Like the man said This is very old and I did it for an experiment - the roof of my own house in fact - and haven't reused it but it does give a hosted standing seam effect and I think from memory it looks about right in section too.

For instance, the spacing of the seams on a standing-seam metal roof will affect the building's overall scale and should therefore match the original dimensions of the seams. Many older roofing practices are no longer performed because of modern improvements. Research and review of specific detailing in the roof with the contractor before beginning the project is highly recommended.

For example, one early craft practice was to finish the ridge of a wood shingle roof with a roof "comb"—that is, the top course of one slope of the roof was extended uniformly beyond the peak to shield the ridge, and to provide some weather protection for the raw horizontal edges of the shingles on the other slope.

If the "comb" is known to have been the correct detail, it should be used. Though this method leaves the top course vulnerable to the weather, a disguised strip of flashing will strengthen this weak point. Detail drawings or a sample mockup will help ensure that the contractor or craftsman understands the scope and special requirements of the project.

It should never be assumed that the modern carpenter, slater, sheet metal worker, or roofer will know all the historic details. Supervision is as important as any other stage of the process. The use of the historic roofing material on a structure may be restricted by building codes or by the availability of the materials, in which case an appropriate alternative will have to be found. Some municipal building codes allow variances for roofing materials in historic districts.

In other instances, individual variances may be obtained. Most modern heating and cooking is fueled by gas, electricity, or oil--none of which emit the hot embers that historically have been the cause of roof fires. Where wood burning fireplaces or stoves are used, spark arrestor screens at the top of the chimneys help to prevent flaming material from escaping, thus reducing the number of fires that start at the roof.

In most states, insurance rates have been equalized to reflect revised considerations for the risks involved with various roofing materials. In a rehabilitation project, there may be valid reasons for replacing the roof with a material other than the original. The historic roofing may no longer be available, or the cost of obtaining specially fabricated materials may be prohibitive. But the decision to use an alternative material should be weighed carefully against the primary concern to keep the historic character of the building.

If the roof is flat and is not visible from any elevation of the building, and if there are advantages to substituting a modern built-up composition roof for what might have been a flat metal roof, then it may make better economic and construction sense to use a modern roofing method. But if the roof is readily visible, the alternative material should match as closely as possible the scale, texture, and coloration of the historic roofing material.

Asphalt shingles or ceramic tiles are common substitute materials intended to duplicate the appearance of wood shingles, slates, or tiles. Fire-retardant, treated wood shingles are currently available. The treated wood tends, however, to be brittle, and may require extra care and expense to install. In some instances, shingles laid with an interlay of fire-retardant building paper may be an acceptable alternative.

Copper-coated steel is a less expensive and less durable substitute for sheet copper. The search for alternative roofing materials is not new. As early as the 18th century, fear of fire caused many wood shingle or board roofs to be replaced by sheet metal or clay tile.

Some historic roofs were failures from the start, based on overambitious and naive use of materials as they were first developed. Research on a structure may reveal that an inadequately designed or a highly combustible roof was replaced early in its history, and therefore restoration of a later roof material would have a valid precedent.

In some cities, the substitution of sheet metal on early row houses occurred as soon as the rolled material became available. Cost and ease of maintenance may dictate the substitution of a material wholly different in appearance from the original.

The practical problems wind, weather, and roof pitch should be weighed against the historical consideration of scale, texture, and color.

Sometimes the effect of the alternative material will be minimal. But on roofs with a high degree of visibility and patterning or texture, the substitution may seriously alter the architectural character of the building. It may be necessary to carry out an immediate and temporary stabilization to prevent further deterioration until research can determine how the roof should be restored or rehabilitated, or until funding can be provided to do a proper job.

A simple covering of exterior plywood or roll roofing might provide adequate protection, but any temporary covering should be applied with caution. One should be careful not to overload the roof structure, or to damage or destroy historic evidence or fabric that might be incorporated into a new roof at a later date.

