Weathertightness担保值得这笔钱吗？

A Weathertightness Warranty (WTW) is intended to be an assurance from a metal roofing manufacturer that a newly installed standing seam roof will not leak for a specified period of time. They are most often used on municipal and commercial projects where a specification has been created by either an architect or design building professional. While WTW’s can certainly offer protection, they can also cause a great deal of confusion and add cost to the overall project budget.

At first blush many folks think all Weathertightness Warranties (WTW) work the same; however, nothing could be further from the truth. Instead, there are actually many different types of Weather Tight Warranties.

如果您正在考虑在项目上指定Weathertightness保修，那么重要的是要了解一些基本术语，以确保您和您的所有者都获得预期的保护。

Weathertightness保修有五个主要组成部分：

1. Warrantied Systems
2. Involved Parties
3. Warranty Length
4. 保修责任限制
5. Optional Coverages

Warrantied Products

Weathertightness保证are available for only selected panel styles. As a rule of thumb you can expect to see exposed fastener systems excluded from WTW offerings. Instead, they are more commonly available for concealed fastener style standing seam panels that are installed to predetermined minimum roof slopes. While most reputable manufacturers (McElroy included) offerstandard availability guidelineson their websites, it’s always best to reach out and discuss your project specifics to ensure that a warranty will be offered.

Involved Parties

Joint Warranty:As the name implies, these warranties split liability between the panel installer and the panel manufacturer. In these types of warranties, the contractor is typically responsible for the first two years of leak-free service. Once two consecutive years of leak-free service have been achieved, then the manufacturer is responsible for the remaining warranty term. It is important to note that the manufacturer's warranty doesn’t begin until two years of leak-free service have been achieved under the contractor portion.

Pros:

• Most economical WTW

缺点：

• No manufacturer protection exists until two years consecutive leak free service has been achieved by the contractor. As long as the installing contractor remains in business and services the warranty, this becomes a moot point.

Single Source Warranty:与刚刚讨论的联合保修不同，单一来源保修从第一天开始对制造商的全部责任承担了项目的天气紧张。

Pros:

• Manufacturer responsibility from day one can lead to greater peace of mind.
• 制造商参与承包商选择，培训和批准工作细节的更多参与可以净化（但不能保证）质量更好的安装。

缺点：

• 更高的保修费用
• Manufacturers may limit this warranty to specific contractors with proven experience, training etc. When this occurs, it can frustrate contractors that want to bid the project but are unable to gain manufacturer support.

Warranty Length

As you would expect, warranty length refers to the length of the warranty coverage. Most reputable manufacturers offer lengths ranging from 5-25 years although 20 years is the most common warranty length. Warranty length and cost are directly related. As the warranty length increases, the cost of the warranty also increases.

保修责任限制

The third element of a Weathertightness Warranty (WTW) is the dollar amount of protection provided. Most reputable manufacturers offer various limits ranging from as little as .08 sq ft on the low end to what is often referred to as no dollar limit or no repair limit on the high end with many levels in between. As the coverage provided by the warranty increases, so too does the cost of the warranty.

关于保修限制的谨慎性：当规格要求“制造商的标准Weathertightness保修”时，某些制造商竞标最低覆盖范围并不少见。尽管您可以想象，这种做法可以帮助他们以低价赢得该项目，但事实之后，这通常会导致沮丧。与其使用术语“标准”，而是在编写规范和wtw时最好的方法是指定每平方英尺所需的覆盖量。

Optional Coverages

制造商提供的WTW的最终要素涉及可选的覆盖范围。例如，大多数制造商不包括过度风速和基本保修范围的覆盖范围。而是收取额外费用，将其包括在保修范围中。为了避免意外的覆盖差距，最好从规范中包含的任何制造商那里索取WeatherTight保修示例文件。

Summary

那么，天气紧张的保修值得额外费用吗？只有您和您的主人才能决定。当您考虑问题时，请记住这一点：正确安装的金属屋顶不会泄漏。因此，作为我们行业中最强大的认证培训的制造商，我们希望看到您节省保修资金，而是在规格中包含一个紧密书面的承包商经验部分。但就像在新的冰箱或汽车上购买扩展保修一样，这确实是一个个人决定。

Frequently Asked Questions:

1.我是否需要预先批准我的项目以确保有wtw可用？

是的。Pre-approval is required during the bidding stage and must be completed before any materials are ordered or installation begins.

2.如果是这样，预批准过程是什么？

Submit roofing specifications and drawings (architectural preferred) via email towtw@beplay苹果版手机免费下载mcelroymetal.com

3. Are installers required to complete a certification process before a warranty will be issued?

所有单一来源都需要承包商认证，无维修限制（NRL）保修级别。此外，如果规格要求认证承包商，则需要认证，无论保修类型如何。

4. What are the inspection requirements for a Weathertightness Warranty.

The number and timing of inspections will be set during the pre-approval stage based on the building complexity and warranty requirements. The guidelines will be communicated on the returned pre-approval form.

5. Are penetrations included automatically?

No. Coverage for penetrations must be requested during the pre-approval stage and carries an additional cost.

6.“联合”和“单源保修”之间最大的区别是什么？

“单一源保修”旨在保护所有者免受安装程序的安装错误。从安装者的第一天开始，制造商就承担了“单一源保修”的覆盖范围，安装人员负责使用“联合”保修的前两年。

7. Is a review of shop drawings required?

是的。在订购任何材料之前，必须由我们的WeatherTightness保修部门提交和批准。图纸可以通过电子邮件提交给wtw@beplay苹果版手机免费下载mcelroymetal.com. If requested, McElroy Metal will produce the shop drawings for an additional fee. When McElroy Metal prepares the shop drawings, the review step is automatically incorporated and no additional steps are required by the installer.

8. What is the process when project specifications require a “certified” and “qualified” installer?

Material cannot be ordered until both the certification and qualification processes have been completed. Learn more about our“certification”program here and contact your local McElroy Metal representative for assistance to become a “qualified” installer.
