Mississippi Windpool to Raise Rates by 16% on January 1, 2026 — What Gulf Coast Homeowners Can Do Right Now

Coastal Mississippi homeowners are facing a confirmed increase in wind and hail premiums: the Mississippi Windstorm Underwriting Association (MWUA, the “windpool”) is set to raise rates by 16% on January 1, 2026. For property owners in Hancock, Harrison, Jackson, Pearl River, Stone, and George counties, this is more than a budget headline — it is a prompt to tighten the building envelope, document resilience upgrades, and clean up insurance paperwork before renewal season; the best starting points are a proactive free roof inspection and a code-aware roof replacement plan aligned to coastal conditions.

What Changed — 16% Windpool Increase Effective January 1, 2026

The windpool is a state-created backstop that offers wind and hail coverage where the private market is thin or unavailable, and beginning on January 1, 2026, MWUA will implement a 16% rate increase for policies in its service area; while individual renewals vary by coverage and deductibles, the headline number is clear enough to warrant planning, including scoped maintenance and, where needed, documented storm damage roof restoration to stabilize known leak paths before renewal.

Who Is Affected — The Six Coastal Counties and Nearby Communities

MWUA specifically serves Mississippi’s six southernmost counties commonly referred to as the Coastal Counties, and if you live in or near Biloxi and have been weighing a replacement, it is worth reviewing assemblies and timelines on our regional page for roof replacement in Biloxi, MS to understand scope planning under coastal exposures.

• Hancock County — from Bay St. Louis to Waveland, homes face surge, wind, and salt; baseline the roof with a photo-rich inspection before renewal.
• Harrison County — including Gulfport and Biloxi where hurricane bands bring long-duration wind and rain; a code-aware roof replacement with correct edge metals pays off here.
• Jackson County — Pascagoula and Ocean Springs see lateral wind loads and wind-driven rain; align repairs to the storm restoration best-practice flow.
• Pearl River County — inland but hit by severe rain bands; right-size drainage with 6″ seamless gutters and 3×4″ downspouts.
• Stone County — feeder bands dump heavy rain on older roofs; verify underlayment laps during any replacement or repair scope.
• George County — inland drainage and wind events still matter; start with a quick 15-minute exterior checkup to flag weak points.

Risk varies inside a single county based on elevation, setbacks, and roof history, and two similar houses can perform very differently in a storm if one has a sealed deck and locked-down edges while the other has gaps at decking joints; if unknown, schedule a no-cost inspection and get a written baseline with photos.

Why Rates Are Rising — Reinsurance, Weather Volatility, and Policy Choices

Coastal insurance is governed by reinsurance pricing and catastrophe models, and when reinsurance is expensive or models point to higher expected losses, state backstops adjust rates to stay solvent; homeowners cannot influence global reinsurance, but they can control how roofs and exteriors manage wind-driven rain and uplift by adopting FORTIFIED™ Roof principles and documenting assemblies for the insurance file.

First Steps This Month — A Quick Risk Triage for Your Home

Before jumping to big-ticket replacements, start with a structured triage so you can isolate repeat failure modes that turn minor issues into claims; use the checkpoints below and then hand off to a pro for confirmation and a written scope that fits renewal timing.

• Self-check in 15 minutes: use the 15-minute roof & exterior checkup to spot lifted shingles at rakes/eaves, brittle edge metal, missing flashing sealant, clogged gutters, and downspouts discharging at the slab.
• Book a documented inspection: if anything looks marginal or you want ventilation math and photos, schedule a free roof inspection and keep the report as your first renewal document.
• Stabilize drainage: heavy bands overwhelm small outlets, so step up to 6″ gutters with 3×4″ downspouts to cut fascia rot and siding streaks.
• Fix known water paths: if you have recurring stains or wind-driven rain history, follow the storm restoration flow for dry-ins, flashing, and scoped repairs.

If your triage suggests larger work, align timing and cash flow using the roof replacement financing options so necessary scope does not stall during renewal season.

