Since metal weighs only 1/3 as much as shingles, you can often attach metal panels without tearing off your existing shingle roof. This eliminates the cost and problems of disposing of the old shingles. The best way to do this is to attach 1" x 4" or 2" x 4" furring strips at 24" o/c parallel to the eave and ridge. Check local codes to determine if tearing off shingles is required in your area.

It is possible, but we recommend removal of the existing shingles to ensure the shingles perform to the manufacturer's specifications and to keep your manufacturer's warranty intact. Installing new shingles over the existing can trap moisture from the old shingles and cause premature deterioration of the new shingles.

We include installation guidelines with each order, but metalwork and roofing installation experience are a must to achieve the protection your home deserves. We suggest hiring an experienced roofing crew locally, or you can hire an expert Summit Roofing crew.

Different jurisdictions have different code regulations but generally speaking, Enviroshake® can be installed over one layer of existing asphalt shingles, provided the roof is structurally sound underneath. There is considerable cost savings since there would be no additional cost for removal and disposal of the shingles. There are considerable environmental benefits to this as well because the old shingles need not be put in a landfill. No.

You may use either screws or nails-both color matched to the color of your roof. Screw fasteners are preferred over nails for superior pullout resistance and weathertightness. Screw fasteners are designed to go into the flat part of the panel. Nails MUST GO in the high rib of the panel. Fasteners are typically spaced 24" o/c.

Good idea in snow country, or if you're in an area where water is scarce. Think about a "rain catchment" system with a metal roof, gutters, and a holding tank.

Not only do the metal inserts make the panels stronger (approximately 2.6 times), they also enhance the looks of the grooves. Metal inserts are available in: mill aluminum, gold anodized, black anodized, and painted colors. The metal inserts need to be installed at the factory. The grooves are cut slightly larger to accept metal inserts. To gain the maximum strength the panels should be glued and screwed to the stud-wall.

Building codes require that panels thinner than 1/4" be installed over a non-combustible backer over studs. Georgia-Pacific Western Vista panels, 1/8" and 3/16" hardboard; 1/8" and 5/32" Mount Vernon? and StyleLine? wall panels always should be installed over a solid, non-combustible backing such as gypsum wallboard. Please see installation instructions (PDF: 273KB/8pgs) for more detail.

You should always replace your wall, chimney, skylight, valley, plumbing pipe boot and any other flashings when installing a new roof. Make sure that the life expectancy of the flashing metal is the same life expectancy as your new shingles. The reason is that your roof is a system of components that work together to keep your roof from leaking. If you leave any one component out you are at risk of your roof leaking in that area.

Rudraksha can be worn in anything according to the person's faith. But it is best if it is worn in a metal be it silver or Gold or copper or Panchdhatu. When worn in metal the Electromagnetic powers of the bead increases. Thus increasing its effect.

It depends on the condition of the old insulation: if it is wet or in very bad shape, it is better to remove it. Wet insulation creates fungus and mold, which can be very harmful to people. Furthermore, most insulations that absorb water will have lost much of their insulation value.

No. Standard lead pencils, or those made with graphite, will accelerate the corrosion of the metal near the mark. You can use masking tape and mark on the tape to prevent corrosion -- plus, masking tape is easier to see. We cover more than 1,000,000 square feet (every year) with metal and canvas outdoor covers, we have any option you're looking for, along with the name and brand you can trust.

The paint finishes used on our panels are the highest quality. We start out with a high-tensile steel. We then coat it with a Galvalume 55% zinc, 45% aluminum coating. They are next pre-treated with primer, and then finally coated with a high quality baked-on enamel paint system.

Yes. The extra support downslant arm is available for extra support of the plated shelf bracket. It works with the 10" and 12" shelf bracket and gets attached via set screw to the underside of the bracket with the opposite end fitting into a groove below the bracket - for added support.

No. All of our panels are formed at the job site to the exact measurements of your roof. This means that there will be no breaks in the length of the panel which can cause complications during instillation.

Ceramic tile can be bonded to ceramic tile with a polymer modified thinset BUT your installation will only be as good as the weakest tile in the old installation.

Improper air filtration... keep your air filter clean and oiled, upgrade to a high performance air filter if you run in areas with excessive dust. You'd be amazed at the engines that we see come in with dirt all over the inside of the engine. See the KITS--> "Why you need to care for your engine" link. Running too lean... adjust the carb as often as needed so that you see a nice trail of smoke at FULL SPEED.

If an allocation fails in the young generation and the object is a large array that does not contain any references to objects, it can be allocated directly into the old generation. In some select instances, this strategy was intended to avoid a collection of the young generation by allocating from the old generation. There is a flag (available in 1.4.2 and later) l-XX:PretenureSizeThreshold=<byte size> that can be set to limit the size of allocations in the young generation.

Yes. You can boot the Debian installation system from a set of files you can download from our FTP site and its mirrors. You can download a small CD image file, create a bootable CD from it, install the basic system from it and the rest over the network. For more information please see http://www.debian.org/CD/netinst/. You can also download even smaller floppy disk image files, create bootable diskettes from them, start the installation procedure and get the rest of Debian over the network.
