Cleaning Supplies Checklist
For effective RV roof cleaning and sealing, you’ll need the right cleaning agents.
- RV-Specific Roof Cleaner: Brands like Dicor, Thetford, or Camco offer cleaners formulated for different roof types (EPDM, TPO, fiberglass, aluminum). Never use petroleum-based products, abrasive cleaners, or citrus-based cleaners on rubber roofs.
- Soft-Bristle Brush: A long-handled brush or a car wash brush is ideal. Avoid stiff brushes that can scratch or damage the roof.
- Bucket(s): For mixing cleaner and rinsing.
- Garden Hose with Spray Nozzle: For thorough rinsing.
- Clean Rags or Microfiber Towels: For detail work and drying.
Sealing Supplies Checklist
Once clean, your roof needs protection. The type of sealant depends on your roof material.
- RV Roof Sealant/Coating:
- For EPDM/TPO Roofs: Look for acrylic or elastomeric coatings specifically designed for these rubber membranes. Dicor, Liquid Rubber, and ProFlex are popular choices.
- For Fiberglass/Aluminum Roofs: May use specialized coatings or a high-quality RV paint designed for roofs.
- Self-Leveling Lap Sealant: Essential for sealing around vents, skylights, and other roof penetrations. Dicor Self-Leveling Lap Sealant is a widely used product.
- Non-Sag Lap Sealant: For vertical or sloped areas (e.g., roof edges, front/rear caps) where self-leveling sealant would run.
- Caulking Gun: For applying lap sealants.
- Putty Knife or Plastic Scraper: For carefully removing old, cracked sealant.
- Mineral Spirits or Acetone: For cleaning old sealant residue (use sparingly and check compatibility with your roof type).
- Painter’s Tape: To create clean lines when applying coatings.
- Paint Rollers and Brushes: For applying liquid roof coatings.
Step-by-Step: Your RV Roof Cleaning and Sealing Guide
Ready to get started? Follow these steps for a thorough and effective RV roof cleaning and sealing process. Remember to work on a cool, overcast day if possible, to prevent cleaners from drying too quickly.
Phase 1: The Deep Clean
A clean surface is crucial for any sealant to adhere properly. This is where your how to RV roof cleaning and sealing journey begins.
- Inspect the Roof Thoroughly: Before you even get wet, climb up and do a visual inspection. Look for any existing damage, tears, cracks in sealant, or areas of heavy grime. Note any areas that need extra attention.
- Clear Off Loose Debris: Use a broom or leaf blower to remove leaves, twigs, and loose dirt. This prevents mud from forming when you add water.
- Pre-Rinse the Entire Roof: Wet the entire roof surface with your garden hose. This loosens dirt and helps the cleaner spread evenly. Rinse down the sides of your RV as well, to prevent cleaner residue from drying on the sidewalls.
- Apply RV Roof Cleaner: Following the product instructions, apply your RV-specific roof cleaner. Work in small sections, usually 5-10 feet at a time, to prevent the cleaner from drying.
- Scrub Gently but Firmly: Use your soft-bristle brush to scrub the roof surface. Pay special attention to stubborn stains, mold, or mildew. For rubber roofs, scrub in a circular motion to lift dirt without damaging the membrane.
- Rinse Thoroughly: Rinse each section immediately after scrubbing, before the cleaner dries. Ensure all cleaner residue is washed away. Work from front to back or back to front, making sure dirty water flows off the roof and doesn’t pool. Rinse the sides of your RV again to wash off any runoff.
- Inspect and Repeat if Necessary: Once the entire roof is clean and rinsed, let it dry completely. Then, perform another visual inspection. If there are still dirty spots, repeat the cleaning process on those areas.
Phase 2: Repair and Prepare for Sealing
This is a critical step. Don’t apply new sealant over old, cracked, or damaged areas.
- Remove Old, Cracked Sealant: Carefully use a plastic scraper or putty knife to remove any old, brittle, or cracked lap sealant around vents, skylights, and other fixtures. Be gentle to avoid damaging the roof membrane or the fixture itself.
- Clean Residue: After scraping, use a rag dampened with mineral spirits or acetone (check compatibility with your roof material first!) to clean off any remaining sealant residue. This ensures a clean surface for the new sealant to bond to.
- Address Minor Tears or Punctures: For small tears in rubber roofs, use a patch kit designed for your specific roof material. Follow the patch kit instructions carefully. For larger damage, consult a professional.
- Clean All Surfaces Again: Before applying any new sealants, ensure all areas, especially around fixtures, are clean and completely dry. Any moisture or dirt will compromise the new sealant’s adhesion.
Phase 3: The Sealing Application
Now for the protective layer. This is where your RV roof cleaning and sealing guide culminates in long-lasting protection.
- Apply Lap Sealant to Fixtures:
- Load your caulking gun with self-leveling lap sealant.
- Apply a generous bead of sealant over all seams, screws, and around the base of every roof penetration (vents, skylights, antenna, AC unit).
- The self-leveling sealant will spread and fill gaps, creating a watertight seal. For vertical areas, use non-sag lap sealant.
- Allow the lap sealant to cure according to the manufacturer’s instructions, which can take several hours or even a full day.
- Apply Roof Coating (if applicable):
- If you are applying a full roof coating (e.g., elastomeric or acrylic), ensure the lap sealant is cured and the entire roof surface is completely dry.
- Use painter’s tape along the edges of your roof where it meets the sidewalls to create a clean line.
- Pour a section of the coating onto the roof and spread it evenly with a roller. Use a brush for edges and around fixtures.
- Apply the coating in thin, even layers. Most coatings require two coats. Follow the manufacturer’s recommended drying time between coats.
- Once the final coat is applied and still wet, carefully remove the painter’s tape.
