Traditionally, the purpose of the code requirements for roof systems was life safety. However, these days, the emphasis is on general serviceability. Many code requirements are now geared toward other concerns, including airtightness. One example of this is the addition of provisions for reroofing projects. Here’s how these changes affect the roofing industry. Listed below are some of the most important provisions for roofing systems. But are they really necessary?.
If you have two or more layers of shingles, reroofing may not be the best choice. Besides, it will make the entire roof too heavy. Moreover, it won’t fix extensive damage that isn’t covered by extra layers. Therefore, reroofing is a great option for homes that don’t need a complete roof replacement. This method reduces the overall time and expense of the project.
Unlike shingle roofing, which requires tearing off the old roof, reroofing is not permanent. The roofer will install a new one over the old one. However, this method only works once. Since the roof can only be two layers thick, reroofing can be costly. As a result, you should consider the pros and cons of each method. If you’re unsure, consider hiring an expert.
The most common type of roofing for flat roofs is asphalt roll-roofing. This material comes in three-foot rolls, with protective granules on top. The rubber membrane acts like a large inner tube and is held down with mechanical fasteners. In some cases, rock garden ballast is also used as a barrier. So, choose a type of roof that will best protect your home. You’ll be glad you did!
The best way to avoid a misunderstanding on a roof project is to hold pre-roofing conferences with the contractor. These should be held at least several weeks before the actual application. During these meetings, you can identify any problems before the work begins. During these conferences, the roofing contractor will also have representatives from roof covering material manufacturers, mechanical and electrical contractors, lightning protection systems contractors, and a third-party inspection firm. These conferences can help you identify any concerns and improve the overall project.
Successful roofing projects require two distinct phases. A design team must identify all criteria early in the process to integrate project requirements and system selection criteria. Once the project requirements have been integrated, the specifics of the roofing system are developed and designed. These specifications specify the specific characteristics of the roof system, such as deck type, insulation type, fastener patterns, warranty requirements, and design concepts. A roof contractor will use these specifications to build the roof. Once the design team is satisfied with the design and selection, the roofing contractor can start work.
A life-cycle cost assessment of a roofing project involves the initial construction cost, energy consumption, maintenance costs, and repairs, as well as the lifetime of the roof. Life-cycle cost analysis also considers the cost of re-roofing and disposal at the end of the roof’s service life. The longest lifecycle cost assessment is the design service life, which is most difficult to determine. The average service life for a new roof is around 20 years.
A designer must also prepare appropriate drawings and specifications for a roof. Properly prepared documents prevent premature roof failure. A roof designer should have sufficient knowledge of materials and roofing systems. If the project involves large construction, a roof designer should be involved, as this individual should be derived from the design. The manufacturer of the roofing system should also state that they do not design a roof. If you have no experience in the field, the designer can provide you with a roofing design manual.
When selecting a roofing system, it is important to consider its warranty. While many roofing systems come with a manufacturer’s warranty, this shouldn’t be the sole consideration. A good warranty will cover the entire roofing system, including all the materials and accessories. Also, the warranty should be broad, covering basic wind speeds and materials. Make sure the warranty covers materials and accessories, and has no dollar limit or pro-rating. And don’t forget to choose a warranty that is backed by a company with excellent customer service and support.
