Method Of Installing Asphalt Shingles
Asphalt roofs are the most common type of roof in North America. These have some benefits and several drawbacks. Asphalt roofs are good because they go easy on the pocket and are convenient to set up need negligible maintenance.
Asphalt shingles are made with organic felt or fiberglass saturated with asphalt and encrusted with ceramic or stone granules. This encrusting gives asphalt roofs a hard surface, colour and the ability to reflect some sunlight.
Each asphalt shingle is 36 inches long and 12 inches wide and has two tabs that divide it into three equal parts. For making the shingle stick to the roof, there is soft tar beneath these tabs. Shingles are sold as squares that each cover 100 square feet.
A roof shovel / a square-ended spade, roofing nails, a hammer, new shingles, a ladder, some rope, and a chalk line and safety gear such as gloves, kneepads and shoes with good grip are some of the things you will need to install new asphalt shingles.
First of all, you have to remove old shingles. Employ the square-ended spade to remove nails by pushing it under the shingles to loosen the nails. Inspect the waterproofing membrane, the roofing felt and the roof deck for damage. Rotted panels of the deck have to be replaced and nailed down properly.
Replacement of damaged roofing felt and waterproofing membrane also has to be done. But prior to shopping for them and also for shingles, it is wise to measure the roof and buy 10% extra material so that wastage is accounted for.
Begin installing the shingles such that the first one is laid at the bottom left corner when you are facing the roof. The edge of the roof has to be covered with the starter course, which is just half shingles. Three tab full shingles are used for the rest of the roof. All shingles must overlap the neighboring one by half an inch.
When required, the shingles can be trimmed for better setup. Working from the bottom to top and then moving sideways is a convenient way of installing the shingles. Shingles that meet at the ridge of the roof from all the sides should be overlapped and secured with nails.
