Roof Maintenance for the rainy Season

My home computer is back in service, thanks to Woody Satta my computer Guru, and my site is up and running.
With rain expected tomorrow, I thought some roof maintenance tips would be in order.
All roofs and gutters should be checked annually, preferably in September/October before the rainy season is fully upon us. With trees growing around many houses, the house movement we experience on the adobe soil in this area, and the general wear and hardening of sealants suggest a general inspection of the roof and before the rains.
Tree debris blocking the water flow, either in gutters or downspouts will cause damage by rotting out the wood in back of the gutter. Additionally, with steel gutters the tree debris will create an acid with the water (this will also happen with wood roofs due to the tannin leached from the fire retardant chemicals used) and erode the steel. Aluminum gutters will not erode but have a tendency to sag since they are not as strong as steel. Most 1st story gutters can be checked and cleaned easily. A garden hose can be used from the top, inside the gutter to clear out clogged downspouts. In extreme cases, a metal snake can be used. Seams and corners should be observed/checked during the first rains for leakage. Leaks can be fixed or retarded with caulking, however, long term you may have to call a professional for repair.
Depending on your gardener and roof type, paying your gardener a little more to keep your roof and gutters clean can be of great help to you.
