How can I prepare my home for re-roofing?
INTERIOR:
Vibrations
(primarily hammering) may shake items off your shelves or walls. To
safeguard your pictures, plates, figurines, etc. we recommend that
customers remove valuables from the walls and shelves until our work
has been completed.
EXTERIOR:
We ask you to please remove any portable items (i.e. potted plants,
patio furniture, toys, etc.) located near the perimeter of your home
before our arrival. If you have special concerns, (i.e. flower beds,
bushes, driveway space, etc.) please bring them to our attention before
we begin and we'll be certain to address them.
Finally, due to the novelty associated with roofing, and the heights at
which we perform our work, it's no surprise that our efforts attract
the attention of onlookers. For safety reasons, we ask that you
instruct your children (if applicable) to stay clear of the work area.
How long will it take to complete my re-roof?
Depending on the size and complexity of the job and the agreeability of
Mother Nature, an average roof will take 4 to 7 days to complete.
Items of complexity that come into play would include the following:

Are
the materials required for the project successfully loaded onto the
roof? Some houses may have restricted access to the roof as a result of
trees, fences, landscape issues, the pitch of the roof, power lines,
etc., which affect our abilities to load the roof quickly and therefore
prolongs the completion.

Are
there any roof deck repairs to be done? Once the original roofing
material has been removed, the examination of the roof sheeting is
inspected to ensure it is sound for a new installation. If it is not,
it will be replaced and the completion of the re-roof will take longer.

What kind of
roofing materials were used on the previous shingle installation? The
removal of the existing
roofing material also plays a part in our
timeline. For instance, cedar shakes take longer to strip, clean up and
dispose of than asphalt shingles.

Finally,
Mother Nature plays a large role in our completion schedule. We do not
want any unnecessary water damage to your roof deck, which means our
work is stalled during rainy days.
How do you get the materials you need on to the roof?
Our suppliers have large flat bed trucks that are equipped with one of
two systems that allow them to load the product on to your roof. Our
suppliers will determine how to load the roof based on your homes
placement in relation to the public road ways and any other
complexities that may block the roof access. In some cases, the
suppliers will place plywood on your lawn and back into the yard to
gain the necessary reach for loading the shingle bundles. Either a
conveyer belt system or a hydraulic arm will then be used to hoist
shingles on to the roof. They will spread the bundles over the peak to
ensure that the weight is distributed equally and there is no
unnecessary stress to the roof.
What causes ice damming?
Ice damming occurs when heat from the roof melts the snow. The water
then freezes when it reaches the cold eavestroughs. As a result, ice
builds up at the eaves and creates a dam that traps water. Heat that
causes the snow to melt can come from the following:

Inadequate
insulation that allows excess heat into the attic.

Improperly
sealed bathroom fans, attic hatches, and light fixtures, which allows
heat into the attic.

Insufficient
ventilation. Ventilation is needed to exchange warm and moist air with
cold and dry air.
What is Ventilation?
Ventilation is the process of supplying a continuous supply of air
through the attic space. Proper ventilation consists of 50% intake and
50% exhaust, which lies near or at the roof peak. The exhaust should be
at least 3 feet higher than the intake system.
Why should I ventilate my roof?
Ventilation is used to help protect your roof from heat and moisture.
Heat in unventilated attics may cause temperatures to exceed 150
degrees, which can cause damage to shingles. Moisture can cause rot,
mildew, mold, paint blisters, and can cause insulation to become
ineffective. Proper ventilation can reduce energy bills, prevent ice
build up and eliminate mold and mildew.
How many vents should my roof have?
Requirements for ventilation are 1 sq ft of free air movement per 500
sq ft of attic area. On pitches less than 4/12, the required
ventilation doubles. Generally, 1 vent per 500 sq ft on pitches of 4/12
or greater is required and 1 vent per 250 sq ft on pitches less than
4/12 is required.
Is this repair covered under my warranty?
Any problems in workmanship that appear within 10 years of the
installation will be repaired at no cost. Damage caused by high winds,
animals, or natural disasters are not covered by warranty. Defects in
material are covered under the manufacturers’ warranty.
