Replacement Canopy Tops: How To Measure.

Purchasing a canopy kit from your local retailer will require you to consider the replacement options at a later date. Most poly tarps sold with packaged canopy kits will last an average of 2-3 years before replacement is required. The most common problem when shopping for a replacement canopy top is the measuring process. The fact that the majority of canopy kits sold at local retail stores are of the high peak roof variety is helpful when shopping for your new carport cover. It is important to note that the frame width and length is not necessarily the replacement tarp size that is needed for your structure.

High peak canopy frames have a 120-degree rise in the roof pitch. As the roof angle increases so must the length of material to maintain the desired width. For example, on a 10’ x 20’ canopy frame with a common high peak roof, a rafter length of 5’ 8” is required on each side of the tent to maintain the 10’ width. As the rafter length increases so must the amount of material used to cover the canopy tent structure. Using the 10’ x 20’ example from above, the actual size of the replacement canopy cover would be a 12’ x 20’. The two extra feet is required to compensate for the rise in the peak.

A few important measurements can be extremely helpful when shopping for a replacement canopy top. The first and most important measurement is your canopy width and length. The second measurement is both your leg height and the height from ground to the center at the highest point of the roof rafter (usually where the roof meets at the top). The final measurement is over the peak of the canopy frame. Start from one corner fitting and measure up and over the peak to the other corner fitting. This will give you some idea of how much fabric is required to cover the peak.

Once these measurements have been taken you will be able to determine the roof style as well as, the amount of fabric needed for a replacement canopy top. It is always best to consult with a canopy and tarp specialist before making your final purchase. By using these helpful tips shopping for a replacement canopy top should be effortless.
