Hi, it's Steve, I'm Roofer911.

I'm on your roof and the leak that you have inside the sunroom is right about in this area here. It's very possible the leak could be coming from up above and I noticed the way they did the valley, here, they put nails too close to the valley centerline and that's something you never do.

Even though there's a problem here, that's not going to cause the water to travel this way but, in this section here, this could cause water to settle inside the sunroom back. It can go back even as far as six feet. What I'd recommend is to change this valley, here, install ice and water shield which is a rubber membrane. It will be fully adhered to the metal flashing and then we'll re-shingle this area.
    
Also, directly above, you have a ridge vent. If the vent is not sealed underneath, that can also attribute to the leak because underneath that ridge vent, the wood sheeting is cut approximately one and a half inches on each side of the ridge and that's so the hot air inside the attic can go straight up and then escape through the sides of the vent.

I noticed the way they installed the vent was wrong. They cemented the seams and there's really not that much of an overlap and the same thing over here. I could see that there must have been a leak here one time because they put silicone and cement on top of this.

What we'll do is ... I would highly recommend to change the ridge vent. You can see, I'm directly above the area where you have the leaks. All the shingles in this area here are good, so nothing here is attributing to that leak below, except for this vent.
    
I noticed with these two vent pipes, one of them is installed incorrectly and I'll show why. They cemented it, but here, the water can channel its way inside here and go underneath the flashing of the vent pipe and then you'll have a leak.

Also, the collar here needs to be sealed because it's a loose fit. Now you definitely have a leak here. You can see the pipe flange is completely deteriorated so the water's seeping inside the attic and the reason why you don't know you have a leak, for now, is only because the insulation on the floor in the attic is absorbing the water. Once the insulation becomes saturated, then that's when you're going to notice water damage.
    
Let me show you something here. We can walk on the sunroom but only on the rafters and also down the middle of the ridge. If we step in the middle of the rafters, then we're coming through.

What I really recommend is to clean off a lot of this old cork and then we're going to re-seal it with polyurethane. It's a much, much better bond and you can see over here, right in this area here, you can see that the sealant is deteriorated and also back over there as well.
    
All right, my name is Steve. I'll have a proposal emailed to you very shortly. Thank you.

Finding The Source Of A Roof Leak In Annandale, VA

Finding The Source Of A Roof Leak In Annandale, VA appeared first on www.Roofer911.com

 

Hi, this is Steve from Roofer 911.

I'm on a home roof in Annandale, Virginia that has a roof leak because of improper installation of the roofing materials. Where the leak is settling is right down in this area here where the flat roof is. I noticed a few different things that's causing this leak.

The contractor was here three different times. He originally had shingles, and then he put the flat roofing material, but also you can see that he started to panic. Instead of changing the valley, he applied cement right along the entire length of the valley. That's only masking the problem. What we need to do is remove all the roofing material at both sides of the valley. We'll install ice and water shield underneath, and then we'll re-shingle that area.
    
Everything above the area where we have the leak, we need to focus on it. If we don't, we're going to be back.
Also there's another valley here that leads down to the flat. I notice there's nails fastened too close to the valley center line. Another problem is, which the contractor didn't even think about looking at, is the flashing around the skylight. Here, I'll show you an example.

Right there, the water can get in through the keys, and also the water can seep in through the side, go underneath the shingle, and the water will seep right through the side of the nail. Eventually the water is going to settle directly below, but what's happening now is the water is seeping through the side of the nail and it's traveling underneath the roof. It's hitting the valley and then it's settling down at the lowest point down at the bottom of the flat roof.
    
What we need to do is remove all the roofing material completely around the skylight. Any flashing that's damaged is going to be repaired or replaced with new. Then we'll install ice and water shield completely around the skylight and then re-shingle the area.

Also there's another skylight that's about twenty feet away from where the water settled inside the home. They have exactly the same problem. Here you can see there's a nail exposed here, so again the water will just get right through the key and seep through the side of the nail. Another thing is if these shingles are fastened too close, say there's a nail here, when there's a heavy downpour or melting snow, the water can get up underneath here and then leak inside the home.

We're going to do the same procedures as below. We'll install the ice and water shield here and nail very high.
    
