Peterson RoofingQuestions

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.

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

condensation 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

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.

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

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.

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

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?

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

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

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.

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.
