This is a common mistake, which will lead to premature roof wear. What the installer should have done, was to install an A to B transition elbow, and continued down the roof with a section of down spout. Then used an A elbow to have the water dump directly into the lower gutter. It should end up similar to this Allowing the high volume of water to flow ...

Absolutely not safe. Those trusses were engineered with a heavy (critical) dependency on the bottom chords, which are in tension. Removal has left them extremely vulnerable to collapse due to spreading, especially under snow loads, but also under just the load of the roof itself. The roof system is basically a hinge now. To get a good mental image, ...

I would build a decorative arbor over the path. Its purpose would be to camouflage a basic gutter and downspout arrangement that dumps into the pond. Simple as can be. Image source

That is a balloon bird repellent device. It is designed to mimic the appearance of an owl to scare away smaller birds and prevent them from building nests in the eaves, or to prevent them from flying into windows. See https://www.amazon.com/Balloon-Bird-Repellent-Effective-Solution/dp/B01DAFTNEU

With no bracing above, you might want to check the out side walls - they are probably already spreading. Once they start moving the stabilization and repair can cost many thousands if the roof stays in place, tens of thousands if it comes down. There are ways to mitigate the damage done, but it needs to be done now before the walls spread, the rafters ...

Is it supposed to be like that? There needs to be air circulation in unheated space to prevent condensation causing rot. It's freezing up there That is good. It means your loft insulation is working. I'm more concerned about animals entering the house. I found fixing wire-mesh externally to any small gaps at the top of the walls keeps unwelcome ...

It's called a "Widow's Walk". The name stems from the fact that it was a prominent feature in homes near the sea, where wives of seafarers would (presumably) go to stare out at the ocean, hoping to see their husbands returning, but often finding out that they were widows.

Most likely an abandoned fireplace chimney, if evidence supports the theory that the bathroom under that area has been added recently. Otherwise they may have re routed a bathroom exhaust fan into it. Take the cage off and look down it with a flashlight.

Assuming a shingle roof. When to replace: It is leaking and can't be easily repaired. It looks bad. You don't like the looks, or the city is threatening to fine you for code violations. You want a better roof. Better hurricane resistance in my case. An unbiased expert says it should be replaced. The climate affects the expected life--heat is hard on ...

You could call it an "inverted syphon"... I'm searching for a word here, but it's not coming to me. Build a leak-tight pipe that starts at the house above the top of the pond wall. The pipe goes down, underground, laterally to the pond, up the exterior of the pond wall, then over the wall and dumps into the pond. This pipe will be pressurized so ...

Neither. It's labeling paint. It was either sprayed onto the entire lumber unit or this truss set for identification. source

Never, ever, feed them after midnight! Like gremlins, rubber roofs are very special and cool... But they have rules. You can get a rubber roof wet. You can expose it to direct sun. But you can't put tar on it! Ever. Not even a little. That product has a lot of fancy-dancy language designed to convince you to buy it. But it's tar-based, like any such ...

There are really two reasons to rake a roof (snow weight and ice dams), and there are two reasons not to rake (effort and roofing damage). Raking to reduce snow weight If you're concerned that the weight of accumulated snow will exceed load design limits, by all means pull some snow off. You don't want a collapse. This is a rare situation in northern ...

No. Layers of shingles on top of each other shorten the life of the roof due to the newest layer sitting on an uneven lower surfaces. The best life will come from removing all the old layers down to roof boards or sheathing and then laying down the new roof on a well repaired flat surface. Multiple layers of shingles happen because folks want to avoid ...

The triangle is an extremely stable form of architecture precisely because it has three sides. You remove one side, and you have one of the least stable forms of architecture on account that two members connected at a point can be affected by torque, which is by definition a force multiplier. If you want to play around with it to get a sense, try gluing two ...

I guess you mean a galvanized or otherwise coated steel. Life depends on weather, specifically rain. In a desert it will last forever. If the current coating is repaired at any damage spots, it will last almost forever. "Repair" could be anything from dabbing on roofing tar to sandblasting and coating with a zinc-rich epoxy (typically used to protect ...

