Magnolia Outdoor Living Underdeck Questions and Answers PDF Print E-mail
What materials are used in your system?

All of the components of the Magnolia under deck ceiling system are manufactured from aluminum. It is the preferred material for underdeck installations.

Of the other materials commonly used, vinyl often becomes brittle and may shrink with age.

Galvanized and Galvalume treated steel roofing and soffit panels adapted for underdeck use are formed similarly to a tongue and groove floor. If inspection, repair or cleanout is required, the last panel installed must be removed and each panel in turn removed until the area needing service is reached.

Treated steel is rust resistant only on uncut surfaces. Cut edges will rust unless retreated.

Magnolia's panels are designed so that any panel may be removed without disturbing adjacent panels, making service and clean out practical and efficient.

Another material used to waterproof an underdeck area is rubber-like sheeting. It is draped over the top of the deck joists before the deck's surface is attached. The underdeck ceiling area is then covered with beadboard, drywall or another surface. If a leak or stoppage occurs there is no alternative to removing the deck surface, or the finished ceiling below to effect a repair

I am looking for an under deck ceiling I can install myself. Is this possible with your system?

We encourage homeowners and contractors to install our kits. Information about our kits is available at Magnolia's Kits Page, or our Home Page. We offer consultation with one of our installation experts on the Magnolia System and how it applies to your particular situation. Once the project is begun this support will be available throughout the installation. Our phone support(770 309 3999) is of course available seven days a week with extended hours. Our Installation video is available online here. Return to FAQ

Can I have the system installed?

Yes. Many times we can refer you to a contractor in your area, or we will train a contractor of your choice.

We manufacture custom underdeck ceiling kits. Our systems have been successfully installed by contractors who have been trained in our techniques. The training is free of charge to all. We have a comprehensive instructional video on our site, and a DVD with the same content is supplied to each new kit builder. Each kit is shipped with a printed instruction manual. The system is designed to be installed by anyone with basic construction skills and a few ordinary tools.

We offer comprehensive, in person training at our manufacturing facility, and as of this writing are developing the capability to broadcast this training live over the Web.

How much waste material will I be paying for?

Each system is custom built, therefore you do not pay for extra material you do not use. Return to FAQ

I have heard about corrosion resulting from aluminum contacting pressure treated wood. Is this a problem with the Magnolia system?

No. It is not a problem if the installer follows Magnolia's Installation Instuctions. Click here for Installation Video.

How long does a typical installation take?

A simple rectangular deck will take an experienced installer and a helper one to two working days to install. Return to FAQ

What can prolong the installation time?

For the kit installer the short answer is, inexperience. We include complete installation instructions and DVD with each kit. We hope the installer will take the time to refer to them often and follow them carefully. The basics are covered in our installation summary elsewhere on this site. Our telephone support (770 309 3999)can clarify any puzzling issues. Wiring, bay windows, cantilevers and other non-rectangular shapes will take more time, even for experienced installers. Return to FAQ

Do under deck ceilings require maintenance?

Periodic inspection should be done every year or two to check for the possibility of accumulated leaf and debris buildup. We make every effort in our under deck's design and installation to ensure a trouble free experience, but variations in rainfall, the surrounding vegetation and the construction of the deck can all lead to accumulation of debris on an underdeck.

Our underdeck is a free span system, laid out so that the pitch of the panels is built true without structural parts of he system laying across the flow of the panels.  There is no chance for pooling of water on its way to the downspout. But, over time, there is the possibility that the deck structure may sag slightly, leading to standing water on the ceiling panels.

The exclusive brackets that help support our panels are adjustable to flatten the bottom of the ceiling panel and so send pools of water on to the downspout.

Magnolia is the first underdeck manufacturer to facilitate inspection by designing a system that allows for easy removal of a single panel for ease of inspection or the addition. of new features such as recessed lights or fan mounts. Return to FAQ

Does my underdeck ceiling need to be ventilated?

There is often mold buildup in the enclosed space in an underdeck. there is also the possibility that prolonged moisture will hasten decay of newer "above ground" pressure treated lumber. Because of this we are now offering power ventilation as an option with our underdeck systems. Early evidence is showing a reduced accumulation of leaves and debris as well, thus reducing the need for cleanout. A more in-depth explanation of this question is available here. Return to FAQ

Suppose I  need to get into the space above the ceiling, how difficult is that?

Any panel that is not attached to a ceiling fan, or other through fixture can be easily removed.

I have a cantilevered deck. How does the Magnolia system accommodate this?

We treat the area under a cantilever as an entirely separate system. It will have its own ceiling panels, support and drainage systems. Return to FAQ

How much will the Magnolia system reduce my head room?

The ceiling requires a minimum of 2 1/4 inches clearance below the lowest point on the deck above. Our system slopes in two directions. The panels drop 1/8 “ per foot. The pitch from the high point of the gutter to the outlet is an additional 1/16 “ per foot.
This means that a typical 10 by 20 deck will drop 1 1/4 inches in the direction of the ceiling panels and an additional 1 1/4 inches along the gutter toward the downspout.
The high end of the gutter is therefore 3 1/2" below the joists. and 4 3/4" on the outlet end of the gutter If there is 10 feet of headroom it will be reduced to 9 feet 8 1/2 inches on the high side to 9 feet 7 1/4 inches at the corner next to the downspout. Return to FAQ

Will stains or paint applied to my deck damage the Magnolia system?

No. Of the paints or stains we have investigated, most are harmless to aluminum. However, it is very important to read the paint or stain manufacturers literature, or consult with your paint dealer to confirm this. Return to FAQ

How does the Magnolia System differ from similar products?

Other systems may match some of our advantages. None can offer the suite of features that make the Magnolia system unique.
We offer a smooth, flat, finished appearance. We offer removable panels with adjustable panel supports which keep the pitch of the panels true over the years.

All major components are aluminum. It is lightweight, strong, rust free and will not deteriorate or become brittle with exposure to the elements.
Both the ceiling panels and gutter are slanted to provide drainage.
All the major components are manufactured by Magnolia. We have total control over the quality of the product placed in your home.
The Magnolia system is a free span design. There is no obstruction to the flow of water from the deck above to the gutter.
No flashing is required on most installations.
The system is designed to be installed by anyone with basic construction experience, and a few ordinary tools.
We offer complete support during the installation process. This support includes consultation with an experienced installer seven days a week. This is geared to your particular situation. Decks are too variable for a cookie cutter solution.
Any one, or a few of these advantages are offered by other systems. No other system can match this suite of features. Return to FAQ

Can ceiling fans and swings be attached to the Magnolia system?

Definitely. Ceiling fans, porch swings, sling chairs and beds are routinely mounted to our system. Return to FAQ

I live in a cold climate. Will temperature extremes affect the Magnolia system?

In the last fifteen years we have shipped kits to all across the continental U.S. Our kits have been installed  where temperatures commonly range from below zero to 100º plus. There have been no reported issues with performance under these weather extremes.

Expansion and Contraction: The ceiling panels are fixed to the gutter on one end, while the other end is supported by the wall channels, but not fastened, so there is no resistance to expansion and contraction due to temperature fluctuations.  Return to FAQ
