Systems and methods for drying roofs

1. A system for drying a roof structure, comprising:

an extraction insert having at least one entrance opening positioned in the extraction insert to receive a flow of moist air from within the roof structure, and at least one exit opening positioned in the extraction insert to deliver the flow of moist air;

an injection insert having at least one entrance opening positioned in the injection insert to receive a flow of dry air and at least one exit opening positioned in the injection insert to deliver the flow of dry air to the roof structure; and

a retainer positioned to secure a cover to the roof structure, wherein the extraction insert extends through the retainer.

2. The system of claim 1 , wherein the cover is positioned over the injection insert to form a plenum below the cover and above a surface of the roof structure.

3. A system for drying a roof structure, comprising:

an extraction insert having at least one entrance opening positioned in the extraction insert to receive a flow of moist air from within the roof structure, and at least one exit opening positioned in the extraction insert to deliver the flow of moist air;

an injection insert having at least one entrance opening positioned in the injection insert to receive a flow of dry air and at least one exit opening positioned in the injection insert to deliver the flow of dry air to the roof structure; and

a retainer positionable to secure a cover to the roof structure, wherein the injection insert has a first body having first spreadable portions, and wherein the extraction insert includes a second body having multiple second spreadable portions.

4. A method for drying a roof structure, comprising:

placing a cover over multiple injection inserts in the roof structure, wherein the cover is secured to the roof structure with a retainer, and wherein at least one of the multiple injection inserts is positioned through a hole in the retainer;

directing a flow of air into a plenum between the cover and the roof structure via an air mover;

directing moisture-laden air from within the roof structure to a dehumidifier to produce dried air;

directing at least some of the dried air into the roof structure through at least one of the multiple injection inserts; and

balancing the first flow volume passing through the air mover and the second flow volume passing through the dehumidifier.

5. The method of claim 4 , further comprising coupling the dehumidifier to at least one of the plenum and a manifold coupled to the air mover.

6. The method of claim 4 , further comprising directing the at least some of the dried air into the roof structure via a plenum between the cover and the roof structure.

7. The method of claim 6 , further comprising heating the plenum with solar radiation absorbed by the cover.

8. A method for drying a roof structure, comprising:

activating an air mover to remove moisture-laden air from within the roof structure through an extraction insert;

directing the moisture-laden air to a dehumidifier to produce dried air;

directing at least some of the dried air into the roof structure through an injection insert, wherein a cover is placed over the injection insert and is secured to the roof structure with a retainer, and wherein the injection insert is positioned through a hole in the retainer;

balancing a first flow volume passing through the air mover and a second flow volume passing through the dehumidifier.

9. The method of claim 8 , further comprising adjusting a position of the injection insert inside the roof structure so as to selectively direct air to at least one of a corrugated steel layer of the roof structure, an insulation layer of the roof structure, and a fiber board layer of the roof structure.

10. The method of claim 8 , further comprising:

measuring a moisture level of the moisture-laden air and the dried air;

removing the injection insert and the extraction insert from the roof structure in response to the moisture level of the moisture-laden air being lower than a threshold level; and

applying a sealant to the roof structure after removing the injection insert and the extraction insert from the roof structure.

11. The method of claim 8 , further comprising:

measuring the first flow volume passing through the air mover;

measuring the second flow volume passing through the dehumidifier; and

balancing the first flow volume and the second flow volume at least partially based on an ambient temperature determined by a temperature sensor.

12. The method of claim 8 , further comprising coupling a water separator to be in fluid communication with the extraction insert, and separating water from a flow of fluid removed from within the roof structure by the air mover.

13. The method of claim 8 , further comprising removing water vapor from the moisture-laden air.

14. The method of claim 13 , further comprising coupling the dehumidifier in fluid communication with the injection insert to direct air to the injection insert.

15. The method of claim 8 further comprising positioning the extraction insert in a fiber board layer of the roof structure by passing a portion of the extraction insert through a membrane layer of the roof structure.

16. The method of claim 8 , further comprising:

placing the cover over the injection insert to form a plenum in fluid communication with the injection insert; and

directing air into the roof structure via the injection insert and the plenum.
