Welcome to Dunn Contracting Roofing!

Asphalt roof shingles are designed to  last from 15-25 years depending on the type. Under normal circumstances  they do achieve their anticipated life, although there are some common  factors that can cause a roof to fail earlier.

We also inspect the attic if needed:

•  Look for signs of water damage and leaking.
  
•  Look for dark spots and trails.
  
•  Look for signs of outside light.
  

We also inspect the exterior of your roof:

•  Look for damaged or missing shingles.
  
•  Look for excessive amounts of shingle grain in the gutters.
  
•  Look  for signs of moss build up Splits: Shingles that are split or cracked  can be signs that more than just shingle damage is taking place.  Improper attic ventilation can be the culprit behind cracked and broken  shingles. Be sure your roofing inspector checks attic ventilation when  inspecting your roofing system. 
  
• Composition Shingles: curling, loss of granulation, broken, damaged or missing shingles
  
• Flashing: tears, buckling around roof penetrations
  
•  Roofing Cement: excess cement, crumbling    Soffits and Fascia: decay, stains
  
• Soffit & Ridge Vents: clogged or damaged vents, flashing and shingles around them curling or missing shingle tabs

Your  flat roof is one of the most important and perhaps most overlooked  component of your home or building. As they say, ‘out of sight, out of  mind,’ and this is commonly the case when it comes to flat roof  maintenance. This often leads to building owners overlooking the  importance of having their roof inspected regularly.  

 Inspection  of building roof systems will lead to early detection of roof problems.  We inspect and report report signs of roof damage, structural anomalies  and/or leaks. We also look to determine if the roof system is  performing according to its intended function and identify needed  repairs. We will also answer any questions and Include photographs of  any problems  

 Flat roofs are  low-slope roofs. Low-slope and steep-slope roofs have different  requirements. “Pitch“ is the term used to describe the degree of roof  slope. Flat roofs have one slope but very little pitch. A typical pitch  would be ¼-inch per foot..  

What we look for during our inspection: 

Alligatoring: Shrinkage cracking of the bituminous surface of built-up or smooth  surface roofing, producing a pattern of deep cracks resembling an  alligator hide.  

Blistering: A spongy raised portion of roofing membrane as a result of pressure of entrapped air or water vapor.  

Cracking: A break in a roofing membrane as a result of flexing, often occurring at a ridge or wrinkle.  

Fishmouths: An opening of the lapped edge of applied felt in built-up roofing due to adhesion failure.  

Ponding: The collection of water in shallow pools on the roof surface.
