This post reflects the field reports of a GRS crew attending to a client's re-roofing request. At the onset, it would appear that they would like to explore Tough Roof or a liquid rubber system.
The homeowners at this location are in the midst of a complete remodel and are looking to eliminate all problems with their roof. Though smaller repairs could be made, it looks like they would like to replace the roof outright. After explaining the systems available to them, they appear most interested in Tough Roof or a liquid rubber system.
Scope of the Work:
Update (May 30, 2012)
- Sealants and tie-ins are dried, non-malleable, and cracking.
- The drainage appears to be good. No clogs, No pooling.
- The parapet walls consist of capping only.
- Building structure interior and exterior appear solid
- The current tar and gravel roof is splitting - there is no sponginess. Blistering was found in 2 areas, with the larger of the two nearly punctured.
- Christmas Light holders have been screwed into the capping above the windows, this will have to be replaced.
We advised the client that roof preparation would commence the following day for the engineered liquid rubber application.

Update (June 1st, 2012):
After picking up some equipment from another job, the crew arrived on site for 9:20am, ready to begin preparing the roof for liquid rubber application. The gravel had to be removed first, followed by a thorough power washing to remove all possible debris from the roof. This took up the bulk of the day, but they received some extra assistance between 3:30 and 5:30 from another pair of crew members after they'd completed another job. Everyone on the main team departed at 6:30pm.
The crew returned to the job site for ~10:00am and continued pressure washing the roof and preparing it for the spray-on liquid rubber. They departed again for 2:30, having completed the preparations. Liquid rubber was then applied to the roof in what is called a 'flood coat'. The crew cited that the single coat was appropriate, and that another wouldn't be necessary.
Update (June 13, 2012):
The client called us to advise that a leak had developed at the skylight and that regardless of rain quantity, it appeared 'random' in how much water would seep through, and at what rate. The leak began after the Christmas lights were removed from the screw-in fixtures atop the window capping. The responding team went back up onto the roof and determined that the caulking around the windows was correctly applied. They concluded that there was no damage to the roof or fault in the liquid rubber application; the leak must be a problem with the window itself.
Update (August 12, 2012)
The client reached out to us again that the window is continuing to leak, and that they would like us to look at the flashing on the roof where the Christmas lights had been screwed into. This recent bout of poor weather saw more water leaking in beyond a spot or two.
Update (August 28, 2012):
The crew made it out to the client's location for further, more extensive repairs and safeguarding. They arrived at 9:15, and removed water from the roof, blow drying it clear as well. The capping metal was replaced and screwed down, and a trowel installed to the roof connection. After that, they installed scrim sheeting just before more rain came in. They had to leave the site between 4:30 and 6:30pm due to weather, but returned to tarp the site walls for an over-spray of more liquid rubber. Another coat was started, and the team continued to work until 8:15pm when more rain came rolling in. Tarps were left in place with the client's blessing, and the team promised their return in the morning.
Update (September 19, 2012):
Once again, we arrived on location to address the area around the skylight/windows. Our crew member found a few holes and cracking that required repair. They were patched with seam tape and more liquid rubber. This repair took a mere hour and a half; crew departed site after that.
