Can tree pitch eat holes in metal roofing?	Guest User 9/27/2017	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22462/find/
Tree pitch? Do you mean sap? It can certainly, in the right conditions, damage the finish but I haven't seen it eat through.	Eric Novotny An informed customer is the Best Customer! 9/27/2017	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22463/find/
Is algae a problem on metal shake shingles	Eli Meister 8/8/2018	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/23466/find/
Algae can grow on anything if the conditions are favorable for it. In the comparison, algae will be much, much less likely to grow on a non-porous substrate like metal as compared to something like shingles or wood shakes.
