"We received a drive-by visit in early September from Presidential Exteriors canvassing the neighborhood and while we knew we were living on borrowed time, with our roof last replaced before 1991, we don't do business with companies we don't know and trust. In this case I said no thank you, and the canvasser made a last comment that struck a chord, to look them up online. After checking their references, even though a fairly new company, they had very positive feedback in Angie's List. I then called and made an appointment and my wife and I were impressed with the salesperson, Ben (we've never had someone climb around the unfinished attic in completing their assessment) for his knowledge, genuineness, detail, and approach, and we signed a contract to renovate our roofing with architectural tiles and to install wider gutters (all in preparation for global warming). Over two days, the crew of two performed an amazing job at removing multiple layers of very old shingles (resulting in less full shingles being removed, and mostly partially torn pieces) and the care and cleanup left the full area around the house and bushes almost clean. Understandably, with any re-roofing I cannot imagine you wouldn't have some small amount of cleanup and a few full handfuls of nails and staples over the following months. In our case, in the subsequent week we have found over 60 nails so far using our own magnetic broom (purchased at Home Depot). The third day found the crew finishing the roofing and the other contractors arriving to remove and install the new gutters. So far, the new roof and rain gutters look great and we're cautiously awaiting the approaching storm season."

"After years of unsuccessfully addressing water damage around windows in an upstairs room by focusing on the window frames and the brickwork around the windows, I asked W. E. Griffin Roofing (whom I had used previously for relatively minor roofing repairs) to evaluate whether the roof was a factor. Matt Hoffman determined that significant work had to be done including substantially rebuilding two dormers, removing and replacing valleys and flashing, and replacing the roof on the dormers. As in the case of previous and subsequent jobs, Griffin's work crew was very professional and conscientious at all times. They cleared all rubble and tools from the site every day, and the job was started and completed on schedule. In the 4 years since this work was done and the interior water damage repaired, there has been no further sign of water damage in that room. I completely trust the advice I have received from Matt Hoffman over the past 7 years since I first used W. E. Griffin. In addition to the work described above as well as routine preventive maintenance, I have also engaged the company to repair gutters, replace incorrectly installed snow guards, replace failed chimney flashing, fabricate and install catch boxes to prevent leaf blockage of downspouts, as well as routine preventive maintenance. I would recommend them without reservation."

"Their work was excellent and timely. They took the time to explain the roofing process clearly to a complete novice. The same can be said for each time I hired Home Matters over the past few years and I will definitely hire them again in future."

"Could have been any more impressed with the pleasantness, punctuality, professionalism and end product. We had a old deck with a huge tree in close proximity to the house. The removed that without even a piece of bark falling on the roof. Having someone that knows what they are doing and are trustworthy is the best combination ever. Deck was huge and they build in storage underneath that was water proof as well. Solid as a rock."

"The estimate process was frustrating and clear as to job price or labor/materials. Then when I communicated and signed doc next day, no call back. Once I got their attention things improved. As for the actual technicians, Fernando and Jesus, they were the best. Knowledgeable and had to make all the correct adjustments for proper installation which estimator did not take into account. The stair railings are beautiful, secure and properly installed. They conferred with me as job progressed as to my choices of height etc. I am so pleased with thei techs. They know their stuff and made a beautiful addition. They worked clean. Drop cloths , shop vac , trash. I would ask for them again. All in all, even with early snags which delayed job, I would work with them again but make a request for these two talented techs."

"The process up to the QA Inspection was excellent. People were friendly and knowledgeable. Austin was excellent at giving honest answers to all our questions. When I asked him one he couldn’t answer he didn’t try to BS his way through, he simply said he didn’t know and then proceeded to make calls until he got an answer. At the Pre-install inspection we were told the install crew would arrive between 8-10. The install crew chief was very surprised to hear that when he arrived at 7. The installation was also excellent. Done and dusted by 4PM. The QA inspection cost you an excellent rating. It was little more than a high pressure sales pitch to replace my aluminum siding with vinyl. I just spent $20K on a new roof and he pressured us to spend another $40K on something that doesn’t need to be replaced. Not cool. I would definitely recommend Power, but with a caveat on the QA inspection."

FAQs for heating cable for roof installation projects in Rockville, 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.
