Roofing repair fail. Why do roofers do this?

[@jgg204]

lol did those guys patch a silicone coated roof with bitumen roofing cement? lol wtf

[@Yo-broski]

If you did that where i work at ,you would be fired faster than you can get to another leak call or scope job

[@AastroRoofing]

I'm sure they thought it was a good fix.

[@noanyobiseniss7462]

The only thing that sticks to SILICONE is SILICONE !!!

[@jamesford6846]

Nope. Asphalt will stick to silicone.

[@KILLERGUNNZ]

No, silicone sticks to asphalt. Asphalt will NOT stick to silicone. If you don’t know that, you aren’t a roofer or ever dealt with these type of work.

[@jgg204]

nothing sticks to silicone. and you have a 50 50 shot of silicone primer even holding up long term like this when doing a silicone patch on top. this is why we avoid silicone all together. too difficult to work with. if not done 100% correctly from the beginning, you are screwed. it's much easier to either go with commercial white TPO. or torch down modified bitumen, then roll an emulsion coating on top of that, and then rubberized silver coat on top of that. and then you will only have to coat it every 7-8 yrs after that and will never have to worry about seams separating

Roofing for 44 years. Forgot more than you will ever know. Asphalt will stick to silicone. Done it several times.

[@olejaerson1852]

No it will not, silicone sticks to asphalt not the other way. If we do this in Norway we lose oure license and everything.

[@AastroRoofing]

It only sticks until it cures, once it is hard, it peels right off. You are doing poor work if this is what you are doing. I have been roofing for close to 40 years and I just showed you what asphalt does over silicone. I see this all the time, guys like you keep me in business. Keep up the good work!
