Age of the Roof        

What is the age of the roof?

A simple question.... and the simple answer is this- If the asphalt shingle roof is more than  25 years old you should plan on replacing the surface.

Warning!!-- Rules of thumb are useful however the guideline for the Northeast Climate must be balanced with the physical condition of the roofing material. 

I once inspected a house that was 48 years old and the steep sloped roof
surface was covered with the original layer of roofing. The roof had about five more years 
of remaining life. The roof shingles were fabricated from a superior grade of material, 
was properly installed with good attic area ventilation, and the roof surface had a steep pitch.

See Normal Life Expectancies, 
the Roof Photo Gallery
and the discussion below 
for additional information.


Although this discussion is limited to asphalt shingles there are other types 
of roofing materials that will be discussed.  Some of the other materials are: 
roll roofing, slate, wood shingles, metal roofing, and clay, asbestos, 
composite, and concrete tiles.

Most homes have a sloping roof surface that are covered with asphalt shingles.  
Briefly, asphalt shingles are constructed using either an organic base material 
or a fiberglass base. Fiberglass (Fiberglass shingle) being the newer technology.  

Asphalt shingles are attractive (available in various colors and styles), 
durable (material warranties ranges from 20 to 40 years), 
and comes in various fire rating classifications.  

Is the roofing on your dream home inferior, average, or superior in quality? 
When  evaluating  a roof, look for the physical condition (tell-tale-signs) that will modify 
the short answer of -If 25 years old, replace the roof.

Tell-tale-signs that the roof is worn:

  • Numerous water stains on interior walls and 
    ceilings directly below the roof surface.
  • Excessive moisture or humidity and/or a damp odor in the attic area.
  • A number of missing, broken, and/or torn shingles.
  • The roof shingles are curling or buckling.
  • The mineral shingle surface is worn, pitted, blistery, or missing in sections.
  • Surface cracks and/or a dry/brittle appearance.
