Climate and energy performance in Lake Ronkonkoma
Suffolk County sees about 46.0 inches of precipitation and 31.8 inches of snow in a normal year.
Weather at that level is one more reason the flashing and sill pan under a Lake Ronkonkoma window matter as much as the glass sitting in it.
So ask any Lake Ronkonkoma contractor how they handle both, not just which brand they carry.

- What flashing and sill pan will you use, and in what order do you install them?
- If my home was built before 1978, is your crew lead-safe certified for this job?
- What's the completion date in writing, and what happens if the schedule slips?
