If
your house is typical, its roof is covered with asphalt
shingles, which may need to be replaced every 15 or 20
years. Temperature extremes and sunlight can crack,
curl, and split the shingles. Rain and sleet wear them
down. Wind tears them.
Although
Pittsburgh homeowners may select the type of roofing, they usually
leave the brand to the roofer, and that may be unwise.
Even experienced Pittsburgh roofers are apt to judge quality by two
seemingly sensible but not always reliable criteria:
weight and warranty. Warranties on asphalt shingles
typically run from about 20 to 40 years, but that's not
as generous as it may seem. Generally, the warranty
covers both materials and labor only for the first year.
After that, the cost of labor may be excluded, and the
cost of the shingles is prorated, sharply reducing the
warranty's payback over the years. Some warranties are
transferable, a consideration if you're planning to
sell, or buy, the house. But some manufacturers charge a
transfer fee or reduce the coverage sharply. Many won't
transfer the warranty at all. Check when you choose a
brand.
