Sensing roofing system and method thereof

A system, comprising:

• a roof deck of a steep slope roof of a structure;
• a flexible underlayment installed on the roof deck,
• wherein the flexible underlayment comprises:
• a first layer,
• a first sensor integral with the first layer,
• wherein the first sensor comprises a first flexible circuit, and
• wherein the first flexible circuit is configured to:
• measure a first value representative of a first roofing system condition,
• wherein the first flexible circuit measures the first value at a first location,
• wherein a first location identifier indicative of the first location is stored in a database in communication with the first sensor,
• determine the first roofing system condition in the first location based at least in part on the first value and the first location identifier, and
• generate a first notification representative of the first roofing system condition in the first location;
• and
• a second sensor integral with the first layer,
• wherein the second sensor comprises a second flexible circuit, and
• wherein the second flexible circuit is configured to:
• measure a second value representative of a second roofing system condition,
• wherein the second flexible circuit measures the second value at a second location,
• wherein the second location is different from the first location,
• wherein a second location identifier indicative of the second location is stored in the database in communication with the second sensor,
• determine the second roofing system condition in the second location based at least in part on the second value and the second location identifier, and
• generate a second notification representative of the second roofing system condition in the second location;
• a first roofing shingle installed on the flexible underlayment,
• wherein the first roofing shingle is disposed above at least the first sensor;
• and
• a second roofing shingle installed on the flexible underlayment,
• wherein the second roofing shingle is disposed above at least the second sensor,
• wherein at least one of the first roofing shingle and the second roofing shingle comprises a photovoltaic module.
