The average industry-standard solar panels weigh between 33 pounds and 55 pounds. When you factor in that many solar panel systems have over 10 solar panels, the total weight can stack up fast.
One of the critical aspects of deciding if solar works best for your household is seeing if your roof is capable of meeting the solar challenge. Read on to see if your roof has what it takes.
Roof Load-Bearing Capabilities
One of a homeowner’s worst nightmares is roof collapse. The last thing that you want after spending all that money on a solar panel installation is to have the entire system come crashing down through your bedroom ceiling!
The average weight-bearing capabilities of a normal shingled or wood roof are 15 pounds per square foot. This increases by about ten pounds to 27 pounds per square foot for roofs made out of metal or clay.
These statistics are for the “dead-load” capabilities of a roof which means a load that is being permanently supported by the roof. They also only apply to structurally sound roofs.
Most traditional (non-metal) roofs have a lifespan of around 20 years. If your roof is due for a tune-up or replacement, it may be best to call a professional roofer before any sort of solar installation consultation.
Only they can tell you if your roof is structurally sound enough to bear the additional weight of solar panels.
Other Considerations for a Roof With Solar Panels
In addition to the load-bearing capabilities of your roof, there are a couple of other factors that you may want to take into consideration when deciding about a solar panel installation.
The first is how much sunlight your roof gets. If any trees are blocking your roof you may need to remove them to alleviate any shading.
This is particularly important for any trees that threaten your roof with storm damage. If your roof is struck by a tree, your new solar system may be damaged as well.
In the northern hemisphere, you want a south-facing roof. This aspect gets the most sunlight. If your roof faces any other direction, it may not be the best place for solar panels.
Also, your roof’s total area will determine the number of solar panels that can be installed. If your building possesses a small roof, it may not be the best option. The same goes for a flat roof, as solar panels are best installed on angled roofs.
Find a company that specializes in solar panel installation in your area. Only they can conduct a proper site assessment and let you know if your roof is ready to meet the solar challenge. If not, a ground-mounted system may be a better option.
Is Your Roof Ready?
Only a team of professionals can tell you if your roof is ready for solar panels. Call a professional roofer and get an assessment. Then call a reputable solar panel installation company and get an estimate.
