"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."

"Excellent, finished and left no trace of being there within one day. Also despite being the largest roofing company of the quotes I received, they had the cheapest ones. Also gave you three different options with a checkmark table displaying the differences of what you are getting with each option. Thinking about calling them for my gutters. Professionals."

"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

Yes, capped chimneys should still be vented. Failing to vent a chimney will result in condensation buildup inside the chimney, which commonly results in mold growth. If mold begins to grow in a chimney, it frequently goes undetected and spreads quickly through the home. Mold and moisture can damage the structural integrity of your home, and exposure to mold can cause discomfort and illness in residents.

Tile roofing is durable, fire-resistant, and energy-efficient. It also adds aesthetic appeal and, with proper maintenance, can last 50-100 years.

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.

A roof's ability to handle snow depends on its strength and the snow's weight, as wet snow is much heavier than dry, fluffy snow. While designs in snowy regions often allow for 35 to 50 pounds per square foot, a general guideline is that a typical roof can withstand about four feet of fresh snow, two feet of packed snow, or just one inch of ice. Factors like the roof's age, slope, and support structure also affect its capacity; newer, sloped roofs generally hold more weight than older, flat ones. Ice and ice dams add significant, dangerous weight. Because capacity varies, it is best to contact a professional roofing contractor or the original builder to determine the maximum snow load for your specific home.

Roofing material costs vary depending on the type of material you choose and whether you install it yourself or hire a roofer. Shingles are the most affordable option and cost between $70 and $400 per square, metal roofing is between $100 and $1,500 per square, and concrete tile is between $300 and $1,000 per square.
