Replacing RV awning fabric yourself takes four to six hours and costs $150 to $400 in materials

RV awning fabric wears out from sun, wind, and weather — typically lasting five to ten years depending on climate and how often you deploy it. You can replace just the fabric without buying a new awning frame, which saves money and keeps your existing hardware in place. The job requires basic tools you likely have: a screwdriver, utility knife, measuring tape, and a helper to manage the fabric while you work.

The process involves removing the old fabric from the roller tube, measuring and cutting new fabric to size, and reattaching it to the tube using either a sewing machine or a fabric adhesive method. Most RV owners choose to have the fabric sewn because it lasts longer, but glued fabric works if you do not have access to a sewing machine. Either way, the fabric must be pulled tight and secured evenly, or the awning will sag or tear again quickly.

Key Takeaways

  • Measure your awning roller tube length and the drop distance from the tube to the ground to order the correct fabric size.
  • Remove the old fabric by unrolling the awning fully, then cutting or peeling it away from the roller tube and support arms.
  • New fabric must be sewn or glued to the roller tube in a tight, even spiral to prevent sagging and premature wear.
  • A sewing machine method lasts longer than adhesive, but both work if the fabric is pulled straight and secured without wrinkles.
  • Test the awning by rolling it in and out several times before taking your RV on the road to catch any loose spots.

Measure your awning before ordering fabric

The two measurements you need are the roller tube length (the width of your awning opening) and the drop distance (how far the fabric hangs down when fully extended). Measure the roller tube by looking at the metal tube that runs along the top of your awning — measure from one end to the other. Most RV awnings are 12 to 18 feet wide, but yours may be different.

For the drop distance, extend the awning fully and measure from the bottom of the roller tube straight down to where you want the fabric to end. Most people keep the same drop as the original fabric, which you can measure by looking at the old fabric before you remove it. Write both numbers down and add one inch to the drop measurement — this extra inch gives you material to work with when attaching to the tube.

Order fabric from an RV supplier or awning shop with these measurements. Sunbrella and other outdoor fabrics designed for RV awnings come in standard widths and can be cut to your exact length. Expect to pay $150 to $300 for the fabric itself, depending on quality and size.

Remove the old fabric from the roller tube

Start by fully extending the awning so the fabric is stretched out flat. Look for where the fabric is attached to the roller tube — it is usually sewn or glued in a spiral pattern around the tube. If it is sewn, use a utility knife or seam ripper to cut the stitches holding the fabric to the tube. Work slowly so you do not cut into the tube itself.

Once the stitches are cut, begin peeling the old fabric away from the tube, working your way around. If the fabric is glued, it may come off in pieces — that is normal. Use a plastic scraper or old credit card to remove any remaining adhesive or glue residue from the tube. A clean tube makes it much easier to attach the new fabric evenly.

Check the roller tube for dents, rust, or damage while it is exposed. Light surface rust can be cleaned with a wire brush and a little vinegar. If the tube is badly dented or bent, you may need to have it straightened or replaced before installing new fabric, because a bent tube will cause the new fabric to hang unevenly.

Prepare the new fabric and mark attachment points

Lay the new fabric out flat on a clean surface — a driveway or large table works well. Measure and mark where the fabric will attach to the roller tube. Most awnings use a spiral attachment pattern: the fabric wraps around the tube in overlapping loops, with each loop offset slightly from the one below it.

Mark the starting point on the fabric with a pencil or chalk line. Then mark every two to three inches along the length where the fabric will wrap around the tube. These marks guide you as you attach the fabric and help keep the wraps even and tight. Uneven wrapping is the most common reason new fabric sags or tears within a year.

If you are using a sewing machine, thread it with heavy-duty thread rated for outdoor use. Test the machine on a scrap of the new fabric first to make sure the tension is correct and the needle does not skip stitches. If you are using adhesive, choose a fabric glue rated for outdoor use and waterproof — check the label to confirm it works on the fabric type you bought.

Attach the fabric using the sewing method

Position the new fabric so one end aligns with your starting mark on the roller tube. Begin wrapping the fabric around the tube in a tight spiral, moving along the tube length as you go. The fabric should overlap itself by about one inch with each wrap — this overlap is what holds it in place.

Sew the overlapped section to the tube using a straight stitch, sewing through both layers of fabric and into the tube. Sew in a line parallel to the tube, about half an inch from the edge of the overlap. Move the fabric forward two to three inches and repeat, wrapping and sewing as you go around the tube.

