Professional Roof Cleaning Service For Morrisville Pennsylvania, Zip 19067
Let’s talk about roof cleaning. Cleaning a roof in Morrisville Pennsylvania is not a “pressure washing” job! Please do not let anyone pressure wash your roof or use any device which is hooked up to a pressure washer. Even at low pressures a roof can be degraded and can shave years off the life of a roof. You may ask how we know this but the proof is in your gutter right now. Look into the gutter of any house. You will always find a fair amount of roofing granules that wash off even with wind and rain. If you can understand that roofing granules can dislodge from wind and rain alone than consider what using a pressure washer can do. There are companies that use this pressure washing method and you will here them use the buzz word over and over again “low pressure, low pressure”. I’m not sure about you or anyone else considers low pressure but to me, low pressure is what comes out of a garden spigot. Any pressures higher than that or especially if you’re hooked up to a gas powered pressure washer, it would not be good for the shingle. Please consider this when choosing a roof cleaner.
There are 2 schools of thought when it comes to roof cleaning: The first school is what I described in the introduction. There are companies like Roof Shampoo that use a device on the roof that looks like a floor buffer. They have nice videos that show all of the roof staining, vegetation and debris flowing off of the roof. What you never see in those videos is that the machine they are using is hooked up to a gas powered machine. This machine uses the force of the water to remove algae and vegetation from the roofing shingles. They will most likely clean out your gutters when they are done (disguised as a free courtesy service). The truth is most likely they don’t want you to see all of the roofing granules in your gutter that grind off of the shingle during the process of their “low pressure” cleaning. They will offer you a warranty somewhere in the neighborhood of 2 years. This process that I describe is not suggested anywhere in any roof manufacturers suggested roof cleaning methods. This method is someone’s invention, their own idea of how roofs should be cleaned.
Roof Shampoo is a national franchise roof cleaning company. Anyone can buy into their franchising. Even you can be a roof cleaner under Roof Shampoo if your market is available. Now I’m not here trying to bash them. They hold a valuable place in the market. Many times people will call us who are selling their home. Their realtor may suggest removing the moss and algae from the roof. These people may even call us in a panic who are trying to close on the sale or they may say, “OMG, the realtor is coming tomorrow to take pictures and my roof looks horrible. Help!”
This is where Roof Shampoo helps the Morrisville Pa. market. Roof Shampoo will come in and use their pressure washing device to blast all of the debris from the roof and the roof will be instantly moss and algae free. Since the home is for sale, who cares if any long term damage was created as a result of this pressure washing method. Regardless the method, of they remove the moss it’s a success. These are the times where Roof Shampoo saves the day. Unfortunately for the new owners it is likely that many of the roofing granules where washed off in the process and they are now the new owners of these roofing shingle.
Now for 2nd school of thought: The chemical cleaning process. This is the process Thompson Roof Cleaning uses. We almost hate to use the word “chemical” because it brings such a negative connotation. But let me start with the hard truth: Roof shingle manufacturers, even the most popular ones like Timberline, all suggest using a bleach based product on the shingle. They make the shingle. They’ve done the tests. They know what is safe and compatible with the shingle. Let’s explore why we feel this is the better option for cleaning the roof.
The chemical of bleach is called “sodium hypochlorite”. This is the same product used to keep swimming pools and gym saunas free of algae and viruses, and unless you have well water there is sodium hypochlorite in your tap water. Local municipalities are the largest purchasers of sodium hypochlorite. They add it to our tap water to keep it sterile. It is safe, effective and truly biodegradable. You can Google yourself how bleach is made, but it is essentially made from sodium chloride (common table salt).
Now, we get it. Nobody likes the thought of chemicals on the roof. But the roof is expensive. We want to clean it the way the manufacturers suggest. Just like a car: a car uses oil. Would you not use the oil suggested by the maker of the car? Of course you would. A car is expensive. I wouldn’t use any other product. This is why we use sodium hypochlorite (bleach) on a roof. And though bleach is not necessarily a plant friendly product there are ways to protect the surrounding landscape to prevent burning any bushes of plants. Forget about anybodies idea of using a plant friendly product to kill moss. Moss is in the plant family. We need to use something that has the ability to kill plants. If it can’t kill the plants on the ground it will not work for the roof. Landscapes can be covered and kept thoroughly watered to prevent any damage. Any roof cleaning fluid that comes down the gutter system can be re-captured and taken off site. We do not let the roof mixture to run into the flower beds.
The benefits of using the chemical method is we can be sure once it is applied it will kill the moss at the root level. The pressure washing methods basically crops the moss at the top leaving the root intact. Moss is like a weed. If you don’t get it at the root it will return rather quickly. This is why chemical process companies will offer 3-5 year warranties where as the pressure washing companies offer 1-3 year warranties.
When we started cleaning roofs back in the late 1990’s we weighed all of the options for cleaning roofs. Using the manufactures method of using a bleach detergent is by-far the safest and most effective way to created absolute sterilization for all mold, moss and algae. We do not approach this as a satin. we approach this as a “pest”. Our goal for every job is to solve an infection. a clean roof is merely a by-product of solving the infection.
Slate Roof Cleaning Morrisville Pennsylvania
Slate roofs are not cleaned much differently than regular asphalt shingle roofs. Slate roof detergent requires a bit more surfactant to create cling to the slate. We do not walk on slate roofs to clean them of algae and moss. Most can be sprayed from the gutter line. Our ladders have stabilizer bars so the ladder never toughed the gutter. Slate roof cleaning in Morrisville Pa. is a specialty trade service and should not be perform by the unskilled homeowner.
Cedar Roof Cleaning Morrisville Pennsylvania
Cedar roof shakes are a natural unique surface. We use a milder detergent than slate and asphalt. Bleach is technically not a compatible product for a shingle. Therefore it is left on for a very short dwell period than neutralized. Than it is rinsed. We keep the solution on just long enough to kill the moss and dissolve any black mold or algae. Cleaning a cedar shake roof 3 or 4 times over the life of the shake using this method will not cause any measurable damage to the cedar shake. It is not recommended to use this method many times more than needed over the course of the life of the cedar roof.
