Basic Home Roof Installation Guide & Information€¦ · Using liner panel screws or flat roofing...

Step 1 - Install a moisture barrier/underlayment over the entire roof.

Underlayment can be applied directly over shin-

gles, or the existing roofing can be removed

to expose the plywood sheathing.

If applying over shingles, once the under-

layment is applied, install purlins or fur-

ring strips over the top of the underlay-

ment to use as screw points for the metal

roof.

American Roofing Products recommends a

synthetic felt underlayment.

Step 2 - If desired, install fascia trim along the gable edges and/or the eaves.

Gab

le

Eave

Using liner panel screws or flat

roofing nails will keep the fas-

cia trim profile flat to the gable

or eave edges.

Fascia

Step 3 - Install drip edge over all the eaves of the roof.

Eave

Drip Edge

Drip edge will overlap

the fascia trim as

shown.

Use low profile screws

or flat roofing nails to

secure the drip edge to

the sheathing or

purlin.

Sidewall trim is installed

under lapped on the building’s siding.

The hemmed side is secured through a

flat area on the panel.

Butyl (tacky) tape is applied to seal the panel to the trim.

Step 4 - Install W valley trim where roof seams meet. W Valley

Install from the eave upward to the ridge, over-

lapping as necessary. Apply two rows of Solar

Seal or butyl tape to minimum 6” overlap ar-

eas.

Use valley seal tape to seal the space between

the W valley and the panel on top of it. Panel

should be 4” from the V in they valley. Screws

that secure both the valley trim and panel should

be placed behind the valley seal tap.

Step 5 - Begin to apply AmeriRib panels.

Ensure the initial panel is square before secur-

ing.

Install the roofing over the drip edge and val-

leys already installed.

See our previous diagram for proper screw

placement.

Ensure that chalk lines used to line up screws

holes are cleaned off the roof after installation.

Step 6 - Install sidewall trim. Sidewall


Butyl Tape

Similar to sidewall, endwall trim is in-

stalled under lapped on the building’s

siding. The hemmed side will shed wa-

ter on the sloped roof. Outside closures

prevent blowback.

Longer screws are needed to attach, generally

2”. Secure the endwall near the hem, through the major ribs and outside closure and into

the sheathing or purlin.

Step 9 - Install ridge caps.

Gable/rake trim overlaps the metal on the

gable edges of the roof.

The top side overlaps the panel and butyl

(tacky) tape should be used to seal the gap.

Step 7 - Install end wall trim.

Endwall

Step 8 - Install gable/rake trim.


Butyl Tape

Gable/Rake

Ridge caps are installed to seal the roof at

it’s peak.

Vented closures allow air to vent prop-

erly from ridge vents.

Longer screws are needed to attach ridge cap, generally 2”. Secure the ridge cap through the

flat near the hem, through the major ribs and vented closure and into the sheathing or purlin.

● Install underlayment—synthetic felt and/or house wrap.

● Attach rat guard/base guard to the base of the outside walls.

Level and secure the rat guard to the baseboard of the building.

AmeriRib panel should rest on the trim as shown.

● Windows and doors should be wrapped with J channel and drip

flashing. Note that drip flashing should only be used

above doors and windows. The exception to this is

cannonball track cover, which should replace drip

flashing over sliding doors.

● Using shears, cut paneling to fit around windows and doors. Install side paneling. Ensure the first panel

on each wall is square before securing and adding additional panel. Use metal self tapping screws if apply-

ing to metal structure. The panel should rest/drain on the rat guard, on

top of drip flashing/cannonball track cover, and securely into the J

Channel.

● In addition to the above, for wainscoting or panel separation, use Z

Flashing to separate and properly flash between the panels.

● Inside building corners are sealed with inside corner trim pieces.

● Outside building corners are sealed with outside corner trim pieces.

● Larger doors can be trimmed out with Overhead Door Trim and Door Post Trim

● Install door hardware. Generally, the door assembly consists of

round track, a trolley that attaches to the door and rolls on the track,

latches, door stops, and side and bottom rails.
