How Much Does Each Part of Skylight installation Cost?

The cost to install skylights in Allentown ranges from $980 to $3,910, with most homeowners paying around $2,150. Your actual cost depends on several factors specific to your home and the Allentown-Bethlehem market.

🔌
Skylight Type (Fixed, Vented, Tubular)

Fixed skylights are cheapest ($200–$600), vented models that open for airflow cost $400–$1,200, and tubular skylights for small spaces cost $200–$500.

Roof Pitch

Skylights on low-pitch roofs need extra flashing care to prevent water pooling. Very steep roofs require more complex installation and safety measures.

📏
Flashing Kit

A proper step-and-counter flashing kit is critical for waterproofing — quality kits from the skylight manufacturer cost $50–$150 and are essential for a leak-free install.

🔧
Interior Shaft Construction

If the roof and ceiling aren't the same plane, a light shaft must be framed and drywalled to connect them, adding $500–$1,500 per skylight.

🏗️
Number Of Skylights

Multiple skylights reduce per-unit installation cost since the roofer is already set up, but each still requires its own shaft, flashing, and finishing.

Using a certified installer and the manufacturer's flashing kit virtually eliminates leak risk. Quality skylights carry 10–20 year warranties.
