How to fix patio roof leak
rosy

I got on the patio roof and here's what I saw. There is what looks like white tape over the seams between the panels that make up the patio roof. One seam's tape is cracked more than a foot long and another about six inches long. When there is heavy rain, water leaks through the cracked white tape. How do I fix this ? I couldn't find a you tube tutorial. Do I re-tape? What tape do I buy? Where? How do I apply it? Thanks!--Anyone done this before? I called the one who installed the roof for the previous owner and he said I should replace the seam tape on all 6 seams--he will charge $245 with a 1yr warranty. What do you think? thanks!

A pic should help.

Load your pic to a host like photobucket, then pass your code here.

You can also have the roof inspected by pro roofers. It sounds to me like it needs some work, not just a new tape.

Thanks for the tip on having a pro roofer look at it. I was hoping I could do it myself. The patio roof is unlike the home roof. It is made of several metal or plastic-like panels set one beside the other with space between each that is covered by water-proof white tape. Two spaces are exposed and need to be re-taped because that's the direction of the leak. Sorry but I won't be able to send a pic. I appreciate your response.

I don't know what you've got up there but every panel-type roof I've seen was designed to overlap at the edges for leak protection with no other sealing needed. How long did the old tape last? If the panels will last long enough then it might be worth letting that guy have at it again.

I do have to wonder about it all because a properly installed roof should not leak unless it is damaged or is at the end of it's life. So if this guy installed it it may not have been done correctly from the start. Just saying, I could well be wrong here.

Thanks for your Q&As. The patio roof (above a screened enclosure) was built in 2009. The tape is the original tape from 2009-- 6 yrs ago. I had a pro-roofer look at it & he said that for $1500 he will cover the patio roof so it will never leak again. I forgot to mention that the patio roof is made up of composite panels.

I don't know the size of this structure, so there is no way to tell you if this bid is reasonable.

Get the estimate in writing, have everything proposed down in the estimate, then call another roofer and see what kind of estimate he can offer you. Remember, you must compare apples to apples.

When you choose a contractor, ask to see a license before you sign. Don't trust your roof to a handyman w/o a license. The contractor's info should be printed on the estimate.

I have corrugated "milk glass" white plastic panels over my pergola. The manufacturer wants a bead of clear silicon but down where the panels lap over. Also, even though the screws which hold the panels down have a rubber washer on them, I put a bit of silicon caulk over the head of the screws too. I initially did not follow the manufacturer's directions and sure enough, I had some minor leaks. I backed of the overlapped panels, added the silicon, and now there are no leaks.

Thanks for your response. The patio roof is 10' by 22'. I bought 4" peel & seal white tape 250 to seal the cracking tape at two of the panel seams/joints. With a putty knife, I removed a small area of the existing 3" tape. The grey glue beneath the white area of the tape remains. It does not come off. I'm thinking of cleaning the taped area with 50/50 vinegar&water, then taping over it. Perhaps we need to exchange the 4" tape for 6" tape to do a better job. Any thoughts on this? Thanks.

Thanks for your response. My patio panels are composite and kind of look like what you describe above. They are "tongue and grove" type panels with 3" tape between the panels to seal the seams/joints on the roof area. I am wondering whether to put caulk between the panels (the seam/joint areas) where the tape is cracked, before I re-tape with 4" or 6" white tape. Any thoughts? Thanks.

I agree with that, I had a bad experience with an unlicensed builder, they claimed they had license but actually they didn't, I couldn't track them down coz they changed their number. So don't look for cheap labour coz you might encounter some dodgy business one day.
