Installing a roof over the top of an existing roof is generally acceptable under these guidelines: 1) A building cannot have more than two roofs; 2) No wet insulation can be left in place; 3) The roof structure must be able to handle the additional roof load; 4) The new roof must be attached to the roof deck to meet wind loads (it is not generally acceptable to adhere the new roof to the old roof)

Multiple roofing layers tend to decrease a roof's resistance to hail. Make sure to check local building codes, as some building codes and ordinances restrict the number of roofing layers a house may have. Another issue to consider with wood shingles when applying a new roof over the wood shingles is possible fungus problems. Installation of metal products over existing wood shingles is common as long as proper cuts for ventilations are observed.

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

For pre-existing conditions we recommend Shingle Shield Roof Cleaner, which is specifically designed to clean roofs prior to application of the roof protector strips. Other cleaning solutions may not be effective against these organisms, and may harm your roof or plants.

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.

Yes in some cases. But you should have a professional roofer inspect the current conditions of your existing roof.

If you are committed to your home for years into the future, a metal roof will offer you much greater value and a lower life-cycle cost than the most common and inexpensive roofing products, even though the initial cost seems higher. This is because you will not need to replace this roof for 50 years or more, whereas on average, asphalt shingle roofs are being replaced every 15 years. We like to say that a metal roof is "the last roof you'll ever have to buy."

the GRP roof systems we use lend themselves to over-roofing (providing the existing deck is in serviceable condition) it is not always necessary to strip the existing roof covering and decking. An initial site survey should establish whether the existing deck should be replaced as per building regulations.

Absolutely, NO!!!!! If you cover your roof for any amount of time, moisture will build up between the leaves and your tarp, causing the leaves to quickly rot and grow mold. Once the leaves begin to rot, they will fall apart relatively quick. However, you can cover your roof for a few days or so if you know a major storm is expected in your area. Doing this will actually help prolong the life of your roof.

Most individual and family health insurance policies limit coverage for pre-existing conditions during the first nine to twelve months of coverage. However, the pre-existing condition exclusion period is waived to the extent that the applicant has "qualifying" prior group coverage. This is a government-mandated requirement, though the health insurance company can still deny the application of someone whose health does not meet the insurance company's underwriting requirements.

In most cases a metal roof can be installed over composition roofing materials. The condition of the roofing substructure will be a factor and the building codes in your area will dictate the number of roofing layers allowed. Because of its light weight, relative to all other roofing systems, many local codes will allow installation of a metal roof over multiple roofing layers where other systems would be prohibited.

A:A PV system can be installed on any well-structured roof. Typically asphalt shingles are easiest to work with, while slate is the most difficult. If your roof is older and needs to be replaced in the very near future, you may want to replace it at the time the PV system is installed to avoid the future cost of removing and reinstalling your PV system. PV systems are also available that integrate PV cells into the roofing materials themselves.

with any roofing product, the best procedure to use when re-roofing is to tear off the existing roof and use industry approved underlayments to assure the best performance over the life span of the roof. But this can be done. It will not affect the material warranty, but it will affect the wind and fire ratings. So usually the benefits of tearing off out weigh going over an existing roof.

One of the benefits of steel roofing is that is lightweight, which allows it to be installed over existing roofing material. Local building codes and your roofs substructure integrity must be addressed to reveal this answer.

The largest 9” ZMesh system (zone) will cover approximately 425 square feet. Multiple zones are sometimes required for larger projects.

Medical costs abroad can be very expensive and without adequate insurance cover you could be left severely out of pocket. We recommend that all travellers are insured on the same travel insurance policy. Gaps in cover could arise if separate policies are purchased (e.g. some policies will exclude pre-existing medical conditions of persons travelling with you).

Yes, in most instances, pre-existing conditions are covered. Please call Member Services with your specific situation.

It depends on the type and size of the greenroof. Most homeowners could check a flat or low pitch greenroof. A roofing professional should if it is too large or intensive – you can include a maintenance agreement of at least twice per year with the greenroof contractor/greenroof company. Or you can work out an arrangement with the roof maintenance staff of your building.
