Sealing Roof Skylights

Next put new weather stripping on the curb of the skylight window.

Sealing roof skylights.

Take a moment to seal any cracks you find on the cover with the clear silicon caulk. Now apply more cement to the edges of the shingles which are intersecting with the next shingles in place. Make sure that the space between the edges is completely sealed with the roof cement. With a scraper slowly remove the weather stripping around the skylight cover and the curb.

Use a trowel to smooth the cement over the entire area. You should spread the cement at a thickness of about 1 4 inch. To seal these types of leaks in the flashing area you will need to raise the shingles near the skylight window. Identify the areas where the flashing meets the roof and spread roofing cement around the entire window at these sections.

Now place the cement at the edges of the shingles which are joining with the skylight. Gently point the tip of the caulking gun under.
