The spaces between your outdoor decking boards are meant to serve as a drainage system. They essentially prevent puddles formation and allow the surface to dry faster after rain. Besides the waterproofing application, your decking material can be easily preserved. However, if you're interested in reusing the space, you can easily convert the space into a beautiful patio by installing a gutter system along with an under-deck roof.

As you get this project started and finished, you're going to need a couple of important tools. These are as follows:

  • Cordless Drill
  • Circular Saw
  • Safety Glasses
  • Drill Bit Set 

​Along with tools, you're also going to need a specific set of materials. These include the following:

  • Gutter And Downspout
  • Roofing Screws
  • Fiberglass Panels 
  • Pressure Treated 2x4s

Under Deck Design


Under decks can be built to suit any design that you have. However, you must include a drainage system in order to keep the space dry. An under deck roof can be built at a low cost and the drainage system is designed to catch dripping water and redirect it on the outside of your deck. These covered areas can then be used as a beautifully designed covered patio.

Covered patios make the perfect setting for enjoying summer rainstorms without being drenched in the rain. However, there are commercially built systems that can be used as a waterproof decking system. They serve the same purpose of creating a cozy dry space under your deck. An under deck roof is very cost-effective and easy to build with materials that you have at home.


So if you're interested in building your own under deck roof, read on as we dive into it.

To get the process started, you're going to need to attach a pressure-treated 2x4 to spacer blocks. In doing this, you're going to be creating a gentle slope from the front to the back of your deck joist. Then you're going to need to screw the fiberglass panel to your 2x4 purlins.

Gathering Materials For The Drainage System


If you're on the hunt for materials, you can easily use corrugated fiberglass panels. These can be found at any local home center and they work perfectly. These panels generally come in a 12 ft long by 26 in wide. When attaching the panels, it's best to use special hex-head roofing screws with sealing neoprene washers.

 

You don't need to look too far because you can easily get them anywhere at a store that sells fiberglass or steel roofing materials. Instead of the fiberglass panels, you can substitute them with plastic roofing panels or galvanized steel. Just like the fiberglass panels, any other panel can be installed in the same fashion.

As support for the panels, you can easily screw the treated purlins to your installed spacer blocks as you create the previously mentioned slope. If rainwater already drains out into the lawn, then you don't need to install gutters. However, if the water gushes straight into your patio area, gutters are perfect for preventing a mess.

If you're considering what type of gutters to choose, PVC gutters are usually the best option. This is because they are pretty easy to install and cut if ever you need to alter them. If you're planning to install gutters, you're going to also need end caps, gutter straps, downspouts, a downspout outlet, PVC glue and of course the gutter itself.


Attaching Your Purlins


The first main step in building your under deck roof is attaching the purlins. Before you can install the purlins, you're going to need to plan and space them parallel to your house with 3ft in the center. As you proceed to create a drainage area, you're going to need the panels to slope toward the decks outside edge. This can be done at roughly 1/4 inch per foot.

If the under-span of your deck is 12 ft, then you're going to need to ensure that the purlins attached to the outer ends are 3 inches lower than the ones attached to the house. To make this easier, you're going to need to make markings on the deck joist that indicate the locations of the purlin. After you've done this, you'll need to install the outer purlin as well as the one alongside the house.

In order to measure the distance, you're going to need to stretch a string between them. You'll need to measure and mark the distance from the joist to the other purlins. These measurements are essentially the widths of your spacer blocks that were mentioned earlier. After cutting the spacer blocks, you'll need to screw them to the joist where you made the marks; at this point, you're ready to attach the remaining purlins to your spacers with the roofing screws.

Screw The Panels To The Purlins



In order to attach your fiberglass panels to set up, you're going to need to start at one end. As you position the screws, you'll need to place them at every other impression. When you begin to tighten the screws, be sure to tighten them enough so that they press into the washer a bit. Next, you're going to need to overlap another panel onto the one you've already installed.

To attach this new panel, you're doing the same thing that you did for the other one. This will ensure that your deck is waterproof. As you get closer to the end of your deck, you may notice that the last panel is a bit longer than it should be. You can simply overlap it or even cut it so that it fits nicely into your space; if you're cutting the panel, you can do so wit a carbide blade or a circular saw.

Install Gutters And Downspouts

If you need to install gutters, be sure to plan ahead and leave sufficient spacing for them. Before you even get to this step of the process, it's easy to design your own method of attaching them. This is usually done based on the design of your deck. You can easily screw the gutter hangers to the purlins as you create a slope to lead the water out through your downspout.

What Can You Do With Your New Patio Space?

If you're interested in entertaining guests, you can do so with your new patio. Your guests will love any warm or chilly afternoon under your new patio as you all sip on wine or tea or any other beverage that suits the atmosphere. Even if you're not entertaining guests, you can easily enjoy the open-air setting as you read a book or simply have some alone time.

Patios make a great spot for a fireplace around an elegant flagstone patio. The finish of this depends on your taste and what you prefer. However, most homeowners use hard surfaces to create that special look and feel.

While you're getting acquainted with your inner designer, you can even convert your patio space into a brick patio. Even if they aren't dazzling to others, you'll feel pride in knowing that you created this space with your own two hands. Several brick patterns can be easily installed in this area. Brick patterns are generally very intricate and have several designs.

Your new patio is the ultimate space for you to design it however you desire. You can even get your zen on with some pretty colorful trees. While trees are great, it might be best to place them in pots so that they don't mess with your handy brickwork. However, if you've used other materials for your patio, then planting trees around is completely fine; in creating your own mini garden, it's best to keep in mind that you'll need to maintain it from time to time.

If you're not a fan of maintaining those big trees we just mentioned, you can easily add some bulb plants. Tulips are an all-time favorite and can be added to enhance your patio. These can be grown in pots or in the ground if you prefer. When selecting plants, its also a good idea to choose them based on the season.

With the addition of flowers and even foods, you'll also be attracting bees into your new space. If this happens, you'll need to use some caution cause you might need to deal with a sting or two as they settle in for all things sweet. Besides the bees, you're also going to need to prepare for the mosquitoes at night. Mosquitoes can be easily dealt with if you have a fireplace; if you don't have one, you can use some repellant.

Your patio can be created to suit any design that you desire. You can go for something warm and cozy or you can even design to better suit the chilly breeze.

As we conclude, we have just looked at how to build an under deck roof. After building your under deck roof and drainage system, you can easily turn the space into a beautiful patio. Patios can be used for several different activities including entertaining guests and even relaxing.

Factors to consider when choosing a snow removal rake

1. Length

When choosing the right rake, it is vital to consider the height of your roof in relation to the length of its handle. Snow removal rakes are extendable, so you should look at the maximum extension length of the handle.

However, most rakes are not very useful when extended to their full length; hence you should choose one that you don't have to stretch to its full extent to reach your roof.

2. Design

​The design of the rake significantly affects its comfort ability and effectiveness. It is better to choose a rake with a design that offers a good grip and doesn't get stuck on your roof edge. Also, rakes can cause damage to your roof shingles; hence you should choose one that won't damage your roof.

Curve-bladed and wheeled rakes are the best at protecting your roof.

3. Weight

​The weight of the rake has great significance on the level of comfort it provides and proper handling. Heavy rakes are very uncomfortable to use and also make you fatigued. You should go for a lightweight rake, but be sure to check the materials it is made of as a material like wood breaks when subjected to a lot of weight.

4. Durability

​Nobody wants to see their money go down the drain; hence you should consider buying a rake that doesn't break or rust. Rakes with aluminum handles and polyethylene are the most durable as they are not susceptible to rust and breakage.
