Ken Cook has been installing residential roofs and ventilation systems for over 35 years. Cook's Roofing is certified by the Certain Teed Corporation to operate as a select shingle roofing company. This allows our company to extend material and labor guarantees for longer periods than the competition. Cook's has two crews and two lead roofers are certified Master Shingle Applicators. Our foreman has been employed by us for over 13 years. According to the building inspector's office, Cook's pulls more permits for roof construction in the town of Bellingham than any other contractor. In 1992 when many of the shingle manufactures were having trouble with their fiberglass shingles, the ASTM (American Society of Testing and Materials) developed testing for shingles that showed many problems with roof shingles. It was right then and there that Ken Cook decided to install the best shingles available and have quality that people could depend on; CertainTeed is the best company for their materials and warranties. They have taught us every aspect of the roofing industry from proper installation techniques to knowledge of how to know the difference between shingles that are of a high product quality and mediocrity. Ken Cook has been a resident of Bellingham for over 50 years. He is an active member of the First Baptist Church of Bellingham serving Christ and the community. He also serves on the finance committee of the same church. Ken is married; they have 2 daughters and 2 grandsons. Ken loves Jesus, (John 5:24) his family and roofing.

"I had a FANTASTIC experience with LCT! It started with a prompt response from them, setting up an appointment the next day after a tree fell on my house. James came down and explained everything thoroughly and gave me some options. After talking to a few other vendors, I knew I wanted to go with LCT. Their pricing was better than the other quotes and James was great to work with. Before the crew started any work I met the owner, Luis, and knew I had chosen the right company. He was just as great as James, very thorough and let me know what would be happening. In addition to needing the roof replaced we also had some damage to rafters and decking to replace. After the job was complete, Luis did a thorough inspection of the work and made sure I was happy with everything. The crew did an amazing job and I couldn't be happier with the work. The office staff was also great to work with! I got to meet them when I went down to pay the invoice. A 5 star experience from start to finish. Thank you LCT!"

FAQs for home energy audit projects in Mendon, MA

To prepare for a home energy audit, begin by preparing your space. Clear any obstructions around the attic, basement, ducts, crawl space, appliances, windows, and doors. Gather all your energy bills from the last year and information on home upgrades if you’ve made any changes. If you’ve previously had an audit done, include that information as well.

Finally, be prepared to discuss any questions or concerns you have. If you’ve noticed a rise in your energy bills, hot or cold areas in your home, or unusual sounds from ducts or appliances, make a list to discuss with your auditor.

How often you should get an energy audit depends on the age and condition of your home. New homes with no issues are recommended to get an audit every five years, while older homes should audit every two to three years. If you’ve noticed any changes to your energy bills or other areas of concern, you should get an audit as soon as possible. It’s also a good idea to conduct an audit if you’ve made changes or upgrades to your home, such as installing a new furnace, windows, or doors.

An energy audit takes three to four hours to complete. Your auditor sets up testing equipment, conducts an exhaustive walk‑through inspection, and performs all required evaluations to identify energy loss points. The audit follows a systematic review that includes visual assessments, mechanical tests, and detailed documentation, resulting in a precise report of improvement recommendations.

You can schedule a home energy audit any time of the year—it all depends on what's convenient for you. That said, timing it right can help you tackle issues before they impact your comfort and bills. If you live in a colder climate and want to avoid high heating costs in the winter, getting an audit in the summer allows you to make improvements before the temperature drops. On the contrary, if hot summers are your concern, a spring audit can help you stay cool and save on air conditioning.

To find a qualified home energy auditor, start by searching for local energy auditors with great reviews and recognized certifications like those from the Building Performance Institute (BPI). These credentials ensure they're qualified and can help you qualify for rebates. Don't hesitate to ask about their audit methods and schedule a consultation to see if they're a good fit for your needs. Doing some research upfront helps you get top-notch service and maximize your energy efficiency.

Once you have your energy audit report, it's time to take action. Review the recommendations and prioritize the upgrades that make the most sense for your home and budget. Reach out to experienced pros to get quotes and discuss how they can help. By making these improvements, you'll boost your home's energy efficiency, lower your utility bills, and enjoy a more comfortable living space.
