Your roof can sustain damage in a number of ways. The weather, sun exposure, and animals take a toll over the years. Even your gutters can cause damage if they allow water to back up against the roof and cause water damage. When this happens, the soffit, fascia board, and shingles could be damaged. Here's a look at how this happens and the repairs that might be needed.
How Clogged Gutters Can Cause Water Damage
When your gutters are full of leaves, or if the slope is altered so water doesn't drain, then rain can flow against the underside of the roof or go under the last row of shingles. If this goes on for a long time, the soffit and fascia may start to rot. When the wood rots, bugs might move in and escalate the damage. When the wood gets weak, animals can take advantage and chew through it to get inside the attic. Your roof will look ugly with rotting boards and curling shingles, but even worse, the damage can allow water and animals to get in your attic and cause more damage. These problems can often be prevented by making sure your gutters are kept clean and draining properly.
How Roof Repairs Might Be Done
Unless the fascia boards are all old and rotting because of age, damage like this is probably contained to one area where the gutters weren't working. The edge of the roof has a final row of gutters and a metal drip edge that is above a board that's called the fascia board. The soffit is the underside that has mesh openings so the roof has ventilation. The roofer may need to cut out the damaged soffit and fascia board after removing the gutters from the area. The gutters hook onto the fascia board, so they'll need to be out of the way. The rotted wood is replaced with new materials. Next, the roofer repairs the shingles if they need it. The bottom row of shingles might be curled or loose, and these need to be held in place firmly to prevent lifting by the wind. Replacing the shingles is a matter of pulling nails out of the old ones, removing the shingles, and then putting new shingles in their place.
One thing you may want to consider is future animal damage. If a raccoon or rats were using the rotted area as access to your attic, they might try to chew their way back inside once the roof repair is done. Watch for this problem so you can take steps to protect the roof before the animals can damage it. If you see signs of animal activity, then calling in a pest control expert before damage is done could prevent the need for repeat roof repairs.
