Roof Cleaning

Softwashing is a method of cleaning surfaces, such as roofs, siding, and other exterior surfaces, using low-pressure water and specialized cleaning solutions instead of high-pressure water. The cleaning solution is applied to the surface, left to sit for a certain amount of time, and then rinsed off with low-pressure water. Softwashing is often used to remove dirt, grime, mold, algae, and other organic growths from exterior surfaces without causing damage to the surface itself. It is a safe and effective alternative to pressure washing, which can cause damage to some surfaces if used improperly. Softwashing is commonly used in the cleaning of residential and commercial buildings, as well as in the cleaning of outdoor surfaces such as concrete, pavers, and decks.

Yes, bleach is a safe household chemical. It has been in regular consumer use for over 100 years and is biodegradable. Bleach is recommended by the CDC and the WHO for sanitizing surfaces, and in 2020 was named as the #1 preferred solution for disinfecting surfaces of the Corona virus (Covid19). Bleach is widely available and is cost effective. Bleach occurs naturally in the environment, and has known variables.

The chemical name for bleach is Sodium Hypochlorite, which is commonly called liquid chlorine and pool shock. Bleach is on the US DOT listings for hazardous materials as well as on the list for hazardous substances. Because Sodium Hypochlorite is on the hazardous substances list, a commercial drivers license is required along with a hazardous materials endorsement in order to transport more than 119 gallons.

We are seeing cost increases in supplies, fuel, labor and taxes. The cost to clean most types of roofs can fluctuate depending on the type of surface and the degree to which maintenance has been deferred. Most types of roofs will cost between $0.40 and $0.55 per square foot to clean, restore and qualify to receive our 3-year warranty.

Roofs are expensive to repair and replace, so keeping a clean and well maintained roof is very important, and a good investment. When a roof is not maintained properly in the Pacific Northwest, debris such as pine needles, leaves and pollen will collect in valleys and behind vents and chimneys. The organic buildup will decompose and create a fertile bed for algae (gloeocapsa magma), moss and lichen, all which have aggressive root structures that work to break apart the protective layers of your roof. This, in combination with excessive moisture, in time will allow water to infiltrate the roof, creating soft spots, dry rot in calls and rafters and eventually failure of the structure. It is critical to maintain your roof, keeping it clear of all growing organic species.

Determining the best method to clean a roof depends on 3 main factors: (1) the type of roof material, (2) the current condition of the roof, and (3) the safety of the working crew. When considering these 3 factors, in almost every case, the best method for cleaning roof is to apply a soft washing treatment of sodium hypochlorite and various biodegradable enzymes and surfactants to safely emulsify the organic matter. Over time (typically 30 to 90 days) the roof will return to its original color and condition. In some cases, it may be necessary to brush and/or blow bulk organic debris from valleys and behind vents. A thorough cleaning of the gutter and downspout system should always be performed with cleaning the roof.

A soft clean, or soft wash cleaning for a roof that involves applying a low-pressure (about 70PSI) mixture of sodium hypochlorite, biodegradable enzymes, surfactants and water to the entire roof surface is typically between $0.40 and $0.55 per square foot in 2022. This includes a 3-year warranty.

The dark streaks you see on your roof is a bacteria called gloeocapsa magma. Gloeocapsa Magma is a species of cyanobacteria. Cyanobacteria are an ancient line of photosynthesizing bacteria that photolyze water-generating oxygen gas. You must treat these types of bacteria and algae with the appropriate combination of chemicals to ensure a 100% kill ratio. This cleaning method more closely resembles a pest control application, rather than pressure washing.

Sodium Hypochlorite is a yellow fluid that is used for sanitation, cleaning and bleaching. At DAPrDAN, we use sodium hypochlorite that comes in a 12.5% strength. OSHA 1910 states that the SH must be labeled for building exterior cleaning. Sodium Hypochlorite is commonly packaged in a yellow 2.5-gallon jerry jug, 5-gallon tote, 15-gallon carboy container, 35-gallon barrel, 55-gallon barrel, and 250-gallon totes. The DOT identification number for bleach is 1791 and for transportation requires labeling, but not always placarding.

