If you own your RV long enough, it’s almost certain that you are eventually going to have to make repairs to the roof. Regular inspections can help lessen the frequency and severity of repairs, but there is no accounting for accidental damage. The sooner defects and damage are addressed, the easier and less expensive they are to fix. The final step in repairing RV roof damage is to coat the area with one of the many available liquid roof repair coatings.
The Advantages of Liquid Roof Repair Coatings
EPDM rubber has always been a favorite RV roofing material for a number of reasons. A rubber roofing material is better able to withstand the stress of constant movement that RVs are subjected to. Also, EPDM rubber roofs are less susceptible to extremes in temperature thus helping to insulate your coach and keeping you warmer in winter and cooler in summer. In the days before the development of liquid EPDM rubber, this type of coating could only be applied in sheets, which worked well until it became necessary to repair or replace part of the surface. Covering a repair area with a sheet of rubber was difficult at best because one was always left with the problem of what to do with the seam. Products like caulks and putties came out that attempted to address the problem, but nothing really seemed to do the trick. That all changed when liquid roof repair coatings made from EPDM rubber came on the scene. Now, because a liquid could quickly and easily conform to any shape, even a raised surface, it was finally possible to get a long-lasting seal on any repair.
Things to Consider When Using Liquid Roof Repair Coatings
All liquid roof repair coatings are not created equal, so what do they have in common? Liquid EPDM roof coatings will only adhere to surfaces that are clean, dry and free of any film or dust. Getting an area repaired and in that kind of condition takes time. The good news is liquid roof repair coatings are easy to apply. It’s pretty much the same as any other type of painting. That’s where the similarities between brands end. Because properly repairing an RV roof is labor and time intensive, you don’t want to spend any more time than is necessary getting the job done. Some liquid roof repair coatings require you to apply two coats in order to get a lasting finish. That doesn’t make any sense. First of all, if they can’t do the job in one coat, what assurance do you have that it will be done properly in two coats? Second, by requiring a second coat, they’ve added hours of drying time to the job. There is a product out there that provides a long-lasting finish in just one coat, saving you a lot of money and hours of time. If you went to the hardware store to buy interior paint for your house, which one would you buy; the one that takes two coats to cover, or the one that covers well in just one coat?
Tips for Using Liquid Roof Repair Coatings
If you are doing the repairs on the roof yourself, take some time while you’re up there to thoroughly inspect the whole roof, not just the obvious areas. Check around the base of the vents, antennae, air conditioning unit and around the roof’s edges. If you’ve taken the time to go up on the roof, it just makes good sense to be certain that you’ve accounted for everything.
