Tear off or not?
Your shingled roof is very often overlooked until a problem
occurs. When a new roof becomes  necessary, consider the
options, as well as the criteria used to determine which
system your roof is a candidate for.

Your existing shingle roof must be torn off if any one of 
these conditions exists.

1.) Your roof has two or more layers.

City codes require that at least one later be torn off, 
depending where you live. Most cities allow only two
layers on your roof. Usually when you tear off your existing
roof it is best to tear off all layers and is required in 
most cities.

2.) Your decking has rotted wood as evidenced by 
soft spots, or the roof will not hold a nail.

3.) The shingles on your roof are excessively curled or buckled.
If so, yo
ur shingles are probably starting to fail.

Your existing roof will be considered for re-roofing over the
existing roof
if it meets the following criteria.

1.) The existing roof has one layer.

2.) Your shingles are free of excessive curls and buckles.
3.) The roof shows no evidence of rotted wood.

Any visual flaws on the existing shingle roof will be exaggerated

by re-roofing. Any dips, buckles or bumps will look larger with
another layer of shingles on them. A re-roof  costs less than a
tear-off, but a re-roof seldom look as good as a tear-off.

What's the difference in asphalt and fiberglass?
All composition shingles are made with asphalt.
The difference is the mat, which is inside of the shingle.
The mat  holds everything together. Inside of a "fiberglass"
shingle there is a spun fiberglass mat and inside an
"asphalt" shingle there is what is called an organic mat.
The organic mat is very similar to  a piece of cardboard.
Both types of shingles are made with asphalt, the difference
is what the asphalt is attached to.

     Does it matter which color I choose?
There is a difference in the amount of heat that a
dark shingle will absorb as opposed to a light colored
one. Dark shingles absorb more heat, thus transferring
more heat to your attic space. Light colors are just
the opposite. There is a train of thought that says...
Your dark roof absorbs more heat so it will wear
out sooner. It is my belief that the quality of the shingle
is the most important factor as to whether the roof fails
prematurely or not. To deal with the heat transfer to your
attic, from darker shingles, you must have your attic
insulated and vented properly, thus keeping the attic air
temperature as close as possible to the outside air
temperature. The answer to which color to choose...
Make sure you have adequate ventilation and insulation
and choose a color you like!

What are those square things I see on roofs?
Those square things, sometimes round spinning things,
are air vents. There is also a type that is called "ridge vents"
that are not as noticeable. Also there are attic power vents
that kick on and expel the air when it reaches a determined
temperature or humidity level. Ventilation is very important
to the life of your roof! If your attic space gets too hot, the
heat, not only transfers down into your nice air conditioned
living room, but it also builds up in the attic causing the shingles
to get to hot from the underside, thus they will "dry out"
prematurely. It is also important to have vents in your
soffits or eaves and up towards the peak of your roof. This
causes the air to move passively and won't allow heat buildup.
Also the movement of air in your attic can help prevent
during extreme cold outside air temperatures.
During cold snaps
the cold outside air mixes with warm moist
air that escapes
from your house through attic access doors,
bath vents, poorly insulated ceilings, light fixtures housings,
and numerous other ways, causing moisture and frost in your

attic space. It is very important to prevent conditioned air
from entering your attic space! Excess humidity in your home
is not desirable! Also proper venting and insulating help

prevent ice dams. Ice dams can occur when it is well below 
freezing, but the snow on your roof still melts rapidly.
The warm
air escaping from your house melts the snow.
The melting snow re-freezes
when it reaches the overhangs
of your roof where there is no warm
air from your house to continue
melting the snow, causing an ice
dam to form higher and higher.
 A compounding problem!


Which shingle do I choose?
Good question. There are so many I have trouble keeping
up with them myself! The main thing is choose a shingle that has
at least a 30 year warranty. Also in the rare instance you have a
problem with your roof, you want a company that will stand
behind it. We use shingles made only by quality manufacturers.
There are standard 30 year shingles, dimensional
shingles, also called laminated or architectural shingles or
simulated wood shake shingles and many "designer" shingles.
The dimensional shingles have a rougher look and generally
come with a better warranty. There are 30 year through
lifetime warranties in the dimensional shingles. The weight
of the shingles usually go up accordingly with the length of
the shingle warranty. There are wood, slate, simulated slate,
concrete, metal, clay tile, simulated clay tile, WHEW!
The list goes on and on. Now days, most home owners choose
 30 year laminated shingles. If you have a reputable contractor
install your new roof he can help you select the right roof for you.

How do you clean up and dispose the old roofing?
Before we begin tearing off we take precautions to protect
the landscaping by covering everything in harms way with tarps.
We either lay tarps on the ground or stretch them down off the
roof and over your landscaping. Some times plywood is leaned
against the house for added protection where needed.
On roofs that are easily walked upon, we tear off and carry the
old shingles to the spot where the truck or dumpster is parked
and toss the shingles in! Very little debris ever hits the ground! 
If the job takes more than one day to complete the site 
is cleaned daily. When the work is completed we do a final
thorough cleanup. We run a magnet through the yard
and drive way to get stray nails, rake up the smaller roof particles
and clean out the gutters. Things the homeowner can do
to help are, Make sure the grass is mowed, make sure leaves are
raked so stray nails don't nestle down in them. Have bushes and
trees trimmed for easy access to your roof. We know you take pride
in your home and we will too.

