they will only last about 7 to 10 years long and you also have to put them every 8 feet down to get the proper effectiveness.... copper last much longer and does a better job just cost way too much money ....

Fungal resistant shingles are shingles with either zinc or copper granules in them, spread throughout the agrigate. They fail all of the time.

We cleaned algae resistant shingles, the HO had told me they were 4 years old! He had been reimbursed by the shingle manufacturers.

Hey guys you gotta look at my spelling. Actually Josh they need to be every 3' to be somewhat effective. Its much more cost effective to pay a SWS certified Roof Cleaner 3-4 times over the life of the shingles. plus all the extras we bring to the table, gutters siding etc...
For those customers who ask about zinc strips here are some pics to show their true effectivemess!
