"Pro Home Services was extremely professional right from the start. Eric came out to give an estimate and was extremely knowledgeable about the work that we wanted done. He explained everything thoroughly, which was reassuring. He also provided homes that they had worked on and references for us so that we could feel good about making the right decision. Eric was easy to contact as were the other workers. Once the contract and deposit were signed, we did notice the urgency of responding to our calls and emails was not there any more. However, we were still pleased with their work. We were told the project would start on a Monday but it was the week of the hurricane. We weren't contacted at all that week, even though we understood that they would be delayed. After waiting to hear from them, we called and they told us a new date that they would start, which they followed through with. From the beginning, we kept saying that we wanted the house to look exactly like it had originally but newer. After we came home on the first day of the siding being put up, the width was larger than it had looked originally. This was very frustrating since we kept saying we wanted it to be the same as it had been. Eric explained that the width of the original siding was different in different places so he rounded up to the 5 inch boards. I wish he has clearly stated this to me since I had just assumed that what he wrote in the contract would match what the original siding had looked like. We grew to love the look (especially since we had no money to fix it :) Overall, the worker(s) arrived early each day and cleaned up each evening. They were very helpful when we had questions and the final product looks amazing! They had promised to paint the PVC trim where it didn't match the hardie trim color, which they couldn't do since the project had gotten pushed back and it was too cold. This was unfortunate since they had said they would do the downspouts too but there wasn't anything we could do about the weather. When we had issues come up about the project, they listened and fixed it. They did work above and beyond what other contractors had offered to do. All of our windows got new flashing, we got our porch roof replaced, and they cleaned up some insulation that was sticking out of our attic windows. They even left the dumpster for us to use when they were done. We definitely plan to use them in the future if we need to! You won't go wrong if you choose Pro Home!"

This is probably not your roof:
But, if your roof has damaged flashing, missing shingles, curling, blistering, buckling, rotting and algae growth (which appears as dark or greenish stains), you probably need a new roof.
If you’re roofer doesn’t talk about these, you’re talking to the wrong guy:

"Jeff and his crew were wonderful! I couldn't be happier with both the results and with Jeff, Bruce and the rest of the guys. I was very nervous going into this project, because my home dates back to the 1830's and I didn't want to loose any of the charm or character while at the same time I wanted the energy savings and ease of use of newer products. Jeff explained what my options were, and the pro's and con's of each, and helped me to make an informed decision. My windows now function and look beautiful, my siding is vinyl but you would never know by looking at it and there is energy saving insulation under it, my roof doesn't leak anymore, and I have an extra room off the kitchen! Jeff, Bruce and the rest of his crew were on time, finished in a timely fashion, cleaned up when the job was finished and kept me informed throughout the process. I would definately hire Jeff and Bruce again!"

Insulation FAQs, answered by experts

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

Energy-efficient homes generally have higher appraisals and appeal to buyers.

Insulation can be easy to install, depending on the condition of your walls, but there are many safety considerations and potential challenges involved. For example, most types of insulation are made from materials that can cause irritation if inhaled or if they come into contact with your skin. Additionally, installing insulation incorrectly can actually make moisture issues in your home worse.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.
