Bleach [amzn.to/3bffNEY]
Steps:
1. Start by securing the harness system to the roof, following the manufacturer’s instructions to ensure they’re installed properly.
2. Using the push broom, lightly sweep the roof to get off as much of the loose moss as possible.
3. Install a zinc strip near the ridge of the roof. When it rains, water will pick up the particulates in the zinc and deposit them along the roof, preventing more moss from growing.
a. Roll out the zinc strip underneath a course of shingles, allowing roughly half of it to be exposed and the other half underneath the shingles.
b. Nail roofing nails about halfway through the zinc strip, just to get it held in place.
c. Apply a bead of roofing cement around each nail before nailing them all the way through. This will help seal up the hole made by driving the nail.
d. Once the nail is all the way through, add another bead of roofing cement on top of the nail.
e. Repeat this process for all the nails.
4. Below the roof, spray any plants or grass with water to protect them from any runoff bleach that may fall off the roof during the next steps.
5. In the pump sprayer, pour a mixture of roughly 1/3 a gallon of bleach to 1½ gallons of water.
6. Spray the bleach mixture on the roof. The bleach will kill off any leftover moss over the next couple of days.
7. Remove the harness system from the roof.
8. Spray any plants and grass underneath the roof with water again once the process is completed.
Resources:
When working on a roof, safety is very important. Tom added a roof anchor [amzn.to/2S3D991] to the rafters, wore a harness, and used a safety line [amzn.to/2OzVZCx]. These can be purchased at home centers or hardware stores.
Tom used a push broom to gently remove the loose pieces of moss.
He then installed a roll of zinc strip moss preventer, which can be purchased online or at specialty retailers.
Finally, he sprayed down the roof using a solution of water and bleach. He started at the bottom of the roof and worked up so that he wouldn’t step on wet areas and slip.

That’s not really a great method of doing that roof. Soft washing would have been the best way use chemicals and light water. By first sweeping it you’re losing all of the granules. And now we’re hammering more nails into the roof for something that might work

@YankeeWoodcraft Жыл бұрын

Yep. I was cringing seeing him face nail that zinc strip. I'd never face nail metal on a shingle roof. When that roof contracts in the winter, that's going to open up. If they really wanted to self-seal the nails, they could've laid down a strip of ice & water shield first then lay the zinc over that. But even then, I'd never rely on that to keep moss off the roof. I'd just give that roof a wash down every few years as needed. But then again, I'm a roofer. ☺

In my 40 years as a roofer I have never seen moss and the additional moisture it collects make water proof composition shingles water permeable. Moss can hold moisture at the butt of the shingle close to the nailing line, and so close to nails. If the moisture is salty and the nails are not hot dip galvanized, copper, or stainless steel they may rust out. There are indications that some moss inhibiting treatments are caustic to the nails. In general moss growth on a composition shingle roof that is fastened with quality nails is an appearance issue. The sun's UV rays are the main source of composition shingle damage. The north face of a roof may look shabby, but the south face though looking fine from the ground, could be weaping due to lost surfacing, vaporized asphalt, and exposed fiberglass mat.

@monshes 3 жыл бұрын

I noticed my garage roof has green moss on comp shingle butts under trees an a north facing side. IIRC 19 years ago when I stripped the old roof I never saw any real evidence of degradation in that area. I might add that the roof was at least 25 years old and still watertight, roofs last forever in my mild (40-70 degree) climate on the California coast, but since I was doing the house we went ahead and did it all. Do you think the safest bet is to just leave it alone unless it sweeps off? BTW I get the moss mostly from the fog making the trees "rain". I might add I am far enough from the ocean that I can get away with galvanized flashing.