Also this ridge vent is in direct alignment where you have the leak down below, so we need to remove a section of this ridge vent, install a ice and water shield underneath, not to close off the breather, and then re-install the ridge vent.

This other skylight is not leaking, but it's going to because it's the same thing. They put nails into the flashing. Okay, let me see. Okay, right here. This nail should not be exposed. There should be no nails exposed at the flashing. Instead this flashing should be fastened underneath this one here so this piece here overlaps the nail. Then once it's done that way, then there's no leaks.

Overall the skylights are great. It's just poor installation of the shingles around. Let me check this vent pipe because this vent pipe is also in direct alignment where you have the leak. Let's see what we got here. Oh, it's all cemented down. Yeah, it's all cemented.
    
As a precautionary measure we're going to take up the shingles around the vent pipe flange, install ice and water shield around it, and re-shingle it.

With this leak I'm focusing on everything, so this way it does not come back again.

Ridge Vent and Vent Pipe Roof Repair in Reston VA

Hi, this is Steve from Roofer 911.

I'm on a roof in Reston, Virginia, and they have a leak that's coming in at the vent pipe and also the ridge vent. I noticed there's nails in the flashing completely around the pipe flange, so we're going to remove all the roof material completely around the pipe, seal the flash with an ice and water shield, and then re-shigle the area.

Now visually when you look at the ridge vent, everything looks perfect. The nails are are sealed. It's fastened correctly. The problem is it was never waterproofed underneath. What we need to do is remove the ridge vent.

Any shingles that are damaged, they're going to be removed or replaced with new, but very important, we're going to seal underneath the ridge vent with polyurethane. Then the ridge vent is going to be pressed right into the sealant. Then when we fasten the ridge vent into place we need to make sure that we nail it into the rafters like every twenty-four inches. Once the ridge vent is fastened, then we're going to seal the nails.

Now another thing is, with the polyurethane underneath the ridge vent, it will block any water from getting underneath, from a heavy downpour, wind driven rain, or melting snow.

Once we're done with the roof repairs here in Reston, they will not have any more roof leaks.

My name again, is Steve. I'm Roofer 911, and I can be reached at 703-475-2446. Thank you.

Chantilly VA Roof Inspection and Roof Repair

Chantilly VA Roof Inspection and Roof Repair appeared first on www.Roofer911.com

 

Hi, this is Steve from Roofer 911.

I'm on a roof in Chantilly, Virginia and the homeowner wanted me to do a roof inspection because he was afraid he may have some problems. Sure enough, he does.

Down at the bottom of the valley you can see there's two large holes. Okay, right there. Right down at the bottom, right over there. The reason why is when the contractors first install the vinyl siding they used pump jacks. Pump jacks are a long pole, usually made of aluminum, that are mounted on the ground and then they come up above roof level. Then the pole is braced into the roof.
    
Once the contractors are done with the vinyl siding, then it's time to take the pump jack poles off, and the brackets off. Then they pull the nails out that were holding the brace into place, but they never replaced the damaged shingles. This is a large hole that goes right through the plywood underneath and there is causing leakage inside the home, but the homeowner may not even know because the insulation inside the wall, or inside the attic is absorbing the water for now. What we need to do is replace these damaged shingles and then everything will be fine.
    
I wanted to show you a few other things. They have aluminum ridge vent. Before the ridge vent was installed they nailed the top course of shingles into place, but they placed the nails too low. You can see, like right here there's an exposed nail. When they were nailing the shingles, the nail guns are controlled by an air compressor. The air pressure to the guns was set too high, so the nails are over driven. With a heavy downpour the water's seeping right through the nails and then inside the house. You can see it's like this in many different areas right along the entire top ridge over here, too.
    
Another thing I noticed is they have solar energy fans and the flashing is all wide open. When there's a heavy downpour or a melting snow, the water can get underneath the flashing, then the water will seep right through the nails. Then the water will leak straight down into the attic but many times the water doesn't stop here. The water continues to travel down the roof underneath the shingles on top of the felt and it will settle at the valley.
    
