"I needed a new roof and wanted gutters and gutter covers. After meeting with one other company, I selected Roofing Pups. Shawn of Roofing Pups was friendly, mannerly, professional, and knowledgeable. He offered a much better deal that included everything I wanted, at a reasonable price. Whenever I called Shawn or his colleague, they responded by text or phone within seconds. The project was completed in three days, and cleanup was done daily. All staff and workers were friendly, professional, and well-versed in their skills. The workmanship was superb! After the work was completed, it rained hard the next day. There were no leaks, rain was flowing away from my home as it should, and the appearance of my house looks great. Overall, I’m a happy customer and would recommend Roofing Pups to friends and family."

"Certified roofing did very well. They were the first to respond to my Angi query. Tim was smart, quick, and had an excellent work ethic. We had a slight miscommunication on what the job entailed, which is being cleared up as we speak. I would definitely hire them again."

"We hired Cox to repair/replace the both sides of the church's pitch roof at Our Lady of Hope Church in Dundalk. They took off the old roof, added plywood, new cloth and shingles. We are talking about a roof that is 1000's of square feet! The job was done within the allotted time. The clean-up was superb! The price was 17% below the closest bid price. A most excellent result from a fantastic company."

"We appreciate the thorough inspection that Zachary and Andrew conducted, including inspection of the attic. From the many photos they took of the roof, we can see that they did several maintenance repairs, including caulking, re-nailing, etc. They discussed with us the condition of our roof, explained what they found and the maintenance/repairs they had performed. They also discussed with us new roof options when it is time to replace the roof. We found both Zachary and Andrew to be personable and professional, and we look forward to seeing them again when we have additional roofing needs. Susie Setser"

Roofing FAQs, answered by experts

The easiest way to tell if your roof vent boot is leaking is to look in your attic for signs of water damage. You might see visible moisture, water spots, or mold on the roof decking around the roof vent or damaged or soggy insulation below it. If you don’t have access to your attic or aren’t sure if the vent boot is the issue, hire a professional to come inspect your roof and figure out the underlying issue.

Asphalt shingles are the least-expensive roofing material. They cost around $10,000 for a 1,600-square-foot home compared to $16,500 for metal roofing or $25,000 for slate shingles.

The material and frequency of maintenance are the biggest factors for determining the longevity of your shingles, not the color. For instance, luxury asphalt shingles can last 30 years or even longer, while slate tiles have an impressive lifespan ranging from 75 to 100 years. That said, lighter-colored shingles can help reduce your energy costs in the summertime.

Furring strips (also called wood stripping) are not always necessary for a metal roof installation, but they are highly recommended and may be required by local building codes or the roofing manufacturer's specifications. There are several key reasons to use them:

  • Energy Efficiency: Furring strips, made of wood or metal, create an air gap between the metal panels and the roof deck. This acts as a thermal break, reducing heat transfer into your home and improving overall energy efficiency.

  • Moisture and Condensation Control: The air gap allows for better airflow, which helps prevent moisture buildup and condensation under the metal panels.

  • Structural Support: They provide a solid, even frame to which you can attach the metal roofing panels.

It is especially important to use furring strips when installing a metal roof over existing shingles. Without them, the roof surface can be uneven, and you will experience greater solar heat gain.

You can secure roof decorations like inflatables and other Christmas decor by tying a rope or attacking bungee cords to your roof clips. Depending on the pitch of your roof, you can use sandbags for extra support. Like with Christmas lights, avoid using staples or duct tape.
