It's raining again and my roof has another leak. Why don't they make self-sealing roofs. They make self-sealing fuel tanks for race cars and aircraft. Tires can seal automatically using pic-related. So why not have a layer of slime under the shingles or whatever is the top layer. I'm not a conspiracy nut but I think they might be holding back a revolutionary idea so we have to replace our roofs periodically.

Use a tarp, like all the human trash who doesn't bother to repair anything

If it's a metal roof, you can get Through the Roof by the gallon. A single tube is about $12. Use rubber gloves to apply it, just because it's sticky, and with your hands you can accurately go over the head of every screw that has a failed neoprene washer.

Typical homeowner nigger repair
Pull the nail or screw and replace with new low life

well that would probably fine for a roof getting pierced with .50 cal machine gun fire but since roofs leak reasons often unrelated to actual punctures it would not help.

If you want to waste it.

No. Unless your roofing screw is actually loose, and so you need to put in a larger one.

If it was a 100-yr old roof that was nailed-on, with lead caps over the nails, and the nails are pulling out, then ok: I will replace said nails with proper roofing screws.

Ice and water shield has a self-sealing component, but no asphalt or other polymer material is magically going to repolymerize over a hole. The closest thing we have in the roofing world to what you're describing is EPDM, and that's only because you slap some primer and uncured flashing over a hole and the primer polymerizes it to the existing membrane.

You could also theoretically have a layer of uncured butyl rubber or butyl rubber caulking material like water cut-off mastic encapsulated between the layers of laminate on the head lap.

Slime only works because you have compressed air in the tire and it will only work for a puncture in the tread. So if gravity worked backwards and you had a layer of Slime pusing up against the bottom of your roof, it could possibly seal a crack.

Everything is consumable and built to a cost. I’m sure you could make a 100 year roof, but it might cost 20x what a regular roof does.

I'm planning on building a house with a flat roof, and for maximum longevity I'm going with 90mil membrane, 1 foot seam overlaps, 24" wide flashing covering all seams, double details on all curbs and corners, and FM 30 year fastening details in the field and at the perimeter. If Carlisle made non-fleeeback 115mil, I would use that. Should be a legit 50 year roof. The only 100 year roofs are slate or clay tile with soldered copper flashings.

Copper roof pretty much does that; not quite 20x, more like 5x to 10x decent shingles.

Standing seam copper is retarded expensive. 10x is probably the bottom of the spectrum as far as cost. Underlayment has to be non-organic because it will rot over time, but soemthing Titanium UDL 50 will last forever.
