Customers say: Super punctual

"I can't say enough about A P Builders and how absolutely wonderful they have been from start to finish. We completely gutted and remodeled our home and Angelo was upfront, honest, timely, and everything that was contracted was done to perfection. We had crew there every day from start to finish. He started on time and finished on time. Any change orders were handled professionally and solutions were found for any unforeseen challenges due to the age of my home. I highly recommend AP Builders for any of your home improvement needs."

"We’re currently mid-construction with Icon and couldn’t be more pleased with the experience. Communication has been outstanding — they keep us informed at every single step of the build. They use an app that lets us follow along with progress in real time, including photos, so we always know exactly where things stand without having to chase anyone down for updates. It’s been a smooth, transparent process, and that level of visibility has made building a home so much less stressful. Highly recommend Icon to anyone considering a custom build."

"They built a full porch after they took down my existing small stoop porch. It looks better than I could have ever imagined. They explained everything as they went was a great experience."

"Jim from Independent Remodeling is a great contractor who works with a great team and I highly recommend him to anyone. He helped us out when another contractor abandoned our complete Rehab job and gave us a great price and was SO patient with the whole project. We ran into problems and delays with both the bank and the city and Jim was great about it all. His team did an excellent job on our home and we are very happy with the time it took and the end result. He is reasonably priced and works with your budget as much as he can and he stands behind his work!We will definitely be calling him for future projects!"

"contacted T&K Builders after discovering mold in my exterior wall, and their response was immediate and professional. The team quickly demolished the affected area and installed the necessary structural supports to safely hold the roof. Everyone on site worked efficiently, communicated clearly, and maintained a high level of professionalism throughout the process. They kept the site clean, protected materials from the elements, and were extremely organized—especially important since we received over four inches of snow the following day. From start to finish, the experience was seamless and stress-free. Their attention to detail, workmanship, and respect for the property truly set them apart. I would absolutely recommend T&K Builders for any future projects and would not hesitate to call them again."

"Working With Damion was great. The ease of doing business is what I focused on. He was very straightfoward and offered opinions on our layouts. He did not tell us what we wanted to hear. We would absolutely hire him again."

FAQs for addition to existing structure building service projects in Algonquin, IL

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
