What Can I Use Instead Of Felt For The Shed Roof?
Instead of felt, EPDM membranes can be used for the shed roof. It comes in rolls of varying sizes and can be used to cover flat or curved surfaces. EPDM membranes are made from rubber and do not sag, crack or rot.
The natural color is black, but it is also available in different colors. You may wrap the roof with a membrane instead of felting because you want a seamless finish.
Avoid laying your shed’s roof directly on the ground if you want to prevent moisture from accumulating underneath it.
Water buildup under your shed will cause the wood to rot and affect its overall stability – eventually leading to structural damage that may cost more than fixing the damage at once.
How Do You Build A Shed Roof Over My Existing Deck?
To build a shed roof over your existing deck, the following steps will help you; Post Base Connectors, Set Support Posts, Temporary Bracing, Install the header beam, Installing the header next to the house, Install the ledger board, The rafter pitch angle, and Layout your rafters.
1. Post Base Connectors.
Install post-base connectors to connect the support posts to the deck structure. To establish a firm connection, ensure that the frame has adequate blocking. Do not attach the post base to the decking to reduce the chance of cracking.
2) Support Posts.
Set up the support posts at various locations within the framing pattern of your deck, with clearance for a two-inch gap between posts. The location depends on your shed’s size and how much soil you want to raise off the ground.
The idea is to get a few inches of clearance in case nails to loosen up or loosen during construction; this will allow water to drain out of the bottom of your shed instead of building up and causing rot.
3) Temporary Bracing.
If you’ve decided where your support posts go and have decided on a roof pitch angle, it’s time for temporary bracing to help hold things in place until construction begins in earnest.
The temporary bracing also helps keep things level during construction, which makes it easier to lay out framing and rafters.
4) Header Beam.
The header beam is a long, flat piece of wood that carries the entire weight of your shed’s roof load down to the support posts.
To install it, you might want to place a 2×6 or 2×8 right-angle brace or joist on each side of the post to help hold everything in place until you get your support beam.
5) Ledger Board.
The ledger board sits on top of your house structure and rests directly on column caps at every end connection point. These caps help people see and understand where a connection is located.
The ledger board is important for 4 reasons: It’s the point of contact between your shed and the ground so that moisture and debris don’t collect on it.
It provides a smooth surface upon which the rafter ends rest, so they aren’t banged up or dented. The ledger board is the primary support at each end of the building, helping keep all those heavy rafters in place.
6) Rafter Pitches.
The rafter pitch angle is the angle at which your roof boards are set (or how steeply your roof slopes). For sheds, the most common angle is 4:12.
If you add a shed roof to your home, you can typically use the existing angles and simply change your old wood for new ones. Building an entirely new shed means you have many more options for rafter pitches.
7) Layout Your Rafters.
Once you’ve decided on a rafter pitch, use a framing square to mark the length of every rafter from your support posts. To get your exact measurements, add 2 inches at each end of the rafter boards so they overhang the supports.
Cutting them on the ground is much easier than trying to cut them on your roof, and you risk making mistakes that could be dangerous.
