Roofing Valleys Correctly

Posted by Robert Evans on Feb 20, 2019 10:59:42 AM

Welcome to Robert Evans Jr. Contracting

Weaved Valley

Depending on your roof design you may or may not have valleys. A Valley is where 2 roof lines come together. Here is a picture of Robert Evans JR. Contracting Inc. installing a Weaved "Closed valley".  Closed valleys are those where shingles on one or both sides of the roof extend across the valley onto the adjacent roof slope. There is two kinds of closed valleys: cut valleys, which are less expensive to install {due to less waste in material and quicker labor install} and are the most common, and there are woven valleys as you see above in this picture. When Installing the woven method, shingles from both roof slopes run through onto the adjacent slope, alternating with each course. This is done differently with different types of roofing shingles depending on 3-tab, thickness, archtectural type shingles. Woven valleys is not recommended to be installed on a roof pitch less than 4:12.

Recycling Roof Shingles

Posted by Dan MacDonald on Jan 4, 2019 12:24:08 PM

Roof Shingle Recycling

The EPA estimates 11 million tons of asphalt shingle wast are generated in the U.S. each year. About 10 million tons comes from roof installations and tear-offs and the remaining 1 million tons are scraps from the asphalt shingle manufactures. Every ton of shingles that is recycled instead of sent to landfills is equivalent to saving one barrel of oil form use, according to the Northeast Recycling Council. Clearly, diverting asphalt shingles away from landfills can have a significant and positive environmental impact.

Most recycled asphalt shingles are ultimately reused in road construction or maintenance. State-level Department of Transportation (DOT) offices have the authority to specify whether recycled asphalt shingles can be used in state-funded road projects, and many DOT offices have granted permission. Use of recycled asphalt shingles in road construction is said to increase asphalt stiffness and decrease cracking and rutting, resulting in longer-lasting roads. According to the National Asphalt Pavement Association, nearly 950,000 tons of recycled asphalt shingles were used in asphalt pavement mixtures during 2017, which was a 32.1 percent decrease from the previous year. The decrease highlights the need for more asphalt shingle recycling facilities. Sometimes it can be hard for contractors to find a company that recycles asphalt shingles especially in rural areas.

Here At Robert Evans Jr. Contracting Inc. we recycle all of our ashpalt shingles tear-offs and scraps at Conigliaro Industry in Framingham Mass. to help stay environmentally friendly.

How To Prevent Ice Dams From Forming on Your Roof

Posted by Dan MacDonald on Nov 16, 2018 10:45:29 AM

If you have icicles along your eaves/overhangs, or ice collecting on your roof , Proper attic insulation may be the Key to help keep that frozen precipitation from building up .

Heavy snowfall can be a nice sight as it happens but there are a number of problems that can result from these storms. What do you do when you notice water pouring down the inside of your walls and the ice starts ripping off your gutters ? The key is to find a cure to the problem before it gets to this point .

Icicles form along the eaves/overhangs on your house as a result of a warm attic to heat loss through your poorly insulated ceiling . This causes the heat from the inside the house to melt the snow on the roof before the sun can melt the snow and it collects at the eaves, which are colder because there is no heat above the overhang.

Can icicles damage my house?

The result of icicles that develop along your eaves/overhangs is potential leaks inside your walls when the ice also builds up on the roof. This Buildup of ice and snow is called an Ice Dam.

The cure for this is a two-step. The heat loss can be stopped with proper insulation, usually standards are 13 inches of blown-in cellulose fiber insulation R49 is recommended.

The Other half of this cure is proper ventilation at eaves and at the ridge of the house. This is done by adding soffit vents and a quality ridge vent.

Your Insulation specialist should be able to recommend you on the number and lengths of vents needed . The typically recommended is 1 square foot of vent for every 150 sq. feet of attic space .

If you have ice dams that end up forming on your roof , best advise is to Hire a professional contractor to clear the ice , or you can risk doing considerable damage to your roof or even worse ,seriously injuring yourself .

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.

Roof Maintenance

Posted by Robert Evans on Jun 18, 2014 3:17:00 PM

Customer whose roof we installed in 1997 called and said he had a couple of small leaks.

Upon inspection of we discovered trees over grown on the roof and some of the limbs had penetrated the rubber, thus causing some leaks. The gutters were completely filled and the neighborhood kids had been throwing all sorts of debris on the roof.

