Zinc Roof Strips

zinc roof strips

Over the years, I've been asked more than a few times about zinc roof strips.  Do they work as advertised?  Are they worth the cost?  Are they worth installing? 

Here's my opinion:  No

My reasons:
  1. Look at the picture above.  Obviously, the zinc strip installed at the ridge line is doing something to inhibit the growth of algae on the shingles below it... but not enough to keep algae from growing farther down the roof.  Also, it appears to be doing nothing to prevent the formation of damaging lichen. 
  2. I've long since lost count of how many roofs I've cleaned which had those zinc strips installed.  If they really worked, why was I needed to clean the roof?
  3. From what I've seen, for zinc strips to really work they'd have to be installed every 5 or 6 feet along the slope of the roof.  Along with looking ridiculous, it would be far more cost-effective to just have a maintenance cleaning performed every couple years. 
  4. I think the whole thing is just an aftermarket money grab along the same lines as "gutter guards." 
No thanks.

Somebody recently joked about me looking so much older than the younger man in some of my YouTube videos from years ago. Well, like Indiana Jones said, "It's not the years; it's the mileage." But with thousands upon thousands of hours spend outside cleaning - and along with the aching back, creaking knees, and throbbing right shoulder - comes the benefit of experience and breadth of view. I've seen things come and go over long enough periods of time to notice trends in the exterior cleaning industry. In this blog I'd like to share an observations regarding one of those trends. First, it's important to realize that the exterior cleaning market on Cape Cod is vastly different than nearly all of the rest of the country, because our roofs and siding materials are vastly different. Most residential construction in the U.S. features siding of vinyl, composite, or mayyyyybe painted wood. Roofs are almost always asphalt/composite. The bare cedar surfaces found so commonly here on roofs and siding are very, very rare in most of the United States. We are a tiny, tiny niche market. Similarly, the exterior cleaning industry on Cape Cod is necessarily different from the exterior cleaning industry elsewhere, where those hard, synthetic or painted surfaces are readily "soft washed" with a chemical solution dominated by sodium hypochlorite (i.e. bleach). While sodium hypo - or "SH" in industry parlance - is a fine and appropriate ingredient for cleaning many hard, non-porous surfaces (vinyl siding, "Hardiboard," tile roofs... I'm looking at you, Florida), SH simply isn't the do-all solution when it comes to cedar... especially the WHITE cedar so prevalent here on Cape Cod. Don't get me wrong: chlorine bleach does has its place in the local cleaning toolbox, but the toolbox necessarily contains many other tools as well. Companies such as Harwich-based Wash Safe set the standard years ago for non-chlorine cedar cleaning products, instead relying heavily on the cleaning power of sodium percarbonate ("hydrogen peroxide")-based cleaning chemicals. These non-bleach cleaning chemicals required different cleaning equipment and processes than the rest of the country was using to clean everything with bleach. Because our local cleaning needs are so unusual and insignificant compared to the nationwide industry as a whole, the ever-increasing number of companies who make fancy trucks and trailers for the exterior cleaning industry have never been motivated to make products designed for our niche ways of cleaning. So, on a national level, the equipment being marketed to the exterior cleaning industry has been nearly entirely designed for those who clean with bleach. For this reason, the experienced cleaners on Cape Cod have long since resorted to designing and building their own custom "cleaning rigs." I did the same. So, for years, one observable trend has been for cleaning equipment to become ever-more tailored to the legions of "Bleach Bandits." Pumps were built to be more and more resistant to SH's corrosive effects; synthetic bleach stain-proof clothing was marketed to cleaners; metered mixing manifolds allowed the fine-tuning of the bleach application. Then, the mixing valves became controllable with a little key FOB from your position on the ladder. Bleach, bleach, bleach. . But change is in the air. Happily, in this one little way at least, the change is a good thing. It seems that us niche wood guys are starting to be heard by the broader exterior cleaning industry. Many chemical vendors have added sodium percarbonate to their lineups, making their own version of "Wash Safe Cedar Wash." Even better, sodium metasilicate (the EPA's preferred replacement for trisodium phosphate, or TSP) has crept into common availability such that even companies in the very heart of bleach country are now offering their own sodium metasilicate-based wood cleaning formulations (looking at you, Southeast Softwash ). Today, the wood-cleaning crowd is being heard by even some cleaning equipment makers. Case in point: yesterday, I met with a young cleaner off-Cape who is adding a fancy, factory-build cleaning trailer to his small cleaning fleet. AND, to my delighted wonder, along with the typical bleach-slinging tools, the trailer included a tank labeled for (gasp) sodium percarbonate! I couldn't have been happier for him or the industry. Including more tools in the tool box, and thereby recognizing that bleach isn't the right tool for every cleaning situation, is a step in a better direction.

