Hurricane Prep for Maryland Homeowners (2026 Roof-First Guide)
Maryland's hurricane reality is wind plus rain damage, not Florida-style Cat 5 prep. Only 3 hurricanes have directly hit Maryland since 1851 (per the MD State Climatologist), and never a major (Cat 3+). What MD does get: tropical storms, nor'easters, hurricane remnants. Prepare the roof for that pattern. Highest-value pre-season actions: HAAG-certified inspection, gutter clear, trim branches within 10 feet, verify ASTM D7158 wind class compliance.
Maryland hurricane prep gets miscalibrated when homeowners borrow the Florida playbook. The historical record says something different: per the Maryland State Climatologist Office, only three hurricanes have directly hit Maryland since recording began in 1851, all Category 1 or 2, never a major hurricane. What Maryland actually gets is wind plus rain damage from tropical storms and hurricane remnants (Isabel 2003, Sandy 2012, Isaias 2020). The roof-first preparation that matters: a pre-season HAAG-certified inspection (free for homeowners in the JDH service area), gutter clearance, branch trimming within 10 feet, ASTM D7158 wind class compliance (Class H for coastal counties per FEMA P-804), and a forensic post-storm response protocol that protects insurance claim approval.
The Maryland-specific hurricane prep timeline, from pre-season inspection to post-storm response
Read these in order. They are the same seven conversations a HAAG-certified inspector has with a homeowner at the kitchen table before any contract gets signed or any shingle gets ordered.
Maryland's hurricane reality: what actually happens here
Maryland's documented hurricane history is short. Per the Maryland State Climatologist Office, only three hurricanes have directly hit the state since recording began in 1851: an unnamed Category 2 in October 1878, an unnamed Category 1 in 1893, and an unnamed Category 1 in 1933. Never a major hurricane (Category 3 or higher). The Florida-style prep playbook is calibrated wrong for the actual MD threat.
What MD does get every season
Tropical storms (Isabel 2003, Sandy 2012, Isaias 2020 all weakened from hurricane to tropical or extratropical before reaching MD), nor'easters that produce hurricane-force wind without the official designation, hurricane remnants pulled inland by coastal lows, and the offshore-passing systems that throw wind and rain at the coast for 36 to 72 hours. The NWS Storm Events Database indexes named MD storm events by county.
The damage pattern that actually hits MD roofs
Wind-driven rain (not impact damage from missiles, like Florida). Tree branch impact during sustained 50-70 mph winds. Gutter overflow into eaves causing soffit and fascia rot. Granule loss accelerated by horizontal rain stripping aging shingles. Flashing fatigue exposed by 36-hour rain events. Decking moisture from inadequate ventilation under prolonged high humidity.
The prep that matches the threat
Roof-first preparation. Gutter clearance. Tree branch trimming. ASTM D7158 wind class verification on existing shingles (Class H for coastal counties per FEMA P-804 wind retrofit guidance). Documented pre-storm condition for any future insurance claim. Save the boarding-windows budget for a Florida vacation.
The pre-season inspection: what JDH documents 30-60 days before June 1
The single highest-value pre-season action for a Maryland roof is a HAAG-certified inspection that documents current condition and identifies failure patterns. JDH inspections are free for homeowners in our Calvert, St. Mary's, Charles, Anne Arundel, and Prince George's service areas; about 1 in 4 result in zero recommended work, which is itself a useful confirmation.
The seven things HAAG inspectors check on every pre-season roof
- Granule loss + sealant strip integrity - hand-lifted shingle test at multiple locations
- Flashing condition at every penetration - pipe boots, chimney, valley, wall transitions
- Decking moisture + deflection - underfoot survey + moisture meter readings through attic
- Attic ventilation calculation - matched against manufacturer spec per IRC R806
- Ice-and-water shield coverage - eaves, valleys, penetrations
- Fastener back-out + nail-line gaps - hand-lift sample inspection
- Wind-rating verification - confirm installed shingles meet ASTM D7158 class appropriate for the county
What goes in the report
PCC Method (Problem, Cause, Consequence) on every finding. Photo and video documentation. Remaining useful life estimate. Cost-to-cure for any defects. Pre-storm baseline that becomes critical if a claim is filed later. Delivered before the inspector leaves the property.
HAAG Education: same credential the insurance adjuster carriesThe 72-hours-before checklist: when a named storm is tracking toward MD
National Hurricane Center cone projections become reliable for Maryland approximately 72 hours before potential impact. That window is when the final controllable prep happens. The work assumes pre-season inspection is already complete - this is the storm-specific layer on top.
Final gutter clear (if needed)
If leaves or debris have accumulated since pre-season clear, do it now. Blocked gutters during a 36-hour rain event cause more soffit and fascia damage than any other single factor in MD. Use a leaf-blower from a stable ladder; do not climb onto the roof.
