How To Maintain TPO RV Roof?
Regular maintenance of the TPO roof of your beloved RV can ensure a healthy and long sustainable life of the roof. Inspection, cleanliness, awareness and proactiveness can work wonders on maintaining your roof health.
Check out the extensive guide below we have put together about the maintenance of your TPO roof.
1. Establishing a Regular Inspection Program
The first and foremost step for this maintenance activity is to be updated about the condition of the roof constantly. Regularly check out the surface of the roof so that nothing can affect the roof for an extensive period of time.
If you find any signs of damage, repair it right away to minimize the possibility of it getting worse.
Inspect and ensure the seams are tightly joined. Make sure there is not a big mess of fallen leaves, dirt and debris accumulating on the roof surface. Trim off any long tree branches around the roof.
2. Cleaning The TPO Roof Regularly
Keeping the roof surface clean can extend the lifespan of the roof by a long shot. It will prevent any kind of infestations or dirt build up on the surface.
If you are a regular user, it is best to clean the roof every three to four months for essential maintenance. Below is a step by step detailed guide on how to clean the TPO roof of your RV:
- First off, park the RV close enough to a water hose for easy washing access.
- Start by washing off all the dust, dirt and debris using a pressure power washer 2,000 PSI or under.
- Get a bucket full of a gallon of cold water.
- Mix 6 to 10 ounces of a mild non abrasive detergent or cleaning solution with the water to create a TPO safe cleaning solution.
- Choose a push broom with soft bristles and start sweeping from one side of the roof.
- Make sure to sweep all the dirt in one direction towards the drain for easy clean up.
- Once sweeping the entire roof, use the pressure washer and wash off the accumulated dirt from the roof.
- Repeat this same cleaning process as many times as necessary until all the dirt is completely cleared away.
- Rinse away all the cleaner from the roof using the water hose.
3. Installing A Good Drainage System
Since the RV roof is completely flat, it needs a proper drainage system to function. Otherwise, rainwater or snow will gather around on the roof without any actual drainway to go into. As a result, the roof will get pools of water which will damage it.
Install a proper drainage system with gutters and downspouts that lead outside. Check it periodically to make sure that no debris or dirt is blocking the drainway.
4. Apply A Protective Coating On Top Of The Roof
To improve the lifespan and durability of your TPO roof, it is recommended to apply a layer of protective material on top. Not all kinds of coatings are suitable for a TPO roof because of the chemicals mixed inside that might react negatively.
If the TPO roof has already suffered previous damage, applying several layers of coating is the best course of action to save it.
Acrylic coatings and asphalt emulsion coatings are good choices as a protective layer on your TPO roof.
These materials can withstand hail, snow, rain, high temperature and protect the roof from all these rough environments. You can also choose fluid coatings in order to avoid the problem of pooling water.
5. Repairing Any Damage To The Roof
On a regular inspection, you might find holes, tears or damages to the surface of the roof. Instantly repair any of these damages you find using a suitable sealant.
A water based cement of high quality might be a good choice as a sealant to patch these damages up. It is an effective sealant which is long lasting and waterproof.
In case the damage is too much and irreversible, you can implement the Fluid Applied Reinforced Roof (FARR) system to your TPO roof. It is a high quality and sustainable system that restores the health of the roof.
