Factors to Consider When Buying Lumber for Pergola

A pergola is an excellent addition to outdoor space, adding architectural interest and providing shade. It would be best if you researched thoroughly to achieve optimal value for your hard-earned money.

Here are some essential factors to consider when shopping for a pergola.

The amount of shade you want your pergola to provide

The shade offered by your pergola will be determined by its location in your backyard, plus the spacing between the rafters and planks that comprise the pergola roof.

The more closely spaced the slats and rafters are, the more shade protection they’ll get. Add canopy shade or lattice to increase the amount of shade.

Even though a pergola offers filtered shade, there’ll be hot and rainy days. A high-quality pergola kit may include a retractable canopy, allowing you to choose between shade and sunlight.

If you don’t think about a ceiling until after you’ve constructed a pergola, you’ll have to do the additional project to measure and install it.

Climate

The weather and other environmental factors in your locality directly impact your pergola. A pergola made of inappropriate wood will rot faster than expected if you reside in a humid climate.

Cedar gives you the best other wood options in such wet weather. It’s rot and insect resistant and will look great without the considerable expense of different wood types.

Pergola Kits vs Building a Pergola

How to Protect and Maintain your Wood Pergolas

Clean your pergola routinely

Clean your pergolas with a water solution and mild soap regularly regardless of the make or model. Regular cleaning prevents buildup and also enhances the general appearance of the structure.

Stain and seal pergolas

Trim the vines occasionally

Climbers are commonly grown along with pergolas. A touch of foliage undoubtedly brightens the atmosphere. However, vines thicken and add unnecessary weight to the pergola.

Although most pergolas can withstand weights, it is advisable to trim the vines at least twice a year. This will lighten the load on the frame while leaving the vines alone.
