Solar Roofs Fireball 20014, Installation Manual

FLASHING IN UNDER SHINGLES 

For Tile and other roofs, consult with the Factory. 
For Composition and Cedar Shake Installation: 

ACRSI supplies two special roof “Flashings” which 
are used to make a waterproof seal for the solar 
collector feed and return lines.  These flashings easily 
slip under a composition or shake shingle with 
minimum cutting.   

The tubing hole is large enough for the 1/2” od copper 

pipe to easily slip through and the small space left can 
be easily sealed with caulk and further covered with 
insulation.  The base of the flashing can flex and be 
moved in different directions.   

The 6” aluminum base is usually large enough to 
make a watertight seal and can easily be flashed over 
by a larger aluminum sheet when needed.  It is 
recommended that a 1 ½” hole be drilled for the 
tubing hole.

 “Roof Boot” Flashing and Waterproofing Details 

The 2 aluminum flashings supplied with the system 
are easily installed but require careful alignment to 
assure a good fit. It is recommended that up to a 1½ “ 
hole be drilled to give “working room” when 
installing the roof boot. 

Spacers are included with 

flush kits to make boot installation easier. Pre -fit 
roof connections prior to drilling (see Section 8, top 
and bottom connections). 

NOTE: sound out your roof to be sure no rafters 
are under where holes will need to be drilled! 

Preposition the roof boot where it will go when the 
pipes are connected to the compression 90 in its final 

“out” position.  Mark the center of the hole, remove 
the fitting and place out of the way.  Using a 1 ½” 
hole saw or paddle bit, drill the hole.  Carefully pry up 
the shingle and slip the Roof Boot under the shingle 
so water will freely flow over the roof boot.    

If needed, add aluminum flashing to assure a 
watertight installation (especially needed with Cedar 
Shake).  Caulk the sides as needed and it is good to 
put two roofing nails in the bottom of the boot to 
secure it AFTER the pipes are installed and fully 
secured.

Note that Roof Boot is UNDER the shingles at the top and most of the sides so water flows over the top.  
The shingle is cut down from where the hole is drilled.

Drill a 1 ½” hole 1 ½” in and centered 

2” below the edge of the collector. 

Slip flashing under shingles. 

Use a “lifting Tool” with smooth edges to go 

under and lift the shingle without cutting it. 

Lift shingles before installing collectors. 

Properly placed, the feed line is right 

above the flashing tube hole. 

The edge of the collector is 1 ½” above 

the lower edge of the rails.
