Installation Guide
•  Redirect Water – Water is the enemy of most structures. 
Take care to redirect water from your building whenever 
possible. Rain water runo from other structures and 
misdirected irrigation systems can damage your 
TUFF SHED building, and is not covered by warranty.
•  Re-paint Regularly – Painting is one of the easiest ways 
to protect the exterior wood surfaces of a TUFF SHED 
building. Your building’s warranty coverage requires 
that the building be re-painted every ve years.  
We recommend using high quality materials like 
Glidden Paints.

 10 APPEARANCE OF MATERIALS
Wondering about the appearance of a certain feature 
of your TUFF SHED building?
This information can help you better understand why 
some components look the way they do.
Displays
Display buildings are sold in “as is” condition, which 
can vary, ranging from minor blemishes like faded 
paint to more signicant issues such as damaged 
trim, missing shingles, and dented or bent oor joists.
Roong Nails
•  It’s not a mistake that nails are poking through the roof 
on the inside of your building. This is necessary due to 
building codes requiring shingle nails to “pierce the roof 
decking material” and does not aect the performance of 
the roof.
Galvanized Steel Floor Joists
•  Most of our sheds include 16-gauge, hot-dipped 
galvanized steel oor joists, which are designed to be 
placed directly on any rm, level surface.
•  White “Chalking” on the Steel – This appearance is normal 
and does not aect the performance of the steel or the 
40-year industry-rating on the material.
•  Exposed Steel – These joists are designed to withstand 
the elements and are exposed after installation. 
Some customers prefer to cover the steel with “skirting” 
made from siding. While we can add a skirting, we don’t 
recommend it, since wood siding material contacting the 
ground can wick up moisture into the building.
•  Small Rectangular Holes in the Steel – During production, 
small vent holes are punched into the steel. These holes 
allow for airow beneath the building. Snap-in screen 
vents are available as an inexpensive upgrade.
Lumber
•  We use dimensional lumber for wall and roof framing that 
has been dried, then stored in a controlled environment 
(our factories) prior to installation. It is unlikely that this 
wood will have a uniform appearance, and may have 
blemishes or “waning and knots”. This is normal and will 
not aect the structural integrity of the building.
Weathertight or Airtight
•  We strive to make the building weathertight. But they are 
not airtight. Air and mice can inltrate your building as 
they can your home.