The first thing the homeowner will do is if he notices a leak in the valley, he's going to call a contractor. The contractor's going to see the water damage inside the home and he's going to see that the valley is directly above. The first thing he's going to do is repair the valley which is expensive. He's not going to focus on repairing a problem up above. If the valley is taken care of and the attic fan is not, the leak will come right back again.

Also, this attic fan in the back is done exactly the same way. What we need to do is remove all the roof and completely around these two fans. We're going to seal the flashing and the wood deck underneath with ice and water shield and then we'll re-shingle it.
    
Back to this ridge vent. Being that they have all these nails exposed, what we're going to have to do is take off this entire length of ridge vent which is about forty feet. Once that's done, we're going to replace these shingles and nail high, then after the shingles are fastened, then we're going to seal the deck underneath the ridge vent heavy with polyurethane. Then the ridge vent is going to be pressed right into the sealant. Then when we fasten into place, we need to make sure that we hit the rafters underneath. Then we're going to reseal the fasteners. This homeowner, I can guarantee he has leaks but he just doesn't know it because like I said, the insulation below is absorbing the water.
    
Now another thing, when I was coming up the roof I noticed the lower roof had many nails that were exposed. Let's see if I can see it. Yeah. Okay. You can see right here there's a lot of nails that are going right through the face of the shingle. The reason why is they had some shingles that were missing and they replaced some of the shingles, but they did a very poor job. To make sure that the shingles don't blow off, they drove nails right through the face of the shingles, and that's going to end up causing a leak. Also, they have two shingles here that are buckled and they're probably not even fastened underneath, or the plywood underneath could be rotten. We need to repair this area.

Hi, this is Steve from Roofer 911.

I'm on a roof in Mclean, Virginia, that has multiple roof leaks. One of the leaks I noticed inside the home, was right in the area of the valley, but then also along the wall, and it went all the way down to the gutter line. What we need to so is, we're going to have to remove all the roof material on both sides of the valley, and also, where the roof and the wall meet.

Let me show you something here. This roof is very, very tight. There's no way I can lift up any of these shingles at the seam, because they have ice and water shield, most likely, installed underneath all the shingles. Here, at the valley, it's very, very tight. I can hardly even lift it up, I can't even lift it an inch.

When that happens, it tells me one thing, when the contractors did the roofing, at the valley, they had fashioned the shingles too close to the valley's center line, so when it rains really heavy, the water can get underneath that seam. Like I said, that nail is only a few inches away from the center and the water gets underneath the seam, then the water seeps through the side of the nail and into the house.

We need to remove all the roof material completely around the valley, install new ice and water shield, reshingle it, but this time we're going to fasten about nine inches away from the center of the valley. Also, where the roof and the wall meet, we need to take up all the shingles, here, because when they fastened the shingles into place, they nailed the shingles too close to the wall, and by doing that, they damaged the protective step flashing underneath.

Now, another thing, very important, even after the roof is installed, there's a very good chance that a leak will come back. I'll show you why, the gutter, here, the downspout is on the left side. They have an end-cap on the right side, so no water's draining over there, and the gutter's low, here, in the middle. When it rains really heavy, not only does the water overflow over the front, but also, the water goes over the back. Then the water settles inside the exterior wall cavity between the outside siding and the drywall. Once the insulation inside the wall becomes completely saturated, then the water will let loose, and then you see the water damage inside the home.

Now, also, they have a leak that's in-between these two skylights, and there's a 750 vent that's directly above. This vent is very likely attributing to the leak below, but I cannot remove the shingles around here to check the overall fastening procedures because, like I said, it's very tight just like the rest of the roof, because of the ice and water shield.

The best thing to do is remove all the roofing material, install new ice and water shield, and then reshingle it. Another thing, very important, like I said, they have a leak in-between these two skylights. Now, here, when you look up the roof, here for example, there's a seam right here where this shingle joins up against this one.

Now, when the contractors originally did the roof, they used roofing nail guns. Now, with a nail gun the contractor can fasten anywhere from five to eight nails a second. If he doesn't pay attention to where he's placing each and every nail, especially when they're in a rush, some of the nails are going to be exposed at this seam. Even though the shingles are very tightly adhered to the roof, the water can still seep through the seam, then the water will leak right through the side of the nail, and the water will just travel down the roof, on top of the felt, and wherever the water finds an opening, like a tear in the felt, that's where it will settle. With this leak, we need to focus on everything.

