Roofing Basics 101

Roofing terminology can be a bit overwhelming. These basic roofing definitions will help get your project off on the right foot.

There’s a lot to cover when it comes to learning about what types of materials go into roofing a house. Some of it involves some pretty tricky terminology. Here are a few definitions that cover the basics.

The major function of a roof is really to protect the home from the elements — snow, rain, wind, etc. And this is why you need a roof that really performs, and how it performs depends upon how well it keeps out the elements.

The type of roof you have will determine how easily water — or the other elements — are diverted. But before we get into the types of roofs, we need to know the different components that make up a roof.

Roof Components

Underlayment — The underlayment of a roof is the black paper that’s laid over the plywood sheeting in order to seal the roof from damaging elements (snow, rain, ice, etc.). The use of a membrane is typically required, a waterproof membrane, a sweat sheet or vapor barrier — with the underlayment paper serving the triple function.

Flashing — Flashing on a roof refers to the metal pieces that are used to divert water from places where it might collect, such as hips and valleys. Flashing can be made from a variety of materials. You can use a galvanized flashing, a galvanized alloy, copper, lead coated copper or stainless steel. Each of these would work fine.

Shingles or Tile — The shingles or tiles make up the outermost part of the roof. Sitting atop the underlayment, they form the outermost barrier against the elements.

In residential roofing the same basic types of roof have been in sue for hundreds of years are still in use today. The shingle — or tile — has been in use for thousands of years, in fact. You can find intact tiles that have been in use 5,000 years.

Despite their history, however, shingles and tiles are just two among many types of materials you can use to cover the roof. Others include concrete, wood shingles or metal.

Trim — The trim protects the seams anywhere there is a roof, such as a hip or a ridge.

The Seven Design Elements of a Roof

Ridge — This is the highest point or peak of the roof.

Hip — This is the high point where two adjoining roof sections meet.

Valley — When two sections of the roof slope downward and meet, they create this third element — a valley.

Pitch — This refers to the slope or steepness of the roof.

Eaves — This refers to the part of the roof that hangs over the rest of the home.

Gables — These are the triangular portions of the ends of the home, which extend from the eaves to the peak of the roof.

Dormer — These are the sections of the home that extrude from the roof. They’re usually added as a way to bring light into an attic or the upper level of your home.

Roof inspection Maryville Il


The following information is designed to assist owners in establishing a regular and beneficial roof inspection and maintenance program. This important area of responsibility for the building owner can provide many long-term benefits, including extended life expectancy of the roofing system, reduced average in-place cost, prevention of major deterioration resulting from minor problems and eventually, reduced roof system replacement cost.
Roof Maintenance Guidelines
All roofs require regular inspections and periodic maintenance to achieve their expected life. Roofs should be inspected at l
east twice yearly, in the spring and fall. Additionally, all roofs should be inspected after any severe weather or storms. The roofing contractor who installed
the roof membrane, inconjunction with the building owner’s maintenance personnel, should perform these inspections. Leaks occur most often at flashings, pitch pans, gravel stops, and other penetrations. Pay special attention to these areas.
Included among the roof components that are not part of the roof membrane and hence not covered by the applicable CertainTeed limited warranty are the
following: underlying roof deck, insulation, vapor retarders, fasteners, metal work, drains, pitch pans, expansion joints, skylights, vents, plastic accessories,
decorative or reflective coating, surfacing and/or any ballast, rock, or gravel. Roof components are the owner’s responsibility to maintain.
General
– One of the keys to avoiding roof damage is limiting access to the roof. Allow only authorized personnel on the roof who understand good roof
access procedures and precautions. Bag and remove all debris from the roof. Keep grease and oil off of the roof. Clean and remove any liquid deposits
immediately. Do not allow foot traffic on the roof in very hot or very cold weather. Do not allow the installation of television or radio antennas, satellite
dishes or other mechanical equipment without notifying CertainTeed for approval and for consultation about the methods and details for these installations.

How much will my roof cost in Granite City Il?

How much will my roof cost in Granite City, Illinois?

Day after day the question arises “How much will my roof cost?”

You can easily measure your roof from the ground and once you know the number of squares you can multiply by $250.00 to find the price of your new roof.  *This is including Landmark Certainteed shingles on a one layer 7/12 pitch roof or under*

1.

Measure the ground dimensions of the house using a tape measure, and write down these dimensions. Multiply the length by the width to arrive at the ground area of the house. If the house has an irregular shape, measure each part separately, figure the separate areas and add them together.

2.

Convert the area to roofing squares. Because each 100 square feet of roof is one roofing square, divide the total area from Step 1 by 100. The answer is the number of roofing squares for the roof.

3.

Estimate the pitch of the roof. Roofs have one of three pitches: low, medium or high. A low pitch rises 3 inches every 12 inches of base horizontal length. A medium pitch rises 6 to 9 inches every 12 inches of base horizontal length. A high pitch roof rises more than 9 inches for every 12 inches of base horizontal length. Estimate the roof pitch by sight or calculate it with a level in the next step.

4.

Calculate roof pitch by downloading a free app by pictometry on your mobile device.  Use the pitch gauge by lining the gauge to the roof line this will give you the pitch of your roof.

5.

Multiply the number of roofing squares for a low-pitch roof by 1.06 to 1.08 to get the square roof area. Multiply the number of roofing squares for a medium-pitch roof by 1.12 to 1.25 — or by 1.3 to 1.42 for a high-pitch roof — to get the square roof area.
