Anyone have a solution?

Barrel roof. Sliding snow damage. Ripped off cover strip and damaged drip edge

I agree with others about a wider cover strip. Having only 2'' (or less) adhering to the base rubber isn't enough. If that minor damage is allowing water to get in behind the gutter, you better check to see if the epdm goes all the way to the gutter under the drip edge. If not, correct that as well.

Mike, I installed something like that on the tile roof I did about 3 years ago. With the special painting and such plus installation it came out to about $150.00 a foot. A lot more expensive than the glue on guards, but permanent.

Tom?

Glad I read the rest of the post, ....

Alpine's utilize a heavy extruded aluminum tube, 6 of them I believe, cut to length to match the height of the roof profile from deck to membrane. They are sunk into the system, then a good application of cut-off is applied to underside of a very heavy base plate, including the hole locations. Base plate is screwed to deck through the tubes. No stress is applied to the roof system. The base plate can be painted to match the roof system AND covered with a membrane patch.

They are expensive, labor intense, good, effective, and worth the money if snow retention is necessary.

Tom, are the Alpines adhered through the rubber roof? That was my concern. It looked like it was a fully adhered rubber surface, and I would hate to have a bunch more holes punched into it. IF the plastic sno- gems would adhere and hold, they would do so without penetrating the membrane.

Like you say, you can't over clean the surface. good job!

Scrub with abrasive pads with soap and water, rinse well.

Then apply the PS primer with an abrasive pad providing good agitation.

If this is an adhered system that's losing bond, instead of 9", maybe move up to 12" and install a row of batten 8" from the gutter edge.

Probably over kill, but you can't OVER clean old rubber.

If you used 12" rubber and seam adhesive, you'd have a lower profile than using PS products. On old rubber, I tend to prefer adhesive anyway. A good feathered bead of lap seal will leave you with a nice smooth surface and very little resistance applied to the sliding snow.

For real snow retention we use alpine snow guards. Not cheap, but very effective.

I am sure they will stick Tom, but what Lefty said about the strain on the EPDM is of concern too. Basically you are transferring the weight of the ice to the rubber if you adhere to the rubber. If you spread it out though it is transferred through the whole sheet. The wider cover strips are a good idea. They have them at ABC up here and I am sure down there. CLEAN IT WELL BEFORE YOU APPLY IT!!

I would not try to keep that weight up there. On a residence maybe. I would think you are going to put a lot of stress on the sheet.

They all make it. You can get 9" or 12". Leave the old stuff in place except where it is loose. Cut that out. Just clean it good and use the 9" and you have the 3" sticking to the sheet that you need.

This has been going of for a few yrs, Clover. Snow/ ice shelves are common. I've been telling the owner that he should consider a sno bar, or something...

The sno gems are good for rubber OS?

That's a good idea too Lefty. I was going to put 6" on instead of the 5 there now. Is that 9" just a product from certain manufacturers? I've never bought it.

9" cover strip

This only happens when we get a severe winter like this one. Perhaps the "sno gems" ice guards that attach with a epoxy caulk to the surface. You have to clean it first with an alcohol based cleaner and then stick them on. You have to use quite a few, and spread them up the roof above the area you are trying to protect, but they will hold the snow in place and let it melt. They are made of clear plastic so they are not "sticking out like a sore thumb" but they are visible.

At least they secured that gutter well.

I have a 1 year old TPO job with huge sheets of ice sliding off. I guess I'll be adhering ice clips to the surface?? I couldn't find any that weld on.

This is on the back of a guys clear story house. I never even considered that possibility. It's a 1.5/12 approximately. His heat pump & a/c are right below so I hauled ass down there to help setup protection w/ a step ladder and board.

Weird thing is, one minute before he called(4-5 nights ago) I had put a picture of his roof on my website!