Leah says that I'm old-fashioned; that more and more people conduct business communication via text message; that by not being a "texter," I'm missing out on potential customers. I say: that's all true. And I won't change. Here's why I won't embrace texting for business: Overwhelming volume. Thanks to a simple promotional video which I made and threw on YouTube back in 2017 - which has since been viewed around half a million times - my cell phone gets carpet bombed with texts all day, every day, from people all over the world all asking questions about exterior cleaning. I wake up to a dozen texts from numbers I don't know, from places I've never heard of. By lunch, another dozen. By the time the day is over, another couple dozen yet. Everyone has a question, and almost nobody (really: nobody ) is a simple answer away from having the info they need. The time needed to respond to these questions just doesn't exist. I know, because I tried for years to keep up. One question leads to another, and each answer is time out of my own day and life which I'll never get back, and for which I get nothing in return. No organization. Unlike emails or actual paper mail, there remains no good way to track and organize text messages. "Pinning?" "Flagging?" Oh, please : try readily organizing and tracking fifty or a hundred new text conversations each day. Try scrolling back through these silly little phone screens with aging eyes to look for that conversation with somebody - can't remember who - about that chemical they asked about. It's always an emergency. The nice thing about roof cleaning and exterior cleaning in general is that there really aren't any "urgent" situations: moss, algae, and lichen grown very slowly and predictably. ("Look out! A glacier is coming!") When these things are noticed, it's easy and reasonable enough to put it on the schedule to address when we're able to. Maybe that's in 2 weeks, maybe that's in 3 months. Either way, things aren't going to change much in the meantime. BUT, there's something about texting which brings out the last-minute crowd: the Realtor who just realized that a home is a dump and photos are being taken on Friday; the exterior cleaner who bid on a job, got the job, and only now - while doing the job - realizes that he doesn't know what the heck he's doing. People in these situations seldom call, but they DO text! By not getting into texting, I'm sidestepping the drama which comes from last-minute, ill-planned cleaning. No sense of people. When I speak with a potential customer on the phone, I can get a decent sense of who they are, whether their expectations are realistic, etc. Tone of voice is more meaningful than emojis. There are some "red flags" which I look for in a potential customer which will cause me to politely decline involvement in a cleaning project: them badmouthing every contractor on Cape Cod, or them saying they want things done the way they read about on Reddit... even if they have no idea what they're talking about. Again, a short conversation tells me far more about a potential customer than a text exchange, and I imagine that they could say the same in reverse! Want to get in touch? You can find me here .

This past week I was driving down Route 28 in Harwich on my way back from a job in Dennis. Suddenly, the smell of chlorine bleach hit my nose with the force of a slap. My god, it was overwhelming ! And where was it coming from? My first thought was that my 5 gallon container of 12% sodium hypochlorite in the back of the Hino had somehow broken loose and busted open, spilling all over the place. But that didn't make sense - I wouldn't smell it so badly if it was behind me in my flatbed as I drove down the road. Then I realized that other drivers coming towards me were covering their noses and mouths as they drove. The smell was coming from somewhere outside my vehicle. Two blocks later, I found the source: two guys were washing a white picket fence... with a high-volume roof pump . One was literally shooting a firehose-like spray of bleach solution at a right angle to the fence (and overshooting into Route 28) while the other frantically hosed everything down with water. As I watched a car drive through the bleach mist, two things occurred to me: Damage from "overspray" is the most common reason for liability claims in the exterior cleaning industry. These guys probably weren't actually idiots, but rather they probably hadn't been trained properly or been doing the job long enough to realize their errors. Which got me thinking about something else: I have seen so many examples of bad practice in this industry over the years, and I've taken pictures of many! So, with these thoughts on my mind, I decided to make a video showing the results of poor cleaning procedures, and to share my thoughts on how these poor results can be avoided. That video is below; I hope somebody learns something and that some costly or dangerous errors are avoided.

Thesis: The exterior cleaning industry is dominated by pushy, shady, up-selling companies which pawn off questionable products using fear-based sales tactics. Exhibit A: Yesterday in Yarmouth, I looked at an asphalt (composite) roof for a homeowner who thought it might need a cleaning. Yes, it does: dark streaks of algae discolor the north side of the roof, while spots of moss and lichen are plainly visible. Easy enough. After looking at the roof, I noticed that the white cedar shingled siding didn't look quite right. "Oh, that ," said the homeowner. "Don't get me started!" Of course, I did. As the homeowner explained it, several years ago she had hired a well-advertised local company to clean algae from the siding. The salesman/owner insisted that the siding not only be cleaned, but also treated with their revolutionary stain/sealant product which would be a one-time treatment. Must. Be. Done. Basically, to do anything else would be sheer madness! So, the homeowner hired said Company to clean and "seal" the siding; the Company massively over-promised and under-delivered; the company later got so many complaints that the Company dissolved and re-formed under a new name. Clean slate! And today, while that Company's glossy print ads and prominent Google ads are seen by thousands, they're still peddling the same crap to unsuspecting cedar customers, and the Yarmouth homeowner's siding looks like this all over:
cost of cedar, cedar siding

To a large extent, my livelihood is tied to the cost of cedar. For example, if cedar roofing and siding were free, I'm guessing I'd be un employed because nobody would care about maintaining something which is free to replace. At the other end of the spectrum, if cedar roofing and siding cost the same as, say, gold ... well then I'd be busier than I could ever keep up with. There would be a flood of new cedar cleaning services in the industry. Cleaning equipment and chemicals would be wildly overpriced. As it stands, cedar costs less than gold but it's far closer to gold than "free." For this reason, yes, there continues to be more new cleaning services each season, and equipment and supplies are indeed priced to the moon. HOW costly is cedar at this moment? Let's look at Home Depot , which should be considered the bottom end of things but which I'll reference because most higher-end yards don't publish their prices online. Home Depot's white cedar shingles are available for $69/bundle plus tax. A bundle covers 25 square feet, so that's just about $3/square foot. But, obviously, that's just the outermost materials. If a homeowner is having siding replaced, then the material cost is just the beginning. Don't forget about: disposal of the old siding stainless siding nails new cedar breather and water resistant house wrap and the big one: LABOR to remove and install Siding is commonly measured in "squares," whereas each square is 100 square feet. So the above-mentioned bundles of cedar are 4 bundles per square. Add all this up, consider that the above example represents the rock bottom end of the price spectrum, and it's no wonder that us cleaners are able to clean cedar for a tiny fraction of its replacement cost. That's my idiots such as myself are as busy as we are. Here's a number I'll never forget: A contractor recently told me that they price out new red cedar roofing installations at $2000/square. That's $20 per square foot .
