The following photos and text take you through iTech's initial inspection of the roof, examines the specific problems iTech encountered with the existing roof, and details how iTech solved this roof's problems.

Princeton, Indiana |
| Job Scope: |
|
Shopping Mall - 120,000 sq ft out of 550,000 contract on five malls from Reading, PA to Princeton, IN |
| Type of Roofing: |
|
Ballasted EPDM Rubber Roof and Fully Adhered EPDM Rubber |
Many shopping malls have this type of roofing system installed on their roofs right now.
|
| What happened here is simple, the installer didn't ensure a 7” fastener screw was drilled into solid decking. Over time, and after the labor warranty expired, the problem finally showed up. |
|
 |
|
|
|
This roof system did not have a way to install the flashing details needed to counter the black roof pulling so much.
On this site, the EPDM rubber pulled right off the walls. |

| Seams |
|
|
|
| This seam looked like it was sealed, but it wasn't. |
|
 |
|
|
|
It does not do any good to just run another bead of caulking without the proper preparation work.
And a new rubber bead is just a band-aid that will pull apart in a short time. |

| Under Rubber Damage |
|
|
|
This plug was not taken next to the above seams, but was taken several feet away and uphill at that.
Roof leakage is not seen until the damaged has already occurred. |
|
 |
|
|
|
| The worst thing about this roof was iTech’s Roof Maintenance Service could have prevented this section of the roof from having to be torn off and replaced, thereby saving the owners $2.50 per square foot over a ten year period. |

|
| Flashing on a Ballasted EPDM Rubber Roof |
|
|
|
| When a roof has so much pull that it can move hundreds of pounds of rock around on a roof, the flashings are bound to pull away from the walls. |
|
 |
|
|
|
| This roof moved the flashings so much that over time as it got old, even the rubber pulled apart. |
