"Daniel was very professional in addition to reviewing the job, he assisted me around the house. Specifically around the downspouts even though he was not asked to. Crew was excellent. They did a very good job they assigned here except the noise of putting up the siding :)"

"Spent ~$50,000 on a new roof with them. Thought everything went well. Years later discovered that they had not sealed the cricket on the chimney well enough. Discovered water coming in and eventually rotting the wallboard, studs, etc. Had to replace entire wall. Called them about the issue, they sent a rep. He said it was the chimney's fault, it was leaking. Not so, opened the wall and ceiling and had another roofer come spray water on the chimney, nothing, no leak. Then sprayed water on the cricket, water came in. Exterior Medics would not admit any fault. Had it repaired, no leak, no problem since then. Had recommended to a friend, never gain, he also had a bad experience. DO NOT USE IF YOU WANT QUALITY WORK AND A COMPANY HAT STANDS BEHIND THEIR WORK."

"If you're searching for a reliable company to replace your roof, I highly recommend Certified, a Service-Disabled Veteran owned business. From my very first phone call with the owner, Steve Mitchell, I was thoroughly impressed by his professionalism and genuine approach. His guiding principle is “do the right thing always,” and he truly listened to my concerns, promptly arranging an appointment to move forward. At our meeting, Steve EPITOMIZED EXCEPTIONAL CUSTOMER SERVICE - he listened intently, thoughtfully answered every question, and addressed all my worries. He explained the entire roof replacement process in clear, easy-to-understand terms. When it came to areas where the wood was damaged under the shingles, Certified sent me detailed photos of the damage, then replaced and numbered the plywood so I could see exactly what was done. I received before-and-after photos, and I have to say, if a roof can be beautiful, nine is absolutely stunning and comes with a 50-year warranty! "

FAQs for heating cable for roof installation projects in Kensington, MD

A typical heat cable uses 5 watts per foot, regardless of the outside temperature. So, if your cable is 100 feet long, it uses 500 watts per hour. Expect to pay an additional $40 to $200 or more per month on your electricity bill. Be sure to turn manual cables off in the summer when you don't need them.

To install heat tape on your roof, place it along the lower edge in a precise zig-zag pattern to maximize coverage and heat distribution. Professional installers secure the tape with specialized clips that attach firmly to your shingles. This method ensures even heat distribution to effectively melt ice and snow while maintaining your roof's integrity during severe winter conditions.

Choosing between heated gutters and roof heating cables usually comes down to budget, appearance, and performance. Heated gutters cost less to install and blend seamlessly with your home’s exterior, making them a discreet, lower-cost option for preventing ice dams. Roof heating cables deliver more customizable and powerful heat along roof edges to handle heavy snow and ice, but they require more material and labor, increasing your upfront investment. Evaluate your roof design, winter weather demands, and energy budget to select the system that works best for your property.

Roof heating cables prevent ice dams by melting snow and stopping ice buildup at the roof edge. Ice damming occurs when melting snow refreezes on a cold roof—often right above the gutter line—and blocks water from draining, which can force moisture under shingles into your home. Heating cables maintain a warm channel that clears ice dams as soon as they form and protects your roof from water damage and structural issues.

Roof heating cables last between two and ten years before replacement is needed, wearing out faster than your roof itself. Their lifespan depends on climate severity, cable type, and exposure to physical damage. Consistent inspections and preventative maintenance—such as clearing debris, tightening clips, and checking electrical connections—can extend their service life and ensure reliable snow and ice protection each winter.

To safely remove snow from your roof, start with a specially designed roof rake, standing firmly on the ground and pulling snow downhill rather than climbing onto the roof. You can also apply calcium chloride ice melt to break up stubborn ice or gently use a secured rope from a safe vantage point. 

Keep in mind that large snow slabs can weigh hundreds of pounds and pose a serious fall risk. If conditions are hazardous or you lack the right equipment, hire a professional to protect your safety and your roof’s integrity.
