Our Dallas-Fort Worth office, and where its roofs are.

Dallas is served from our Dallas-Fort Worth office at 1529 E IH 30 in Garland, 12 miles from the city’s center, on 214-937-5455.

For addresses that say Dallas, our AccuLynx records hold fewer than five job records and no finished jobs. Across Dallas-Fort Worth as a whole they hold 251 job records and 35 finished roofs, and most of those roofs are east and south of the city: 14 in Fate, 8 in McLendon-Chisholm and 8 in DeSoto. Nearly all of them were insurance jobs on homes, and most were finished between July and September 2026.

Two of those towns sat under the same storm. On April 27, 2026, spotters reported two-inch hail two miles southeast of Fate and at McLendon-Chisholm, and two inches in Rowlett the same day. By ZIP, the roofs cluster in 75032, which McLendon-Chisholm, Rockwall and Heath share, in 75189 around Royse City and Fate, and in 75115, which is almost all DeSoto. Our Dallas-Fort Worth job records go back to 2018, though most are from 2026, and the busiest months on file are July and August of that year.

North of the city, Allen has 17 job records and 7 finished jobs with us, and Fort Worth, served from the same Garland office, sits at the far end of the market. For leaks and storm damage inside the city, our Dallas roof repair page has the detail.

Your town. Your weather. Your roof.

Dated hail and wind reports logged near Dallas by trained spotters for the National Weather Service. Storm history is a reason to inspect, never a diagnosis.

Since September 18, 2023, trained spotters reporting to the National Weather Service logged 9 days with hail of 1 inch or more and 7 days with damaging wind within 10 miles of Dallas; the largest hail was 1.75 in on September 24, 2023. Storm history is a reason to inspect, never a diagnosis.

Tornadoes, hard wind, and bigger hail out in the metro.

From the National Weather Service’s spotter reports within ten miles of the city’s center point, and across the wider metro.

The ten miles around central Dallas logged 27 days of inch-or-larger hail and 29 days of damaging wind since September 18, 2016. In the ten years to September 2026, only three of the Dallas-Fort Worth towns on our site logged fewer hail days than Dallas, and Fort Worth logged clearly more. Inside the ten miles, the largest stones were two inches, northeast of Duncanville on April 9, 2021 and four miles west of Balch Springs on June 12, 2023, and 1.75-inch hail fell two miles south-southwest of the city the next day and three miles south-southeast on March 25, 2025.

In the city itself, the records that stand out are wind and tornadoes. On October 20, 2019, spotters reported tornadoes from north Dallas to west of Garland, one of them two miles from the city’s center point. Gusts of 75 to 78 mph were reported three miles west-northwest of Highland Park on March 2, 2023, May 28, 2024 and March 4, 2025, and 71 mph in Dallas twice in 2019. Out in the metro the stones get much bigger: five inches near Mansfield on June 12, 2023, three inches four miles west-southwest of Cockrell Hill on April 26, 2026, and hail of two inches or more within 30 miles of Dallas on 32 days in those ten years.

Wind like that can break the seal strips that hold shingles down without leaving a gap you can see from the street, and hail bruising rarely shows from the ground either; claims for both have time limits. The free Roof Grade test-squares every slope and dates the photos, and our storm damage repair page explains the claim. If you are replacing, price a Class 4 shingle, the UL 2218 rating for a 2-inch steel ball dropped from 20 feet: it is usually a few hundred dollars more on a typical roof, and many Texas insurers discount it.

Older houses, mostly rented, and a permit for nearly every re-roof.

The Census figures for the city and the City of Dallas’s own permit rule.

Dallas is an older city than most we serve: the Census Bureau puts the median build year of its 584,643 housing units at 1980, and owners live in just 42% of them, one of the lowest shares on our site. A house that old has outlived any asphalt roof by our cost guide’s numbers, 15 to 25 years for three-tab and 25 to 30 for architectural shingle, so the roof on it is likely its second or third, and many of those roofs are a landlord’s to replace. Our property manager program is built for owners with several.

The City of Dallas requires a permit for nearly every re-roof. Its published rule exempts re-roofing a single-family or duplex home only when the work is worth $500 or less, so a full replacement needs a re-roof permit, issued at the City’s district offices or online. We pull it for every Dallas replacement and handle the inspection that goes with it.

On houses this age, leaks usually start at the details our Dallas roof repair page walks through, from pipe boots to flashing and valleys. Where the roof is worn out, a roof replacement is the chance to put the attic ventilation right, and if you want the last roof the house will need, metal roofing in standing seam runs 40 to 70 years.

The prices we publish, and the permit inside them.

Nothing new here: these are figures our guides and repair page already carry.

