Roofing a house is usually a job best left to professionals. Pros often are accustomed to working on sloping high surfaces, can purchase materials cheaply, and have specialized tools to make the job go faster. When dealing with a roofer, it is good to know how much area needs to be covered, and this calculator will enable you to do that.
A few tips: To figure the size of your roof, see our square footage calculator. In roofing terminology, a "square" is 100 square feet. Composition shingles (asphalt or fiberglass) come in bundles that cover 1/3 square. Roofing comes in rolls 3 feet wide and 36 feet long, for a coverage of about 1 square.
When installing roofing over bare wood, roofing felt -- often called tar paper -- is laid down first. A roll of 15-pound felt covers about 4 squares; a roll of thicker 30-pound felt covers 2 squares. When ordering any of these materials, add 15 percent for waste.
Exterior Project: Building Steps
Now, we wanna concentrate on building the steps that will take you from this level down to this level. Greg is gonna help us out today. Now, I tell you building steps used to be a very intimidating thing, but now, with the precut step stringers like this, it's made a lot easier. With again by measuring the width of the opening and cutting the tread to 2 x 4 to serves as an anchor for the steps. We drill through it and into the bricks so that we can attach it with masonry screws. On each end, we now wanted the stringers. We cut an inch and a half of the top of the remaining 3 stringers and toenail them into the 2 x 4 at 16-inch intervals, a 1 x 8 nail across the front. Hold it altogether so that we can again put on the treads, in this case, 5/4 x 6-inch deck boards butted up against each other and overhanging the ends slightly. The risers are cut from the 1 x 8 stock to cover the remaining vertical openings, and our stairs are done. Oh, our steps just turned out perfect and I'm glad that we made them as wide as we did the full width of the double doors, and instead of just 3 footsteps, I can see so many times. This looks better plus a little bit of extra CD, and might be a perfect place for a few pot of plants after the patio is all complete.
