Roofing systems require certain elements to protect the structure and interior of your home adequately. There are different layers beneath the Tiles, shingles or flat roof surface material that work together to form the roofing system and keep it functioning properly. When repairing a roof, roofing experts inspect the roof as a whole, not just visible damage.

Different types of roofs require different maintenance. Roofing experts in South Florida face unique challenges with roof repair and upkeep because of the hurricanes that can cause damage yearly. Roofs in Florida must stand up to high winds and rain.

Components of a Roofing System

The necessary parts of a roofing system include:

  • Decking Boards or Sheathing

    Decking boards are the sheets of wood that lay on top of the rafters of your home. They form the foundation of your roof and are strong enough to bear the heavy load of the roofing layers above it. Over time, this wood can weaken or warp especially if there is damage to other roofing components. Also, if you haven’t insulated your attic well, heat and moisture accumulate under the decking board and can cause issues from the inside out

  • Base Sheet

    This layer is the first layer that is laid over the decking board to seal the roof. It is required, and it serves multiple functions.

  • Underlayment

    This is a water-resistant material that is installed over your base sheet. It is applied as an added layer of protection from severe weather. There are different types of roofing underlayment for sloped roofs such as 90LB. felt, tile cap sheet and modified bitumen which is installed with hot asphalt, self-adhered underlayment For flat roofs there is different fiberglass ply sheets which can either be hot mopped or mechanically fastened and self-adhered.

  • Flashing

    The metal or modified sheets placed at joints on vertical walls, around your vents, skylights, chimney and valleys is considered roof flashing. The flashing diverts water from areas such as valleys, hips and returns where it may accumulate. Flashing can be made from many materials buts it’s typically made from some type of metal such as galvanized, aluminium, stainless steel or copper. Common problems with flashing include buckling, penetrations, or loosening. When these instances happen, water can invade the interior of your home.

  • Gutters

    Gutters perform a similar function to flashing. Their job is to collect water from the roof and divert it to an area further away from your house via downspouts. Gutters require upkeep. You must clean them regularly, or they’ll clog and sag. Gutters can also cause the roof to rot by pushing water back on to it instead of getting rid of it.

  • Shingles and Tiles

    Shingles and tiles make up the outer layer of your roof, and they are installed over the underlayment. These roof components are the first thing that you see from the street. Common roof types in Florida are shingles or tiles. These roofing styles have been around for centuries, and people have even discovered intact tiles from 5,000 years ago. Shingles and tiles are the first line of defence as they protect your home from hail, high winds, hurricanes, debris, rain, and more. However, tiles can crack, shatter, fall off and shingles can rot, erode, curl, or blow off depending on how old the roof is and the materials that were used to construct it. Asphalt is one of the most common materials that shingles are made of and cement for tiles.

  • Vents

    Vents are unique metal constructions the keep moisture from being trapped under the roof. They help moisture escape and protect the roof from rotting or producing mold. Roofing vents can become deformed or rust, and as a result, their functioning fails.

  • Fascia

    Fascia is the vertical wooden pieces that outline your roof creating finished edges. The fascia functions as a connecting point for your house’s gutters. Fascia can warp of rot allowing water or pests to enter your home.

  • Soffit

    The soffit connects the overhang of your roof to your house. As soffits age, they can stain and decay. As a result, they need to be repaired or replaced by a professional to keep your home pest-free and dry.

Commercial and residential roof repair and maintenance are critical to the infrastructure of your home or business. Your roof performs a vital function to protect your building or home from the top down. If you think that there is any damage to the components of your roof, call a roofing professional to inspect and repair any problems.
