Although skylights may be placed in any type of roof, there are some special considerations that must be observed when installing them in metal roofs. Here are a few things Essex County roofers would like homeowners to know about skylight installation in metal roofs.

One of the most important considerations should be mounting technique. Skylights installed in metal roofs should be curb mounted rather than being installed flush with the roof. This means that a "box" or "curb" is created around the opening with 2x4 pieces of lumber. This provides a place for the skylight to sit on, allowing it to protrude slightly from the roof's surface. When flashing is installed around this curb, it provides a watertight seal than would be possible if the skylight were flush mounted.

Not any skylight can be installed on a metal roof. Homeowners should be sure that the skylight they purchase is designed for placement on metal roofs. This is especially important when installing a skylight on a corrugated metal roof.

The proper placement of a skylight is very important. On a corrugated metal roof, the preferred location is just below the lap.

It should never be installed across seams, as this could result in leaks around the skylight.

Skylights on metal roofs should never be installed above unfinished attics. Placing them above attics could result in air leaks, both in the attic and in the living areas below it. This in turn can result in condensation buildup inside the attic, leading to the development of mold and mildew.

Sealing the area around the skylight is extremely important. Before the curb for the skylight is built, a thin layer of roofing silicone should be placed around the opening, extending at least one inch wide all the way around it. Once the skylight is in place, additional roofing sealant may be needed prior to flashing installation.

It's important to note that skylights could require replacement long before a metal roof does. Most skylights have a lifespan of around 10 years, while metal roofs can last as long as 50 or 60 years. Any time a metal roof is replaced, skylights that are nearing the end of their lifespan should be replaced as well.

Skylights can easily be installed in metal roofs whenever these things are taken into consideration. Properly installing a skylight in a metal roof is essential if homeowners are to prevent leaks, ice dams and condensation, all of which could cause considerable damage to their home.