Tree assessment - cut what you should have cut
Any branch within 10 feet of the roof that you have been meaning to cut: cut it now. Dead branches, leaning trees, mature oaks weakened by lightning. Tree damage is the single biggest controllable hurricane-season risk in MD. An arborist who can do same-day or 48-hour work is more valuable than a contractor at this stage.
Outdoor item triage
Three categories: secured (anchor to ground, like grills with proper anchor kits), stored (move to garage or basement - patio furniture, planters, umbrellas, propane tanks not in use), or removed (trampolines, anything that becomes airborne over 50 mph). Practice the sweep before you need it.
Document pre-storm condition
Take photos of each roof slope from the ground. Phone metadata timestamps are sufficient for insurance documentation. Take photos of the gutter clear, the secured outdoor items, the trimmed branches. These become the pre-storm baseline if any claim is filed.
Verify insurance + claim contact info
Pull your policy declarations page. Confirm wind coverage. Confirm whether your hurricane deductible is separate (common in MD). Confirm whether your roof is on ACV (depreciated) or RCV (replacement cost). Save your carrier claim hotline + JDH emergency tarp number ((443) 241-7356) in your phone.
The 24-hours-before final pass and shelter-in-place prep
When NHC forecasts narrow inside 24 hours of impact, outdoor prep windows close. Focus shifts to shelter-in-place readiness and the final 30-minute outdoor sweep.
Final outdoor sweep (30 minutes)
Walk the perimeter. Anything still outside that can lift in 60+ mph wind goes inside or gets secured. Trash and recycling bins. Garden tools. Hose reels. Bird feeders. Wreaths. Dish satellites already-loose or weather-fatigued mounts should be addressed before any home improvement post-storm crew arrives.
Vehicle staging
Move vehicles to the garage if possible. Otherwise park away from mature trees, branches that overhang, and dish satellite mounts. Avoid parking under any tree that has shown weakness (leaning, dead limbs, prior storm damage).
Shelter-in-place supplies
Per the National Weather Service hurricane plan: 1 gallon of water per person per day for 3 days, non-perishable food for 3 days, flashlights + extra batteries, battery-powered radio (NOAA weather radio if possible), first-aid kit, medications for 7+ days, phone chargers (battery banks fully charged), cash in small bills (ATMs and credit card systems often fail).
Safest location inside the home
Per NWS guidance: a small interior room, closet, or hallway on the lowest level. Away from windows. Away from exterior doors. Away from large interior spans (open kitchens, great rooms) where roof failure would be most dangerous if it happened. Walk through with all family members so the plan is shared.
Pre-storm photo refresh
Take final timestamped photos of every roof slope and the perimeter. These are the strongest pre-storm evidence baseline for any later claim. Phone-stored, cloud-backed up if possible.
Post-storm response: the order that protects insurance claim approval
The single most common reason a Maryland hurricane claim gets denied is filing-before-documenting. The adjuster's inspection becomes the record, and aging-roof findings get classified as wear-and-tear instead of storm damage. The correct order matters.
Step 1 - Safe ground-level + interior assessment
Do NOT climb onto a wet or wind-active roof. NWS data consistently lists fall injuries as a top post-storm cause of injury. From the ground: photograph any visible roof damage. From inside: check ceilings for active leaks, check the attic for any new water staining. Document what you find with timestamped photos.
Step 2 - Emergency tarp if active leaking
If water is actively entering the home, call for emergency tarp service. JDH offers same-day emergency tarp placement in our Maryland service area during named storm events. A safely-placed temporary tarp by a certified inspector prevents the secondary damage that compounds repair costs.
Step 3 - HAAG-certified independent inspection BEFORE calling the carrier
Schedule the inspection before filing the claim. The inspection report with PCC Method (Problem, Cause, Consequence) findings becomes the documentation that establishes storm correlation. Without it, the adjuster's inspection becomes the only record, and storm damage on an aging roof often gets reclassified as wear-and-tear.
Step 4 - Decide whether to file
Compare documented damage cost against deductible. If damage is below or near deductible, the claim usually creates more risk (carrier records, potential non-renewal) than it provides benefit. JDH never recommends filing a claim; we document what is on the roof and let the homeowner decide. See the storm damage insurance claims walkthrough for the full decision framework.
Step 5 - If filing, the adjuster meeting
JDH walks the roof with the adjuster on every covered claim. Same HAAG credential. Same vocabulary. The PCC Method documentation is already in hand. The meeting becomes a technicality, not a negotiation.

Annual Hurricane Prep Checklist for Maryland Homeowners
A six-step seasonal hurricane prep timeline. Start by June 1 each year; reconfirm in late August before peak season. The whole annual cycle takes about 14 days of elapsed time with most of the work front-loaded into May.
April-May: Schedule the pre-season inspection
Book a HAAG-certified inspection 30-60 days before June 1 so any recommended work completes before peak season. JDH inspections are free for Maryland homeowners in our service area.
May-June: Complete pre-season maintenance
Clear gutters, trim branches, inspect/replace flashing, verify ventilation, confirm wind-rating compliance. Document current condition with photos.
