"Once I requested a quote, Nick respond immediately and come to my home at the scheduled time. He looked around and explained all the process involved in the replacement. He had bought with him all the material samples. He even gave me a approximate price when we met first time. I received the quote 2 days later ( as he had promised) and to my surprise it was lower than the approximate costs that he quoted me before. Nick quote beat the other 2 quotes I looked at and hired Nick for the job. The team arrived at the scheduled date and time and within 6Hrs the job was done. they cleaned all the debris around and left without any issues.. From start to finish, Nick and team did a great job.. The quality of material, labor and price is pretty good. I highly recommend Nick if you are thinking about replacing roof.."

"We discovered that the roof on our house was leaking. I called Sean at Scott Roofing service on Saturday. We had used them 2-years ago for another roofing project. I received a quote the very next day and was on the schedule for the upcoming Wednesday. The work crew was very friendly and completed the roof the same day. The quality of the materials and workmanship was at the highest levels. The work area was thoroughly cleaned to better than when they started. The dumpster driver was very friendly as well. When he picked up the dumpster he walked around the house with a nail magnet to be sure nothing was left. They are an organization of Master Professionals who I highly recommend."

"Sean and his crew replaced our roof yesterday. This entire process, from last November for the evaluation of the project, quoting and recommendation for Spring timing has been excellent. Sean is not only extremely knowledgeable but also is very friendly and has high expectations for his work. His crew is amazing, leaving our property spotless with an awesome new roof. We highly recommend Eaton Exteriors!"

Roofing FAQs, 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.

There are several pros and cons of flat roofs. One disadvantage of flat roofs is that you lose potential attic space because it's flat. Flat roofs tend to pool water and because they lack an angle, any leak in the roof—usually due to a bad seal—has the potential to let in a lot of water. They don’t work well in climates with snow. Flat roofs are also structurally weaker than sloped roofs.

In most cases and locations, roofs with a single layer of asphalt roofing shingles won't require roof removal before installing a metal roof. However, underlayment may be necessary on roofs with moderate shingle damage. Heavily damaged roofs or ones with multiple shingle layers will most likely require removal before a metal roof can go on.

Once framing is complete, you will need the following materials to roof a house:

  • Wood sheathing

  • Drip edge, a.k.a metal flashing

  • Underlayment for waterproofing

  • Roof covering, like metal or asphalt shingles

Generally, roof flashing is installed under the shingles to create a watertight seal and prevent moisture from seeping in and causing damage. However, the exact placement can depend on the type of flashing. For instance, with step flashing, the shingles and flashing overlap each other, meaning the flashing is technically both over and under the shingles. Flashing also typically goes beneath the house siding and is often not visible from the ground.
