"They did a magnificent job of installation and the clean-up was perfect. They removed the old roof quickly, made sure the roof boards were in good shape and put the new roof on in a little over 1 day. They were careful around my plants. We even were able to get some money back for bad shingles that were used on our old roof and the best part was they did all the paperwork!! When they came over to bid the job they were very professional, had a folder with all the information put together with different roofs in the area we could look at before we made our final decision. I highly recommend them to anyone looking for a new roof!!

Energy Efficiency Auditing questions, answered by experts

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.
