All cedar structure is as beautiful as it is tough...

Don't let how pretty it is fool you... cedar is one tough wood. Whether you seal it or not, cedar will outlast every other N. American species in outdoor use. Sealed, it will maintain its golden color. Unsealed, it will patina to a natural grey/silver look. Our joinery methods are tough too and have been proven so in over 10,000 of our coops... in service in all 50 states.

Large hand-crafted panels are made from culled custom milled Grade 1 Western Red Cedar
Wall panels attach with provided 3" ceramic screws into pre-drilled holes with your cordless drill.
All door hinges come pre-attached
Pre-attached roof panels on a unique scissor frame allows installation from ground

Roost & Root Slant-Roof Greenhouse™

Twin-Wall PolyCarb & HDPE wall panels…

We dado cut slots into the cedar lumber frames and then install precision CNC cut Twin-Wall Polycarbonate clear panels into upper wall sections. Lower wall sections have recycled black HDPE food grade plastic inserts for splash protection and protection from objects shot out from mowers.

UV Protected ultra clear 6mm Polycarbonate wall panels transmit more light than any other brand
Clearer than most glass, withstands high heat and super sub zero temperatures
3/16 thick solid HDPE panels on bottoms provide strength, splash protection and are puncture proof
Cedar / Black HDPE "look" is designed to match our Raised Vegetable Garden bases
Wind tested to 80mph... these panels don't only look great, they're virtually indestructible
Large sized individual panels make for fewer pieces to assemble

Roost & Root Slant-Roof Greenhouse™ (raised gardens sold separately)

We hope you think it's just pretty. But it's more...

Our slant-roof design has benefits that are more than just beautiful. At a 25° slant, it will help shed all but the stickiest of snow and ice. That's a good thing. Heat naturally flows to its tall side which makes venting it more certain. Speaking of the tall side, it also provides loads of headroom. Seven feet to be exact. And no other design provides more evenly distributed, longer periods of optimal sunlight than a slant roof.

Provides greatest light and heat during sunlight transit from east to west
If snow accumulates, its easily knocked off as the roof remains flexible even in sub-zero temperatures
Heat naturally collects to the high side and can be collected or exhausted
Provides low wind resistance by allowing gusty winds to blow over the top
Naturally provides for high watershed rates
5 foot high on the low side, 9 foot on the high side, and 7 feet of headroom in all working spaces
The shape lends itself to the easy out-of-the-way installation of necessary shade cloths

Roost & Root Slant-Roof Greenhouse™ Pre-made Hinged Roof Installs From Ground

A crazy idea that works marvelously...

How do you ship a 10 foot long roof panel in a truck with only 7 feet of door height? Who wants to climb up on a 25° degree slant roof? All those roof screws, what a pain. Our answer? Make each roof section fold, "scissor" the top edge into place and lay the bottom edge on the short wall. All from the ground. For sure takes two strong people, but way better than getting on top 🙂

Panels are preinstalled on scissor style frames that can be installed from the ground
Pre-made panels means no climbing on top during installation
Preinstalled closure strips keep out unwanted guests
USA Made TuffTex© Polycarbonate panels are ultra clear, hail proof and long lasting
Ships to you in three preassembled sections ready to install

It's our first greenhouse, but not our first rodeo.

With 10,000 plus Chicken Coops and Raised Gardens spread all over the country, we know a thing or two about building. No body makes bigger more sturdy cedar framed kits than Roost & Root. The Slant-Roof Greenhouse™ is made from proven materials and proven methods just like everything we sell.

Proven cedar lumber panels and fastening system won't fail over time
Black HDPE & Poly Twin-Wall panels are dado inset and won't blow out unexpectedly
Suspended roof system can hold at least #800 like it would be with snow and ice until cleared.
Design has excellent wall rigidity due to panel construction and wall to roof bracing
Doors have high quality brush style seals to keep out bugs and drafts
Generous roof overhang is appealing but also keeps areas nearest structure free of run-off
Standard ventilation accommodations will be suitable for many users and a variety of growing scenarios
Thoughtful purpose-built accessories allow for customizations to suit diffident users and applications

Roost & Root Slant-Roof Greenhouse™

It's your space, you decide how to use it...

We picked the shape of the new Slant-Roof Greenhouse™ with the idea of giving you a wide range of options on how it gets used. Whether you plan to do seedlings, grow herbs, start vegetables early for transplanting, or you like growing flowers... wide open spaces and generous ceiling heights make just about anything possible.

5' high back wall with your 18" to 24" wide shelving puts you standing with 7' of headroom to work
7' high front wall allows for taller shelving but still leaves space above for warmer air
Either of our 24" wide raised vegetable gardens ( 4' or 8' models) will fit lengthwise
Even with both sides chocked full there's generous space in the middle to work from
Strong roof structure provides additional space to hang planters from

For those times when things get a little too hot...

It's probably the idea of a warm place to start plants that motivates you to buy a greenhouse. But you'll quickly find, that on a sunny day, the Slant-Roof design can make a 50°F or even more increase in temperatures quickly. In even moderately warm days, too much sun can overheat your greenhouse!

