Roof Cleaning Can Help You Sell That House

While the housing market is slowly rebounding from one of the worst slumps in decades, many homeowners that are trying to sell are brainstorming creative ways to differentiate their homes from the rest. Some have the interior painted, some work on the landscaping, while others will actually go so far as to throw in gifts like electronics and furniture. But very rarely does it occur to these folks that their filthy, algae-covered roof is probably keeping the buyers away!

Imagine a potential buyer pulling into the driveway of an otherwise beautiful home, but the roof is covered in some kind of mystery black stuff. Theyre going to think to themselves that the roof is sick and may even need replacing . Theyll be adding up the cost of a new roof before theyve even stepped foot inside the house! Hows that for lousy curb appeal!!! Sellers cant afford to be this careless with how the exterior of their home looks. That bad first impression that the potential buyer has will often trump any upgrades or features that are inside the house. Roof stains and/or moss could also catch the attention of a home inspector who might decide to make negative comments about it to his clients, who in turn offer less than they would otherwise.

This loosens the shingles granules causing your roof to deteriorate faster and lessens its ability to reflect heat. This ultimately leads to higher utility bills and a much shorter shingle life.

What Kind Of Damage Happens When You Pressure Wash A Roof

Should You Have a Roof Cleaning Done This Summer?

Using a pressure washer to clean a roof does two things:

  • It lifts the shingle tabs and breaks their seal.
  • It removes the protective surface granules on the shingle.

Asphalt shingle roofing systems are usually installed as a restrained tab or a self- sealing system. That means that each shingle has a sealant strip on it so that when they are installed correctly, each row of shingles will adhere or seal themselves to the row above and below them.

Picture is from

Asphalt roofing systems are designed to withstand a certain amount of wind load. It is this self-sealing shingle system that makes you roof wind resistant and keeps your shingles from blowing off the roof during most storms.

When a pressure washer is used to clean a roof, regardless of how careful the wand wielding cleaner is, there is a high probability that some shingles are going to get lifted and this seal will be broken. This leaves your shingles flapping in the wind during the next storm.

You will also lose a lot of the surface granules from your shingles. These granules play a role in protecting the shingle and helping to reflect the suns rays so your attic stays cool. The older the roof, the more granules you will lose in the washing process.

While you cant always do much about airborne dust and other debris created by nearby production facilities, construction zones, and roadways, you can reduce the dust and dirt around your property with regular power washing services.

Things You Should Know About Roof Cleaning

Roof cleaning is a hugely important part of home maintenance and may be the most important part of roof maintenance. Keeping your roof clean prevents decay, which could lead to expensive repairs or even a complete replacement of your roofing. Roof cleaning will extend the lifespan of your roofing and help the roof stay more functional for a longer period of time.

Roof cleaning contractors are available across the nation, and each of them have their own preferred methods and tools. So how do you decide on the right way to clean your roof?

Here are five things about roof cleaning that you should know before you hire a contractor or start on the process yourself:

Having Said That Let Us Now Look At The Question Of Pressure Washing

High powered pressure washers can cause extensive damage to RVs: cut tires, broken seals, paint damage, gel coat delamination, removal of decals the list is endless. Pressure washers can even force water into your rig. So please, NO HIGH-POWERED pressure washers! It is recommended that you do not use anything over 1300 PSI. Why? A 2500 PSI direct blast can break mortar and concrete: just imagine what it could do to your traveling home! If you do use a low-pressure power washer, set your nozzle to a lower setting and keep the nozzle at an angle and at least 15 inches from your rig.

The roof can be the dirtiest part of your RV and the area where you can be most tempted to blast away with that pressure washer. Dont! All the seams and caulk you could damage may result in a leaky roof. Perhaps that is why so many RV owners are turning to FlexArmor roofs. Our roofs are seamless and guaranteed not to leak. Maintenance is simplified without continued caulking and cleanup is easy with mild soap and water.

More Considerations To Keep In Mind

  • You only need to treat your roof to a power washing once every year or two. More than that and you may wind up subjecting it to more wear and tear than its built to withstand in a short amount of time.
  • That said, the inverse is true, as well. The roof of your home does need to be cleaned every now and then. Algae can ruin the appearance of your roof and mold can cause long-term damage, creating leaks. Your insurer probably requires you to keep your roof clean in order for your policy to remain valid.
  • If you dont have power washing training yourself, its a good idea to consider professional help on this one. The job is both delicate and dangerous, which is always a tricky combination if youre not completely comfortable with the task at hand.
  • Pressure washing and soft washing arent exactly the same thing. Pressure washing allows the water to come out at full force and is preferred for cleaning concrete, brick and industrial buildings. For most residential roofs, soft washing, which uses a special nozzle to limit the PSI of the sprayer, will be more than strong enough for the job.

We recommend enlisting a pro to handle the job. But, if you are going to try to tackle the job yourself. Remember: safety, safety, safety. Gloves, goggles, slip-resistant shoes, and dont forget the sunscreen.

Why You Should Not Pressure Wash Your Roof

Pressure washers produce highly-pressurized jets of water that can be used to blast sediment off surfaces. This cleaning method works really well when the surface being washed can stand up to that level of water pressure.

But while asphalt shingles are made to handle heavy rainfall, raindrops are not quite the same as a concentrated beam of water from a pressure washer. Simply put, unless you have it on a low setting, cleaning your roof with a pressure washer would likely do much more harm than good.

The water pressure wont damage just the shingles, either. Theres a good chance the jet of your pressure washer could work through the adhesive bond holding your shingles together, or seep into and damage your roofs fabric underlayment. Plus, pressure washers tend to blast sediment into the air, so its likely any dirt you do scrape off your shingles is bound to fall back down onto another section of your roof.

On top of all that, most pressure washers are simply not made for roof work. You could seriously injure yourself trying to lug your pressure washer up a ladder. And once its up there, theres no guarantee the weight of the machine wont damage your shingles.

So Can Pressure Washing A Roof Cause Damage

Why Roof Cleaning is Important For Homes and Why You ...

Pressure washing a roof can cause damage. Pressure washing will get your roof clean. It will look great when it is finished. The long-term damage is not worth it. Pressure washing causes a lot of damage. There are alternatives that work better and dont cause damage.
