This is what is normally done. Cut the shingle at the notches to make 3 ridge shingles.
No, cut a whole shingle in thirds at the cut outs.
2/3 of a bundle of shingles which has approx. 22-23 shingles
Shingles vary in dimensions, and sometimes there are specific bundles of shingles made for the sole purpose of ridge coverage. If you are using the house shingles for ridge, take the length of ridge to be covered, divided by the exposure of the shingle to determine the number of ridge pieces needed. Normally you will get three pieces out of one full shingle. Once you determine the number of full shingles, find out how many shingles are in a bundle and purchase the smallest bundle of shingles necessary to complete the job.
certainly, cut them 12" wide
Cut three tab shingles for your ridge cap. (20 year)
Not all pallets of shingles have the same number of bundles. It depends on the size and weight of the shingles, as well as the manufacturer. Timbertex Ridge Cap shingles come 30 pieces to a bundle and 33 bundles on a pallet.
15 lb felt, 1 1/2'' plastic caps , 20" valley metal, 1 1/4" nails, Ridge vent, 2 1/2" ridge nails, feild shingles, 3 tab shingles (for starters and ridge), air hawks & white drip edge.
Chlorine Bleach. Simply pour over the moss, wait a day or two and it will come right up without damaging the shingles. You can even sweep it off with a broom. Since the bleach won't react with the asphalt in your shingles, it is perfectly safe to use. I have used a product called moss off. It comes in a sprinke can & you sprinkle it around the ridge of the roof. Then next rain activates it and the runs down to cover the roof. Works pretty good & its not too expensive
4 bundles of shingles covers 100sq.ft. of course this is approx. shingles come in several sizes and then you must allow for waste cuts etc
Yes you can. You will want to cut back any shingles that over hang the edges. Then put 1x4 slats on 19.2" centers parallel to the ridge of the roof make sure to hit the rafters when you nail down the slats. Do not use treated slats as they will react to the metal. Then screw down the metal the the slats.
If you have cut up roof you will need just under 10% for starters and ridge cap. (3 tab) Example a 60 square roof would need 5-6 squares. Lower pitched roofs would of course require less.
One square covers 100 square feet, so to cover 1900 square feet of roof you would need 19 squares. However, you also need "starter shingles" and "hip and ridge" shingles, plus you need to have a few extras because of waste from cutting angles. Starter shingles go around the perimeter of the roof as a bottom layer for the first course of shingles. Hip and ridge shingles go, as you might expect, on the hips and ridges. In order to know for sure the exact quantity you would need for the entire roofing job you have to measure all of these areas.
