The covering
Granule loss, mat condition, lifted tabs, nail pops, and the layer count taken at an edge or a vent rather than estimated.

Before a sale, after a storm, or simply because the house is at the age where somebody ought to look. Free, and you keep the findings.
A great many inspections end with nothing needing doing for several years, which is a perfectly useful answer to have in writing. The ones that do not end that way are far cheaper to deal with found early than found through a bedroom ceiling.
Granule loss, mat condition, lifted tabs, nail pops, and the layer count taken at an edge or a vent rather than estimated.
Flashings at the chimney and sidewalls, valleys, pipe boots and vents. This is where most roofs actually fail, long before the field does.
Where there is attic access, the deck read from below for staining, daylight and anything that has been wet long enough to go soft.
Gutter falls, downspout discharge and where the water ends up, because a roof that drains into its own fascia is a roof with a short future.
A plain account of the condition, photographs of anything noted, and a rough view on remaining life. Written so that it still makes sense in two years, and specific enough to hold another opinion up against.
A full tear-off planned around the frontage first, so four tons of old covering leaves the street without closing it.

Read the page →Tracing a leak back to where the water actually enters, which is rarely above the stain.
Read the page →A documented look after a blow, with the damage photographed in a form that is actually usable.
Read the page →Walls and trim fitted by the people who did the covering above them, which is how the flashing between the two ends up right.
Read the page →The drainage sized and hung for the roof above it, and discharged far enough from the house to matter.
