The National Roofing Contractors Association (NRCA) recommends
you do a roof inspection at least two times a year — spring and fall.
The best place to begin is inside your house –
– grab a flashlight and go to the attic.
Here are four things to look for on the inside:
- 1) Places where the roof deck is sagging
- 2) Signs of water damage or leaking
- 3) Dark spots and trails
- 4) Outside light showing through the roof.
When you take a look at the exterior of the roof, pay attention to such things as damaged flashing, missing shingles, curling, blistering, buckling, rotting and algae growth (which occurs most often in humid climates and appears as dark or greenish stains).
these tips are what to check on the outside:
loose material or wear around chimneys, vents, pipes
Watch out for an excessive amount of large grains of sand in the gutters — this is a sign of advanced wear.
Examine the drainage, and make sure gutters and downspouts are securely attached.
