Why is the proper ventilation of a roof important?

It is important to have a properly ventilated roof to remove the condensation and excess moisture in the attic.  Too much moisture inside the attic may leak inside a home even if the roof shingles and decking are sound. Also, ventilation extends the life of roofs, reduces energy costs, and prevents temperature differences inside one’s home.

What is ridge venting?

A ridge vent is a vent that is installed at the peak of a sloped roof.  Its purpose is to help keep the air inside your attic as close to the outside temperature as possible.  It does that by allowing warm, moist air in your attic to escape. The right combination of ridge vent and continuous flow soffit vents provides proper ventilation.

Although code does allow for an overlay of one layer of existing asphalt roof shingles, in many cases, we do not recommend it.  With a tear off of old materials, we can look for any structural damage that may have occurred due to storm damage, or age or both. If there are any defects in the roof deck like rotting, this would be revealed during tear off.  Also, starting with a clean deck, with fresh underlayments, results in a smoother finished roof system. That being said, there is a stone coated steel shingle that does work well with an overlay Read More >

Do I need a new roof?

If your roof has been properly installed, ventilated and periodically inspected it should last around 20 plus years, give or take.  If you see curled or cupped shingles, cracked shingles, exposed nails, worn off granules, holes, missing shingles, leaks in your roof, or storm damage it is time to plan for a new roof.
