"American Home replaced my roof and siding, porch windows and some add-on exterior lighting. One of the reasons I chose AHR was not just due to the best price, they came in line with other estimates I received, but because they included things with their final price that similar companies had as add-ons at an extra cost such as the dumpster and gutter system. I did not know what to expect as this was the first time I've had these things replaced. My rep John was awesome, he was professional, friendly and accommodating, and was able to work with me on the spot vs. "I have to check back to the owners" which I got from other companies. John was readily available by phone, text, and in person. He walked me through all the steps, timelines, and the whole process. After the crew finished, he took my list of 'nit-pick' things and made sure they were addressed. Overall I am satisfied with the job, In fact, we recommended them to our neighbors who hired them to do their siding this Spring."

Welcome to Santosusso Construction! Located in Philadelphia, PA. Covering the Tri-State area. We are licensed & insured, offering free estimates. We specialize in residential work including: New Construction, Total Gut Renovations, Remodels, Additions, Decks, Kitchen / Bath, Roofs,Concrete,Basement Dig-outs, Brick Fronts, Demo, Etc. I'm Steve Santosusso owner and operator of Santosusso Construction Inc. Santosusso Construction has been a licensed company since 1988, beginning in Los Angeles, California. After being involved in construction for a number of years, I attended and graduated from Pacific Coast Contractor's School. The curriculum included general knowledge of all trades, estimating, and OSHA laws. In 1993 I moved my company to the East Coast where I've been licensed in PA ever since. We are a small personal company with hands on attention to every project. Our employees are well trained and trust-worthy, as are all sub-contractors, whom I have used for many years. This combination of employees and sub-contractors provides a team atmosphere with quality work as our goal. Check us out on Facebook: https://www.facebook.com/SantosussoConstructionInc/

"Santosusso Construction did an amazing job on stepping in to save the day on a fix and flip project that was started by a previous construction company. It would have been completely understandable if Steve, the owner, would’ve opted out from doing the work. But instead, he jumped in, provided a fair price and brought only licensed and expert tradesmen onto the project to get the property sold. After experiencing his dedication to this project, and seeing first hand that he went above and beyond of what was expected, I hired him to renovate my home. Steve is very thorough, honest and was always ready to answer any questions that I had. He kept me updated daily regarding the progress of the construction and assured me that the renovation would be done on time. I would highly recommend Santosusso Construction over any other construction company in the Delaware Valley. And I will 100% be using them again in the future."

FAQs for addition to existing structure building service projects in Magnolia, NJ

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.