Also, the homeowner said that there was a leak next to the skylight. What we'll do is remove all the roof material, completely around the skylight. Then we're going to install ice and water shield, then reshingle it.

Here, you can see somebody put caulking where the roof and the side of the skylight meet. Whenever I see something like that it tells me one thing, there was a leak here before and somebody tried to resolve the problem by caulking the area. Caulking is just masking the problem, you have to take things apart to get to the source.

Now, another thing is, where the dome meets up against the metal, many times there's hairline fractures, right at the metal and the water can seep right underneath, and then it will leak at the skylight, and then settle down near the gutter.

What we'll do is clean up all the dirt and dust completely around the skylight, and then we're going to seal it with polyurethane, and that's it. With this leak, we have to target everything as a whole, because if I don't, I will most certainly be back in the future, that's something I do not want.

Again, my name is Steve from Roofer 911, and we specialize in roof repair in all areas of Mclean, Virginia, and all areas of Northern Virginia. I can be reached at 703-475-2446. Thank you, and have a wonderful day.

Hi, This is Steve again, Roofer 911. This is a continuation from the last video of the home in Mclean, Virginia.

The homeowner has another leak around this skylight. One thing I noticed, right off the bat, is after the skylight leaked the first time, the contractor came back a second time, and he installed what they call a water diverter on the back side of the skylight. They're really a complete waste. The reason why it leaked to begin with, is because of improper installation. Most likely, they have nails fashioned too close to the side of the skylight, say here. When it rains heavy, the water comes down the roof, and then it backs up underneath the roofing shingles, and the water seeps right through the sides of the nail and into the home.

Now, the water diverter is nailed up here, so the same thing can happen here. The water can hit the diverter, especially during a melting snow, and the water will go underneath the shingles, and seep through the side of the nail. Also, what about the space between the water diverter and the skylight? When there's a very heavy rain, the water's going to get inside here, and it's going to find the same opening as before.

What we need to do is remove this water diverter, and then remove all the roofing material completely around the skylight. Then we're going to install our ice and water shield completely around, and then reshingle the area. Now, also, we're going to seal where the dome and the metal frame meet, with polyurethane, because, as with the other skylights, this eventually can lead to a leak because of hairline fractures.

Also, this skylight is too big for the frame, and you can see on the inside here, it's about six inches too big. It's the wrong size, but that's okay, just as long as everything is water-proofed correctly on the outside, they won't have any problems. The leak to the skylight also, is not coming from up above. It's strictly because of the skylight.

Now, looking at the roof further, I see you have no ridge line going across the top, so you can develop condensation buildup in the wintertime. The attic fan is very good for the summer, it releases all the warm, moist air, but in the wintertime it will not work. The thermostat is set to a hundred degrees, so the only time the attic fan is going to work, is when the temperature gets hot in the attic.

What I would highly recommend, is to remove these cap shingles, cut through the wood sheathing, approximately one and a half inches on each side. Then we're going to install our ridge vent, so this way all the warm, moist air in the attic, it rises to the highest point and it will go out through the ridge vent.

Condensation is very, very common, especially in the wintertime and people develop mold from that. It can turn into a serious problem. Now, this roof here, the lower roof, there's no ventilation here at all. There's one little 750 vent, but that's only ventilating the area in-between the rafters and it's not even up high enough. Again, I would install a ridge vent here, because this home is just asking for mold.

Again, this is Steve, Roofer 911. Thank you.

Roof Valley Leak in Arlington VA

Roof Valley Leak in Arlington VA appeared first on www.Roofer911.com

 

Hi, this is Steve from Roofer 911.

I'm on a roof in Arlington, VA and they have a leak there down at the bottom of the valley here. What happened was, the homeowner originally called a contractor and he redid the entire valley which is good. This valley is okay but this valley over here, there's nails fastened too close to the center. It only leaks mainly when there's a heavy downpour or a melting snow.

