Protect the Roof from Stress

Where the roof changes plane or terminates at a wall, metal edge, curb or other obstruction, it has the potential to be stressed. The vertical portion of the flashings is especially prone to damage by people on the roof. Ropes hung over the side of the roof for boson chairs or window washer fall protection can abrade the flashing, causing tears and punctures. Unprotected roofing between access doors and ladders and mechanical equipment is subject to premature wear from foot traffic. Dropped tools and debris left behind can cause punctures and tears in the membrane. Simply put, you roof can go through a lot of abuse.

The simplest and best way to protect a roof from this abuse is to limit the traffic on it. If roof access can’t be limited, such as the need to change AC filters, the next best solution is to provide protection at those areas that are the most vulnerable — around the HVAC equipment and the pathways to them. Adding walk pads around each unit will help to minimize the damage to the membrane from excessive wear. When swing stages or boson chairs are used, the contractor should be required to provide protection for the parapet walls. Plywood can be used to protect the field of the roof by spreading out the load on the membrane and by providing a physical barrier to flashing damage.

In asphalt-based roofing systems where the deck is not supported by the walls and the two are allowed to move freely, the flashings can be subject to stresses caused by differential movement between the deck and the parapet walls. The result will be diagonal wrinkles in the flashings that will eventually crack due to material fatigue. This is less a problem with single-ply membranes because their greater flexibility allows them to stretch and relax better with the building movement.

Unfortunately, once the roof is installed, there is no way to protect it from diagonal wrinkling. The only way to minimize damage from the building movement is by proper design of the flashings or by understanding the demands of the construction and to choose a different type of system.

What can you do to stay ahead of roof stress? Make sure all HVAC units and pathways have protective walkway pads. Limit access to the roof as much as possible and utilize your resources at RAMCON to ensure proper design that meets the buildings requirements.

Roof Penetrations Can Be the Weak Link

Every roof has them, and many of us know the headaches they can cause. We’re talking about roof penetrations (vent pipes, drains, pitch pockets), which are often a roof’s weak link. With single-ply membranes, this means a boot or field-formed membrane that is adhered or welded to the roof membrane with a draw band — a metal collar that fits around the protrusion — and sealant at the top. It’s important to ensure that the draw band is tightly attached but does not cut into the flashing and that the sealant at the top is installed with no voids or unadhered sections. The membrane flashings on single ply roofs at pipes and other penetrations, no matter what the material used, are usually the first items on the roof to deteriorate from age and abuse, so careful attention should be paid to the condition of these flashings.

A modified-bitumen or asphalt roof will often use pitch pockets with pourable sealers. Alternatives are goosenecks and perma-flash. Pitch pockets are the most common, with a weak link occurring when the pourable sealer deteriorates and cracks over time. This is accelerated by any movement in the penetration, causing a separation between the penetration and the sealant. Watching for signs of cracks in the sealant in the pitch pocket and around the penetration. Re-sealing these areas routinely will help keep the roof watertight. Your RAMCON technician can ensure that the sealer is filled to the pitch pocket top to keep the penetration from holding water.

With pitch pockets, there can be additional problems. It’s vital that the sealant applied be appropriate for the roofing system. If the sealer used is asphalt or roofing cement, it will shrink over time, causing cracks within the sealer itself or causing it to pull away from the penetration. This leaves a direct path for water to enter the roof. Regular maintenance of the pitch pans includes crowning the sealer to shed water away from the penetration. RAMCON always utilizes stainless steel pitch pockets on our roofing systems, but many contractors do not. If another contractor used galvanized pitch pockets, checking the pan for rust is essential. Wherever the rusting occurs, there will eventually be a hole.

Metal penetration flashings are dependent upon compression tape and elastomeric sealants to keep the penetration watertight. The sealants should be examined on a regular basis and replaced when they begin to harden and crack. With both the pitch pockets and the metal flashings, the membrane stripping between the flanges of the metal and the roof should be adhered tightly to both the metal and the roof for an adequate seal.

If you have problems on your roof, there is a good chance it is directed from roof penetrations. Trust the professionals at RAMCON to install these correctly and fix any problems the right way.

Types of Solar Panels

Monocyrstalline
Generally considered the workhorses of the solar power market, these are made from cells created by cutting thin slices from single crystal silicon block and are higher in efficiency, but also higher in cost per watt. These are easily identifiable, made up of uniformly stacked rounded cells.  Because they’re made from just one crystal, not multiple crystals fused together, the process of making them is one of the most complex and costly ones around.

 

 

Polycrystalline
These are made from cells created by cutting thin slices from polycrystal silicon block and are slightly lower in efficiency, but also lower in cost per watt. Polycyrstal silicon is the “chicken nugget” of silicon, made by combining many individual crystals. They are easy to spot because they have an uneven color, usually blue.

 


Thin Film
These are made by depositing a thin layer of very finely powdered silicon (amorphous silicon) or other photovoltaic material, on a substrate. While lower in efficiency that crystalline cells, they are considerably cheaper per watt. The downside is that they take up more space per watt. They are perfect for roof mounted systems as they are incredibly strong, have superb wind uplift and produce power even in undesirable conditions.

Facts About Solar Energy


Sun Related Facts About Solar Energy
  • Sunlight travels to the earth in approximately 8 minutes from 93,000,000 miles away, at 186,282 miles per second.
  • The sun is also the main source of non-renewable fossil fuels (coal, gas and petroleum), which began life as plants or animals whose energy came from the sun millions of year ago.
  • Solar energy is responsible for weather patterns and ocean currents.
  • Clouds, pollution and wind can prevent the sun’s rays from reaching the earth.

Other Interesting Facts About Solar Energy

Incentives Make Solar Energy More Affordable Than Ever

The combination of government and utility incentives can drive down the cost of your solar installation by up to 70%! Federal, State, and Local governments, along with utilities, are pitching in to lower the cost of your solar panels because solar is a great investment for them as well as for you.

Federal Rebate
The Federal rebate is very straightforward. It is 30% off your installation price. It’s a simple one page form that attaches to your Federal tax return and you will get your money as a tax rebate.

Florida Incentives
As part of the 2006 Florida Energy Act, the Solar Energy Systems Incentives Program offers rebates for individuals or businesses to purchase solar photovoltaic systems. Solar photovoltaic systems are eligible for a $4/watt rebate, capped at $100,000 for businesses. In addition, In May 2005, a law was passed (HB 805) that permanently made photovoltaic panels exempt from Florida Sales Tax.

Utility Credits
Florida encourages its utility companies to utilize green technologies, specifically solar. As such, the state offers a $0.01/kWh credit to power companies that use renewable energy. The utility achieves this by providing incentives to you to install photovoltaic systems, which are becoming more generous. It’s a win-win-win situation; you get money from the utility for putting up solar panels, the utilities don’t need to become experts in adding solar to roofs, and the state gets more solar installations.

Net Metering
As of July 1, 2009, all utilities in the Florida, whether investor owned or owned by the municipality now have to credit your solar power dollar for dollar.  That means any excess energy your panels produce gets sold to your local utility, and then you get to buy that power back at the same price.
