1. Weather

  • If the roofing is being replaced during cold weather, additional steps are necessary that require additional time.

  • Cold weather can affect how the asphalt shingles stick and seal. According to Certainteeds shingle installation bulletin, Extra care should be taken when handling and/or installing asphalt shingles when the air and surface temperatures are at or below 40 degrees Fahrenheit.
  • Snow covered, wet or icy roofs make for hazardous and unsafe working conditions for our roofing crews. You can read tips from Certainteed here: Safety Tips from Certainteed

    Prevent Further Damage!

    Most homeowners policies require you to cover the damaged roof immediately.

    Did you know?Claims for secondary damage are usually denied when the necessary steps have not been taken to protect the roof.

    Heres a common and unfortunate scenario:

    Storm 1 blows a bunch of shingles off a roof.

    Storm 2, a week later, brings wind-driven rain that gets into the unprotected home and destroys everything it touches ceilings, walls, flooring, electronics and more. This is why many homes must be gutted or demolished after hurricanes.

    Bad storms damage hundreds or thousands of homes in their path. This makes it impossible for roofers to make quick repairs.

    Instead, your roofing company will get the damaged areas tarped and secured to protect your home and your wallet. Once this is done, the roof should be OK until repairs can be made.

    Other Common Roofing Problems

    Leaks can also occur around other areas of the roofs flashing, such as the counter flashing surrounding the chimney, or the step flashing at the base of a dormer or adjacent wall. If the counter flashing around your chimney is leaking, use roof sealant to repair cracks and glue individual pieces back down.

    If you find a leak in the step flashing along a dormer, a sidewall, or around a skylight, there are two options. The first is to replace the flashing, which means you have to strip away the shingles and siding in that area, then reverse the process by installing new flashing and siding.

    The second option is to repair the damaged flashing with a judicious application of roof sealant. The trick here is to keep the sealants surface relatively smoothbig beads or lumps of sealant can actually divert water, preventing it from draining properly. Nails used to secure flashing should not be exposed if they are exposed, apply sealant to their heads. In some cases, repair is only a stopgap until the flashing can be replaced with the rest of the roof.
