Last Updated on After purchase, maintaining your treasured campervan is crucial for preserving its overall integrity and longevity. Over time, exposure to the elements can lead to wear and tear on the roof, making regular maintenance and well-timed repairs essential.
In this guide, we’ll show you the road map to keeping your motorhome roof seal in top condition – from routine inspections to handling common issues, ensuring your adventures remain worry-free and your vehicle stays protected.
Identifying and Addressing Damage to Your Motorhome Roof
Motorhomes are forever exposed to the elements, making them susceptible to damage over time – in particular, their roofs. From minor cracks and leaks to more significant structural issues, recognising the signs early can save you from costly repairs down the road. Equipping yourself with what signs to look out for can help in preventing further damage – and remaining ahead of issues overhead.
1. Inspect Regularly
Regular inspections are your first line of defence against roof damage. Look for common signs like discolouration, soft spots, or visible cracks. Pay special attention to seams, edges, and the area around any roof-mounted equipment, as these areas are prone to leaks and deterioration.
Many recommend inspecting a motorhome roof at least once a year, and if possible, twice a year in the spring and fall. Spring inspections can help identify weather damage after winter, while fall inspections can remove debris and allow for proper drainage before winter.
Tip: Consider extra inspections following situations after rough weather. Inspect your camper van’s or motorhome’s roof after exposure to hail, snow, drought, extreme heat, wind, or rain. Also, if you live in or travel through inclement weather conditions, you may need to commit to inspecting your roof every six months to catch small issues and action well-timed camper roof sealing.
2. Common Types of Roof Damage
Understanding the different types of damage can help you conduct effective inspections and fixes. Water damage, for instance, may manifest as mould, mildew, or sagging spots, while UV exposure can cause cracks and material degradation. Knowing what to look for will enable you to act as needed.
3. Addressing Minor Issues Before They Escalate
Small issues like hairline cracks or loose caravan roof sealing can escalate if not addressed soon enough. Use appropriate sealants and patches to fix these problems as soon as they’re detected. Regular motorhome roof repair, maintenance and quick fixes can prevent minor damage from turning into a major repair job.
4. Knowing When to Call a Professional
You can handle many repairs with a bit of DIY effort, however, there are times when professional intervention is necessary. If you notice extensive water damage or structural issues, or if you’re unsure of the extent of the damage – it’s best to consult a professional to ensure the roof is well-repaired and secure.
Essential Steps for Cleaning Your Motorhome Roof

Complete Guide to Resealing Your Motorhome Roof
Resealing your motorhome roof is essential for maintaining its durability and preventing leaks. Whether your roof features fibreglass, rubber, or another material, understanding the specific needs of each type will help you choose the right products and methods for resealing.
Key Considerations Before Resealing Your Motorhome Roof
Before resealing your motorhome roof, there are a few important factors to consider.
First, assess the current condition of your roof, including any existing damage or wear, to determine the extent of resealing needed. Next, choose the appropriate sealant based on your roof material and environmental conditions, ensuring compatibility and long-lasting protection.
Choosing The Right Sealant
When resealing a motorhome roof, the type of sealant you choose is crucial to ensuring a durable and effective caravan roof repair. Selecting the right sealant depends on your roof material and the specific repair needs.
New or recently manufactured models likely have a fibreglass roof. As for older or secondhand vehicles, the roof is more likely to consist of rubber, though it could also be steel or aluminium. Consult your vehicle’s manual to confirm the roof material to check you’re using the correct resealing method.
Here are the most common types:
- Silicone Sealant: This is very flexible and waterproof, which is ideal for rubber roofs, but not recommended for use on fibreglass due to potential adhesion issues.
- Acrylic Sealant: A versatile and UV-resistant choice, suitable for various roof types, including fibreglass and metal, though it may need more frequent reapplication.
- Polyurethane Sealant: A very durable sealant that is resistant to harsh weather, making it a great choice for long-lasting protection on most roof materials.
- Butyl Rubber Sealant: This make has excellent adhesive properties, and is perfect for sealing around vents, skylights, and other roof penetrations.
