10 Questions for . . . Robert Lenney, Gutter Expert

In this installment of 10 Questions for . . . , Associate Editor Gian Trotta talks with Robert Lenney, a cofounder of California-based Gutterglove and a former certified arborist. In December 2007,  Lenney and partner John Lewis received a patent for their Gutterglove gutter-guard system, which uses a fine stainless-steel mesh stretched across anodized aluminum panels.

You've cleaned many gutters in your time. How should a homeowner start planning the task?
Always think about safety first; don't just go jump on the roof and start tossing out handfuls of gunk. Pick a day when it hasn't rained for a few days; if that's not possible, wait until midmorning, after the sun has dried out the roof.

Do you recommend any special clothing?
I recommend wearing durable pants like jeans and a long-sleeve shirt. Tuck your shirt into your pants—when you're up on a ladder or on a roof, balance is everything, and if a loose end of clothing catches on something, it can cause a fall. Tucking the bottom of your pants into your socks also protects against wasps crawling up your pants leg.

I certainly agree about the wasp hazard; I got stung on my last gutter-cleaning foray. What about gloves?
Leather rather than cotton or rubber gloves give better protection—there are a lot of sharp edges in a gutter. Also, you might encounter some very distasteful substances—pigeon droppings are a prime example—that can cause bacterial infections or leave a lingering smell on your hands. I also recommend some kind of eye protection, either goggles or safety glasses.

When it comes to ladder safety, what precautions do you observe?
There are some precautions to observe with all ladders. Try to set an extension ladder so about 3 feet of it extends above the roofline. While the ladder might feel secure when you step on it, there might be a gopher hole or loose soil under the leg and it could cave in as you climb up. So very lightly jump up and down a few times on the first rung to seat the ladder well before climbing up. If the ladder has a shelf, you can keep a five-gallon bucket on it, securing the bucket with a lanyard.

Inspect the ladder carefully to make sure it's working properly. Be sure the hinge arms on a stepladder and spring hooks on an extension ladder are fully locked. Check that the ladder's rungs and sides aren't  split or bent or loose and that screws and bolts are secure—ladders held together with rivets are usually better in this regard.

(Here are some additional guidelines from the experts at Consumer Reports: Ladders are categorized by weight ratings; we recommend that you get a heavy-duty type 1A. For gutters above 17 feet you should use a conventional extension ladder. Choose a fiberglass or wooden ladder where electricity is a factor, and remember that any ladder can conduct electricity when it’s wet. Extension ladders should be set up with the base 1 foot away from the wall for every 4 feet the ladder reaches up—that's 3 feet at the base for a 12-foot ladder, or roughly a 75-degree angle. For lower gutters, you can use a stepladder or multiuse ladder. No matter which ladder you have, always follow manufacturers directions for setup. For more ladder-safety advice, read our safety tips.) 

What other specialized tools should be used?
Don't use that heavy metal planter scoop from your garden kit or an old spatula. They can scratch steel gutters and give rust and opportunity to form. They can also damage the caulking used on seams of other types of metal gutters.

Those plastic orange gutter scoops sold in stores have one nice quality: Their tips are thin and flexible, so they conform to the contours of your particular gutter style. The downside is they're not as strong as a metal tool, so we go through a lot of them in a season. But the average homeowner should get a few years out of a scoop.

Of wasps and gutter guards

As evidenced by the comments to this September 2007 Q&A on fall cleanup, we receive lots of requests from readers to review gutter-guard systems. You'll be happy to know that we've added gutter guards to our list of products to test.

I've lusted after gutter guards, too, no time more strongly than when I recently hauled out my ladder to clean some debris from my gutters and the area under my elevated deck.

I had a willing helper in my 4-year-old daughter, Thea, who loves to work with me on household chores. But as soon as I propped the ladder onto my deck and rested it against the gutter, Thea let out a sharp cry; she'd been stung by a wasp. I carefully removed the stinger ASAP (some good advice I remembered from our summer-safety quiz) and dashed into the kitchen to mix a paste of baking soda and distilled vinegar to apply to the sting.

As I was searching for the wasp's lair, three of his cohorts dive-bombed me from above. I swatted away one, but two stung me on the chest. Fortunately, some of the baking soda-vinegar mixture was left over. Having had enough of these stinging pests, I ushered Thea inside and donned my sailing anorak, drew the hood and the face mask tight, slipped on some work gloves, and got back to cleaning the gutters—very carefully.

You see, several years ago while cleaning a friend's gutters, I put my hand directly into a wasp nest and got stung on four fingers; it felt as if a lit cigarette was being applied to each one.

So like you, I'm awaiting our tests of gutter guards. I know I'm not the only weekend warrior to suffer injuries—read more in this blog entry—but as they say, once bitten, er, stung, twice shy.—Gian Trotta
