Since there's a bunch of knowledgeable solar guys in here right now, and it kind of fits the topic, I think it might be appropriate to ask this question here.The solar panel installations that I've seen on Youtube, TV, etc that are retrofit - i.e. not put on when they're replacing a roof, which I've never seen - always shows them drilling bracket mounting holes straight through the asphalt shingles.

Removing the asphalt siding has been finished up and wrapping up installing the house wrap. 

Glass block windows are good.Looks like there is central air.Someone may have to deal with sidewalk out front. concrete is missing in front of the treeDriveway needs a look, looks like the asphalt need repaired/replaced.Roof needs a closer look.

Last summer we had 75' under asphalt 4' excavated and replaced about 30' of old 6" concrete sewer line with 6" green ABS for $5028 all-in, including 8% sales tax.

The laundry room was completely renovated3) New Community room was remodeled and installed4) New Gym room was remodeled/installed Parking Lot $18,583 1) Patch and repair 4K sqft of Asphalt all around the property Playground $30,131 1) New Playground at Villa and New safety area for old playground Plumbing improvements $44,704 1) New PRV (Pressure Reducing Valve) for main line2) New Water Softener for the main line3) Major plumbing section replacements as needed.

The land and asphalt all add up by adding 10 ft.

DO NOT USE A PRESSURE WASHER . the oil soaked into the asphalt , if you pressure wash it you will blow the oil soaked asphalt away , making a hole .Call a professional seal coat company . one that uses coal tar , or asphalt emulsion .

The exception had original cedar shakes and they just replaced them with architectural grade asphalt.

I just hate doing asphalt roofs.

I'd call a few roofers in the area off of Craigslist and ask them, in general, what they'd charge per square for a basic, asphalt shingle roof.