What can I do to prepare for the roofers ?
A number of things can be done to prepare before the job begins.
1.) Mow the grass and rake the leaves.
2.) Trim bushes and trees away from house if possible.
3.) Remove items on the walls and shelves if you think they are not secured properly.
4.) Cover valuables that may be in the attic.
5.) Remove vehicles from the garage and driveway.
6.) Let us know where a power outlet can be found and make sure it works.

Will there be any dust or debris in my attic area?
Yes. In all roofing jobs, some of the finer grit will fall between the 
cracks of the plywood or plank board decking. In cases where 
a vent system is installed, saw dust will fall into the attic. 
We suggest removing or covering any items stored in the attic 
space if dust or debris accumulation is a concern. 

Should I protect items inside my house from damage?
Yes. On all roofing jobs there is a degree of vibration which comes
down through the framework of the home. While it is not necessary 
to panic, it is recommended you safeguard fragile items such as 
glass globes on chandeliers, pictures which are not securely 
mounted to the wall, or the "old family heirloom" on the mantel.
Items in the kitchen cabinets should not be affected, nor should 
there be a need to empty the china cabinet. If in doubt, take a 
few minutes to protect any non-replaceable items.

When should I replace my roof?
Most composition roofs last 15 - 30 years depending several factors.
How long of a warranty did the shingles come with,
how well the shingles were made, and how steep is the roof. 
(Steeper roofs last longer). Signs that your roof needs replaced are...
excessive granule loss that exposes the asphalt, (granules show up 
at the bottom of your down spouts), shingles blow off during wind 
storms more frequently, cracked or brittle shingles, curling shingles 
and a leaking roof.

Do I need to be home to get an estimate?
The short answer is no, but it is better if someone is home.
When someone is home you are assured that you will
get an estimate for exactly what you want, and it is easier
for us to answer any questions you may have. Most estimates 
only take about 15 - 30 minutes. Our representatives are not 
pushy sales people. Our representatives are trained to listen to
your needs, take all necessary measurements and give you an
estimate for what you want. Most estimates are given at the same 
time we are at your home. If you need an estimate for specialty
shingles or a custom order we will have an estimate for you
within a few days. We want your experience with Peterson 
Roofing to be a pleasant one, including the estimate.

How do I know if my contractor is reputable?
The simple answer is to ask around. Have they worked for any
of  your friends or relatives? Are they certified by Owens Corning?
Check with the Better Business Bureau, Chamber of Commerce,
or with the building department. Ask for  references or if they
have done any work in the neighborhood. 
They should be able to come up with a few references right away. 
They shouldn't require any money as a down payment. We hear 
stories time and again of home owners who give a deposit to the 
contractor and never hear from the contractor again! I know many
contractors seem to be "nice" people and very trust worthy but don't
hire a contractor without good credentials.

Will my insurance pay for it?
In some cases your insurance company will pay for a new roof.
Insurance will pay for a storm damaged roof, hail damage, wind 
damage tree damage etc. Many times we overlook our roofs after 
a severe storm and don't think about it until a leak appears. Your
roof could have damage from a previous storm that was overlooked. 
When in doubt it is best to call your insurance company and have 
them send an adjuster to look at the roof and advise you on the 
damage. Peterson Roofing works with most insurance 
companies and will do the required repairs specified by the 
insurance company, with no cost to you other than the deductible
amount of the policy.

How much will it cost?
Peterson roofing charges on a per 100 square feet or "square"
basis. Click here for a real time estimate. Many factors determine
the price of the roof. How steep, how big, how many stories, how
many layers need to be torn off, how easy is access to your roof,
what type of shingle, is there a need for wood replacement etc.?
The average 2 bedroom 1 story home, not steep, tear off 1 layer
and re-roof, 30 year shingle with easy access to the roof costs
around $5000.00.  We charge fairly and honestly with all our
customers and do not take advantage of any one. There are many
unassuming people who have the misfortune of hiring the first
contractor that shows up. The contractor, many times, is a high
pressure salesman that tries to get as much money as he can with
no regard for the various factors involved in estimating your roof.
Rest assured that Peterson Roofing will only estimate on a" per square"
basis and only for the work required. Peterson Roofing offers senior 
citizens discounts.

How long will it take?
Most  roofs take 1 to 2 days depending on the factors described 
above. The roof described above would take 1 day. A three 
bedroom house that is three stories tall with 3 layers of shingles 
removed and all new sheeting would take about 5 days. We clean 
up the job site daily if the job requires more than 1 day to complete. 
We remove only what we can put back on in the same day.
That way we don't have to worry about a storm overnight. 
Many inexperienced companies will tear everything off and
realize they "bit off more than they could chew". We see roofs 
all over town that have tarps needlessly hanging off them for
days and weeks. Tarps are not a sure fire way to keep out 
the rain overnight. A strong thunderstorm can rip a tarp to 
shreds if the tarp is not securely fastened down. Don't run 
the risk of having your roof torn off and left uncovered overnight!!

What kind of guarantee?
Peterson Roofing guarantees all new roofs in writing for up to 20 years. 
Most companies give 1 or 2 year guarantees or none at all.
We will guarantee to keep your roof in a watertight condition for up to 20 years.
We believe in service after the sale. If there is any thing we can do to help you
with roof concerns, we are here. Also, we keep very good records. 
If years from now you should sell your house and need information 
for the new owners we will have it. If you put a room addition
on your house and want to know what color shingle to match, 
we will know. If you have a problem with your roof, for any reason, 
beyond the guarantee period, we will still help you any way we can. 
Many contractors are looking for any way to get out of their
responsibilities. We will not let you go it alone even in the rare
instance of material defects. We are here to help. Remember a 
guarantee is only as good as the person that stands behind it!
