Save Your Roof!

Living in the Pacific Northwest grants us access to amazing landscapes, lush green forests, beautiful mountains and gorgeous coastlines. For our roofs, though, it comes with a price. Moss. Proud ofseattle home inspection moss covered roof hall of shame that 30-40+ year asphalt roof you paid top dollar for? You should be, it’s a beautiful product and adds value to your home. But, do you know how to care for it when it comes to moss growth? Moss grows slowly and therefore we don’t really notice it as readily as say… a leaky faucet in the bathroom you use daily.

There are many ways to retard the growth of moss on your roof; zinc detergents, zinc strips, baking soda, bleach, power washing, etc. I’m not here to talk to you about the different ways to keep off moss. I’m here to talk to you about the two items listed above that do more harm than good.

Lets begin with Zinc. An element. Something that is already in it’s purest form and does not break down. The zinc is toxic to moss and thus, works brilliantly. However, an Oregon State University study found  zinc is also toxic to fish and other aquatic life downstream. Going as far as to say “Though this product is supposedly safe for surrounding plants, it is toxic to fishes and aquatic invertebrates.  Do not apply this product to water or let the product come into contact with water sources.” which is kind of hard to do when you put it all over your roof and allow rain to wash it down the drain.home inspection seattle why not to power wash your roof

One of the most common forms of moss retardant is power washing. While the immediateness of the results and the profound visual difference power washing can have could cause a person to think it’s a good idea… it’s not. Time and time again I find myself on the roof of a house that has been put-up for sale, snapping picture after picture of pressure-washer damage. Your roof, while able to resist the constant impact of the elements, can not resist a hard, directed, pressurized jet of water pointed directly at it. Bundle this with the fact that moss has been compromising the roofs integrity for years as it was allowed to develop and you’ve got a recipe for disaster.

In conclusion, when considering moss remediation and removal, it’s important to take into consideration the which types align with your desired result. There are zinc strip products that claim they are non-toxic to aquatic life. There are roof-power-washing companies that say they won’t damage your roof. My advice to you? I personally chose to treat with non-toxic products that have literally zero negative side effects, like baking soda. Oh and I never, never recommend power washing, ever, seriously, ever, they’ll wreck your shi-ingles.


Are you the next victim of a burst?

Here’s to hoping your rubber wash machine hoses don’t burst in the time between reading this article and getting them replaced. On inspections we frequently make this call out …and for good reason. If you’re like most people: you know someones who’s wasHall of Shame Abode Analysis Seattle Home Inspectionh machine hoses have burst and flooded a portion of their home. When taking the cost of a home into account, why do we skimp here so frequently?

I recently inspected a home for a client who had an inspector tell her to upgrade to metal braided hoses. Unfortunately she didn’t take his advice. Flash-forward 5 years – I gave her the same advice. She shared her story of learning “the hard way” the devastating effect of a hose burst while she was at work. She insisted she would not be making that mistake again. 

For a difference of approximately $10 you can nearly eliminate the chance of your hoses bursting. Rubber hoses are rated to about 700psi or so, where as metal braided hoses are commonly rated to 1500psi or greater. In addition, many metal braided hoses come with a 90° angle on one end to relieve the highest pressure area and allow you to push your wash machine closer to the wall. Many metal braided hoses come with a lifetime warranty vs rubber hoses which commonly offer a 1 year warranty. When you’re looking to purchase your next home ask yourself “is it worth the extra few bucks?” – yes, my friend, yes it is.

Dielectric Unions/Dissimilar Metal Contact

Seattle Home Inspection Andrew Grimm 4252987382 Abode Analysis Seattle Home InspectorsAt Abode Analysis, we don’t overlook the small details. Many may overlook something as innocent looking as this; have you sighted what’s wrong here?
Think “battery”. Dissimilar metals are a looming, underestimated problem commonly found in a home and is surprisingly easy to resolve.

Metal and galvanized steel should not be used in the same application. To connect the two, you can use a dielectric union, which connects the two via a rubber gasket to ensure the two metal’s don’t interact with one another.

If left unnoticed for a long period of time, the two metals will create electric current and compromise each other to the point of corrosion and possibly catastrophic failure. Our clients appreciate our attention to detail, especially the minute details which help ensure the security of their purchase far beyond their move in date. This can be easily remedied by a home owner as a DIY project, using correct supportive materials. Give us a call or schedule your home inspection online today. 425-298-7382
