Cedar Hill requires full gutter drains on all portions of every roof — a rule the city wrote itself that exists in no model code. If a bid has no gutter line on it, it was not written for this city.
Cedar Hill has a roofing rule that exists nowhere in the model code and nowhere in the regional amendments. Section 4-352(29) of the city code amends IRC R903.4 to read: roofs shall have full gutter drains on all portions of roofs, and the discharge shall not be directed at neighboring properties. That is a Cedar Hill original. Gutters are not optional here and they are not an upsell. If a bid on your kitchen table has no gutter line on it, the person who wrote it does not know this city.
There is a second local choice that matters. When the North Central Texas Council of Governments rewrote R902.1 for the region, it struck the blanket requirement that Class A, B or C roofing be installed and narrowed it to roofs designated by law or within three feet of a lot line. Most cities around here took that relaxation. Cedar Hill did not. Its adopted R902.1 keeps the mandatory sentence, so every roof covering on a dwelling in Cedar Hill must carry a Class A, B or C fire rating, with non-classified coverings permitted only on detached sheds and playhouses under 240 square feet. The practical effect is that untreated wood shakes, which carry no classification, cannot go on a Cedar Hill house.
The weather here is the most severe in this part of Dallas County. Within ten miles of the city center the record holds 22 hail events of two inches or larger since 2010, the highest severe-hail density of any city on this side of the county. On the night of June 12, 2023, a social media photo showed a four-inch stone near Cedar Hill, with baseball-sized hail near Cedar Hill State Park, measured tennis-ball hail two miles west of town, and a five-inch stone over in Mansfield. NOAA logged at least $4.3 million in property damage within ten miles of Cedar Hill inside about thirty minutes that night. The NWS explanation for that week is worth reading: a late spring cold front pushed south and became stationary near the I-20 corridor, then meandered there for days while upper-level disturbances fired storms over the same ground. Cedar Hill sits right on it.
That is also why Cedar Hill's hail season runs a month later than its neighbors'. June is its single biggest month, which is unusual for North Texas and the opposite of what most homeowners expect. On April 26, 2017 a trained spotter reported hen-egg hail inside the city before five in the morning. On March 4, 2025 emergency management reported that multiple homes in the Stone Hill neighborhood sustained damage to roofs, fences and street signs. And back on June 13, 2012, the second of the two supercells that caused over a billion dollars of hail damage in Dallas County tracked from Irving straight into Cedar Hill.
Worth saying plainly: no tornado has been logged within five miles of Cedar Hill's center since 2010. Hail and straight-line wind are this city's story, not tornadoes.
The terrain is a real factor and it is measurable. Cedar Hill sits at the northern edge of the Balcones Escarpment, and elevation across the city footprint runs from roughly 520 feet to 848 feet — about 330 feet of vertical relief inside one small city. The city has a codified escarpment development ordinance dating to 1994 that defines the escarpment zone by the contact line between the Austin chalk and the Eagle Ford shale, and requires a slope stability factor of safety of at least 1.5 for any structure, cut or fill. A roof replacement does not trigger that plan; a large addition on an escarpment lot does. But the shale itself shows up in everyday work here — the city publishes standing Eagle Ford Shale foundation requirements, and foundation movement is what puts many Cedar Hill roofs out of plane in the first place.
The housing stock is the largest of the cities around here at 17,499 units, with median year built 1995 and two clear build booms: 4,518 homes in the 1980s and 4,613 in the 2000s. Median home value is $302,700 and 82 percent of the stock is single-family detached. Those 1980s homes are on a third or fourth roof now.
Permits: a residential roof permit is $100 and reinspection is $50. Cedar Hill requires a permit for any construction, alteration or repair of any structure, roofing, exterior doors or windows, building or building system — roofing is named explicitly. Inspection requests must be in before 4 pm the day before. General contractor registration is $100 a year and every registration expires December 31 regardless of when it was issued, so a roofer who registered in November has six weeks on it.
