Sometimes. Professionals may be able to remove the old roof and re-attach it when completed, depending on your blueprints. That can help you save money. But this method is not without its risks. Larger roofs may crack during the transportation process. And if the roof is old or has problems, it may be better to replace it entirely. Keeping the old roof isn’t always possible if you are making significant alterations to the roofline.

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.

Ideally, you shouldn’t pay your roofer upfront unless you’re special-ordering materials. However, anything between 10% and 15% of the project’s cost is reasonable to pay upfront. Avoid making a final payment until after the roof gets completed.
