最佳屋顶
We will be putting up Timberline GAF 30 roof shingles for a Net Zero new construction. Our builder wants to put them up now.. but should we first be putting up the PV solar panels brackets up first? And can you recommend web sites for beautifully installed PV panels? And if pretty much most of the FRONT side of the house (east roof) will be covered with PV panels.. do we need roof shingles underneath? Also open to a metal roof.. but too expensive!.. unless we can just do sections to hold the panels. Thanks for your advice!

站立的接缝金属屋顶的优点是它会超过光伏，因此您无需在重新屋顶时卸下面板，并且面板可以快速且防水贴在凸起的接缝上。
您是说要在朝东的屋顶上安装PV吗？PV应该大致面对赤道。
The roof must be waterproofed before PV panels are installed. The most aesthetic installation is one that can't be seen (or hardly), such as as PV shingles or thin film PV adhered to a standing seam metal roof.
如果要在东部屋顶上朝南的面板安装，则无法使它们看起来像是令人震惊的东西，因为面板必须朝南倾斜。
屋顶安装的光伏可能会提供更好的曝光，具体取决于现场，但需要用水密封下面的屋顶和穿透屋顶的接线。一个不太令人讨厌的装置是太阳追踪器上的地面单元，例如所有地球可再生能源（All Sun Trackers）的出色完全独立的GPS/无线控制单元。
但是，在屋顶安装的选择中，夹紧站立的接缝屋顶是迄今为止最好的。在我花钱上花钱之前，我会投资耐用的屋顶（净零是房屋的误导目标 - 极端的能源利用减少是一个更具生态负责的目标）。
Important questions here are who is responsible for the PV system to roof detail? who is responsible for installing it? and who is responsible if the roof leaks?
Your builder wants to roof before the PV installation? Maybe they are trying to avoid liability. How can you roof before the installation and flash properly?
Either the GC or the architect, in the interest of the client, needs to coordinate the proper roof install of a PV system. Be careful if the solar contractor isn't a sub of the GC.
I've seen projects where the solar contractor was brought in by the architect or the client. It wasn't defined up front who would actually install the brackets to hold the PV panels and it therefore didn't appear in either the GCs bid for the solar contractors bid. You don't want to be in this scenario.
JChestnut……我的邻居有一个非泄漏solar install in snow country. Solar company said have your roof reshingled then they come in after no problem.
而且没有问题。
again.. I have to mostly agree with RR though
卡伦，
1.如果这是新结构，为什么在东侧的PV阵列？用南屋顶设计房屋会更有意义吗？
2.尽管您的标题是“ PV面板最佳的屋顶”，但听起来好像您已经决定使用沥青带状疱疹，无论该选择是否是“最好的”。没关系 - 带状疱疹会起作用。但是它们不会像站立式金属那样持续。
3. If you want your PV array to be unobtrusive, the modules will probably be installed parallel to the roofing, with an air space of a few inches between the modules and the roofing. The air space is necessary and useful; it helps keep the modules cool.
当然，安装平行于屋顶的模块在向东的屋顶上实际上无法正常工作。
4.您的光伏安装程序绝对应与屋顶机协调。您的光伏模块可能会安装在附着在需要牢固结构附件的支架或管道上的铝制导轨上。这些支架或管道需要闪烁，应将闪烁与木屋顶集成在一起。
Thank you for your responses. Keep on hearing that standing seam is better than asphalt shingles. How long will the asphalt shingles last? We're looking at the 30 yr ones? And what's a good metal company to look at? Thanks again. Sorry.. meant to say South facing roof in my previous question.
卡伦，
沥青木瓦的保修是营销头，而不是对使用寿命的预测。15或20年后，大多数沥青木屋顶被更换。在许多情况下，出于美学原因，藻类的生长变得如此难看，以至于房主更快地取代了其沥青木屋屋顶。
I have to disagree with Martin once again. The warranties on asphalt shingle roofs almost exactly track the expected life and are generally proportional to the amount of material thickness.
Most custom builders today are using what are called architectural shingles, or laminated shingles, both for the less uniform look and for the longevity. You can get shingles with up to 50 year warranties, but they'll cost you almost the same as a good standing seam metal roof.
我不知道金属制造商在质量方面彼此之间有很大不同，但是屋顶工会使用不同的金属厚度。大多数屋顶工更喜欢26克金属，因为它更容易弯曲，但是更好的屋顶工使用24克，不会像较薄的材料那样皱纹，但需要机械制动才能弯曲。
I forgot to add that algae and moss growth on a shingled roof is usually secondary to organic debris collecting on the roof from nearby trees. With no trees, a steep roof slope and regular rain washing, there's generally no algae. The algae feeds on the debris and the moss feeds on the algae.
You can get algae-resistant shingles that contain copper granules. Shingles are warrantied for up to 20 years against algae growth.
