The first step in roof installation is determining the size of the new roof. The roof’s surface area should be sized to account for the overlap of adjacent panels. Measure panels at ground level to ensure that the overlap is three to four inches. Then, fasten the panels to the substrate using self-tapping screws at two-foot vertical intervals.
Installing a second layer of shingles
If your roof is beginning to show signs of wear, you may want to consider installing a second layer of shingles. This will add an additional layer of protection for your roof, stopping leaks before they enter your home. It will also help direct water away from the home by directing it into your gutters and downspouts.
Installing a second layer of shingles can have many advantages, but it also has several disadvantages. The first is that it obscures the roof sheathing, making it harder to spot problems. If left unchecked, these problems can cause serious damage to your roof. In addition, a second layer of shingles adds additional weight to the roof decking, which can lead to damage in adverse weather.
Installing a drip edge
Installing a drip edge on a roof requires a skilled roofing professional. The best time to install this drip edge is before the roofing shingles are applied. If you are installing a new drip edge, make sure to follow local building codes. A professional roofing contractor should be factory-certified. Many prominent manufacturers have exclusive programs that recognize and acknowledge the best contractors.
The main purpose of installing a drip edge on a roof is to keep water from running behind the gutter and down the home’s fascia board. This moisture can cause the fascia board to rot. Because gutters are attached to the fascia board, rotted fascia board can affect the performance of gutters.
Preparing for a new roof installation
When your roof needs replacing, there are several steps you can take to prepare for it. The most important one is choosing the right contractor and developing a relationship with him or her. Ask for references and make sure the contractor has all the necessary certifications. It’s also a good idea to discuss expectations with the contractor. A good Orlando roofing contractor will provide you with a checklist of requirements, so you can ensure that you’ll be satisfied with the outcome.
You should move any heavy objects off of the walls and other areas of your house where roof construction will be taking place. The workers will need room to move their tools and materials. If possible, you can also park your car on the street during the construction. In addition, it’s a good idea to remove any hanging plants and cover flowerbeds with tarps.
Common pitfalls of DIY roof installation
DIY roof installation is often a fun, do-it-yourself project, but there are some important things to know before starting. Many DIY roofers make basic mistakes that can have long-lasting consequences. For instance, they don’t properly nail down the shingles or flashing, which will damage the shingles and your roof.
When it comes to roofing, DIYers should hire a professional contractor for safety reasons. A professional will know the proper tools and techniques for the job. A roofer will also know the correct way to install metal and make it blend seamlessly with the rest of the roof.
Cost of a new roof
The cost of new roof installation varies from home to home, and it depends on the size of the house and the material used. For a typical four-square-foot home, the cost can be anywhere from $4,700 to $10,460. However, the cost will rise considerably if the homeowner chooses to use more expensive materials. Basic asphalt shingles, for example, can cost anywhere from $4.50 to $6 per square foot, while other materials will cost more.
The cost of new roof installation is also affected by the geographical location of the house. Certain parts of the country experience higher costs than others, such as the Pacific Northwest, which experiences constant rain. For this reason, homeowners should get multiple estimates.
