This roof type consists of a series of flat, broad metal panels that are crimped together to form a continuous, concealed join. There is a vertical leg between each one this is the raised seam.Not only is this type of roof lightweight and durable, when installed in sequence with the recommended underlayment, it is also watertight.

It’s almost as if metal standing seam roofs are specifically designed with solar panels in mind.The installer attaches a series of high-strength aluminum clamps to the vertical legs with a single bolt. The mounting rail secures into place with no need to drill any holes into the roof. With no perforations in the metal, it remains watertight people with asphalt shingles have to check and maintain theirs annually.Installing a solar array on a seamed roof is simpler and far-less labor-intensive, and therefore, more affordable.The clamps and bolts are often covered by several-year warranties, although most owners claim they outlive their solar panels.Tile Roofs

Solar Panels On A Standing Seam Metal Roof

Metal roofing panels are very compatible with solar panels.We recommend they be used with standing seam panels. This is because these roofing panels dont require any holes to be made in the roof when securing the solar panels.

A standing seam panel features vertical ribs at the panel edges that a solar mounting system can attach to without the need for making penetrations. Any penetrations in a roofs surface can compromise its weathertightness and leave the roof susceptible to leaking. Standing seam is not only the most compatible among metal roofing panels, but one of the most solar panel compatible roofs in general.

If you have a corrugated metal roof, solar panels can still be attached with mounting brackets. However, the brackets will be attached directly to the panels with fasteners that will penetrate the corrugated metal panels.

Can Metal Roofs Handle The Weight Of Solar Panels

Metal roofs are strong and durable, and they can certainly support the weight of solar panels. In fact, many metal roofs are specifically designed to accommodate solar panel installation.

It is important to make sure that the roof is properly reinforced before installation begins. Otherwise, the added weight could put undue stress on the roof and lead to damage over time.

With proper reinforcement, though, a metal roof can provide a stable and long-lasting foundation for solar panels.

If you have any doubts at all It is very important to check with the manufacturer to make sure that your particular roof can support the weight of solar panels.

Instructions For Installing Solar Panels On Roofs

Here are the pro tips when mounting solar panel systems on shingle roofs:

Step 1: Lay out the installation materials you need.

Make sure that all the materials necessary for installation are nearby. You surely wouldnt want to go from the roof and back repeatedly.

Step 2: Determine where the stanchions go.

Find the roof rafters with the aid of a stud finder or your homes blueprint. These will help you figure out the correct placement of the stanchions. Position the stanchions at least 4 feet apart.

Step 3: Fasten the screws to the roof.

When fastening the screws to the roof, utilize a drill to create holes in the rafters.

Step 4: Tightly put the screws in the holes and secure them.

It would help if you tightly secured the lower and upper aluminum rails to the stanchions. Utilize bolts to do this. Since optimal tightness is required, utilize an impact driver to achieve this.

Afterward, make sure that you seal the screws tightly to maintain the thermal envelope of your home. Substantially, thermoseal roofing is the most excellent way to execute this.

This approach will help keep an incredibly tight lock on your roof and prevent any elements from getting inside. Leakage is less likely to emerge if the stanchions are correctly installed.

Step 5: Gauge the distance from the rails.

Gauge the distance from the rails when installing solar panels. Put a measuring tape diagonally from the top of one rail to the bottom of the rail situated directly across from it.

If you want to put solar on a metal roof, these are the top five things to think about:

  • Solar panels on a metal roof will require specific equipment and process to install.
  • Thin-film panels and regular solar panels may both be installed on solar metal roofs.
  • Metal roofs are long-lasting and can outlast solar panels.
  • Solar panels can boost a metal roofs cooling capabilities.
  • A residence with metal roofing and solar panels is more environmentally friendly.

1. Different process to install solar panels on a metal roof.

Typically, your solar installer will drill a hole on your roof so that the mounting for your solar panels can be attached. This is a major source of anxiety for many homeowners thinking about going solar since an incorrectly placed solar panel installation can create leaks or other roof difficulties. Most qualified solar contractors provide workmanship and roof warranties to ensure their consumers that the installation will go smoothly.

However, if you have a metal roof, your solar installer will most likely not need to create any holes in your roof at all, which essentially eliminates the risk of future problems. There are a few other mounting solutions that make it easier to put solar on a metal roof:

2. Thin-film panels can be used alongside regular PV panels on solar metal roofs.

3. Metal roofs are long-lasting enough to outlive your solar panels.

Metal Roof Solar Mounts Make Installing Pv Panels Easy

Ask any solar installer around, and theyll tell you that adding PV systems to a metal roof is one of the easier installation jobs out there. This is because installing metal roof solar panels does not require your installer to drill into your roof.

Because metal roofs are such a durable surface, installers will use your roofs standing seams or tiles to mount and secure panels. This makes installation a breeze and can even save you money on labor costs.

Will Solar Panels Damage A Metal Roof

While they last several decades, metal roofs are a substantial investment. You dont want to do anything to cut the life of your roof short. Even if doing so will bring you decades of free electricity, like with solar panels.

However, as long as your solar panels are installed on par with industry standards, you wont be causing any short- or long-term damage to your roof. In fact, solar panels can actually protect your roof.

While theyre not indestructible, solar panels are designed and installed to withstand a pretty good beating from mother nature. Theyll act as a buffer, shielding your roof from the typical wear and tear over time.

When it comes to securing your solar panels to your metal roof, you can rest assured you wont be exposing your building to any leaks. Solar panels installed on standing seam roofs can typically be installed with no penetrations. Ribbed metal roofs will require penetrations. However, the bolting system is specifically designed to prevent leaks for the lifespan of your solar panel system.

For Solar Panel Systems Installed On Trapezoidal Metal Roofs

Trapezoidal roofing typically has more flat areas in between each peak, and the height of each ridge may vary. As such, brackets for trapezoidal metal roofs also vary in shape.

They are installed with a similar philosophy as the corrugated metal brackets. The idea is to have each bracket fit snugly over each trapezoidal ridge, to ensure optimal drill hole placement above the base level of the roof. Regardless, standard practice for this roof type is to use sealant to ensure there are no leaks.

Just for trapezoidal roof types alone, one leading bracket mount company carries over 15 different types of products.

Be wary of an installer who uses only two types of fasteners for the sake of versatility. Something is likely being compromised to fit, you dont want that to be the integrity of your roof!

    Solar panels are extremely durable and can last for 25 to 30 years, which is part of what makes them such a great investment for your home. However, in many cases, this means that your solar panels can outlive your roof, which can result in an added expense. If your roof is aging, you have to replace it before installing solar panels, or incur the additional cost of removing and re-installing your panels when the time comes to replace your roof.

    Metal roofs, on the other hand, are the most durable conventional roofing material available. If you have a metal roof on your home, it will likely last longer than the lifespan of your solar panels, which reduces expense and hassle in the long term.
