Gutter System Installation Standards Product Specification Property of: Spectra Metal Sales Gutters and Leaf Protection Introduction A Rain Gutter System starts with a trough, called a gutter, which collects rainwater from the roofline of a house and diverts it away from the structure, using elbows and downspouts. • The purpose of this diversion is to prevent water flow off the roof edge which can cause structural damage over time to the walls and/or foundation of a house. • The gutter system is more important to the exterior of your home than the actual paint, siding, or even windows, because it protects your home from rot, mold, mildew, and flooding. • This water damage, without a gutter system, occurs slowly, spreads quickly, and is unnoticeable until the damage repair is substantial. • For your gutter system to work properly, it must be able to empty out the water faster than it fills up. In order to ensure the proper flow of water, a few are vital to the success of the overall gutter system: 1) Seamless gutters 2) Gutter and downspout sizing 3) Slope or pitch of gutter 4) Downspout placement 5) Keeping the gutters debris free 6) Using quality parts and accessories 2 Gutter Specifications Scope of Guide A) The Rain-carrying system consists of all necessary components to complete installation with products manufactured or endorsed for use by Spectra Metal Sales. System Components A) Gutters shall be made of 3105-H24 aluminum and shall be continuous and seamless with a minimum thickness gauge of .032” or .027” (+/- .002” nominal). B) All pre-painted components will have an approved SMS Finish and Color. C) Prior to painting, all metal shall receive a pre-treatment to assure for maximum paint adhesion. The exterior finish shall be of a baked on enamel, one-coat system applied in a continuous process in a single operation, comprising a high- performance linear topcoat. The inside of the gutter shall be finished with a wash-coat finish. D) Downspouts, Elbows, Miters, End caps shall be made of 3105-H24 aluminum with a minimum thickness gauge of .019” (+/- .002” nominal). E) Sealant/Caulking - Seam Sealer, OSI ProSeries, Ruscoe, Geocel F) Hanging system for the standard K-style system will be the SMS Hidden Hanger with Screw attached for size as necessary. G) Lock-On Gutter Screen from SMS, sized as necessary. H) Solid Gutter Cover from SMS, to be the Leaf Protection Panels in an approved SMS color. I) All accessories used with the SMS Rain-carrying system will be procured from a SMS distribution or manufacturing facility. Installation Guidelines A) Gutters shall be formed onsite from SMS gutter coil, which has been procured from an approved SMS distribution point. B) Gutters should have a minimum pitch of ¼” for every 10 feet of single section. C) Downspouts should be installed every 40 feet. D) Outlets and Elbows will be screwed or riveted to the adjoining section for security. E) Miters will be screwed or riveted to the adjoining section with an approved sealant. Field cut miters, Box miters, and Strip miters are all acceptable forms of installation. F) Hangers will be spaced a maximum 24”-36” inches apart on any continuous gutter run for strength and stability of the overall system. 3 Gutter System Installation Instructions 1. The first thing to do is determine how much material you will need. Obtain the linear footage measurements of the roofline. Also, decide where you want your downspouts. Be sure to practice ladder safety. 2. Begin measuring the roofline where the gutter will be installed, adding together the lengths of each fascia. Take the measurement from the outer edge of the shingle. Mark the measurements and make an outline on graph paper. Next, mark the locations of the downspouts with an "X.". Plan on one downspout per gutter per 20 foot run. Finally, measure and add the heights from the ground to the roofline in the locations where the downspouts will go. 3. If you are replacing an existing gutter system, once the old system is removed check for rot along the fascia board. If there is damage, replace the fascia plate or fascia cover over it or just replace the fascia board. 4. For every 10 feet of gutter, you need at least a quarter-inch of drop. This will ensure that the water flows towards the downspout. 5. Begin by driving a nail into the fascia at one end of the gutter-run wall a half-inch below the top of the fascia. Stretch a mason's line from the nail. To properly align the slope (using a line level on the mason's line) drop one end of the line a quarter-inch for every 10 feet of fascia length, then mark that point with a pencil. Snap a chalk line from the marks to show where the top of the gutter will be attached. 6. Remember to pitch longer runs toward an outlet at either end, as opposed to just one end. The gutters should always be pitched away from the front valleys and towards the corners. 7. Using the chalk line to keep the gutters flush with the slope line. Remember to slope towards the outlet and downspout. Continue this process with all gutter sections. 8. The end cap section is the piece you will start with when applying the gutters to the fascia. Working from the end of the fascia, use hidden fasteners to attach the gutter to the fascia. Hidden fasteners are slipped into the gutter run, and then the gutter is screwed into the fascia with a drill and screws. Hidden fasteners are placed every 24 inches along the gutter run. 4 9. To attach a downspout, assemble an elbow and a short length of downspout to carry the run to the wall. Anchor the downspout to the wall with two brackets while attaching the top of the downspout into the exposed outlet. Attach another elbow at the bottom of the downspout to divert water away from the foundation. Place a splash guard underneath it to keep water from eroding the soil. 10. Check all joints and seams to verify the proper amount of sealant has been applied to prevent potential leaks. 11. Clean all scrap metal and trimmings from the jobsite. 5 Letter of Certification 5 Inch Speed Screw Hanger 5SSH Spectra Metal Sales, Inc. is a member of the National Coil Coating Association and uses the NCCA’s standards as guidelines for physical testing. • The Aluminum used is alloy 3105-H24 or 3105-H25 which meets the specifications set forth in the “Aluminum Standards and Data 2006” published by the Aluminum Association.
