Shoes for Walking a Cedar Roof

Korkers are a good tool to add to any roof cleaners arsenal. They are shoes with spikes that grab ahold of extremely slippery cedar shakes. Cedar shakes are like ice when they are wet and its a GUARANTEE that a cleaner will be headed for a long fall without some measure of safety. I would venture to say that walking a cedar roof is nearly impossible even in dry conditions!

In the picture below the wearer of these shoes is walking a roof of  7/12 pitch with no problems. Although korkers are a necessity for safely cleaning cedar roofs they do not take the place of necessary safety devices for fall protection such as:

  • Lanyards
  • Safety harness
  • Roof hooks
  • Chicken ladders
  • Safety engineered rope

Moss on Roof

What You Need to Know about Preventing Moss On Roof

Roofs that have a porous surface, such as wood and asphalt shingles, have a tendency to develop moss on roof. What can you do to prevent this happening to your roof? If you don’t want to replace the roof, you should clean the entire surface with gentle raking and then treat the roof with a chemical treatment  mixed correctly and done by a professional. This sort of care, performed regularly can work very well to remove moss on roof and prevent its return.

If your existing roof is of a material that can be painted, there are types of paint that have a metallic or mineral content that will help deal with the problem of moss on roof. Again, this is a solution that will have to be tended to regularly.

Your roof has a tremendous amount of exposure and takes a beating from the elements day-in and day-out. Any maintenance measures or treatments used on your roof will need to be repeated at least annually and possibly two times a year, dependent on the shade and vegetation your home is surrounded by.

In the long run, the best thing to do to prevent moss on your roof is to start out with a roofing material that is moss resistant. Among moss resistant roofing materials are chemically treated shingles that are algae resistant and metal roofing, such as aluminum sheeting, galvanized steel and copper. In fact, metal roofing is so effective at preventing moss on roof, that the addition of metal strips to the peak of a non-metal roof will help kill off existing roof moss and prevent it from returning.

If you don’t like the idea of metal roofing, you can get specially treated roofing shingles of a variety of types that will help control moss problems. Shingles that are intended to deflect moss on roof are called AR Shingles. The acronym stands for “algae resistant”. This type of shingle material is treated with granules of copper or zinc to retard moss growth. When it comes time to replace your roof, be sure to look for materials with the AR designation to help keep the moss off your roof.

 

Seattle Gutter Cleaning

Seattle Gutter Cleaning

Seattle gutter cleaning is a job that needs done at a minimum of one time per year. Homes that have trees that overhang them, should consider performing the chore, twice a year. Here are some serious reasons why a homeowner should consider cleaning their gutters:

  • Fascia Boards will rot if water overflows the gutters.
  • Water intrusion usually happens from problems starting at the gutter line.
  • Water intrusion can start with a pinpoint leak and make its way from the roof to the landscape.

For the amount of problems not having your gutters cleaned cause, the price of the service is very inexpensive. Costhelper lists the service at under $225 throughout the nation. The price for a Seattle gutter cleaning as listed by us is:

Size of Home*denotes: square feet Stories of Home Price Additional Charges* 2 or more stories
1500 SF 2 $110 +$40
2500 SF 2 $149 +$40
3000 SF 2 $199 +$40

Many homeowners don’t realize how important the chore is and postpone it. Damages can occur rapidly to a home, with overfilled gutters. Areas of the home affected are:

  • Drywall
  • Foundations
  • Siding
  • Landscape

Comparing the price of gutter cleaning to having any of the above repaired, we take a look at some cost comparisons provided by different sources:

Bleach for Killing Moss on a Roof

Leave a comment

WHY STORE BOUGHT BLEACH ISN’T STRONG ENOUGH TO KILL MOSS

There is a common misconception that bleach can kill moss. Homeowners go into their local supermarket and pick up a jug, pour it on their roofs and wonder why the moss hasn’t died. This information is faulty because, originally, store bought bleach only contained 6% of its weight as Sodium Hypochlorite [A.K.A Bleach].

6% bleachMIXTURES AREN’T ALWAYS SO CLEAR

There are many faulty ehow recipes on how to mix the bleach. By the time you’re done with even a conservative, 1 part bleach to 3 parts water your mixture isn’t strong enough to kill the moss you were after. Mixing household bleach which originally held 94% of its volume as water with even more water makes for a product that is not potent.

Bleach is about $6 a gallon at this time of writing. It takes about 40 gallons of liquid to properly cover an average homes roof.The roof cleaning costs quickly add up.

Let’s take a look at how easy this can be to screw up, and how difficult it can be for an average consumer to properly and correctly clean his roof:

Original Amount of 6% Bleach

Amount of Water

Strength after Dilution

Gallons of mix required for average 1200 Square foot home

Gallons Total:

1 gallon

33%

4%

40

Bleach: 30 g

   H2O: 10g

You now need a surfactant (something to stop the mix from rapidly flowing into your gutters), Dawn* soap or any surfactant able to mix without causing a reaction to bleach, work well. This is a surfactant that works well with bleach and doesn’t take away from its shelf life.

