Part 5 - Roof / Wall Mounting Suggestions

Working on the roof is extremely dangerous. Plan the installation

carefully such that a safe distance from the edge can be maintained.

Sure footing is also required. Be sure to wear sturdy, rubber soled

shoes. NO SANDALS OR FLIP FLOPS. Harnessing equipment for fall

prevention is mandatory.
Be sure that the roof is dry before beginning installation. Be sure

that any ladders are set firmly against the side of the building and

mounted properly. Have someone hold the ladder for you while you

climb.
Be aware of any electric or water lines before drilling into the roof.

Plan the installation accordingly.

The following details suggested roof attachment methods:

J Bolt Penetration

Lag Bolt Penetration

Threaded Bolt Penetration

A. Roof Mounting

In order to meet strength requirements in areas with winds up to 130

mph and category “D” exposure, collectors should be mounted into

roof studs using lag threaded bolts or J bolts. Any other installation

format should be approved by a structural engineer.

Example of Roof Flashing

Failure to follow this information could result in property damage,

serious personal injury, or death.

Ensure the roof surface is solid and able to withstand in excess of

330 lbs of pull force that may be encountered during high winds.

Consult a structural engineer if in doubt. Failure to do so could

result in property damage, severe personal injury, or death.

B. Wall Mounting

Wall attachment methods depend largely on wall material. For brick

or concrete walls, secure collector feet with stainless steel expansion

bolts. For wood or synthetic boarding, stainless steel screws that can

penetrate into the wall framework may be suitable for mounting. If

the strength of these screws is a concern, use bolts that run directly

through the wood with a large washer or metal plate positioned

before the nut.

Consider possible shading from eaves, particularly in the summer.

Strategic shading may be included in system design to minimize

summer heat output. Another advantage of installing under an eave

overhang is to minimize snow buildup on the collector in areas with

regular snowfall.

If installing on a wall such that the collector is above a walkway,

please consider snow and where it will collect when it slides off the

collector.

When attaching to the roof surface, it is important to ensure proper

sealing to prevent water penetration. It is also important to consider

the building structure and roof construction type to ensure the

structure is adequate for the collector’s weight and can withstand

wind loads as determined by local codes. For commercial buildings,

it is especially recommended to consult a structural engineer.

When installing a collector that will be raised and not flush to the

roof, the increase in wind stress at the mounting points must be

considered. Consult local wind load requirements.

Use larger stainless steel lag bolts to fasten the collector feet to a flat

roof. If standing water may gather on the roof around the collector,

ensure that all mounting and plumbing holes are thoroughly sealed

and waterproofed.
