What does a “safe” roof look like?

The roof of a house can be inspected from the roof itself, as well as from the ground via roof access points such as chimneys or roof hatches. There are many different things to consider when inspecting a roof, and those include roofing materials, roof covering, roofing conditions, types of flashing used on the roof, condition of gutters and downspouts, water movement across the roof surface, etc.
The roof is one of the most overlooked parts of a building until there’s an issue with it. It will often go without attention until it starts leaking or breaking down for other reasons.
A roof inspection can be performed at any time, but roofing inspectors will often check an existing roof after a severe storm to make sure that damage hasn’t been done. It can also be a good idea to have roof inspections regularly scheduled, particularly if the roof is frequently used or if it’s in a damp location such as near a pool.
Most roof inspections should include an analysis of the roof structure to ensure that there are no issues such as rotting roof beams or other problems like rusting nails and screws in roof trusses. Finally, roof inspectors usually check the condition of the roof gutters and downspouts since there’s a relationship between roof drainage and roof maintenance. This is done by looking for roof leaks and torn gutter systems while also checking downspout installation and footing drains around the house. If any repairs need to be made they’ll make suggestions on how to fix them and provide estimates or quotations if they’re available.
These inspections are usually performed by roofers who will look for problems and either fix them or give advice on how to get them fixed. They’ll check roof covering including roof shingles, roof tiles and roof membranes and ensure there’s no damage or wear and tear visible. They’ll also inspect any flashing around chimneys and skylights for defects and damages, making sure everything is watertight so that no roof leaks can get through. know about this more here https://en.wikipedia.org/wiki/Roofing
