LAGS AND RAFTERS:
For maximum strength, you want your mounting rail (2) lags (2A) to go into rafters. After locating the best area for
the collector, “sound out” the roof for the rafters with a hammer and mark the rafter centers with chalk. On thick roofs,
such as shake, you may need to drill a small hole from the underside of the roof next to the rafter to locate it from the
roof and use measurements from thereon. On thin composition roofs, a good stud finder can be very helpful in finding
the center of the studs.
It is best to “run the lag into the roof once, remove it, then fill the hole with caulk and run the lag with washer
back in and tighten.
Some installers like to pre-drill the hole with a smaller bit than the lag to prevent cracking shake shingles.
GETTING THE COLLECTOR ONTO THE
ROOF:
Use wisdom, when pulling collectors up onto the roof,
have the collector at a good angle to the roof (out at the
bottom). Protecting the gutter with a heavy cloth may be
a good idea. Do not lean over the edge of the roof at all,
simply pull and leverage the collector up onto the roof.
The assembled collector is very sturdy but avoid
“twisting” it.
If the edge of the roof is over 10 feet from the ground, the
bottom of the collector may be placed on a sturdy object
or someone may be needed to boost the collector up to
you.
On two story houses we strongly recommend two
people for safety.
A sling can be made with sturdy rope going all the way
around the bottom of the collector with shorter pieces
going around the collector to secure the rope in place. Be
sure to secure it very well and always have a secure safety
rope you can grab onto. Have the second person push
the collector up the ladder while it is pulled at the top.
