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.

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 .

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.

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

Flat roofs

Posted by Robert Evans on Mar 5, 2014 9:02:00 PM

This winter has been very hard on flat roofs with the snow loads and persistent cold. Flat roofs are not maintenance free if the roof is eight years or old it might be time for an inspection, especially if you had leaks. Just because you had a leak doesn't mean the roof needs to be replaced, however waiting is the worst thing you can do. Depending on what type of insulation is used and if it is just one layer or two it could leak for months before showing signs of leakage. Many times the life of a flat roof can be extended with repairing of seams and penetrations. For a cost the faction of a roof replacement striping out seams and penetrations will add years to the life of a roof. In many cases we have offered warrantys to the building owners after doing such maintenance.

Roof Leaks

Posted by Robert Evans on Nov 27, 2013 10:00:00 AM

describe the imageSome times when a roofer contractor does a new construction roof they don't install counter flashing and just use the lead on the chimney and this is what you get in a wind driven rain.
