roof

Hello everyone,

The house I bought has tar and stone on the roof. Supposedly the previous owner said he was going for a "California Look." Does anyone know how to replace this roof. Obviously the stone has to be scraped, do you think new boards over the existing tar and then a timberline? help

A good rule of thumb is to tear it all off. If you do not, you will not know if you have any bad subroofing boards. If you do not, you will also have a new roof which will not lay flat. Good Luck

Roofdog: I have no idea what it is. Must be a New Jersey thing.

Timberline is a brand of asphalt shingles. It's like the asphalt shingle Xerox in the area.

Timberline is a laminated shingle made by GAF.

What is the roof slope? If I remember correctly, the maximum slope for an asphalt & gravel roof is something like 3:12.

If you want to go this low with a shingle, there are special things you need to do. Someone correct me if I'm wrong, but isn't 3:12 the minimum slope with shingles?

i wouldn`t go over the roof with boards and shingles,tear it off and start from there,if you are going to stay with the flat roof...there are many different flat roof materials,rubber,burn-on,pvc,hot tar,also the minimum pitch for shingles is a 4/12 but you would need ice sheild on the hole roof.

Officially, the lowest slope warrantied for shingles is 2:12.
However, any shingles applied to slopes 2:12 to 4:12 will require either 2 layers of felt or a self adhering modified membrane (ice and water shield). 4:12 slopes and above can be applied normally.

In my opinion, anything less than 4:12 should use a "flat roof material" as mentioned by Roofdog. There are many types, mainly hot asphalt, torch products, or cold adhesive.

On this roof, you could spud the gravel off, but you would need to re-deck with plywood anyway to get a smooth surface.

I agree with Jack the Contractor's advice. When I have a choice, I would always tear it off and start anew.

Good luck.
