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 )

What are starter shingles ?

Posted by Dan MacDonald on Apr 22, 2019 2:03:42 PM

After the appropiate ice and water barrier and underlayments are properly installed, installation of the roofing shingles begins with starter shingles on the eaves to protect the leading edge of the roof.

Visually , homeowners enjoy the design benefits a cohesive roof system provides. As a example, matching starter shingles allow the first course of shingles to blend in seamlessly with the rest of the roof. The same is true with ridge/cap shingles designed to match in color and shape, accenting the enhanced profiles and textures of laminate architectural or designer shingles.

Starter shingles are designed to increase protection against water intrusion and blow-offs. Installation of starter shingles is fairly straightforward for seasoned contractors. For three-tab and laminate/architectural shingles, cut 6" inches off one end of the first starter shingle. Apply the starter shingle on a lower corner of roof , overhanging the rake and eaves edges, including perimeter metal drip edge, by 1/4 to 3/4 of an inch. Making sure the starter is positioned with the factory-applied sealant strip face up and the strip adjacent to the eave edge of the roof. That then gets fastened with 4-6 nails 11/2 to 3 inches up from the eave, not in the seal down strip , with one fastener 1 inch from each side of the starter. The remaining nails should be evenly spaced on the same line as the end fasteners. Continuing the coures across the eave with full length starter shingles and butt them loosely together to avoid buckling.

After completing the underlayment, drip edge and starter shingles and all are in place , the roof is adequately prepared to start installing shingles. In addition to the cosmetics, using a single-source manufacturer allows roofing contractors to learn the precautions or limitations that could affect product compatibility and help avoid potential problems.

Tips For Your Home's Roof This Fall

Posted by Dan MacDonald on Sep 10, 2018 3:22:14 PM

Its that time of year when the weather starts to turn and get alittle cooler, the leaves start to change, and you know that its not too long before winter weather is on the way. It's also a time of year when you should be doing some home maintenance to avoid any possible damage the harsh winter months can bring to your home.

  1. Have a Roof Inspection

Many homeowners think that if they don't see any obvious problems on there roof that they don't need to get it inspected. The Problem is alot of times that roof leaks can go undetected for years. Only a experience roofer can identify any subtle issues that can turn out to be a winter disaster

2. Make Roof Repairs

If you or your roofing contractor do find any issues like- damaged, missing, or broken shingles or even pipes that penetrate the roof can get damage around the seal of the flanges. Its important to get these issues repaired or replaced immediately. If you wait to long the Snowy New England weather will arrive and you'll have to wait for a rare warm stretch during the long winter months or having to wait until spring time to address the issue. Meanwhile, the snow, water, ice, and wind are probably doing more damage to your roof that could have been avoided had you decided to fix it sooner.

3. Clean Gutters and Trim back trees

With the season changing to fall the leaves change colors before falling off the trees. Falling leaves dont just fall in your yard, they fall on your roof and make there way into your gutters and downspouts. If you don't spend the time to have your gutters cleaned, those leaves will create a problem as more precipitation falls and water can't make it into the drain spouts. Colder Temperatures with debris-filled gutters will put your home at a higher risk of Ice Dams that can damage your roof and the inside of your home.
