Housing Tip of the Month -- September 2000
Roofs
September 1, 2000 -- The most common roofing material used in single family housing
construction is the asphalt shingle. Asphalt shingles are available in various styles and
life expectancies. Life expectancy is gauged by years and generally ranges from 20 to
35 years. When purchasing shingles or receiving quotes seek advice from a reputable
contractor. Compare the costs between a 20 to 25 year shingle and a 25 to 30 year
shingle, the difference for the additional 5 years may be minimal and money well spent.
Roofing contractors are not always required to be licensed with the local municipality.
Larger metropolitan cities may require licensing while smaller and rural communities
may not. You should inquire with your local building department to determine if licensing
is required before hiring a contractor. It is wise to consider the following four issues
when hiring a roofing contractor:
1. Liability Insurance
2. Status of Applicable License
3. Workman's Compensation Insurance
4. Warrantees on Workmanship
Installation of asphalt shingles on a pitched roof usually includes flashings, eaves
protection, starter strips and ventilation of the attic. Stripping of the old deteriorated
shingle is recommended to ensure the new shingle is installed over a smooth, solid
surface. Stripping the old shingle also gives you an opportunity to inspect the roof
decking for rot and decay and to make required repairs. Unrestricted ventilation at
soffits and ridge areas is critical in maintaining the proper life expectancy of your roof.
The contract should also address cleanup and removal of waste, protection of
landscaping and shrubs, magnetic sweep of grounds for stray nails and an allowance
cost for additional plywood or decking needed after the roof is stripped. All these
conditions should be outlined in a good, clear, descriptive contract with your roofing
contractor.
