What Is The Difference Between A Certainteed Diamond Deck And A Roof Runner?

Diamond Deck is a premium, heavy duty synthetic underlayment designed for maximum performance, while Roof Runner is a standard, cost-effective synthetic option. The choice depends on roof type/pitch, budget, and performance needs.

The main differences between CertainTeed’s Diamond Deck and Roof Runner synthetic underlayments are:

Weight/Thickness

Diamond Deck has a higher gram per square meter (GSM) rating of 185 GSM, while Roof Runner is thinner at 110 GSM. The heavier Diamond Deck is more tear and puncture resistant.

Traction

Diamond Deck has a slip-resistant surface coating to provide better traction when walking on steep-sloped roofs during installation. Roof Runner does not have this coating.

Flexibility

Roof Runner is more flexible and easier to work with than the stiffer Diamond Deck product.

Cost

Diamond Deck is a premium product that costs more than the standard Roof Runner. Upgrading to Diamond Deck could add $600 or more to project costs.

A Certainteed Diamond Deck Vs. A Roof Runner

Roof Runner is the most commonly used felt and is an excellent product. Diamond Deck has a slip-resistant feature that we would employ on a steeper-pitched roof. Both are fantastic products.

Diamond Deck:

  • Higher performance and more durable synthetic underlayment
  • Designed for steep-slope roofs and high traffic areas
  • Thicker (10 squares per roll) and heavier weight (185gsm)
  • Excellent grip and dimensional stability
  • Higher cost

Roof Runner:

  • Standard synthetic underlayment
  • Suitable for low to steep slope roofs
  • Lighter weight (110gsm)
  • Good UV resistance and water protection
  • More affordable option

 

What Is A Gypsum Roof Deck?

Gypsum Concrete Roof Decking is manufactured from calcined gypsum and wood chips or shavings. It is typically poured to a thickness of 2″ and weighs around 17.5 pounds per square foot.

Gypsum board and concrete decking are lightweight materials that can span huge areas, reducing the use of wood and steel. Gypsum boards for roof decks are attached with screws, nails, staples, or welded clips.

Concrete roof decking is protected from fire and water with a bitumen coating, which gives it a longer life span. It can also be painted, though the paint will eventually wear off.

Gypsum concrete roof decking expands and contracts less than wood and is strong enough to support the weight of accessories like vent fans and plumbing fixtures even when it is not secured to the core trusses.

Its major advantage is that it does not absorb water easily; water does not damage gypsum boards when in place.

They are designed to support interior walls as well as roofs. Where wood is required, you should go for pine boards which are the safest and most durable.

What Is A Reinforced Concrete Roof Deck?

INSUL-DECK Roofs are structurally superior to typical wood-truss roofs due to reinforced concrete’s substantially higher strength.

They can be designed and constructed to resist exceptionally high winds as well as the impact of the majority of flying debris in hurricanes and tornadoes. It can be installed without a lead-based primer and will not crack or delaminate.

Can You Put A Roof Deck On An RV?

Rooftop decks are becoming increasingly popular among RVers and vanlifers, allowing you to optimize your outdoor living area while taking in the scenery. A porch roof was important to add to individuals who had expanded their van or bus.

How Do You Build A Shed Roof Over A Deck?

To build a shed roof over your deck, you will need to follow the steps below; 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. Attach the support posts to the deck frame with post-base connections, using lag bolts in case of steel or deck screws in case of wood.

If using a post-base connector, drive the post into place, then insert the connector over the post. Make sure that you drive the bolt or screw through both decks.

  1. Set Support Posts. To ensure adequate lateral support, install support posts to every other post on your deck as close to their ends as possible (the posts you are supporting will be either an “L” or “T” shape).

It is important to remember that even decks made from wood and metal require support at either end from the structure on which they rest.

This is important to ensure that the shed roof frame you are creating will be strong enough to support and endure the structural loads.

  1. Temporary Bracing. Once you have set all your posts, resilient temporary bracing can be installed to help enhance the roof’s stability by supporting it at its mid-point or where braces are needed on a steel deck.

These braces should not extend beyond the outermost edge of your columns, as this can weaken and lead to severe damage in high winds.

  1. Install the Header Beam. The mid-support plate will mark the position of the header. The centerline of the column needs to be 1/4″ from the building’s edge.
  2. Installing the Header Next to the House. Then install the header next to your house by driving through the deck frame with a 12″ or larger screwdriver or hammer.
  3. Install the Ledger Board. Next, install the ledger evenly across these screws at a 45-degree.

  1. The Rafter Pitch Angle: The roof’s pitch adds the slope to a roof. When building a shed roof, you will want this to be a gentle slope at around 15 to 20 degrees.
  2. Layout your Rafters. You will want to layout your rafters using the diagram above, which can be amended to suit your needs.
  3. The Rafter Pitch Angle: Drill 2 holes (3/8″ or 1/2″) into each of your beams closest to the top and bottom of their surface on both sides with a drill and a 3/8″ drill bit:

What Can I Use To Stop Leaks On A Boat On A Roof?

There are a few options that you might consider for stopping leaks. You can use rigid fiberglass insulation boards (the ones with fiberglass lined fiberglass or aspen furring strips) covered with either spot-welded steel plate panels or by installing steel plate and gutter mesh.

The first option is pretty straightforward. You need to place the panels snugly against the existing roof structure, ensuring they are in line with each other.
