What do you do about roof flashings?

Flashings are used wherever something intersects the roof. These are the most important areas of your roof. Various materials can be used to protect these areas: sheet metal (copper, galvanized steel, aluminum), Lead, ice and water shield, membranes, and sealants can be integrated at siding, chimneys, walls, gutter lines, skylights, pipes, and vents. If the existing flashing is in good shape they can sometimes be re-used. However, since flashing can be the most critical roof component we recommend new flashings if there is any concern about the existing.

For residential roofs, typically, one or two days (of course, if your roof is very large – or if substantial repairs are required – it could take a bit longer). The weather can also delay the process, but we will always ensure the roof is water tight from beginning to end.

Typically, the removal and replacement of gutters will allow the installation of ice and water shield onto fascia boards which would seal the outside edge from water infiltration in ice damming conditions. We can replace gutters with or without a new roof. We install copper, galvanized steel and aluminum gutters. Our roofing professionals will be able to determine this for you, and explain the benefits of replacing your roof and gutters together.

Sometimes we can, depending on your roof and what’s up there. Most re-roofs should be evaluated on a case by case basis. Generally speaking, tearing off existing materials, inspecting the decking (as well as the general integrity of your roof structure) and then installing your new roof will guarantee optimum long-term performance.

Ice and Water Shield is a protective underlayment that is put on over the wood deck prior to any shingles. Ice and Water Shield helps prevent water infiltration during ice damming situations. We typically install Ice and Water Shield along the eaves, around chimneys, skylights and in all valleys.

We’ll rake and sweep all debris from the roof and around the house (sidewalks, driveways, etc.). Then we’ll use nail magnets to find and pick up nails. We will perform a final inspection of your new roof and your grounds to assure your complete satisfaction

For a new skylight installation there’s no better time to have the work done than when you’re replacing the roof on your house. If you have skylights that leak or give you other problems, we will come out and diagnose the problem to the best of our ability. In this day and age skylights on shingle roofs have become much more common, and affordable. If you would like to add a skylight let our estimators know and we will provide you with a variety of options.

We are fully insured for both workers’ comp and general liability coverage. What this means to you is that you will never be responsible for any of these expenses. We will provide certificates of insurance upon request.

Does a Metal Roof Produce More Noise Than Other Roofing Types?

Not at all. A metal roof properly installed by a professional is typically fitted above the attic area, as the top of many layers that include insulation, a roof deck, and underlayment. This configuration ensures that metal roofs are just as quiet as other available roofing materials.

Absolutely. Compared to most other roofing materials, metal roofs offer enhanced safety during a lightning strike due to their non-combustible nature. Petersen’s metal roofing systems undergo UL testing for fire safety. Your rep can provide specific information on fire rating.

Yes. In regions prone to significant snowfall, metal roofing is highly favored. Its ability to swiftly shed snow not only preserves the roof’s structural integrity but also prevents the formation of ice dams at the eaves, which can lead to water backup and potential leaks into the home.

Actually, no. A metal roof is on average 50% lighter than a roof made of asphalt shingles and 75% lighter compared to those constructed from concrete tile, fiber cement shakes, and slate.

Flat TPO Roofing

Can You Install Flat Roofing?

Yes

Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polypropylene and ethylene-propylene rubber polymerized together. It is typically installed in a fully adhered or mechanically attached system, allowing the white membrane to remain exposed throughout the life of the roof.

Yes, TPO is the most popular roofing membrane for commercial buildings because it is cost-effective, energy-efficient, and installs well over large flat areas. It is also a great residential flat roofing membrane because of its durability, reflectivity, and longevity.

Typically, 20-30 years, depending on membrane thickness, quality of installation, and climate conditions. We have seen some roofs last over 30 years with proper installation.

Yes, white TPO membrane reflect sunlight, reducing cooling costs and improving energy efficiency.
