"We used Mike Bennett of Springfield Roofing because we trust him. He's been their in the past when we needed him and we wouldn't go anywhere else because of him. He's fair, responsive, and a straight shooter that will work with you. Replacing a roof isn't cheap, so when we saved up the money we called him and he worked within our budget and time frame. His team showed up on time and just went to work. They were very diligent throughout, including their clean up effort - which was spotless. Beyond the work of the team putting on the roof - Springfield sends their own in house inspector to double check the work afterwards, someone completely separate from the first team just to make sure everything is done, and done right. Gives us a lot of confidence that we made the right hire. And although we know we won't have any roof needs in the near term, we will always have Mike Bennett on speed dial. Great job, thanks Mike and Springfield Roofing!"

"From start to finish, WE Griffin Roofing did outstanding work. An important aspect as that they are both a roofing company as well as a gutter company, and in our case both sets of expertise were needed. We obtained three bids, and decided to choose WE Griffin because Matt Hoffman gave us such an insightful analysis and estimate of the work needed. We had purchased this house (a 1962 split level) last year, and the gutters were literally falling off their fascia boards and also the fascia boards were coming apart as well. Mr. Hoffman diagnosed that potentially extensive roof repair would also be required, including both the rafter tails as well as the sheeting under the shingles near the edges, and including that work in his estimate along with the gutter and trim replacement. His estimate of the work needed turned out to be very accurate as many of the rafter ends and a whole section of sheeting on the back side were rotted and needed repair/replacement. The crew was similarly excellent; they arrived on site as scheduled and worked tirelessly for nearly 4 days to do all the repair work, replace all the fascia boards, replace some of the missing cladding that had also come off in places, and install a complete set of new gutters. Each day when the crew left they tidied up the site very nicely, and at the end of the project the yard was completely clean. They worked very carefully with a lot of attention to detail. The outcome is that we now have gutters as well as fascia boards and cladding that all look spectacular! We are very pleased with their work."

"A previous roofer could not stop the leaks coming from one of our skylights. Dan from Central Exteriors did an excellent job diagnosing the problem and fixing it. I highly recommend Dan and Central Exteriors for your roofing needs."

"We were convinced to have our roof done after the roofing expert inspected our roof and sat us down for his presentation. We appreciated the time spent to explain the project management plan from the delivery of materials to the post-installation inspection. Everyone we met was very professional and the clean up crew did a great job."

"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."

Roofing questions, answered by experts

The proper specifications for furring strips can vary, so you should always consult the roofing manufacturer's guidelines or your roofer. However, general recommendations are as follows:

  • Thickness: Furring strips are typically 1 to 1-1/2 inches thick, meaning standard 1-by or 2-by lumber works well. In areas with extreme winds, a thinner strip may be preferred to limit how much air can get under the roof and cause uplift. A thicker strip can add slightly more insulation but will also increase installation costs.

  • Spacing: The recommended spacing for furring strips is between 12 and 24 inches apart on center. Proper spacing is crucial for ensuring good airflow, adequate drainage, noise reduction, and better energy efficiency. The ideal spacing can depend on the roof's pitch and the specific type of metal roofing being installed.

The level of underlayment’s water resistance will depend on the type of underlayment. The most popular underlayment, felt, is water-resistant, but it can’t withstand long direct exposure to rain or the elements. 

Synthetic underlayment is more waterproof, but asphalt is the only fully waterproof type of underlayment.

The placement of snow guards depends on the individual roof, but typically snow guards are placed between 12 and 18 inches from the eaves, though they can be placed as close as six inches and as far as 24 inches from the eaves. A roofing professional can assess the roof and potential snow loads to determine the best placement.

No, you should not close or cover your gable vents in the winter. While it might seem logical to block cold air, heating your home creates hot air that rises and can cause condensation in the attic. If the vents are covered, this moisture becomes trapped, creating an ideal environment for mold and mildew. Keeping the gable vents open ensures proper ventilation, which helps dry out the attic, maintain even temperatures, and prevent moisture-related damage.

The most common slope range for roofs on houses in snowy areas is between 4/12 and 6/12, or 50%. A roof with a slope of less than 10%, or roughly a 2/12 pitch, won’t be effective at shedding snow. However, roofs that are too steep can allow large amounts of snow to build up and fall all at once, creating a hazard for those on the ground.
