Wind Driven Roof Repair
Now you see it, now you don’t. Well there’s a mystery for you. We’ve had it happen to us and here’s what you need to know about it if it happens at your business, too.
How many times has that happened to you? You see something and you want others to see it too. So you call someone to come and look at it, but by the time they can come it’s gone… disappeared. No, not a UFO… water leaking into your business when it’s raining. But the mystery is, that it doesn’t leak every time it rains.
So it’s hard to get someone to look at with you when you don’t know when it’s going to happen again. We *recommend Fireman Roofing in Arlington to come take a look at it if you’re having the same problem.
So, what’s the deal Bill, what’s going on?
Well, probably it only leaks when the wind is blowing. And most likely the mystery is “wind driven rain.” Your roof may not leak every time it rains. Unless it leaks every time it rains, then it’s not just a problem like a missing shingle, hole in the roof, or a flashing issue. The problem is caused most likely by wind that is being blown horizontally.
Unless your roof is completely sealed from top to bottom there can always be a possibility that moister can be forced in by wind driven rain. That would include every, crack, cranny, vent, perforation, slot, slit… well, you get the picture. Most roofs are designed for the rain to just run off. But wind can be driven sideways blowing rain up into the inside of the vents on your roof allowing the water to enter the attic and running down to even stain the ceilings in the interior of your home.
The wind can also blow the rain up under the eaves of your roof. And if not properly sealed around the trim with caulk, they can leak as well. Most ventilation systems on your roof prevent rain from entering your attic. But even the best of ventilation systems can allow wind driven rain to enter if the rain is propelled at just the right angle.
Other areas where wind driven rain might enter is through turbines. Turbines have louvers that allow heat to be drawn out of the attic by the wind blowing across them but the same louvers can allow access into the attic by high velocity wind. There are also a number of vents that may well be the problem too. Soffit vents can allow water to be blown up inside the soffit by high winds that ordinarily would be no problem. The same is true with gable vents, ridge vents, and turtle type vents.
In short, you may only have leaks when the wind is driving the rain at a high velocity or driven horizontally. To be sure your problem can be addressed properly call your qualified roofing team to analyze your roof and give you their expert opinion. They have seen it before and can advise you what needs to happen in order to solve your mystery.
