Review our Questions/Answers for responses to frequently asked client questions.

Can you install a new roof in the rain?

Manufacturers recommend that shingles be installed on a dry surface. However, the moisture that may be present on the felt surface will evaporate in time as the felt serves as a moisture barrier between the shingles and the roof deck.

How do I know when I need a new roof?

When inspecting shingle/composition roofing look for granual-loss that may accumulate in the gutters. As the roof ages you may notice that the edges of the shingles start to curl or split. The asphalt leaching out of the shingle over many years causes this.

What is the difference between 15# and 30# felt. l

Fifteen pound felt is the minimum requirement for shingle underlayment. Thirty pound is twice as thick and is used to smooth irregular surfaces like most recover jobs. Because the plywood underlayment is older we tend to use 30# felt on our tear off jobs.

What are the biggest causes of roof deterioration in the Mid-Atlantic?

The biggest causes of roof deterioration in the Mid-Atlantic range from moss, high winds, and old age of roof. In roofs with low sunlight Moss attaches itself to organic matter like debris and even the asphalt itself. As it grows, the minute root system weaves its way down into the shingle, which causes the shingle to separate.

Why don't the rows meet all the way around the house?

All types of roofing materials are started at the eave line and worked to the ridge. Certain materials are adjusted at the ridgelines to give the appearance that all courses are the same. This adjustment prevents the courses from lining up.
