remain the most popular type of residential roofing because of the
affordability, durability and aesthetic appearance. Roof
installers in St. Peters MO know some of the
more interesting details about these shingles that most people aren’t
For example, not
everyone realizes that shingles can be recycled. They may view metal
roofing as a more environmentally friendly option, but asphalt
shingles actually can be used in the process of making new asphalt
for pavement. One ton of recycled shingles allows asphalt
manufacturers to avoid using one barrel of oil.
The shingles placed by roof installers in St. Peters MO are not made entirely of asphalt. Technically, they are called composite or composition shingles because they contain more than one component. The bottom of the product is usually made of fiberglass. This material is coated with asphalt, after which ceramic or stone granules are applied. Those granules are what people occasionally see at the bottom of downspouts or in the eaves troughs when they clear out the leaves.
were invented in the early 1900s, but they were made of cotton felt
paper instead of fiberglass. Fiberglass shingles did not come on the
market until the 1980s. Roofers call the original invention organic
shingles. It is still possible to order those shingles, and many
homes have them on the roofs from installation back when this was a
more common option.
When a shingled
roof leaks before it needs to be replaced, those leaks usually occur
because the flashing around one of the roof features has been
affected by weather. That might be flashing around a chimney or a
skylight, for example. Sealing must be done as recommended to prevent
leaks from developing.
It’s possible for some customers of a contractor like Affordable Exteriors to have a second layer of shingles placed over the original if a full roof replacement would be a financial hardship. This process, known as reroofing, allows them to delay having the old roof replaced for many years. This is not the optimum decision, but it will end leaking in worn areas of the roof.
