Replacing torn RV awning fabric is a two-person, one-afternoon job — far cheaper than a new awning. The fabric slides out of the roller tube and the awning rail in two channels, so the swap is: measure, safely de-tension the spring, slide the old fabric out, slide the new fabric in, and re-tension. This guide covers measuring correctly (the most important step), handling the spring safely, and fitting the new fabric.
Step 1 — Measure for the right fabric
Awning fabric is sized by the awning length (the measurement that matters for ordering), and the fabric is typically about a foot shorter than the stated awning size to fit between the end caps.
- Measure your awning's stated size (often printed on the arm) or measure tip-to-tip between the arms.
- Order the fabric for that awning length — the fabric width is sized accordingly.
- Note whether you have a fabric weather guard/cover too, which may need matching.
What you'll need
- Replacement awning fabric in your size — shop RV awnings & fabric
- A helper, a ladder, a cordless drill, and (recommended) locking pliers/clamps
- Soapy water or fabric lube to ease the new fabric into the channels
Step 2 — Safely release the spring tension (important)
The roller tube is under strong spring tension — handle it carefully.
- Extend the awning partway and lock the arms.
- Follow your awning brand's procedure to relieve/secure the spring tension on the roller end — do not let the tube spin freely.
- Keep hands clear of the roller as you work.
Step 3 — Slide out the old fabric
- Free the fabric from the arm/roller end and the awning rail on the RV.
- With your helper, slide the old fabric out of the channel along its length.
- Clean both channels (roller and rail) so the new fabric slides freely.
Step 4 — Slide in the new fabric
- Match the two polycord edges to the roller channel and the wall-rail channel.
- Lubricate the channels and feed the fabric in evenly, keeping it square as your helper guides it.
- Center the fabric so the overhang is even on both ends.
Step 5 — Re-tension & test
- Re-apply the spring tension per your awning brand's spec (too little and it won't roll up; too much strains the arms).
- Roll the awning in and out a few times to confirm smooth, even operation and no sag.
Common mistakes to avoid
- Mismeasuring — order by awning length, not the fabric length; confirm before buying.
- Letting the spring unwind — control the roller tension at all times; it can injure you.
- Forcing dry fabric — lube the channels so it slides without tearing.
- Uneven centering — center the fabric or it rolls up crooked.
Frequently asked questions
What size awning fabric do I need?
Order by your awning's stated length (often on the arm). The fabric itself is usually about a foot shorter to fit between the end caps — the listing accounts for this.
Can I replace awning fabric by myself?
It's doable but much easier and safer with two people, mainly because of the spring tension and feeding the long fabric evenly.
Is the spring dangerous?
The roller spring stores significant energy. Follow your brand's tension procedure and never let the tube spin freely — keep hands clear.
Do I need new arms or just fabric?
If the arms and roller are sound, fabric-only is the usual fix. Replace hardware only if it's bent or seized.