Our cost guide is built on San Antonio-area jobs, and its yardstick is a 2,000 sq ft single-story home: roughly $8,000 to $13,000 in architectural shingle and $24,000 to $38,000 in standing seam or stone-coated steel. Per square foot installed, it gives $3.50 to $5.50 for shingle, $11 to $15 for metal and $10 to $20 for tile. A Dallas roof gets its own written number from the free Roof Grade.

The guide also says what belongs in the base price rather than an options list: the permit, tear-off, ice-and-water barrier, underlayment, boots, drip edge and ventilation. In Dallas, where nearly every re-roof needs a permit, look for that line on every bid.

Our roof repair page publishes typical repair prices too: a pipe boot or a few wind-damaged shingles typically $500 or less, chimney or wall flashing about $500 to $1,500. For storm damage, the wind and hail deductible on most Texas policies is a percentage of the amount the house is insured for, commonly 1% or 2%, and no roofer may legally cover it; our deductible guide shows when a claim makes sense.

Roofing questions in Dallas.

Ask your local team
Does Mammoth do metal roofing in Dallas?

Yes: standing seam, which lasts 40 to 70 years, and stone-coated steel, which carries a Class 4 rating and reads as shake or tile. Both install at $11 to $15 a square foot. If you may sell within ten years, our metal guide’s advice is that a Class 4 shingle is usually the better money.Metal vs asphalt

Where has Mammoth roofed in Dallas-Fort Worth?

Most of our finished Dallas-Fort Worth roofs so far are east and south of Dallas: 14 in Fate, 8 in McLendon-Chisholm and 8 in DeSoto. The Garland team that built them covers Dallas too, on 214-937-5455.

Did the April 2026 hail reach Dallas?

The biggest stones that week fell outside the city: three inches four miles west-southwest of Cockrell Hill on April 26, and two inches in Rowlett, Fate and McLendon-Chisholm on April 27. Within ten miles of the city’s center, spotters reported an inch to an inch and a half. If nobody has checked your roof since, the free Roof Grade looks at every slope.

Can wind damage a Dallas roof without hail?

Yes. Gusts of 75 to 78 mph were reported near Highland Park in 2023, 2024 and 2025. Wind breaks the seal strips that hold shingles down and lifts tabs, often without a gap you can see from the street, which is why the free Roof Grade checks every slope.

Do you handle roofs for Dallas landlords?

Yes. Most Dallas homes are rented, and our property manager program gives one call for every roof, scheduled inspections and a written report per property. The free Roof Grade and the written quote are the same as for any homeowner.Property manager program

Is the permit included in a Dallas roof quote?

It should be. Our cost guide lists the permit among the items that belong in the base price, and the City of Dallas requires one for nearly every re-roof. We pull it and handle the inspection.

What should I check before hiring a roofing contractor in Dallas?

Texas has no state license for roofers, so the checking is yours: the voluntary RCAT license, a workers’ compensation certificate with you named as holder, and a written scope that lists the permit the City of Dallas requires for nearly every re-roof. Our hiring guide has the full list.How to hire a roofer in Texas

Can a roofer waive my deductible in Texas?

No. Texas law prohibits a contractor from offering to waive, rebate or absorb a property-insurance deductible. Your insurer determines the coverage under your policy.Texas Department of Insurance

How often does hail hit Dallas?

Since September 18, 2023, National Weather Service spotter reports show 9 days with hail of 1 inch or more within 10 miles of Dallas and 34 such days within 30 miles. The largest hail logged nearby was 1.75 in on September 24, 2023. Over ten years (since September 18, 2016) the count is 27 days. Hail damage is time-limited for an insurance claim, so a dated inspection after a storm matters; the free Roof Grade gives you the photos and the written finding.

How far is the Mammoth office from Dallas?

About 12 miles. Dallas is covered from the Garland office at 1529 E IH 30, Suite 107, Garland, TX 75043; that team does the inspection and the work. Dallas sits in Dallas County.

How old are the homes in Dallas?

The Census Bureau's American Community Survey (2019–2023) puts the median build year of homes in Dallas at 1980, across 584,643 housing units, 42% of them owner-occupied. Mammoth's own guide treats 18 to 20 years as the point to plan a replacement for an asphalt shingle roof, so a home from that era is worth a written inspection.

Do I need a permit to replace my roof in Dallas?

In the City of Dallas, the published rule is this: Re-roofing a single-family or duplex home is exempt from a permit only when the work is worth $500 or less, so a full replacement needs a re-roof permit, issued at the district offices or online. (Dallas's own page, checked September 18, 2026.) Mammoth's local team confirms the current requirement for your address before work starts and files the permit when one is needed.City of Dallas Building Inspection FAQ
