There should be no permits required for a roof tripod or small tower in most areas of Dallas. Just need grounding to code and there is no permit or inspection for that. You will be better off grounding wise if the tripod/tower is within about 30ft of your AC entry panel. If you catch me in town for any length of time I would just do it for you but I'm not sure when I'll be back in the area.
Here are some excerpts from the Dallas City Code that lists some districts where towers are not permitted. You might see if you are in one of those districts.
- The Dallas City Code
- SEC. 51A-4.217. ACCESSORY USES
(7) Amateur communication tower.
(A) Definition: A tower with an antenna that transmits amateur radio, citizen band, or both spectrums, or that receives any portion of a radio spectrum.

(ii) An SUP is required for this accessory use in MF-3(A) and MF-4(A) districts.
(C) Required off-street parking: None.
(D) Required off-street loading: None.
(E) Additional provisions:
(i) In all districts where this accessory use is permitted except MF-3(A) and MF-4(A) districts, a person may erect one amateur communication tower that exceeds the maximum height specified in Section
51A-4.408 if the amateur communication tower:
(aa) does not exceed 60 feet in height;
(bb) is setback an additional 12 inches from the required front, side, and rear yards for each additional eighteen inches of height above the maximum height specified in Section
51A-4.408;
(cc) has a maximum horizontal cross-sectional area of three square feet;
(dd) has no more than two antennae above the maximum height specified in Section
51A-4.408 with a maximum volume of 900 cubic feet for a single antenna and 1400 cubic feet for two antennae. In this provision, antenna volume is the space within an imaginary rectangular prism which contains all extremities of the antenna;
(ee) does not encroach into the required front, side, or rear yard. A guy wire and anchor point for a tower is prohibited in the required front yard and is also prohibited in the required side and rear yards unless the guy wire and anchor point is attached to the top of a structural support that is no less than six feet in height. If a structural support for a guy wire and anchor point is used, the structural support may project into the required side and rear yards no more than two feet, measured from the setback line. In this provision, a structural support for an anchor point is any pole, post, strut, or other fixture or framework necessary to hold and secure an anchor point or within three feet of the side or rear property line. If an alley abuts a rear property line, a guy wire and anchor point may extend to the rear property line; and
(ff) has a minimum space between antennae above the maximum height specified in Section
51A-4.408 of eight feet or more as measured vertically between the highest point of the lower antenna and the lowest point of the higher antenna.
(ii) The board of adjustment may allow a special exception from the requirements of Subsection (E)(i) with the exception of Subsection (E)(i)(aa), if the board finds that the special exception would not adversely affect neighboring property and would be in harmony with the general purpose and intent of this section.
(iii) In all residential districts where this accessory use is permitted except MF-3(A) and MF-4(A) districts, a person may erect an amateur communication tower over 60 feet and not above 100 feet in height if authorized by a specific use permit.
(iv) This accessory use may occupy up to 25 percent of the area of the lot containing the main use.
(v) This accessory use is prohibited in all residential districts in the area between the street and the facade of any main or accessory structure. (This area includes, but may be greater than, the front yard.)
(vi) The owner or operator of an amateur communication tower shall remove the tower within six months of the date that the tower ceased to operate as an amateur radio, citizen band, or radio spectrum authorized by the Federal Communications Commission. Upon failure of the owner or operator to remove the tower within the prescribed period, the building official shall notify the city attorney to pursue enforcement remedies against that owner or operator for failure to remove the tower.
