This house is 2 1/2 years old since I bought it. It's a 16 x 76 mobile home in El Paso Texas where it never rains until this summer; it's been raining for three months. Last week I had water running down through my heating unit, which I have heard turn on and off mysteriously a few times recently (I thought I was imagining the sound but I turned it off at the breaker board now). I went up and found a small place where the wind had blown off a piece of the shingle but I don't think that's in a spot where the leak could be coming from. I'm thinking the water either blew in through the vent or, I found a place where it appears they didn't finish running the shingles all the way to the end. This is pictured by where I am lifting it up with my lighter. Of course I have no idea what I'm talking about. I need help with understanding this because I am dealing with the manufacturer now, asking them to honor their "quality materials and workmanship." In two and a half years it hasn't rained but maybe 20 times until this summer, so of course I would not have noticed a roof that was not finished properly. I have more pictures if needed. Anything you can tell me about this situation, people, please....Viktoria It's kind of hard to tell in this pic but I am in the area where the roof is leaking, spot on. I can lift up here but nowhere else on the roof do the shingles end like it does right here. Now, looking down from the top of the roof, I can fit a lighter under the place where the shingles stop. Another set of shingles are there, continuing down the end of my house, but this just doesn't seem right: This pic is taken from where my lighter is, showing the vent for my heater, where the water was coming in last night, a lot of water. Could it be the water just blew into this vent??? And I don't have a roof problem at all? I mean, it rained so hard it filled half a big rolling garbage can I have outside that has no lid. This is just a blown off piece of shingle. Please tell me this isn't causing a flood of water into my house, because this isn't in the area, it's below the heater. The wind here is wicked. It could cause a problem though?