What we'll do here is the same thing that the other contractors did over here. We'll remove the flashing. We're going to remove the shingles on both sides of the valley. Then we'll install ice and water shield right down then middle. Then we'll re-shingle it and we'll install a single cut close type valley like they have here.
    
Another thing is, after the valley is done, there's a very good chance the leak is going to come back. The reason why is the shingles that are on this home is certain pead horizon and they've been discontinued now for about 7 years because of premature aging. If you look at the roof very carefully, you can see all the stress fractures and it's like this all over the roof. The water can very easily get through the fractures and travel underneath the roof and then just settle here at the lowest point. I highly recommend to redo this whole section here and redo this but the roof is old. It's 23 years old so the rest of the roof has problems as well.
    
Honestly, I would highly recommend to remove and replace this whole roof because I guarantee you have other leaks that you just don't even know about yet. Also, where the roof and the wall meet here, there's nails fastened too close to the wall and by doing that, the contract is nailed into the step flashing underneath. That will also attribute to a leak. That will be here at the bottom of the valley but eventually that water will settle at the chimney.
    
After looking at this roof further, they have an attic fan here too and the attic fan was installed wrong. You can see the metal flashing is overlapping the shingles. The shingles should have been overlapping the flashing. The only place where the metal should be exposed is down at the bottom where the flashing overlaps the shingles. Again, with this roof, I would highly recommend to remove and replace it but I'll give you two different options.

Hi, this is Steve from Roofer 911.

I'm at a home in Leesburg, Virginia, that has a couple different leaks.  One of them is these two windows here that have hairline fractures at the corners of the sills, so we need to seal the inside corners with polyurethane and that will prevent any further leakage during a wind-driven rain.

The counter flashing up against the wall here is sealed fine. That's no problem, but once we seal the hairline fractures, then the leak is gone. Now, also there's another leak right here in the corner where this roof meets up against a wall and the water is settling at the lowest point, so there's a few different things that's causing the leak.

The first thing we need to do is remove all of the roofing material where the shingles meet up against the wall on the lower roof. Any flashing that's damaged can be either repaired or replaced with new and then we're going to re-shingle that area. Now once that's done, it's going to still leak and the reason why is because of the upper roof here where this roof meets this roof, there's a valley right down the middle.

When the contractors did the roofing, they fastened the shingles too close to the center of the valley and by doing that, when there's a heavy downpour or melting snow, the water is getting underneath that single-cut seam and it's finding an opening through a side of it now and now the water is traveling down the roof in between the shingles and the felt and it's settling down inside the exterior wall between the vinyl siding or between the bricks and the drywall inside and then the water is settling on the lower part of the roof. We need to take up the shingles on both sides of the valley, install ice and water shield and then re-shingle it.

Now once the valley is repaired, the leak is still going to re-occur again, but only this time during a wind-driven rain or a melting snow. The reason why is you have two ridge vents, one here and one over here. If it's not sealed underneath or if the open breathing space is cut too wide, it will leak. We need to take off the ridge vents and then we're going to seal underneath it with polyurethane and then we'll re-install the ridge vent and seal all the fasteners. Once we're done, we've targeted this leak from every possible angle so the leak will not come back.

Now once that's done, it's going to still leak and the reason why is because of the upper roof here where this roof meets this roof, there's a valley right down the middle.

When the contractors did the roofing, they fastened the shingles too close to the center of the valley and by doing that, when there's a heavy downpour or melting snow, the water is getting underneath that single-cut seam and it's finding an opening through a side of it now and now the water is traveling down the roof in between the shingles and the felt and it's settling down inside the exterior wall between the vinyl siding or between the bricks and the drywall inside and then the water is settling on the lower part of the roof. We need to take up the shingles on both sides of the valley, install ice and water shield and then re-shingle it.

Now once the valley is repaired, the leak is still going to re-occur again, but only this time during a wind-driven rain or a melting snow. The reason why is you have two ridge vents, one here and one over here. If it's not sealed underneath or if the open breathing space is cut too wide, it will leak. We need to take off the ridge vents and then we're going to seal underneath it with polyurethane and then we'll re-install the ridge vent and seal all the fasteners. Once we're done, we've targeted this leak from every possible angle so the leak will not come back.
