To prevent Dry Rot from invading your house, a good repair strategy is nessessary in order to eliminate the environments that it.
Termites are attracted to weak or damaged wood. Constant or prolonged periods of dampness is the enemy of wood on exterior structures. If rain is allowed to permeate through the wood and keep it perpetually wet, it will weaken and cause Dry Rot. Termites are attracted to weak and Rotted Wood.
Rain water and year-round morning dew, drip off of the roof tiles and onto the fascia and wood sheathing causing Dry Rot and attracting the Termites.
Gutters hide these areas from view and thus are neglected when painting the house. If you really want to protect these areas, you must incorporate removing the gutters prior to painting.
Metal edging can also be installed at the roof fascia junction so rain will run off of this very exposed wood edge. Roof Repairs can be made to eliminate water intrusion that you don't see.
