Roof leak remediation leaving in place saturated material
Roof-on-roof methods of leak remediation leave in place existing roof membrane material and saturated material (e.g., insulation). An example leak-remediated roof includes a layer of saturated insulation over a roof deck. A membrane over the insulation has one or more failures that have permitted the insulation to become saturated. A grid of cuts is made through the membrane and the insulation down to the roof deck. A mechanical vent is placed over a cut of the grid A strip of mesh vent is installed over a cut of the grid. The strip of mesh vent is coupled in airflow communication with an underside inlet or a lateral inlet of the mechanical vent. A non-liquid sealer, such as tape or covering membrane, seals over the strip of mesh vent. A liquid roof coating is applied over an entire surface of a treated portion of the roof, including over the non-liquid sealer.
1. A method of roof leak remediation comprising:
cutting a grid of cuts through a membrane of a roof, through saturated material of the roof under the membrane, and to a deck of the roof;
installing a mechanical vent over a cut of the grid of cuts;
installing a vent strip over a cut of the grid of cuts, the vent strip in airflow communication with an inlet of the mechanical vent;
sealing over the vent strip with non-liquid sealer; and
applying a liquid roof coating over a treated portion of the roof, including over the non-liquid sealer.
2. The method of claim 1 , wherein the mechanical vent is installed over an intersection of two or more cuts of the grid of cuts.
3. The method of claim 1 , wherein:
the installing the vent strip is subsequent to the installing the mechanical vent;
the mechanical vent is installed on the membrane; and
the vent strip is installed to be in airflow communication with a lateral inlet of the mechanical vent.
4. The method of claim 1 , wherein:
the installing the mechanical vent is subsequent to the installing the vent strip;
the mechanical vent is installed on the vent strip; and
the vent strip is installed to be in airflow communication with an underside inlet of the mechanical vent.
5. The method of claim 1 , wherein parallel cuts of the grid of cuts are spaced apart from each other by no more than about ten feet.
6. The method of claim 1 , wherein no cut of the grid of cuts is closer than five feet to an outer perimeter of the roof.
7. The method of claim 1 , further comprising cutting a core cut at one or more intersections of cuts in the grid of cuts.
8. The method of claim 1 , wherein the mechanical vent is a wind-driven turbine vent.
9. The method of claim 1 , wherein the mechanical vent is an electrically driven vent or a solar-powered electrically driven vent.
10. The method of claim 1 , wherein the vent strip is a strip of mesh vent.
11. The method of claim 1 , wherein the non-liquid sealer comprises adhesive roofing tape or pieces of thermoplastic polyolefin (TPO) or ethylene propylene diene monomer (EPDM) membrane.
12. A method of roof leak remediation comprising:
cutting a grid of cuts through a membrane above a roof deck and through saturated material of the roof under the membrane;
installing vent strips over cuts of the grid;
installing mechanical vents over cuts of the grid; and
sealing over the vent strips with non-liquid sealer.
13. The method of claim 12 , wherein at least one of the mechanical vents is installed over an intersection of two or more cuts of the grid of cuts.
14. The method of claim 13 , wherein parallel cuts of the grid of cuts are spaced apart from each other by no more than about ten feet.
15. The method of claim 14 , wherein no cut of the grid of cuts is closer than five feet to an outer perimeter of the roof.
16. The method of claim 13 , further comprising cutting a core cut at one or more intersections of cuts in the grid of cuts.
17. The method of claim 12 , wherein at least one of the mechanical vents is a wind-driven turbine vent.
18. The method of claim 12 , wherein the non-liquid sealer comprises adhesive roofing tape or pieces of thermoplastic polyolefin (TPO) or ethylene propylene diene monomer (EPDM) membrane.
19. A leak-remediated roof comprising:
a solid roof deck;
a layer of saturated material over the roof deck;
a membrane over the layer of saturated material having one or more failures allowing liquid to engage the saturated material;
a grid of cuts extending through the membrane and the saturated material down to the roof deck;
a mechanical vent over at least one cut of the grid of cuts;
a vent strip over at least one cut of the grid of cuts, the vent strip in airflow communication with an underside inlet or a lateral inlet of the mechanical vent;
a non-liquid sealer sealing over the vent strip; and
a liquid applied roof coating over a treated portion of the roof, the treated portion of the roof including the non-liquid sealer.
20. The roof of claim 19 , wherein the mechanical vent is over an intersection of two or more cuts of the grid of cuts.