Two more local specifics. Cedar Hill deleted the model code's exemption for small detached accessory structures, so even a shed needs a permit here. And every permit application in the Lake Ridge subdivision requires a detailed lot grading plan sealed by a Texas registered professional engineer — one named neighborhood, written into citywide code.

View Roof Maintenance →Cedar Hill amended IRC R903.4 to require full gutter drains on all portions of roofs, with discharge that does not aim at your neighbor's property. That language exists in no model code and in no regional amendment set; the city wrote it. We quote gutters as part of a Cedar Hill re-roof rather than as an add-on, and we plan the discharge so it does not become a neighbor problem or a foundation problem on an escarpment lot.
When the region relaxed R902.1 to require Class A, B or C roofing only near lot lines, Cedar Hill kept the blanket requirement. So every dwelling roof in this city must carry a classification, and non-classified coverings are allowed only on detached sheds under 240 square feet. Untreated wood shakes carry no classification and therefore cannot go on a Cedar Hill house. It is a small distinction in the text and a firm one in practice.
Cedar Hill runs about 330 feet of vertical relief across a small footprint, sitting on Austin chalk over Eagle Ford shale. The city publishes standing Eagle Ford Shale foundation requirements because movement here is routine rather than exceptional. Foundation movement is what puts a roof out of plane, opens ridge lines and splits flashing, so on older Cedar Hill houses we look at what the structure is doing before we blame the shingles.

Yes. The city amended IRC R903.4 to state that roofs shall have full gutter drains on all portions of roofs, and that the discharge shall not be directed at neighboring properties and shall discharge on the property or another approved location. This is a Cedar Hill original, not a regional requirement, and it is the single most commonly missed item in bids written by contractors who work the whole Metroplex.
Not untreated ones. Cedar Hill's adopted R902.1 requires Class A, B or C roofing on dwellings without the lot-line qualifier that most neighboring cities adopted, and permits non-classified coverings only on one-story detached accessory structures under 240 square feet. Untreated wood shakes are non-classified, so they do not meet the requirement. There is no ordinance naming wood shakes specifically; the classification rule is what does the work.
One hundred dollars for a residential roof, with a $50 reinspection fee, and general contractor registration at $100 a year expiring every December 31. We will note honestly that the fee ordinance the city publishes as its current schedule ends with a blank, unsigned adoption block and carries no adoption date, so we confirm figures with Building Inspections at 972-291-5100 before quoting them as final.
Later than you think. June is Cedar Hill's single biggest hail month, which is unusual for North Texas and about a month behind its neighbors. The reason is geographic: NWS summaries describe cold fronts pushing south and stalling near the I-20 corridor, then firing storms over the same ground for days. Cedar Hill sits right on that line. The June 12, 2023 night produced a four-inch stone near town and at least $4.3 million in logged damage within ten miles.
Less than you might, and we would rather give you the real number. No tornado has been logged within five miles of Cedar Hill's center since 2010, though the ten-mile ring picks up ten. What Cedar Hill gets is hail and straight-line wind: 22 separate events of two inches or larger inside ten miles since 2010, and a March 2025 report of multiple homes in the Stone Hill neighborhood with roof, fence and sign damage.
No. The city's own fill-in of IRC Table R301.2(1) lists ice barrier underlayment as not required, sets design wind speed at 115 mph three-second gust and ground snow load at 5 pounds per square foot. Cedar Hill did not amend R905 or R908 at all, so underlayment, drip edge, fastening and layer rules run on the unmodified 2021 IRC. The two things Cedar Hill did write for itself are the gutter rule and the roof classification rule.
For a roof, no. But it is worth knowing that Cedar Hill wrote your subdivision into citywide code: all permit applications in the Lake Ridge subdivision require a detailed lot grading plan with existing and proposed grades, sealed by a Texas registered professional engineer, plus a precise grade survey at final inspection. That applies to permits generally rather than to roofing specifically, and it is the kind of thing that catches people on an addition.