- Allow the entire roof coating to cure completely before exposing it to rain or heavy dew. This can take several days.
Tackling Common Problems with RV Roof Cleaning and Sealing
Even with the best intentions, you might encounter some challenges. Knowing how to address common problems with RV roof cleaning and sealing can save you time and frustration.
Mold and Mildew Buildup
This is a frequent issue, especially in humid climates or if your RV is stored under trees. Use an RV-specific cleaner designed to kill mold and mildew. A solution of white vinegar and water (50/50) can also be effective and more eco-friendly, but always test in an inconspicuous area first.
Stubborn Stains (Tree Sap, Tar, Bird Droppings)
For tree sap, try rubbing alcohol on a rag, but use it sparingly and rinse immediately. For tar, a small amount of mineral spirits can work, again, with caution and immediate rinsing. Bird droppings should be cleaned as soon as possible, as their acidity can damage the roof membrane over time. A good RV roof cleaner and a soft brush usually do the trick.
Cracked or Peeling Sealant
This indicates it’s time for resealing. Don’t just apply new sealant over old, cracked material. You must remove the old, compromised sealant first to ensure proper adhesion of the new. This is a crucial step for long-term protection.
Walking on the Roof Safely
Most RV roofs are walkable, but always check your RV manual. Distribute your weight evenly, step only on structural supports if specified, and avoid walking directly on skylights or vents. Use a plywood sheet to spread your weight if you need to work in a specific area for an extended time.
Sustainable RV Roof Care: Eco-Friendly Choices for the Conscious Explorer
As outdoor enthusiasts, we strive to minimize our impact. Choosing sustainable RV roof cleaning and sealing methods and products aligns with this ethos.
Eco-Friendly Cleaning Solutions
Look for biodegradable, phosphate-free, and non-toxic RV roof cleaners. Many reputable brands now offer such options. You can also make your own gentle cleaner:
- Mild Soap and Water: A simple solution of dish soap (like Dawn) and water can be effective for light cleaning.
- Vinegar Solution: As mentioned, a diluted white vinegar solution is great for mold and mildew.
Always rinse thoroughly to avoid leaving any residue, regardless of the cleaner you use.
Choosing Environmentally Responsible Sealants
While sealants are inherently chemical products, some manufacturers are developing more eco-conscious options. Look for:
- Low VOC (Volatile Organic Compound) Formulas: These release fewer harmful fumes into the atmosphere.
- Water-Based Coatings: Often easier to clean up and generally have a lower environmental impact than solvent-based options.
Research brands and read product labels to make informed choices. Supporting companies committed to sustainability helps drive the industry toward greener practices.
Beyond the Basics: Advanced RV Roof Cleaning and Sealing Tips for Longevity
Once you’ve mastered the basics, consider these RV roof cleaning and sealing best practices to maximize your roof’s lifespan and performance.
Regular Inspection is Key
Clean your roof at least twice a year, ideally in spring and fall. However, perform quick visual inspections more frequently – after every long trip, or after severe weather. Catching small issues early prevents them from becoming major problems.
Winterization and Storage Prep
Before storing your RV for the winter, ensure the roof is impeccably clean and sealed. Any lingering moisture or organic matter can lead to mold, mildew, or freeze damage. A fresh coat of sealant before winter offers maximum protection.
Don’t Forget the Edges and Gutters
Often overlooked, the edges of your roof and rain gutters can accumulate grime and debris. Clean these areas thoroughly to ensure proper water runoff and prevent staining on your RV’s sidewalls.
Consider a Roof Cover for Extended Storage
If your RV will be stored outdoors for long periods, investing in a breathable RV cover can provide an extra layer of protection from UV rays, tree sap, and environmental fallout, reducing the frequency of deep cleans and extending sealant life.
Professional Assessment
Even if you’re a DIY enthusiast, consider having a professional RV technician inspect your roof every few years. They can spot subtle issues you might miss and offer expert advice, especially as your RV ages or if you notice unusual wear.
Frequently Asked Questions About RV Roof Cleaning and Sealing
What types of RV roofs are there, and do they require different care?
Most RVs have EPDM (ethylene propylene diene monomer) or TPO (thermoplastic polyolefin) rubber roofs. Some have fiberglass or aluminum. EPDM and TPO require specific non-petroleum-based cleaners and compatible sealants. Fiberglass and aluminum roofs are more durable but still need cleaning and may use different coatings or paints. Always check your RV manual to confirm your roof type and recommended products.
How often should I clean and seal my RV roof?
Clean your RV roof at least twice a year (spring and fall), or more frequently if you travel often or park under trees. Inspect lap sealants every 3-6 months. Most full roof coatings last 5-10 years, but always refer to the specific product’s longevity claims and your roof’s condition.
Can I use a pressure washer on my RV roof?
No, avoid using a pressure washer on your RV roof. The high pressure can damage the roof membrane, loosen seals, and force water into seams, leading to leaks. A standard garden hose with a spray nozzle provides sufficient pressure for rinsing.
What should I do if I find a small tear in my RV roof?
For small tears (typically less than 6 inches) on rubber roofs, use an RV-specific roof patch kit. Clean the area thoroughly, apply the patch according to instructions, and then seal the edges with a compatible lap sealant. For larger tears or significant damage, it’s best to consult a professional RV repair service.
Is it safe to walk on my RV roof?
Most RV roofs are designed to be walked on for maintenance. However, always check your RV owner’s manual for specific weight limits or designated walking areas. Wear soft-soled, non-slip shoes, and distribute your weight evenly. Avoid walking on skylights or vents. If you’re unsure or uncomfortable, use a sturdy ladder and a long-handled brush from the ground or a scaffold.
