Things To Ask The Roofing Contractor During An Inspection

Construction & Contractors Blog

Putting a new roof on your home is a big investment, so you want to get the most mileage for your money. You might get by with a partial new roof, or by putting new shingles over old ones. If your roof still has a few years of life left in it, you may want to make repairs rather than put on a new roof. You'll have some important decisions to make. The first step is to have a roof inspection. These are some of the things you want to find out.

Overall Condition Of The Shingles

When you call a roofing contractor to inspect your roof, he or she will climb up on the roof and take a close look at the shingles. If you're not sure about the age of your roof, the contractor can judge the age and expected lifespan by looking at the condition of the shingles. Shingles shed granules as they age. If they are nearly bald, that's a sign the roof is old or it has been prematurely aged by the weather. Granules protect shingles from UV damage and deterioration. If most of the granules are missing, the contractor will probably recommend getting a new roof instead of just making repairs to missing and cracked shingles.

Condition Of The Deck

When the contractor walks on the roof, he or she will check the condition of the deck by noticing how it feels underfoot. It should feel solid. If it feels mushy or spongy, it is probably wet and decayed. The contractor may inspect the deck from your attic too. If there are water stains on the ceiling of your attic or signs of leaking, such as wet insulation or mold, your deck is probably bad in places. A deck can't be repaired by covering it with new shingles. The rotted portion must be removed and replaced with new plywood. This will add to the cost of your new roof and it may also affect whether you can apply new shingles over the old ones, or if you have to get an entirely new roof.

Layers Of Shingles

Another thing the contractor will check is the number of shingle layers on the deck. If the deck is in good condition, and you have just one layer of shingles, the contractor may be able to add a new layer of shingles on top of your existing roof. This saves money because the old shingles don't need to be ripped off and hauled to the dump. Your local city codes probably limit the number of shingle layers on your roof because each layer adds weight and the additional layers are more susceptible to wind damage than the bottom layer. If your roof already has two layers of shingles, your contractor will probably need to rip off the old roof and put on a new one from scratch.

With this knowledge in hand, you can decide on the most cost effective way to repair or replace your roof. The contractor will also give you an estimate for the recommended type of work when the inspection is done. If you have to delay the work until you can raise the funds, then be sure to cover the leaking area of your roof with a tarp if necessary to prevent costly water damage to the deck and attic.