The mix above is a standard mix roof cleaners use to kill moss. Many times depending on the bleaches shelf life, the mixtures need to be adjusted. Bleach is a very volatile solution that loses its strength quickly and doesn’t handle well with a whole host of surfactants. Mixing the wrong surfactant can be wasteful and leave you with a mixture that doesn’t do what it was supposed to which is to:

  • Kill Moss.
  • Remove Stains.
  • Not Damage the roof it is applied to.

We’ve covered everything except how to get 40 gallons of liquid onto your roof ……. [Continued shortly in: pumps for roof cleaning]

Black Streaks on Roof

Chemical Cleaning to Remove Black Streaking from Roofing

Gloeocapsa Magma is the scientific name for those black streaks on your roofing. Gloeocapsa is a form of algae that lives in wet humid climates. These streaks of black are not as evident in the Seattle-Tacoma region due to the majority of roofing material being of dark coloring. If your roofing substrate is light colored, it’s very probable that these stains will be found on your home.

Although, Gloeocapsa Magma is not harmful to roofing, the appearance of a home suffers tremendously. When selling a home the algae stains should be an issue that is dealt with before the home is placed up on the market. These stains are a red flag to potential home owners who may not know exactly what that black stuff is and whether or not it’s harmful to the roofing.

Soft wash roof cleaning with chemicals is a superior method of removing Gloeocapsa. This method of roof cleaning gets rid of these unsightly black streaks while keeping the integrity of the roofing intact. Power washing is not as effective at eliminating Gloeocapsa. It is also very damaging to roofing shingles. Read more here………….

In the picture to the left, a chemical solution is sprayed on the roof. Each chemical in the mix does a certain job. Within 25 minutes, the picture to the right shows the roof stains are almost completely gone. The mix continues to work on the stains and streaks until the next day of rain. After the roofs first shower, the roof is looking its best.

Going from being a white roof covered in black to being a white roof again has strong selling value for a home. Soft Washing is a great way to safely and effectively remove black streaks from your roof in Seattle. Whether your home is up on the market or you just don’t like coming home to a dirty roof, consider chemical cleaning when hiring a roof cleaning contractor.


 

Cedar Roof Oiling is it Necessary?

Leave a comment

Why Should I Oil My Roof?

 There is a big debate on the benefits of oiling a cedar roof. A comprehensive and great research paper was written by OSU students, referenced in EC1271, September 1988. Their exhaustive research neither discounted nor encouraged oiling of cedar roofs. As stated in EC1271, originally Cedars mass only contained 3% of its weight in oil. With such a small percentage of its weight to begin with being oil, the debate on replenishing is faulty.

 We are not stating that the oils should be replenished. We are advocating oiling a roof in Seattle to prevent rapid expansion and contraction caused by UV rays and rainwater. The stress of shrinking and enlarging cause wood to crack, it is our belief, that oiling a roof stops the expansion and contraction from causing damage to the shingle. The oil allows natural contraction to happen without stressing the wood it is applied to.

 

What Product to use when Oiling a Cedar Roof in Seattle?

Chevron shingle oil is a superior product for oiling cedar roofs it is of low velocity and transparent. The application doesn’t change the appearance of wood; instead it gives the wood a wet look. Although higher in price then other cedar oils, the history and its long established reputation amongst wood restoration experts make it possibly, the best choice for oiling a cedar roof or fence. There are many benefits of Chevron Shingle Oil such as:

  •  Its established reputation.
  •  Its ability to mix well with solvents.
  •  Its lasts when applied: many homeowners have said their oil treatment lasts 5 years or longer.
  • It’s easy to apply. A backpack sprayer with a round tip or flat headed tip work great. There is no need for paint sprayers.
  •  Its ability to be mixed with stain.

5 gallon pails of Chevron Shingle Oil

Why Chevron Shingle Oil?

 Its long established reputation is a major factor on why this is our product of choice. We have used other oil products but they don’t lay down as well as Chevron. When mixed with a solvent at 1 to 5 gallons of shingle oil the flow of the oil is even. The vast majority of a roof can be covered in one solid, thin application. A major problem when oiling a cedar roof is over application that clogs the pores of the wood. The oiling needs to be laid down evenly and uniformly in a thin manner. Chevron in our experience, when mixed correctly, accomplishes this.

 When deciding to oil your roof, it should be done from the day it was installed. The ability to repair a cedar roof once the damage has been done is nonexistent. Maintenance is major issue for wood roofs. There are ways to treat cedar for moss that differ greatly from the way we would treat a composition roof. On average a 1200 square foot roof area costs from $16,000-25,000 dollars, according to homewyse. Yearly maintenance can run you about $400. When deciding to purchase a home with a cedar roof or having it installed, budgeting for maintenance should be the first thing you do. The unexpected consequence of not maintaining your roof, can seriously hinder your economic circumstances.
