Layover or re-roof? It's an important decision. When your existing roof becomes unacceptably deteriorated, the roofing product manufacturer will not honor their warranty. Blackhawk Roofing considers four things when evaluating whether we can re-roof over your existing roof:
Proper installation is essential to roofing system performance. Valleys and eaves are a weak point in your roofing system. They should be protected with metal or premium roofing felt, according to manufacturer's specifications and industry standards.
Blackhawk Roofing utilizes single-ply EPDM for commercial roofing projects. EPDM is classified as a Thermoset material, which means it is either fully-cured prior to being installed or that it cures during natural weathering after installation. EPDM roofs are single-ply membranes, meaning there is only one ply of roofing material, not multiple plies laminated together.
EPDM is a rubber material whose principal components consist of the compounds ethylene and propylene. A flexible rubber matrix forms when a small amount of diene is added to the mix. EPDM is available reinforced or unreinforced with both commonly used; it's also available in either a cured (vulcanized) or uncured (non-vulcanized) state. Vulcanized EPDM is commonly installed for roofing. Non-vulcanized EPDM is used for flashing.

Phase #1. This roof is a good example of the types of issues we often encounter in replacing an older roof. Blackhawk Roofing began a residential roof project on a house in the woods in Lincoln, Illinois. On first inspection, the roof had rock covering a rubber membrane. We swept all the rock off into a tractor bucket provided by the homeowner. After the rubber roof was removed (plus a layer of insulation board we encountered and also removed), we discovered a hot tar/rock roof layer with 2" insulation board. This was also removed. Two 30 cu.yd. dumpsters were required for all disposed material.
Phase #2. Existing decking was 5/8" plywood. Ten sheets of plywood had badly deteriorated due to leakage. Upon replacing plywood, we noticed there was no insulation between the plywood, and the drywall of the cathedral ceiling. To prohibit water temporarily getting into the house in the event of rain while the homeowner made a decision on insulation, we installed weather and ice shield on the entire roof. We also replaced the bad decking with 5/8" plywood. The roof is a 4/12 pitch roof, and the homeowner and Blackhawk Roofing concurred that this roof should be shingled.
Phase #3. The homeowner then contacted an insulation company, and received three options. The most cost-effective option was chosen: to have the roofing contractor insulate the decking, and then install another layer of sheeting. Blackhawk Roofing installed 1" ISO Board and 7/16" OSB, all nailed with 3" ringshank nails on 16" centers. We next put #30 felt down, and finally shingled the roof. All stone areas received new step-flashing and counter-flashing. Two critial flat areas received saddles built behind them, and rubber was installed for added protection. We also replaced two skylites.
Phase #1. Blackhawk Roofing began this commercial roofing project for the U.S. Post Office in Ashland, Illinois by removing the existing roof. We waited to start until we received a good weather forecast. Three layers of existing roofing were torn off. The two upper layers were rubber, with wet insulation between the layers. Below that was a layer of hot tar and gravel. This was also removed.
Phase #2. After removing the old roof, we discovered that the existing metal decking, installed on 60" centers with steel support beams, had rusted terribly. Due to the level of deterioration, the anchorage that the metal deck provided was compromised. We installed a 2x4" reinforcement on 24" centers, to provide attachment points for the new underlayment. Each 2x4" was bolted to the existing steel. A 5/8" sheathing of 4x8' plywood was then installed.
Phase #3. With a viable underlayment in place, Blackhawk Roofing completed the installation of a single-ply EPDM roof for the U.S. Post Office. We attached 1 1/2" ISO board over the sheathing, with RMS strips attached around entire perimeter. Using a commercial adhesive, we then glued commercial rubber (EPDM) to the ISO board. We also terminated the roof with bar and concrete plugs around entire exterior.
