Metro recommends installers of MetroSHINGLE products use a
Metro Cutter, and have completed a 'SMART-Start On Site installer
Training Orientation Program’ (located at http://www.metroroofs.com/
SmartStartTraining.cfm) for each profile installed. Metro does not
consider its products to be “do-it-yourself’ (D.I.Y) mainly due to
specialized cutting & bending tools used during installation.

A MetroSHINGLE roof starts with perimeter metal
& valley flashings, followed by field panels; installed
from right to left, one course at a time, across the
roof and up towards the ridge. Panels are measured
and cut to fit areas around the perimeter of the roof;
i.e. rakes, ridges, hips, & valleys. Trim caps are then
installed, followed by an overall quality review of the roof.

Front Downturn Nose: 3/8” (9.52mm)
Back Up stand: 3/8” (9.52mm)
Back Horizontal Flange: 3/4” (20mm)
Materials:
Metro panels are produced from Aluminum-zinc alloy
coated steel complying with ASTM A792.
Packing and Storage:
Fasteners:
All fasteners (Nails or Screws) used on a Metro roof for
panels, trim caps and accessory items shall meet or
ASTM B-117, (1,000-hr minimum Salt Spray Corrosion
Resistance).
For HVHZ (High Velocity Hurricane Zone) areas refer to
local code requirements and/or Metro website (www.
metroroofs.com) for details.
Sealant/Caulking
Only exterior grade urethane or (non-acidic) caulking
should be used for sealant.
Testing:
Metro panels have been tested in accordance with
local, national & international building codes. Testing
has been conducted to evaluate fire, wind, penetration,
water infiltration, and durability resistance. Information
regarding specific tests and approvals can be obtained
from Metro Roof Products.
Ventilation:
Ensure proper attic ventilation as prescribed per local
codes. Either Smart Vents or Ridge venting can be
installed to achieve adequate ventilation.
Warranty:
This limited warranty is transferable and does not cover
damage due to improper handling or installation.
Dissimilar Metals:
To avoid adverse corrosion effects caused
by dissimilar metals, COPPER and LEAD
products and accessories. (refer to Metro SMARTbrief
#02004)
Finish coating:
Unless local conditions require otherwise, either one
or equivalent should be used with Metro panels.

an area free from moisture. Refer to pallet storage
warning information for more details.

Minor scuffing of the Metro stone-coated finish can be
repaired with a Metro Touch-Up Kit. Use the Metro base-
-coat acrylic supplied in the kit (not caulking) for repairs.
Unfinished flashing material can be painted with durable
acrylic aerosol paints. Colored aerosol paints should
never be used as 'touch-up' on stone-coated products.
Front-Interlock
MetroSHINGLE panels are CONCEALED fastened.
They incorporate a rear fastening flange. Panels
interlock from top to bottom at the "Pittsburg-Lock"
formed sections on the panels. The interlocking
sections create a weather barrier. The dimensions
of this pannel are as follows:

SOLAR SYSTEM FLASHING MOUNT:
As round pipe is often used to support solar systems, the details above can be used to flash the supporting
solar members.
New vent jacks are installed at roof penetrations. Panels are neatly cut around protrusions as required and
installed over vent flashings.
After first sealing the panel, the vent flashing is
positioned over protrusion.
Stitch screws are used to secure the flashing to the
shingle panel. Care is taken to locate the screws over
higher ribbed panel sections, or through sealant.
Then cut the Back-
-Interlock and flatten.

CENTER CAP
To create a center cap, simply cut-off
the interlock flange and fold-over the
cut edge so it resembles the front

Position and fasten the center cap
at the desired center point of the ridge
after installing the caps from either end
of the roof.
FIRST HIP CAPS
The first installed Trim Cap is cut and hemmed to lock over the
