Should I repair my roof or replace it?
Repair fits when the damage is limited to one valley, one chimney or one section and the rest of the roofing is still flat, well attached and holding its granules. Replacement fits when worn shingles cover most of the roof or repairs keep failing. A roofer should explain that decision after walking the surface.
Ask the roofer to show you the sound parts as well as the broken ones. If the shingles two feet from the repair crack when bent or shed granules by the handful, a patch will not fix the real problem.
A useful rule is to ask for a second opinion when a quote for repair is large. A roofer can also give you a short list: what to fix now, and what to watch.
Why do old Rhode Island roofs fail at the joins first?
Roof joins collect and redirect water, and the materials around them move with heat, cold and settling. In older Rhode Island houses, that means valleys, dormer walls and chimneys wear out before open shingle fields do. The flat shingle surface sheds water easily; the seams are where it concentrates.
Think of the roof as a series of overlapping layers, each one shedding water onto the next. Wherever one plane meets another, all the water from the higher plane arrives in one narrow channel.
Metal flashing under the shingles protects those channels, but metal can corrode, nails can back out, and sealant dries. Roofs that have been through many freeze and thaw winters tend to show the effects at those points first.
What does a repair visit look like on a roof with several layers?
On a house with more than one layer of shingles, the roofer has to work through them to reach the leak and match the existing level. That can make a small repair slower than it looks, and it is a reason some roofers will recommend a full tear-off if the layers are worn.
Many older houses in Warwick, Cranston and Bristol were roofed again over the previous roof, so a repair means finding the true surface. The roofer may lift several shingles to find the failed nails or the actual entry point.
That is also when they notice dark or soft decking under the layers. If they do, they will show or describe it before deciding on the extent of the job.
Can a repair wait until spring?
Sometimes, if the leak is slow and the area is protected, but a roofer should decide that, not a guess. Water that reaches insulation and framing does damage you cannot see. If a section is open or missing shingles, ask the roofer about a temporary cover while the weather is poor.
Winter, which in Warwick runs roughly from early December to mid-March, is a time when cold, wet snow and freezing nights complicate repair. A roofer can usually make a temporary fix and finish the work later.
If water is entering right now, read about emergency roof tarping and mention it when you call.