Sounds like you need a chimney cap These come in a variety of sizes and shapes. They keep out most rain and snow and, most importantly, animals. You should attach any cap with stainless screws and lead anchors. Sealant is not a big issue, since there is no need for air or water tight joints. While sealant might hold in most conditions, strong winds could ...

Yes The granules (they're typically ceramic) act as UV protection and fire retardant. It's normal to lose these over time, but the shingle in your bottom picture looks to be missing as much as half its granules. Additionally, the larger the hail stone, the more likely it damaged the shingles themselves (1" hail stones are serious). Most homeowners ...

Your plan is exactly right, except that you don't need such heavy-duty hardware to do the jacking/winching. Even a pair of motorcycle ratchet straps or a come-along is going to do the job, especially if you jack up the ridge board. I think it'll all move easier than you anticipate. Just make sure you have solid connections to the walls so you don't have any ...

I would suggest actively saving/setting aside money specifically to replace it, perhaps in 4 years if it appears to be in good shape now. 25 years is a pretty typical rated life, and your costs for replacement go up a great deal if small leaks you don't notice inside the house cause the roof decking to rot before you replace the roof.

No contractor needed. Cut a piece of 1/2" plywood 3-1/2" X 12", drill 10 screw holes in it, slather it with glue and screw it on there. Might be overkill, but should do the job.

This is caused by: poor roof design poor gutter installation Since it's not cheap to fix the roof, the solution is to fix the gutters. You simply need larger and/or repositioned gutters. The catch is if you also have heavy snow loads. In that case, you also need strong, well-installed gutters. :) In this case, since it's really only one spot, I'd probably ...

As a R.R.C. and roofer for over 25 years, this doesn't surprise me. Anyone with a pickup truck and a ladder calls himself a roofer. This is wrong, if they eliminated vents they should have replaced the sheathing. An opening up to 4"x4" can be covered with metal, but anything bigger requires re-sheathing to eliminate a fall hazard. Also the nail pattern ...

If you need to fix this so you can sleep better at night, any carpenter would be able to sister this truss for a repair. In my humble opinion though, no repair is needed. If you look around up there, there' a good chance you'll see notches cut all the way through for cables, conduit, pipes, etc.

The best way is to go around the roof, not through it. As soon as you have a hole, you are providing a path for water. You can seal it, but it's always going to be a weak spot. Additionally, if you ever need to redo the roof, it will be a pain to deal with the wires that are now in the way. Better to come out of wall, then go up to the roof. You still ...

I would give your business to one of the "is good and stays dry" roofers who are not blatantly trying to fleece you. Now, the other two may be working from the assumption that if you bothered to call a roofer, you have leaks. But they strike me a lying scammers if they are selling you new plywood with no idea if the roof deck is rotten or solid. Plywood ...

As pictured - very bad idea. It may work IF the roof is re-engineered to carry a lot more of the stress across the top and bottom of the cutout. That means a much beefier horizontal beam on all four sides of his hole AND a rework of the roof by re-trussing the entire structure. Some examples: This one is a Scissor Truss, and also wears the more ...

Clearly this has been a problem for a while and also the standing water and patch job on the flat section of the roof is to blame. There is no real shortcut here, as you can see, so the solution is to remove the roofing, repair the water damage, and then have it re-roofed properly. There are ways to apply a flat roof so that it will not leak but slathering ...

You should not be touching your shingles when raking. If you have 5" on roof you don't need to touch it. If you have 24" on roof you don't need to rake the last two inches. Also rake in the early morning so sunlight helps distribute water/ice better. There isn't general advice to give because it is dependent on the amount of snow on your roof,...

You have either, too flat of a pitch in your roof or installed your roof tiles incorrectly. Just accept it and move on. It's going to have to be redone. You would be wisest to tear it all out, then get someone who knows how to do it correctly in to do it. If you half-ass it now, it will just come back later, usually after causing structural damage for years....
