Fundamentals Of Roof Cleaning

If you store or park your RV and truck beneath trees that leave sap or leaves, or should you go to places that are moist and warm with a higher possibility of creating a mold, then you know just how fast your roof will get filthy.

With roof cleaning, you must check your roof for cracks, rips, tears, as well as caulking separations. That can help prevent expensive repairs and damaging leaks. Before you check the roof, ensure that the roof is strong enough to support somebody walking or standing on top.

But if not, you will have to clean, check and fix your roof with the ladder’s safety

RV Roof Types

Fundamentals of Roof Cleaning

There are numerous types of RV roofs. The most popular are fiberglass roofs, rubber roofs, and PVC roofs.

Rubber membrane roofs are constructed from a thin weather-proof rubber membrane that’s extended throughout the wooden substrate (like PVC roofs that have Polyvinyl Chloride).

Roofs made from fiberglass are molded. It is recommended to have them polished, so any stuff that rests on it will slide off. The majority of fifth-wheels and travel trailers have PVC or rubber roofs.

Rubber roofs are extremely durable and firm, but certain chemicals can damage them. Acidic (frequently citrus-based) cleanser, abrasive cleaners, as well as any item that utilizes a petroleum distillate has the ability to destruct the roof surface.

And to cleanse rubber roofs, simply follow the comprehensive list below:

Cleaning A Rubber RV Roof

  • Initially, in cleaning the roof, you need to have a clean sweep of the debris, focusing on the spots around the fixtures. Also, this is a good time to check the caulking if there are any cracks around.
  • Rinsing the roof using a hose is always more convenient than rinsing it with a pail of water. In order to stop the streaks from flowing down your RV, it would help to rinse the front and sides of the RV right before you head up to its roof and proceed with all through the washing procedure.
  • Then, spray cleaner (rubber roof) straight over the roof, and then scrub using a medium-bristled brush or long sponge mop. Tackle a tiny part at a time (three feet by three feet) and apply a clockwise or counter-clockwise motion. While moving through the roof, seek tears and rips in the material.
  • Rinse, but take heed not to fall off or slipping the damp roof! Also, watch behind, so that you do not trip over an air conditioner or vent. As stated earlier, it is safer to use a ladder and stand on the side while using a brush with a longer handle to perform the cleaning procedure.
  • Treating a rubber roof’s surface with a first-class protectant makes washing much easier and offer another protection layer against the harmful elements.

Fiberglass and PVC roofs may be cleansed just like rubber roofs are cleaned, except you must utilize a splash of oil soap rather than rubber roof cleanser.

If the PVC or fiberglass roof acquires a sticky stain, then check out a few of the excellent cleaning products and brands at Amazon because they’ll be amazingly helpful in taking them off.

On the other hand, there’s one particular note to remember with fiberglass roofs right after the cleaning procedure; they’ll require a protectant, such that they do not oxidize or rust out.

Without the application of these protective products, then fiberglass roofs can lose their sparkle, feel uneven to your touch as well as slough off the powder.

Go through the tips below right after the cleaning of the RV roof, and you will be certain to keep the roof shiny and nice for a very long time.

Cleaning Fiberglass RV Roofs

  • Surface oxidation should be taken away before the protectant is used towards the fiberglass roofing. And if there’s slight oxidation, then a simple one-step method is to apply a restorer or wax or cleaner. These waxes have a slight to average abrasive.
  • Applying on 3 x 3-foot places, brush with these items in a clockwise or counter-clockwise motion. Allow it to dry and buff it away to shine, and the roof of your RV is cleaned.
  • If your roof is more oxidized, then make use of a mild abrasive that contains a polish. If ever the polish cannot make the material smooth, dab a compound for rubbing over the buffer pad. This compound is extremely harsh, therefore, tread softly with your buffer, and include rubbing compound just as required. You can also use an electric pressure washer to make the process of rinsing much easier for you to do.
  • Unless you’re aware of what you’re doing, it is the best option to have the cleansing done with a rubbing or polishing compounds to the experts. Perhaps, when the roof looks very shiny after first cleaning or a protectant’s treatment, in reality, it is only for the short-term.
  • To stop further oxidation, it is highly recommended to have the material painted with excellent epoxy paint, such as Imron, to ensure that the surface stays attractive and is constantly safeguarded from the elements. After taking away the oxidation and cleaning the roof, it would then require a protectant.
  • A few RV manufacturers suggest utilizing "Aerospace Protectant" to shield the fiberglass against ultraviolet rays, to remove dark streaks from developing over the walls as well as to provide the roof with a sparkly luster. Use a protectant instead of waxing.
  • Another choice is to apply a layer of paste or wax on your roof. Take caution when walking on the waxed roof because it can be very dangerous and slippery.