Aesthetics: Many people choose to clean their roofs regularly in order to prevent ugly collections of leaves and needles, as well as streaks from green moss, algae and bacteria. Insurance: Recently, many insurance underwriters have rejected homeowners insurance policy renewals because there is moss growing on the roof. Moss is the number one reason for the premature replacement of roofs. Energy efficiency: The dark color of algae when covering a large part of the roof can cause the roof to absorb a significant amount of heat from sunlight, even up to 30%. Health: The accumulation of mold and fungus on roofs can spread through the air, grow on the front stoop and tracked into the home. This can be drawn into the air duct system and spread throughout the home. Design function: Regular roof cleaning will maintain the proper function of the roof design to shield the house from adverse weather conditions.

Mold, mildew, fungus and algae are all in the top 10 allergy irritants list. Mold and fungus are known culprits in Sick Building Syndrome. Moldy areas are one of the top environments looked for in a Legionnaires Disease outbreak. Growing cultures of bacteria and fungal strains may be dangerous to your health. Fungus on the roof spreads to the front stoop, which is stepped on and tracked into the home. From there, it resides in carpets and is pulled into the ducting system and spread throughout the house. Musty smelling homes are often due to moldy roofs.

Pressure washing only strips away the top of the algae bloom, or moss infected areas. Roots of the infestation are still within the surface you are cleaning. Power washing blasts the pores deeper into the surface. For example, when you mow your grass on a regular basis, it grows back thicker and healthier, and when you prune your hedges on a regular basis, they grow back thicker and healthier. Likewise, when you power wash your algae on a regular basis, it grows back thicker and healthier. It’s a lot like giving it a haircut, and then spreading it around. Soft washing is the best alternative to pressure washing. Soft washing treats the infestation at the root, and does not cause any damage from pressure. The cleaning solution offered by soft washing is a more sustainable cleaning model above and beyond aesthetics.

Before hiring a contractor to clean your roof, it’s important to ask some important questions to ensure that you choose a reputable and experienced professional. Here are some examples:

1) What experience do you have with cleaning the specific type of roof that I have?

2) What cleaning methods do you typically use, and are they safe for my roofing material?

3) Do you have liability insurance and workers’ compensation insurance?

4) Can you provide references from previous customers, and can I see before and after photos of previous jobs?

5) How long will the cleaning process take, and what is the estimated cost?

6) Will you need to use any chemicals or cleaning solutions, and are they safe for my family and pets?

7) What precautions will you take to protect my landscaping and other outdoor features during the cleaning process?

8) Do you guarantee your work, and if so, what is your policy for addressing any issues or concerns that arise after the job is complete?

9) Will you provide a written estimate or contract before starting the job?

10) What steps will you take to prevent damage to my roof, gutters, and other features during the cleaning process?

Asking these questions can help you make an informed decision when choosing a contractor to clean your roof, and can help ensure that the job is done safely, efficiently, and to your satisfaction.

Gutter Cleaning

Gutter cleaning is important for several reasons, including:

Preventing water damage: Gutters are designed to channel water away from your home’s foundation and prevent water damage. When gutters are clogged, water can overflow and cause damage to your roof, walls, and foundation.

Protecting your landscaping: When water overflows from clogged gutters, it can damage your landscaping and cause erosion.

Preventing pests: Clogged gutters can provide an ideal breeding ground for pests like mosquitoes, termites, and rodents.

Maintaining the integrity of your roof: When gutters are clogged, water can accumulate on your roof, causing damage and reducing its lifespan.

Avoiding costly repairs: Regular gutter cleaning can help you avoid costly repairs caused by water damage.

Overall, gutter cleaning is an essential part of home maintenance that can help you avoid costly repairs and protect your home from water damage and pests.

It is recommended to clean your gutters at least twice a year, typically in the spring and fall. However, the frequency of gutter cleaning may vary depending on several factors such as the number of trees around your home, the amount of rainfall in your area, and the type of gutters you have. If you notice that your gutters are overflowing or clogged with debris, you may need to clean them more frequently to prevent damage to your home’s foundation or roof. It’s also a good idea to inspect your gutters after any major storms or extreme weather conditions.

