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.

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.

NRCA recommends galvanized steel or the equivalent corrosion-resistant roofing nails for asphalt shingle installation. Also, verify the governing building code requirements and what the shingle manufacturer recommends. NRCA suggests the amount of attic ventilation be balanced between the eaves and ridge. The intent of a balanced ventilation system is to provide nearly equivalent amounts of ventilation area at the eave/soffit and at or near the ridge.

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.

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.

In the United States, asphalt shingles are categorized as either organic-based or fiberglass-based. Organic-based asphalt shingles are manufactured with a base (also termed mat or substrate) made of various cellulose fibers, such as recycled waste paper and wood fibers. This organic base is then saturated with a specially formulated asphalt coating and surfaced with weather resistant mineral granules.

Shingles -- also called varicella-zoster -- is a painful skin disease caused by a reactivation of the chickenpox virus. It is distinctive because it affects only one side of the body. The early signs of shingles usually develop in three stages: severe pain or tingling, possibly itchy rash, and blisters that look like chickenpox.

Sometimes it is nice to place layers in groups. It makes them easier to organise when you have lots of them. It also means you can easily apply the same effect to lots of layers, without directly affecting those layers. Long story short, it makes life easier. This will be much easier to program once GEGL has been integrated into GIMP.

Answer: Yes, but you need to buy an optional 2nd power supply mounting kit. The part number is PSKIT78. Two independent ATX power supplies in the same computer case are different from Redundant power supply. The redundant power supply is for mission critical applications. One power supply goes down, the other power supply will take over automatically and the system can keep running without interrupt. Normally, two independent ATX power supplies system is for non-mission critical application.

for a T56 in my 72, it was pretty easy. I bought it connected to an LT1 from a 97 WS6 that was rolled at 3422 miles (kinda makes you feel sick, huh). I thought it was going to take a lot more work than it has, but it was really fairly simple. The car was originally auto, but I had already converted it to a manual. The trans tunnel needed only minor massaging and I had to move the cross member back some. The driveshaft had to be shortened about 2-3 inches.

IKO agrees with and supports the ARMA position that nails are the preferred method of fastening asphalt shingles due to their superior holding strength. The following fastening tips apply to most IKO shingles; (check specific product application instructions for further information): Correctly place and position fasteners below the sealant strip, but above the cut-out on three tab shingles, and in the nail line on laminated shingles.

No, absolutely not. There has been significant testing on this issue and it has been proven that a Radiant Barrier installed in a residential attic will have not have any detrimental effect on the shingles.
