Heavy Duty White Tarps

White tarps are 10 mil heavy duty waterproof poly tarps built for carport and canopy replacement, backyard, and all-weather cover. Unlike silver or silver/black tarps, white passes more light — so it's noticeably brighter underneath — and the clean white color gives carports, canopies, and patios a more elegant, finished look. Made by Sigman from woven reinforced polyethylene with UV-resistant coating on both sides, these are heavier than most white tarps on the market and true to thickness, weight, and size. White is one of three 10 mil colors in the MyTarp poly family, the bright, light-friendly alternative to the heat-reflective silver and the light-blocking silver/black.

Why choose white

Pick white when you want a brighter space and a cleaner look. White poly passes more light than silver, brown silver, or silver/black, so a carport, canopy, or patio stays lighter underneath instead of dim. The white color also reads as cleaner and more elegant for backyard and display use. At a true 10 mil with a 14 x 14 weave and 5.5 oz fabric, plastic-bar-reinforced corners, and UV coating on both sides, it holds up far better than the thin white tarps sold at hardware stores. MyTarp lists the actual measured thickness — the 10 mil you order is the 10 mil you receive.

For strong-sun states (FL, AZ, CA)

In high-UV climates like Florida, Arizona, and California, any poly tarp's life is shortened by intense sun. If you need maximum longevity, step up to a vinyl cover such as our 18 oz vinyl coated polyester tarps, which typically last about 4–6 years in FL, AZ, and CA.

Carport & canopy replacement covers

Worn-out carport or canopy top? These heavy duty white tarps are a popular replacement cover for metal carport and pop-up canopy frames. At a true 10 mil with a 14 x 14 weave and plastic-bar-reinforced corners, the white poly is waterproof and UV-coated on both sides — and because white passes more light, your carport, canopy, or patio stays brighter underneath than it would beneath a silver or silver/black top.

How to size a replacement cover: measure your existing frame, then pick a finished tarp that overlaps the frame on every side. Use the grommets — spaced about every 1.5 ft on all four sides and corners — to lash the new cover down tight with bungee cords or rope. Finished sizes run within 1–3 inches of the size listed.

10' x 10' White Tarp — pop-up canopy replacement top
10' x 20' White Tarp — flat-roof or low-pitch carport replacement cover
12' x 20' White Tarp — high pitch 10x20 or low pitch 12 x 20 carport & canopy cover
20' x 20' White Tarp — large canopy replacement top
20' x 30' White Tarp — oversized carport cover

Frequently Asked Questions

What are heavy duty white tarps best used for?

Heavy duty white tarps are 10 mil waterproof poly tarps best for carport and canopy replacement, backyard and patio cover, equipment protection, and any job where you want a brighter, cleaner-looking cover. White passes more light than silver or silver/black, so it stays lighter underneath, and the clean white color gives a more elegant, finished look.

Are white tarps good for carport and canopy replacement?

Yes. At a true 10 mil with a 14 x 14 weave and plastic-bar-reinforced corners, white tarps are a popular heavy duty replacement for worn carport and canopy tops. Measure your existing canopy and pick a finished size that overlaps the frame on all sides, then use the grommets every 1.5 ft to lash the tarp tightly to the frame.

Do white tarps let light through, and is it brighter underneath?

Yes. White poly passes more light than silver, brown silver, or silver/black tarps, so the space under a white carport, canopy, or patio cover stays noticeably brighter rather than dim. Choose white when you want a lighter, cleaner feel underneath; choose silver/black when you instead want to block light fully.

How thick and heavy are these white tarps?

These are a true 10 mil thick with a 14 x 14 weave count and 5.5 oz/sq yd fabric weight, made by Sigman from woven reinforced polyethylene and UV-coated on both sides. They are heavier than most white tarps on the market, so they hold up far better than the thin white tarps sold at hardware stores.

How does white compare to silver and silver black at 10 to 11 mil?

All three are heavy duty poly. Choose 10 mil white when you want a brighter space underneath and a clean look. Choose 10 mil silver for a heat-reflective canopy, roof, and equipment cover. Choose 11 mil silver/black when you want a heavier tarp with a blackout-black side that blocks light completely. White is the bright, light-friendly option in the lineup.

How long will a white poly tarp last in strong sun like FL, AZ, or CA?

In high-UV climates such as Florida, Arizona, and California, intense sun shortens the life of any poly tarp. The UV coating on both sides helps, but for maximum longevity in those states, step up to a vinyl cover such as an 18 oz vinyl coated polyester tarp, which typically lasts about 5 to 6 years in FL, AZ, and CA.

What size white tarp do I need?

Measure the area or canopy frame you need to cover and allow extra material on each side for overlap and tie-down. White tarps come in 25 finished sizes from 5' x 7' up to 40' x 60', including common carport and canopy sizes like 10' x 20', 12' x 20', and 20' x 20'. Because these are finished-size tarps, the actual size is usually within 1 to 3 inches of the nominal size listed.

White heavy duty vs Made-in-USA poly, which should I choose?

Choose 10 mil heavy duty white for a strong, affordable, bright carport and canopy cover for seasonal to medium-term use. Step up to a 12 mil or heavier Made-in-USA poly tarp when you need the longest outdoor service life, or to an 18 oz vinyl tarp for maximum longevity in high-UV climates.
