Where hail falls in Maryland
Hail in Maryland mostly comes with spring and summer thunderstorms, and the central and western counties see the bulk of it. Frederick, Washington, Carroll, Baltimore and Montgomery counties all have neighborhoods where several storms have crossed in a few years. Because hail paths are narrow, one street can have bruised shingles and dented gutters while the next is untouched – which is why the carrier’s weather report and your roof can tell different stories.
Wind is the other half of most roof claims. Thunderstorm gusts, derechos and nor’easters lift tabs, break seals and peel ridge caps. Our windstorm and tornado appraisal page covers wind events in more depth.
Roof types that drive disputes
Architectural asphalt shingles
The most common roof on suburban Maryland homes. The usual argument is whether hail fractured the mat or simply knocked off granules, and whether the shingle line is still made. If the product has been discontinued, a repair may leave a patch that doesn’t match in color, profile or dimension.
Slate in historic districts
Annapolis, Frederick and older parts of Baltimore have slate roofs that can last generations. Repairs need matching slate, copper flashing and skilled labor, and historic district rules may limit what substitutes are acceptable. Pricing slate work as if it were asphalt is one of the biggest gaps we see.
Rowhouse low-slope roofs
Baltimore rowhouses typically have membrane or built-up roofs with parapets and flashing tied to the neighbors’ roofs. Ponding, punctures and seam failures after a storm often mean replacing a full section, and the work has to be coordinated with adjoining owners. See our guide to rowhouse roof claims.
Standing-seam and exposed-fastener metal
Common on farm buildings and some newer homes. The question is often whether denting is purely cosmetic and whether the policy has a cosmetic-damage limitation.
The repair-versus-replace argument
Most roof appraisals turn on whether the damage can be fixed in isolated spots or the roof needs replacement. We document the facts a panel needs to decide:
- Hit counts on each slope using a consistent test area, plus soft-metal damage on vents, gutters and flashing.
- Brittleness and repairability – whether shingles or slates can be lifted and replaced without breaking neighbors.
- Product availability and whether a repair can reasonably match.
- Measured squares, pitch, waste, layers to remove and starter and ridge lengths.
- Code items such as drip edge, ice-and-water underlayment and ventilation that a full replacement would require.
Our roof square and pitch calculator lets you sanity-check the quantities in the carrier’s estimate before you decide anything.
Line items that often go missing
- Steep-roof and high-roof labor charges on two- and three-story homes.
- Tear-off of more than one layer.
- Gutter and downspout replacement where dents affect function or match.
- Skylight flashing kits, chimney counter-flashing and pipe boots.
- Interior ceiling repairs where leaks followed the storm.
Maryland Insurance Appraiser prices roofs at local rates for your county and roof type. If the panel is going to decide your roof, it should be deciding it on measured, photographed facts rather than a drive-by estimate.
Before you sign a contract or demand appraisal
Keep the roofer’s inspection photos, the carrier’s estimate and any engineer or ladder-assist report together. Note the date of the storm and when you first saw damage, and write down every conversation with the adjuster. If the carrier approved only part of the roof, ask in writing which slopes were excluded and why. That paper trail is what lets an appraiser reconstruct the disagreement accurately, and it often shows that the gap is about measurements and matching rather than about whether hail hit the house at all. A storm that crossed Hagerstown or Westminster last spring can still be documented months later if the record is kept.
Questions about roof & hail damage appraisal
Can appraisal force my insurer to replace the whole roof?
Appraisal sets the amount of loss, and in many Maryland roof disputes that amount reflects whether repair is feasible or full replacement is needed. Whether the damage is covered at all remains a coverage question outside appraisal.
What if my shingles are discontinued and a repair won’t match?
Matching is a common valuation issue. An appraiser documents the product, the availability of replacements and how a mismatch would look, so the panel can decide how much of the roof must be replaced for a reasonable repair.
Are slate roofs in Annapolis or Frederick harder to appraise?
They require specialized pricing for matching slate, copper flashing and skilled labor, and historic district rules can affect materials. Those costs are often missing from standard carrier estimates.
