Can't you eliminate the algae by cutting down any trees shading the roof?

I don't have the issue but I see many houses with it no matter the environment. Wouldn't it be better to let the air cool the roof...
Yes sunlight cures algae. I got some three tab 50 mph architectural shingles in 2011. Had to ask for the copper. I would use the zinc strips myself. I still get algae if I don't keep the branches at least 8 ft away.
Roof asphalt on the garage is 50 years old, no leaks.
I guess they did make it better decades ago.
Like yours, next week my 21-year-old NC roof is being redone with Certainteed Landmark Pro shingles. I'm having the contractor use materials and techniques that qualify it as a "Fortified" roof.

This is my roof from 1999. Had a shower so that's the darkness. No leaks and never any shingle loss.
We got hit last year with tons of big hail. I have about 50% granule loss.
When I go to sell it soon I'll put another roof on.
They were CertainTeed too.

IMO, here in the Midwest to get 8-10 years out of a roof is good. We get significant hail around here. We've put 2 roofs on in my 15 years of ownership.
Just my $0.02

I was reading about fortified roofs. They use nails with rings to make sure plywood will never be ripped off. Then seal the plywood with tape on all seams so it's pretty waterproof even if shingles get ripped off. Then I think ice & snow over entire roof. Then shingles.
I would ask about SBS roofs.
So the hail rips off the granules and it's downhill from there. Does insurance cover the cost of the roof?
Those GAF Timberline are on all my replaced roofs. Weathered wood color goes with everything.
They use ice and snow in the valleys plus Certainteed synthetic underlayment throughout, the nails are stainless steel and spaced closer together and they use better quality drip edging for the "fortified" installation. Then my homeowners insurance company allegedly will reduce my premium, which is about $4,500 a year. I considered a steel roof but opted for this instead.
So I need to go with GAF since that is what the roofer predominantly uses and is certified. You get a better warranty if the roofer is GAF certified.
If looks like in Delaware (with little hail potential) no one uses IR or SBS manufactured shingles. The roofing supply company told me they can get them but don't carry them. And the GAF SBS shingles are roughly double the cost. Not sure why SBS are so expensive as I think all they do is to toss a few tires (rubber) in the asphalt mix.
I will bet as time goes on more and more will be SBS. All Malarkey are SBS or rubberized asphalt.

There is/was a shingle manufacturing plant in Delaware off of Governor Printz Blvd...IKO I believe.
Many roofers in my area (Cleveland) are steering away from GAF Timberline because of premature granule loss. I know several people who had issues with them.
GAF Timberline includes a few grades of shingles. Timberline HDZ and Timberline Ultra HDZ and Timberline AS II. And others. Do you know what grade? Was is just loss of granules in general or after hale?
