"Very Pleased with Home Genius. John our project manager was on site through the entire installation and answered any and all questions we had. He also went above and beyond and repaired our radon system that had not been installed properly , he personally made sure it was vented out the roof and not just blowing into the attic like the original installers left it."

"Was away when the work was done, but when we returned you would never know they were there - except for the new roof. There appeared to be a leak which I assumed was caused by the new roof. When they returned to inspect they found that another part of the roof which they were not responsible for was the culprit. They did a minor fix - w/o charge and the problem has not occurred again. Awesome."

"I couldn't be more pleased with the outstanding service provided by J. Cwanger. From the very first call regarding a roof leak, their team was professional, responsive, and incredibly helpful. Their initial inspection and diagnosis were thorough, and they provided clear explanations of the necessary repairs. Throughout the process, communication was seamless, even with the added complexity of coordinating with my loan approval. I truly appreciated their patient and understanding approach, as they never pressured me for a sale and consistently kept me informed about scheduling. Once my loan was approved, J. Cwanger's team was on-site within days. The roof replacement was completed in a single day, a testament to their efficiency and skill. During the work, they identified and addressed unforeseen issues with the underlying plywood, demonstrating their commitment to thoroughness and quality. What truly impressed me was their follow-up after a significant rainstorm. The team proactively came to inspect the roof the next morning, ensuring everything was functioning as expected. This level of dedication and customer care is rare and greatly appreciated. J. Cwanger came highly recommended, and I now understand why. Their professionalism, efficiency, and commitment to customer satisfaction are truly exceptional. I wholeheartedly recommend them for any roofing needs."

FAQs for natural slate roofing repair projects in Cape May, NJ

If more than 30% of your slate roof is damaged, it's time to consider a full replacement. This will prevent further deterioration and avoid costly recurring repairs. A professional slate inspection (costing between $130 and $360) can confirm whether repairs are sufficient or if a full roof replacement is the better option.

A slate roof can last anywhere from 60 to 150 years, depending on factors like installation quality, regular maintenance and repairs, and local weather conditions. Compared to materials like clay and concrete, which often last around 50 years, a well-maintained slate roof offers superior longevity, durability, and long-lasting aesthetic appeal.

Yes, you can use temporary patch solutions, such as roofing cement or patchwork, to provide immediate relief for minor leaks or underlayment issues observed from inside your home. However, these provisional fixes do not replace the need for a permanent, professional exterior repair, which is necessary to ensure the long-term integrity and weather resistance of your slate roof.