August 1: Mid-season recheck
Mid-summer gutter check (catches leaf accumulation), photo baseline refresh, confirm insurance policy is current. Most active hurricane risk runs August through October.
72 hours before a named storm
Final gutter clear, secure or store outdoor items, review evacuation plan, charge phones and battery backups, prepare emergency supplies (water, food, flashlights, batteries, first aid).
24 hours before landfall or projected impact
Final outdoor sweep (anything that can fly is secured). Move vehicles to garage or away from trees. Take final pre-storm photos. Update family + emergency contacts on plan.
Post-storm: forensic inspection before any claim
Document damage from inside and ground-level. Do NOT climb onto a wet or wind-active roof. Call JDH for HAAG-certified inspection BEFORE filing any insurance claim. The inspection report with PCC Method findings determines whether a claim is approved or denied.

Maryland Hurricane Prep FAQ
Has Maryland ever had a major hurricane?+
Per the Maryland State Climatologist Office, only three hurricanes have directly hit Maryland since recording began in 1851: an unnamed Category 2 in October 1878, an unnamed Category 1 in 1893, and an unnamed Category 1 in 1933. Maryland has never had a major hurricane (Category 3 or higher) directly hit the state. What Maryland does get regularly: tropical storms, nor'easters, hurricane-remnant heavy rain (Isabel 2003, Sandy 2012, Isaias 2020), and the wind/rain damage from systems that pass by offshore or weaken to extratropical before arrival. Roof prep should target that pattern, not Florida-style Cat 5 prep.
When does Maryland's hurricane season start and end?+
Atlantic hurricane season runs June 1 through November 30 every year, with peak activity in August and September. For Maryland, the highest-risk window is late August through October when tropical systems are most likely to track up the Atlantic coast. The Maryland Department of the Environment recommends completing pre-season prep by June 1 and confirming readiness in late August.
What is the most important roof preparation for hurricane season in Maryland?+
A HAAG-certified pre-season inspection. The single highest-value action is identifying roof failure patterns (loose shingles, deteriorated flashing, ventilation deficiency, decking moisture) before high winds find them. JDH provides free pre-season inspections for Maryland homeowners; about 1 in 4 result in no recommended work. The next-highest-value action is clearing gutters and trimming branches within 10 feet of the roof - both contribute to most hurricane-season roof damage in Maryland.
What wind rating do Maryland roof shingles need to handle a hurricane?+
Per ASTM D7158, shingles are rated Class D (60 mph), Class G (110 mph), or Class H (150 mph). Maryland inland counties typically install Class D or G as code minimum. Coastal and bay-adjacent counties (Calvert, St. Mary's, Anne Arundel, parts of Charles, all of the Eastern Shore) should default to Class H, per FEMA P-804 wind retrofit guidance for coastal residential construction. JDH installs Class H as the default on all Southern Maryland coastal-adjacent installs. The upcharge is small relative to the storm protection delta, and insurance carriers in coastal counties often require Class H for full coverage.
Should I file an insurance claim immediately after a hurricane in Maryland?+
No. The correct order is: (1) document the damage with photos and timestamps; (2) get a HAAG-certified independent inspection BEFORE calling the carrier; (3) decide whether to file based on documented damage vs deductible math; (4) if filing, submit with the inspection report in hand. Filing without an independent inspection creates an adjuster record on a roof that may be wear-and-tear rather than storm damage, which often results in claim denial and policy non-renewal. See the storm damage insurance claims walkthrough for the full sequence.
How do I tarp a damaged roof safely after a Maryland storm?+
Do not climb onto a wet or wind-active roof - the National Weather Service consistently lists fall injuries as one of the top post-storm causes of injury. If active leaking is happening, place buckets inside, move furniture, and call a HAAG-certified inspector for emergency tarp placement. JDH offers same-day emergency tarp service in our Maryland service area during storm events. A temporary tarp installed safely from inside or by a certified inspector is far better than a tarp placed by a homeowner during active weather.
What's the difference between hurricane damage and wear-and-tear on a roof claim?+
Hurricane damage is storm-caused (impact damage, wind-lifted shingles with documented storm correlation, hail bruising matching event timing). Wear-and-tear is age-related (granule loss, sealant fatigue, ventilation deficiency, fastener back-out). Adjusters classify the same physical damage either way depending on documentation. A HAAG-certified PCC Method report (Problem - Cause - Consequence) on every finding is what separates a covered claim from a denial. The 'cause' column is where the storm correlation gets established or fails.
What outdoor items create the most hurricane risk for Maryland roofs?+
Tree branches within 10 feet of the roof are the single biggest cause of hurricane-season roof damage in Maryland. After branches: dead trees (especially mature oaks and pines weakened by lightning or insect damage), trampolines and patio umbrellas (become airborne), unsecured grills and propane tanks (impact damage + fire risk), and dish satellite mounts that age out and become projectiles. Pre-season tree trimming + securing outdoor items handles 70+ percent of the controllable risk.