Not cleaning gutters can lead to a variety of risks and problems. Here are some of the main risks:

Water damage: Clogged gutters can prevent water from flowing properly and may cause water to overflow, leading to water damage to your property’s roof, walls, foundation, and basement. This can result in costly repairs and structural damage.

Pest infestations: Clogged gutters can become a breeding ground for pests, such as mosquitoes, rodents, and insects. These pests can cause health hazards and property damage.

Roof damage: If gutters are clogged, water can back up onto the roof and cause rotting, leaks, and damage to shingles and other roofing materials.

Ice dams: In colder climates, clogged gutters can cause ice dams to form on your roof, which can lead to water leaks and damage to your home’s insulation.

Fire hazard: Dry leaves, twigs, and debris that accumulate in clogged gutters can be a fire hazard, especially during dry and hot weather conditions.

In summary, neglecting to clean your gutters can result in serious damage to your home, leading to costly repairs and safety hazards. It’s important to clean your gutters regularly to prevent these risks.

Gutter cleaning can be done by homeowners, but it depends on the homeowner’s comfort level and the level of difficulty of the task. Here are some factors to consider:

Safety: Gutter cleaning can be dangerous, especially if you have a multi-story home or a steeply pitched roof. If you are not comfortable climbing a ladder or have limited mobility, it’s best to leave gutter cleaning to professionals.

Equipment: To clean gutters properly, you need the right tools, such as a sturdy ladder, gloves, a trowel or scoop, and a hose or pressure washer. If you don’t have the necessary equipment, it may be more cost-effective to hire a professional.

Time: Depending on the size of your home, cleaning gutters can take several hours. If you don’t have the time or energy to do it yourself, a professional can get the job done more quickly and efficiently.

Experience: If you have never cleaned gutters before, it can be challenging to know how to do it properly. A professional will have the experience and knowledge to do the job right.

In conclusion, while gutter cleaning can be done by homeowners, it’s important to consider the factors above and determine whether it’s best to hire a professional or do it yourself. If you have any doubts about your ability to safely and effectively clean your gutters, it’s always best to hire a professional.

The cost of professional gutter cleaning can vary depending on several factors such as the size of the home, the type of gutter system, the level of debris in the gutters, and the location.

On average, the cost of professional gutter cleaning can range from $250 to $500 or more. For a typical single-story home, the cost can be around $250 to $300. For larger or multi-story homes, the cost may be higher.

In some cases, additional services such as gutter repairs or installation of gutter guards may also be recommended, which can add to the overall cost of maintaining your gutter system.

It’s always best to get a quote from a professional gutter cleaning company to get an accurate estimate of the cost based on your specific needs and circumstances.

Here are some common problems that can occur with gutters:

Clogging: The most common problem with gutters is clogging caused by leaves, twigs, and other debris. This can cause water to overflow and damage your home’s exterior.

Sagging: Gutters can sag or pull away from the house due to the weight of debris or water. This can cause water to overflow and damage your home’s foundation.

Leaks: Over time, gutters can develop leaks due to rust, corrosion, or damage caused by fallen branches or animals.

Improper installation: If gutters are not installed correctly, they may not slope properly, which can cause water to pool and lead to clogging or overflow.

Inadequate drainage: If gutters are not properly connected to downspouts or if downspouts are clogged, water may not drain properly and can cause water damage to your home’s foundation and basement.

Ice dams: In colder climates, ice dams can form on gutters when snow melts and refreezes. This can cause water to back up and damage your roof and interior walls.

Wear and tear: Gutters can wear out over time due to exposure to the elements, and may need to be repaired or replaced.

It’s important to address these problems as soon as possible to prevent further damage to your home. Regular maintenance and inspections can help identify and prevent these issues.

There are a few signs that can indicate that your gutters need cleaning:

Water overflow: If you notice water overflowing from your gutters during rain, it is a sign that they are clogged with debris and need to be cleaned.

