If your roof has seen better days, you may want to consult with a professional, like Surface Shield Protective Coatings, about replacing the shingles and underlying membrane. However, if you aren't quite ready to update your old roof, you'll need to protect it this spring. The spring season is known for excessive rain, which can be very hard on an aging roof. Thankfully, with these strategies, you can minimize the wear and tear on your roof and also decrease the chances of a leak developing.
Keep your gutters clear.
Wait for a nice day, and then dedicate yourself to cleaning out your gutters. Clean gutters are important for minimizing damage to any roof, but especially a roof that's on its last legs. If your gutters don't drain properly, water will accumulate on the roof, and it does not take much for that water to leak through aging, crumbly shingles.
Cleaning gutters is actually quite simple. Get a ladder and then use your hands or a trowel to scoop out the majority of the debris. Then, use a hose to flush the rest of the debris out of the gutters. Make sure the water is rushing cleanly through the downspout before you stop rinsing.
Sweep any leaves and debris off of the roof.
Leaves soak up moisture. If you leave them up there and it rains, they will trap moisture against your roof for days, which could lead to rotting and subsequent leaks. As soon as the weather permits, climb up on a ladder and use a long-handled broom to push any and all debris off the roof. Repeat this process whenever you notice any new debris accumulation. If you have any tree branches that are close to the roof, make sure that you trim them back so that leaves will have less of a chance of settling there.
Nail patch shingles over any that are badly deteriorated.
If you see any shingles that are definitely on their last legs and about to fall off, take a new sheet of shingles and nail it directly over these decaying ones. (Pull any super loose ones off before nailing the new shingles in place.) If you don't want to nail the patch shingles to the roof, use a pry bar to loosen the tabs of surrounding shingles, and then apply small beads of roofing cement to the patch before placing it on and folding the tabs back over. This patch won't look as neat as if you were to cleanly remove the new shingles and carefully put the new ones into place, but it's good enough to prevent leaks until you get around to having a new roof put on. If you use the same color shingles that's on your roof already, your makeshift patches won't be nearly as obvious as you'd think.
If your roof survives the spring, then it should be good to go throughout the summer, too. However, you should strongly consider having the old roof replaced before winter when the weight and dampness of snow can lead to major leaks.