Tip: Once you select your sealant, be sure to plan the timing of your resealing project to avoid extreme weather, which can affect the application and curing process.
Step-By-Step Guide to Resealing a Fibreglass Motorhome Roof
Work through the following steps to reseal your fibreglass motorhome roof and reinforce a waterproof and well-protected motorhome.
- Clean the Roof Surface: Start with a thorough roof clean with a non-abrasive cleaner to remove dirt, debris, and any old sealant residue. Allow the roof to dry completely before proceeding.
- Inspect for Damage: Survey the roof for cracks, chips, or worn areas. Address any significant damage with appropriate repair materials before resealing.
- Remove Old Sealant: Use a plastic scraper or putty knife to remove any old or deteriorated sealant from seams, joints, and edges.
- Apply Masking Tape: To keep clean, straight lines, apply masking tape along the edges of the areas you plan to reseal.
- Choose the Right Sealant: Select a sealant designed for fibreglass roofs – such as an acrylic or polyurethane-based product.
- Apply the Sealant: Using a caulking gun, apply a continuous bead of sealant along seams, joints, and around any roof fixtures. Smooth out the sealant with a tool or gloved finger to confirm even coverage.
- Allow Sealant to Cure: Follow the manufacturer’s instructions for curing time, ensuring the roof remains dry and undisturbed during this period.
- Inspect and Test: Once the sealant has cured, inspect the roof to guarantee all areas are well sealed. Consider testing the seal by applying a gentle spray of water over the roof and checking for leaks.
Step-By-Step Guide to Resealing a Rubber Motorhome Roof
Though there are similarities to fixing a mobile home roof made of fibreglass, a rubber roof will have some unique method requirements.
Here’s a step-by-step guide to resealing a rubber motorhome roof:
- Clean the Roof Surface: Begin by washing the roof with a mild detergent and water to remove dirt, debris, and any old sealant. Rinse and let the roof dry completely.
- Inspect and Repair Damage: Check the roof for any cracks, tears, or worn areas. Use a rubber roof repair kit or patches to fix any significant damage before applying new sealant.
- Remove Old Sealant: Remove any existing sealant from seams and joints using a plastic scraper or putty knife. Ensure the surface is smooth and free of old sealant residues.
- Apply a Primer (if needed): Some rubber roof sealants require a primer to enhance adhesion. If the sealant you’re using specifies this, apply the primer according to the manufacturer’s instructions and let it dry.
- Choose the Right Sealant: Select a sealant designed for rubber roofs, such as a butyl rubber or acrylic sealant.
- Apply the Sealant: Using a caulking gun, apply a continuous bead of sealant along seams, joints, and around any roof fixtures. Smooth the sealant with a tool or your finger for even coverage and to ensure proper adhesion.
- Allow Sealant to Cure: Follow the manufacturer’s recommended curing time, keeping the roof dry and undisturbed during this period.
- Perform a Final Inspection: After the sealant has cured, inspect the roof to make sure all areas are well sealed. Test for leaks by applying a gentle spray of water over the roof and checking for any signs of moisture penetration.

FAQ
How often should you reseal your camper roof?
You should reseal your camper roof every 1 to 2 years, depending on factors like roof material, weather conditions, and how often you use your camper. Regular inspections (after extreme weather or otherwise, every year) can help determine if you need to reseal sooner, especially if you notice signs of wear or damage.
Why do camper roofs leak?
Camper roofs leak usually due to a faulty sealant and leaking caulk – which can lead to slow, but heavy damage if the leak goes undetected. Other causes can also stem from ageing and wear, improper installation, physical damage, weather conditions, clogged drains, and pooling water.
How to find a roof leak on a camper?
Finding a roof leak in a camper starts by searching and inspecting the vehicle’s interior for water stains and then backtracking along the damage signs to the source. Next, scan the roof’s exterior for any damage, gaps, or punctures while taking extra care near vents and seams. To pinpoint leaks, use a hose to test by simulating rainy/wet conditions.