Sagging gutters: If your gutters appear to be sagging or pulling away from your home, it is a sign that they are carrying too much weight, which can be caused by debris buildup.

Plant growth: If you notice any plants growing in your gutters, it is a sign that they are not draining properly, which can be due to blockage.

Visual inspection: If you can safely access your gutters, you can inspect them visually for any debris buildup, such as leaves, twigs, or dirt.

It is recommended to clean your gutters at least twice a year, typically in the spring and fall. However, if you notice any of the signs above, you should clean them as soon as possible to prevent any damage to your home’s foundation, roof, or siding.

Here are some questions you can ask a contractor before hiring them to clean your gutters:

1) Have you cleaned gutters before? Are you licensed and insured?

2) What kind of equipment do you use to clean gutters? Will it be safe for my gutters?

3) How long do you think it’ll take to clean my gutters, and how much will it cost?

4) Will you be removing all debris from my gutters and downspouts?

5) I love my yard and garden, will you take care to protect my landscaping during the cleaning process?

6) Can you show me some before and after photos of previous gutter cleaning jobs? And do you have references from other customers you can share?

7) Do you offer any guarantees on your work, and what’s your policy for addressing any issues or concerns that may come up after the job is done?

8) I’m worried about any loose gutter spikes or brackets, will you be able to tighten those during the cleaning process?

9) Can you check my gutters for any repairs that may be needed, such as leaks, damage or rust?

10) Will you be flushing my downspouts to make sure they’re not clogged?

Asking these questions can help you choose the right contractor to clean your gutters safely and efficiently, ensuring your satisfaction with the job.

Siding Cleaning

Cleaning your house siding is a good idea for several reasons:

Improves Curb Appeal: Cleaning your house siding can significantly improve the overall appearance of your home. Dirt, grime, and other debris can accumulate on your siding over time, making it look dull and uninviting. A thorough cleaning can restore your siding’s original color and shine, making your home look fresh and new.

Prevents Damage: Dirt and debris can build up on your siding, causing damage over time. Mold, mildew, and algae can also grow on your siding, which can eat away at the material and cause rotting. Regular cleaning can prevent these issues, saving you money on repairs in the long run.

Protects Your Health: Mold, mildew, and other allergens can grow on your siding, which can be harmful to your health. Regular cleaning can prevent the growth of these allergens, keeping your family safe and healthy.

Increases Lifespan: Regular cleaning can extend the lifespan of your siding. Dirt and debris can cause premature aging of your siding, which can lead to the need for expensive replacements. By keeping your siding clean, you can ensure that it lasts as long as possible.

Overall, cleaning your house siding is a good idea because it can improve the appearance of your home, prevent damage, protect your health, and increase the lifespan of your siding.

It is possible to clean your house siding with just water, but it may not be as effective as using a cleaning solution. Water alone may not be able to remove tough stains or dirt buildup, especially if it has been present for a long time.

Using a cleaning solution can help break down dirt and grime and make it easier to remove. There are several types of cleaning solutions that can be used for house siding, including mild soap, vinegar, bleach and specialized cleaning products designed specifically for siding.

It’s also important to consider the type of siding you have before cleaning with any solution. For example, some types of siding, such as wood and vinyl, may require a specific type of cleaning solution to avoid damage. It’s always a good idea to read the manufacturer’s instructions or consult with a professional before cleaning your siding.

In summary, while it is possible to clean your house siding with just water, it may not be as effective as using a cleaning solution. Using a cleaning solution can help remove tough stains and dirt buildup, but it’s important to choose the right solution for your specific type of siding.

The frequency at which you should clean your house siding depends on several factors, including the climate in your area, the type of siding you have, and the amount of exposure your siding has to environmental elements such as wind, rain, and sunlight.

As a general rule of thumb, it is recommended to clean your house siding at least once a year. However, if you live in an area with high humidity, or if you have a lot of trees or other vegetation around your home, you may need to clean your siding more frequently.

