If you’ve decided to have a new roof installed, there are some important things you should know before you begin the job. These steps include inspecting the existing roof, removing old shingles and metal flashing, and decking. You should also plan to remove existing insulation from the soffit vent openings.
Decking
Before you can start thinking about new roof installation, you need to inspect your current decking. If you notice any holes or sagging on the surface of the decking, it might be time to get it replaced. Check the decking and look for rot and black mold, which are both signs of heavy water damage. If you notice any of these signs, contact a roofing expert for advice.
There are several types of decking. One of the most popular decking materials is half-inch construction grade plywood. This material is typically installed with space between the boards to allow for thermal expansion and contraction. Another popular option is tongue-and-groove decking, which uses two-by-six wood boards that interlock when installed. This type of decking looks rustic and is popular for flat roofs without a ceiling. However, it may require additional vapor barrier and insulation between the decking and the outer layer of roofing.
Metal flashing
Metal flashing is a component of a roof system. It is designed to direct water away from the roof and into the drainage system. It is used in many places, including around chimneys, skylights, plumbing stack vents, bathroom vents, and other exposed areas of the roof. While it is often made of steel, metal flashing can also be made of aluminum.
Installing new flashing is an easy process. It is important to use the proper nails to secure each piece of metal flashing, and to seal the seams with caulk. The cost of metal flashing installation depends on the material and the amount of cutting needed. It should be noted, however, that it will take some time to complete the job.
Removing old shingles
Before installing a new roof, it is essential to remove the old shingles. This step can be difficult, but it saves you time and money. In the long run, it will make your roof look its best. Ensure that you follow the proper procedure to remove the old shingles so that you can begin the new roof installation without problems.
While you may be tempted to tear off the old shingles before you install your new roof, this may be a waste of money and effort. While it may seem like you’re saving money, the process of removing old shingles is more messy and time consuming. Moreover, the old shingles may also be a secondary layer of protection for your home. In addition to protecting your home from the elements, the additional layer can also help protect your home from storms.
Inspection
Before purchasing a new roof, you should have it inspected by a professional. The roof inspector will look for loose shingles and loose fasteners. These can indicate that your roof is nearing its end of life. He will also inspect the vent pipes, rubber boots, and seals around them. In addition, he will inspect the interior of the house for signs of water damage.
Roof inspectors will also check the soffit and fascia of your roof. They will also inspect your gutters and masonry chimneys for cracks or disintegrating grout. In addition, the inspector will look for proper venting in the attic. Poor venting can result in water leaks and other problems.
Time frame
There are many factors that affect the time frame for new roof installation. Some roof replacements are completed quickly, while others take more than three days. If you have a small home with a flat roof, most roofing projects can be completed in one day or two. However, if you have a complex roof structure, the time frame may be much longer.
The type of roof you choose will impact the time frame, as will the materials used to install it. If you decide to change the look of your roof, this may also affect the time frame.