@steveclaasen4130 3 жыл бұрын

@@monshes Sounds like you might be a neighbor. I'm in the Eureka, Arcata area of the California coast. Anyway I have not seen any functional benefit from moss removal. Loose debris and some moss can be removed with a blower, which is less abrasive than brooming. Appearance is a fair consideration in some cases, but moss removal does not promote or increase roof longevity in my experience. I have torn off a section of roof that was fully covered by a flat moss, like a carpet, but found no leaking issue, or water damage. Count the cost of roof maintenance, in time, in money, in effort, and possible danger. Remember even good roofs, properly applied, do wear out, and new ones cost a bunch. My idea is to only do maintenance that will forstall replacement. That would mostly be keeping the loose debris off, and trees/shrubs from overhanging and/or rubbing on the roof. Chimney, and skylight collars should be monitored, and prepped and painted as necessary. Plumbing vent seals, where pipes pass through the cone of the base flashing should be renewed as necessary. I have only seen moss be a contributing factor the one time in 40 plus years, so without further evidence, I believe the worry about moss damaging composition shingle roofs is much overblown, and causes unproductive, possiblely destructive, efforts. Good luck.

I have A LOT of moss on the roof of my shed/shop here in CT. I put in a wood burning stove a little while back and used galvanized pipe to secure the stove pipe to the roof. There are two perfectly clean strips running down the roof starting where the galv pipe is secured. Now, the moss free strips don't run down all the way to the gutter, but maybe 6' down. And the galv pipe is an old soccer goal post and it's, what I'd say, heavily galvanized. I think if I'm going to do this zinc strip thing I'd want to find galvanized strips that are more heavily coated than the stuff they're doing in the video. The concept DOES work though, and that's cool.

I actually have several permanent attach points on my roof that remain in place across the ridge.

@patrickobrien8851 3 жыл бұрын

@Mike Clarke: are the attach / anchor points exposed to the elements, or tucked in underneath the roof tiles? My tiles are glued down front and back - to keep out driving rain in the winter up here in the hills - and I'd have to pry them up; besides which they are rigid and thick, and not like the ones I see in many videos. Last thing: I have a vented ridge-line that is tall and even though I am light (150lbs) I expect it would collapse or buckle were I to have a rope thrown over it with my weight attached... so I'm thinking that I need 2 sets of attach points, one on each side of the ridge-line, which is a pain. (The v-shaped anchor shown here would not be flush with each side of the roof due to the pronounced height of the vented ridge.)

@JerryAndSherry 3 жыл бұрын

Good man! Since I started rooftop work, I've realized that what you've done, permanent ridge attachment points, should have been the first building code requirement ever. Roof work would be a lot safer for a legion of workers. And who thinks it's a reasonable idea to put a bunch of holes in a roof every time you need to go onto the roof? There would be a ton of easily water sealed attachment point designs developed by now, and techniques to utilize the ridge loops to get from gutter to ridge without a typical roof hook ladder.

Someone with experience, who is comfortable on a roof, will be the first person on the roof to set up an anchor point and safety ropes and the last person own after removing the anchor point. If you arent comfortable doing it yourself it is worth calling in a professional. Jacks and planks may need to be used depending on the pitch of the roof in some cases.

Question: What is the most practical (cost benefit) gauge and width for the copper strips? I know that generally speaking the more material the better chance that it will leach and prevent moss growth; but there is a point that it's also an "overkill", particularly when considering the cost of copper; so, I am looking for cost benefit. I will likely do a strip every 6 feet, but am not sure if 24 gauge is best/needed, and 2" wide might not be enough material? Am using it on a north facing roof in a house in the PNW, specifically in the Puget Sound in WA state, and unfortunately the next door neighbors have messy trees... I blow the leaves/fir needles off the roof 3 - 4 times a year... but still need moss prevention mostly on the shaded side..

They actually have roofing nails with a rubber seal around them. Much easier.

thanks for this nice tutorial, that metal plate fastened on the top of the roof to secure the rope, is there any permanent aluminums ones, after use once I don't need to remove it, just leave it on the top of the roof, because I go to my roof once a year to clean it, I don't want every time I go up I leave 12 holes, after 10 years it will be 120 holes , lol

Anyone ever use that zinc strip? Does it work? Tom didn't sound too sure with "it's supposed too".

My Suburu power washer would easily blow the composite shingles right off of the roof. I used the zinc strip as shown here. It definitely did not work. What did work was straight, full strength bleach sprayed on the roof.
