Your roof is more accurately described as a roofing system — integrated layers of building components and barrier materials that work together to shed water.

Aging decks can become eyesores. They may also be damaging your home because the transition where a deck attaches to an exterior wall is one of the building envelope's most vulnerable areas for water penetration.

Replacing your roof? Replace your aging skylights at the same time. It makes no sense to install a new roof around skylights that are nearing the end of their useful lives and are increasingly likely to leak. Instead, use your roof replacement project as an opportunity to upgrade to new, energy-efficient skylights that are flashed and sealed properly with your new roofs.


Many first-generation condominium buildings use pine trim, which is notorious for high-maintenance costs and premature failure. For the greatest long-term value, replace pine trim with long-life, low-maintenance PVC trim. Unlike pine trim, PVC trim does not absorb moisture, a primary cause of rotting and paint failure.

Above-Roof Siding

Condominium roofing systems are particularly vulnerable to water penetration where the roof meets above-roof transition walls. Replacing roofing and shingles at the same time allows these transitions to be flashed properly with waterproof underlayment, a standard component of today’s roofing and siding systems not used on most first generation condominium buildings.


Planning a siding replacement project? For the highest quality weatherproofing, upgrade to more energy-efficient entry and sliding doors at the same time. This is especially true for sliding doors that open to decks, where door, wall, and deck transitions must be flashed properly to prevent water penetration.
