Today, acrylic or polycarbonate dome skylights come in several sizes. However, the traditional is a square to rectangular shape with a height of about 5 inches. They can be 12" to 36" in width and 1/8" thick.
These domes can be mounted on wooden curbs [2x2" to 2x6"] with shrouds or thin metal flashes around the roof tiles to prevent leakage of rain around them. These domes can also be surface mounted directly on the wood directly below the tar paper and shingles.
In the latter case, the shingles around the dome itself are laid directly on their flat outer flanges, similar to the way in which shingles are typically laid on flat metal such as roof vents, grate, sewer vents, and the like. This installation minimizes the height of the dome.

. Either way, or regardless of how the dome is mounted, even if they have a plastic shield inside, they can create unwanted condensation and similar leaks. These domes are also easily broken by large hail, fallen branches, earthquakes or careless roof workers. When these events occur, in addition to the formation of moisture, the skylight will also leak rain.
solutionfrom
. A 5-1 / 2 inch high-hard transparent cover similar to a light box was built and mounted on the dome on the roof. This cover is like a storm window, subject to temperature changes and the formation of most condensation. For this article, a 20" square dome [in the 18" square dome itself includes a 1" flange on each side, 5" high, and a direct surface mount on the roof panel will serve as an example of coverage. Like the box-like storm cover, a similar cover can be scaled to other dome sizes.
Materials and tools from
[Total cost of parts: $50-90, depending on the availability of the acrylic plate].
- A 2x6x96 "pressure processing board [$5]
- A piece of 22x22 "0.22" thick acrylic plexiglass [$25-$60, depending on the cut size at the exit]. If it is necessary to cut the sheet from a larger sheet, leave an unpeeled protective film on both sides of the sheet until the sawing is completed. Use a sharp, fine-tooth saw blade. Otherwise, let the outlet cut it to fit your size.
- Twelve #12x3" Philips Screws
- 20 to 30 - #8x1" Philips drywall nails [wide head]
- A small tube of transparent silicone glue sealant [$4]
- Two silicone window/door caulking colors similar to roof tiles [$8]
- Four vertical flat 2-1 / 2" L-shaped brackets [$5]
- Eight #10x1" wood screws [for attaching the L-bracket to the cover frame]
- Eight #10x1-1 / 2 to 2" wood screws [for connecting the frame's L-bracket to the roof via a blister]
- One quart oil-based waterproof coating, similar in color to roof tiles [$4]
- Tools: electric circular saw, electric drill, drill bit, Phillips screwdriver, caulking gun, putty knife, rat tail, brush
Cover constructionfrom
.
1. Cut the 2x6" plate into four square pieces: two 22" long plates and two 19" long plates.
2. Use a silicone window/door waterproof sealant and 3" screw seal/fix four corners to assemble a 22" square box frame.
3. At the bottom of the bottom, use this file to make at least three half-moon trees for drainage.
4. Paint the interior and exterior of the wood frame. Let us do it.
5. Rinse the acrylic plexiglass onto the frame.
6. Mark the plexiglass where the screw holes will reach, about 5 inches around the top of the frame.
7. At each mark, drill a hole in the plexiglass [only] to make it wider than the drywall screw.
8. Then, by using a narrow drill bit, drill through the hole in the plexiglass hole into the hole of the dead end of the wooden frame.
9. Remove the plexiglass from the frame and notice how it fits on the frame.
10. Brush off any plastic or wood chips on the frame and plexiglass.
11. Using a silicone sealant, add a narrow bead longitudinally around each hole in the frame.
12. Carefully replace the plexiglass at the top of the frame and align it with the original drill hole accordingly.
13. Install the screws to a medium seal to avoid rupturing the plexiglass. The joint compound will flatten and unfold between the plexiglass and the frame to seal it.
14. Use a 1 inch wood screw to add at least one flat L-shaped bracket to each side of the frame.
15. Draw parentheses.
Cover installation from
[simple way].
1. When using safety precautions, move the finished cover to the roof, assuming the roof is low-pitched and can walk safely.
2. Place it above the dome skylight, square to square.
3. Using a 1-1 / 2 to 2 "wood screw, connect the dome to the roof via a blister based on the thickness of the herpes zoster.
4. Seal the top and sides of the lid with a silicone window/door fillet. Seal the bracket and screws in the same way. Keep the bottom of the lower end unsealed for drainage. This is a storm window.
5. If necessary, repair the frame and bracket with paint.
By installing a cover on the roof panel, the wood under the shingles also prevents any moisture damage. This placement also lifts the lid onto the dome to get enough space.
This cover will assume that almost all condensation forms, otherwise it will occur inside the dome, and none will enter the house through the dome or under the shingles. It also protects the dome from hail, fallen branches and other damage. To learn more about sunroof types and their maintenance, see these sites.
