XL Slant-Roof Greenhouse
* Any accessories ordered at time of your greenhouse purchase ship for no additional cost.
Excellent communication with the timeline of when my slant-roof greenhouse was being built and shipped. The quality and craftsmanship is excellent. I’m so happy I decided to purchase from Roost & Root… D. Baxter – Lincolnton, North Carolina

×Convenience Options
Integrated into the design of the XL Slant-Roof Greenhouse™, is the ability to add our custom manufactured Automatic Ventilation Management System. The AVM makes more certain that adequate airflow occurs in the greenhouse to exchange out the oxygen saturated air and bring in carbon dioxide rich fresh air.
Even if you live somewhere cold, the need to exchange air in a greenhouse is required for optimal results. An automatic system can allow you to control heat (or cold temperatures) more precisely than just leaving doors open for ventilation. Not for cooling in summer heat.

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
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 panels transmit more light than other brands
Clearer than most glass, withstands high heat and super sub zero temperatures
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
3/16 solid HDPE panels on bottoms provide strength, splash protection and are puncture proof
We hope you think it's 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. Heat naturally flows to its tall side which makes venting it more certain. It also provides loads of headroom. Seven feet to be exact, no other design provides more evenly distributed, longer periods of optimal sunlight than a slant roof. (standard model shown)
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
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 Polycarbonate panels are ultra clear, hail proof and long lasting
Ships to you in three preassembled sections ready to install
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. (standard model shown)
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 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 4 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.

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’s of thousands of customers and try to outline things we’ve learned that 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 the 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 it’s 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 instructions are provided for each order and “assembly overview” videos are available for almost 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, a step-ladder or a standard ladder, and in some cases, a tape measure. Digital copies of the instructions are on each product page and also on the assembly support page. 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 as intended without using the instructions. We never want you or your contractor to struggle or guess at assembly, if something is unclear, please contact us: By phone 877-741-2667 x 3 or text 512-334-6610. 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 if you’re trying to significantly cool your greenhouse. The purpose of the AVM is active air exchange.
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 ~ 24″ – 30″ deep ordinary snow on the roof have been accounted for. That’s a lot of snow. However, snow should be knocked off often when possible. The icing on the edges of the roof may need to be addressed as well.

Yes, Roost and Root greenhouses are worth it for serious gardeners tired of flimsy, short-lived imports that collapse under wind or snow, wasting your time and plants. Key reasons a premium Roost and Root greenhouse surpasses the competition:- Top-tier materials that last: Made in the USA with no-maintenance top-grade cedar wood (far superior to cheap, treated pine that rots quickly) and durable poly-carbonate panels, outlasting thinly framed alternatives by years while maintaining their beauty.
- Exceptional craftsmanship for reliability: Precision-built with built-in ventilation and complete hardware kits— no shortcuts like weak joints or poor sealing found in low-end models—ensuring optimal performance in all seasons.
- Low maintenance design saves you effort: Naturally resistant cedar and robust construction mean less cleaning, fewer repairs, and no constant fixes for tears or leaks, unlike cheaply made plastic-sheet greenhouses that demand ongoing attention.
- Optimized for maximum growth: Slant-Roof and Heritage designs capture more heat and light for higher yields and extended seasons, with options like solar-powered ventilation—delivering results that budget options can’t achieve without add-ons.
- Hassle-free assembly: Smart Kits™ make setup straightforward for DIYers, avoiding the assembly nightmares of confusing, incomplete competitor kits.
