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.

Chimney Flashing

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.

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

Solar roofing panels

Posted by Robert Evans on Dec 3, 2012 6:22:00 PM

With the increased cost of energy today I see a lot of solar panels be installed on roofs. This is a great way to cut your energy cost, but I see a lot of these panels being installed over roofs that don’t have much life left in them. The solar companies should make the customer aware that there roof is in need of replacement, or at least tell the customer to get an estimate before proceeding with installation of solar panels. After solar panels are installed and a leak occurs in the roof and it is under the panels there is no way of fixing it without removing the panels