I called the customer back after inspection and told him what I had discovered. Since his warranty had run out and the roof had been neglected that there would be a fee to repair, we give him another option. Which was for a fee we would go over the entire roof and perform all repairs and preventive maintenance and give him a three year warranty.photo1MA30986752 0001 resized 600photo3MA30986752 0003 resized 600photo4MA30986752 0004 resized 600photo5MA30986752 0005 resized 600

Ice Dams

Posted by Robert Evans on Jun 2, 2014 6:53:00 PM

It might seem a little bit strange to be talking about ice dams in June , but now is the time to deal with them. One customer in Natick was having ice damming issues on his Campanelli ranch which are very prone to ice dams. This particular house had a addition on the back with a low pitched roof on the north side of the house. This combination is what it takes for an ice dam. Instead of waiting until the last minute he decided to get it done now.The resolution was strip off the shingles and install a rubber roof. No more shoveling his roof this winter.photoMA30984285 0001 resized 600photo1MA30984286 0002 resized 600photo2MA30984286 0003 resized 600

Roof Framingham

Posted by Robert Evans on Apr 5, 2014 3:54:00 PM

Boyle Bros. funeral home in Framingham discovered a leak this winter and called us to look at it, on the flat section of there building a rubber was installed over a tar and gravel roof. A half inch fiber board was mechanically fastened over the tar and gravel, the problem with fiber board in a go over application is it acts like a sponge and sucks up water before showing any signs of a leak.

In Boyle Bros. case the roof had been leaking for years from a hole in the rubber and until the weight of this winters snow squeezed the water from the saturated fiber board.

We stripped off the roof and installed a new rubber roof with half inch recovery board instead of fiber board. With a warranty of ten years on our labor and fifteen years on materials we included an inspect of the roof in the fallphoto1MA30970304 0003 resized 600photo3MA30970304 0005 resized 600photo4MA30970304 0006 resized 600

Vinyl siding

Posted by Robert Evans on Feb 3, 2014 1:17:00 PM

-Request a Qoute!

Vinyl siding is plastic exterior siding for a house, used for decoration and weatherproofing, imitating wood clapboard, and used instead of other materials such as aluminum or fiber cement siding. It is an engineered product, manufactured primarily from polyvinyl chloride (PVC) resin.

Approximately 80 percent of its weight is PVC resin, with the remaining 20 percent being ingredients that impart color, opacity, gloss, impact resistance, flexibility, and durability. It is the most commonly installed exterior cladding for residential construction in the United States and Canada.

 

 

History

Vinyl siding was introduced to the exterior market in the late 1950s as a replacement for aluminum siding. It was first produced by an independently-owned manufacturing plant called Crane Plastics in Columbus, Ohio. The process was originally done through mono-extrusion. At that time, blending of colors was done manually.

This original process made it difficult to produce and install a consistent, quality product. Beginning in the 1970s, the industry changed its formulation changes to improve the product's production speed, impact resistance, and range of colors.

In the following decade, vinyl siding grew steadily in popularity in large part due to its durability, versatility, and ease of maintenance. However, in many European countries, for instance Germany, vinyl (PVC) is rarely used or phased out because of its negative environmental profile.

Modern manufacture

Today, vinyl siding is manufactured by coextrusion. Two layers of PVC are laid down in a continuous extrusion process; the top layer is weatherable capstock, which comprises about a third of the siding thickness. This capstock includes about 10% titanium dioxide, which is a pigment and provides resistance to breakdown from UV light. Vinyl siding, like paint, will inevitably fade over time, but the fade rate is somewhat slower with vinyl, and in any house cladding (vinyl, paint or others) the intensity of the color is in direct correlation to the rate of fade. For example, two currently popular colors are "barn red" and "clay". In reaction to sunlight, the barn red will fade faster than the very neutral clay color whether paint, vinyl siding or other composition. The lower layer, known as substrate, is typically about 15% ground limestone (which is largely calcium carbonate). The limestone reduces cost, and also balances the titanium dioxide, keeping both extrusion streams equally fluid during manufacturing. A small quantity of tin mercaptan or butadiene is added as a stabilizer to chemically tie up any hydrochloric acid that is released into the PVC material as the siding ages. Lubricants are also added to aid in the manufacturing process.

