Great job and a great tool to have to talk people out of zinc strips.

Michael Derose · SoftWash Systems Certified Applicator

Nice job. I like the before and after.

Thanks guys, I think since they had the zinc strips it made for one of the most dramatic before and afters that I can add to my portfolio.. I can't tell you how many people I have at home shows ask me about the zinc strips..

Nice Work Lee. I would love to use that picture if you allowed me.
Everyone asks about zinc strips, but seeing is believing.

Just an FYI the zinc strips do work if they are installed every three feet all the way up the roof, just installing them at the top ends u with results as you see in his before picture.

I tell people that Jim, but it still wouldn't be guaranteed and the cost would likely cover 2 roof cleanings.

Some zinc shield manufacturers recommend installing them at the peaks and promote only intermittent strips if the runs are greater than 20 feet. They also state that they will last 20 years under normal conditions, but do not state what normal is. They also state that 20 years is the typical lifespan of an s asphalt shingle roof, which is for the old cheap three tabs. As we all know shingle manufacturers offer 30,40,50 and lifetime warranted shingles. The zinc is a novel concept, but not terrible practical. The zinc strips in certain parts of the country can also void any home owners claims due to high wind shingle damage, because ou have added another layer that can cause premature peel and shear lift.

Not a problem Danny, go for it!

The zinc strips in theory sound great, however they would need to be installed every 3 feet down the roof ( that would be a ton of money, and it would look like you have metal sticking out of your shingles every 3 feet until they weather in)

The main problem is that they are designed to work when rain carries the zinc down the shingles.. For 1 ( For every foot after the first you are losing about half your dilution) therfore after 3 feet you are back to 0% concentration.. For 2. The rain is supposed to evenly take the zinc down the roof.. As a roof cleaner I have been on ALOT of roofs, and I have never seen one that is exactly flat, you all know what I mean either the stringers are a little higher than the adjacent ones or warped boards under the shingle which result is minor riges, water is going to take the easiest and fastest path down the roof, which means even if the zinc was strong enough to work, you would still end up with streaks..

I think having zinc strips every three feet down your roof would look worse that the dirty roof it's self. This is easy to sell against and is very costly to do. As well in many states requires a roofers license. I'd stay away from zinc strips.

I am not promoting the zinc strips, I am all about softwashing, I just wanted to let you know they do work and only an 1/8 to 1/4 inch is exposed they do blend in after weathering. You all know where there is any kind of galvanized flashing, there are no roof stains in those areas. Adding them to an existing roof would be costly and have the potential for a future leak and you most surely would need a license in every state to install them. Oh this discussion is giving me a brilliant idea! Off to the drawing board. ;)
