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.

The exact composition of Enviroshake® is a proprietary trade secret. It is what is commonly known as a composite material that contains plastics, fibers, and tire derived rubber. There are also components that protect it from UV degradation and provide the necessary colouring to replicate the look of cedar shakes.

Yes. Springhouse Shingles can be installed over your existing asphalt roof thereby eliminating expensive tear off and disposal fees.

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.

Yes. You can apply new shingles over existing shingles, but it depends on the condition of the roof and city ordinance. If the roof has one layer of shingles that are laying flat and the deck is in good condition, the existing shingles typically do not have to be removed. Check with local officials to make sure that building codes are being followed.

Enviroshake® is currently offered in only one colour. It starts out as a brownish grey colour and converts or “weathers” to a silver-grey colour that closely resembles a real cedar roof.

Enviroshake® is recommended for roofs with a pitch of 4/12 or greater. Please consult Technical Support at 1.866.423.3302 or info@enviroshake.com if your roof slope is less than 4/12.

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.

Yes, you can install just the SELinux modifications on an existing Linux system or you can install a Linux distribution that already includes SELinux support. SELinux consists of a SELinux-enabled Linux kernel, a core set of libraries and utilities, some modified userland packages, and a policy configuration. To install it on an existing Linux system that lacks SELinux support, you must have the ability to compile the software and also have other necessary system packages.

A number of factors come into play in making this decision. Older shingles tend to cup as they dry out and age. The new layer will follow the contour of the existing shingles which may cause your new roof to look bumpy or uneven. Also, the existing rows of shingles must have been run straight when installed. Again, the new layer will follow the old pattern and may lead to a visually unacceptable appearance.

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. Request Fabral's Technical Bulletin #721 for additional information.

The 4 best months in the year, for installing asphalt shingles, are May, June, September and October. However, most roofing contractors consider the season, from mid-March to mid-December. During very hot and humid weather [July & August], we sometimes have to pull the crews away from sites, by noon hour. Otherwise, the conditions are not healthy and the new shingles may be damaged, as they get very soft.

A 2nd layer of shingles can be installed, if certain criteria are followed. The removal of the existing hip and ridge shingles, cutting-flush the eave and gable shingles, and installing an Eave Drip Edge are all required, to have a warranty from the manufacturer. By the time you do these things, and pay for the resulting labour - you might just as well do the project in a professional way.

Yes. Although most people who get shingles develop immunity to the varicella zoster virus and don't get it again, about 4% of people will have another outbreak in the future. When shingles does recur, it is often in people with weak immune system due to factors such as HIV infection, cancer or some cancer treatments or certain medications taken after an organ transplant.

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.

No. Shingles occurs only when the virus that caused chicken pox, which has stayed in the body for many years, becomes active. You cannot get shingles from someone else. You can only get it from the varicella zoster virus in your own body.

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.

Yes, but the preferred method is removal. The Uniform Building Code allows two (2) roofs on commercial (flat) buildings and three (3) roofs on residential(steep) buildings. Removal allows for inspection of the substrate, and the elimination of any wet, rough, and/or unstable existing materials.

While it is always easier to install these systems in new construction environments, it is very possible to install the system in an existing home. All homes are different, and the degree of difficulty is dependent on what sub-systems you intend to automate, and the layout of your home.

Existing homes can easily have insulation installed in most ceilings and under timber floors, space permitting. However, walls and vaulted ceilings can only be insulated during the recladding or replastering process.

Yes, when you have an electrical interface for the functions you want to control, provide that information to DWS and we can guide you through the process. B. In the event you have no electrical interface, DWS can suggest retrofit kits for your specific application.

Yes, the ChiliBox can be installed on a network that has existing hardware. However, the ChiliBox is intended to be the gateway device, which means that it would directly connect to the Cable/DSL (i.e., broadband) connection before any other hardware. If the ChiliBox is installed behind another router (e.g., Linksys, D-Link, Netgear) then certain ChiliBox features will not work.

No. The varicella zoster virus causes only chicken pox and shingles. It does not cause cold sores or genital herpes.