Additionally, if you notice any signs of mold, mildew, or other types of damage on your siding, it’s important to clean it as soon as possible to prevent further damage.

Regularly inspecting your siding for signs of wear and tear, and addressing any issues promptly, can help extend the lifespan of your siding and keep it looking its best.

Overall, it’s best to consult with a professional or refer to the manufacturer’s instructions to determine the appropriate cleaning frequency for your specific type of siding.

Bleach is a preferred method for cleaning siding because it is effective at killing mold and mildew, which are common issues that can develop on exterior siding. Bleach contains sodium hypochlorite, which is a powerful disinfectant that can kill mold and mildew spores on contact.

Bleach is also effective at removing stains and discoloration from siding, such as those caused by algae or other types of buildup. It can break down dirt and grime, making it easier to remove during the cleaning process.

Another advantage of using bleach for siding cleaning is that it is relatively inexpensive and readily available. Bleach is a common household cleaning product that can be easily purchased at most grocery stores and hardware stores.

However, it’s important to note that bleach can be corrosive and can damage some types of siding if not used properly. It can also cause discoloration or damage to nearby plants or landscaping if not diluted properly or if oversprayed.

It’s recommended to follow the manufacturer’s instructions or consult with a professional before using bleach to clean your siding, especially if you have a delicate or non-traditional type of siding material.

Pressure washing can potentially damage your siding if not done correctly. Here are some ways pressure washing can damage your siding:

Water Pressure: If the pressure washer is set to a high pressure, it can strip away the top layer of your siding or even punch holes in it. It can also cause water to be forced behind the siding, leading to mold, mildew, and other water damage.

Incorrect Angle: If the pressure washer is angled towards the siding at a steep angle, it can cause the siding to loosen or break. It’s important to use the pressure washer at a flat or gentle angle to avoid this problem.

Improper Technique: If the pressure washer is used incorrectly, it can cause streaks, lines, or other marks on your siding. It’s important to use the pressure washer evenly and with the proper technique to avoid this issue.

Fragile Siding: Some types of siding, such as older or more fragile materials, may not be able to withstand the force of pressure washing. In these cases, a gentler cleaning method may be necessary.

It’s generally recommended to clean your house siding before painting. This is because cleaning your siding before painting can help ensure that the paint adheres properly and lasts longer.

Cleaning your siding before painting can help remove any dirt, grime, or other debris that can interfere with the paint’s adhesion. This can help the paint adhere more evenly and prevent it from peeling or flaking off over time.

In addition, cleaning your siding before painting can help identify any areas that may require additional prep work, such as repairs or priming. This can help ensure that the final result is smooth and even.

However, it’s important to wait until your siding is completely dry before painting. If you paint your siding while it’s still wet, the moisture can interfere with the paint’s adhesion and cause it to peel or flake off.

Overall, it’s best to consult with a professional or refer to the manufacturer’s instructions to determine the appropriate steps to take when cleaning and painting your specific type of siding.

When hiring a contractor to clean your siding, there are several questions you may want to ask to ensure that you choose a reputable and experienced professional. Here are some examples:

1) What experience do you have with cleaning the specific type of siding that I have?

2) What cleaning methods do you typically use, and are they safe for my siding material?

3) Do you have liability insurance and workers’ compensation insurance?

4) Can you provide references from previous customers, and can I see before and after photos of previous jobs?

5) How long will the cleaning process take, and what is the estimated cost?

6) Will you need to use any chemicals or cleaning solutions, and are they safe for my family and pets?

7) What precautions will you take to protect my landscaping and other outdoor features during the cleaning process?

8) Do you guarantee your work, and if so, what is your policy for addressing any issues or concerns that arise after the job is complete?

Asking these questions can help you make an informed decision when choosing a contractor to clean your siding, and can help ensure that the job is done safely, efficiently, and to your satisfaction.

Window Cleaning

Professional window cleaning companies like DAPrDAN use a variety of methods, including traditional squeegee and cloth, water-fed pole systems, and pressure washing. The method used will depend on the type of windows, the location of your home, and your specific needs.
