The solar roofing industry is growing at a rapid pace. A lot of that has to do with the continued drop in costs for installing these systems. You can now buy solar roofing systems from major home improvement retailers, so there’s no need to go out and buy specialized equipment or hire a contractor to install them. If you’re interested in installing a solar roofing system on your home, check out our blog article explaining how they work.
Solar roofs are as easy to install as any other type of roofing material. Installing a 5 mil polyethylene membrane (or polyisocyanurate) under your existing roof is relatively simple, requiring only a few extra steps depending on the type of solar panel you choose and how much added insulation you have in your attic.
What is a solar roof?
A solar roof is a type of rooftop system that contains solar photovoltaic panels. The panels are used to generate electricity and convert sunlight into clean, renewable energy.
A solar roof typically consists of several layers of photovoltaic sheets, which work in tandem with the insulation layers to keep your home cool during the day and warm at night. They can also be used to reduce heating and cooling costs for your home by capturing heat from the sun and storing it throughout the day.
Solar roofs are a great option for homeowners who want to increase their income on their homes through solar power or for homeowners who want to decrease their carbon footprint (since they don’t have to rely on fossil fuels).
Pros and cons of a solar roof
The benefits of installing a solar roof are many. You can lower your electric bill by up to $30,000 over the lifetime of the system and potentially save thousands in maintenance costs as well. Solar roofs also reduce noise pollution, which is especially important for those living in urban areas where land is limited.
One potential downside to this type of roofing material is that it doesn’t provide protection from hail or wind damage like other types of roofs do. If you live in a place that experiences extreme weather, you may want to consider going with one of the more traditional materials.
There are several different types of solar panels that you can use for a solar roof. The most common type is mono-crystalline silicon panels, which come in 310 watt and 350 watt sizes. Solar panels range in price depending on their size, efficiency rating, and brand name.
A solar roof typically comes with a warranty as well, so if there’s something wrong with your installation or the panels don’t produce as much electricity as they should you’ll be covered with repairs or replacements.
Type of roofing material used for solar roofs
As is often the case, the type of roofing material you choose to install can make or break your system. If you’re not familiar with solar roofing options, it might seem like any old roofing materials will do. This isn’t true. Certain types of roofs are more conducive to the application of solar panels, and they don’t require much maintenance.
Polyethylene membrane (or polyisocyanurate): These types of membranes are probably the most common type of substrate used for solar roofs. They are inexpensive and easy to maintain as well as provide a lot of insulation against heat gain, which is important for a home in Arizona or New Mexico where temperatures can rise into the triple digits during the summer months.
Tin-foil: Tin-foil roofs are popular among farmers because they can be installed quickly and require little maintenance and cost very little to install. They also offer some dose of insulation but aren’t able to withstand extreme temperatures very well; this makes them less suited for areas with high summertime temperatures like Phoenix or Tucson than other solar roofing systems would be.
Metal: Metal roofs can also be used for solar roofs and have some benefits over tin-foil in that they maintain their shine through longer exposure to heat without getting duller over time and are able to withstand extreme temperatures better than tin-foil. However, metal roofs need a lot more upkeep than other types, which might not be worth it
Which type of roofing you should choose for your home?
Which type of roofing you should choose depends on the style of your home and what you’d like to accomplish with your roof. A thin-film solar roof is best for homes that are new or want to increase the energy efficiency of their roofs, while a thick-film solar roof is typically better for homes that have a more traditional look.
If you want to go with a thin-film solar roof, you will need a 100 percent in-floor insulation. This means that any insulation in your attic, if present, needs to be removed. If it is not removed, there could be an issue with airflow and heating your home. The key here is to get whatever insulation you have properly installed before installing the solar panel system.
If you want a thick-film solar panel or an integrated photovoltaic (PV) thin film system, then the existing insulation on your home can remain intact at no added cost. This makes for easier installation because there is less work involved in getting everything installed before beginning installation on the roof itself.
Installation of a 5 mil polyethylene membrane under asphalt shingles
Polyisocyanurate is a type of insulation that allows heat to pass through, but protects against cold and moisture. It’s also known as polyiso.
To install the polyisocyanurate, you’ll need a few tools:
– tape measure
– drill with a 5/16″ bit with an adjustable collar (if you don’t have an adjustable collar, it’s fine to use a standard bit)
– caulking gun or caulk tube (either will work)
– utility knife
– sawtooth or jigsaw blade for cutting out vents in your existing shingles
– angle finder for measuring roof pitch
– straight edge to help guide the sawtooth blade
Installing an installed Tefzel® sheet under shakes and tile
If you want to get a little more out of your solar roofing system, it’s a good idea to install one or two Tefzel® sheets under the roof. Your roofer will cover these with shingles and then seal them in place with the appropriate layer of asphalt. This extra step requires some extra labor, but can save you on electric bills and make your house feel warmer.
Installing an installed black flat sheet under black top granules
Solar panels need to be installed on a flat roof, so the first step is to install an installed black flat sheet under black top granules. The solar panel mounts onto the roof and the membrane goes over it.
The next step is to lay down glass or tempered glass shards across the roofing membrane that make up your solar roof. There are many types of solar panels available-some are made from copper and some have better yields than others depending on where you live and how much sunlight you get.
Next, lay down a layer of traditional roofing tiles in a pattern that matches your style and color scheme. Traditional tiles are great for homes with lots of windows because they allow light into your home without as much infrared radiation escaping through them as other types of roofs materials do.
After laying down traditional tiles, choose shingles or shake-style tiles that match your color scheme and position them according to building codes. If you plan on placing a skylight over the solar panel, point it towards south so your house gets plenty of sunlight during the day and less during night hours when power demands drop off significantly.
Shading value of a solar panel installation with black shingles and flat-black insulation
Solar panels are not the only option for your roof. Consider installing a solar panel system with black shingles or polyisocyanurate to generate electricity and shade your roof. Black shingles offer a unique aesthetic and provide valuable insulation from the sun. Flat-black insulation is another way to add energy efficiency and help reduce heat gain in your attic while making a home more comfortable and livable in hot weather.
A lot of homeowners are interested in switching over to solar power because they want something special or different on their home. Adding these features may even increase the value of your home, as buyers may be more interested in homes that have environmentally friendly features like solar panels and black shingles.
