Mold grows indoors when spores in the air land on wet surfaces caused by roof leaks, plumbing problems, ventilation issues, and other moisture sources.  Molds produce allergens and in some cases toxic substances that can cause reactions in people with allergies and asthma.  Mold spores grow when moisture is present so keeping your home dry will prevent a problem in the first place.  After cleaning up mold, if the water problem isn't solved, mold will return.  It is important to accurately assess a mold problem and have clean-up and moisture problems handled professionally.

Shingles are the most common type of residential roofing material.  

Asphalt shingles are the less expensive than the other options like wood, slate or metal materials.  Shingle roofing need very little maintenance and therefore a low maintenance cost.  They are easy and inexpensive to repair.  Asphalt shingles are durable and long-lasting with many warrantied for 30-50 years.

Shingles are treated to be waterproof and keep moisture away from your roof structure.  This material is sturdy and flexible enabling it to fit many roof designs.  They are lightweight and suitable for almost any home structure.  Fire-resistant shingles help to protect your home.

Shingle roofs are easy to install.  A professional roofing contractor can install a new roof in just a couple of days.

Shingles come in a variety of colors, textures and designs.  The most common is the 3-tab design.  New architectural designer styles have a two-layer dimensional appeal and can mimic the look of other roofing materials.  There is a shingle look to match any home.  Click here to try some out with the Owens Corning® Design tool.

One item that should be included on every roof replacement estimate is underlayment.  Underlayment is a layer of protective material between the roof deck or plywood and the shingles.  Often called felt paper, it is the first layer of waterproofing for your roof.  

In addition to the standard felt paper there are new types of underlayment.  Some manufacturers reinforce the underlayment with fiberglass to strengthen and resist tearing, make installation easier and improve its waterproofing effectiveness.

Manufacturers are constantly developing new underlayments.  Newer synthetic underlayments further increase the effectiveness of and ease & safety to install underlayment and increase longevity.  Some manufacturers have developed organic and green underlayment products.

It is usually recommended to use underlayment from the same manufacturer as your shingles as they are designed to work together and it may be required for a valid warranty.

A contractor will choose the best type of underlayment for your roof replacement based on the type of roof and climate in which you live.  If you have any questions regarding their choice, they are the best resource for your specific project.
