Comparing Roofing Bids in Montgomery County, Ohio

A roof in Montgomery County can take hail strikes and wind uplift during a storm, and when it fails, the damage rarely stays confined to the shingles.

The southwest Ohio climate and your roofing

NOAA's Ohio state climate summary records that the Xenia tornado, rated F5, was part of the Super Outbreak of 1974. Xenia is in Greene County, in the Southwest division that also contains Montgomery County. The same summary calls the Great Flood of 1913 Ohio's greatest weather disaster, and it states that dangerous storms can occur in every season. It also lists snowstorms and ice storms as winter weather in Ohio.

Roofing issues to look for after a storm

• Decking and underlayment issues — discovered only at tear-off, and can be a source of change orders worth understanding in advance.
• Ventilation and code items — older roofs may need code-related upgrades; ask your contractor and your building department how local code items are handled.
• Slow leaks after a storm — minor damage can go unnoticed until water stains show indoors.
• Flashing and penetration damage — check chimneys, vents, and valleys, where post-storm leaks can start.
• Wind-lifted and creased shingles — broken seal strips let later storms drive rain under the roof surface.

What to expect locally

After a storm in Montgomery County, the useful work is slow: getting damage documented, raising questions with your insurer, and having the repair scoped carefully. Many homeowners find it helps to slow the process down at the start — documenting damage before tarps and repairs change the evidence, reading their policy before the first phone call, and getting more than one written bid before signing anything.

Local demand can also move in waves. After a widely publicized hail event, contractors across a region may get busy at once. If you receive more than one written bid, comparing them gives you a way to check pricing when demand spikes, and can surface scope differences — what one bidder saw that another missed — before the work starts rather than after.

Season and timing

Timing is worth planning. The weeks after a storm can be busy for adjusters and contractors, and winter weather can limit exterior work. Document the damage first, then take the time you need to compare any written bids you receive.

Montgomery County notes

Storm record for Montgomery County

NOAA's Storm Events Database logs 48 hail lines for Montgomery County across 17 calendar days. The earliest is April 26, 2016, the latest April 29, 2025, and 2026 has no hail line at all. Dates follow NOAA's records; its format guide says times are "usually in LST" (local standard time), and every Montgomery County row counted here is stamped EST. Twenty-six lines, falling on 10 of those days, record hail of one inch or more. Taylorsburg on June 18, 2021 carries the maximum, 1.75 inches. Four more lines sit a notch down at 1.50 inches: Beavertown (June 5, 2017), New Lebanon (April 3, 2018), Sulphur Grove (April 8, 2020) and Eastview (June 18, 2021). The Beavertown narrative says its size "was based on a photo from social media", and the Sulphur Grove narrative puts the hail near the intersection of OH-235 and I-70.

Two dates stand out from the rest. June 18, 2021 holds 11 lines labeled Beavertown, Clayton, Dayton, Drexel, Eastview, Ebenezer, Hempstead, Taylorsburg and Trotwood, and June 5, 2017 holds 8, labeled Beavertown, Clayton, Dayton, Englewood, Hempstead, Oak Ridge and "FT MC KINLEY". Add June 16, 2018 and you have every June date in this list, yet those three days supply 23 of the 48 lines; April, by contrast, spreads 16 lines over 7 days. By calendar year, 2021 is heaviest with 11 lines, all dated June 18.

Wind produces the longer list: 185 thunderstorm lines over 73 days, June 23, 2016 to May 19, 2026. A gust instrument is behind 23 of the lines and an estimate behind 162. June (61 lines, 16 days) and July (52 lines, 19 days) together supply 113. June 16, 2018 is the single busiest day at 13 lines, and June 18, 2025 comes next at 9. The highest figure is a 65-knot estimate under Eastview for March 30, 2025. The top instrument reading on record is 64 knots under Hempstead, also on March 30, and an airport row NOAA labels "(DAY)COX DAYTON INTL" shows 60-knot readings for April 1, 2023 and June 18, 2025.

Wind with no thunderstorm behind it goes into forecast-zone records instead. For this zone NOAA lists 11 High Wind lines, one per day, and 2 Strong Wind lines, also on separate days, from April 3, 2016 through March 15, 2026. The March 13, 2026 High Wind line gives 67 knots (about 77 mph), which its narrative says was "Measured at the Dayton airport (KDAY)." The same narrative gives a separate, lower reading from a second airport: "The ASOS at the Dayton-Wright Brothers Airport (KMGY) measured a gust to 61 mph."

