Carport Structural Material(s)

Your carport selection will primarily hinge on its structural material(s). It’s essential to check the quality and durability of the product before purchasing. The roof must be sturdy enough to withstand winter storms.

Aluminum or galvanized steel both make for great choices: they’re lightweight, low maintenance, durable, and retailed in an array of colours fit for your home. These materials are easy to install and don’t mandate intense masonry work.

Roof Material Selection 

The carport’s roof will influence rainwater drainage and the exterior look of your home. Often, you’ll have the choice between a sloped roof or a flat roof. A flat roof is curveless and, therefore has no pitch. Its overall look perfectly suits modern architecture. On the other hand, a sloped roof may be more suited to rainy regions or those exposed to snowfall. Moreover, leaves won’t stagnate on the rooftop come fall. 

As for roof materials, choices aren’t lacking, that’s for sure. From steel to tiles, with asphalt shingles in between, there’s something for everyone. Another worthwhile option is installing a polycarbonate roof covering. The latter can withstand rain, snow, hail, and falling tree branches. Said material is very sturdy and guarantees durability and extreme weather resistance. Additionally, polycarbonate panels block harmful UV rays and provide sufficient shade to better protect your vehicle.

Attached Carports vs. Freestanding Car Shelters

A well-built carport will help improve the look of your house while also significantly increasing its resale value. This is all the more true when it comes to a car shelter that’s directly attached to your home. However, note that some house-adjacent shelters are more expensive than freestanding carports. There’s a simple explanation: your shelter will be considered an extension of the house, and if you’re ever tempted, easier to convert it into an enclosed garage at some point down the line.

Labour

Much like all building projects, hiring professionals will increase the overall cost. While a DIY approach isn’t far-fetched, depending on the purchased carport, it’s always highly advised to spend a little more to guarantee a job done safely and correctly the first time around.

Permits

First things first, check with your municipal authorities to determine which permits are required to build or install a carport. Since every city has a specific set of regulations, it’s important to consult the concerned authorities to guide your project in the right direction. Otherwise, you risk facing hefty fines.

Once you’ve secured a permit, you can start designing your carport. Some prefab carports can easily be installed, but you can also choose to build your carport from scratch. Moreover, quite a bit of decision-making is involved in determining if the carport will be adjacent to your home or freestanding. Depending on several factors and conditions, your project's plan and building permit should cost you between $300 and $3,000.

Secure the Structure

Should the carport be exposed to various potentially damaging elements, such as strong winds, pour a concrete slab foundation or secure the structure using screw piles.
