[RE-wrenches] Protecting Asphalt Shingled Roofs

[Chris Worcester]

The hose is our best friend, next are foam pads like a twin mattress size, these grip well. We’ve used cardboard over the ridge to protect it from ropes if our lifelines go over it. On the steeper pitches we use walk boards made from ripping 5/8” or ¾” plywood into 12” x 8’ strips and nailing/screwing a 2x6 or 2x10 to one edge, depending on the pitch. Then we drill (3) 1” holes to run webbing through and tie them off to our standoffs. These work well, we’ve also laid 2x4’s above the lower row of standoffs allowing us to walk on them.

Hi James,

 

Great topic! Minimizing roof wear and tear during installation is a big deal. We have Yellow Spaghetti mat (http://www.bestmaterials.com/PDF_Files/yellow-spaghetti-datasheet.pdf) and carpet scraps. Each has pros and cons. Spaghetti mat is durable and we use it over and over. It does get slippery when wet and doesn’t have good enough grip over ~ 26-30 degree pitched roofs. Carpet actually performs better when wet but it gets heavy and messy. We can also use carpet on steeper roofs where we actually tie it off to our anchors by making a hole in the top of the carpet piece and tying a rope to it. 

 

It takes a lot of perseverance to get crews to consistently protect the roof to the level that is required to minimize damage. It has to be part of every installation plan just like fall protection.

 

On hot days we try to get on the roof as early as possible and off the roof by the time the roof gets warm and soft. One of my colleagues mentioned that they would spray a roof down with a garden hose to cool it off on hot days, I  haven’t personally tried that.

We have used carpet scraps, they stick well and cheap, we get them from a local installer

Aloha Team Wrenches,

 

How are we best protecting asphalt shingled roofs during the install?

 

Does anybody use "yellow spaghetti mats" up on pitched roofs with any success?

 

Mahalo in advance,
