Frequently Asked Questions

 The architect will require UL, ASTM, or FM rating. 

As a general rule, most metal roofing should not be placed on a slope lower than a 3/12 pitch. The exception to this rule would be to use the ASP-ML200 panel, which can be applied on a roof down to 1/2″/12 slope. 

 Any of the profiles can be applied to a solid deck substrate. Some of the panels can be utilized on open purlins, such as the 24ga. ASP-SL175, 18″wide panel that can span up to 4’0″ and the 24ga. ASP – ML200 16″ wide panel that can span up to 5’0″. Other panels also have spanning capabilities please call for more information. 

All of the panels provided by ASP, Inc., unless otherwise noted, are based on utilizing GALVALUME as a base metal. This material has a proven track record that shows it to be one of the best roofing material available today. Literature and testing for GALVALUME sheet products are available upon request. 

The standard in the standing seam metal roofing industry today is KYNAR. KYNAR is added to the paint resin to kill UV light which destroys the integrity of paint causing fading, chalking, blistering, peeling and early failure of the paint system. All of the paint finishes provided through ASP, Inc. will have a 70% KYNAR 500 finish unless otherwise noted. Special colors and finishes are available but generally have minimum quantities and longer lead times than standard colors and finishes. 

This will dictate the types of panels utilized or the clip spacing may be changed due to roof heights. It may also be useful to know if the panels will be craned to the roof as that may effect the type of packaging needed for shipping. 

 This requirement will determine the type of packaging, freight, vehicle and whether the panels may require site forming. 

This may sound like a strange question but often panels are utilized for walls, mansards or equipment screens where water tightness is not the main factor but looks are of higher consideration. Generally a snap lock style panel will be better suited to this type of application rather than a mechanically seamed panel. Also accompanying details will be different when you get ready to price the job. 

With exceptions,if the customer is a first time installer the snap lock style of standing seam roofs are the most user friendly standing seam panels to learn on. They do not require the finesse that a mechanically seamed panel requires or the rental and use of an electric seamer. 

The roofer/contractor is responsible for ALL field measurements. ASP, Inc. will not be responsible for any field measurements. Also, blue prints are not a reliable source for actual panel lengths. The roofer/contractor will be responsible for all measurements and quantities of materials ordered. It is generally advised that when ordering panels at least one extra panel of the longest length required be ordered just in case a panel is damaged or incorrectly cut. Setup charges, freight and delaying a project completion are generally much more expensive than building an extra panel into a job. 

Depending on the job and/or contractor shop drawings maybe required. For a nominal charge ASP, Inc. will provide shop drawings. These drawings must be approved by the architect and/or the contractor before production of details will be manufactured. On occasion they will be provided free of charge dependent on the size of the project. Generic drawings of details will be available to the roofer/contractor upon request. 

Every metal roof installation, no matter how simple, is custom made. The roof panels and details are manufactured to the specific needs pertaining to each individual project. Many times a “standard” detail will not work and it is much better to be sure all the details will fit together before materials arrive on site. Some of the detail validation may seem redundant to the installer but we at ASP, Inc will not manufacture materials until the installer/contractor has signed off an all the details for a particular project. This does two things – one is that the installer can be sure he/she is getting the correct details for his job and secondly he/she will have the correct quantities to complete his project without delays. 

The contractor/installer is responsible for unloading materials when they arrive on the job site. Panels are crated for lifting either by crane or forklift. On longer panels spreader bars on cranes or two forklifts may be necessary. Panels should be stored on a pitched slope to allow water to drain off them freely. 

All masking MUST be stripped off panels and details as soon as they are installed. Also keep direct sunlight off all masking – direct sun light can bake strippable film on panels & details making removal virtually impossible.