Ten tornado lines fall on 6 days between March 14, 2016 and April 2, 2025. NOAA's format guide says its clock times are usually local standard time, and the Montgomery County rows counted here are stamped EST, an hour behind the wall clock when daylight time is in effect, so those times below carry both versions. The March 14, 2016 EF1, 2.98 miles in NOAA's length field, first touched down along Arlington Road just south of Sweet Potato Ridge Road. May 19, 2019 brings two EF1 lines, 3.96 and 0.97 miles long. May 27, 2019 brings four between 9:41 and 10:34 p.m. EST (10:41 to 11:34 p.m. daylight time): an EF4 labeled Pyrmont with an 18.17-mile length, the highest rating among Montgomery County's tornado lines; an EF2 labeled Eastview that starts in the Page Manor subdivision in Riverside and, NOAA says, was rated EF3 on its Greene County stretch; an EF0 that arrived from Miami County; and a second EF2, labeled Spanker, that began near Little York Road and Dog Leg Road south of I-70 and ran 7.57 miles. Next comes an EF1 of June 18, 2021, 2.04 miles from Puddenbag Road into Butler County, then an EF0 that began at 4:37 a.m. EST on February 28, 2024 next to Wright-Patterson Air Force Base. The final line, an EF0, crossed in from Warren County at 11:59 p.m. EST on April 2, 2025 (12:59 a.m. daylight time April 3) and ended near Nutt Road and Clyo Road. For 2026, NOAA's file dates from September 18, 2026, and the README beside it says that year's file gets rebuilt monthly, which means 2026 counts may change.

Housing stock

Census Bureau data for 2020 through 2024 (American Community Survey 5-year, table DP04) show 252,843 housing units in Montgomery County. Of these, 231,319 are occupied and 21,524 vacant (8.5 percent). Among occupied units, 144,482 are owned (62.5 percent) and 86,837 rented (37.5 percent).

Detached houses account for 170,413 units (67.4 percent) and attached houses for 17,967 (7.1 percent). Buildings of 3 or 4 units hold 16,394 (6.5 percent), buildings of 20 or more hold 13,987 (5.5 percent), and 3,238 units are mobile homes. Build dates peak in the 1970s with 43,305 units (17.1 percent), narrowly ahead of the 1960s at 42,422 and the 1950s at 42,257; 39,437 units (15.6 percent) are from 1939 or earlier and 18,602 from the 1940s. Summing the five bands gives 186,023 units from before 1980, or 73.6 percent, against 25,639 (10.1 percent) from the year 2000 forward. None of this reveals when a given roof was last replaced, so look up the date on yours.

Permits and local rules

Two kinds of office matter here. Montgomery County's Building Regulations Division, at 451 West Third Street in Dayton, says on its FAQ page that every township in the county falls under its jurisdiction and that some villages and cities contract with it for part or all of their enforcement. The same page warns that other jurisdictions, naming Dayton, Centerville and Kettering, "may have different requirements for contractor licensing or registration."

The county division's memo on roof coverings for shingle roofs, from its Chief Building Official and dated 10/09/2020, answers the permit question this way: "No permit is required for tear-offs and re-roofs that don't involve structural repairs, but they must still be installed in accordance with the provisions of the current Residential Code of Ohio (RCO), or the current Ohio Building Code (OBC)." Where the code table calls for it, the memo describes an ice barrier of "at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet" from the eave edge to a point at least 24 inches inside the exterior wall line, and it says existing layers must come off first where "the existing roof has two or more applications of any type of roof covering." The memo is dated 2020, so ask the division at 937-225-4622 whether it still stands.

Inside the City of Dayton, the Building Inspection Division's FAQ poses "Do I need a permit to install or re-roof my house?" and replies "If you are simply applying a new layer of shingles you do not need a building permit", while replacing or repairing any of the wood sheathing under the shingles, or the rafters or trusses, does require one. It adds that you "might need to obtain a Certificate of Appropriateness (COA) if your home is located in a historic district." The division says it manages a registration program for "plumbing, mechanical and electric contractors", and its registration forms and lists cover electrical, pipe-laying, plumbing and warm air heating contractors, not roofing, so ask the division at 937-333-3883 how a roofer is treated. The county FAQ says state licensing is not required for "contractors that only do 1, 2, 3 Family Residential work."

What to line up before you ask for bids

- Your insurer's written estimate, if you hold one, kept where every bidder can read it.

- Whether your address falls under the county division, the City of Dayton or another city's building office, since the rules above differ between them.

- A note of whether the roof deck or rafters need repair, because both offices tie a permit to structural work, and a question to each bidder about how its bid handles that.
