Metal roofs can affect service in a number of ways. They are more expensive than traditional asphalt shingles, so their installation costs may be higher. Additionally, metal roofs require special tools and materials for installation which can add to the labor costs as well. Metal roofs may also require specialized maintenance that isn’t necessary with other roof types. This could include resealing around screws to prevent water infiltration or repainting every few years to maintain the desired appearance and coloration. Finally, some municipalities have restrictions on what type of roof material can be used in certain areas due to fire safety codes or environmental considerations, so this should be taken into account when considering whether a metal roof is right for your home or business property.
