most common items buyers negotiate over. Options include the seller crediting you cash at closing, reducing the sale price by the replacement cost, or replacing the roof themselves before closing. A professional roof inspection report gives you the documentation to make a credible negotiating ask.
