Top 5 Energy Efficient Home Improvements and their Costs – Green Home Ideas

Are your ready to make your home greener and more energy-efficient? If so, consider the following five home improvement upgrades that can be completed by a professional remodeling contractor, as well as by an experienced DIY enthusiast working collaboratively with a handy friend. πŸ˜‰

1. Cool Roofs Vs. Traditional Asphalt and Dark EPDM Rubber

Dark roofs make houses hotter, light roofs make houses cooler. To achieve these benefits a specialist applicator can coat your roof with reflective materials, some of which are applied like paint, sprayed directly on the surface of an existing roof. Of course, this is often, but not always, a one-season solution.

Energy conservation wizards are currently working on tiles that will go from light to dark as needed — they can cut the sunlight absorbed into your house by 80% when they are white and slice heating costs by 20% and more when they turn black.

You can find a cool roof coating formulated with acrylic polymers, resins, fillers and titanium dioxide pigments for about $100 for a 4.75 gallon container (Via GreenHomeGuide.com).

If rather than applying it yourself, your would prefer to hire a professional, expect to pay anywhere from a few to several thousands of dollars to properly apply a liquid roof coating. You should know that most liquid roof coatings are only suitable for durable membrane-based flat roofs and aging metal roofs.

Surely, cool liquid roof coatings can also be applied over asphalt shingles, but the results will not be as good, because asphalt shingles have a tendency to chip and crack. Thus, a complete re-roofing application may be a better option for an aged asphalt roof.

If you have a flat or low-slope roof that is starting to show the signs of age, and may thus require replacement soon, then consider installing one of the following membranes; white, energy-efficient and solar-reflective PVC membrane, TPO membrane, or white EPDM rubber roof. Expect to pay from $4.50 to $6.00 per foot for EPDM rubber membrane installed. A PVC or TPO membrane will cost about $5.50 to $7.50 per square foot installed.

2. Metal

Today’s metal roofs have come a long way from the tin shacks of yore. Modern metal roofs are as likely to look like cedar shakes or clay tiles or asphalt shingles as sheet metal. A metal roof won’t blow off in hurricane-force winds and is fireproof.

Metal roofs will cost more to purchase and install than traditional asphalt roofs, but will still be on the job half a century from now, while two or three asphalt roofs are clogging landfills. πŸ˜‰

Steel Shingles Roof

Expect a metal roof comprised of interlocking shingles to run around $3.50 to $4.50 per square foot for materials including trim. With the installation, a metal shingles roof will cost about $7.50 to $10.00 per square foot.

concave-shaped standing seam roof

Materials for galvalume standing seam will cost about $4.50 to $5.00 per square foot. With the installation, a standing seam metal roof will cost about $10 to $12 per square foot, not counting the expense of a roof tear-off.

During winter, an energy efficient metal roof, such as standing seam or metal shingles will help shed the snow off the roof, before the snow has a chance to accumulate. It can thus be an energy-smart and elegant alternative to heat cables and/or snow rakes commonly employed to deal with the ice dams on the roof.

PV Solar Panels on Metal Roof

Speaking of home energy efficiency, another major advantage of a standing seam metal roof is that it is solar roof ready. Meaning that it can be simply and elegantly combined and integrated with PV solar panels by means of simple metal clamps via a bracketing systems attached to the seam. This method does not require drilling any holes (potential future sources of leaks) in the roof

3. Energy Efficient Window

Windows are among the biggest culprits in creating high energy bills. But no one wants to live in a house without windows. Double-pane windows are one solution; they will retain room heat in the winter and prevent heat gain in the summer. At the same time the double-panes will keep your house bright and sunny. And a little quieter as well — the extra layer of glass helps prevent outside noises from penetrating the windows.

Most average-sized double-pane windows will cost anywhere from $500 to $700 installed.

