Warning signs that a roof needs to be repaired or replaced:
Leaking roofs, poor drainage, and clogged gutters and downspouts can lead to significant water damage inside your home. To help determine if you need a new roof, your roofing contractor will conduct an outside and inside roof inspection.
Inspecting a roof from outside is very simple. All that is needed is a pair of binoculars and a viewing point that is unobstructed by other buildings or trees. Following is a checklist of problem signs you can look for during an outside roof inspection
Matchless Roofing has listed below a series of roof problems that every homeowner and roofing specialists should look for to determine whether a roof need repairs or replacement.
Residential Outdoor Inspection:
- Caused by leaks in roof
- Check attic or crawlspace for leaks in deck
- Check chimney and vents for cracks in flashing
- Check rafters for leaks that travel away from original source
- Check roof for damaged shingles
- Caused by Improper installation on a new roof and by expansion and contraction will cause fasteners to become loose and the bottom-flashing
- Drying and cracking on an old roof
- Dented by improper nailing
- Settling of the Structure
3Damaged Flashing Missing and/or Broken Shingles
- Caused by improper fastening
- Exposure to high winds
- Can usually be replaced individually
4Curling of Shingles
- Caused by improperly felt, or movement of the deck
5Curling of Shingles
- Caused by water absorption
(in wood or fiber-reinforced shake)
- Caused by moisture in the shingle
- Occurs when ventilation is inadequate
- Caused by growth of airborne algae
- Occurs most often in warm, humid climates such as the southeast United States
8Missing Granules and Bare Spots
- Normally a certain number of granules will be loose, especially after application
- On aging shingles, this indicates the need for replacement
- Caused by absorption of moisture by the mat
- Common problem with organic-based shingles
10High Energy Bills
- While this one cannot honestly be 100% attributed to your roof, a faulty roof certainly won't be making it any better. Like with the problem of blistering paint, your roof issues can cause problems with proper air circulation and ventilation, trapping in hot air which makes your AC unit run longer and at lower temperatures.

Residential Indoor Roof Inspection
Following is a checklist of problems/signs you can look for during an indoor roof inspection.
- Sagging decking between the rafters. If the decking is sagging or deteriorating, the decking will also require replacement when a new roof is installed.
- Outside light that can be seen through the roof. This may be common (and not a problem) on shake roofs, since the wooden shakes will swell during the wet months, effectively preventing any leaks.
- Signs of leaking in the attic (dark spots in the wood, especially around vents, chimneys, and other holes to the roof).
- Test dark spots in the wood to decide if they are old or current problems. If the spot is still wet, or if it is soft (test with a screwdriver), the spot is a current problem. If the spot is dry and hard, it is most likely an old problem that has been fixed.
- Signs of water damage or leaking (usually in the form of water stains, or sagging ceilings)--this could be due to an active leak in the roof or to condensation caused by poor roof ventilation.