Specs and product variables

Vinyl siding can be observed in a wide range of product quality realized in a substantial difference in thickness and lasting durability. Thickness can vary from .035" in cheaper grade siding products up to .052" in the highest grade products which vary from manufacturer to manufacturer. Today, the thinnest vinyl siding commonly used is .040", and is known as "builder's grade". Vinyl product can vary in thickness even within one manufacturer up to .010" of thickness through varying product lines offered that range from basic to premium-grade products. Thicker vinyl products, usually realized in higher cost, are more rigid which can add to the aesthetic appeal and look of the installed, inherently flexible product and also add to durability and life expectancy. Thicker grades of vinyl siding may, according to some, exhibit more resistance to the most common complaint about vinyl siding – its tendency to crack in very cold weather when it is struck or bumped by a hard object while others feel that a thinner product may allow more 'flex before cracking' and is a subject of debate. However, at "This Old House" website, this assertion about thickness and crack resistance is disputed. They claim to know of test results that indicate chemical makeup has a greater influence on impact resistance than does thickness.

Chemical formulas can also vary somewhat from manufacturer to manufacturer which can impact life expectancy as formulas and possibly manufacture process can be one of the most important in terms of product quality and durability. One important advent was a UV coating,  utilized by some manufacturers that was applied to the surface of the product that filters out UV spectral light from the sun which would otherwise degrade the PVC more quickly. As a rough general rule, the higher the grade (and price) of the siding, the more resistant it is to fading (intensity of the color being taken into consideration, as mentioned above).

Vinyl siding is manufactured with its own partial fastening or locking system that is coupled with nails that 'loose' fasten the product to the exterior wall. This locking system can be either a rolled or an extruded lock depending on the manufacturing process, either of which has its own design considerations. This locking system, either extruded or rolled has a bottom lock which locks into either a start piece or onto the top lock of the panel below. The top lock is then 'loose' nailed to hold the panel to the wall. This 'loose' nailing allows for float which is created by expansion and contraction from varying temperature and weather conditions. With well designed siding, and proper 'loose nailing' installation, the siding can easily expand up, down, in and out, and left and right without restriction. Vinyl siding, by its nature, will tend to expand and contract more with temperature extremes than any other common type of cladding.

Environmental aspects

From an environmental standpoint, vinyl (PVC) siding has been called a "disaster". The production of PVC and its feedstocks, vinyl chloride monomer and ethylene dichloride results in the release of hundreds of thousands of pounds of toxic chemicals into the environment each year, mainly in poor, communities of color in Louisiana and Texas. PVC production is also a large source of dioxin into the environment.

Vinyl siding, like natural wood siding, is flammable. The natural fire retardancy of PVC is a double-edged sword in that building materials may smolder for long periods of time giving off hydrogen chloride gas long before visible signs of fire appear. Because of its majority chlorine content, when PVC burns in fires two extremely hazardous substances, hydrogen chloride gas and dioxin are formed which present both acute and chronic health hazards to building occupants, fire fighters and surrounding communities. In addition, when PVC burns, some 100 different toxic compounds are produced. Because of its thin profile, vinyl siding may be more likely to ignite due to exterior fire; for example, the National Institute of Standards and Technology found that, in tests involving vinyl-clad structures in close proximity, fire was observed to spread between two vinyl-clad test structures located six feet apart in fewer than five minutes.Additionally, vinyl siding can release toxic fumes when burning, particularly dioxins. This is not only an environmental concern, but the fumes can be dangerous to firefighters and bystanders, and the toxic fumes released may increase the likelihood of fatality from smoke inhalation for anyone trapped in the burning structure.

The National Association of Home Builders (NAHB) recommends using building materials that require "no additional finish resources to complete application on site" for green home builders as they reduce waste and materials used. Installing vinyl siding involves neither paint, stain, nor caulk and thus meets this NAHB requirement.

Environmental Building News wrote in its January, 1998 issue that "while Greenpeace has been most vocal regarding environmental and health concerns with PVC (vinyl), they are by no means the only voice out there expressing such concerns. There is widespread concern within the environmental and toxicology communities, not only about PVC and the products associated with its manufacture and disposal, but also about chemicals that are added to PVC to give it specific properties for building product applications. The plasticizer DEHP, for example, has been the focus of recent concern. "we stand by our concerns about PVC-based building products for both environmental and health reasons."—ebn, January 1998, page 3.] The position of the International Association of Firefighters, which represents fire fighters in the U.S. and Canada is: "Due to its intrinsic hazards, we support efforts to identify and use alternative building materials that do not pose as much risk as PVC to fire fighters, building occupants or communities."

The PVC used in vinyl siding used to be produced in open vats until 1971, when angiosarcoma, a rare cancer of the liver, was traced to vinyl chloride exposure among PVC workers, and strict workplace exposure limits were established by the Occupational Safety and Health Administration. These changes required all vats to be tightly sealed, which led to greater capital costs and a concentration in the number of producers.
