No. Not really. Many of these can be installed UNDER shingles. So yeah, some shingles must be removed, but after the anchor installation the shingles are replaced. Permanent anchor.

I suggest a qualified roofer.

Super Anchor #2816 RS-20 20-gauge stainless steel universal permanent rooftop anchor with fastener kit & installation instructions. Complies with OSHA 1926:502(d)15. Quantity discounts available - please call for current price. Price/Kit. RS-20 is an anchorage device for high and low profile roof tiles that does not require a flashing system and can be retro-fitted onto existing roofing. Uses two _layer_s of 20 gauge stainless steel, the anchor attaches at the ridge, the hip or in the field and is easily conformed to the pan or barrel section of the tile. By penetrating under an overlapping course the need for a flashing system is eliminated. Attachment to the framing is easily accomplished using supplied 10ga stainless steel spiral shank nails. A minimum of two anchors are required to provide fall protection for both sides of the roof. (Install about one per side per 1000 sq.ft. area). The RS-20 is also compatible with asphalt shingles, wood shake, _meta_l, slate, copper and "simulated tile" _meta_l roofs.

Are ya ready for the best part? From this company, the cost is 30 bucks! http://www.bestmaterials.com/detail.aspx?ID=14857

This one from MSA doesn't require the removal of shingles.

Dave,
Here's an article from a pro roofers site.

I can understand on some larger municipal buildings that a huge tie in loop could be installed at the top of the roof that would last for centuries. But most of these "Permanent" tie ins for roof installation do not look like they would last forever.

If I was having a high quality roof installed, one that would consider the installation of permanent anchors, I would not expect anyone to have to be back up on that roof for quite some time. Maybe a paint job or something in 10 years, We never even have to paint our old standing seam more than every 5-10.

Would you want to just hop up on someones roof as a professional, and trust a tie in to some loop that someone else installed almost a decade ago??? I'll stick to our usual system of ropes and ladders.

Independent professional or employee or mere homeowner? I think any tie-in would be better than none, since you can look at it and then decide if you want to use it or not.
