Traditionally in the Midwest, homes are insulated with fiberglass or cellulose insulation.  However, a newer trend being seen in homes is the use of spray foam insulation.  Just as the name implies, this type of insulation comes in spray cans. It’s a combination of resin and chemicals such as polyurethane & isocyanides.   As the insulation is sprayed, it expands and fills up the entire area it is being applied to.  The term “hot roof” comes in because the spray foam insulation is being affixed directly to the roof sheathing which removes the need for ventilation.

How Do Hot Roofs Differ From Traditional Roofs

Attics typically have an insulated floor and have ventilation.  Air from outside is permitted to come in through the soffits and exit through the top of the roof which creates a cold attic during the winter months.  This method is intended to deter ice dams by keeping the roof cooler. When your attic is filled with spray foam insulation to create a hot roof, your attic’s temperature rises because the thermal envelope is shifted to the underside of your roof because ventilation is not present.

Hot Roofs & Roofing Warranties

Industry studies show that shingle temperature is only raised by a few degrees with a hot roof.  However, these few degrees can lower shingle lifespan by up to 10% and cause shingles to fade.  GAF, North America’s largest manufacturer of residential and commercial roofing, offers a “Golden Pledge” warranty which covers roofing material and labor for 50 years.  This warranty is not pro-rated.  However, those with a hot roof are not eligible for GAF’s highest level of warranty because a hot roof does not have the insulation standards that their asphalt shingles were designed for.  Before moving forward with a hot roof, check with your roofing manufacturer to make sure that doing so will not void your roofing warranty.  Be sure to check with your city to see if they have restrictions on hot roofing before proceeding with your project.

Perks of a Hot Roof

The unit of measurement for insulation is called the “R-Value”. The R-value measures how well insulation is able to resist heat going through it. The bigger the R-value, the better it will insulate your home.  A hot roof contains the highest R-Value because there are no chances for air to leak.  If the attic contains ductwork, it won’t need to be insulated because there is no energy loss.  A hot roof prevents energy loss and can lower your utility bills.

Smart Water Consumption at Home

Filed under Home Maintenance, Water Conservation
Tagged as , , , , , , , , , , , ,

Did you know that if all the water in the planet fit into a gallon jug, only 1 tablespoon (less than .5%) would be fresh water?  The U.S Environmental Protection Agency (EPA) states that the average American household with 4 occupants uses an average of 400 gallons per day, a majority of which is used indoors.  Smart water consumption saves you on energy bills and also makes for a more sustainable way of life. Below, we’ll offer some easy ways to conserve water without making major lifestyle changes.

Toilets: Your toilet can be responsible for as much as 27% of your home’s daily water consumption.  WaterSense toilets can reduce the amount of water used after each use but up to 80%.  Fix or replace a leaky toilet and conserve up to 200 gallons per day. 

Signs Your Toilet is Leaking:

-It won’t flush unless you hold the handle down to fully empty the tank

-Handle must be fidgeted with to get toilet to stop running

-Toilet makes sounds after being used

-Toilet runs for a long time after a flush

Not all leaks are obvious.  To test whether your toilet is leaking, flush and then remove the tank cover and add a teaspoon of food coloring.  DO NOT flush; wait an hour and then check your toilet bowl for food coloring.  If food coloring is found, it is a signal that a leak is present.  Consult with a reputable plumber about how to remedy the issue.

Faucets: Turn off the tap while you brush your teeth and save up to 200 gallons of water per month.  A faucet continuously dripping can often be fixed with something as simple as replacing a broken washer.  Eliminate the need to run the faucet until the water is cold enough to drink by keeping a pitcher of filtered water in your refrigerator.  Aerators control faucet water flow and screw into the faucet’s spout.  Switching to a low-flow aerator at the end of your faucets allows you to cut back on water usage.

Washing Machine:  Today’s high efficiency washing machines can use half the water that traditional models do.  Wait until you have a full load before you running your washing machine.  A cold load uses less energy than a hot one because the water does not have to be heated.

Shower Heads: Switch to low-flow shower heads to conserve water.

Dishwasher: A full load in the dishwasher will actually use less water than doing the same amount by hand.  Avoid running the dishwasher unless it is full.

Water Heaters: Unlike traditional water heaters, tankless models heat water as you use it.  Depending on the model you select, you can choose to supply only certain faucets or the entire home.

Rainwater Harvesters: Rainwater harvesting is collecting the run-off from a structure in order to store it for later use.  Rain collects in your gutter system that channels the waters flow into downspouts moving it into a storage vessel. There are many different types of rainwater harvesting systems and they range from systems that are as simple as a rain barrel or as detailed as large cisterns that can supply your entire household demand.  They allow you to be in control of your water supply and the collected water can be used in toilets, sprinkler systems, swimming pools and washing machines. It can also be used wash your car, pet, or water plants.

Sprinkler System: Double check to make sure your sprinkler system is watering your lawn and not your driveway or sidewalk.  Water in the morning or in the evening when water is less likely to evaporate quickly.  Avoid watering when it’s windy out because the water will not end up where you intend it to.  Mulch your landscaping to help it retain water.
