Asphalt Shingling, Built-Up Roofing and Wood Shingling

Asphalt shingles are the most common type of roofing material used on pitched roofs. They are lightweight, comparatively inexpensive, and available in many different colors, sizes, and shapes. Asphalt shingles are sold in the form of individual shingles or as strips of shingles joined together in two, three, or four tab units. The strips are 36-inches long. Their width will vary from slightly over 11 inches to 12 inches wide, depending upon the style and manufacturer. Lock-type asphalt shingles are also available in a number of different styles. Before laying a new roof with asphalt shingles, you must first calculate the total area to be covered. A high school plane geometry text will provide you with the formulas necessary to calculate the square footage of surface area. Many roofs form uncomplicated rectangular or squares. Unfortunately, hip roofs, dormer roofs, and other types of minor roofs present more complicated surfaces. In any event, the total square foot area of the roof covering the structure must be calculated. Continue reading Asphalt Shingling, Built-Up Roofing and Wood Shingling

Tile Roofing, Slate Roofing and Metal Roofing

Roofing tiles are made from a variety of different materials, including shale, shale and clay, cement, cement and asbestos, and metal. Both curved and flat types are available for installation on roofs. Curved tiles are manufactured in the mission and Spanish style designs; flat tiles in the shingle and interlocking designs. Mission roofing tiles are laid in courses which overlap on alternating sides. The concave side, or cover, forms a course Cover Tile Used to Cap the Ridge of tiles which overlaps with the convex parallel courses on either side. The cover tile is nailed to a wood strip fastened to the roof sheathing; whereas the pan tile is nailed directly to the sheathing. The roof ridge is capped by a cover tile which is nailed to a wood strip fastened to the ridge. Continue reading Tile Roofing, Slate Roofing and Metal Roofing

Roof Accessories: Gutters, Downspouts, Drip Edge, Ice Shield

Nowadays, no modern roof can’t do without appropriate accessories. This is not a whim of customers, but a trend confirmed by professionals, which ensures the reliability and durability of the roof. Roofing accessories are used not only for roof decoration purposes but also for the creation of a single reliable construction, resistant to the impact of snow, wind and storm loads. Roofing is an integrated engineering system, the long-term operation of which directly depends on the compliance with technological processes of installation and further maintenance. To a certain extent, roofing accessories also contribute to these tasks. Roof accessories include drip edges, gutters, ice shields and so on.

Plumbing Roof Vents

Unless your backyard has a tall, narrow building with a crescent moon cut in the top of the door, there are plumbing vents on the roof of your home. Each sink drain, tub, or shower in the home has a vertical U-trap that stays full of water. The water in the traps and the water in the toilet keep methane and other gases of decomposition in the sewer system from traveling back into your home. However, these gases have to go somewhere, so the home has vertical vent pipes that carry these gases through the roof to the open air. Vent pipes expand and contract as the temperature changes, so these pipes need to fit loosely through the sheathing and shingles. The pipe also needs to have room to play inside the neoprene collar or all lead flashing, depending on which one you use. Continue reading Plumbing Roof Vents

Metal Chimneys, Pot Vents, and Power Ventilators

Metal chimneys, pot vents, and power ventilators are large roof penetrations. All of them have a vertical component that rises above the roof and a base woven into the shingles. The lower edge of all the base plates comes down over the tops of the exposed tabs of the lower course of shingles. Instead of a simple notch, you cut several courses of shingles to fit along the sides of the vertical component. The bottoms of the tabs of the shingles laid around and over the vertical component are cut in a rounded curve to fit the outline of the top of the vertical component. Lay these courses back toward the obstruction from the new base and offset lines you reestablished beyond the obstruction. Cut the shingles to shape so they fit along the side of the obstruction.

Step Flashing on a Roof

Step Flashing is metal laid with the shingles to seal along a straight vertical obstruction such as a wall, brick chimney, or skylight. All step flashing is laid basically the same way. You can buy step flashing in mill finish (unpainted) aluminum, enameled aluminum (black, brown, and white), copper, or galvanized metal (but don’t use the galvanized). Modem step flashing is manufactured from 5″ x 7″ rectangles. The rectangles are bent 90° so that a 2-inch leg goes up the wall and the 3-inch leg goes over the top of each shingle as you lay it. Always lay each piece of step flashing on each succeeding course at the same location on the shingle. Each piece of step flashing, or step is 7 inches long. The courses of shingle are only 5 inches. When you nail each succeeding piece of step at the same location on each succeeding shingle, the upper piece of step overlaps the lower piece by 2 inches. I always set my piece of step with the bottom of the step just above the self-sealing strip. Keeping the strip exposed lets the shingle seal all the way across to the vertical leg of the step.
