Pros/Cons and Comparisons to competitors
BurghFan✓ Verified Purchase•July 29, 2023
Pros:
- Works great if it is being run with the slope of the deck (no need to worry about building your own slope).
- A "funnel" can easily be created at the end of the run to channel water into a gutter. This is done by cutting two small pieces (~8-9" for 10" joists), facing and sloping them towards each other into the gutter.
Cons:
- As other people have mentioned, it is very difficult to work with at first. I suggest using a small 12" piece and don't fully tack it down for practicing.
- Does not work well when the joists are parallel to the structure (house). There is no "natural" slope in this type of installation and requires you to create your own slope.
- Creating a funnel like suggested in the video is not easy and requires extra time.
Comparison to competitors:
- Cheaper than Rain Escapes but more difficult to work with.
- More expensive than EPDM rubber roofing but EPDM rubber requires more planning and at least one other person.
I personally used EPDM roofing for most of my installation (my joists are parallel to my house) and then used this product to complete it when I ran out of rubber. I also used this to create "funnels" into my gutter. I would have given this a 5 star rating if it was a little easier to work with.

Heavy weight material

Ensure that the deck is framed with a 1/8 to 1/4 inch fall per foot. Unlike other brands that you install with a slope this material relies on the deck framing to drain properly.
Product is not easy to work with in Direct sunlight

Installing it during the day with the sun hitting the product , it was expanding as I was installing it and it made it very difficult to install. But overall it works great .
Great product and price

After installation for 3 months no issues works as expected. Keeps the space under the deck dry and clean. I do plan on purchasing more of this product in the future
Works as descried

Easy to use product for one person if you pre-install depth guides. I installed a a guide every 2 ft, each guide 1/2 inch lower than the last giving a 1/4" dropper foot along the length of the joists. Wet winter went by and the underdeck stayed dry.
