Signs you need
a roof replacement

Not every roof issue means a full replacement. We will tell you honestly whether a repair makes more sense. Here is what points toward replacement.

  1. Shingles are curling, buckling, or lifting at the edges
  2. Granules are collecting in your gutters or at downspout exits
  3. Your roof is more than 20 years old
  4. Multiple leaks appearing in different areas of the house
  5. Daylight visible through the roof boards in your attic
  6. Sagging or soft spots when you walk on the roof
  7. Neighbors on your street are already replacing their roofs after a storm
  8. Your energy bills have climbed without explanation

If any of these sound familiar, call (406) 313-3020.
We can usually diagnose in one visit.
