Snow Shovels by Briggs & Stratton

Think I'd prefer shovelling by hand to warm up, but these snow shovels by Briggs & Stratton could be useful!

Lidl Tools from the Centre Aisle - Air Wedges

Picked up this set of air wedges in Lidl . They're like a mini version of what firemen use. Handy for lifting and positioning stuff and pushing things apart.

Valves for Shutting Off Water in the Home

Just a reminder folks to identify where all your gate valves are for shutting off water in an emergency. Tie a label around them or write the function on the wall behind with a thick marker. Valves can and do seize, so it's good to exercise them at least once a year. You don't want to be running around like a headless chicken when there's a water leak.

Building a New Garden Shed - Cladding the Roof

Once the roof was covered with underlay, it was sheeted with painted, square profile, galvanised steel cladding. This is really supposed to be fixed to laths nailed or screwed to the roof/walls, however I fixed it directly.

Building a New Garden Shed - Adding Underlay to the Roof

I sourced a permeable membrane from Screwfix.com to act as an underlay under the steel cladding. This catches any condensation drips from under the sheets, carrying it to gutters. Also its underside has a rough woven texture, so water vapour in air landing on the underlay doesn't condense. Without this, on a frosty day, the underside of un-insulated steel cladding can get covered with condensation which ends up dripping over everything.

Building a New Garden Shed - Bracing the End Walls

Strong winds always blow from the south west and these would hit the front walls. I braced both short end walls with a "V" layout of 2 x 4s meeting at the ground and bolted to the corners of the walls.

Building a New Garden Shed - Adding the Fascias

I decided to use 2 x 7s for the fascias. Stronger, more chunky and less likely to warp than 1" boards. Before nailing fascias onto the ends of the rafters, I treated the latter with creosote substitute as a preservative. The fascias were nailed with galvanised 4" nails. Blocking (nogging) was used on the end walls for spacing the fascia. Quick release clamps held the boards in place until they were nailed.

Building a New Garden Shed - Adding the Roof.

Once the top plates were in place, it was time to build the roof. On advice from carpenters on  a building forum, I decided to use 2 x 7s for rafters. Snow load can potentially amount to tons of weight on a roof. 

Birdsmouths or notches had to be cut out of the ends of the rafters to allow them to rest on the top plates.

Rafters nailed into Place.

Building a New Garden Shed - Four Walls in Place

Four walls erected and ready for top plates. Notice the 1 x 2 diagonal braces. These were added to keep everything square. Should have cut the overhanging apple tree first. Removal was a bit awkward to avoid demolishing the walls!

Building a New Garden Shed - Erecting a Second Wall

All work was done single handedly and while walls were not excessively heavy, some thought had to be put into rising them into place. Quick release clamps placed at strategic locations at arms reach allowed me to clamp on lengths of 2 x 4s to act as stays to keep the walls in place. Once this was done, the stays could be nailed into place to make them more secure. 

Building a New Garden Shed - Erecting the First Wall

Walls were constructed from 2 x 4s. Treated 2 x 4s were used for the bottom plates in contact with the concrete. I nailed on 4" damp proof membrane with galvanized slab nails to give the timber additional protection from rising damp.

Building a New Garden Shed - Laying Concrete

Concrete was laid in six sections. I used 2 x 4s to frame the perimeter of the floor. 1200 gauge polythene sheeting was used under the concrete as a moisture barrier. This makes for a really dry shed. If you don't use a damp proof barrier, moisture rises rises through concrete and on a frosty day it can condense on everything.
