-
Be sure tree limbs and other vegetation are kept
away from your roof, gutters and downspouts.
-
Extend downspouts out from the house.
-
The standard rule for downspouts is that a 2 x 3
will drain 600 sq. feet area and a 3 x 4 will drain 1,200 sq. feet.
-
You should have at least 1 downspout for every 30
ft. of gutter. The gutter should be secured every 2-3 feet.
-
Use splash blocks at the end of all downspouts.
-
Gutters should slope down toward downspouts ¼ inch
every 4 feet.
-
Replace all gutter hangers that break, pull free
or become bent.
-
Leaf guard systems should always be installed on
top of the gutter not in the gutter. If your primary problem is small debris
like pine needles installing larger 3 x 4 downspouts will solve the problem.
-
Your gutters should always be installed under the
drip edge of your roof. If your current gutters are not installed this way
you could easily place a small strip of metal flashing under the drip edge and
over the back of the gutter. This eliminates leaking behind the gutter and
damage to your fascia covering.

To repair a leaking joint, clear the debris and
clean the area as described above. Scrape out old sealant. Firmly press
joint closed and coat entire area with a self-leveling butyl-rubber sealant.
