How to fix a leak in a valley of shingle roof with Utility Knife only - Warning! do not use Tar

This is a common leak in valleys of shingle roofs. Just a utility knife and the leak is fixed. Most people would use tar and caulking to make this roof repair, but that creates more problems.

Wish my wife was a fraction of that impressed with my building skills😂

[@jorgelmartinez3453]

Great..!! 👏👏👏👏

[@MrMoss786]

Nicely diagnosed and resolved. Well done.

[@FlatRoofDoctor]

Thanks

[@Mhvlogg]

It would be so intressting if you do a video, when you show us your day to day tools, like what tools do a roofer needs when your working with torchdown and so on. Hope you understand my english and asking :) You are great 💪

[@FlatRoofDoctor]

Great idea I carry very little tools around. But I will try to make a video on that. Thanks

[@johnnyhurst9518]

The bad thing is you drove your knife instead of pulled your knife, thus cutting the shingle underneath. Hook blades are to pull not press. Dub the corners on the tops as well helps.

[@wolfmann4666]

Very clever!

[@FlatRoofDoctor]

it works

[@nolancoward8787]

I put my roof on and I'm having the same problem but when you make your cut I'm on my second layer do you have to have somewhere to circumvent that water

[@redsresearch]

after you finished cutting did you put sealant under the overlaping shingles after you cut? who knows if there shingles went over far enough on the underside

[@DavidSanchez-ot3it]

Good stuff my dude, u a bad man ,, feel me ?

[@luisgranados9992]

So what if I have like an aluminum shingle running down the same pattern, does it also collects debris??.., because it leaked during some rain we had a couple of weeks ago... and the same leak we had 4 years ago ,i believe in the same spot,although I didn't see where exactly the leak was,I had some else repaired it for me...

This is happening in my house in Tucson AZ , I have a guy coming out to give me an estimate on Friday… I also hate shingles… hoping there’s a way to get rid of them and install rolled roffing on my gable roof with 2 valleys

[@FKS1994]

Loving that new look with the beard! I have a question for a flat and low slope EPDM roof. If there is a small tear, do you recommend a patch with a polyester fabric and silicone roof coating?

[@FlatRoofDoctor]

You use the Super Silicone Seal with the Polyester Fleece to make the repair. Your question was incorrect. You cant use Polyester fabric by itself.

[@FKS1994]

@@FlatRoofDoctor Okay, yes, that is what I meant. Is that a better option than just adding another layer of EPDM?

[@sevenhighclub2339]

Nooo you need epdm sealer glue for repairs and they also have patch kits. You guys have no clue

[@cintiagaristasolis1210]

Wooow! Amazing job

[@FlatRoofDoctor]

see you guys soon

[@kylekoverola8654]

Nice beard growing!!

[@FlatRoofDoctor]

Thanks! The wife insisted. Now I am stuck with it

[@happydays454]

I worked with my uncle he always put a tin valley

[@FlatRoofDoctor]

That is one way to do it. But, it is not always desirable to have a metal valley on a shingle roof because of the looks. With shingles covering the valley, it is less pronounced. The metal does give it a different look.

[@apexwinterswind8241]

Won’t debris just build up again in the new shorter edge?

[@panchotheaddict420]

no because the new edge is more up along the roof in instead of being down in the valley where water will naturally collect.

[@tclodfelter8789]

What keeps debris from collecting under the new shingle line?

[@jaketheheals]

By cutting a few inches away from the actual valley creates a trough for the water to flow thus never having debris build up

[@tclodfelter8789]

@@jaketheheals So I'm finding out! Thus the search...

Very nice. Where's the second party -- if it exists.

Or just do a woven valley or an open valley with flashing

yes those are all done, any style is good

Every man should be jealous of the wife you have ! I need me a roofing wife because his knows I love roofing 😂🙄

[@kylekoverola8654]

We use metal in Vancouver bc

[@FlatRoofDoctor]

Yes, metal is another way. but for aesthetics, some people prefer to weave the shingles or do what is was don in this video

[@PolyglassUSA]

Hello Flat Roof Doctor! We love your contents and we send you an email. Thanks!

I used to use Polyglass in the past. I saw your email. Call during the week. I will be traveling a lot this month

[@DeathlyCodYoloHD]

Poly glass is trash compared to suprema or iko

[@mikethompson7436]

I bet it leaks where the wall transfers to the valley you'll be back

[@thomashadwen6864]

Uhh you need a metal valley

[@FlatRoofDoctor]

not always, this method is also done by many

[@nathanhildebrandt2672]

After running the first course of shingles through the valley, I always take a water bottle, and pour it in the valley, and then snap a line just to the side of the waterflow, to make sure the water isn't fighting to get under the top course of shingles.

[@douglascunningham148]

Lol, its leaking because whoever did the roof before didnt dog ear the corners on the valley shingles
