A well-planned roof installation requires the proper amount of preparation. The tiles should be laid with the correct head-lap and exposure. The tiles should also be evenly spaced and have a minimum depth of 3 inches. The underlayment should be nailed with corrosion-resistant nails of at least 11 gauge. These nails should be at least 5/16 inch in diameter, and at least 48 inches long. They should be nailed every 48 inches and laid out in rows with equal courses. Using a pneumatic nailer can help drive nails with ease.
The underlayment is another important component of a roof. It not only catches water but protects the framing and sheathing underneath. The underlayment is placed beneath the drip edge, which may require pulling up the drip edge. A metal drip edge is then installed over the ice and water shield. Usually, the roofer fastens down the underlayment with cap nails every four to six inches along its edge.
During the roof installation process, the roofing sheets should be lined up in order to prevent shifting. This will affect the protection provided by the roof in the long run. In addition, when applying the adhesive, ensure that it is applied to the underside of the membrane, so that no exposed nail heads show. After that, the plumbing vents should be secured with a moldable aluminum jack, which should be bent to fit the profile of the roofing.
A good roofing contractor should also carry necessary insurance for its employees. This insurance covers workers who might get injured during the installation process. Moreover, it is crucial to check the reputation of the company in the market. The internet is a great source for independent third-party reviews. If possible, purchase at least 10% more material than what you think you’ll need. This will help you cover any unforeseen problems such as odd cuts and mistakes.
Another important factor in planning for roof installation is the season. During the spring and early summer, temperatures are relatively mild and the contractors have more time. However, the middle and end of summer are too hot and humid. During these seasons, the demand for roof installation is high and contractors often raise their prices. However, it is best to schedule your roof installation during the late spring or early summer. Nevertheless, it is important to consider the weather conditions in your area since these seasons have different climates.
For a residential application of metal roofing, 24 or 26 gauge panels are most commonly used. Many manufacturers also provide factory-made panels, which eliminate the need for special equipment on site. These panels are also longer and eliminate the end-lap joints. The panels can also be fastened together with clips placed 20 to 24 inches on center.
Measurement of roof area can be done easily. You should measure the area of the roof using a long level. Make sure you mark a foot on the level. Once you have the measurement, you should add an inch. This means that the slope of the roof is 3/12. This means that the roof is 3 inches high for every 12 inches of run. Using this information, you can calculate the area of the roof.
Another thing to consider is the quality of the underlayment. Many manufacturers have proprietary underlayments that are more durable and less slippery. They also provide better fire ratings. It is important to check if the shingle manufacturer offers fire-resistant underlayments. If the manufacturer doesn’t offer them, you may want to consider using another company.
Lastly, consider the price. Some roofs are cheaper than others. A metal roof is an excellent choice if you need a durable roof. Though metal roofing requires specialized contractors, it can last for 80 years or more with proper care. It’s also important to make sure you hire a top-rated roofing contractor. This way, you can rest easy knowing your home is in good hands.
