"WORST SERVICE ON THE MARKET. THIS COMPANY LEFT MY GRANDMOTHER $14k in DEBT, after recommending top teir gutters. The gutters were NOT needed. Not only did the company install the gutters poorly, they do not work. They do not work because she needs a roof, not new gutters. This horrible company recommended $14k gutters when a ROOF was needed. Now she will have to take down the gutters, and put up a new roof. KICKER - they fell into her garage door and left it damaged/non-functioning. DO NOT ..... I REPEAT ..... DO NOT USE THIS COMPANY. You can see in the pictures below how gutters should never have been installed on this house. Also can see how they do not work (icicles behind). Imagien $14k for gutters that do not work. RUN from Home Genius. Their response a week later: Ambrose Powell 1:45 PM (53 minutes ago) to Jeff, me, Austin, Victoria Bill, I respect that you are a busy person and that is exactly why I gave you a multitude of options for a scheduled phone call. After you agreed to talk at 9:30am I called you exactly at that time, you did not call me back until 11:50am in which you apologized for missing my call and told me you appreciated with me sticking with it. I too am a busy person and scheduled phone calls with other customers as well as additional meetings when you gave me the agreement of 9:30am.

Natural slate roofing repairs FAQs

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.
