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.