Roof & Exterior Upgrades That Actually Reduce Losses on the Coast

Insurers care about what fails first, not brand names, and on the Gulf Coast the biggest drivers of loss are water entry and edge failures; the upgrades below directly target those modes and map to common insurer questions, with links to deeper guides covering assemblies and field examples.

• FORTIFIED™ Roof details for water control: a sealed deck and locked-down edges keep rain out even if shingles are compromised during a storm, and you can see a field example in our recent install.
• Code-aware roof replacement: correct nailing patterns, sealed underlayment laps, kick-out flashing at wall transitions, and properly sized drip edge matter more than brand; start with a documented inspection to prioritize.
• Storm repair done cleanly: if the last season left lifted tabs or chimney/vent leaks, use the restoration process for fast dry-ins and scoped repairs that prevent secondary damage.
• Right-sized drainage: reduce valley overflows and keep cladding clean with seamless gutters and correctly placed outlets and extensions.
• Energy-smart windows: stabilize indoor temps and reduce glare with replacement windows specified for Gulf weather and paired with tuned attic ventilation during roof work.

Not every home needs every upgrade, but if you want a single high-leverage move, prioritize sealing the roof deck and securing edges first because a small share of roof area represents a large share of storm losses; when you are ready to sequence scope sensibly, request a free estimate and we will align components to your budget and timeline.

Paperwork & Credits — Organize Files to Speed Claims and Capture Incentives

Program credits vary by carrier and year, but one constant remains: clear documentation; homeowners who keep simple, verifiable files tend to have faster agent conversations and better chances of capturing available credits, so use the framework below before renewal notices arrive.

• Photo audit: create a dated album of roof edges, penetrations, valleys, and attic transitions, and after a pro visit add the inspection photos and mark areas that were repaired.
• Materials & methods: save scopes, invoices, and manufacturer cut sheets for underlayments, edge metals, fasteners, and vents to tie directly to roof replacement specifications.
• Resilience proofs: if you pursue a FORTIFIED™ Roof, keep evaluator paperwork, deck-seal photos, and final certificates together and ask your agent which forms trigger credits.
• Drainage & moisture control: add a gutter layout showing 6″ runs and 3×4″ downspouts; see our comparison of 6″ vs 5″ gutters for Gulf Coast volumes.
• Budget smoothing: if timing is tight, use financing & payment options so you do not defer critical scope into peak storm months.

These are practical ways to show your home is getting less risky rather than legal or tax advice, and the more obvious that story is to an insurer the better your position when rates are trending up across the pool; when you are ready, lock a time for a free estimate and we will package photos and scope for your records.

FAQ — Mississippi Windpool Increase and Coastal Home Upgrades

Is the 16% rate increase final? Public statements indicate that MWUA rates will increase by 16% effective January 1, 2026, and your actual premium will reflect dwelling characteristics, deductibles, and endorsements, so confirm specifics with your agent while you take advantage of a no-cost inspection to get ahead of issues.

Will a FORTIFIED™ Roof lower my premium? Credits and documentation vary by carrier and program year, and since FORTIFIED™ focuses on water entry and structural failures at the roof deck and edges you should review the homeowner explainer for FORTIFIED™ Roof basics and ask your agent about current credits and required forms.

Which counties are in the windpool? Hancock, Harrison, Jackson, Pearl River, Stone, and George counties are the core service area, and if you are on the Coast near Biloxi and need scope guidance see roof replacement in Biloxi for typical assemblies.

Do replacement windows matter for insurance? Energy-efficient Low-E/argon windows primarily affect comfort and utility bills, but impact-rated packages can reduce risk from windborne debris, so compare options in our replacement windows guide and pair them with edge-focused roof work.

What if I cannot do everything at once? Prioritize high-leverage items that reduce water entry during storms such as deck sealing, edge metals, and underlayment laps, then add gutters and downspouts to control sheet flow using the seamless gutters playbook, and if needed smooth costs with financing.
