There are two basic types of roofing: flat and sloped. Flat roofing covers the entire roof surface, while sloped roofs have partial roofing. Both types require reroofing. When ripping off the old roofing, it is typically a better choice than a pitched roof. Roofing contractors have several ways to replace an old roof. Read on to find out what to look for and how to prepare your roof for reroofing.
One of the main factors in determining the correct roof for your property is the type and location of ventilation systems. Many homeowners are unaware of this, and they don’t consider this aspect of roofing until the last minute. During the pre-roofing conference, your roofing contractor should coordinate with your plumber. Incorrect placement of the vents should be addressed immediately, so that the installation process is as efficient as possible. This prevents any further damage caused by improper ventilation.
When selecting a roofing system, consider the cost. Low-cost systems are often less expensive, but they don’t come with all of the features that more expensive options have. Additionally, they may require more maintenance and energy. That means that they will cost more in the long run. Therefore, it is best to spend a little more money for a high-quality system. Alternatively, you can opt to work with a roof consultant or a roofing contractor to select the right system for your home.
A good example of this is reroofing. A reroofing job will involve less time and labor than a full roof replacement. It can even begin with the installation of the new roof, minimizing the amount of work on your home and the cost. When choosing a roofing contractor, ask them to provide a rough estimate of the total cost and time required for reroofing. The costs associated with reroofing will depend on the extent of damage.
Rooftop application equipment has increased dramatically since the 1980s. Larger ballast spreaders and ATVs are now used to apply roofing materials. These heavier equipments are more prone to damaging the building’s deck, so be sure to check the roof’s condition before deciding on a roofing system. Nevertheless, if the deck is strong, the heavy equipment shouldn’t cause too much damage. On the other hand, if the roof deck is not as strong, then it could be a disaster waiting to happen.
Another type of flat roofing is made of mineral wool. Mineral wool is a type of insulation that offers an R-4 rating (approximately) when used in low-slope roofs. It is also used as a replacement for fiberglass between rafters in residential construction. It requires a rigid upper layer, known as the cover board, and a flexible top layer (also called sheathing).
Flat roofing is also known as a ply sheet and is reinforced with an organic or glass-fiber mat. The bitumen used between the ply sheets is usually asphalt, tar, or a cold-applied adhesive. Asphalt or coal tar is heated before it can be spread evenly, so you need to be careful about the temperature of the bitumen. In addition to that, you can’t be certain that the membrane won’t shift due to wind and rain.
Before starting the roofing, it’s a good idea to hold a pre-roofing conference. This meeting should take place several weeks before the actual application of the roofing. During this time, it’s possible to identify potential problems and resolve them before the actual application. If you do not resolve these issues before the first conference, you can also schedule a second meeting to discuss any unresolved issues. The second meeting is a good opportunity to discuss any remaining concerns prior to the start of the application of the roofing system.
Another option for reroofing is called overlay roofing. With this method, the roofer installs a new roof over the old one. This way, you won’t have to remove the old roof. However, this option is only available once, and a roof can only have two layers. In this case, it’s worth considering an overlay over an existing roof. This option is typically more affordable, but it only works on a single layer of shingles.
