Semi-intensive green roofs are a great compromise if you wish for a more insulated green roof, but don’t want to go with an intensive system. Semi-intensive roofs are 6″ to 10″ deep and may also have a reservoir layer, though this often is a choice contractors will make on an individual basis. Semi-intensive green roofs are the second most common type, but naturally offer greater advantages and more versatility if you plan on planting your roof with larger greenery. Perhaps not an advantage for a residential home, commercial buildings with a green roof can be a huge morale boost for office settings. While a typical roof is hardly a space to relax, a green roof can have seating added to it and become accessible to building tenants. Adding more vegetation in an urban setting has a number of benefits on it’s own, let alone as a quiet, recreational place for people.
And finally, a ground mount system does not require penetrations in the roof. Ground mounts also benefit from having more airflow to cool the solar panels. There is a direct correlation between cooler temperatures and higher efficiency. When the panels are cooled by better airflow underneath, efficiency and electricity production goes up. Panels on a roof are generally inches from the surface, meaning that there isn’t much room for circulation to cool the panels. The placement of a ground mount system also makes them much easier to access for maintenance or cleaning when necessary.
Therefore, the RoofSafe® Cable System has the same level of quality as other fall protection systems for less money. Dampers and controls allow for outside air to be used for cooling when outdoor temperatures are moderate. A rooftop photovoltaic power station (either on-grid or off-grid) can be used in conjunction with other power components like diesel generators, wind turbines, batteries etc. These solar hybrid power systems may be capable of providing a continuous source of power. Due to economies of scale, industrial-sized ground-mounted solar systems produce power at half the cost (2c/kWh) of small roof-mounted systems (4c/kWh).
In an inverted membrane system, the coventional membrane arrangement is invereted or turned upside down. Inverted roof membrance assembly systems are used in applications where the membrane requires protection from site-specific hazards. These systems are typically applied in conditions where there is extensive roof traffic or to protect from excessive weather conditions such as multiple hail events. IRMA roofs protect the membrane from ultraviolet degradation and constant temperature changes.
After installation of the membrane, a batten bar is placed over the membrane and screwed to the deck. The stone in the center of the photograph shattered into several sharp pieces after installation on a ballasted single-ply. Installation of a stone-protection over the membrane would avoid punctures and sharp fragments such as these. If crushed aggregate is specified, a stone-protection mat between the membrane and aggregate should be specified to avoid puncturing the membrane.
Advocates counter that the higher the concentration of rooftop solar systems in a neighborhood, the less a utility has to spend on distribution to shore up grid reliability. But the math only works in places with so-called “net metering” laws, which require utilities to buy the electricity rooftop panels generate at prices far above what they pay for centralized power. Rooftop installers like SolarCity enjoyed rapid growth thanks in part to a marketing message that peddles the romance and freedom of generating emissions-free power at home. And, for homeowners in states with favorable policies, rooftop panels can be a good investment, ultimately offering savings. Generating power from residential rooftop panels is far more expensive, ranging from $184 to $300 a MWh before subsidies, the report said. The success of large-scale solar has raised questions about the wisdom of continuing incentives for rooftop installations, which remain far more expensive than most other forms of electricity.
A low-maintenance and environmentally safe solution ideal for surfacing playground and pet areas. GRO wood decking and tile pavers are designed to interchangeable, so you can spice things up a little. GRO Adjustable Deck Pedestals, with large diameter heads and bases, create a level and ultra-stable pedestrian surface for all paver types and sizes.
They were professional, fair with their pricing, and respectful of our property throughout the whole process. I called CRS after sustaining roof damage due to a fallen tree limb. The office staff was kind and understanding and were able to get a crew out to assess the damage very quickly. I ultimately chose to go with CRS to make the repair and am very happy with the work that was done. Over 40 years servicing commercial and residential properties across New Jersey.