There is more to double-pane windows than two pieces of glass. Low-E glass, filled with argon gas provides the ultimate in insulation over a single-pane window. Expect to pay about $40 extra per window. But more is not always better when it comes to window panes. Triple-panes can be a help in the harshest climates, but they come at a cost of reduced clarity in looking to the world outside.

4. Green Frames

The frames your windows live in are opportunities for the green-minded remodeler. Wood offers the best insulation but may deteriorate prematurely in a rainy climate. Plus, they are going to need new coats of paint every few years. If that means latex paint, that will douse your interior air with a bucket of noxious petrochemicals (there is a reason paint requires special disposal techniques). Eco-safe paints are getting better every year with more durability and a wider variety of people-pleasing colors. And they are less costly at the cash register as well.

It is hard to beat the look of wood on windows and that preference can trump green tendencies when it comes to alternatives such as vinyl or aluminum. Vinyl is budget-friendly (from $450-$600 as opposed to between $800 and $1,000 for the installation of wood windows) and no trees are destroyed, and aluminum can be a good choice in rainy climates.

5. Insulation

attic insulation

Seal and insulate, seal and insulate, seal and insulate. That is the manta of energy-efficiency, but green-minded homeowners can take this basic Eco-friendly chore one step beyond. Spray insulation or traditional batting insulation is loaded with chemicals. Soy foam works the same insulating magic without the environmental downsides.

Home insulation is where the true green converts are separated from the wanna-bes. Closed-cell spray foam is a pricey insulation option, costing between $3.00 and $3.50 a square foot in walls and another $1.00 per square foot for attics. Soy foam will work as well as cheaper and more readily available fiberglass-based batting insulation, but not so much better that it will be a boon to your pocketbook in the long run. You won’t recoup the costs of hidden soy insulation at resale. This is one financial bullet you will be taking for the good of the planet. πŸ˜‰

Why Standing Seam Solar Metal Roof Blows Tesla Solar Roof Out of the Water!

Right off the bat, we love Tesla Solar Roof and what Elon Musk is doing to disrupt the solar roofing market.

But, the reality is that despite its revolutionary style, great looks, and the bold promise “to rid your roof of those bulky and unsightly solar panels”, Elon’s new product is way too expensive and unaffordable for a typical American household.

That’s right, outside of the upper middle class families in Los Angeles, San Francisco, Austin, Seattle, and other major, affluent tech hubs, most regular people don’t have that extra $50,000 to $65,000 to shell out for Tesla’s new and unproven Tesla Solar Roof.

Furthermore, at this point, the new product from Tesla is completely unproven in terms of the roof’s ability to withstand the elements and remain leak-free for the duration of its intended lifespan.

Granted, every product has to go through a product adoption life-cycle curve, but unless Tesla solar roof pricing changes drastically, we don’t see a mass market adoption of this promising new product happening any time soon.

What’s more, should the government decide to pull a plug on solar tax credits, then Tesla solar tile roof will be dead in the water, again due to its very high cost.

Top 3 Roof Issues to Address Before Installing Solar Panels

PV solar panels for residential roofs are in like never before, thanks to the fact that going solar has never been easier or more affordable.

The Price of Going Solar Has Decreased Dramatically Over the Past 10 years

In fact, according to EnergySage, in 2017, most homeowners are paying between $2.87 and $3.85 per watt to install a new solar system, and the average gross cost of a residential PV solar power system before tax credits is $16,800.

Did you know? Less than 10 years ago, in 2008, the cost of a solar power installation was $8.82 per watt.

Using the U.S. average for system size at 5 kW (5000 watts), a new solar system cost will range from $10,045 to $13,475, after tax credits. — That’s a rather attractive price range for residential solar energy compared to the recent past.

historical cost of solar power on a per watt basis

So, should you jump on the solar bandwagon and take advantage of the solar tax credits available to homeowners in 2017 right away, or are there other factors to consider before installing solar panels on your home?

There are several important factors to consider before calling a solar company and getting those panels up on your roof, if you want to ensure a lasting and regret-free solar installation:
