[Update] LOA reached out to me after seeing my complaint. They acknowledged that the placement of…read morethe scuppers could have been handled better and agreed to issue a refund for the gutter installation. In addition, they assured me that they would send someone to inspect the ponding water if the issue worsens during next year's rainy season. I appreciate that they took customer feedback seriously, and as a result, I've updated my rating from 3 stars to 5 stars.
Context: I recently bought a house with a flat roof. This flat roof has 3 major areas. Because the original roof was poorly done, I decided to replace 2 parts of the 3. I hired LOA to install a 135mil TPO roof for this residential house. They came and installed the TPO from October 21 to 25, 2025. The total project costed $18,280. As I just bought the house, I paid the full amount out of my own pocket. My experience with LOA was a bit mixed.
I will start from the positive side. Their price was competitive. I got 3 roofers to give me quotes for 80mil TPO and all had great reviews on both Yelp and Google. The highest quote was around $24K and the lowest one was around $16k. LOA's original quote ($16680) was in the middle but was very similar to the lowest one. Additionally, their sales representative was very responsive and helpful and that was one major reason why I chose LOA over the lowest one. After I decided to hire LOA, they even offered me 135mil if I added $1K because they had some leftover 135mil from another commercial project and I decided to take it. Basically the experience before the actual installation started was very positive.
However, after the installation actually got started, the experience was mixed. First of all, they changed the crew just a couple of days before the installation because LOA got a big commercial project and that crew was assigned to that commercial project. But they told me the new crew was also experienced and ensured that I didn't need to worry about it. But what happened next didn't seem to show the new crew was that competent -- Initially I was told the whole installation would take 1 day, but in fact, it took the crew 5 days to complete. For me, taking longer time to complete the installation was not a big issue because I'd rather them do it right. Later they told me one of the reasons why the new crew spent so much time was because the new crew actually replaced all 3 parts of the roof rather than just 2 parts. This was a nice surprise since they didn't charge me more for that. But apparently there was a communication issue between LOA and the crew. Additionally, because of the installation delay, the weather changed and we got a bit of rain before the installation was fully completed, but they told me the roof was mechanically sealed so I didn't need to worry about the rain during the installation.
When the rain actually came after the entire roof was installed, that was when the problems began. The first problem was the placement of the scuppers: two of them were positioned right above my wooden deck. Whenever it rained, water poured straight onto the deck. After I complained, LOA explained that the original roof had been designed that way. Although they could have positioned the scuppers in different places, they said they simply followed the original design since I hadn't specifically asked for changes. I found this frustrating -- I'm not a professional roofer and as a new homeowner I expected them to use their expertise to warn me about potential issues like this in advance. Unfortunately, they didn't consider the bigger picture when installing the roof. Anyway, as I felt I couldn't entirely blame LOA, I decided to spend additional $600 for them to install a gutter to redirect the water away from the deck.
The second problem was ponding water. Even 36 hours after the rain had stopped, I could still see standing waters in at least 3 areas of the roof. One of these spots (number 1 in the photo) was exactly where the original roof had issues. Even worse, two of the ponding areas (number 1 and 2 in the photo) were located on the seams. I raised this concern with LOA again, but they said they wouldn't worry unless the waster remained for more than 4 days -- despite the fact that information from other roofers' websites suggests ponding water could be a concern if it lasts 24-48 hours. LOA told me they would eventually come back and apply some lower-grade TPO over the seams when they had leftover material from other projects. I don't know when they will do it but for now, I'll wait for them to do that since it's not the rainy season yet. I hope it will address the ponding issue. I also plan to monitor the roof during the rainy season in May and June to see if the water persists for more than four days.
