Get Rid of That Funky Roof Mold

Have patterns of strange, streaky stains appeared on your roof this spring? My phone rings off the hook for roof cleanings this time of year, and as I drive around town, I see so many houses decorated with unsightly roof residue, which frequently emerges during the April rainy season. But what are the stains, why have they suddenly popped up, and what can you do to get rid of it? They are all good questions, so let’s get you some answers.

Stains on the roof are generally algae, which gets carried by wind or birds from roof to roof, and may not be visible until they have enough moisture, heat, and humidity to grow and spread. The manifestation of an algae problem is those black streaks that you see. Now don’t be too alarmed, algae isn’t necessarily going to ruin your roof immediately, but it does affect the curb appeal of your home and the problem could end up damaging and pulling up your shingles if not dealt with for a long period of time.

An interesting fact is that copper, zinc, and lead are toxic to algae, and many newer roof shingles contain copper granules, which act as a barrier against any mold growth. Homes with older roofs won’t benefit from this technology, but it explains why you won’t see algae where metal flashing has been installed. If you’re susceptible to algae and in the market for a new roof, be sure to inquire about this type of shingle.

So now that we know what it is, how do we get rid of it? The easiest way to rid your roof of algae is a good cleaning solution, which can be picked up at the hardware store, applied using a pump sprayer and rinsed with the garden hose. One tip is to give any plants below the roof a good drink of water beforehand so they don’t absorb the solution. If you’re not comfortable on a ladder, call a professional to help you complete this task. A clean roof isn’t worth a trip to the hospital, and a local area home improvement specialist will be able to complete the job in just a few hours.

Once the roof has been cleaned, you might want to do something to prevent the mold from coming back again. As I mentioned, copper, zinc and lead-coated sheet metal are toxic to algae, so installing a strip of flashing will help stop that nasty fungus in its tracks. Choose a strip that’s at least six inches wide, and have it installed at the roof peak to ensure that the metal molecules wash down with the rain and protect the roof from mold build up.

Spring Lawn Care Tips During a Drought

This week’s short patch of warmer weather probably had you thinking about your lawn and wondering what you can do prepare it for summer while the city is still under mandatory water restrictions. Our drought status isn’t likely to be updated until at least May, so in the meantime, I thought it would be a good idea to give you a few tips on how you can try to preserve your grass as we continue through this dry spell.

Of course, grass needs water to grow, but outdoor watering right now is not possible, so first let’s focus on the soil. Healthy soil is key for root systems to grow and with proper aeration and management, soil can actually retain moisture incredibly well. When water is scarce, roots will dig deep to find the nutrients that they need. If they can’t find what they are looking for due to compaction, low pH levels, or layers of dead materials, the roots will start to die off and you’ll find yourself with a brown lawn. However, if your soil is in good shape, you don’t need to water your lawn as much, regardless of our drought status. Here are most common methods of maintaining good soil.

Topdressing is the application of a thin layer of compost to your lawn. The nutrient-rich composition of organic matter in compost can give your lawn the biology boost it needs to stay strong during drought conditions.

Aerating is a method by which a homeowner uses a machine to punch small holes into the lawn, allowing air, water, and nutrients to reach the roots of the lawn easier. This is an excellent practice during drought times as it allows what little precipitation we may get to reach the most important part of the lawn faster.

Dethatching is the process that removes old and dead organic materials such as leaves from your lawn. The long winter generally kills anything that isn’t attached to roots, and these materials can get compacted into your lawn, placing a barrier between your grass and the sun, air, and water it needs to grow. Removing the thatch is key to let the new, living material get to the surface.

Once your soil is in tip-top shape, you can decide whether to try and preserve the grass you have or look for a drought tolerant alternative. If you’d like to try and keep your grass until the drought lets up, mow it as infrequently as possible and cut it at the highest setting on your lawn mower.

For those who are interested in drought-tolerant grasses, some of the most popular warm season varieties include Bermuda grass, Zoysia grass, and Buffalo grass, but each variety performs differently depending on the amount of sun and traffic they get, as well as the soil composition.

Hopefully, we won’t need to worry about drought tolerant lawn care in the near future, but if you are looking to make a major change with your landscaping, always consult with a professional who can help you choose which solution is right for your needs.

A Spring Cleaning List to Tackle Your Home

Even though today isn’t much of an indication, it seems like the warmer weather should finally be arriving, which means that it’s time to dedicate a weekend on your calendar to a spring house cleaning.

Spring cleaning is a dreaded task for many people, but I think it’s a great opportunity to go through your home and look for any small problems or maintenance issues that can cause you headaches in the future. I also use it as a time to sort through closets and storage to donate clothes, sports equipment, and tools that I haven’t used in awhile. But when it comes to cleaning, there are a few places around the house that might get missed in your more regularly scheduled tidying up. Here’s a list to help you tackle this tough project:

Windows: You might give the insides a friendly wipe down all through the year, but cleaning the outside of your windows is a smart job to tackle now, especially if you live near the road or a high traffic area. Getting to second-floor windows might take some work on a ladder, so use caution and take your time.

Cabinets: From afar they probably look clean, but they are most likely splattered with cooking oil, tomato sauce, and all those yummy soups and stews you’ve been whipping up all winter. Use a cabinet cream to remove all the built-up gunk while conditioning the wood at the same time. I like the Parker & Bailey version.

Appliances: Just like the cabinets, your appliances can get streaked and spotted with cooking remnants, so give them a good wipe down to keep them looking like new. If you have stainless steel, make sure you look for a proper polish like this one from Weiman, or if you want to DIY it with a non-toxic solution, you can use a mixture of vinegar and oil.

Countertops: Have you notice stains on your granite? This is a surefire sign that they aren’t sealed properly. When you have them installed, make sure they are treated with a sealant a few times, and then make it a once a year project. If water or liquid forms a bead on the surface of the counter, you’re good to go.

Dishwasher: You might think this appliance is the cleanest place in your kitchen but smelly food particles can get stuck to its interior, which can then end up back on your dishes. Remove any large pieces of debris from the bottom of the dishwasher and then run it on the specialty cycle using a special dishwasher cleaning liquid.

Wood Floors: If you’re vacuuming and mopping your floors every week, this cleaning routine might be doing them more harm than good. Wood needs to be conditioned in order to help it retain its normal levels of moisture. Nix the wet washing and try applying a wax sealant every few months to keep them looking shiny and new. There are different types of waxes depending on the type of wood you’re dealing with, so pop into a home improvement store and ask a professional for some advice before tackling the job.
