I was the first person in the world to identify that copper prevents the oxidation of asphalt molecules on asphalt shingles. See how easy it is to install this copper in a new-roof installation? CLICK the photo or TAP HERE to order the copper strips.

How Does Copper Stop Roof Moss?

Copper is a natural biocide. It is a natural poison. Copper is used on the hull of sailing ships to stop barnacle growth that slows ships.

Will Copper Make my Roof Last Longer?

Yes. Copper will extend the life of your asphalt shingles. Copper washes onto your shingles and prevents the asphalt from oxidizing.

Read Tim Carter's Roofing Ripoff book where he explains how copper saves shingles.

Above the clean section of the roof, there is a copper cupola. It is this little bitty roof that is keeping the moss off the roof. Every time it rains, a little of the copper washes off the cupola and onto the shingles. That copper creates a poison so that the moss and algae will not grow, must like a weed killer who use on your lawn.

If you do not want moss growing on your roof, you can put copper on your roof. Just place copper strips underneath the cap shingles on your roof. Leave 2 - 3 inches of copper exposed so the rain can wash copper particles down over the shingles.

Or if you are buying a new home or having a roof replaced, there are shingles with copper embedded right in the shingle.

Using a little copper on your roof can prevent moss and algae from growing. It is just that simple.

  1. I have green alge growing on parts of my 10 year old roof. I also see some parts of the shingles going black. Just finished viewing your film clip and was impressed . Thanks for sharing your knowledge and advise.

  2. I have gotten 2 estimates for my garage roof. they are approximately the same price and the shingles will be the same. One indicates that osb will be laid on top of the existing roof decking and therefore cover the holes and the other says the existing decking on top of the roof rafters has be be removed since is is old and rotten and replaced with thicker exterior plywood which will be code and stronger. I have seen that osb board is much cheaper, but will it be as strong as the exterior plywood. It just seems to me, since there is rot on the existing plywood in places as well as the holes, that it should be removed, and the thickness isn't to code. If osb is placed over the existing old plywood the one contractor stated this would be additional thickness to keep limbs from breaking through. What do you think? It is a 900 sq roof and both prices are $3200 to $3500. Is osb acceptable for a roof and will it last as long as exterior plywood, and what thickness is recommended. thank you so much. I have only so much money and can't replace this again any time soon.

  3. HI Tim,
    I have viewed your helpful video about how copper will prevent moss and algae on asphalt singles - my question is will ZINC strips do the same?? I have heard they will prevent moss/algae als0 and cost less than copper..

    I have a hip roof and do you have any recommendation on spacing the strips??? THANKS for all your help!!!!!!! You have a GREAT site.

  4. Hi Tim,
    Great video, thank you. It kind of answered my question as to why a 6 foot wide strip down the middle of my roof was 100% moss free, and there was moss on either side (north facing roof in the Northwest).
    At the very top of my roof was a protruding feature that had a 5'x3' galvanized cap. The roof was moss free for a good 15 feet to the gutter.
    This begs the question of using simple galvanized flashing on the top and any crest on the roof to straddle the crown shingles, using some asphalt adhesive, i would assume instead of nails.
    I have not seen any discussion of this on any web site, however, it would seem an effective and MUCH easier method to install than tucking zinc or copper strips under shingles (which is a reasonable amount of work)

    You thoughts?

    Best regards,

  5. Hi, Tim! My mother in law's home has a roof with architectural shingles installed about 8-10 years ago. The north facing roof sections have extensive moss growth. Will putting copper strips beneath the cap shingles eventually destroy the existing moss or does it need to be removed? If so, is power washing effective? Can Stain Solver be used in a pressure washer to treat the roof before power washing or is it applied afterwards? Thanks for great columns! I look forward to hearing what you bring up and the products/techniques you recommend.

    • The copper will NOT dissolve the moss. You need to brush it off. You can power wash the shingles, but it needs to be done with GREAT CARE. Watch my video about how did it. It's no good to use Stain Solver with a pressure washer. It gets TOO diluted. Watch my video about using Stain Solver to clean roof algae.
