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.

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.

In most applications over asphalt shingles, our metal roofing can be applied over the old roof with 30lb felt underlayment or 1'x4' lathing boards installed between the existing roof and the new metal roof. This saves money and time. In addition, because there is no old roof to remove, landfill space is spared, helping to protect our environment.

Murray Shaw Inc. highly recommends the removal of the old roofing material before installing new asphalt shingles. The removal allows a professional to inspect the condition of the existing wood deck and all related roofing components to find any defects so that they can be fixed. Once all repairs are done, new shingles can be installed evenly and effectively.

Rustic Shingle is designed to be installed directly over worn out asphalt, fiber glass or wood shingle roofs to provide long lasting, weather tight protection. This eliminates the time, cost and mess a complete tear-off would require. The light weight of aluminum does not add any significant weight load to the house, unlike most other products. However, in same rare cases the old material may need to be removed to allow a secure installation of Rustic Shingle.

Note that the weights for cedar, clay and concrete products are all dry weights. All three-product categories weights increase when wet .

The system can also be installed on a bracket on a south facing wall, close to the bathrooms. However, the installation is difficult and leads to extra cost. The fixing of the system to the bracket should be proper. Access to the system for repairs should also be ensured. Cost of hot water distribution piping could be reduced in such installations as the system will be close to the use point.

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.

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)

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.

Your Rustic Shingle dealer can determine if your roof, like most, is suitable for a Rustic Shingle roof-over.

Yes, this is entirely possible. Temperature control is the issue. You can use one of our heat exchanges to change the steam to hot water. Then you can use a mixing valve to control temperature of the hot water. You may want to consider the use of a safety control.

Basically, a sunroom is an addition or an enclosed porch or patio area designed using windows and doors to admit a large amount of sunlight. Sunrooms are often referred to as solariums, conservatories, patio rooms, garden rooms, atriums, all season rooms, screened rooms or patio enclosures.

PV panels can be removed for service of the system and your roof. If need be, the entire system can be removed from the roof.
