Frequently Asked Questions

  1. My roof is not leaking, so how will I know if my roof needs to be replaced?
    Answer:Look at the condition of the shingles. Cracked, dry, curling and or missing asphalt shingles or cedar shakes or shingles are a good indication that they are reaching the end of their useful life. Metal standing seam roofs will begin rusting and show signs of deterioration around the seams.
  2. Do I have to remove my old roof when I install a new roof?
    Answer:Code allows a second roof layer to be installed over a single layer of old roofing. However, if you have ice dams and leaks caused by backwater due to the ice dams then you will want to remove the existing layers of roofing so that an ice and water shield rubber membrane can be installed directly to the roof sheathing. (see “ice damage” below)
  3. I have ice dams that cause leaks in the winter, what can I do?
    Answer:Ice dams are caused when melting snow from heat loss through the roof, freezes on the cold overhang. Melting snow continues to occur and backs up behind the ice dam, creating a puddle of water that leaks into the house. Adding insulation and or proper venting can reduce or eliminate the heat loss that is causing the ice dams. If that is not practical then stopping the backwater leaks can be accomplished with the use of an ice and water shield rubber membrane. These products will self seal around the roofing nails and create a barrier that the backwater can not penetrate.
  4. What roof material should I install to stop the ice dams and backwater leaks?
    Answer:Stopping the leaks due to ice dams and backwater has little to due with your selection of roofing materials and everything to due with the proper installation of the roofing underlayment. An ice and water shield rubber membrane is the key component in stopping the leaks due to ice dams and backwater.
  5. How can I stop or control the growth of moss and algae on my roof.
    Answer:Many of the new shingles are algae resistant. Depending on your roofing materials, other methods of controlling the growth of moss and algae include the use of a zinc strip installed near the ridge or installation of a copper ridge cap.
  6. Will my new roof qualify for the Energy Star Tax Credit.?
    Answer:Currently (August 2009) the tax credit is for 30% of the material cost up to $1,500 for roofing, insulation, windows and doors combined. Roofing must be one of the new “cool roof colors” to qualify.
