Best RV Roof Coating and Sealants

RV roof coating and sealants are among the most essential and crucial products for your recreational vehicle’s maintenance, care, and lifespan. An RV roof coating seals, weatherproof, and waterproofs the roofs of RVs, campers, trailer homes, and vehicles.

Long-time RV owners lay testament that a well-cared, well maintained, and dependable roof eliminates three-quarters of the hardships and costs associated with RVs’ durability.

RV roofs are usually made out of rubber, aluminum, or fiberglass. Rubber roofs are the most common, and they are what most RV roof coating products cater to specifically. Aluminum roofs are similar to rubber roofs in that they also require the same amount of care and attention, if not more. Fiberglass roofs are more resilient to weather, water, and cracks but cannot be left unattended year long.

Why do you need RV Coatings and Sealants?

RV roof coatings provide a layer of protection from the elements in nature, including dust, rain, winds, debris, leaves, twigs, snow, and harsh UV rays. An excellent, effective roof coating helps prevent cracks in the roof, prevents molds and leakages, and protects the base roof membrane against decay.

They are critical along with the linings of pipes, windows, and air conditioning, where most leakages and cracks originate. RV roof coatings are also used to fix tears and cracks as a sealant. Roof repair work is mostly never complete without roof coatings, which seal and coat the roof against nature’s damage.

A recreational home is not an affordable investment for most people. Operating and living expenses are also hefty if not optimally managed. It should be vital that we protect and care for the individual parts of our home-on-wheels like the roof and minimize the maintenance and the operating costs to provide the biggest bang-for-the-buck when camping in recreational vehicles.

Obviously, for maintenance purposes, RV roof coatings are crucial for the ‘roof over our heads.’ Leakages, cracks, and moisture in the roof membrane can start as a slight discomfort but quickly make it almost impossible to live inside an RV. Moreover, energy costs often take the most significant chunk of the overall running expenses when living inside an RV.

Again, leakages and cracks in the roof or along the seams of protruding pipes and windows let the air conditioning escape from the insides of an RV, which drives up energy costs.

RV roof coatings (EPDM rubber or silicon) work as a weatherproofing, waterproofing sealant against potential cracks, tears, decay, and motorizing of the roof of an RV. They help make the roof durable and protected against degradation; they also help seal the air-conditioning to prevent leakages and keep the energy consumption low.

In addition to this, urethane and silicone types RV roof coatings offer high reflectivity, protecting against harsh UV rays and keeping the RV roof from heating up in sunlight, which again pushes down energy costs. Acrylic-type roof coatings are less expensive than silicone and urethane, but their best do provide minimal reflectivity.

Be sure to clean your roof first using a good RV Wash product.