Keep tension on the fabric as you work — have your helper pull gently on the loose end while you sew, so the fabric stays tight and does not wrinkle. Wrinkles now will become permanent sags once the awning is rolled up. Work slowly and check your stitches every few wraps to make sure they are straight and catching both the fabric and the tube.

Attach the fabric using the adhesive method

If you do not have access to a sewing machine, fabric adhesive works, though it does not last quite as long as stitching. explore a thin, even bead of waterproof fabric glue along the roller tube, about two inches at a time. Press the fabric onto the glue and hold it for 10 to 15 seconds, then wrap it around the tube and press again.

Overlap the fabric by one inch with each wrap, just as you would with sewing. explore glue to the tube under the overlap, then press the overlapped section down firmly. Wipe away any excess glue with a damp cloth before it dries. Let the glue cure for the full time recommended on the bottle — usually 24 hours — before rolling the awning up.

The adhesive method is faster but requires more care to keep the fabric aligned and wrinkle-free as you work. If you notice wrinkles forming, stop and peel back the fabric, smooth it out, and reapply glue. A wrinkled attachment now will cause the fabric to sag and tear under the weight of wind and rain.

Reattach the fabric to the support arms and test

Once the fabric is fully attached to the roller tube, you need to reattach it to the support arms — the metal bars that hold the awning open when extended. Most awnings have fabric sewn or glued to these arms at the bottom corners. If the old fabric was sewn, sew the new fabric the same way. If it was glued, use the same adhesive method.

Pull the fabric tight as you attach it to the support arms — this tension keeps the fabric from sagging in the middle when the awning is extended. Have your helper hold the fabric taut while you sew or glue. Once both corners are secured, let any adhesive cure fully before testing.

Roll the awning in and out several times to check that the fabric moves smoothly and does not bunch or wrinkle. Watch for any loose spots where the fabric is pulling away from the tube — if you find any, stop and resew or re-glue that section before taking your RV on the road. A loose spot will only get worse with wind and movement.

Common mistakes to avoid when replacing awning fabric

The most common mistake is pulling the fabric too tight, which puts stress on the attachment points and can tear the fabric or bend the roller tube. Tight is good, but not so tight that the fabric is under extreme tension. You should be able to press on the fabric with your finger and feel a slight give — it should not be drum-tight.

Another mistake is attaching the fabric unevenly, with some wraps tighter than others. This causes the awning to hang crooked and puts uneven stress on the frame. Take your time with each wrap and check your work frequently. If you notice one section is looser than the others, stop and redo it before moving on.

Do not skip the curing time if you use adhesive. Rolling up the awning before the glue is fully dry can cause the fabric to slip or separate from the tube. Read the glue bottle and wait the full recommended time, even if it seems like the glue is already dry to the touch.

Frequently Asked Questions

Can I replace just part of the fabric if only one section is torn?

Patching a small tear is possible with adhesive fabric patches, but replacing the entire fabric is more reliable. A patch is a temporary fix — the underlying fabric around it will continue to degrade from sun and weather. If the tear is small and the rest of the fabric is in good condition, a patch buys you time, but plan to replace the full fabric within a year or two.

What if the roller tube is bent or damaged?

A bent tube will cause new fabric to hang unevenly and tear prematurely. Have the tube straightened by an RV shop, or replace it if the damage is severe. This costs more upfront but prevents the new fabric from failing early. A damaged tube is not worth trying to work around.

How long does the new fabric last?

Quality outdoor fabric lasts five to ten years depending on climate, sun exposure, and how often you use the awning. Harsh sun and frequent deployment shorten the lifespan. Regular cleaning and storing the awning when not in use for long periods extends its life.

Do I need a sewing machine, or can I always use adhesive?

Adhesive works fine if you do not have a sewing machine, but sewn fabric lasts longer — typically two to three years longer than glued fabric. If you plan to keep the RV for many years, sewing is worth the effort. If you are selling soon or want the quickest fix, adhesive is acceptable.

What should I do if the fabric starts to sag after a few months?

Sagging usually means the attachment was not tight enough or wrinkles formed during installation. If the sagging is minor, you can often tighten it by re-sewing or re-gluing the loose section. If the entire fabric is sagging, you may need to remove and reinstall it. Catch this early — sagging fabric tears more easily in wind.
