HOW ROOFING SHINGLES ARE MADE


Every day, thousands of tons of raw and manufactured materials are delivered to freight yards and receiving docks at top tier roofing plants across the United States.
These materials will be transformed into high QUALITY durable roofing shingles and specialty products that have earned the respect of countless industry professionals and homeowners.
Shingles made with asphalt as the main ingredient are the most popular shingles sold in the U.S.  today, and so the asphalt used at these roofing facilities is processed to meet the stringent quality requirements needed to create strong, yet flexible, shingles.
Limestone rock, which typically arrives at plants by truck or rail car , is processed by crushing mills into a fine limestone powder. This powder is then mixed with the asphalt to make a product called filled coating. On the production line, miles upon miles of rolled fiberglass mat that serves as the ‘backbone’ of shingles are rolled out and fed into a coater, where the filled coating – super-heated to more than 400 degrees Fahrenheit – is applied to the top and bottom of the mat to create a base sheet.
Next up come the shingle granules. Mined rock that has been sized for use as granules is put through a process where a specialty ceramic coating is applied. The coating is colored so that the granules create the desired shingle colors, and these granules are designed to maintain their appearance for the life of the shingle. A thin coating of sand is applied to the base sheet as it is fed into a press that embeds the granules. As the sheet loops through a series of rolls, a fine mist of water is sprayed onto it, and the evaporative effect of the water removes heat from the sheet.  Afterward, a strip of sealant is applied to the sheet in order to give the shingles protection against wind damage.
Complex cutting machines then slice the base sheet into individual shingles that are stacked and packed into bundles. Finally, the shingle bundles are wrapped in packaging, placed onto palettes, and then transported to warehouses prior to being shipped to homes just like yours all across America . ( CertainTeed )

Chimney Flashing

Posted by Robert Evans on Oct 13, 2014 2:59:00 PM

Chimney flashing

Chimney Flashing is a vital part of your roof. Robert Evans Jr. Contracting Inc. gets more calls about leaks around chimneys than about any other problem. And more often than not, the culprit is the flashing, the metal that keeps the intersection between the chimney and roof watertight.

Proper flashing around chimney includeds 2 layers. The first is called step flashing: L-shaped aluminum are woven into the shingle courses and lapped up the side of the chimney. Next comes the counterflashing: A second layer of metal usaully consisting of either Lead or Copper. {Most commonly used is Lead} It is embedded in the chimney mortar joints and folded down to cover the top of the step flashing

The corners are especially vulnerable. We usaully cut and bend the lead around the corner. Even with a good quality installation, this leaves one small spot that should be sealed with a high-quality Caulking such as Geocel.

The type of metal used for flashing depends on where you live. Aluminum and galvanized steel are sometimes used. Copper is the longest lived, but because its so expensive, we see it only on higher end jobs. Another advantage to copper is that the corners can be soldered for a watertight connection.

When a chimney is located at the bottom of a roof slope, a cricket should always be installed, a small diversion roof that prevents water from pooling and ponding behind chimney and eventually leading to seeping through roof into your house.

Because chimneys are such a potential trouble spot, inspect them once a year or two for loose or missing flashing and cracks in the masonry, or call on Robert Evans Jr. Contracting at 508-877-3500 and have one of our professionals do the inspection for you.  We also recommend that our customers waterproof their brick chimneys every few years with a brick sealer that can be applied with a garden sprayer. This is a great way to keep water from seeping into the brick.

Hi Dan,
Thanks for another job well done on the roof. I will continue to share my experience with Evans Contracting with my colleagues at our expanding MathWorks campus to hopefully drive more businesses for you. My father-in-law Leo would like to get a receipt from Evans Contracting for his record. Could you kindly send me one when you are free?

Tips for selecting a roof

Posted by Robert Evans on May 16, 2012 10:46:00 AM

TIPS FOR SELECTING A ROOF TYPE

1. Think BIG - View a full-sized shingle,not just a swatch or sample board.

2. Be Real - Look at actual house where the house and roof color combinations are similar to what you're considering.

3. Watch the light - As you look, notice how colors appear under changing light conditions and at various times of day.

4. Consider the pitch - Look for roofs with a similar pitch to your own. A roof's pitch affects the way you see its color.

5. Ask your contractor - They might be able to point you to a home where they've installed a roof of your style and color.
