The average lifespan of most roofs is between two decades
and 25 years. Some signs that you are due for a new roof installation may
include old rood, damaged chimney flashing, roof leaks, and sagging roof. You
have decided to install a new roof, selected a reputable and licensed roofing
contractor and purchased the roofing materials. The roof replacement or
installation can take a couple of days to complete, depending on the home size.
Part of preparing for roof installation is removing wall decorations,
relocating vehicles and pets, and talking to your neighbors about the noise.
Here is a breakdown of the things to expect during a roof installation or
The Tear Off
The first step when replacing an old roof with a new one is
tearing off the old one. It’s not advisable to add a new roof on top of the old
roof because it ultimately damages the roof’s structural integrity. Your
roofing contractor will tear off all the old layers and rebuild them later.
Tearing off an old roof is a risky job that you should leave to the experts.
When the contractor removes the old roof, look out for falling debris that
could damage your property. Occasionally, roofing contractors use tarps to haul
A Roof Evaluation
Once the contractor removes the old roof, they then inspect
what has been left behind. Roof sheathing is left after tearing off the old
roof, and it supports the new roofing materials. The contractor inspects the
roof sheathing for any damages and repairs or replaces it before the roof
installation. Depending on the type of roof the contractor is installing, your
roofing contractor might replace rotten wood with new plywood or sheathing
Install Protection against Weather Elements
Once the roof deck is ready for installation, the contractor
then installs ice, underlayment, and water shield to protect the new roof from
water damage. The systems used to waterproof the new roof will depend on the
climatic conditions in your area. If your area experiences heavy rains, ice
dams, and storms, it’s best to use a system that will shield your roof from any
water damage and winds. The contractor installs the water barrier around the
roof edges to prevent leaks and further damage.
Install the Drip Edge
After installing the water barrier, your roofing contractor
adds an extra layer of protection from water damage and leaks. The contractor
does so by adding a drip edge to your roof’s bottom layer. The roofing
contractor installs the drip edge on top of the water barrier to prevent water
from getting to the roof siding and exposing it to leaks.
Installing the Roof Underlayment
The roofing expert then chooses and installs the roofing
underlayment. It’s manufactured from water-resistant materials, and it’s
available in two degrees of thickness. Your roofing contractor will help you
choose the ideal thickness and choose between synthetic and felt paper
underlayment. The roofing underlayment is rolled along the roof’s edge and secured
with cap roof nails. Ensure that the roofing contractor installs the roof
underlayment correctly to protect the new roof from strong winds and heavy
Installing Roofing Shingles
The roofing underlayment is given enough time to dry and
secure properly. The next step is installing roofing shingles. After installing
the shingles, the roofing contractor paints all the roofing vents and pipes to
match the new shingles.
Once the roof installation process is completed, the next
thing is to remove all the debris from your property. The professionals use a
magnetic rake to pick up nails, staples, and other metal objects. The final
cleanup is an essential step because it leaves your home free of any hazardous
or harmful materials.
Roof installation is an important step and a huge
investment. Therefore, understanding the above aspects of the roof installation
process helps you to prepare. Call licensed and experienced roofing
professionals for a smooth installation and durable roof.
