Seattle-Bellevue Roof Cleaning Photos

1 Comment

Most people seeking a roof cleaning,cedar roof restoration or deck restore do some research on a business before actually calling. Seattle is home to the most tech savvy consumers in the nation. Bellevue is home to many professionals who are accustomed to diligently checking references and using friends and family as their source for home improvement recommendations.

The saying goes that a picture is worth a thousand words so this post will focus on photos taken by 1 of our 3 crews to help serve as a reference to how we clean roofs, restore decks and bring back to life cedar roofing:

 

DECK RESTORATION BELLEVUE

BEFORE DECK CLEANING BELLEVUE,WA

This deck was covered in algae. It took 3 washes with oxygen bleach and an oxalic acid treatment to restore it.

Here the power of experience comes into play. The use of per-carbonate cleaner before a power-wash was the only way to effectively remove the deep stains. A light coat of sodium hypo helped kill moss.

The final step in a restoration is applying an oxalic acid treatment.

The restoration of this wood deck that had very little maintenance took  4 different chemicals and 6 hours. A dramatic difference from the photo above.

ROOF CLEANING SEATTLE

BEFORE-ROOF-CLEANING-SEATTLE

This roof had moss growth over its entire surface. We manually scrubbed and then applied moss killing and stain inhibiting chemicals.

Composition roofing is an inviting environment for moss growth in Seattle. Make sure to not destroy your roof while having it cleaned! We NEVER use power washing on asphalt/composition roofs.

After manual scrubbing, a moss and stain removing chemical mix was sprayed on this home in Seattle.

Using the soft wash roof cleaning method can clean a composition roof without destroying it. The difference in the pictures couldn’t be any more stark. All our roof cleanings come with a one year no moss warranty.

CEDAR ROOF RESTORATION BELLEVUE

Before and After Cleaning-Bellevue, WA

This roof in Bellevue, Washington was restored in a 5 step process. The roof was oiled to prevent cracking and warping during the cold winter months.

Cedar roofs are some of the trickiest projects to undertake for a roof cleaner. Safety and using the right chemicals are serious concerns. The roof above was suffering from severe weathering and the photo above was snapped mid way during the cleaning process.

Bellevue Cedar Roof Restore

After a thorough cleaning and acid wash this cedar roof was oiled to prolong the cleaning process.

Oiling a cedar roof deflects the harsh winter months we face in the pacific northwest. Choosing the right products and adhering to a maintenance schedule can lengthen the life of your cedar roof in Bellevue, Washington.

CONCLUSION

Trusting recommendations can go a long way in choosing the right contractor . We hope the photos above served as a reference to what we do. We have serviced over 200 clients in the last year and have many referrals upon request.

Deck Restoration Seattle

Old Weathered Decks can be Restored

Wood deck restoration in Seattle is the process of bringing back the natural appearance to wooden structures such as cedar roofs, cedar decks, gazebos and patio furniture. The climate in Seattle is wet, damp and lacking in sunlight; this leads wooden decks to develop:

  • Moss, Fungus and Lichen.
  • Micro cracks from the stresses of constant rain and sporadic sunlight.
  • Weathering: wood uses weathering to protect itself from our climate.

Although your wood deck in Seattle may look like it needs replacing, most of the time a restoration can bring it back to life. The process of wood restoration is accomplished using certain tools and chemicals and done in a certain order. The first step would be a survey of the structure to be restored.

The Survey

Before starting any restoration project a survey of the structure must be done. Some common questions asked by wood restoration experts are:

  • What type of wood is the deck, gazebo or roof made of?
  • What type of maintenance was previously done? If the wood structure has been previously stained, a different procedure would be called for.
  • Is the damage to the wooden structure on a surface level or will boards and shingles need to be replaced?
  • Is the structure infected by moss and lichen or black algae? If so a treatment before cleaning must be done to rid the deck of these.
  • What is most cost effective to the customer and what procedure will last the longest?

By starting with a good survey it gives both the customer and the restoration expert the opportunity to take the measured steps required in bringing back the wooden structure to its original appearance. Different types of wood require different types of cleaning procedures and chemicals. The woods condition and its current appearance will give the restoration company, a starting point on what needs to be done next.

Chemicals Used in Wood Restoration

Each chemical in the process of wood restoration carries a function. The mixtures for these chemicals can vary widely due to:

  • The level of cleaning needed.
  • The wood type being cleaned.
  • Whether the wooden structure will be stained or has stain currently on it.

Below is a sample table with some common chemicals used in wood restoration. This is not meant as an all inclusive list but as a starting point for what is commonly used in the renovation of wood.

Chemical

Function

Oxygen Bleach

Draws dirt to it gently, used as a green material.

Citric Acid

Brightens and restores natural hues.

Sodium Hypochlorite

Removes top layers of grime, kills moss and lichen.

Trisodium Phosphate

Removes paint stains and rust. Helps kill moss and lichen.

Oxalic Acid

Brightens and remove rust stains. Sets an even tone to wood.

WARNING! The use of these chemicals and their mixtures should only be done by an experienced wood restoration expert. Wrongly mixing chemicals such as Oxalic acid with Oxygen bleach can cause VERY serious injuries. These 2 chemicals cause a reaction that causes noxious gases and when mixed with water can even cause explosions.

The Process

There are steps to properly restoring wood. Certain chemicals are used for each step in the process; wood restoration is also done in a standard order:

1. Cleaning

Depending on what the restoration expert believes is appropriate for cleaning; the deck, gazebo or roof is usually sprayed with a mixture of oxygen bleach or a trisodium/sodium hypochlorite cocktail. This is done to lessen the amount of time it will take to power wash the structure. Power washing by the expert is done with the upmost care to limit the furring of the wood, usually at a PSI of 1000 or lower for wood structures.

2. Brightening:

The process of brightening can be accomplished with either oxalic acid or citric acid or a brightening agent of the restoration experts choosing. This process also helps to neutralize the effects of having used heavy cleaners on wood. It also helps to bring out the woods natural color and grain patterns.

3. Staining, Sealing & Weatherproof

After brightening and neutralizing your deck or roof, a sealer, stain or weatherproofing product should be applied to extend the life of the cleaning and protect the wooden structure from UV rays and rain. The product can vary by the customers or restoration experts’ opinion on the best method for the type of structure. For instance, a cedar roof would receive an oiling while a deck would receive a stain with rain and UV inhibitors.

Appearance and the customers concerns also determine the right product to use. There are many products out there today that contain algae resistant chemicals and coloring to add both protection and improved appearance to the cleaned, brightened and stained wooden deck, roof, gazebo or furniture.

Conclusion

Seattle is home to over 150 days of rain a year. Moss, Lichen and mold are a problem we are constantly battling to control. Decks are an inviting environment for the growth of moss and lichen, and are also victims to the effects of weathering. Proper care and maintenance of wooden structures should be done on a yearly basis. Choosing the right chemicals, tools and procedures can either enhance or ruin a deck.
