Dallas County holds the oldest and the densest of the metroplex's housing, and it also holds some of the widest variation in permit rules of anywhere in North Texas. The county does not decide any of it. The city the address sits in does, and the cities here do not agree with each other.

What is different here
Three things that decide how a roof job goes in this city, and that are not the same one town over.
Inside city limits, the city does — not Dallas County. Each city in the county publishes its own roofing permit rule, and in this metroplex those rules genuinely differ from one another. The county's own permitting applies to unincorporated land, so for an address inside any city limit it is the city's rule that governs and the city's inspector who attends.
Within Dallas County we cover Dallas, Garland, Richardson, Irving, Grand Prairie and Coppell. Two of those are untidy on the map: Grand Prairie extends into Tarrant and Ellis counties, and Coppell extends into Denton County. Both are permitted by their own city regardless of which county a given lot falls in.
Dallas Central Appraisal District holds the property record for every address in the county, including those in Garland, Irving and Richardson, which run their own permitting entirely separately. So the appraisal record and the permit history for one house live in two different places, under two different authorities, and neither describes the roof's condition.
Local context
This is the county with the longest span of building dates. Pre-war frame and brick near the centre with steep pitches and later rear additions; large post-war one-storey ranches through Garland, Richardson and Irving with long, shallow planes; and newer, taller and more cut-up plans further out. A roof here can be on its first covering or its fourth, and the difference is usually visible from the driveway before anyone gets on a ladder.
Layers, and what is under them. On the older houses a replacement is as likely to be a question about the deck as about the covering, because a roof that has been recovered rather than torn off more than once hides what is beneath it. That is the thing an assessment tries to establish before a scope is priced, and it is also the thing that most often changes a scope once the tear-off starts.
Several cities in this metroplex sit across a county boundary, and a few sit across three. It changes nothing about who permits the work — that follows the city limits, not the county — but it does change which appraisal district holds the property record, and it is a common source of confusion when someone is trying to find out what is on file about a house. If an address is near a line, check the city first: the city is the one that will inspect the roof.
Questions
Because each city adopts and administers its own building code and its own permitting process, and they do it on their own timetable. Being in the same county creates no shared rule at all. Garland's re-roofing guidance asks for either the executed contract or the adjuster's scope with the application, which is not something Dallas asks for. Read the rule for the city on the deed, not the one for the city you shop in.
At the city, not the county. Each city here runs its own permitting system and publishes its own search, so the record lives in whichever municipal system covers the address — and where a property is near a boundary, establishing which city that is comes first. The county holds the appraisal record, which is a different document maintained for a different purpose and does not carry permits.
Less than people expect, and less in this county than almost anywhere else in the region. Dallas County holds the longest span of building dates in the metroplex, so two houses on the same street can be sixty years apart, and either of them may be on its first covering or its fourth. What the year of construction gives you is a floor: the roof cannot predate the house. Everything more precise comes from the covering itself.
Not if the property is inside a city. The city that the address belongs to runs the inspection, under whatever code cycle that city has adopted, and two neighbouring cities in this county can be on different cycles. County inspection applies to unincorporated land. The seat of Dallas County is Dallas, and that is an administrative fact rather than a routing instruction — do not send a permit question there because a property is in the county.
Assessment request
Short, routing-only questions. Nothing here asks you to diagnose the roof yourself.