In this sense, repairs with caulking or bituminous patching compounds should be recognized as potentially harmful, since they are difficult to remove, and at their best, are very temporary. The architect or contractor should warn the owner of any precautions to be taken against the specific hazards in installing the roofing material.

Soldering of sheet metals, for instance, can be a fire hazard, either from the open flame or from overheating and undetected smoldering of the wooden substrate materials. Thought should be given to the design and placement of any modern roof appurtenances such as plumbing stacks, air vents, or TV antennas. Consideration should begin with the placement of modern plumbing on the interior of the building, otherwise a series of vent stacks may pierce the roof membrane at various spots creating maintenance problems as well as aesthetic ones.

Air handling units placed in the attic space will require vents which, in turn, require sensitive design. Incorporating these in unused chimneys has been very successful in the past. Whenever gutters and downspouts are needed that were not on the building historically, the additions should be made as unobtrusively as possible, perhaps by painting them out with a color compatible with the nearby wall or trim. Special problems inherent in the design of an elaborate historic roof can be controlled through regular maintenance.

The shape and detailing are essential elements of the building's historic character, and should not be modified, despite the use of alternative surface materials. Although a new roof can be an object of beauty, it will not be protective for long without proper maintenance. At least twice a year, the roof should be inspected against a checklist. All changes should be recorded and reported. Guidelines should be established for any foot traffic that may be required for the maintenance of the roof.

Many roofing materials should not be walked on at all. For some—slate, asbestos, and clay tile—a self-supporting ladder might be hung over the ridge of the roof, or planks might be spanned across the roof surface. Such items should be specifically designed and kept in a storage space accessible to the roof. If exterior work ever requires hanging scaffolding, use caution to insure that the anchors do not penetrate, break, or wear the roofing surface, gutters, or flashing.

Any roofing system should be recognized as a membrane that is designed to be self-sustaining, but that can be easily damaged by intrusions such as pedestrian traffic or fallen tree branches. Certain items should be checked at specific times. For example, gutters tend to accumulate leaves and debris during the spring and fall and after heavy rain.

Hidden gutter screening both at downspouts and over the full length of the gutter could help keep them clean. The surface material would require checking after a storm as well. Periodic checking of the underside of the roof from the attic after a storm or winter freezing may give early warning of any leaks.

Generally, damage from water or ice is less likely on a roof that has good flashing on the outside and is well ventilated and insulated on the inside. Specific instructions for the maintenance of the different roof materials should be available from the architect or contractor.

With these points in mind, it will be possible to preserve the architectural character and maintain the physical integrity of the roofing on a historic building. Much of the technical information was based upon an unpublished report prepared under contract for this office by John G.

London: Oxford University Press, This method comes with one major advantage: there are no seams. Even better is having no seams whatsoever! This deck area can be used for anything from being a casual place to relax, a place to host small parties or events, or a place to work out.

Just imagine taking your yoga mat out to the roof and meditating in the early morning! However, given the increased weight involved and the need to ensure a non-slip surface for guests, certain factors need to be kept in mind.

Most importantly, such a roof has to be able to bear the increased load and it has to remain completely waterproof. Finally, all this must be done at a reasonable price. A PVC membrane for a roof deck will be completely watertight, durable and long lasting.

If all this is done properly, it will result in a beautiful roof deck that you can enjoy for years. And, as noted earlier, you also have the choice of using a special slip-proof PVC membrane layer as a surface layer as well. In the end, this could end up being the more cost-effective choice for your roof deck. Obviously, homeowners and business owners have choices when it comes to protecting their roofs or flat roof replacement options.

In general, there are seven important factors to keep in mind when comparing the choices:. For most homeowners, the two key factors to keep in mind are cost and performance.

A synthetic underlayment is the best choice as a state of the art barrier against water infiltration. You should always use a high quality underlayment in a valley condition or any other detail that is likely to be difficult to seal. A peel and stick type rubber underlayment is also recommended at the eave and up to at least 24” past the exterior wall in a northern climate to help prevent.