Custom sewn shade cloth in easy to install 2 piece design
Magnetically attaches using sewn in protected rare-earth magnets
Available in a 60% block weave
Made from ultra long lasting commercial grade polypropylene fabric
Sewn with black UV bonded polyester thread
All hardware is included

Outstanding passive ventilation features...

A big part of operating your greenhouse is to keep the air flowing in and out. Not everyone will opt for our Active Ventilation Management AVM system due to cost, or just wanting to be a purest. No worries, we've got your back... and your front too!

Large vertical front panels on each side allow heat that rises on high side to vent out
Lower back wall intake vents are positioned to draw from natural heat rise under roof
All vents have large mesh screen that allows bees and lady bugs in but keeps birds out
Back vents have our beautiful hand-crafted cedar wood louvers
Finer mesh screen is easily added by customer to control smaller insects if desired
Additional ventilation can be affected by the purchase of our inexpensive magnetic mesh door screen.

... and even more purpose made accessories.

Not everyone lives in the same place (duh) or plans to use their greenhouse in the same way (duh) and it is with that in mind that we built both standard and optional features. You buy what you want for where you live and how you plan to use the greenhouse.

Boardwalks - All cedar boardwalks QTY 2 are pretty and also serve as a dry place to work from. If you run cords into your greenhouse, they can also be run under the boardwalks to cover them.

Magnetic Closure Door Screen - Allows you to leave the door open for extra ventilation but keep birds out.

Regional Info

Use of a greenhouse is extremely diverse and the skills required are affected by, among other things, region and the plants you’re wanting to grow. The Slant-Roof Greenhouse™ design anticipates a set of factors that are influenced by regions. We hope the following will help you to understand better what to expect from your new greenhouse.

Considerations for Zone 2

We do not recommend the use of this greenhouse in Zone 2 areas. The exception would be if you were to apply supplemental heat if needed, or were planning to use the greenhouse in a narrow season.

Considerations for Zones 3-5

Snow Load: The 25° pitch roof should in many circumstances shed snow on its own, especially if the interior warms up significantly during the day or supplemental heat is used to avoid freezing. If significant amounts of snow accumulates, we would recommend periodically knocking it off. The back edge of the roof is extended enough that we expect the snow that slide off to not pack against the back wall. We load-tested the roof with #800 lbs of sandbags equally distributed and it deflected an acceptable amount.

Use of supplemental heat would be required in extended periods of below-freezing weather and may not be practical for some users. In higher temperature months, you will need to utilize 60% shade cloth to keep temperatures down due to the highly effective roof design and its ability to create heat inside the structure.

Considerations for Zones 6-9

In these more moderate climate zones, we would expect you to use your greenhouse in all but the hottest of months. In higher temperature months, you will need to utilize 60% shade cloth to keep temperatures down due to the highly effective roof design and its ability to create heat inside the structure. During the summer months, you may need to use extra ventilation to avoid too much heat.

In short spurts, you might need to provide supplemental heat in the middle of a harsh winter storm to avoid freezing.

Considerations for Zone 10

We do not recommend the use of this greenhouse in Zone 10 areas without using a 60% or greater shade cloth during the hottest months to block hot sunlight and considerable attention being given to ventilation.

What to Expect
Our goal is for the purchase of your new Slant Roof Greenhouse™ to be as surprise free as possible. In our “What to Expect” section we take our experiences with 10,000 + conversations with customers and try to outline things we’ve learned are consistently  important. And of course, if there is some concern that we’re not addressing, just call us at 877-741-2667 and we’ll help you out in person.
Read carefully all the information about a product.  We’re not trying to hide anything, but to keep web pages less cluttered, many details are organized in tabs or toggles.
Carefully review information on your cart page. We try to answer questions there too.
Wherever you see the info icon or “Note”, we’re  trying to bring something to your attention.
Most of our products are delivered via freight because of their large size. We package your purchase carefully to protect it during transit. How your item is treated after it leaves our facility is outside our control, but we will make right any shipping damage whether its our fault or not.
Shippers will contact you by phone to arrange for your order to be dropped off at an accessible location at the delivery address.  Products are designed so that individual pieces can be transported by hand to their final place of assembly.

Written or digital instructions are provided for each order and “assembly overview” videos are available for most everything we sell to give customers a good idea of what is involved in assembling your purchase before you buy. Most of our products are designed to be assembled by 2 people and in all cases, by people of ordinary skills. We rely on you having a cordless drill, maybe a hammer, and in some cases, a tape measure.
We try to write instructions for a balance of visual and written use. If you hire a contractor, you’ll want to make sure they read instructions too.  Our products cannot be assembled without using the instructions as intended.  If you or your contractor do have problems during assembly, you can either call or text us.
The Solar AVM system cannot cool your greenhouse more than the outside temperature.  It ventilates.  If you require cooling, you may need to use a small properly ventilated air conditioning unit in addition to the AVM.
Accessories are made to work with our products.  We do not warrant their use with products other than those that they are intended for.
Temporary snow loads of less than 20 lbs per square foot on the roof have been accounted for. That’s a lot of snow.  However, snow should be knocked off often when possible. Icing on edges of roof may need to be addressed as well.
